No-verity-opt-encrypt sounds technical, right? Well, it is technical. With the increasing number of Android devices in the market, some users want to root their device to customise it according to their own needs and get access to everything available in the Android ecosystem, including new feature updates via a custom ROM. One way of getting this access is through rooting the device and installing a custom ROM on the smartphones.

While users want this access, OEMs are always trying to secure their device’s ROMs and associated software by restricting user access for rooting the device.

Companies continuously work to improve the security of devices by using a security mechanism such as Dm-verity that restricts any alterations in the system. All the smartphones manufactured by top companies such as OnePlus, Samsung, Xiaomi and several others have their ROMs secured so that a user can’t alter or play with the phone.

What is dm-verity?

Device Mapper Variety is a security mechanism used by OEMs in their devices to restrict the actions of rootkits so that a device can not be modified. The latest devices running new OS versions goes a step further by not allowing the booting process through the optional dm-verity kernel.

But as with every other problem, there is a solution, and one of them is no-verity-opt-encrypt, a boot data encrypter that helps in flashing TWRP when dm-verity is enabled, without potentially damaging the device.
