Why isn't my android working properly?
It's possible that the flash purely failed, or that you dirty flashed (flashing without clearing the cache/data) the ROM.

Seeing as you have access to recovery:


I'd suggest that you download a new CM ROM (Lollipop-5.0.2) from the XDA Developer Forums
Download the corresponding Google Apps package (i.e. for PA GApps for Android L)
Place both of the .zip files on your external SD card
Boot your phone into recovery mode and Wipe Data (Factory Reset). Also wipe all caches (Dalvik inclusively)
Install both .zips. First the ROM, and then the GApps package
Wipe the Dalvik Cache one more time for good measure
Boot the device and enjoy CM
