CyanogenMod 10.1 has been spreading like wildfire across the XDA forums, mainly in the form of unofficial ROMs. The latest device to receive a CM10.1 ROM is the Motorola Droid RAZR.
XDA Recognized Developer Hashcode put together what is currently an alpha release of CyanogenMod 10.1. The staple functions of device, phone, data, and WiFi are all functional, but the list of non working features is significantly longer:
BUG: gapps/stock browser FC due to thumbnail / db issue
GPS will stay on “searching for signal”
No camera for now
No HD codecs for now
No hwcomposer yet for enhanced composition (wifi display, gpu enhanced overlays for battery savings)
No wifi tether yet
So if you’re looking for something stable for use as a daily driver, this ROM isn’t for you quite yet.
The ROM is available for both the CDMA and GSM variants of the Droid RAZR. If you want to give it a try, check out the ROM thread.
