GPS SOLUTION FOUND updated 5.4.11

---

The best GPS solution that will stablize your gps and fix issues can be found here, but please read all
http://forum.xda-developers.com/show....php?t=1068416

Change GPS server:
Video instructions/much easier!
New HD video here:
http://www.youtube.com/watch?v=KLnn1...e_gdata_player


Root required*
United states only*
Other countrys:
You can still find a server for other counrties, but watch my youtube video first on how to. Even states from
https://support.ntp.org/bin/view/Ser...OneTimeServers
Once you find a server copy and paste server were It says in instructions: us.pool.ntp.org.

Instructions: With Root Explorer go to /etc/gps.conf

In Root Explorer long press on the file and select open in text editor

Change the first line from: NTP_SERVER=north-america.pool.ntp.org to NTP_SERVER=us.pool.ntp.org

Save changes and reboot

ENJOY

Thanks to UnicornKaz, calebv2 and mrvanes from xda devs.

FYI STOP USING FASTERFIX APP IT WILL SCREW YOU UP IF YOU APPLY THESE CHANGES

POSTED BY UnicornKaz

"Settings-->>Location & security" menu, there is the option to "uncheck" how the device determine your location...etc

1/ Use wireless networks
2/ Use GPS satellites
3/ Use location for Google Search

I have #2 & #3 checked

and I leaved #1 UNCHECKED

lost

wrong file, its gps.conf

We went thru exactly the same stugg with the Ssamsung

Galaxy Vibrant.

Nothing got better until we got more advanced leaked modems on XDA.

Wow!!!!
Just did the mod and in my house the tablet got a GPS fix in 14 seconds. My phone can't get a fix at all indoors.

Instructions: With Root Explorer (or similar app) go to /etc/gps.conf

In Root Explorer long press on the file and select open in text editor

Change the first line from: NTP_SERVER=north-america.pool.ntp.org to NTP_SERVER=us.pool.ntp.org

Save changes and reboot

ENJOY

Thanks to calebv2 from xda devs.

FYI STOP USING FASTERFIX APP IT WILL SCREW YOU UP IF YOU APPLY THESE CHANGES

worked for me, excellent tip, also unloaded fasterfix and disabled wifi location, google maps lock within a minute.......

do this mod works in US only or everywhere?

USA only.......................

You should try fasterfix on the market where you are. I have no idea what Bali would use for gps server...

you need root explorer or another editor that can mount r/w
