Re: WRTP54G-ER JTAG Unlock using windows

reply to voiplover
Seems the software link no longer works, is there a working link to the JTAG software?

Also are the PCB layouts for the header the standard 0.100" center to center for the header or something else?

OOPs! It said I violated their TOS???

Well, when they let me out of the slammer (due to the TOS) we'll have to do something about it.
It's probably on the other thread, if you can't wait. Or maybe some one else can post it!!!

Thats where I lokoed first, and it too was a BigUpload link.

Sorry people, the harddive that had that info on it was one that cooked a long time ago. There are several members here that should still have it so Hang in there.

It is possible that I burned it to a CD or copied it to another drive, but it'll be a while before I can begin to look.

I finally have it works.
In general I followed voiplover
»WRTP54G-ER JTAG Unlock using windows

and lambition the steps as below,

»[WRTP54G-ER] How to unlock and re-use this earthlink device.

I'm just add more detailing the steps that worked for me. All credits to those that did the real work.

Soldering is simple, BUT you MUST be VERY careful. If your soldering iron is the old one, clean the iron head with sand paper before do the job. Too much solder will create short circuit.

After soldered the 100 Ohm resistor and the ground line on the circuit board, you should use a magnifying glass to check the up and under side the possible short circuit because the circuit board lines are very tinny, the visual check is necessary.

The step #4, my XP windows directory is c:\WINNT, therefore if your XP windows directory is different from C:\Windows, make your name change in step #4 and #8. e.g. C:/???????/system32/drivers.

The step #8, the path should be "c:/windows/system32/drivers". You do not have to repeat this step again if you completed the step#14. But if have problem in step #10 to #14 and RESTARTED your PC, then you need to do the step #7 and #8 again.

After the step #14, your screen should be shown some block of flash address was erased as following screen shot.

Then reboot the WRTP54G-ER, go into the Administration/Firmware Update/ to update the new firmware. The firmware should already download before you start this unlock process.

Good luck everyone! My WRTP54G-ER working Super!!

Have done about 8 of these so far over the past 3 months, and all are working flawlessly.

I soldered a pinheader onto the motherboard, and put all the resistors inside the cable connector casing, with a female pinheader in the other end.

Hey ahchu.

Can you post link for your wrt54g.exe
Looks like you have the same Flash S29GL064M-... as I am.
And I couldn't find wrt54g that support it.
Or maybe you can upload it somewhere.

Thanks.

It's easy to check what flash IC wrt54g support by run it in
"Command Prompt" window without any keys.
It'll give you a list of supported Flash chips.
The one You post here - is generic one because it doesn't have S29GL064M-.. listed.

And from ahchu screenshot looks like he has one we need (with Spansion support).

reply to voiplover
Ok, I'm finally did unlock mine WRTP54G-ER.

But I was correct about wrt54g.exe - has to have a support for Spansion Flash IC. And I have to compile new wrt54g.
After that everything went flawless.

Thanks to this forum.
