According to adilrenzu's guide here we are now able to root Lenovo K6 Note successflully. This guide is for users who want to change their phones to the factory original state, downgrade from 7.0 or unroot. I tested this with my lenovo k6 note. Bu as you know rooting and unrooting operations are dangerous and may brick your phone. Please do it with your own risk.

This downgrade process supports full OTA Upgrade.

I've reached that stage, what should I answer to the questions about :
1. Restore original boot.img
2. Restore original recovery.img

I'm guessing a "NO" would be safer since they were modified and we're restoring anyway...ok did that.

Sorry what ? I'm pretty sure I got that date from Lenovo's site, let's see, yes : https://support.lenovo.com/fr/en/sol...0ay#smartphone

"Lenovo VIBE K6 Note Android 6.0 Marshmallow Android 7.0 Nougat May-17 Pending"

Quick question, do you see any problem in flashing the recovery.img from your 5_K53_S123_170216_ROW_STOCK.rar ? I've just found out that you could easily remove the password locks by booting into TWRP and that's making me a bit nervous. Thanks !

No not tested. Not using phone locked. I tested the xposed and modules only.
