First, ROM Manager does NOT work on this phone. There are threads stating it does, but it doesn't. Next, your recovery isn't completely borked...you can still flash over it with these instructions: (ps-I did the same thing you did, and thought I would be returning my 2 day old phone for a new one...these steps prevented that...as always...backup yo' shiz son!) Also, these instructions DO assume you have a working SDK/ADB install on your computer.
Install PDAnet on your computer. This will install the USB drivers for your A2.
Next, look for the clockwork 184.108.40.206 M865 file...it's google'ble.
Next, extract it to a folder on your computer.
Navigate to the folder you extracted to and leave it open on your desktop.
Double click the 'adb-windows' (or 'adb-linux' etc...if you are using a linux box, 'adb-mac' if you are an iTard) This will pop a cmd window up and then it will disappear again.
Turn your phone off, then hold volume up and power together until it gets stuck at the white Huawei screen. Once at that screen, double click 'install-recovery-windows' (or linux or mac again...) and plug your phone in USB...it should do everything for you.
Some hourglasses and some window pops and then nothing...unplug your phone, pull the battery for 10 seconds and then reboot into recovery by holding vol down and pwr button. VIOLA! CWM!
