Hi all!
I done the re-partition, and the low-level format in the disk-tool, but nothing changed (i tried with fat, and fat32 too). I also tried an other firmware, and extract-repair the firmware with sfwx but the problem exist...
I'm suspicious, that it's maybe a hardware problem, so now i make a try to re-solder the battery cables, and check for other faults in the electronic.
I will tell what happend! :roll:
