CyanogenMod 10 (CM10) for Motorola Droid Razr HD Developer Edition (XT926)

Advertisement

Motorola might have disappointed a few folks by not releasing the RAZR HD with Android 4.1 Jelly Bean out of the box, but that’s okay, because at least on the Developer Edition of the device with an unlocked bootloader, you can try out Android 4.1 via CyanogenMod 10 (CM10).

CM10 is a custom ROM that provides a pure unadulterated Android experience, bereft of bloatware or custom skins. It also features a lot of customization options that allow one to personalize it for themselves, including a theme engine with a countless fan-made themes available for changing the look of the icons and interface.

However, as of November 6th, the ROM is in an alpha stage/early stages of development, so it may have some bugs and some things might not work properly. Things will improve as development goes on, but for now, it might not be stable enough for every day use. Also, this ROM is only for the Developer Edition RAZR HD on Verizon.

Let’s take a look at how CM10 can be installed on the Motorola/Verizon RAZR HD Developer Edition.

Compatibility

This guide is applicable only for the Motorola RAZR HD Developer Edition for Verizon, model number XT926. Do not try this on the non-Verizon RAZR HD or on any other device.

    NOTE: Don’t forget to at least note down your network’s APN settings, which are required to make mobile data work. Go into Settings » More » Mobile Networks, click on the APN that is in use, then note down the setting for each field. While APN settings should be automatically restored from network, you can enter them manually if needed to make mobile data work. You can also find your APN details → here.
