32Disable encryption and dm-verity
33We need to disable force encryption of data partition, to read user data. Disable dm-verity, which is a kernel feature to check the integrity of boot image. Flashing the zip file mentioned in Instruction section, allows user to also enable or disable disk quota, that grants the system to get storage statistics faster and it should even improve system stability, necessarily it don’t have to be disabled.
