Unhappy lost recovery after OTA update, please help!

I installed this rom on my phone:

[ROM] 4.4.2 GPE, philz recovery, fixed logo, easy for noobs and no noobs

I have failed to read a warning not to update rom via OTA. I updated via OTA to 4.4.4. As a result, I lost the recovery.
How do I regain the recovery?

I tried flashing the stock recovery and then CWM over it and it didn't help.

Please help.
