Linksys Router Help!
Hi, I would like to start by saying that, I have this old Linksys router, I don't use it anymore, but I wanted to put custom firmware on it. Something went wrong, while upgrading the firmware, therefore, bricking my router....
Here is a list of relevant details that might be useful to solving the problem.
-Router Model Number "WRT54G" (Version 6)
-I tried a ping test (VIA Command Prompt, a tool included in most Windows packages) and got a live response, so the router is still functioning...
-I cannot use JTAG, as my laptop doesn't have a parallel port on it..
-A website that lists information on this router, listed a brick code, that can be seen on the Power LED and DMZ LED flicker patterns. This code tells you why it cannot boot. (list at the bottom, taken from DD-WRT)
My router indicates a defective bootloader.
Another thing is, the router has a "management mode" on it, which is supposed to allow you to upload a (.bin) file for the firmware. I was able to access it, but had no luck restoring the firmware...
For those who don't know, JTAG is a connection on the router, ONLY accessible by accessing the motherboard. that connects to a parallel cable to a PC, the manufacturers used this to load the first firmware to the flash memory chip, my PC doesn't have this port, so I would hope that JTAG is not the only option for fixing this...
I do not know much about JTAG, feel free to search it...
How could I be able to debrick my router? Any ideas?
See ya! -Zeke
Here is the list :
"1 . The power LED flashes very fast. If it keeps on flashing longer than 2 minutes, without having lit up the other LED's, then a defective bootloader is present. However, if you can ping 192.168.1.1 (your router IP) you can try the TFTP recovery, otherwise you may need to open the router and use the JTAG recovery method below.
2. The power LED flashes very fast and after some seconds the DMZ LED lights up for approximately 5 seconds. In this case the Bootloader is intact and only the kernel (firmware) is defective. In this case you could possibly still recover with an ethernet cable if you reflash the firmware via TFTP (see TFTP below).
. The power LED flashes very fast and after about 20 seconds it lights permanently, but the DMZ LED did not light up. In this case Bootloader and Kernel (firmware) are intact, only a wrong configuration from locked up the router. This can happen if a wrong or corrupt value exists in the NVRAM. Here simply clearing the NVRAM should solve the problem." - DD-WRT
