Cyanogenmod updates break functionality

When i install some cm nightlies my device becomes unuseable. Do i have to do every update in order? I have my tab at 4.4.4 and i updated to 5.1 and i keep getting pop ups of apps crashing to the point where i cant do anything. They pop up about every half second. I get com.google.process.gapps has stopped working as well as email, gmail, google play services, etc. I installed lollipop gapps and it still happened. Ive had the same problem on my s5. How can i update without this happening?

lens break

Well that didn't take long for me to completely shatter the glass covering the camera lens. Oops. 175 replacement for me I guess.

Soft break, /cache mount problem with locked bootloader

I breaked my Nexus 5 by restarting it while clearing the cache. I cannot use `fastboot flash cache` since I have locked bootloader using BootUnlocker. I have CM12.1 with CM recovery installed. Is there any way to unlock the bootloader using CM recovery or fix the cache partition without oem unlock?

If you have SM-G900V and don't have debrick.img you can create your own one by:
Use Unbrick-Creator.zip
