Hi s1fw
I tried the firmware you gave me but no results

I even tried it with different versions of firmware upgrade tool and here are the messages that i got:
MP3 Player Upgrade Tool 4.00:

I opened the firmware with
FirmwareModify tool, and changed the battery type from :
1.5 alkaline battery to
3.6 Li-polymer battery - but nothing changes, i got the same messages
Can you please advise me something else... Please...
Thank you very much for you support.
