XDA developers have gotten one step closer to porting our favorite custom ROMs, like Cyanogen Mod, to the Motorola Atrix 4G. Using this program they are able to load scripts before the Android OS starts which can allow for custom ROMs to be installed on it. Although a large amount of developers have slowly stopped messing with the Atrix due to the locked bootloader, hopefully this will restore some faith in the modding community and bring our favorite mods and tweaks to the Tegra2 phone. The 2nd Init scripts are ported from the Motorola Defy which has had CyanogenMOD running on it for some time now, so hopefully this will open a door for a large amount of possibilities. As of right now there are a few Gingerbread ROMs that are available for the Atrix, but not many. The stock OS that comes with the Atrix, and the Droid X2, doesn’t seem fully optimized for the device so tweaking by XDA and other web developers can make these phones well worth their dollar.
