Hi, i recently down grade my C6903 to 534 and successfully root (thx to XDA), when i try to update the 257 and it's gone. they change to 290 now and i dont want it since it will lose the right of root. Is there any method update to 257 beside flashtool?
if i use flashtool update to 257, will i still have my apps and personal stuff after update? because when i down grade to 534, flashtool wipe out everything in my phone even i make sure i didnt mark wipe out my stuff (and i didnt update at that moment). so i dont want to re-install my stuff again.
if i use flashtool update to 257, will the right of root still exist?
Please advice me how to get 257 update with most less effort (as long as i can keep my apps and personal stuff).
If your phone's bootloader is unlock-able, then you can back TA partition, unlock bootloader, install recovery, flash Supersu.zip, flash kernel from FTF (Don't wipe anything, exclude everything but kernel), then restore TA partition from your backup.
This way you will have a fully rooted Xperia Z1 Android 4.2 14.1.G.2.257
