A couple days ago, I deleted an important image from my T-Mobile Note 3 and I was freaking out, searching high and low for a solution. I read on Yahoo! answers to download DiskDigger, but the device must be rooted in order to install it. So, I tried to root my device with KINGO Root, which totally failed and then my device just went into bootloop and I thought I messed up my device for good. Luckily, on a different thread someone suggested to use the Youtube video GalaxyNote2Root made to unbrick my Note 3. (Even though it was for Note 2, it was the same concept and I did find the stock firmware on samsung-updates for my Note 3.) It ended up working successfully and then I continued to try root my Note 3 using Odin and the video instructions on xda forum (which I should have just done in the first place) and that worked successfully, too.
Now, my problem is, is when I went to update my Note 3 under settings, it says "Your device has been modified. Software updates are not available." I tried using Triangle Away (I don't know if I did it correctly) and also 1-click unrooting my device in SuperSU. I'm a huge noob at this rooting stuff, but what I gathered from all the research I did on Google, I apparently tripped "Knox". When I go into download mode it reads:
Current Binary: Samsung Official
System Status: Official
Knox Kernel Lock: 0x0
Knox Warranty Void: 0x1
So, a couple questions I have are, how do I "unmodify" my Note 3 so I can get updates? Is there a way to reset my Warranty Void back to 0x0? Will this always happen if I want to root my Note 3? Thanks in advance!
