HTC One is HTC’s flagship device. It was launched a few weeks ago. It’s bootloader has been unlocked, root access has been gained and also custom recovery is available for this phone. So now an individual can easily flash a custom ROM on the HTC One.
PACman is an excellent ROM. It combines the features of the Paranoid Android, AOKP and the CM ROMs. This ROM is available for the HTC One. However it has some bugs – LTE, in-call audio headphones/headsets, bluetooth, camera and the IR sensor are not fully working.
