I also as many other users here have updated the library of super Su (got the
notification). And after the installation and rebooting got into the booting loop.
I have wiped cache and dalvick cashe with TWRP but it didn't help. I installed the
2.82 Update-SuperSu via TWRP. And after the long time of apps optimization I was
able to boot into the Android (Lollipop 5.1). However, I found the root was lost.
The RootChecker saying: "Root access is not properly installed on this device".
So, basically my question is how to restore the root and keep the bootloader locked
(important!)
Here I see several scenarios:
1. Restore using TWRP backup.
Should I wipe cache, dalvik cache and data before and after the restore?
2. install Update_SuperSU 2.79 or 2.76 (originally I have version 2.76)
Should I wipe cache, dalvik cache and data before and after the installation?
3. Flash with pre-rooted ROM.
Should I wipe cache, dalvik cache and data before and after the installation?
4. Start from zero, i.e to follow the procedure I have rooted the phone at time
I've purchased it. Namely:
4.1 Downgrade to KitKat
4.2 Root with FlashTool.
4.3 Flash prerooted Lollipop rom with TWRP
4.4 Flash with customized Lollipop rom
Xperia Z3c (compact)
Lollipop 5.1.1
I would appreciate for your suggestions.
