Attempt to root. 290 firmware
Ok guys here's what i did to try and root the new firmware. First I backed up my TA partion then flash a 4.3 ftf, unlocked BL to install a custom kernel to have recovery, flashed supersu.zip using recovery then flashed stock. 290 kernel using flashtool. After that i restored my ta partition to relock it.
Supersu was installed and its working on titanium backup and other apps that requires root the only problem is it doesnt work on root explorer or any file manager that needs root, cant move files to system. On root explorer i cant change rw to ro.
I also tried installing recoveries for unlocked bl and it doesnt install the recoveries, tried to manually install busybox and its not installing.
Anyone can help me on this? Phone is SEMI ROOTED. LOL! Reason why im doing this is because of the Z1 white balance port. It works well on 4.2.2
