[HOW TO] Extracting baseband from .tar.md5 ROM

---

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
   

   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:
   
   

   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.

Great, Thanks

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.

how about extracting the whole .tar.md5? what's the code for that?

thanks for the tutorial

EDIT: I just get the code for the whole rom. thank you

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.

And how we do for flash the baseband via CWM?

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

hi I'm a noob
