Third post in the thread below. Just get the 7.1.2 full image instead of the 7.1.1 I mention in that post.

Pay attention to removing the -w from the flashall bat file. That is the key to saving your data.

And second to the last post in the thread are the​ instructions for getting root back.

I'm on a mac, not sure how to do the last step with running the .bat file

Edit: went into the bat file and ran the equivalent commands in terminal
(fastboot flash bootloader bootloader-marlin-8996-012001-1702151126.img
fastboot reboot-bootloader
ping -n 5 127.0.0.1 >nul
fastboot flash radio radio-marlin-8996-012901-1702171013.img
fastboot reboot-bootloader
ping -n 5 127.0.0.1 >nul
fastboot update image-marlin-n2g47e.zip)

Here is the terminal messages I got
