So I've been doing some ASCII dumps of the "Loading.kwi" file and revealed this text -- looks like our navi system runs Windows CE:

. .T.h.i.s. .K.e.r.n.e.l. .w.a.s. .b.u.i.l.d. .f.o.r. .S.H.-.4. .C.a.r. .N.a.v.i.g.a.t.i.o.n. .S.y.s.t.e.m.........W.i.n.d.o.w.s. .C.E. .F.i.r.m.w.a.r.e. .I.n.i.t.........K.e.r.n.e.l. .V.e.r.s.i.o.n. .:. .%.s.......O.S.-.N.R.2.6.1.-.1...2.1...

Hopefully someone can find a tool to extract .kwi files -- I found one but it just crashed while parsing our loading.kwi file.

Can i ask how the hell you educated yourself about this?


klas -> RE: MMCS HDD Unlock -- Success! (10/24/2007 1:35:31 PM)

my guess it's called some kind of engineering school and passion for hacking :)

Bingo!

School and both of us work in the tech industry where we deal with this sort of stuff on a daily basis.  Your comment cracked us up, btw.  Plus, we've been fiddling around with stuff like this most of our lives.

It took us less than 48 hours to create the interposer, solder, test, capture, and analyze the data.  The two hardest parts were figuring out why the damned MMCS took so long to send the unlock password and the twos compliment of the captured data.

Interesting![sm=interesting.gif]

If MMCS is really a set of applications running on customized WinCE system, things might look even more promising. There are tons of tools in the Windows world.

The Audi tool is no good for it because it assumes the image is for unix.

Please upload the loading.kwi  to somewhere like rapidshare so that other members including me can take a look at it.

great job guys! :)

personally, I wouldn't want to temper with my navi for warranty reasons and being lazy of course. Besides, not even once I used it to save audio files. I just use free sirius radio and once "free" is over I will pay for subscription. If I want to listen to my own music I would just use external mp3.

The Hitachi Durastar J4K50 is actually 50GB. But no one is selling it yet?




Here is a seller from UK:

http://www.span.com/catalog/product_info.php?products_id=8414

But it seems that you have to order 5, that's 5 * £117.00 excluding VAT.
The deal is not as good as CDW offer.
