Important Reminders before Flashing Galaxy Ace 2 GT-I8160 Stock ROM

- Make sure that your Galaxy Ace 2′s battery is fully charge.
- Stock ROM packages comes in two formats the ‘Full-Wipe’ (delete your stored data after flashing) and the ‘Non-Wipe’ (it doesn’t delete your phone’s stored data) but it is highly recommended to make a back up all important files stored from your phone’s internal memory – contacts, messages, etc.  before flashing no-matter if it is Full-WIpe or Non-Wipe,  just to be safe and ensure that your stored data are in  safe  if something went wrong during the flashing process.
- Remember or back up the APN settings of your device. ( This only done if you try to install other regions stock ROM.
- Use a PC or laptop that runs in Windows OS, with a good and perfectly working USBserial port.  Odin will not work on MAC OS.
- Use the supplied USB cable for your Galaxy S3.
- Enable USB debugging from your phone’s settings. Go to Settings > Applications > Development, and tick the box that says ‘Enable USB Debugging’.
- Do a “Hard Reset” if you have a lot of 3rd party applications installed from your phone, this is useful to gain a smooth flashing. (Just make sure that you already back up all your important files before resetting your device.
- Ensure that KIES is closed and not running in the system tray! Kies will interrupt and doesn’t like Odin, it will block you from flashing.

Step 1: Download the needed tools for flashing
Odin Flasher Odin3_v3.07 link Tool and USB Driver Ace 2 USB Driver

Stock ROM: Portugal (TMN) - TMN_I8160XXDMC8
UK - BTU_ I8160XXDMC8 download

Step 2: Extract the downloaded stock ROM
You need to extract the downloaded file which is packed in zip files, so that you’ll get the tar.md5 file. If you miss this step you’ll only get error.

Step 3: Run and Configure Odin
Run Odin downloader Odin3_v3.07 on your PC desktop. Watch out the check-boxes options on the right top of Odin, ensure that the ‘RE-PARTITION’ is unchecked, only the ‘AUTO-REBOOT and ‘F.RESET TIME’ checkboxes are both remained checked.

Step 4: Reboot your Galaxy Ace 2 into Download Mode
To reboot the Samsung Galaxy Ace 2 into download mode , you need to turn the power off. After it completely shut off, just press and hold the Volume Down key, Home button and the Power ON/OFF button simultaneously.

You should then prompted into a warning screen and asking you to press volume up if you want to continue or volume down to cancel, just simply press volume up to get into download mode. The download mode then displays an Android robot and say’s “Downloading.. Do not turn off target!!”

Step 5: Connect your Phone to PC or Laptop
Once you already reboot the phone in download mode, simply connect the phone to your PC or laptop USB.
In Odin window – the ID:COM box will turn to blue color and indicates the COM port number and a word “Added” on a log box will prompt you that the device is already detected or recognized by Odin.

Your COM port number might be different from mine. If you do not see a COM port number then there’s something missing or wrong. You may read again from the top of this post.

Step 6: Load the binary .tar.md5 file
Now, you need to just simply click on the PDA button, then browse to the folder where the .tar or .tar.md5 you have previously extracted and then select and load it.

Step 7: Start Flashing or Installing the stock ROM
Once if all set and ready to fire-up, hit the “START” button in Odin to begin flashing the stock ROM.
Do not ever interrupt the phone while already in flashing progress, like disconnecting the cable or turning off the device. Just wait until it completely finish.

Step 8: Watch out for the word PASS!!
When the Stock ROM installation successfully completes, you will then see a word “PASS” in Odin. This indicates that the flashing was already finish, and on the log box it says “All threads completed. (succeed 1 / failed 0)”. The phone will just then automatically reboot, then it’s to remove it from PC or laptop USB connection.

Confirm your fresh firmware installed by typing *#1234# or
Go to Settings>About Phone>Firmware info.
You can also do factory reset by dialing *2767*3855#.
Check and reconfigure your APN settings when data networks connection issues encountered. This only happens if you installed other regions stock ROM.
