you will need 7zip for windows or p7zip for linux to extract the items. you will need an unlocked bootloader to flash. if you have windows, run the flash-all-partitions.bat and follow the prompts. bat files in the folder are made by Mauronofrio on XDA. feel free to give him thanks. i personally made up a .sh file for linux users but i used contents from one of the .bat files from Mauronofrio.
