Despite being somewhat abandoned by Motorola as far as official updates are concerned, the Motorola Defy & Defy+ are refusing to accept that the latest versions of Android are out of the question. Having recently received an unofficial version of CM10 based on Android 4.1.2 thanks to XDA Recognized Developer Quarx, these devices continue to defiantly (see what I did there?) push the limits of what they are capable of.
As you might expect, this build is still in quite an early stage. There might be bugs, and it may not be suitable for use as a daily driver quite yet. However this ROM does support the “2nd boot” capability of the Defy which means you can install it as your secondary ROM. That said, the general feedback within the development thread seems to be very good, without any deal breaking issues being reported so far. The build includes its own custom kernel, the (love it or hate it) CRT screen off animation, and a patch for the flashlight function.
Zips are flashable via recovery of choice as you might expect, but be warned that installing as a secondary ROM may take considerably longer than usual. Remember to choose the correct version, as there are different zips for the Defy & Defy+. So if you’re itching for the latest and greatest on your Defy/Defy+ then check out the development thread for more info.
