Hacking I bricked my switch , please help!!!

[TrObAs]

No success with the jigs I made switch does not do anything , maybe the jigs are not ok. I tried to find keys file but every files i find it get error nca header . I do not know what should i do

No logo at all I only see a black screen nothing else.

I found the prod.keys files in my SD also I made a Nand backup before my switch stop working completely. There is a 27gb Backup folder in my card. The problem is that I found 9.1 keys but something is wrong and I get an error

If you have a NAND backup, then you should be ok. You just need to restore it. Concentrate on finding a reliable way to enter RCM. Get a jig... order one, borrow one, steal one or make one, whichever works. You just need to use it once, in theory. Then you can install AutoRCM. You could also mod your right joycon like I did, but that's probably overkill.

You picked fat32. Your switch can’t read your exfat memory card.

Format your card (or a different one) to fat 32 so your switch can read it and then place the necessary boot files.

It’s not rocket surgery.

I cannot make the jig to work so I try the guide that was posted but i am having problem with hactool keys.txt. I try to extract the keys from my nand backup and after I have joined the filed to make them one big 30gb file the program just freezes. How should i try to export the keys??

I did format my card to fat 32 but nothing changed

The prod.keys file you found on your SD card should be your keys. Rename to keys.txt, or whatever filename choidujour is looking for.

 

[TrObAs]

I tried it does not work, Thats why I try toextract the keys from my nand backup because every file i havefound for keys does not work

 

[Assasin1990]

@TrObAs , man and what you are about to do if you'll get keys and choidujour working ? USELESS untill you can't enter RCM , no RCM no life for your switch. YOU NEED TO RESTORE NAND TO SWITCH not to use any choidujour you found there. god you don't get what you are doin.

Is your NAND backup done before downgrading with choixdujour? If so all you need to do is to restore it via hekate.
From what I understand you're having trouble merging the separate files into one?
Mod your right joy-con like I did, that's far easier for you to get into RCM.

 

[TrObAs]

I did try to mod the joycon but with no luck. I did the nand backup after downgrade to 4.0.1 . No the file have been merged fine , the problem I have is I try to follow this Guide that another user suggested https://switch.homebrew.guide/usingcfw/manualchoiupgrade#step-1-preparing-files and I cannot extract the keys.txt that are needed to continue the process

 

[Assasin1990]

Put the console to charge for a couple hours , after that try to enter RCM.
Please understand your problem is you can't enter RCM.

The main issue is that you did downgrade and fuses doesn't match, so you can boot only through custom bootloader (hekate , fusee-primary).
The second issue is that you did downgrade without system reinitialization, that's why the console hungs on boot even with "custom bootloader".

Now to get the console working you need : 1) Enter RCM. 2) send Hekate and restore your backup.
that's all ! Don't search any other guid , waste of time, all returns to RCM.

You don't need any keys wtf. stop right there and do what people are telling you !

 

[TrObAs]

Thank you very much. The last two days I have trying more than 8 hours to make my switch work again.....Your information was very helpful. I have left all day the switch charging and if the jig I will try to make again fails tomorrow I will receive a proper jig the give it a try.

I will let you know what happened !!!

I would like to thank everyone for all the helpful information you shared with me.

Good news I have recovered my nand. Now I am back to to first problem I had. I cannot boot custom firmware , I boot hekake 5.1 , i choose custom firmware and I only see a logo and then black screen. What is the next step i need to do ?

 

[Assasin1990]

after you boot custom firm - > hold down volume - and + at the same time until you get in recovery mode

 

[TrObAs]

I get in recovery mode but after I choose custom firmware nothing after the first logo. I just checked console info and i see under fuses > Burnt Fuses (0DM 7/6) : 10-0

 

[Assasin1990]

1) get in RCM.
2)send an custom bootloader (hekate) choose what ever custom firm.
3) hold down volume - and + at the same time until you get in recovery mode.
4) reinitialize (wipe data) system.

OR

1) get in RCM.
2) send an custom bootloader (hekate) and restore your nand backup from sdcard.

DONE, your switch should get in HORIZON OS (switch OS) for now

 

[TrObAs]

I got in rcm mode , then i restore my nand back up (both emmc boot0 + boot 1 and also emmc raw gpp) . After whatever i choose to launch original firmware / custom I see nintendo logo or atmosphere liogo and then black screen

 

[TrObAs]

After many many tries I had no luck , so until someone suggests something I tryed the guide I posted earlier. I have found the key.txt just to see if I can do anyhing with it and the keys match only with the 4.0.1 firmware but then I got stuch again at the memloader step which failed to connect to the usb.....

I am so angry right now , so many hours and back to the same spot.....

 

[Assasin1990]

could you record what you are doin and what's happens please , cuz I'm telling you to enter recovery mode but you are telling me you choose custom firmware from recovery , from recovery you can only update or hard reset the console.

 

[TrObAs]

Sorry if I am confusing you , I will tell one by one the steps I make.

1. I boot console to RCM mode
2. I send the Hekake payload 5.1.1
3. Console boots in Hekake
4. I have restored with Hekake my BOOT0 + BOOT1 , eMCC RAW GPP
5.turn off console
6. I copy to my SD the latest Atmosphere version from the PC
7.Turn on the console in RCM mode (I tried to boot without RCM mode but nothing happens)
8. I send the Hekake payload 5.1.1
9. I choose Launch
10.I have three choices 1. CFW (SYSNAND) 2. CFW (EMUMMC) 3.Stock (SYSNAND)

Whatever of these choices I choose 1 or 2 I see a logo of atmosphere then black screen and nothing happens. If I boot to stock I see nintendo logo and after that black screen.

These are the steps I make.


For recovery mode I have tried these steps you told me but nothing happens

1) get in RCM.
2)send an custom bootloader (hekate) choose what ever custom firm

I only see a black screen after the nintendo logo (if i try stock firmware) or atmosphere logo if i boot custom firmware.) So I cannot go to step 3+4

3) hold down volume - and + at the same time until you get in recovery mode.
4) reinitialize (wipe data) system.


I am starting to believe that the console has no firmware at all and thats the reason it shows the black screen but thats just my guess or my NAND back up is not correcty
