YouTube - How To Upgrade Huawei Ascend 2.1 To 2.2 Tut So i found this tutorial and followed it and it was successful for me, and now i have android 2.2! But then i read from somewhere else that says -----> " You will get a NO UIM CARD error is you re-download titanium backup, please dont open clockwork, titanium backup or z4root once froyo is installed. IT WILL BRICK YOUR PHONE. However there IS a fix. If you get the error, msg me and I will give you a link to reverse it." Is it true i can not re-install titanium backup nor z4root?
