A few more optional tips that you should remember:

1. Having problems connecting your Android phone to the computer? You need to enable USB debugging mode. See here: How to Enable USB Debugging — for Gingerbread, Ice Cream Sandwich, Jelly Bean, KitKat, Lollipop, Marshmallow and Nougat.

2. Make sure your Android device is charged up to 80-85% battery level. This might help you: How to Check Battery Percentage. Why?

  1. This lists the SM-G950W/U and provides files for both, but both those devices (Canadian and US variants) have locked bootloaders – they only came with the Snap Dragon 835 (not Exynos). Using this will probably just brick your device. I’m not sure why those model numbers are even listed when there’s no BL unlock yet. Has someone actually tested this?

  2. Hi, I’m struck at SetupConnection. I tried changing USB ports and used only the cable that came with the S8 but process will not move pass SetupConnection.

    Any idea? Thanks

  3. This only works if your bootloader is already unlocked. Your bootloader is not unlocked if you have the Snapdragon 835 – only the Exynos. No one in the USA or Canada got the unlocked bootloader unless they ordered it from overseas. This does not work on the SM-950U/W.

  4. following this guide, I´ve rooted my S8 G950FD and it´s working fine.
    what custom recovery can I install..?
