Install new firmware with OTA option on Android cell phones

To accomplish this we will install a customized, aftermarket firmware distribution named CyanogenMod.  This guide is optimized for the HTC Magic provided by A1/Vodafone in Austria. If you have another Android device you will have to choose accordant images. Download a recovery image from your favorite Android site or from the following resource and put it on your sd-card: http://n0rp.chemlab.org/android/Also download the HTC factory system image ( http://developer.htc.com/adp.html ) and the latest Cyanogen's ROM ( http://www.cyanogenmod.com/ ) and copy it into the root directory of your sd-card too. Start a terminal emulator on your rooted Android Phone and cd to /sdcard. The following command flashes the new recovery image:sudo flash-recovery cm-recovery-1.4.img You can start into recovery mode by holding down the home key on your device while rebooting. Before wiping all data a backup is recommended by selecting 'nandroid backup' from the recovery menu. After wiping apply the HTC factory system image and finally the latest ROM from cyanogen. The first boot of the new ROM will take longer than usual - just be patient - you can explore the new feature in some minutes.Be sure to install the CM-Updater to receive notifications for new updates and be able to download and apply them immediately.
