Update Galaxy S Duos GT-S7566 to Android 4.0.4 ICS ZCAMD1 Official Firmware

Samsung Galaxy S Duos GT-S7566 (the version targeted at China) is the right pick for this tutorial, since it should offer an updated Android 4.0.4 Ice Cream Sandwich to transform the user experience into something that is even more attractive to the smartphone’s owners.


For now, let’s catch a glimpse into the requirements needed for every guide out there to work:

  • use a computer that has Windows (but, if its OS is Mac or Linux, then download and use a tool called CrossOver Utility);
  • turn on USB debugging;
  • create a backup via our tutorial, then make a backup of the internal memory to a dedicated hard drive;
  • use the fully unlocked S Duos S7566;
  • flash USB drivers (that work with this phone) on your notebook;
  • charge the battery of the handset.

Important instructions

  1. The party is ready to get started with step number one: the PC you employ for our tutorial needs to feature and Odin tool 3.07. Once that happens, you have to unzip them; the files which need to be extracted to the comp’s desktop are, among others, .tar.md5 and Odin3 v3.07.exe. Galaxy-S-Duos-GT-S7566
  2. Move on, next, to step two which goes something like this: power the GT-S7566 off and afterwards enter it in Download Mode. Usually, that is done in the following fashion: press and hold, at the same time though, Volume Up, Home and Power.
  3. Step three should deal with these tasks: run the Odin 3.07.exe as Admin by using the right click method on odin.exe and, when you’re done with this, click on “Run as administrator” (from the device’s context menu).
  4. Step four will need you to plug the handset to the laptop; you will be certain that the connection between the two has happened after you observe “Added!!” on the screen and a COM port colored yellow. Make sure you install, once more, the USB drivers for this S Duos S7566; or you can use some other USB port if the plugging doesn’t work.
  5. For the fifth step you will have to opt for a lineup consisting of various files that will only open up after you click on certain buttons. Here is how we do it: click on PDA and choose the file with CODE in its name, click on Phone and then opt for the file with MODEM in its name, click on CSC and afterwards be sure to select the file which boasts CSC in its name and click on PIT to have the .pit file opted for.
  6. The sixth step needs you to choose, as soon as you see them, two boxes whose names are F. Reset Time and Auto Reboot; there is another box called Repartition there, so opt for it only if you chose the .pit file earlier.
  7. [sc name=”banner-jos”]When you reach step seven you will be told to tap on Start. Now prepare for a bit of waiting, since the installation of the ZCAMD1 will commence. When the S Duos GT-S7566 is seen rebooting, you should understand that the flashing process is over. Disconnect the handset from your PC for step eight and also go to “About phone” where you should find the ZCAMD1 firmware.

Issues may happen to your phone, too, while you perform this tutorial. You can expect the device getting stuck in booting stage, so to solve this you have to do the following: for starters, go to the Recovery Mode. Then operate these: Factory reset/Wipe data and then a complete Wipe cache partition. Reboot the smartphone afterwards by choosing the system restarting option.
