Hacking Question BOOT0 checksum mismatch

[yacepi15]

Hello,

I've made a clean NAND backup of my Switch including Boot0/Boot1 partitions and i'm going to restore it. Just in case, i've made another one of the console now, and the boot0 checksum is different.

- Both backups are from the same OS version.
- I NEVER did autoRCM.
- Boot1 is the same in both backups.

Is that normal that BOOT0 changed or one of the backups is corrupt?

This is also the case with me. hekate cannot restore the backups properly. Now you have to live with the fact that the AutoRCM can never be deactivated.

I'm pretty sure with a donor boot0 and your keys, you can get a proper recreation of your original boot0.
But don't ask me how lol

BOOT0 contains BCT, Keyblobs, package1 and other data, the other data is rewritten on every reboot, a wrong checksum doesn't mean that your BOOT0 is corrupted.
BOOT1 is a copy of the current firmware's safemode package1

@Falo
you've successfully restored boot0. SX OS AutoRCM has damaged my boot0 forever. I can't uninstall the AutoRCM. Luckily I made a backup of boot0 and 1. However, I tried to restore boot0 with hekate. Nothing's working.

I used hekate to install AutoRCM and i can uninstall it without any problem.
But i never restored BOOT0, so maybe hekate can't fully restore it?

This is true you can use someone else boot0/1 but you need your system partition which should be there is youvdid a full nand dump, but talk to someone who knows what they're saying.

I tried three times, but all my attempts failed. My switch now only boots into the RCM.

Did you use briccmii to remove AutoRCM? It's better at removing most, if not all, forms of AutoRCM. You should backup your BOOT0 and BOOT1 before using it.

Pretty sure you need to remove AutoRCM the same way you installed it, as different methods corrupt it differently

That's generally true, but briccmii works well with multiple methods.

Updating turns off autoRCM, so you can do it if you get desperate.

+1 briccmii, saved my life.
