Solve DM-Verity Warning on OnePlus 3

It seems that there are plenty of OnePlus 3 users who are complaining about facing the dm-verity warning when they try to flash/sideload stock rom or Custom Rom with TWRP recovery. Are you one of them too? Let me show you how easy is to solve this problem and what this warning’s presence means.

First of all, let’s clarify the fact that Verity is a security feature that was initially found in ChromeOS, designed to provide trustworthy computing devices, preventing malicious software from modifying a device. It was announced all the way back in Android 4.4 KitKat, but it passed almost unnoticed up to now.

Well, Google recently started to implement it strongly starting Android 6.0 and as you can guess, the purpose of this security measure is to prevent the software on a device from being modified without the user’s knowledge. If you do that all the time, chances are that rooting is no big deal for, but things are different for a regular user.

If you are rooted then you probably had used fastboot to unlock and flash TWRP on your OnePlus 3. This time we have to use fastboot mode again because you have to write two fastboot commands to fix this warning/error. Yes, this will easily help you get rid of the problem, so waste no more time!
