Hey. I have a F900 BT, which has stopped working. Its keeps starting over. Seems like the boot sector is screwed. nothing happens. Reset button does not work, Cant get in to service Mode. Test Mode is not working.

Anyone know what I can do

your reset button doesnt work?? Like its not registering your pushing it in? That sounds like hardware rather then software damage.

what happens if you try to download one of pioneers updates? will it try to update itself?
