Hi all, this is the time for knowledge sharing again~

This is a tutorial about how to extract baseband ONLY from a .tar.md5 ROM zip.

U can download the latest firmware from
http://samsung-updates.com/gt-i8150-galaxy-w/

What u need?
  1. Firmware with desired baseband
  2. Cygwin (get it from http://www.cygwin.com/)

Steps
  1. Install Cygwin and start the Cygwin terminal
  2. Put the .tar.md5 firmware into c:\baseband
  3. In cygwin, type the following command
    Code:
    cd /cygdrive/c/baseband
    tar -xvf firmware_name.tar.md5 amss.mbn
    tar -H ustar -c amss.mbn > baseband.tar

    P/s: If the firmware_name.tar.md5 is I8150DXLM3_I8150OLBLD1_I8150DXLM2_HOME.tar.md5

    Then the code will be:

    Code:
    cd /cygdrive/c/baseband
    tar -xvf I8150DXLM3_I8150OLBLD1_I8150DXLM2_HOME.tar.md5 amss.mbn
    tar -H ustar -c amss.mbn > baseband.tar
    The results u will see should be like this pic

After all the code typing, u will get the desired baseband.tar which can be flashed as one package by using Odin. U can flash the baseband no matter u are using custom ROM or Stock ROM.

Just a advise, baseband is region-dependent. Although it is still working worldwide, u might have the problem of not receiving sms/call if u are using a baseband from another region.

Sorry, but i think to get the same result in the following way and more simply.

- get the complete firmware file
- make a copy and open it with 7zip or winrar
- delete files you dont need. Keep only amss.mbn

it's correct?

One question guy, what is the file 'adsp.mbn' that is in rom?

thanks and bye!

Yes u can do that. BUT u will get md5 checksum mismatch problem because the md5 is generated for the whole firmware file not the amss.mbn alone.

It is the baseband.

What do u mean extracting the whole .tar.md5? u can simply open it via winRAR/7zip. Then extract out the img.ext4 and open it via ext2explore. those .img files can be opened via DiskInternals Linux Reader.

Please use odin to do that. I am not sure whether CWM can do it as it involves installation, not replacing files.
