What does it do : It will change/create your "gps.conf" file, so your phone will connect with the Nokia NTP Servers in Europe instead of Google. You should get a faster GPS fix.
Installation : apply zip in CWM Recovery
For which ROM´s : All
All NTP Servers listed here, you can edit "gps.conf" and change the server with your prefered one : http://www.pool.ntp.org/en/
Hidden menu fix : use nokia servers & avtivate SLP Auto Provision
all credits to conceptics @ modaco !!
To get it to work as flawless I have made the following adjustments that seem to work well:
1. Go into the LG hidden menu
2. Go into GPS Test
3. Go into System Settings
4. MOLR Protocol (is set to User-Plane)
5. SULP Setting -> SLP Server Setting, I created a new one for the nokia servers (slp address: supl.nokia.com, port: 7275, no cert and no TLS setting)
6. SLP Auto Provision is activated
I'm in Switzerland and with this settings (supl.nokia.com), the GPS fix is relatively quick and works consistently within about 10 seconds of starting Google-Maps.
Still not sure if this is indeed FR15 related or if the problem is purely SSL Certificate related. If it is SSL Certificate related wouldn't the problem be much more widespread and wouldn't google already have updated the certificate by now?
Anyway, hope the above works at least as a temporary workaround.
access hidden menu :
In launcher pro you just press and hold on one of the home screens until a menu shows up.
Select "Shortcuts" then choose "Activities" scroll down until you find com.lge.hiddenmenu.
tap on it then tap on HiddenMenu. now you have a shortcut on the home screen.
if you have cooked ROM without hidden menu, you can use my zip to install in recovery first :
