Overview
The TIAO USB Multi Protocol Adapter (TUMPA) is a multi-functional USB communication adapter for hobbyists or engineers. The adapter is based on FDTI's flagship communication chip FT2232H, a USB 2.0 Hi-Speed (480Mb/s) to UART/FIFO IC. It has two multi-protocol synchronous serial engines (MPSSEs) which allow for communication using JTAG, I2C and SPI on two channels simultaneously.
In this tutorial, we are going to show you how to debrick a wireless router. We use WRT54GS as an example, however, it doesn't mean than you can only debrick WRT54GS with TUMPA. You can follow the same instruction to debrick other wireless routers.
Required Hardware and Software
- Obviously, a bricked wireless router (in this example, I am using a bricked Linksys WRT54GS)
- TIAO USB Multi Protocol Adapter (TUMPA)
- Wireless router debrick software XJTAG
Disassemble your router
The first step is to disassemble your router. In this example, the WRT54GS is very easy to disassemble. See reference here: Debrick Routers Using JTAG Cable. If you don't know how to disassemble your router, just search it on google :-)
Locate the JTAG Header/Pin on the router's PCB board
The JTAG pin on the WRT54GS is the JP2. See reference here: Debrick Routers Using JTAG Cable
Install TUMPA Drivers
Depending on your system, you can follow the following tutorials to install the drivers on your Windows machine:
How to install TIAO USB Multi Protocol Adapter Driver on Windows XP How to install TIAO USB Multi Protocol Adapter Driver on Windows Vista or Windows 7
Once the driver is installed, unplug TUMPA from your USB port.
