[SuperSU] razes:
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 directly (without the Restore of TWRP backup initially) the Update_SuperSU 2.79 or 2.76 (originally I have version 2.76) with TWRP

Should I wipe cache, dalvik cache and data before and after the installation?

3. Flash with pre-rooted ROM with TWRP

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

It is important to me to keep the bootloader locked, because otherwise camera software become compromised in my Xperia Z3 compact.

I would appreciate for your suggestions. And yes I read that thread (part of it, not all 1226 pages) and forum but still have some questions. For instance, I confuse which version of the SuperSu I have to flash - the stable or the Beta version which I believe is SR3-2.79. Can I install the SuperSU (2.76 or 2.79) with locked bottloader (it is locked now)?

Xperia Z3 compact

Lollipop 5.1.1

Initially root was done with the Pre-rooted ROM.
