Some people like skinned Android with Sense, Touchwiz, UX, Motoblur, etc, but other prefer stock. If you prefer stock Android and have a Motorola Droid RAZR M, I have good news for you! XDA-member dhacker29 released unofficial CM10 build for the RAZR M. According to the post it’s in beta, and most of the main features work except for WiFi direct and NFC. There may be other things broken, but the developer hasn’t found anything else yet.
You can get the ROM from here.
