  1. I have followed every single one of your instruction and worked perfectly until the Flashing the modified AP file in ODIN v3.14
    It won’t flash…
    Added!!
    Odin engine v(ID:3.1401)..
    single download.
    magisk_patched.img
    it got to that part and just stuck there for about 2 Minutes. I think I messed something up and then decided to press Volume Down + Power to cancel the download…
    Do you have any suggestions?

    • If you are confident, you are flashing the correct patched .tar file, Try again. Sometimes it can happen—Run ODIN as Administrator.

    • I was also getting the same error as you. Just rename the “magisk_patched.img” to “boot.img” and then convert it to a tar file. It worked for me.

      I hope this will work for you

    • We will try our best. But currently, we can’t assure you. If you have any doubts about the guide we are happy to help you.

  2. Hi, I tried flashing TWRP in my Samsung galaxy m20 device, but I stuck in the boot loop, and it’s not even booting into recovery mode and download mode. When I’m charging my device, it keeps on boot looping help me to get out of it. Once I boot into the recovery mode or download mode, I can fix this, but I can get out of this.

    • Press the Power Button for 10-15 seconds. When it foes off, Try to boot into recovery and wipe user data. You should check that you flash the correct file or not.
