GPS stopped working well after Root & TopNTP

Hey everyone. I have and SM-N9005 on lollipop 5.0 build number LRX21V.N9005XXUGBOB6.

Now i rooted the phone and decided to see if I could get my gps to lock on faster with TopNTP app.
I think that after that my gps has had problems. It locks on really badly, or barely locks on to any satellites, doesn't know where i am with any precision.
When I use it for driving directions it doesn't follow me any more and only manages to update every 10 seconds or so catching up to where i am or even never managing to get a good position.

Now... What have I tried:
- Downloaded GPS Status, tried downloading AGPS data
- Reset TOPNTP to backup of original gps settings
- Reset through *#9009# of gps
- Even opened up the back of the phone to check that the cables were attached (they were) and lifted up the pins that attach the motherboard to the antennae just a little so that the connection would be stronger...

But nothing. It seems to get worse every day.

Is it something i f'd up with TopNTP? Is it the root? Is my hardware failing?
CAn anyone lend a hand?
Thanks in advance
