Need help for iPode shuffle SigmaTel

[senoslama]

Hello.
I need help to find firmware for iPode shuffle SigmaTel STMP3500 512Mb. This is exactly iPOD shuffle 2nd generation clip clone. It does not have any LED display.
The problem is that It works only as mass storage device. I suppose that it's firmware has been damaged. I have discovered out some firmware in NET with corresponding set of upload software. So I recognized, that my MP3 player have version of the firmware 002.611.300. In detail info I see:
Boot manager – missing /i.e. 000.000.000/
USB mass storage – 002.611.101
Player – 002.611.300
Resource – 002.611.300

All firmware set I have discovered are older than my, or consist of different set of files / for example there is no usbmsc.sb/.

Please send the link of proper firmware for this MP3 player to download .

Thanks in advance.
