I have already downloaded this file, but it seems that there is an error in my file. The navigator is not flashed with it. My firmware is 4.50, HWID 3725, but the firmware does not start. I flashed it via WebUpdater, and tried to place the file in the folder manually

Second question, please tell me.
Is it possible to patch ECHOMAP UHD2? I read that it is supposedly impossible

That's what I've read too. I don't know any more about Marine devices than you do.
