Topic: Problem "upgrading" TP-LINK MR-3220 to OpenWRT using www
I just got an MR3220, (it is not paid yet, so I can't disassemble it to solder serial...),
I want to flash OpenWRT to it.
I have read that I have to use trunk, so downloaded an image (bin).
Now if I want to flash it from TP-LINK www, IF filename is openwrt*, www refuses to start upgrade.
IF I change NAME to some existing TP-LINK image, I can "start" upgrade ("Do you really...?"), but then I get:
"Error code: 18005
Upgrade unsuccessfully because the version of the upgraded file was incorrect. Please check the file name."
[I have even downgraded firmware to version from TP-LINK site dated 2011, but this does not help]
Sticker on the back says "Ver 1.2"
