Hello,
I just bought them as second hand, sound is good, BT worked, but now BT is "blocked" slow flashing with no way to pair.
I tried "Reset" by switching them on, without power plug and it make them "restart" to one BT pair Ok.
I tried to upgrade firmware with a 8Gb FAT32 formatted USB key, with the right .hex file on it but nothing happend, USB key won't even light up.
So as asked before, is there a way to identify actual firmware version ?
If firmware upgrade finally work, will my remote still work ?
