Do you have correct structure of files on root of your usb.
It has to be same as other firmware.
Check last firmware and compare what you got on your pendrive.

I have checked folder structure on my usb drive and its ok ... exactly the same as 2900 firmware. I also foramat my usb to fat32 but it didnt help.
i would like to change firmware because my TV is working reallly slow and there is huge lag or no repsond when operating with remote controler, that may be some hardware issue but first i would like to check if thats not firmware malfunction, but so far no luck :)...

The "image" folder shall be in the root of the usb drive. I dont really understand why somebody already hasnt published this, OBVIOUSLY, important information. Since most of the RAR/ZIP tools just create one more folder named as the zip file itself and thats where the problem starts. Good luck!
