Tutorial  Updated

Backup/Restore your Nand + Get your biskeys+tseckeys+keys.txt Guide

This Multi-Guide provides instruction for the following:

Back up your NAND,
Backup your system information,
Restore your NAND,
Make exFAT work on lower system versions


Please read and follow the following disclaimer before attempting to follow this guide:

Only use the files attached, I update these when needed to ensure that they are functioning. Failure to use the attached files may result in issues.

I take no responsibility for issues you may have as a result of the use of the files or instructions contained within these guides. You execute this/these guide(s) at your own risk. I'm happy to help with any questions. Please review the comments and answers on this thread as well. I try to provide assistance when requested.

Before any modification of your system, I recommend you back-up your NAND (to make yourself a clean back-up and/or a virgin NAND). Don’t use Auto RCM until after you complete your back-up.

To follow the below guides, you will need the following:
  • A micro SD card formatted to exFAT or FAT32 with at least 32 GB of free space
  • All files attached at end of this guide, extracted to your PC
  • Fully charged Switch (or the ability to keep the Switch plugged into a power source during the restore process)
  • USB to USB-c cable (short is better)
This guide assumes you have some method of entering into RCM. (e.g. RCM jig installed or shorting pins 1+10 on the Joy-Con rail.)
You may also run the "Hekate.bin" from your own dongle or method from the
"Payloads to be used with tegra.zip" if you do not wish to use TegraGUI



For Fat32 users only >>Join RawNand Parts Mini Guide
Download this first click here > >joiner_scripts_for_windows_linux_macos.zip
to combine the 15 parts or 30 parts of rawnand00.bin etc into 1 rawnand.bin file
Place the correct script into the folder where you have the 15 or 30 parts backed up.
example
If you have 15 parts rawnand files use the join_15_2GBparts_linux_macosx.bat For Mac
or for windows use the join_15_2GBparts_windows.bat
Simply move the desired script that matches your system windows or mac 15 or 30 parts to the folder where you have your rawnand in parts 15 or 30 double click the bat file and it will merge/join those into one file called rawnand.bin
Backup Guide

In order to run the "Hekate.bin", you first need to setup and install a payload sender and the apx driver. I have provided an application (TegraRcmGUI) in the zip files at the end of this post.


You may also run the "Hekate.bin" from your own dongle or method from the "Payloads to be used with tegra.zip" if you do not wish to use TegraGUI



Steps for this are as follows:
  1. Extract TegraRcmGUI_v#.#_Installer.zip on your PC and install

  2. In TegraRcmGUI, select the “Settings” tab and then click “Install Driver”
    tegragui.png



  3. Place the contents of “SDFILES PART 1.zip” and “SDFILES PART 2.zip” and also “SDFILES PART 3.zip” onto the root of the SD card
    - Remember to format your 32 GB SD card to exFAT or FAT32 first

  4. Place the SD card into the Switch

  5. Put your Switch into RCM by holding volume up + power
    - Click this link for instructions for entering >RCM<

  6. With TegraRcmGUI open, connect the Switch to the PC
    - Before injecting, the Switch Icon will change to green and indicate “RCM OK” if Switch was
    connected correctly in RCM mode


  7. In TegraRcmGUI: Payload tab, navigate to the location of the hekate.bin on your PC and Inject payload
    (the hekate.bin is in the payloads to be used with tegra.zip)

    - The Switch Icon in TegraRcmGUI will change to orange hourglass during injection
    - If payload is sent correctly, Switch Icon in TegraRcmGUI will change to green checkmark
    - If the payload is not sent, try using a different (shorter) cable and repeat from step 5.

  8. Switch will automatically boot into Hekate bootloader (steps 9-24 take place on the Switch)

  9. From the hekate main menu, select “Console Info”
    qAGf4GB.png



  10. Select “Ipatches & bootrom info” (this isn’t in the screenshot above but should be in the Hekate Console info menu.)

  11. Follow the instructions to dump to SD card

  12. Return to Console info menu

  13. Repeat steps 10-12 for “Print fuse info”, “Print kfuse info” and “Print TSEC keys”

  14. Return to Hekate main menu (by selecting “Back” at the top)

  15. From the hekate main menu, Select “Tools”
    DvXS7dy.png



  16. Select “Dump package1/2” and allow this to run

  17. When complete, return to Tools menu

  18. “Select “Backup”
    pK6vWea.png



  19. Select “Backup eMMC BOOT0/1” and allow this to run

  20. When complete, return to “Backup options” menu (by selecting “Back” at the top)

  21. Repeat steps 19 & 20, selecting “Backup eMMC RAW GPP”, “Backup eMMC SYS” & “Backup eMMC USER” instead of “Backup eMMC BOOT0/1”
    - These may take some time so be patient. The result will be a
    - dump of Full NAND Minus the boot0/1


    - (I RECOMMEND YOU BACKUP EMMC SYS , YOU WILL NEED A EXTRA 2.61GB ON SD CARD FOR THIS..
    Used so you can recover switch in case of bad rawnand)
    ANOTHER COPY OF YOUR SYS FILES THE SAME IN YOUR RAWNAND.BIN Basically



    - (Backing up EMMC USER is Your Choice as it requires 26gb Extra)
    Used to backup your User files saves games etc


    emmc user and emmc sys are in your rawnand.bin > (eMMC RAW GPP)



  22. Return to Hekate main menu (by selecting “Back” at the top)


  23. From the hekate main menu, Select “Launch”
    SB5LCUe.jpg



  24. Select “BisKeyDump" from the Tools section

  25. Your keys will display on the screen. Follow the onscreen instructions to dump keys to SD card
    - Resulting file, on the root of the SD card, will be named device.keys
    - Rename to “biskeys.txt” if you wish.

  26. With TegraRcmGUI open, connect the Switch to the PC

  27. In TegraRcmGUI: Payload tab, navigate to the location of the Lockpick_RCM.bin on your PC and Inject payload... (Lockpick_RCM.bin is in the payloads to be used with tegra.zip)
    - You should now be presented with a freaking rainbow
    - It will automatically dump your keys to your SD card to the "switch folder" the file will be named "prod.keys"

  28. Press the power button on your switch.
    - Once powered off remove your SD card and put it into your pc.
    -You can now close Tegra and remove USB cable from switch to pc, if still connected.

You could also read the exFAT guide on my main post if you're having trouble running CFW or accessing Homebrew menu to update your lower system version to have exFAT support


If you have an error when trying to use Goldleaf, please try the Goldleaf Error Guide below.
If you don't, you can skip Goldleaf Error Guide


Goldleaf error guide
A Big Thanks @shchmue for sorting out the bugs and for her work on the Goldleaf issues.

Ensure you have a complete set of dump files:


Dump all the console info using the payload I included hekate.bin
(the hekate.bin is in the payloads to be used with tegra.zip)


  1. From the hekate main menu, select “Console Info”



    - Console Info -> Print fuse info -> Press power button
    - Console Info -> Print kfuse info -> Press power button
    - Console Info -> Print TSEC keys -> Press power button

  2. From the hekate main menu, Select “Tools"


    - Tools -> Backup -> Backup eMMC BOOT0/1

    - Tools -> Dump package1/2
  3. Ensure all of the following files are on your SD card:
    - /switch/Goldleaf.nro

  4. In the backup folder on the SD card, inside the letter and number folder, open folder dumps. Confirm the following files are present:


    - fuses.bin
    - kfuses.bin
    - tsec_key.bin


    If you’re missing one of the above .bin files, follow the Console Info instructions (above) to dump them again.
  5. In the pckg1 and pckg 2 folders on the SD card, confirm the following files are present:


    pckg1 folder
    - nxloader.bin

    - pkg1_decr.bin
    - secmon.bin
    - warmboot.bin

    pckg2 folder
    - ini1.bin
    - kernel.bin
    - pkg2_decr.bin


    If you’re missing one of the above .bin files, follow the Tools -> Dump package 1/2 instructions (above) to dump them again.
  6. On the SD Root, confirm the following files are present:


    - Boot0
    - Boot1
  7. In the backup random number letters folder, confirm the above files are present as well.



    If you’re missing one of the above files, follow the Tools -> backup emmc BOOT0/1 instructions (above) to dump them again.

    If they are missing from one location or the other, they can be copied to the location where they are missing.
Try the Goldleaf.nro again


Before you continue



It has come to my attention that some windows 10 operating systems with builds 1507/1511/1607 will experience an issue transferring nand or switch system files from PC to your SD card or Switch. This issue results in missing bits in the copies of the archive bits, needed for the switch to operate correctly or restore of nand to work.

Our member here @Draxzelex was nice to point this out :teach:, so I thought I would add it to the guide.

If you’re on one of the affected versions of Windows 10, before transferring your files, it is recommended to use a third party application called Total commander to transfer the backups to your SD card or even when you’re moving the backup folders on PC

To check your windows 10 version:

Go to windows search by clicking the windows key (start)

Search for ‘about your PC’ in the search bar, and select ‘About your PC’ in the search results

On the right-hand side scroll down to Windows Specifications

In this section, you will see your build version

If you are above build 1607 you can ignore this information in blue.
If you are not above version 1607 then either please use Windows Update to update your build or use Total commander to move your backups around your PC or to SD card


Instead of using Total commander, you could try a method of using a compression zip/rar program like WinRAR to archive or compress the backup folder on your SD before you even think about transferring to PC, and when you go to move backup back to SD card transfer your zip or RAR to SD then extract it from there
clip_image002.png
(Not tested )



You may Continue


29. On your PC make a folder where you're going to place your backup switch nand and files



30. If you used lockpick to backup your prod.keys then Open your SD card on your PC and copy the prod.keys from the switch folder on the SD card to the folder.



31. Copy the entire backup folder from SD card to your backup folder on PC.



32. Please zip or rar the backup folder once you have transferred it on your PC
this will also save space.



Also, save the biskey.txt and prod.keys You made earlier to your backup folder
Once you backed up to your PC

And that's it.


I hope this may of helped you all or i just wasted hours of my life here


You can skip the guide below if your only backing up your nand and keys

Restore Nand Guide
I take no responsibility for issues you may have or if your system fails to boot after restoring your NAND.
You do this at your own risk!

Please make sure to read the blue text in my Backup guide above when you made your backup

To follow the below guide, you will need the following:

Make sure your battery is charged (at least enough to complete the restore process) or keep the switch plugged into a power source (USB cable should be fine)

Restoring your nand.....

Providing you have followed my guide above to back-up your NAND, you should have the 3 required files in your backup folder
(Plus some other files we won't be using for your restore)


- boot 0

- boot 1

- rawnand.bin

If you do not have these files please do not continue

  1. From your number and letters folder inside the backup folder on pc, copy the below files to the restore folder on your SD card


    - Boot 0
    - Boot 1
    - rawnand.bin



    Example on sd card
    inside The folder on SD card Backup>numberletter folder>restore folder <....place files here...
  2. Place the SD card into the Switch

  3. Put your Switch into Rcm Mode

  4. Boot into the hekate bootloader *Hekate.bin* By using tegrarcmsmashGUI
    SB5LCUe.jpg


  5. From the bootloader hekate main screen, select tools option with the volume +/- buttons and press power button to select




  6. In the tools section, Select Restore
    DvXS7dy.png





  7. In the restore options screen, select “Restore eMMC BOOT 0/1”
    - You will be warned and asked if you are sure. To continue, press the power button and wait for the process to finish.
    - Once finished press any key to go back (do not power off at any time)

    cwvD6Db.png





  8. Still in the restore options screen, select “Restore eMMC RAW GPP”
    - You will be warned and asked if you are sure. To continue, press the power button and wait for the process to finish. This will take some time.

    - Once finished press any key to go back (do not power off at any time)
    cwvD6Db.png





    Now assuming all the processes went smoothly and you got no errors you should now be restored!
  9. Go back to the Hekate main menu by selecting back
    SB5LCUe.jpg





  10. On the main menu select power off.




  11. Reboot your switch as normal with the power button


If all went well, you should now see the Nintendo logo and should boot back into the main OS of the switch.


Well done you successfully restored your NAND!!

Did you sh*t your pants ??? :shit::lol:



Again I take no responsibility For backing up and or restoring your NAND, this is a dangerous process and you do it at your own risk.

Exfat Update Guide For
Lower System Versions
At this time I have not made the exFAT guide myself so until I do I thought I’d link to another exFAT guide,
Please like his thread if it helps you and mine if you like the information I’ve provided


Method 1 (Not as easy but doable)
Method 1 Link
Method 2 (A lot easier)
Method 2 Link



Info taken from Method 2


Q: I just want to install exFAT on the current firmware version I already have. Can I do this using ChoiDujourNX?


A: Absolutely, just place a folder containing the exFAT version of the firmware you are currently running and choose it inside ChoiDujourNX. It will only install the required couple of packages needed for exFAT, and you can even disable the AutoRCM option (if you are sure the firmware you are installing is the same burned fuse count as the one you are currently running).

If i have helped you, Or you like my post
Then Please hit that like button it will help me a'lot thank you

Ok so backup done, green text said verified. Wanted to get the keys, so selected cfw and when it booted up, said the micro sd card is corrupt and it needs to delete eveything! So ejected the micro sd card and now copying the backup folder to the PC 28.6GB freshly formated switch with just one user file.

Using a samsung evo 128gb card.

Is this a known issue?

edit: using a 4gb card now, copied contents of backup folder to sd card and removed user and system files as they are really big and it loads up keyplez but get the error message.

How are you trying to run kezplez what cfw method are you using ?
whats your sd card format

Try removing the leters and numbers and just have the folder called backup
Kezplez may not read the new folder name.

The SD card format is exFAT and I used the included SD files to launch the CFW with the hekate payload. I get the same error with ReiNX and RajNX, though. I also tried moving the backed up data to another location. But the file structures
  • root
    • backup
      • dump etc...
and
  • root
    • dump etc...
don't work either.

kezplez relies on some of the dump files.. in the kezplez error guide make sure to have those files on your sd..

and

The files need to be in the backup directory.. and match the kezplez error guide structure....
What system version you say your using ?, and does another homebrew app load ?

--------------------- MERGED ---------------------------

i backed up but when i try to restore the nands i get errors?
What error are you getting? telling me you get a error is not very informative
To restore you need rawnand.bin boo0 boot 1
Exfat sd card.



Information... https://github.com/tesnos/kezplez-nx/releases/tag/v1.1

FYI the hekate version in my files does dump tsec...
Also please check error guide..
And match folder structure,
I did not build or make kezplez and am tired of receiving kezplez error questions..
I will help but im not a expert with that homebrew app..
Most error are down too missing files, system versions , and exfat/fat format..
And bad sd cards.

I followed that structure and even did what LazyJones did but still error.

What is the keys for exactly?

Decryption, choirdujour,hactool, basically for the nca files games etc conversion. those tools that ask for the keys files.

Like i said the folder needs to be called backup.. and everything should be in that folder.
There are only a thew that have these errors, but seen as none of you are providing me with the exact issue error code, or system your on or format , what am i suppose to do but guess.

Ok so should the backup folder be left intact as it is when it backed up the nand? Is there no other way to get the key file?

Using in 5.1.0 switch exfat card

5.1.0 sir you should be having no issues at all...
5.1.0 high success rate with kezplez..
Yes of course it should, if you remove files or change the folder names its not going to work.
Kezplez cannot read your mind or go looking for what it needs.. Kezplez relies that your backup is untouched and has the required files it needs in the directorys its looking in....

The only difference is the new hekate version 4.0 changes the backup folder name and adds numbers and letters..
Chage the backup folder from backup12345abc to backup

And make sure you have the correct files in the correct folders and have them all , look at the kezplez error guide.

And also make sure you can run other homebrew apps

Think you should use your 128gb card formatted to exfat,
and put the backup folder back on your sd card, and the attached sd files then check for missing files from the error guide.

Posting pics of the files in there folders helps.

@ganons @Lazyjones
Does your system, nintendo software aka horizon have exfat support ?

@Roxasorg13
Can you provide any information to these two how you fixed your errors or your process ?

yes exfat

sd root\backup\e32db8d8\dumped files etc

also in the root i copied the boot0&1 from the dumped files. So boot files are in the e32db8d8 folder as well as root.
Also tried by having the dumped files in \backup and not e32db8d8 but still doesnt work

keyplez was tried with the dump structure untouched

other homebrew such as gc dumptool works

This Multi Guide Will help you back up your nand, Backup your system information,
Restore your nand, and also Make exfat work on lower system versions.

Only use the files attached if your following my guide/thread
I also recommend you Backup your nand before any

modification of your system to make yourself a clean backup / A Virgin Nand
Also not to use auto rcm Until after your backup

You may also run the "hekate.bin" from your own dongle or method from the

"Payloads to be used with tegra.zip" if you do not wish to use TegraGui


Preparation:

You will need a micro sd card formatted to exfat with atleast 32 gb Of free space to follow this guide and guides.


You will need to download the files i have provided
Download all Files attached at end of this guide,And extract these first to your pc


Backup Guide

Ok lets try keep this simple Backing up

Firstly
you will want to set up and install your payload sender TegrasmashGui to
and install your apx driver
tegragui.png

and then put your Switch into Rcm Mode by holding
volume up + power with your rcm jig installed or shorting pins 1+10 on the joycon rail..

Secondly
Drag and drop the files in the sdfiles.zip attached, onto the root of the sd card
Now place the sd card into the switch

Thirdly
You Send the attached hekate.bin to your switch with Tegra Gui
Once your switch boots into hekate bootloader
Select Console Info

qAGf4GB.png

then select print fuse info , kfuse info , Tsec keys, and battery info if you wish Individually
When you select these options it will give you the option to dump each of these with the power button.. so go ahead and do that.
Once you dump them,Go back

Then you Select Tools Option In hekate

DvXS7dy.png


and Dump package1/2 once completed select back

Then select Backup option


pK6vWea.png


Then Select Backup Emmc Boot 0/1 Once this is backed up
Press any button volume or power
Then select Backup Emmc Sys Once this is backed up
Press any button volume or power
Then Select Backup emmc Raw Gpp
(Now this will take some time to complete be patient This will dump Full Nand Minus the boot0/1)
Once this is backed up
Press any button volume or power

Ok so thats your nand backed up.... And info placed in the backup folder in your sd card

Now for your keys

Go back to hekates main menu

SB5LCUe.jpg


Ok now select Launch option on hekate main menu,
Then select Biskeys From the tools section by pressing the power button


On the screen is your biskeys and other info take note of these or use a qr scanner app on your mobile/Cell phone,to scan the Qr code Some Qr scanner apps have a feature to send the scanned file in text format to a email address do this and open your email and save the info to a text file called biskeys.txt


Ok

This section below about booting into CFW may not work for all of you on some system version, or if your not using exfat. Do not panic or worry about this, as the keys.txt file can be taken from your switch in any of the CFW methods like reinx ,rejnx ,SXOS, atomosphere.Basically any method you can launch into Homebrew menu to load Home bre app Kezplez. you could also read the exfatguide On my main post if your having trouble running cfw or accessing homebrew menu to update your lower system version to have exfat support

So now you will need to restart your switch and load back into the hekate bootloader menu to do this load the hekate.bin in the tegra gui, hold the power down and volume up then inject the payload.

Once your back into the Hekate menu you will want to go to Launch option

Then select CFW to load custom firmware,

After this Select album twice on switch main menu Once loaded, you should load into Homebrew menu,
from here select kezplez and launch it... you should now be presented with a freaking rainbow
Press A on joycon to begin to dump your keys.txt to your sd card. You will be notified once this is completed

If you have a error When trying to use kezplez, Please Try Guide Below,If you don't you can skip Kezplez error guide

Kezplez error guide

Make sure to Use the files i have uploaded Especially
kezplez-nx.nro and kezplez-nx.nacp
and ipl.bin as your bootloader (As this bin lets u dump tsec which is probally your problem

Yes make sure you dump all the console info use the payload i included hekate.bin

In Bootloader Goto Console Info

  • Console Info -> Print fuse info -> Press power button
  • Console Info -> Print kfuse info -> Press power button
  • Console Info -> Print TSEC keys -> Press power button

Then Goto tools in bootloader menu

  • Tools -> Dump package1/2

MAKE SURE
kezplez-nx.nro and kezplez-nx.nacp is in

/switch/kezplez-nx on your sd card


Checking to make sure you have the files on your sd card

In the backup folder on sd open folder dumps
in this folder should be

  • fuses.bin
  • kfuses.bin
  • tsec_key.bin

If your missing one then dump it with console info again

On sd also should be

pckg1 and pckg 2 folders which is dumped from the tools section on bootloader
called dump package 1

pckg1 folder on sd
in there should be

  • nxloader.bin
  • pkg1_decr.bin
  • secmon.bin
  • warmboot.bin


pckg2 folder on sd
in there should be

  • ini1.bin
  • kernel.bin
  • pkg2_decr.bin

And also on sd root
should be

  • Boot0
  • Boot1
Which is dumped in boot loader
via backup options
backup emmc BOOT0/1



If you do not have boot0 and boot 1 on your sd card root then please copy them from the backup folder aswell


So please make sure you have all those files in those folders on your sd

then try the kezplez.nro again


Last but not least
Hold down the power button on you switch then select power off.
Once powered off remove your sd card and put it into your pc.
You can now close tegra and remove usb cable from switch to pc.



Before you continue

It has come to my attention that some windows 10 operating systems with
builds 1507/1511/1607 will suffer a issue were when your transferring nand or switch system files from pc to say sd card or switch Will not copy Archive bits correctly which is needed for the switch to operate correctly,or restore of nand to work ..Our member here @Draxzelex Was nice to point this out :teach::yay: so i thought i would add it to the guide before transferring your files, he recommends using a third party Application Called Total commander To transfer the backups to sd or when your moving the backup folders on pc, If your on one of those affected versions of windows 10

To check your windows 10 version
Goto windows search by clicking the windows key (start)

and type.... about your pc in your search bar, select about your pc in the search results and on the right hand side scroll down to Windows specifactions there you will see your build version if you are above build 1607 then ignore the information in blue.
If you are not above version 1607 then either please use windows update to update your build or use total commander to move your backups around your pc or to sd

Or to play it safe you could try a method of Using a compression program zip rar program like winrar to archive or compress the backup folder on your sd before you even think about transferring to pc,, and when you go to move backup back to sd card transfer your zip or rar to sd then extract it from there :) (Not tested )


You may Continue

On your pc make a folder were your going to place your backup switch nand and files
Open your sd card on your pc and copy the keys.txt from root of card to your folder then copy the entire backup folder from sd card to your backup folder on pc.

Please zip/rar the backup folder once you have it on your pc
this will also save space

Also save the biskey.txt You made earlier to your backup folder


Once you backed up to your pc
Now erase your sd card so theres no conflicts with other files u may use or other guides
And thats it..


Sorry about the mess of the guide maybe someone could clear it up for me :P
I hope this may of helped you all or i just wasted hours of my life here

Thank you to all the Hosts of the threads/Guides and creators of the files i used your doing awesome work and i appreciate it...

You can skip the guide below if your only backing up your nand and keys

Restore Nand Guide
I take no responsibility for issues you may have or if your system fails to boot after restoring your nand
Do this at your own risk And please to make sure to read the blue text in my Backup guide above when you made your backup
Also Make sure your battery is charged Or atleast enough to complete the restore process to be safe fully charge the battery Or keep the switch plugged into a power source usb cable should be fine
Also please make sure your sd card is in exfat format (Important)

Restoring your nand.....

Providing you have followed my guide above to backup your nand
You should have 3 Files in your backup folder

(Plus some other files we wont be using for your restore)

boot 0 boot 1 rawnand.bin

If you do not have these files please do not continue


Step 1
Make a folder on your sd card called Backup
Inside that Folder make another folder called Restore

Step 2
Copy from your pc Boot 0 and Boot 1 and Rawnand.bin
and place them in the restore folder on your sd card

Step 3
Put your Switch into Rcm Mode
Boot into the hekate bootloader *Hekate.bin*
By using tegrarcmsmashGUI

Step 4
Now once your on the bootloader hekate main screen

You will be warned and asked are you sure. to continue press the power button and wait for the process to finish Once finished press any key to go back (do not power off at anytime)

Step 6
Still in the restore options screen

Select RESTORE eMMC RAW GPP and press power to continue
You will be warned and asked are you sure. to continue press the power button and wait for the process to finish now this will take some time Once finished press any key to go back (do not power off at anytime)

Step 7
Now considering all processes went smoothly and you got no errors
you should now be restored
Go back to the Hekate main menu by selecting back

On the main menu select power off.
Then reboot your switch as normal with power button.
If all went well you should now see the Nintendo logo and should boot back into the main OS of the switch

Info taken from method 2




    • Q: I just want to install exFAT on the current firmware version I already have. Can I do this using ChoiDujourNX ?



    • A: Absolutely, just place a folder containing the exFAT version of the firmware you are currently running and choose it inside ChoiDujourNX. It will only install the required couple of packages needed for exFAT, and you can even disable the AutoRCM option (if you are sure the firmware you are installing is the same burned fuse count as the one you are currently running).


If i have helped you, Or you like my post

Those files should of not made a difference,, as the ones i have provided are those files but updated.
I've also been getting the error right away with kezplez when I tried recently even though it worked back when 3.2 was current. I wonder if newer hekate options actually keep it from running. I'll try some stuff tomorrow.

Gambia, The
got the rawnand.bin now and deleted the USER file but still same error

edit: finally got it working by using the hekate 3.2 and the sd files from here https://github.com/Jan4V/hekate-ipl-50x/releases/tag/v1.0.0

folder structure is set up as root/backup/dumped files

I'm in the exact same situation, 5.1 and exFAT. Gonna try the older hekate later.

edit:
File structure looks exactly like in post #210 and I used hekate 3.2 and the linked SD files. Now I don't get an error, but instead only a black screen when opening kezplez. Other homebrew like tinfoil work fine.

I got a blackscreen also. Make sure you put in the SD files from the link I posted and use Hekate 3.2 again
