CM10 for RAZR HD XT925 - 2012-11-25 - xda-developers


This is a CM10 (Jelly Bean, Android 4.1.2) firmware for Atrix. It's not a official CyanogenMod, and it's not supported by CM team.

I'm not responsible by phone bricks of any kind, or any other damage this firmware may cause to you, to your phone or any accessories conected to your phone.

For now I only have how to test the XT925. I think this version will have problems with mobile data on XT926 dev edition (if it boots, dont know), because some patches not included in CM are needed to make it work, dhacker29 is working on the CDMA patches.

Remember, this firmware has a custom kernel, and requires a unlocked bootloader.

Download links and information about what is working can be found on the website:
http://www.linuxmobile.org/razrhd

Instructions:
Download the zip (cm-10-*-UNOFFICIAL-epinter-xt925.zip) and copy to your sdcard.
Boot into recovery.
Backup your firmware and data!
Install the firmware (install zip from...).
Install gapps (install zip from...).
Wipe data/cache.
Reboot.

Thanks dhacker29 for collaboration.
