DVR DS-7204HUHI-F1/N upgrade firmware more than 32Mb is wrong.

[_Strannik_]

I can not reflash the DS-7204HUHI-F1 / N
there was firmware V3.4.80build 161028 multilanguage.
I tried to reflash it with regular tftp but I always got an error Open file [C: \ tftp \ econt_Vision-AV2000] failure

I tried to flash through TTL USB via PUTYY firmware more than 32Mb is not flashed (all new firmware on the site is more than 40 MB)
log with Putty:
timeout for link [4999]!

What do you advise?

For this method, use a standard tftp server that does not have a 32MB size limit, such as this : TFTPD32 : an opensource IPv6 ready TFTP server/service for windows : TFTP server
