Help Changing Modem of GT-S6102B by Modem of GT-5360

[joseluisbz]

Cordial Greetings

I'm interested to change modem of my Samsung Galaxy Y Duos (GT-S6102B).

I'm from Colombia...
I bought a Samsung Galaxy Y Duos (S6102B), It Came with Gingerbread 2.3.6.

Version Kernel: 2.6.35.7 se.infra_AT_Sign_SEI-44 # 1.
Number of Compilation: GINGERBREAD.VJLC3.

*#1234#

PDA: S6102BVJLC3
PHONE: S6102BVJLC3
CSC: S6102BUUBLC2

In Colombia the frequencies for WCDMA are 850MHz/1900MHz.

My GT-S6102B has preselected 900MHz/2100MHz Brazil and Asian frequencies, and I need to enable 850MHz/1900MHz for gain advantage of HSDPA (3.5G) data connections.

According to List of UMTS networks - Wikipedia, the free encyclopedia

• Mexico has 850MHz/1900MHz
• Uruguay has 850MHz/1900MHz/2100MHz
• Venezuela has 850MHz/900MHz/1800MHz/1900MHz

As I have understood, is possible to change (Modem/phone) of S6102B taking (Modem/phone) of S5360.
Reviewing firmwares that can be candidates to unpack I have:
Mexico: http://www.hotfile.com/dl/164153315/...1_UNE.zip.html
Uruguay: http://www.hotfile.com/dl/157180385/...1_UFU.zip.html
Venezuela: http://www.hotfile.com/dl/150336037/...1_VNO.zip.html

I think that S5360 Firmware of Uruguay is better because is more recent and more complete.

For other changes, I will take as a base the S6102 Firmware of India.
India: http://www.hotfile.com/dl/165818294/...1_INU.zip.html

My intention is to mix the S6102 firmware of India with the S5360 firmware (modem part) of Uruguay.

I want to know if is possible to make changes according to compatibilities of Modem/phone for these models.
I want to know how I can do successful this process. If you have a guide/advise for me, I will be grateful.

Thank you,

Best Regards,

Jose Luis
