Re: WRTP54G-ER JTAG Unlock using windows I ordered one of the Fry's 29.95 specials last week. Screwed around with the HTTP server stuff and never could get things working. I finally did the JTAG (homebrew from parts) and it was easier than I thought it would be. Thanks to all that have helped with this device and especially the JTAG method. I now have a WRTP54G-NA (Was an ER) |

| I just got a WRTP54G-ER from Fry's. I wanted to check if this one is good or not, so I just hooked it up with my Comcast cable modem and computer, just using it as a normal router. It only worked for a few minutes, and then did not show any internet connection. I noticed that the firmware has been upgraded from 1.0.48 to 3.1.14 without any notification by itself.
Can I still use JTAG cable to unlock this router now with Firmware 3.1.14 from earthlink? Or, should I just return it to Fry's? Thanks a lot for any suggestion! |

| Yes, you can still use JTAG to unlock it. In fact the last one I bought came with 3.1.14 and I could unlock it using JTAG. |

I ordered one of the Fry's 29.95 specials last week.It turns out that my wrtp54g does not come with header-pins.
I read the thread all the way down but confused.
Do I need open the router and the pins are inside? if so, is the JTAG cable small enough to fit inside the router?
Thank you guys in advance. |

kudos:1 | said by pengdaya:It turns out that my wrtp54g does not come with header-pins. How can you make such a statement unless you had not opened up the device to inspect?

Thanks a lot. But I kept getting a message like this and I cannot have access to 192.168.15.1. Anyone can offer a clue? Many thanks!

As mazilo said, you will have the answer. Send me an email, and perhaps I can show you something though I am still having a problem. |

Got my problem solved. It was caused by long wires without shielding. Short wires worked immediately.
I used a scheme which combines MAPS, Fixup, Voiceipuse and VOiplover's:
(1) Parallel cable's 18~25 are connected together at port side (it was like that), the other side is connected with JTAG pin#12, Serial pin GND (Most Right Side)
(2) JAG pin#1 + 100Ohm + JTAG pin#14
The others are the same.
Thanks a lot for all the information providers! You guys have done a great thing! |
