I have very minimal knowledge when it comes to Android development - I have never flashed a rom, but I have rooted my phone. Recently, I purchased an AT&T Note 3 from my little brother after he had tried his hand at modifying the phone. He rooted it, flashed Knoxraid, didn't like it, and wanted to revert - he removed root, kind of stupidly, before doing anything else. Now, the phone runs Knoxraid, but isn't rooted and I have been unable to get root again. What am I doing wrong, or what don't I understand?
Thank you all.
