Justop MPA040BKT

= Identification = This was sold in two versions with the main difference being the functionality of the remote IR controller. Very similar to Miniand Hackberry (1GB RAM version) and the images for the Hackberry work on this unit as well. Supplied with Android 4.0 that could be updated with various versions released by Justop (by the administrator Justin) on their old forums with the latest being "JUSTOP_A054_V1.8.1_20130809_ytb_fix_old_remote" or "new remote", depending on the hardware version). The forums are active again on https://www.tapatalk.com/groups/justop/ (as of July 2020) but all the old messages are gone.

FEL mode
