Unhappy Phone directly boots into recovery...!!!!

i have lg p765 with unlocked bootloader (just yesterday). After rooting the phone I installed cwm recovery 6.0.1.9 by artas using recovery installer.
Now as kk roms work only on 6.0.4.x I tried to flash new recovery many times but after flashing new recovery phone directly boots into recovery after 2-3 seconds of LG logo. So I have to restore using my previous backup.
So even after unlocking the bootloader I am unable install roms.
Please help ... How to fix it?

Can anybody give me working recovery and how to use it ?(for my older recovery I had to press vol down button after blinking of lights)
