Many of my friends were asking for tutorial to get back to stock Rom ,so Here’s the procedure on how to manually install the stock ROM (firmware) on Samsung Galaxy Y Duos GT-S6102 for all of them.
Flashing stock ROMs is useful in downgrading or upgrading to any available firmware versions you desired. This has been also useful for unbricking purposes for a bricked, reverting back to original stock or if you needed your device warranty back.
This guide is a bit risky for beginners and can only be used by advance users who already had an experience on how to tweak android devices firmware.
Now, this procedure is no joke and should be taken seriously for it might results to damage your phone if some mistakes might happen. i’m talking about firmware flashing here, one false move or any interruption will take your device into serious situation that is not too easy to recover.Your phone is not a toy for us, but it is your personal property, you are the only one who can decide on what to do about it.
i’m not be held responsible if anything happens to your device by following this guide. Proceed at your own risk!

Back-up all of your important data stored in the phone like contacts, messages and etc. Flashing will wipe and delete all of it.
Ensure that your phone is fully charge or above 80% charge. (If your phone had an auto-shutdown history, and its too old, use a newer or good working battery.
Remove the SIM card and the external memory card. (not necessarily but recommended to avoid any certain issues)
Hard Reset – We often do hard reset before flashing to clean the memory cache of the phone. Master reset code *2767*3855# .
How to Flash with Multiples files with Pit, Bootloader, PDA, PHONE/MODEM and CSC file
This is full flashing and useful for unbricking for it has a full packaged with individual file allocations, this type of files we often used to fix a bricked Samsung Android devices. Some firmware updates have like this one and some are came into just a single file packaged.
Click on each button and load the appropiate file unto it.
Pit Button – select and load the torino_1205.pit
u need only 3 file
PDA button – look for the file with the letters PDA or CODE on it,
like PDA_S6102XXXXX.tar.md5 (also .tar support)
PHONE button- look with the word MODEM file,
like MODEM_S6102XXXXX.tar.md5 (also .tar support)
CSC button – associated also with letters CSC or Multi_CSC,
like GT-S6102OXXXXX.tar.md5 (also .tar support)
There are three checkboxes on the left side of ODIN, the Re-Partition, Auto Reboot and F.Reset Time.
The Auto Reboot and F.Reset Time are often always checked in flashing while the Re-Partition will only be checked if you want to fix the memory partition of the phone, now if you’ll only want to upgrade or downgrade DO NOT CHECK THE REPARTITION.
DO NOT CHECK RE-PARTITION – Safety for Upgrade and Downgrade
Full Flashing with RE-PARTITION enabled – Advisable only for fixing Soft bricked devices
