I installed the latest version of openwrt for this CPE710, but I wanted to revert back to stock to play around with the stock firmware and I tried flashing CPE710(US)_V1_20201208 but it just seems to brick it. So I go into tftp and recover the openwrt firmware...but can't seem to get this thing back to stock for some reason. There is no option for firmware on the tp-link website for Ver 1.8 of the CPE710. This is a CPE710(US) Ver: 1.8 but the stock firmware I am trying is not working. So I was wondering if there was a copy of the stock firmware for Ver1.8 somewhere or I am doing something wrong in the flashing process...though it doesn't seem so, since I can revert back to the openwrt firmware everytime.
