i got a little problem with my h340 which is allready running with rockbox. i cant remember what happened, but while playing something it jumped into some debug mode and drained the battery. (at least it says its at 0% although it can run anyway). but ever since that, the navigation keys dont really work anymore. i cant use the down or up key. and when i want to load the original iriver firmware, it tries to start it, but nothing happens. i did reinstall both the bootloder and rockboc, but it didnt work. is it broken, or do i have some hope? What do you mean by "some debug mode"? A panic screen? idont know what a panic screen looks like. it said something like "debugging now" and something came up the screen * GeekSh4dow ist jetzt bekannt als GeekShadow This happened by itself? i really cant remember that i did something out the normal stuff I'd guess you got a panic, although then I don't understand this "debugging now" bit fuck me. i just started the damn thing and it works again.... i booted it like 20 times and the keys didnt work. now all of the sudden it has chosen to work again.... Maybe it didn't really have enough charge before? i havent it charged in that time and the battery indicator is at 70% now as it has been before the "blackout" and i ordered an ipod tody... I don't know then. Maybe a coincidence? Some dirt in the buttons that now went away? after that i disassembled it and cleaned every part with pressure air. dont know what went wrong. but the iriver firmware should have loaded which it does know Actually, if some buttons have bad contacts, they might report presses all the time, which might interfere with booting but if they report contact all the time, and i boot rockbox than shouldnt they navigate all the time, or do somthing else? that was not the case. they just did not work, respectively did the wrong thing That depends. If more than one button is stuck, probably nothing at all will work Other things may happen too, depending on how buttons are connected ok. i guess i have to live with that mystery and the fact that i bought an ipod If it works now, I wouldn't worry about it dont have a choice anyway. but thanks for your help!
