Linksys E1200 firmware upgrade - impossibru?

Question

Linksys

I bought myself a Linksys e1200 a month ago. I'm trying to reflash here and nothing at all. There is some kind of incomprehensible firmware from 2013 version 2.3, when the last one from the office. site from Linksys 2.0.7. When you try to flash it, it reaches 10% and gives an error. I reflash naturally through the cable. The router is new. Reset and hard reset did. Someone faced such a problem? I wrote to Linux, spoke with support for about 2 hours - so they didn’t advise anything normally. Maybe someone faced a similar problem? Can I force a firmware update somehow?
