Backup your current NAND, then restore your 9.2 NAND backup, and do the downgrade again to 2.1, grab your otp.bin, then restore your current NAND.So my Hard drive died and I lost my OTP, never backed it to my Gdrive. Is it possible to get it again? Do I need it? My 3DS has A9LH on it already.
Well if I don't need OTP currently then I guess I won't bother. I remember having supposed to have it backed up, but @xtheman166 made a valid point that OTPless doesn't even use it so why bother going back for it? And the thought just occurred that if I lose my A9LH abilities, chances are I will be on a FW I cannot put it back onto at this point.If you're on A9LH CTRNAND Build & Luma3DS 6.6.
Follow what @Jayro said, when you go back to 9.2, you have to remove A9LH first using lastest SafeA9LHinstaller, then contiune.
When I try to get OTP from my OTPless one, it always give me an error.
I agree, when I did I have to be careful Or I'm losing A9LH. Just added info if you really need it.Well if I don't need OTP currently then I guess I won't bother.
