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
writing 'recovery'... FAILED (remote: not allowed)
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?
