I've just try to revert from gargoyle to original firmware (TL-MR3420 v1), but after that, the web interface keep displaying this:
Username or Password is incorrect.
Please refer to the troubleshooting below:
Is the "Caps Lock" enabled on your keyboard?
The username and password must be lowercase, please ensure that the "Caps Lock" LED is disabled on your keyboard and try again.
Forgot your username or password?
Please reset the device to the factory default settings if you have forgotten your username or password. The default username and password are both set as "admin".
Note: The settings will be restored to factory default after the resetting.
How to restore the device to the factory default settings?
Firstly locate the reset button on the rear panel of the unit, whilst the device is powered on press and hold the reset button for more than 5 seconds, the device will then reboot and restore itself to the factory default settings.

Wifi is working and has original SSID ie TP_LINKxxxxx and original IP address too (192.168.1.1). But, the weird thing is that it is always redirected to http://192.168.1.1/cgi-bin/luci
I've tried telnet or ssh, but both didn't work
Please help
