alright, so i'm following this supposedly dummy proof guide and i'm still having issues. my tech level is somewhat high so i'm no **** nugget when it comes to these things. i'm on step 32 here http://androidforums.com/all-things-root-evo-4g/99793-tutorial-idiot-proof-root-guide.html i cannot get the update.zip to work. when getting to the recovery screen, i see the following "E:Can't open /cache/recovery/command" ignoring that and clicking "apply sdcard:update.zip" i then get the following "-- Instal from sdcard... Finding update package... Opening update package... Verifying update package... E:signature verification failed Installation aborted." does anyone know what is going on and can possibly help me out? thank you!
