Smile No signal on paranoid rom last buid

Hi, im new on the forum in matters of posting, ive been using some of the roms you guys posted, some are very cool, others not so much, that just need a little bit of working.

anyways, im posting here to see if someone can help me, im using paranoid android lg p990 rom, i was on build number 3, and in the last build (build 5, old bootloader), i got a problem with my signal, i have everything working, except the signal, i check the baseband and it says that its "unknow", so i went back to build 3 and everything works fine. so is there anything that you guys can help me? i checked the rom, and looks awesome, but i cant use it as a daily =(

hope you guys can help me!

Regards.
