Dumping and Building a ROM

If you want to build your own ROM, you first need to build one. I will guide you on this.

1. Setting up the kitchen

First, you need a kitchen to work with. A kitchen is just a set of tools combined which work together.

You can find the kitchen over here

Once downloaded, unrar the file to a location you'd like. (I'm using D:\B7610kitchen for easy access).

Please note that using empty spaces inside the full path (like D:\B7610 kitchen) is not recommended!

Finally, get a ROM_DUMP.bin from a official ROM. Already cooked ROM's will not work!

Copy the ROM_DUMP.bin to the 'template folder'.

This will result in something like this:

2. Dumping your ROM

The kitchen is now ready for use! Fire up 'RomTool'.

Set the 'work folder' (top-left) to the template folder I included (or if you renamed it, choose that one).

Once done, click 'Select File'. If you followed the previous part correctly, you won't have to switch folders to see rom_dump.bin. Select it.

If checked, click the 'Run' button. RomTool will execute and start the dump-process.

If RomTool finishes, you will see this: (watch the log-area)

Next, go to the 'settings' tab, and click 'Start ExtReloc'. A new window will open, click the 'Options' tab.

Set the settings like I did below.

Once done, click 'Save Options'. Nothing happens, don't worry. Close ExtReloc but keep RomTool open!

You have now succesfully dumped a ROM into OEM/SYS folders. From here, you can do with your ROM whatever you want!

3. Building your ROM

NOTE: FOLLOW THESE STEPS AFTER YOU MADE CHANGES TO YOUR ROM!

Go back into RomTool. Select the 'Build PDA file' tab.

Set the options like I did below.

Done? Click 'Run'. Xipport will open and work on the XIP. More on this is in another post.

Next, BuildOs will open. If you added OEM's (again, switch to another post in this thread for info on OEM packages!) they will show up here.

Click the 'Play' button. Once finished, close BuildOs. RomTool will finish it's work.

Note that building a ROM takes a lot of processor power and time. If I cook a full ROM, it takes about 10 minutes on my high-end notebook.

If everything was OK, your new ROM should be in the 'Finished ROM' folder.

Is it possible to dump a nonofficial rom? I maybe want to do some tweaking on the Daskalos Sense ROM.

I did, but that was by selecting a .bin file. Maybe it is possible to get a .bin file instead of an .NB0, for cooked roms. It MUST somehow be possible to load custom roms into it. I bet Daskalos didn't make all of his roms in one run, by only opening the program once.

No, it isn't.

Once a ROM is built, the RGU files are removed. There is no way to get those back.

Edit: You cán however use the dumped files again. So if any bugs exist you can easily modify the ROM again and re-build it.

So the only way to modify custom roms is by asking the cooks for all the files?

You could try, but I think they won't share as it's their own work.

imgfsfromdump.exe crashes while building my os. any idea what could be causing this? i tried running it separately from command prompt over the dump folder - it runs fine and builds a new imgfs file.

however, when i try and use osnb it says part2 size is wrong...looks like the imgfs size is incorrect :(

any pointers?

EDIT: and yes, i have dumped from an official rom - jc2 rom.

You should set the 'work folder' again when building a ROM.

Try it again after a minute or 2, you should be able to download it.

Our devices use different files, so imgfsfromdump won't recognize it.
