I'm attempting to root my phone and have placed an update.zip in the root of my SDCard. I get the message that the zip is not signed and the update fails.

I understand that VZN started added this checksum to make sure that only official OTA's can get installed. Does anyone know howto get past this so that I can root my phone, so that I can install cyanogenMod, so that I can do wifi hotspot tethering?

You may have a bad file, either from a bad source or it just got corrupted. I would try again. Follow this tutorial on DroidForums.net. It reportedly works fine with FRG83D.

I downloaded twice and got the same result. Thanks for the link to the thread. I don't know how I missed that one on DroidForums.net –  It Grunt Dec 30 '10 at 3:58
