Hello, the solution was to install it directly without firstly copying to flash. It seems like issue of version 10.5.0.4 because other versions worked properly. I tested a few of them. Like I said, i used 7zip and USB was FAT32. TFTP behaved the same way in version 10.5.0.4. Thank you for your help. Kind Regard, Martin
