DMA not supoorted

If still not work, send me the datasheet of pdf and I can add it to the flash.def.

Thanks for the help!! I tried to follow that post but I am lost lol :P

I attached the files that need to be edited, if you could do it and re post them for me, or write the code and tell me where to paste it. That would be awesome!!

Thanks again man, for the quick reliable help. You rule!

[usbbdm]

If I were you
I will first read the label of the flash chip. Go online and find the datasheet. If you still cannot do it send me the pdf, I will make a post on how to add one line with that pdf.

BTW, the new USB JTAG NT will use xml definition for flash.

Ok awesome, where is the flash chip label? I see a cpl little chips, the one that looks like the ones on sb modems says;

M28W160CT
90N1
5EQRV
0326
ITALY

And the BIG one says this;

TNETC4401PYR

Thanks! Worked like a charm. For anybody using this, make sure you have the software configured for a 5120 :P Then it works fine. Thanks again!

OoopsiEZ!!

I bricked the modem I think lol, don't be a noob (like me) and try to write hax0ware to it..

[usbbdm]

This modem should be able to restore to its original state. It is not bricked.
Programming the unknown firmware is not recommended as you will spend more time to fix the modem.

Yea, i was able to grab a sh!tload of firmwares from rogers tftp servers a month or so back. I have a bunch of toshiba firmwares from pcx 2600 and 2500. I am going ot mess around and see what the modem take maybe (which i doubt because of part differences) I can get a hacked firm onto it?

PS:

If any of you should want any of the firms, i can make you a list and post them. They are ALL rogers signed as well. There is almost every cable modem firmware in the list. (not every one for every model, but 1 for alsmot every type, like webstar, smc, motorola etc.) Just pm me and I will make a thread or send htem via pms! )


Thanks usbbdm for all your help in getting this to work! I appreciate it a lot!
