[Q] bootloop by wrong permissions
I'm trying to unbrick a xperia l.
The XL is bricked because I changed the permissions over /system and /system/app folders (I presume).
The XL is in ASR<3e> everytime i switch on the phone, but unfortunately when choosing option 3 at the first command "adb install" I get an error "- exec '/system/bin/sh' failed: No such file or directory (2) -".
Data/Factory reset also done and cache partition cleared ...But no effect.
The phone is stucked in a loop: Error detected, Recovery/cleaning process is ok, apps deleted, press power to reboot and loop.
Last info: before bricking I was running the 4.3 GB
Please could someone kindly suggest a solution? Many thanks in advance.
ALSO USB DEBUGGING ALSO TURNED OFF BEFORE IT HAPPENED.
