Pretty much as in the title. I believe it was on the dualrecovery root for 5.1.1 and the latest supersu binary update just dropped it into a bootloop. What do I do now?

Yep I posted a workaround in the superSU thread a couple of days ago. Flashing the zip version from TWRP works and fixes the bootloop.

Did you try to start in recovery with your phone, run the TWRP file manager and plug your phone? Don't you get access to the phone file system?

Boot into TWRP recovery and install SuperSu 2.79 zip from ChainFire or his latest v2.82 linked below that supposedly fixes the issue with bootloop on Xperia devices.

I was able to solve the boot loop problem with your advice but now the SuperSU icon is disappeared :confused:

Any idea how to bring it back?

so I had the exact same problem......supersu asked for an update and that caused a boot loop on my Z1c

I reflashed supersu using recovery,
First v2.82 << that did NOT fix the boot loop
Then v2.79 << this fixed the boot loop.

However, I left the phone to charge for a few minutes and supersu auto updated. Now it says it is v2.82 inside the supersu app. The app still keeps nagging about an update.......which I am not installing, fearing it will cause the boot loop again ;)

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.
