Upgrading DSR-250 A2 from A2 2.11 RU up to 3.12 RU
« on: November 12, 2018, 10:32:21 AM »

I've got DSR-250 HW A2 with the 2.11 RU firmware installed on it and I am trying to upgrade it to 3.12 RU.

According to the Release Notes I should first upload DSR-250_A2_A3_A4_FW3.11B202E_RU ("Intermediate") and then DSR-250_Ax_FW3.12_RU ("Common").

However here is how it's reacting to DSR-250_A2_A3_A4_FW3.11B202E_RU (got it from https://tsd.dlink.com.tw): http://forum.dlink.ru/download/file.php?id=10475&mode=view

And this is the even funnier error message when trying to upgrade from a USB stick: http://forum.dlink.ru/download/file.php?id=10480&mode=view

Any information here work?

Does using a browser and using the routers web page to update the FW work at all?
What browser are you using? Try IE11x32 or FF browsers.
