Default [q] lg g2 wind mobile bricked d-801

Hi, I know this is for T-mobile but I will post my question here as Wind representative told me that they use T-Mobile devices

Earlier this morning, I noticed that there is the update for kitkat. I forgot that my phone was rooted with some chinese software, and I installed the update. Originally I planned to unroot the phone update but I forgot. Now whenever I start my phone I get the fast reboot screen. Is there anyway to fix this

Please speak in noob terms.... I am not very good with computer language.
