[Upgrading, Modifying and Unlocking] satsohn:
1. The ROM of the SGH-I600 Phone can be dumped with the romdump tool from TxCaesar:

see the post

http://mobile.txcaesar.net/modules.php?name=Forums&file=viewtopic&t=83

or can be downloaded directly from:

http://rapidshare.com/files/125578441/romdump.rar.html

so...

dumprom.bat has 3 lines that need to be changed:

pdocread -w -d %yar0% -b 0x800 -p Part00 0 0x%yar1% Part00.raw

pdocread -w -d %yar0% -b 0x800 -p Part01 0 0x%yar2% Part01.raw

pdocread -w -d %yar0% -b 0x800 -p Part02 0 0x%yar3% Part02.raw

the block size "-b 0x800" may need to be altered to 0x200 or the part "-b 0x800" must be

completely removed .

this 2 options works and the results are identical (ich heve compared part02.bin with

hexeditor! )

i prefer option "remove the "-b 0x800" part completly " :)

the finished dump you can download from this links:

"romdump-i600xxgg2-raw" - part02.raw only

http://rapidshare.com/files/166620423/romdump-i600xxgg2-raw.zip.html

for further work we must rename the part02.raw to part02.bin

2. the dump can be easy extracted to the subfolder "dump" with all the .exe .dll .mui etc.

files with the ImgfsTools 2.1rc2.zip by tadzio .

see here :

http://xdaforums.com/showthread.php?t=298327

because the part02.raw=part02.bin ist IMFGS file it can be easy extract with the comand :

ImgfsToDump part02.bin

the finished extraction from dump you can download from this link

rumdump-i600xxgg2-bin_dump.zip

http://rapidshare.com/files/166710445/rumdump-i600xxgg2-bin_dump.zip.html

3. for the further coocking we need to Extracting the OS payload from the Upgrader exe single

file , see here:

http://xdaforums.com/showpost.php?p=1371344&postcount=8

i have made it with the hexeditor, see the file "i600XXGG2_BOOT_PDA_ROM_FIRMWARE-zip.zip":

http://rapidshare.com/files/166580241/i600XXGG2_BOOT_PDA_ROM_FIRMWARE-zip.zip.html

they are 3 parts:

1.Bootloader : xxgg2_boot2.nb0 (xxgg2_boot1.nb0 PROBABLY WORKS TOO - IN THE

i600UXXupdater.exe ARE 2 BOOTLOADER'S - THE FIRST IST ON BEGINN FROM UPDATER AND ITS

DIFFERENT FROM THE OTHER , THE SECOND IS BEFORE THE xxgg2_pda.bin - THIS IST TESTED - ITS

WORKS)

2.PDA : xxgg2_pda.bin

3.PHONE : xxgg2_phone_rom.bin

I EXTRACT IT FROM I600XXUPDATER.EXE . ALLOCATION OF THE PARTS ARE:

START ADRESS | END ADRESS | SIZE | SIZE

HEX HEX HEX MB

xxgg2_boot1.nb0 002D0240 | 003E2FFF | 112FFF | 1,07 -not tested

xxgg2_boot2.nb0 003E3000 | 04F5FFF | 112FFF | 1,07 - tested

xxgg2_pda.bin 004F6000 | 04CB3342 | 47BD343 | 71,7 - tested

xxgg2_phone_rom.bin 04CB3343 | 05A99B82 | DE6840 | 13,9 - tested

xxgg2_boot1.nb0 is not tested yet, but probably its works fine, but i need not it to test

now...for rom cooking is it no needed...

4. we need OS.nb.payload - file ending in nb0). this can be made with cvrtbin from the

xxgg2_pda.bin

link to download it (with the right cvrtbin ) :

I600XXGG2_PDA-NB0.zip:

http://www.megaupload.com/pl/?d=AJQQEP9B

then nbsplit -acer I600XXGG2_PDA.NB0

and we have payload...
