first of all download an application called visionary+
make sure that the usb debugging is turned on.
i hope you know how to create a gold card and that you have done it.
put the gold card in the phone.
then instead of running the crackin.bat file open it in word pad.
then temp root the phone using visionary+
type in each command one by one in the command prompt.
then when you reach the step where they show "adb shell" followed by commands.
then you will get a '$' symbol
then type su
then you will get a '#' symbol
then continue typing the commands without the 'adb shell'
after you type 'reboot' ignore the 'wait_for_device'
once the phone is back on temp root it again before you proceed.
finish the procedure this way.
Remember that you will get many error messages while you type each command. ignore the messages.
You wont get the full crwxrwxrwx. But what you get will be good enough.
now you can run the RUU
please reply if you have any doubts.
