Bare in mind, it's released for the Russian (CSC) SER.
Please follow the instruction bellow provided if you are willing to flash to your device.
Download Odin v3.13.1
Extract the firmware file you just downloaded. You should get 5 files:
AP (System &Recovery)
CP (Modem / Radio)
CSC_*** (Country / Region / Operator)
HOME_CSC_*** (Country / Region / Operator)
Add each file to it's respective field in Odin v3.13.1. Use CSC_*** if you want to do a clean flash or HOME_CSC_*** if you want to keep your apps and data.
Reboot your phone in Download / Odin mode (make sure your device is off) with the following button combo: POWER + VOLUME DOWN + VOLUME UP
Once in download mode, connect your phone to the PC, preferably using the original USB cable you got with your phone. Odin should detect your device and a BLUE box will show up with the COM port number. (Be sure, the SAMSUNG-drivers are installed on your PC!)
Do NOT tick any extra boxes. The only options to be ticked are F.Reset Time and Auto-Reboot.
Click the start button, wait for Odin to say 'PASS' in a GREEN box. Once the flash is complete, your phone will reboot, and you can disconnect your phone from the PC.
