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?
