dm-verity corruption on reboot or boot up

Vortex

whenever I reboot or shut down and boot the phone again, it says something like this on the ANDROID ONE screen:

dm-verity corruption

This device can't be trusted, please press the power button to boot or the phone will power off in 5s.

when I press the power button the phone successfully boots up and works as intended for now, however, I have the February security patch update available, should I update it when it's giving such an error at start up?

and what does the error mean?

"Android 4.4 and higher supports Verified Boot through the optional device-mapper-verity (dm-verity) kernel feature, which provides transparent integrity checking of block devices. dm-verity helps prevent persistent rootkits that can hold onto root privileges and compromise devices."

Probably you have a corrupted filesystem. While several people got it corrected with a reset to factory defaults, if that does not fix it, your only option is to send it to repair.

Oh, Okay, but is it safe to update the phone? like will it break or something? that error doesn't really bother me, unless I can't update the phone.

Check it with nokia, you might end-up with a bricked phone.
