Full conversion of the HTC One here, bootloader unlocked, S-Off, RUU'd to the GPE full conversion. Did have TWRP as a custom recovery, the conversion wiped that. Udpated to 4.4 now that sucks. Took forever to get a custom recovery on then it was only CWM that would install and couldn't get superuser on. Finally got the TWRP and still can't get superuser to work. So Root Checker says its not rooted. Battery life is good, the dialer sucks as the contacts are different and separate. The google search bar is annoying and constant , can't get rid of it on any screen that I can find. There are some nice little tweaks in the system that might interest some , not me. So, I think I am going back to a custom rom like Elegancia if it works now on this Hboot and set up., if not RUU ing to factory again as a HTC One. From what I have played with I am not a big fan of Kit Kat.
