[HTC ONE] Unroot then root "security warning"
After few months with my HTC One rooted and unlocked (running the Google developer edition 4.3), I wanted to unroot my phone (especially to use Barclay's app which doesn't work if the phone is rooted).
after a "fastboot oem lock
", I have an "***Security warning ***
" at boot. I know that I have to install everything using a RUU file, but when I try to, I've got another error message which say something like "can't install, hboot older
Tried everything since few days and can't make it work. Any idea would be appreciated!
