Help Restore original recovery

[paulfourteen]

I have an LG G2 (D800) ATT, Lollipop 5.0.2 and rooted. My goal was to install Marshmallow 6.x so I installed TWRP 2.8.6.0 but unfortunately because my G2 was already encrypted I always get a critical error when I boot recovery. I did not backup my factory recovery before I installed TWRP.

• Where can I download the original LG G2 D800 recovery?
• Since TWRP stopped supporting G2 with version 2.8.6.0 can I safely install TWRP 3.x which supports encrypted phones?

I wouldn't try to work your way around it. The G2 has some significant workarounds as it is, including downgrading part of the bootstack in order to be where you're at now. It's too risky.

Instead, I would tot back to stock using the instructs here:

Then you can get back up to LP and use Bender's LP Autorec for root and recovery.

UPDATE - I successfully decrypted the phone, and I can boot normally (not bricked), so I know the encryption is not the problem. However, when I boot into TWRP recovery I still get the error "Secure boot error. Boot certification error." Does this change your previous answer? I would like to proceed with a Marshmallow update, but I need to boot TWRP recovery to do so.

I was deeply involved with this device in the earlier days but I haven't run it for the better part of 2 years now so I'm not up on the latest offerings. I didn't think the G2 was slated to get MM, so are you talking about flashing a custom rom based on MM? If so, could you provide a link to that rom? It likely has specific prerequisites which will hopefully be clearly stated. My guess is that my previous reply would still be applicable but a review of the rom thread would allow us to be sure.

Yes, these were the instructions that I was following.
