We aren't talking miracles or magic. Pretty hard to totally brick a STB if you are using a correct firmware build. An editor may soft brick (corrupting user data base), but with serial connection most can be restored. Save firmware as an .abs file to USB for back-up. This file could also be used for restoring via USB or serial. Just don't load firmware for another STB and don't install/overwrite the bootloader.
One version of Ali editor will work, but the user would need to determine what version is compatible. Trial and error using .abs file type.
I see a serial connection on the PCB. It doesn't have a connector installed, but easy to solder directly or use pogo posts. Attempt a read from this port to confirm pin config (no external power if you aren't sure) about reading the PCB traces and determine type of serial communication.
