Love my Xp Deus 2, but like a few other people, mine died after updating the firmware. After the firmware update, it showed “SUCCESSFUL” on screen, then shut down, and would not turn back on. Contacted the seller who gave me a direct email address to contact XP, which I did immediately. After a week of not hearing anything from XP I decided to repair it myself. Not happy that it came to this for such an expensive machine.
If you attempt this, ONLY use a plastic pry tool or plastic guitar pick.
Go slow and be careful as O-ring is coated in grease and can get on the inside of display screen!
Make sure the O-ring remains in place and lubricated during reassembly, otherwise the remote could leak if submerged.
Remove 4 screws on speaker cover and then remove speaker first, pay attention to speaker spring contact orientation for re-assembly.
Remove two screws on bottom front, remove single screw under serial # sticker. Bottom piece slides out easy enough with minimal prying. Gently slide board out, no need to remove data port nut as there is just enough slack in the wires to access the battery plug.
Unplug the two-wire jack from battery on the board (see green circle on attached picture). I waited 10 seconds then plugged back in and remote immediately booted up. Everything works fine, shuts down and turns on and operates normally. This method will also work if you have the reverse problem when the screen locks up and you do not want to wait for battery to run down.
