The Motorola Atrix 4g has been able to stay pretty recent with development, already having a couple of CyanogenMod7 ports and updated ROMs with the stock firmware.
To help keep up with the latest and greatest, XDA Senior Member jokersax11 has brought a port of CyanogenMod9 for those carrying the Atrix 4g. The ROM is pretty stable, with only a few things missing from being perfect. Here’s a list of things that aren’t working:
Adobe flash issues- either adobes fault or 2d issues fault
Car dock-missing apk
Some 2d issues, mostly works
Built in video playback- use 3rd party for now as its driver related
The list of things that are working is much longer and these problems aren’t the worst out there so people who would like to run this as a daily driver could do so if they can look passed the issues. Also, based on the updates, it appears as though jokersax11 will be sticking with it til everything is working perfectly so for those who aren’t ready to flash this yet, keep an eye out on the original thread for updates, download links and additional information._________
