I did a stupid mistake this afternoon. I downloaded the System UI Tuner app and tweak the status bar to only show ONE quick setting tile upon first swipe down (obviously wont work but idiot me still think that it is a good idea to give it a try anyway). Upon pulling the slider to 1, the System UI crash immediately and only show black screen and everything stopped working. I am desperate now and really need kind people here to help me troubleshoot this to reset and get System UI working again. I will list down some background and information below.

Device: Asus Zenfone Max Pro M2 Just updated to Android Pie today

What is working now: - Power Menu - Safe Mode - Google Assistant - Stock Recovery - Fastboot

What is not working (Can't find a way to make it work): - System UI - ADB (USB debugging was turned on but I cannot authorize my phone without System UI) - Unlocking the screen - Boot loader not unlocked - Internet (Data was not on before crash and WiFi require me to sign in)

What have I tried: - Turn it off and on - Boot into Safe Mode - Wipe Cache in Recovery - Flashing the same firmware again with recovery

Kindly request if you need more information.

Of course, the last resort is to do a factor system reset but I really wish I can keep my precious stuff in my phone... and also I've set up my phone to act as 2 factor authentication for my Google Accounts which I might be a problem if I reset my phone.

Thanks In Advance!

  • Given that bootloader is locked (so no access to a custom recovery) and USB Debugging not working, I see no way to solve this without factory reset. As for 2 factor authentication, if you stored recovery/backup codes as an alternative way to authenticate you don't need the phone at all.
