[Android Software/Hacking General [Developers Only]] :
Tried test 7 and it froze on first reboot. Second reboot it booted and none of the values appear in build.prop. I didn't get any errors during install.

Here's my build.prop in case I overlooked the values.

export PATH=/data/local/bin:$PATH
$ export PATH=/data/local/bin:$PATH
$ su
