For you root fanatics out there – you already know that the ZTE Score is not supported by ClockworkMod Recovery Images.
This remains true.
CricketUser forums, however, have some bright devs deticated to working on phones like the ZTE Score.
One such user has compiled a custom recovery image from source and has made it available on CricketUser forums.
This user reports that CM7 custom rom is in the works for the ZTE Score to go with the custom recovery image.
