Hacking AGB_FIRM patched, will I be okay with downgrading?

[theinternetnomad]

Hi, so currently I'm on 10.6 reinand on my new 3ds XL with a patched agb_firm that allows the installation of gba injects. I was wondering if it was possible still for me to downgrade to 2.1 and get my OTP and all that without risking a brick? I would rather not have to reflash 9.2 all over again since the otp process is already fairly time consuming.




Thanks.

I wouldn't risk it, just flash back an original agb firm and downgrade, I had TWL firm patched on my emunand when downgrading to 2.1 and it had and error.
It didn't brick emunand but it was an incomplete downgrade, flashed a vanilla emunand i had and then redid the process and it downgraded without a hitch.

AGB Firm is not needed outside of GBA virtual console, and while downgrading it should replace it with the original version, so there should not be a problem.

I'm pretty sure it says on the guide that it can cause errors.
