When is the best time for you?

edit: I've downloaded and installed teamviewer.
edit2: I've tried re-programming the kernel two times. Still nothing.

edit3: current state of the router:
power led: rapid flashing
dmz led: steady blink every 4 seconds

This usually means the router is pingable for tftp, but I already know afterwards it will brick again so I will wait for you to take a look at it.

Going to call it a night.

Android tablet problem

Post by feedmaster » Fri Feb 03, 2012 11:51 am

I have a cheap eken m001 android tablet that you can load new firmware but it will not boot past the android screen. I have heard of people reflashing the main chip or something because it gets corrupted? It just loads and loads and loads.

Linksys WRT400N

Post by mesa412 » Sun Mar 04, 2012 12:42 am

I have a dead (power light flashing) Linksys WRT400N for which I can find ZERO support.

I can't seem to figure out how to write a script in USBJTAG_NT:confused: to detect the flash (Winbond 25X64VFIG).

Cpu: Atheros 7161 rev2

If someone could help, I follow directions VERY well.

Thanks for the tools and the knowledge. :)

Thats an SPI Flash. You should be able to Detect if. A sript Has Nothing to do with Detect. What may be Needed is an XML, However you should still be able to detect the flash. You will need to provide power to Pin 2 Of flash if you Don't Know ( And I know you Don't ) Where the SPI Point Is...

I am adding more and more SPI flash through JTAG. AR430W is an example.
I am not 100% sure if the algorithm of 7161 is already built in. 0.57 software will provide different mechanism of adding new SPI flash support by through external loadable module. But I also need more device to test on.
Your best bet is that NT already has the support and setup teamviewer and let me make the xml for you. If not you might consider donate this device for me to add support on it.

If you think it is similar to WRT350N then select WRT350N.
You did not specify which target you are playing with.

Oh, sorry, I should have been more specific.

I'm using this target

--WRT54G8M--

I get this:

USB JTAG NT 0.60

-detect

Unknown flash type!
Report these values http://www.usbjtag.com/vbforum 0000,0000


I'm doing exactly as the debrick video for WRT350N. Any suggestions?

Also I'm trying to detect the flash, using this commands:

tap c
tap a ffffffff

without success :confused:

This are the specs

Serial Num. = CNP11
FCC ID = Q87-WRT300NV11
CPU Type = Broadcom BCM4705LKFBG (BCM4785 chip rev 2)
MIPS Rev = ?
CPU Speed = 300MHz
Bus = ?
Flash Type = Parallel
Flash Chip = Samsung K8D6316UBM
Flash Size = 8MB
Max Firmware Size = 7995392 bytes
RAM Size = 32MB

IMP code is not right.
Possible reason is that IRlength is not right. Try to fix this in XML and see if it works for you.
For router, the IRlength should either be 5 or 8.

I edited the XML file, but it doesn't work. :(

You get stuck when detecting the flash.

No Light = You erased flash but did not program it right after erase.

It is Fixable. Good Luck ;)
