[Q] need some help installing custom recovery on already rooted device
i have a k2_ul device, rooted, 2.00 hboot, locked, S-OFF. i rooted it via moonshine last year and later upgraded to android 4.2.2. i never installed a custom recovery but want to install TWRP now.
when i wanted to install TWRP via fastboot i got
FAILED (remote: not allowed)
i suspect this ti because my device is LOCKED (i think that it was unlocked after moonshine but got locked when upgrading to 4.2.2, but not sure).
would need some help here. how can i unlock my device again? can i do it without htc.dev and without deleting all user data.
i searched threads in general section but couldn't find my answers, i appologise if i overlooked something.
ps - also, is my hboot 2.00 ok for the latest TWRP?
