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.

Program pass, if no further programming needed, power off/on the target

Compare data OK
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
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
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 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...mesa412 wrote:I have a dead (power light flashing) Linksys WRT400N for which I can find ZERO support.

I am adding more and more SPI flash through JTAG. AR430W is an example.mesa412 wrote:I have a dead (power light flashing) Linksys WRT400N for which I can find ZERO support.

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.
