Samsung Galaxy S3 lte; GPS not working in stock ROM

[AC Question]

Hi,

I have a galaxy s3 lte phone and GPS worked in stock ROM, it also worked in custom ROMs (kitkat and lolipop), but when I flash the stock ROM back, the GPS doesn't work.
I flashed back a custom ROM (lolipop 5.1.1.) and GPS started working again but I need the stock ROM so i flashed it back to stock (kitkat 4.4.4.) and GPS stopped working again.
Any ideas what's wrong?

Thanks in advance!
