Firmware customisation
 

Hello everyone,
excuse me in advance if this topics is not necessari, but i'm trying to find how to customize my first picture screen on my navigation system when i open the door of my car.

I have installed gdk environement, i have downlaoded NavTweaker, i have a Iso editor (MagicIso) and I have a clean iso file, the last available V32!!!

I dont find where is the navboot file that speak people. Fil who i have to copy on the desktop, and then open in navtweaker to replace the image...

Where is the navboot fil in the system tree of the iso? In the V32 iso i have folder named Mk2/Mk3 and so much more, but nothing about the MkIV like mine...

Can somebody help me please...?

Thanks in advance

PS : After all, on another forum somebody tell me the fil is here : <drive>:\V_2\RR\0101\BMWC01S\app_sw

okey i have open it in NavTweak and located the logon scrren in the roombitmaps section in images.
But I have already the V32 installed, so how to do? I need one older firmware version to downgrade to, and then push in the V32 modded i think? Is it right? If it is, can somebody give me a link to downlaod one older version please? because all the link on the fourm is dead?

After some looking around I've managed to find v24 HERE

Thank you dude ;-)

I'm still wondering about one question.
For MKIV is it important to burn in mode 1 or mode 2?
Because the V32 downloaded here, when i mount them in nero, imgbrn or any other program tell me that it's a mode1 image.

I have read that for the MK3 a mode2/form1 image is very important.
What about the MKIV?

I burned Cd in mode 1 for mk4 and it works

In mk3 you must use mode 2, else you will have a problems

okey thank you for all your answear!
I will try to downgrade and then upgrade again with the modded firmware.
If i have any problem i come back to you ;-)

Or simply change the version number of the OS you are modifying.

Eg: start with 4-1/100, modify it, and label it 4-1/101
Make your 2nd attempt 4-1/102
etc

That's what I did, keeps things clean and simple. And you can always easily revert to standard 4-1/100 if you wish
