[AT&T, Rogers HTC One X, Telstra One XL] erasen1:
the phone is connected, there was an adb instance in another terminal thats why you see script starts adb-mac at the top.

I tried some commands in the script it looks the update changed file permissions

$ adb push su /data/local/su
failed to copy 'su' to '/data/local/su': Permission denied
$ adb shell
1|shell@android:/ $ mv /data/local/tmp /data/local/tmp.bak
failed on '/data/local/tmp' - Permission denied

someone on stock 1.81 can compare
