dm verity verification failed oneplus 3t

OnePlus 3T recently got the Android Nougat update. If you upgrade it to nougat, while you have installed a custom recovery or previously you had custom ROM. And somehow you tripped the verity check. It will give dm verity verification failed error at the startup of OnePlus 3T and in the recovery menu.

If you ever had TWRP or any custom ROM and it tripped dm verity check. Then you will see this error on startup. Everything was working fine with me after the update but this error was very annoying. After looking into this matter. I came across a number of solutions. The easiest and working solution is the one stated below. You don’t have to flash anything in this solution. You just have to get into fastboot and enter two lines of code, which I will explain in the guide below.

  • Make sure USB connection is set to File transfers.
  • Download and Install OnePlus 3T drivers on your Windows PC.
  • Download Minimal ADB Tool. Install it somewhere you can easily access on your computer. (It’s a great tool developed by the recognized developer of XDA. It has a number of features, we will be using it to enter fastboot commands)

  1. First of all, connect your OnePlus 3T to your PC using databcable.

Hi I am trying to download the latest software update in my OP 3T. It’s getting downloaded till 100% and then suddenly it says “signature verification failed” and goes back to 5 % again and start re-downloading the software. I have tried it thrice but same result every time. Do you think the above-mentioned approach would solve my help me out?
