i am trying to get s-off so i can delete tempered flag and lock bootloader to get my phone back to stock. The only problem i have is that i can;t get s-off using rumrunner and after lots of tries i discover that i don't have a mainvar on my phone and i think that this could be the problem. Can someone tell me what can i do to get mainvar again ? here are my phone specifications:
