What is DM-Verity?

Before heading the solution, let us first try to understand the problem first. Verity is a security feature, originally found in ChromeOS, designed to provide assured and trustworthy computing devices, preventing malicious software from modifying a device. It was announced all the way back in Android 4.4 KitKat, but, no one really seemed to care about it until recently when Google started to implement it strongly starting Android 6.0.

Above screenshots show a typical dm-verity warning. The primary purpose of this security measure is to prevent the software on a device from being modified without the user’s knowledge. If you are a flashaholic, then rooting is no big deal for you because you do it all the time. But for an average user, it is a big deal.

With Verity in place, any changes made to the system partition will be detected on boot. So if you have recently made any changes to your system partition, then you’d probably see one of the messages displayed above. While this very good for non-geeky Android users, it is not a very good news for people who aspire to root their phone in future. Google might crack down hard on rooting methods in a not so distant feature.

Do let us know if this method worked for you (or even if it didn’t). Any problems with the procedure or need any help? Drop a comment below, and we’ll do what we can to get the issue resolved for you.


  1. Wiped you said did you wipe it from TWRP or just did a factory reset from the phone settings?

  2. Oneplus patched fastboot in their latest version so that command is no longer valid. The only way is to downgrade to OOS 4.0.3 and remove dm verity then upgrade again, OR just wipe the phone and it goes away. I just wiped it and now I don’t have a problem.

  3. i’m also facing the same problem sir will you please help me out!!. Actually am a usual user i dont have much knowledge. so please explain me in step by step process so that i can remove dm verity problem

  4. You can still use this method. Just downgrade your device to OOS 4.0.3 and then try it. It’ll work!

  5. Nah actually I figured it out. OP patched their bootloader and removed the command bc it’s a security flaw. Which, I agree haha. Oh well.

  6. Nope. When I run the disable or enable verity command from Fastboot I get a “FAILED (remote: unknown command). Any ideas?
