How to Root Nexus 6P on Nougat 7.0 NRD90U OTA and Disable Forced Encryption & dm-verity check

Avatar
  Update: Nexus 6P NRD90U build released. You can root and disable forced encryption on the newer build easily with TWRP recovery v3.0.2-2. Rooting instructions updated.

Android 7.0 Nougat is now officially available for the Nexus 6P and 5X. The update is currently being served as an OTA only, but factory images should arrive very soon.

Both Nexus 5X and Nexus 6P are getting Nougat update with build number NRD90M. And thankfully, rooting NRD90M is still the same as it was on the developer preview releases of Android N.

However, getting TWRP to work will be tricky once you install the Nougat OTA. It’s not because of Android Nougat update, but the dm-verity check and forced encryption on Nexus 6P that blocks TWRP 3.0.2-0 from booting on your device.

Thankfully though, we still have TWRP recovery version 2.8.7.0 for the Nexus 6P, using which you can sideload the SuperSU zip and get root access on Android Nougat 7.0 NRD90M update.
