Ok first of all, I typed these instruction in about 10 minutes to HELP a FRIEND from the original thread on xda-developers, Which i will save you the trouble of linking yourself http://forum.xda-developers.com/showthread.php?t=414778 Here. It was 1 am in the morning and i didnt think to add in people who helped me as I have linked from these forums to my thread on xda SEVERAL times. I guess I was wrong in the since for not doing that and im sorry if someone was offended by this. I NEVER claimed this information to be my own, nor did I say i knew this all from the start. The name calling and trying to bring me down is plain ****ing childish if you ask me. I wasnt even going to publish this to begin with but i decided I would post this to help some of the other novices out there like myself who had a hard time with this. ok Here we go: I got the info from http://forum.xda-developers.com/showthread.php?t=414778, and http://forum.xda-developers.com/show...ht=XIP+porting . These are my 2 any only sources. SORRY for not linking these before. I simply wanted all of this information to be in one spot to help others. Now if you want to continue to call names and try to make yourself superior or seem better go ahead i could care LESS. BTW this is not pointed at one particular person but the group that decided it was kool to call names and critisize me.
Have a nice day,
Chris

So NOBODY helped you with anything? Those are your ONLY two sources? Seems like you learned a lot then... =D> Good job! ](*,)

No. That doesn't signify the beginning of a xip. That's why no one says to do it that way.

The source is not available and that was designed for WM5.

wait... what wm6+ doesnt use that method anymore... so how do we detect the beginning of the XIP, by the looks of the file in a hex editor, there are still 2 xip sections right? oh and there was a password protected rar in my titan folder on the ftp before whoever erased half the ftp :( but is/was my tool

Re: XIP Porting GUIDE!!!!

wow im amazed at what this turned in to. he posted because i was having issues and he had ported so i was wanting to learn. this is why the developers leave. just because he didnt give people credit immediatly doesnt mean he wasnt gonna. we all have personel lives and he posted some information that helped me out he may not have gotten to alll the credits at the moment but damn it was one in the morning i remember the second he posted. its really pretty childish that all yall care about is the credit thing. someone did actually care about the devices but he started off with calling him a tool. really thats what the senior members of this site have resorted to name calling and bashing im very disappointed at what yall have become. this site is one of the best places on earth to get info that is apparently till you get to a certain point. this was really posted so that people wouldnt have to put up with more people like us. so that the info could be spread this place is full of knowledge but its also full of people who survive solely on there ego. somem mod needs to close this thread down let people cool because i see this getting even further out of hand than it already is.

Re: XIP Porting GUIDE!!!!

the whole start location thing.... well here's a quote...

don't dump with rommaster (manually extract the rom)
to do this, first nbsplit, then on payload...
run imgfsfromnb. write down the imgfs start location.
open os.nb.payload with hex editor. go to the imgfs start location, and delete to end. go to the beginning of the file, and search for FE 03 00 EA (unconditional branch to 00 03 FE), and find the second / last occurance. (this is the second xip).
delete everything from the beginning to just before the second branch.
save this as your xip.bin

open xipport. press dump xip.bin. move stuff around, checking the maps between the donor xip and your xip. when you're done, press realloc p, and write maps. if any area shows !!!, fix it. (usually, modify realaddress[r] in imageinfo.txt, where r is the xipregion).

technically, you might need to check the nk.exe pointer in S000 of nk.exe, but i think realloc p fixes that (maybe). if you're worried, from the old map of the xip (not from the donor, but your device), search for the rom_00 header, look at where it starts, check if it matches with the new map If it doesn't you'll have to do this: if the old start address is 8ABCDEF9, search S000 of nk.exe for F9 DE BC 8A (just an example), because of the endianess of arm. replace with new start address, be sure to reverse it as well.

once you're done, write xipout.bin, and write it to os.nb.payload at the right xip2 address (for the titan, its 3200000) (sleepy and not sure if i put the right amount of zeros, but the default is 3100000, so change the 1 to a 2.)

hopefully everything boots up after this. I've used this technique to change everything except nk.exe... which is device dependent, so you'll have to do other stuff...

Re: XIP Porting GUIDE!!!!

:) This is why I stick to the easy stuff like tutorials on "porting" a .tsk file to an OEM... :) Hehe...

Your method may work, but there's no guarantee it will work. Hence, it isn't the advised way of finding it.

You're not referring to fayfay aka dainja as a developer are you? I'd honestly be surprised if he could develop a rash.

Erm, even after being called out he said his only sources were two threads on xda.

this was really posted so that people wouldnt have to put up with more people like us.

Dear Lord! There are more of you?
