N910A DM verification failed

I have 5.1.1 firmware with 4 files so i flash this phone with these files after that it was restart on updating apps 12 out of 145
On recovery mode it say DM verification failed
Wipe data and cache after flash not solved
I flash it without CSC file because it contains cache.img which cause this issue and immediately go to recovery there is no dm verification failed error but when boot the phone it was restart on updating apps and this error comes on recovery
What is the problem please help me
