Since you stated you worked for qualcomm, can you shed any light on this and how we might possibly be able to write nand from download mode? Or get back to debug mode instead?

This is where mine is stuck. Thanks to these forums I can at least put it into "Download Mode." I will gladly ship you mine to screw with.

Hey Madman,

did you happen to see this thread? http://forum.xda-developers.com/showthread.php?t=372305
JockyW seems to have found a way to get past a 2a brick with a new program called Frankenkaiser.

Take a look and see it is an easier way to possibly unbrick than the jtag route. Although it may be specific to Kaiser.

Not forgotten
Greetz all,
Yes I am looking at that now. Ikon was nice enough to send me his bricked unit and I have been pokeing around and been able to write to and read from memory. I did gently take it apart and did a very good look see and find no evidence of an organized jtag interface, but that is not so bad because the unit can still be talked to and if I can adapt a bootloader to it and get it to the right place I think there will be life again. I have put it back together and the only evidence is the voided label so it will still be a good looking unit when I get it fixed for IKON ;) and I will ;)

Not giving up, just slow

Let us know if the device was unbricked ?

I´m really interested on JTAG stuff because I need some help, let me explain:

I have little JTAG experience on broadcom based routers like the famous WRT54G, but now I´m searching for information about JTAG on cell phones, by now I have to try on a lovely remembered Kyocera Slider SE47 dead some years ago (bad flashed with se47.exe util), but with the hope that someday I can have the time and knowledge for bring it back to life... I have the service manual and located the JTAG pins but I don´t have the required cable and most important the required software, can you please help me? can you share with me schematics to construct cable and software to comunicate with the phone, have a MSM5100 processor with flash chips ST M32W655D...

Have a nice day.

Thanks.
