Topic: Going back to original TP-Link mr3420 firmware.
I have a TP-LInk mr 3420 router and recently I've upgraded the firmware from the original TP-Link to clean version OpenWRT. The reason I did that was that I've got a huawei e353u-2 modem which didn't want work properly with the router. I have to admit that I'm new to OpenWRT so probably I am confused about how it works.
Anyway, now I can't download drivers or firmware into the router because it doesn't recognize the modem. (I do not have any other connection with internet than 3g network).
My question is: can I go back to the TP-Link firmware by installing it from my computer drive using a LAN connection? What program do you recommend I use? (I have been using Putty)
Thank you in advance for any help.
