Let me first say that I have spent nearly 2 weeks searching for a resolution to this problem and have read countless threads but none were able to help. I am Running an HTC Incredible S Android version : 2.2 Baseband version (Radio): 2.15.10.07.07 HBOOT- 0.92.0000 I am trying to replace my CWM Recovery 18.104.22.168 with this 4ext recovery so that I can Install Android Revolution 1.1.7 These are the methods I have tried. 1) Terminal Emulator I placed new recovery in root of my sdcard and renamed "recovery.img" open terminal type su (got root) type flash_image recovery /sdcard/recovery.img then I receive error "error writting recovery: No space left on device I tried a different version of a 4ext recovery and still received the same error. I tried formatted SD Card to FAT32 = same error Tried formatting internal memory = same error. 2) CMD Prompt through Windows PC I have the SDK kit installed with ADB Enable debug mode and plug phone in Placed new recovery in c:/ root Open cmd prompt on PC type cd C:\android-sdk-windows\platform-tools type adb shell type su type flash_image recovery /sdcard/recovery.img receive error "error writing recovery.

Make sure to change the name of the original cwm recovery. Open rom manager and select flash. Please help me install a 4ext recovery. I am going insane because I feel like I have tried everything.
