Samsung users can also back up data using Samsung Smart Switch to your computer. Smart Switch helps to move data across different Android devices i.e moving Samsung Galaxy S7 Edge backup data to Samsung Galaxy S8.
If you already have a custom recovery (ClockworkMod, TWRP etc.) installed on your phone, we strongly recommend a backup using that as it creates a complete image of your existing phone set up. [Tutorial: How to Backup Android Phone using TWRP]
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? Because, if your phone goes off suddenly while installing a custom ROM, flashing an official firmware update, rooting or installing mods etc. — your phone might get bricked or go dead permanently. No one wants that, right?
3. Most of the tutorials and how-to guides on Team Android are for factory unlocked Android phones and tablets. We recommend NOT to try our guides if your phone is locked to a carrier, unless we have specified the carrier name or device model.

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?
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
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.
so how would you go about doing a root then ?
NO root for Snapdragon processor PERIOD.. not yet,, maybe never..
following this guide, I´ve rooted my S8 G950FD and it´s working fine.
what custom recovery can I install..?
I am getting stuck on the recovery.img. It gets to about halfway and then says fail.
