Hi,

To made a terrible mistake today: Loaded a V1 firmware on a V2 TL-MR6400 ... (see below as to why this happened).
I still can access the router via LAN and WLAN, but I cannot upgrade the firmware and I cannot reset to factory defaults.

I currently have firmware 1.0.8 Build 150906 Rel.52604n loaded.

a.) upgrading the firmware always results in: "The connection was reset" right after I hit "yes" in the confirmation dialog.
b.) resetting to factory defaults always results in:

Error code: 20

Error occurred, please try again.

right after the confirmation.

So I'm stuck. I know that this is pretty dumb ... any ideas how I can rescue my TL-MR6400 ?? I already tried different browsers (Chrome, Firefox, IE) but no
avail. I also tried power cycling the box several times.

I'd appreciate any hints ...

Thanks a lot // Tom

P.S: Reason why this happened: The firmware download web page told me to double check that I have the right firmware for my router. And it also said I should check the country page --- so I checked the country page and it re-directed my to the Austrian local TP-LINK page where only this old firmware was available. So I thought this would be the right one ....
