Default [Q] lg g2 D802 wont detect sim after kernel flash

Hello,

I tried flashing dorimanx'd kernel. But after that, my sim card doesnt get recognized (my brothers sim card does work in the my lg g2)

Do i need a new sim card? And what went wrong?

Btw. My phone was rooted and had TWRP installed.

(Sorry for my english, and please take note that im new to all this)
