Can someone please help. I have an HTC Hero and loaded a 3 UK Rom Android 1.5, from the web forums. I'm not sure if I used "update-hero-generic-2.73.771.73-signed.zip" or update-hero-generic -2.73.771.73-rooted-signed.zip. Does it matter? I now get the OTA update to android 2.1, but when I try to install, I get the following; Build : RA-hero-v1.5.2 Finding update package … Opening update package … Verifying update package … E:No signature (660 files) E:Verification failed Installation aborted. What am I doing wrong? I'm really very new to all this. Thank you.
