Try this:

It's the official full install for FRG22D (don't worry about the security certificate thing;it's Google's server; it always does that.
Manual install instructions :
1)rename downloaded file update.zip and move to directory /sdcard using a file manager (make sure you have file extensions showing; update.zip.zip won't work)
2) Turn your phone off.
3)Boot into recovery (Press Power then press X; when you seen the phone is turning on you can let go of Power but keep holding X)..
4) Wait for a triangle with exclamation point to appear and release X.
5) Press the volume up button and hold and quickly press the camera button and hold. Recovery console will appear.
6) Using the D-Pad select “apply update.zip” . Let the update proceed. When it's complete, use D-Pad to select reboot phone.
This will install the full FRG22D over the patched version. It often solves these problems. If it doesn't, check back with your results.
