I always get confused with King Root and Kingo Root. One is generally okay and the other has some questions about it's security and/or effectiveness. In either case, I don't think either root by replacing or modifying any system files, but use known exploits for that particular version of Android.Your firmware can be found at <a href='https://www.sammobile.com/firmwares/database/SGH-T399N/' target='_blank' class='externalLink'>https://www.sammobile.com/firmwares/database/SGH-T399N/</a>There are two versions listed. I couldn't tell you what the difference is but the later version probably has a specific T-Mobile feature or patch already included. The instructions to flash are right there on the download page.Just so you know, if you choose the "regular" download, it will be a throttled connection and download very slowly. It's the same file as the fast download but you don't have to pay for the privilege. <img src='styles/smilies/google/smilie.png' class='mceSmilie' alt='' title='Smile
Pls can you suggest for which particular one i can use to root my phone (Huawei Y6 Pro, TIT-U02)
