I was once formatted player and after this, player only displays: Nand flash no files. And returns to general menu. What i could to do to solve this problem? I understand that i was deleted some files and therefore player do not understand music files on it. I tried copy these files from same player only with 2Gb built in memory- it did not help... :(
When i click on the firmware version, player displays: by mengWP driver:1697
Maybe somebody can help me, please?
Thanks in advance!

I am sorry if i have mistakes in my english, but i hope you understand me... :oops:

Still actual...
