i started with a stock N1 running unrooted froyo, then i unlocked the bootloader using the command "fastboot-windows oem unlock". i know that it is in fact unlocked because i see the open lock icon when the phone starts up now and i also see the **UNLOCKED** text in the bootloader menu. now i'm trying to use cyanogen's quick rooter (stock kernel) from here: Quick rooter for stock FroYo systems + 2.6.34 kernel - xda-developers. renamed it to update.zip (made sure it's not update.zip.zip), copied it to sdcard and i'm flashing it the same way i did the froyo update from the recovery menu but i'm getting an error saying signature verification failed. why would i still be getting this message after unlocking the bootloader?
