Hi, CWM is ClockworkMod which is used when you want to Backup and Restore ROM or stock recovery.

I have updated both my U8800 X5 phones to the Official Huawei Android 2.3.5 version without any problems.
A Forum Post I read suggested that a 2GB Micro SD card should be used to apply the Download and it worked for me.
I would try to do a Factory Reset which should restore your phone as out of the box state.
To do this:
[FONT="]Huawei U8800 boot menu [/FONT]
[FONT="]To get the boot menu where you can among other things factory reset the Huawei U8800, do the following. If your phone still has the “old” 2.1 or 2.2 versions of Android, just power off and then restart. If, on the other hand, you have 2.3 (Gingerbread), you may have to power off the phone, slide off the back cover, take out the battery, wait a few seconds, reassemble and then do the following:[/FONT]
[FONT="]Press and hold the [/FONT]
[FONT="]Volume up+Power[/FONT][FONT="]
keys and keep holding them until your phone vibrates. After a few seconds, you should get an exclamation point inside a triangle and a 3D android, followed by the boot menu. Now you can reset to factory default. You do this with the menu item [/FONT][FONT="]wipe data/factory reset[/FONT][FONT="].
Do NOT under any circumstances select wipe cache partition, as this will brick your phone unless you know exactly what you are doing![/FONT]
[FONT="]Interestingly, all menu items are all lower case, for some reason, with no initial capital letters. To select an option, arrow down with the volume buttons, and select using the power button.
Do check you have the correct option before doing this![/FONT]
[FONT="]As usual, I accept no responsibility when providing this info.[/FONT]
[FONT="]Always make sure your phone battery is fully charged before carrying out any of the above. Neil.
