Lenovo Yoga Book Android 6.0 ROM: androidfilehost.com/?fid=817550096634799507
Intel Flash Utility: 01.org/android-ia/downloads/intel-platform-flash-tool-lite
Custom Recovery: twrp.me/lenovo/lenovoyt_x703f.html
Magisk Root: magiskmanager.com


Flashing ROM

With the yoga book in recovery, either use the intel utility + json files to flash, or these commands to flash with adb tools with the files from the archive. To unlock bootloader, enable dev mode, then settings>developer>oem unlock.

Fastboot Flashing Commands:
fastboot flashing unlock
fastboot flash gpt gpt.bin
fastboot erase misc
fastboot erase persistent
fastboot erase frp
fastboot erase metadata
fastboot format config
fastboot format country
fastboot format cache
fastboot format data
fastboot format factory
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash config config.img
fastboot flash country country.img
fastboot flash system system.img
fastboot flash bootloader bootloader
fastboot flash oemvars bootloader_policy-oemvars.txt
fastboot flashing lock
fastboot continue
Set Country Code
how to make Halo Keyboard work. Go into Contacts and create a random one, then type into search ####6020# then set country code. This also fixes the "easyimage-country code" error which causes OTA updates to fail. During your system setup process, if you get constant touchpal errors, go into system settings and disable Touchpal app.

OTA Updates
You should now be able to run thru 5+ OTA updates for a few hours till you're at 7.1. These require a locked boot. If you unlock it, then everytime there's a new update you'll have to unroot and relock.

Root
Download twrp and magisk from the above links
$ fastboot flashing unlock
$ fastboot flash recovery twrp.img
go into advanced sideload
$ adb sideload magisk.zip

To get a full Linux desktop experience with chrome with extensions and dev tools, I recommend the "Linux Deploy" and "Xserver" app to install Ubuntu desktop.
