Homebrew Unbrick using a9lh?

[I_AM_L_FORCE]

Yeah. I bricked sysnand but I still have a9lh installed and can still boot my emunand. Help?

 

[VinsCool]

If you could boot a bin file of otphelper through the a9lh, you could restore the sysnand I guess.

 

[Urbanshadow]

By any chance have you made a backup of sysnand with a9lh installed?

If you could boot a bin file of otphelper through the a9lh, you could restore the sysnand I guess.

There's also an a9lh-bootable version of Decrypt9 that could be used for the same purpose.

 

[I_AM_L_FORCE]

By any chance have you made a backup of sysnand with a9lh installed?

No, I have a normal sysnand backup though. Can I flash that then reinstall it?

 

[VinsCool]

No, I have a normal sysnand backup though. Can I flash that then reinstall it?

yeah, it will be fine.

 

[Urbanshadow]

Yeah it will be fine, but keep in mind you'll lose any changes to sysnand and a9lh. As you say, you will have to reinstall a9lh. If I were you I would search a way to do an unbricked CTRNAND backup with D9 or something (CTRNAND != full nand). That way you could recover from bricks without touching a9lh.

How would I make this CTRNAND backup?

 

[Phantom64]

Download the Decrypt9WIP all-in-one, you will find a decrypt9wip.bin inside of it, rename it "arm9loaderhax.bin" and boom, decrypt9 at boot0.

 

[Urbanshadow]

How would I make this CTRNAND backup?

Idk, you are on your own there. Perhaps decrypt9 has a CTRNAND partition dump/restore option but I could be wrong.

 

[Phantom64]

But yeah, you will lose your arm9loaderhax.

Oh the wii times. 3ds has no boot0/1/2, just bootrom.

Idk. Ok

It's firm0 and firm1 afaik

 

[Urbanshadow]

It's firm0 and firm1 afaik

Bootrom starts first. Someone has to decrypt the firm partitions before booting them
Also, like boot0 in the wii, is a rom (hece the boot-rom name).
This is also named by ninty this way, as in hardmod systems you can see bootrom errors
with the blue screen saying "BOOTROM" and the error code.

 

[TheReturningVoid]

It's firm0 and firm1 afaik

BOOTROM checks FIRM0 and loads it if it passes a signature check, otherwise BOOTROM loads FIRM1.
If FIRM1 doesn't pass a signature check, it's a blue bootrom screen.

FIRM0 and FIRM1 are basically the same. FIRM1 is just there as a backup in case FIRM0 gets corrupted somehow.
