Hello
After i tried OpenWRT in my C7 V4 I decided to go back to stock. After the sucessfull TFTP flash back method, my device rebbot and the default TP-Link new password page shows but after i gave a new password, the OpenWRT LUCI page displays but fails, complaining about LUCI package is not correctly installed. I tried reset my factory settings, via the hard reset method, the OpenWRT safe mode reset method but nothing helps. I uploaded via TFTP different versions of stock firmware but the results always the same. Where this LUCI thing are came from? How can i delete it? After a few hours of tries, I TFTP again the tried (latest avail) OpenWRT firmware and my router is working with OpenWRT but how can i go back to the stock? (The reason is switching back to stock is the very big difference of WAN speed, stock can achieve 450mbit-650mbit/sec and OpenWRT only achieve 80mbit-150mbit with my internet provider pppoe connection)
