Microsoft MN700 hack project

[bradmyers]

I've read thru all of the posts on here regarding the MN-700, but it's kinda kludgy. Can somone post a decent step by step guide to flashing the firmware with either the wrt54g or wl500g stuff. Perhaps some specifics on the JTAG cable and what needs to be modified in the software.

Thanks!

Well, I found this page through google, which I've read through several times. It seems that I will have a little project on my hands playing with an old MN-700 my roomates and I replaced with a WRT54G.

As I hate to see hardware not be utilized, I figured perhaps we could do some sort of wireless bridge to the xbox across the house, only to find the MN-700 firmware doesn't support it. Hopefully I can figure this out, as this will be my first time working with jtag, but I have worked with soldering and reflashing small chips in some of my classes.

After I build my cable and start playing I am sure I will have some questions, but right now I'd just like to thank you guys for the work you've put into this!

First, thank you all for this great work.

After having build a jtag cable I tried to backup the whole flash. It seems that this worked, so I thought my cable should be ok. But when trying to flash the new cfe, I get a few (10-15) "ERROR ON READ". And when I backup the newly flashed cfe it differs from the file on disk and after powering on the device I can't tftp the new firmware. So I think something (flashing) isn't working yet. Is this a cable problem? My cable is around 8 cm and I used the v2.2 of the debrick util.
Anybody an idea?

Thanks!

flash the new cfe, I get a few (10-15) "ERROR ON READ". And when I backup the newly flashed cfe it differs from the file on disk and

that sometimes happened to me too, especially when i loaded the system (watching a movie etc) whilst flashing, and everytime i got that i had to restart (restart flashing). you might try using linux (you'll need to a) edit the source, remove the chiptype check and b) "insmod lp" before flashing)

Hi
I was wondering, would the pin trick (http://openwrt.org/OpenWrtDocs/Troubleshooting) work on the mn-700 with stock firmware/bootloader? If npt, guess I'll have to build a jtag cable soon ;-)

Hi All
Just wanted to say that now (thanks to Oleg!) my MN-700 rouns the 1.9.2.7-5 firmware. Did the flashing from my Novell Linux Desktop installation on my old laptop. Had to make an alias for parport0 in modprobe.conf before it worked. Also, doing a telinit 1 made a lot of difference, as all flash attempts from runlevel 3/5 failed...

About the cable... THE PICTURES IN THE DEBRICK PDF ARE MIRRORED!!! Just pay attention to the pin diagrams, and youll be fine :-p

Now, how do i solder on a USB port? ;-)

cheers

Do you really need this? If so, post your system log (reboot first) and make a hi-res picture of the BCM4702 and surroundings on the top side of PCB and from the reverse side of PCB.
