mtk: lockscreen crash in any rom after full format
mtk: lockscreen crash in any rom after full format
(29-01-2020, 06:20 PM)steel71 Hi, yesterday I accidentally reflashed stock rom with format all + download in sp flash tool. I restored my imei, and everything works, however when i restored my twrp backup, lockscreen crashed when i insert the right pin. therefore, I removed the pin from recovery, and after, I got access to the rom. However when I tried to set the pin again, in security settings, settings app just crashed. I think I could fix this problem with a simple data wipe, however that didn't work, and it seems that after that format all + download I did, I have that problem on all stock ROM versions. Also, I flashed stock ROMs many times and only now I'm having this problem, so, I think it's related to that format all + download in some way. Do you know if it can be the cause of my problem and how to fix it? My phone is umidigi power (mt6765)
Thanks

Basically when I use format all, it also deletes a device-specific identifier regarding trusted execution environment or something like that, which results in a fingerprint loss and other problems like mine. On logcat i noticed a "trust service" crash which makes sense. Luckily umidigi offers a fix for that, even though I had to pay them $15. I will let you know if it fixes my problems when I get the fix(29-01-2020, 06:20 PM)steel71 Hi, yesterday I accidentally reflashed stock rom with format all + download in sp flash tool.

do you remember the original build number of your device?
atm, when you flash stock firmware, does the device go through initial setup or does it boot straight back into homescreen?
