Need guide to update firmware and ecam on Gt-media v8uhd

I tried all the ways to restore the factory firmware, until I got the EZP023 programmer, I installed the factory firmware from the beginning with it, it's simple, I have ecam codes from the Chinese, they sent me 10-digit numbers, I need to make a bin file from it, I didn't succeed, when I try to install from usb it always says invalid file, can you help me...thanks

Now it's okay, I got it, I need ecam firmware and this code is entered in the cs folder, ecam option, there are no exyu channels, only pinks, tv total nothing, not tv max or any package from these areas, I paid 10 dollars for nothing, it opens some Polish ones and they gain, so no one buys this ecam, my recommendation - I tried to return the mars and it can't, I have to use the programmer again. I guess it will work, after all it is the best for this type of media, and the only reliable programmer is EZP2023 which I bought and it works great. Regards
