I’m not adverse to cycling the power. I did exactly as you say and get to the password screen. Whatever i put in for a password does not work. That’s why i thought i might have done something wrong
It sounds like the hack didn't install. When you ran it, the first thing it should do is present the message PRESS ANY KEY TO START OR TURN OFF IGNITION TO ABORT. What is supposed to happen is you should press one of the hardware buttons like Vol - or +, or <. >. If you turn off the ignition then it won't install the hack. At that time, you can't re-run the hack script without rebuilding the SD from the zipped files. TestMode.key is deleted from the SD to prevent accidentally rerunning.
So, it isn't clear to me if you ever got past the above message. If you decide re-try the script, I recommend using a different SD because it saves the original RenewalIFLib.dll files (from PRG0 and PRG1) on the SD. To be 100% safe, you should keep the backed-up files.
However, if it sensed a keypress you should see a message Installation will start in 5 seconds... and then BACKING-UP EXISTING RenewalIFLib.dll FILES. Do you remember seeing such messages? I'm trying to get an idea if the script even ran.
