I have a root Nexus one, that at one point ran a custom ROM, but now has the stock Android 2.2 release. I just got an update to 2.2.1, and it fails with:
Build : RA-nexus-v1.5.3 Finding update package... Opening update package... Verifying update package... E:No signature (188 files) E:Verification failed Installation aborted.
What is the problem? Why does it say 1.5.3 in the build?
