The flashing process WILL WIPE your already installed apps.(Backup first)
NOTE : IF YOU NEED BIGGER DATA SPACE PLEASE DO THE FOLLOWING:
GO to : Settings>>Storage>>(you will see "Default Write Disk") >> select External Storage.
This will make your External SDCard becomes your internal SDCard (sdcard0). and I recommend you use 32Gb (class 10) SDCard but please check your already installed apps as they might become "uninstall" and you will have to reinstall them .So now your internal data storage has become 32Gb instead of 8GB.
The S017 ROM must be installed via TWRP recovery there and instructions on how to install TWRP either through flashing using SPFlashTool or using MobileUncleTool is given in the instructions sheet.
First you must already obtain root access to upgrade – if you are are not rooted and on stock ROM you must gain temporary root access by using VROOT (which is to be installed on PC and will Root the phone via USB connection- or RootMaster to be installed on phone) this will enable you to use MobileUncleTool or RASHR Recovery flasher to install TWRP recovery.
Copy the zip file on the external sdcard and go into TWRP. choose INSTALL, select this zip file.

DO NOT use MobileUncleTool/Faster GPS/GPS Doctor apps to change the gps.settings. you only have to edit your locale in the file called "gps.conf" in system/etc folder.
