I'm following these directions: [Mac Procedure]: How to Root the HTC Thunderbolt - Android Forums I got past the bootloader step and tried to install PG05IMG.zip. When I type the terminal command ./adb devices I get the error -bash: ./adb: No such file or directory. Now I'm stuck in the middle. I have the downgraded PG501IMG. What have I done to my phone? What can I do from here? Is it safe to power phone on and off? I really need access to use my TB as a phone this weekend. This is quite disturbing as I don't want to brick my phone. All help greatly appreciated.
