Default Can I flash back to vs98012b 4.2.2 from vs98024a kitkat

LG G2 vs98024a kitkat rooted stock Rom with twrp recovery is what I'm running & I'm unhappy with the kitkat OTA & wanted to know if I can flash back to OTA vs98012b debloated? Could I do it via twrp or flasify? Do I just wipe cache & delvik cache or more? Or is it possible at all? Some advice would be very much appreciated thank you...
