Important instructions

The following steps apply if you want to complete this guide.

  1. Download, on your comp, two files. Their names are as follows: Odin tool 1.85 and . Extract what’s inside them, then power the smartphone off.
  2. Simultaneously press and hold Home and Volume Down; when done, press Power. The logo of Android will appear and it will be followed by a triangle; after you press Power, the handset will have reached Download Mode. Now go and open, on the laptop, Odin tool.
  3. Plug the Galaxy S2 to the latter device, then have patience till the connection happens.
  4. Step four will need you to do the following: look for a couple of files that need to be flashed on the handset. Find out how to reach them below. Here we go:
    – a file with CODE in its name (once you click on PDA, you will see it);
    – a file which comes with MODEM in its title (it will make an appearance after you click on Phone);
    – a file whose name should include CSC in it (look for it as soon as you click on CSC);
    – a file named .pit (click on PIT to see it).
    There is nothing wrong with your device if you cannot see the files from above. When that happens, pretend you didn’t read about them, then check Auto Reboot and F. Reset Time instead.
  5. [sc name=”banner-jos”]Check Repartition, too, should you have seen the .pit file and chosen it.
  6. Click on Start, which will make the phone enter the installation phase. Once the update is on the phone, you have to wait for the device to restart.
