Hacking Need Help Restoring Backup / Help Unbricking Switch

[DaikuroX]

My switch is stuck on nintendo logo and no longer boots but charges. This happened while playing Megaman on Atmosphere 8.1.0, prior to being bricked, i made a backup using REINX on a lower firmware version. My question is, Can i used that lower firmware backup to RESTORE/UNBRICK my switch? What steps should i do and follow? Hope someone can help me out.

Did you backup both Boot0/Boot1 and the Rawnand?

Yes, you can restore an old NAND backup, even if it's a lower system version. You also need to restore the BOOT0/1 backups that comport with the system version the NAND backup was on.

I have boot1, boot0 and rawnand.bin.00 to 07

Then yes, you can restore this backup. Your system will refuse to boot without a custom bootloader like fusee-primary or Hekate due to a fuse mismatch, but you can update your system after you restore the old backup.

Check if it is ~29.1GB

Looks like an incomplete NAND, you need 00 to 14

Damn, what a bummer. Can i still try to restore it?

Yes, you can restore the backup, but you will need to boot through rcm untill you update back to your current fw.
If you want to be extra safe, do another backup now.

I never done any backup with ReiNX method, but check your NAND size, if it under 29GB then it probably incomplete.

 

[DaikuroX]

My backup size is only 16GB including Boot0/Boot1 and all rawnand.bins

Do a backup now and try it. Otherwise this is an incomplete backup.

My switch is already bricked and not booting, can i still do a backup? btw its already in 8.1.0 while my backup file came from an earlier fw

You can always boot payloads. So do a backup via hekate (idk how you did it on reinx, but always do a backup via hekate and never when in os).
Save this backup somewhere safe and once you are done with it, restore the old backup and try if it boots (you have to boot through rcm). If it won't work, you can restore this nonfunctional backup, but at least you wont have a franken fw.

Did you change anything recently? Updating firmware, installing NSPs, running any homebrew that messes with NAND, that kind of thing?

 

[DaikuroX]

No

No, just playing Megaman on Atmosphere 8.1.0 then it hanged, flash the atmosphere error and then no longer boots

Maybe run Check Disk to make sure the SD card is not corrupted (if one of the Atmosphere or Hekate files got corrupted it might be enough for it not to boot)
To run a thorough scan run this in command prompt: chkdsk X: /F /R (where X: is your SD card) otherwise only a quick scan is performed.
After that overwrite the Hekate and Atmosphere files with fresh ones from the release archives (and get the sig patches again too just for good measure)

Have you tried booting OFW?

 

[DaikuroX]

Yes, i tried booting to OFW, no dice, plainly stuck on logo
