I recently installed UltraJack Recovery to my T-Mobile Comet/ U8150 and installed a custom rom. This went fine and works okay. I then wanted to return to the original factory rom and found my backup was corrupted. I found a copy of the rom at another site after much looking but now it won't install. I get a "E:No signature (6 files)" and a "E:Verification failed", then "Installation aborted.". I searched for these errors on the internet and found that it is a common problem that some have used Clockworkmod Recovery to fix but the version of CWM on the Google Play store isn't compatible with the Huawei U8150. I have found a earlier version but it requires Fastboot to install and I havent been able to figure this out. If ANYONE can help me I would really appreciate it. I will try to help others on here when I can and I hope others will do the same for me. Thanks for any help folks!
