Thanks for the advice. I have not flashed for a long time so i am a little unsure. Is this the right procedure?
1. Backup!
2. Flash FTF file with flash tool
3. After boot, install Dual Recovery via official installer (via PC)
3. Boot to recovery and do a full wipe.
4. Flash this rom + update.
Is that right? Is the internal sd erased when i flash a ftf?
For locked BL? yes.
Though, im not sure if u can root on .222 LB for getting recovery installed because I'm already 2,5 years unlocked lol.
For UB:
-just flash full ftf
-let it boot
-reboot to bootloader
-flash zombie kernel via fastboot
-boot to recovery by tapping screen when orange led comes up
-flash this rom
-let it boot (you will run stock kernel now and have xzdualrecovery installed on existenz)
-reboot to recovery
-flash zombie kernel again
-flash xzdualrecovery removal tool zip (it won't play nice at bootup, having three Recovery's)
-reboot
BTW , coming from .222 u don't need to fullwipe, cache is enough.
Yes, a full ftf (means flashing everything except for TA) including userdata.sin will wipe everything stored on the internal SD.
Just for sure, remove the external SD.. U never know what can happen lol
