[ZenFone 2 Q&A, Help & Troubleshooting] krasCGQ:
Hi again.

1. I'm on AICP 12.1 Nightly 20161126 build.

hi everyone, i have a big problem. After installing some roms, my zenfone doesn't recognize my front facing camera (the icon doesn't show up in any camera app) i've already made some "googling" and some of the solutions were "deleting camera cache" or "format the phone" already done that, but it stays the same. A minutes ago i've installed Resurrection remix (Nougat) in hopes that i could get my front camera back but nothing happened. Is there a solution?
[ZenFone 2 Q&A, Help & Troubleshooting] krasCGQ:
1. Yep. Stock 4.21.40.134 and RussiaNBeaR. Performances are varying, so couldn't tell.

2. MM for me is better, but with slight drops on game performance.

My device was listed. Then I executed three commands consecutively. The commands were:

fastboot flash boot boot.img

fastboot flash fastboot droidboot.img

I successfully flashed these three images. After that, I unplugged my phone and tried to go to the recovery mode. But I can't enter the recovery.

Hey guys. Apologizing right away because I'm sure there is somewhere answer for me, but I'm unable to find it.

I have latest CM 13 installed on my Z00A (2/16) but I want to go back to stock fw.

I know it is possible but I would love to find step-by-step guide. I can't even remember, how I've installed CM13. It's been year probably.

Reason is, CM13 has stopped developing and side reason is, Skype app is still crashing on me. Can't even sign up.

Or is here better fw which have a active development? Need something stable as at least CM13 and where Skype could work.

Xposed would be top, but I don't belive it is working otherwise than on stock.

Using mostly: Facebook, YouTube, messenger, tapatalk, Google Drive and few more apps.

Would appreciate any help, in the mean time I will search better.

Once you've upgraded to MM bootloader, you won't be able to use TWRP other than 3.0.2-M1. Also, do a clean wipe and flash ROM + GApps and reboot to system.
