Cyanogen release a new version of his mod, that is legal. It features the latest Donut release. Check it out here. I didn’t have Cyanogen’s Recovery Image, so installing this version was not very easy. 4.1999 won’t install without Cyanogen’s Recovery Image. I always got an “Installation aborted”.
- Get the cm-recovery-1.4.img from here
- Get fastboot tool from here and follow the instructions below the downloads:
On OS X and Linux, you can store the fastboot executable anywhere on your machine. On Windows, you must store the fastboot executable where it can find the AdbWinApi.dll file (included with the Android SDK), otherwise it will not work properly. The recommended place to store the fastboot executable on Windows is with the other tools in the Android SDK, in the <sdk>/tools directory. On all platforms, you may want to add the location to your PATH, for convenience.
USB Driver
If your development machine is running Windows, you should make sure to update your USB driver before continuing. For your convenience, the Android SDK (1.0 r2 or later) includes an updated USB driver that you can install. For more information, see Setting up a Device for Development on the Android Developers Site.
- Get the device in fastboot mode:
To enter fastboot mode, power up the device (or reboot it) while holding down the BACK key. Hold the BACK key down until the bootloader screen is visible and shows “FASTBOOT”. The device is now in fastboot mode and is ready to receive fastboot commands. If you want to exit fastboot mode at this point, you can hold down the keys MENU+SEND+END (on the Android Dev Phone, SEND is the “Call” key and END is the “End call” key).
