Have been looking for a way to root my Lenovo Yoga Pro Tab3 10. Here's how I did it. Thanks to the guys from xda-developers !
- Backup all personal data, as your device will be wiped and formatted completed
- Format a 4GB SD card and insert it
- download twrp-22.214.171.124(6)-x90-data-enabled.img.zip, and unzip it
