Rom Kitchen

Samsung i780 rom kitchen - version 0.2 BETA

Part 1: Convert Part02.raw into bin

You need:

1. an existing bin PDA rom

It's important that the rom file you use it's as largest as possible.

In fact, at step 9, you have to update a file derived from this rom

(i780.nb0.payload.body) with the content from Part02.raw: if this file is too small,

Put Part02.raw (with this name) in kitchen folder

Let's go:

1. Double click on ConvertPart02RawToNb0.bat

2. Fill input.txt with the correct parameters (look at Part 3 for instructions)

3. Double click on ConvertNb0ToBin.bat

4. At the end, you'll find i780_flashable_bin.bin in kitchen folder: that's the flashable PDA

bin.

Limitations:

Now I explain in detail all the steps in the ConvertPart02RawToNb0.bat file.

1) Put your existing rom bin in the kitchen folder and rename it as i780.bin and put Part02.raw

(with this name) in the same folder

2) Convert bin to nb0:

BinToNB0 i780.bin i780.nb0

This will generate i780.nb0 file

4) Split i780.nb0.payload.body to separate header from body:

split i780.nb0.payload

This will generate i780.nb0.payload.header and i780.nb0.payload.body

5) Now, make the imgfs file needed for step 7

prepare_imgfs i780.nb0.payload.body -nosplit

This will create a "dump" folder with all the files from Part02.raw

7) Now, you have to build a new imgfs file, using the one at step 5 as template

imgfsfromdump imgfs_raw_data.bin new_imgfs.bin

8) Delete old imgfs_raw_data.bin and rename new_imgfs.bin

del imgfs_raw_data.bin

This step won't apparently produce any output: i780.nb0.payload.body will have the same

size and last access date and time. But it will have changed.

10) Now, merge payload header with payload body

merge i780.nb0.payload.header i780.nb0.payload.body i780.nb0.payload

This will overwrite original payload file

Now run ConvertNb0ToBin.bat, after filling input.txt (look at Part 3 for instructions).

Part 2: Cooking your own rom from a previous one

You need:

1. an existing bin PDA rom

Prerequisites:

and files, modules and (possibly) change the registry.

3. Double click on RecreateBin.bat

4. Fill input.txt with the correct parameters (look at Part 3 for instructions)

5. Double click on ConvertNb0ToBin.bat

6. At the end, you'll find i780_flashable_bin.bin in kitchen folder: that's the flashable PDA

bin.

Limitations:

This kitchen needs testing.

At the moment it's not clear if you can add content to rom, exceeding its original size.

Now I explain in detail all the steps in the CreateDump.bat and RecreateBin.bat files.

1) Put your existing rom bin in the kitchen folder and rename it as i780.bin

A) CreateDump.bat

2) Convert bin to nb0:

BinToNB0 i780.bin i780.nb0

This will generate i780.nb0.payload and i780.nb0.extra

4) Split i780.nb0.payload.body to separate header from body:
