Jailbreak Central - The Best Jailbreak Forum!

My IPhone 6+ recently has been ICloud activation locked. It is locked because I found the phone on a local online market place for free. so I decided to pick up the broken phone for free and fix it. After cosmetic damage was fixed I found out that the user decided to lock the phone. I now have a phone I paid 120 dollars to repair setting on my desk as a paper weight. After doing some research and thinking I thought that jail breaking the phone would be my only way in. I have recently downloaded Ubuntu to my 64x Windows computer. I also have checkra1n installed and set up. But when I go into the terminal and hit start follow the on screen instructions it starts to jailbreak. Codes of white text fly through my screen until the terminal says it has finished don't unplug your phone. But when my phone starts up it just boots back to the hello screen. I do not know if I am missing something since this is my first time jail breaking ios. If you need any more info just ask I am really hoping I can get into this sucker. ( sorry for all the information the story could have been shorter but i want to proof I am not a thief and I am actually trying to get into this phone to use it not sell it).

My IOS is running 12.4
HAPPY VALENTINES DAY
Thank you
