• Secure boot status: Type: Samsung
• Security software version: MDF v1.0 Release 2

I have tried any and all 1 clicks i could find, attempted all old hacks i have from older root methods.

The only things i haven't tried are
• Exploits i did not find searching past 2 weeks every night for hours
• Anything that downgrades any software on phone
• Anything that installs custom recoveries

I am willing to downgrade and use an app like towelroot if it is possible, but with my firmware being from 2015, i'd be worried in following any downgrade methods (what few i have found for this phone) since none of them mention the ability to do it w/oa1.

to be honest, with such limited support for this phone in Google (especially since a 2015 kernel) I'm kind of scared doing anything major with it =/... I got the phone about 2 weeks ago, and have been trying to root it from day 1. The phone was a .99 phone from cricket to bribe me into staying with them( they just changed to GSM and screwed everyone over who had purchased a new phone recently, another story for a never to talk about time)

I would prefer to not trip Knox, but if it's a must then.... well... it's a must, isn't it...

any and all help would be highly appreciated.
