Hacking Restore NAND from partitions?

[wurstpistole]

I think I bricked my switch. It only loads the logo, then a black screen. I've tried restoring the GP partitions. Nothing. How do I do a full rawnand restore?

What exactly did you do?

Hi everyone,

First question, what firmware introduced the exFat format for the Switch?

Second, how to I restore my NAND, I currently have it in 14 partitions. I can't restore from hekate as it requires exFat with the single rawnand.bin file or the restore from partitions looks for the individual sections stored within the bin.

Any help would be appreciated.

on the github page of were you download hekate
there is a script you can use to merge those partitions into rawnand.bin

what r u meaning load os anymore?
your console back to stock,you need to send the payload again via tegra rcm.

Do you have your original 14 parts nand back up ? for the sytem update your using

Like i said Join your 14 files with this
https://github.com/CTCaer/hekate/releases/download/v3.2/joiner_scripts_for_windows_linux_macos.zip

then format a 32gb or higher sd card to exfat,,place all the files of SDFilesV521 by tom ger on root of sd, and place the raw nand.bin u just got from the script into Backup\Restore Folder
Put switch into rcm mode ,Load hekate payload with tegra and usb cable to pc
goto
Restore and restore raw nand.

this will remove auto rcm

I dont have AutoRCM. I was just testing restoring NAND and thats what made my switch stop working.

Not CFW, it won't load stock OS.

Even if you didn't have autorcm, I would boot up the briccmi payload and check if something is corrupt.
I had the same problem almost as you, but after being stuck on the black screen I couldn't even turn my switch on without removing the emmc.
I fired up briccmi and it fixed everything.

Just tried running briccmi; still having a black screen after logo.

Yes, said all were correct.

 

[Mr. Wizard]

Yes, said all were correct.

Bummer.

Yea after my ordeal I've learned not to fuck with the nand unless absolutely necessary lolz.

Maybe someone else who's had the boot loop problem will chime in.

Thanks for trying to help. I'll try a full nand restore when I get home and will report back here.

Does any one know why new hakate 3.2 payload not give me any option to choose?. After I get into rcm and load hakate 3.2 from my NX Android it just show new logo hakate then load stright into CFW. They use to have lot of option like normal cfw layeredfs etc. Do I have to edit hekate.ini?
