In-Depth Howto on Fixing Bricked MR3040 (with Arduino Uno)
This video Shows how to use the serial UART interface on the TP 3040 to flash the firmware once you have been locked out of the web or command line interface. This video uses an arduino uno as the FTDI adapter but applies to normal adapters just as well.
Tools needed:
-Soldering Iron
-Wires
-A TTL adapter or Arduino Uno
-A Computer
Programs Needed:
-A Serial Terminal Emulator like Putty
-A tftp server like OpenTFTP
Firmware
-Either the Stock Firmware from the TP link website or another firmware like OpenWRT
-IF YOU GET THE FIRMWARE FROM THE TP LINK SITE, BE SURE TO MIND THE SECTION ON THE OPENWRT WIKI THAT MENTIONS STRIPPING THE BOOTLOADER. I forgot to cover that part in this video. :(
NOTE: I really don't make videos and I stutter quite a bit in this. ^^;; You have been warned. lol
