H120 after upgrade rockbox question

[darksome]

Hi all,

I'm completed install Transend 4GB CF card into H120, but when I finished install rockbox firmware, rockbox is prompted me to restart mp3 and load the "upgrade firmware" function on H120.

But when I tried to load "upgrade firmware" function, it is only return to the selection menu, it doesn't execute this function, so please tell us how to sorting this problem.

P.S. I had format the CF card to FAT32.

Thank you
