How to Bypass Android No Signature, Verification Failed Error
By Ben Johnson last updated February 7, 2012

Share on TwitterShare on Google+Share on FacebookShare on LinkedInYesterday i received Android 2.2.1 (FRG83) update (signed-passion-FRG83-from-FRF91.c8847c98.zip) on my Nexus One OTA. Before applying the update, my Nexus One was running Android 2.2 (FRF91) which was rooted using 1-click Universal Androot utility. Only applying the update via stock Android system recovery, i got “No Signature, Verification Failed Error” error.

After installing Amon_Ra’s Recovery image and downloading the (FRG83) update manually, i tried to install the update.zip via Amon_Ra’s Recovery but unfortunately again got the same “No Signature, Verification Failed Error” error.
