How to Install Cyanogenmod 9 (CM9) on HTC Amaze 4G


Cyanogenmod 9 (CM9), based on Ice Cream Sandwich Android 4.0, is the custom ROM that everyone wishes they had on their phone. With the customization possibilities and performance enhancements Cyanogenmod ROMs are known for, it’s always good news when a device gets a CM ROM. The lucky fella this time around is the HTC Amaze 4G. XDA Recognized Developer sportsstar89 has released a development/work in progress version of CM9 for the Amaze 4G, something a lot of Amaze owners have been waiting for.

There are some major issues in the ROM though, like GSM calls and Wi-Fi not working (full list under the ROM Info section), which is to be expected as the ROM is a work in progress and in its early stages. Call it a preview version if you will. But it’s a start, as CM9 for the Amaze 4G has been a long time coming, and now users have a chance to try it out.

Let’s take at a look at how you can install CM9 on your HTC Amaze 4G.


This ROM and the guide below are compatible only and only with the HTC Amaze 4G. It’s not compatible with any other device. Check your device model in Settings » About phone.
