[Xperia Z2 Q&A, Help & Troubleshooting] bjorn96:
I dont really know how to start.

SuperSU by [MENTION=631273]Chainfire[/MENTION] is a great app. But lately I have had a lot of problems with it. I somehow loose root, or have restricted root.

I cannot use Xposed, Xposed reports that the system is read only. When i try replace SuperSU with Superuser, the superuser says the system is -rwxr-xr-x, is this ok?

All this problem came after he updated to 2.37

I have also tried to flash a new 4.4.3 FW many times, I tried PRFCreator, all possible solutions without getting proper root.

I hope someone has the solution, because im really stuck now.

I know I ask a lot here ( :D ), but I try learn this and now I have no idea what to do next...

[MENTION=4895687]Envious_Data[/MENTION], will you be my savior?? :fingers-crossed:
