Pete - the FRG83G OTA file here, is there a reason it won't flash through stock recovery? It gives a signature verification error every time. I would think if it was the official OTA file, it would flash through stock recovery - since that's what the actual OTA file will do. I'm trying to update my "back to stock w/o rsd lite" tutorial here, and having a true Master FRG83G OTA file that can be flashed on all three major recoveries is key (like we had with FRG22D). Thanks for any input.
