i have Philips LCD 42PF9731D/10. I want to upgrade my firmware. I have tried with 3 different USB and it doesn't want to upgrade. I have try to format them on FAT and also on FAT32.
On USB there is only autorun.upg file and nothing more (there aren't any folders in USB)
I have read all instructions and it still don't want to upgrade.
What could be wrong?
