  1. My Samsung Galaxy Tab A SM-T350 will connect to the Internet as long as I have it sitting right next to the router. However, if I am even 6″ away, it doesn’t work. Will this fix that issue? And is it possible to do all of that from the tablet instead of downloading it on a computer?

    • If you are confident about the Wi-Fi connection, Update to the latest version. In my knowledge, Root can’t enhance the Wi-Fi range of your mobile. Only Software fix by the manufacturers can do the process.

  2. It does not work on my Samsung Galaxy Tab A, SM-T350 Wifi, Nougat (gt58wifi).
    After installing the recommended TWRP, I could not boot into the recovery mode (volume up + power) but into normal mode.
    I tried many times with different websites but no success. I never see the team win display on my tablet.
    Can you help?
    Thanks a lot in advance.

    • You should Boot into TWRP after the first flash with ODIN. Or Else, you will lose the temporary TWRP. Also, If you didn’t flash the magisk in the first boot, you will lose root access. Did you get the “PASS” in ODIN?

      • I received a pass in ODIN, but I still cannot boot to TWRP. I tried re-flashing with ODIN, but no matter what stage I hold the buttons down at, it will not boot into the TWRP.

        • Un-tick the Auto-Reboot. After the flash press volume down+power to exit download mode. Immediately press Volume Up+Power to boot into recovery.
