Steps to Update Samsung Galaxy Star Pro to Android Lollipop 5.0.2
Plugin your Samsung Galaxy Star Pro to your computer via USB and copy the file you have just downloaded to the device’s SD card(not internal), do not extract the zip file.
Now Switch Off your device and reboot into recovery mode by pressing Volume Up+Power+Home key simultaneously until you see the boot logo on your device’s screen.
Now go to the recovery option and perform a full factory reset.
Now Wipe cache partition and wipe Dalvik cache (advance mode).
Now you can flash the ROM by selecting the option install from zip from SD card option which I believe is the simplest way. It will ask you to provide the zip file, browse the ROM file and hit enter to begin the installation.
It will take several minutes
Let the process to complete, don’t try to do much with your device at this stage until it shows “Thank You”.
Now, it will take some time to reboot. Have some patience and wait for it.
And you’re finished with upgrading to Lollipop, now enjoy the latest version of Android on your phone.
