I recently bought TP-LINK Archer C20i router and attempted to install OpenWRT. Now when I connect my router to the laptop it is not getting connected. The lights on the router are blinking (turn on and off).The following is the procedure what I followedFound the OpenWRT wiki for my respective routerFrom there I downloaded Chaos Calmer 15.05.1 ramips-mt7620-ArcherC20i-squashfs-sysupgrade.binNow I connected my router to laptop and in browser URL typed 192.168.0.1 to open TP-LINK router settings.Entered admin username and passwordNow went in System Tools-> Firmware UpgradeSelected the downloaded file which is ending with sysupgrade.bin and pressed upgrade.Now the default gateway IP got changed from 192.168.0.1 to 192.168.3.1.But the weirdest thing is when I tried to connect to it with new default IP address from the browser, it is not getting connected.The router lights are blinkingWhen I googled for the error I got to know that with the above procedure I should have downloaded the file which ends with factory.bin.But now everything got screwed up. I am not able to access it. When I contacted TP-LINK customer care they are telling to buy a new one. If you change the default software then the warranty will be void.How can I solve this issue, and recover access to this device?
