When in Berlin, we had a sweet hands-on with the Red and Blue versions of the HTC One; but we’re not talking about colors here. While going through the menus we have noticed Android 4.3 powering the devices at HTC’s booth. Surely there have been a couple of leaks and custom ROMs based on Google’s latest, but this time, we’re looking at an AT&T specific firmware.
Apparently it is available to download from the source link below and it will only work on Ma Bell’s network-branded HTC One devices. We’re looking at Build 3.10.502.2 but, as always, whenever tinkering with your device and non-official ROMs, make sure to have a back-up handy, read the instructions, and understand the risks!
