[Atrix 4G Q&A, Help & Troubleshooting] asmaron:
Hey there,

first I have to say - I'm new here - and yes, I have searched for my issue in this forum and elsewhere, but I didn't find a solution. So I decided to register here and ask you experts about helping me to fix my problem:

I'm on Epinters-Rom CM 10.1(Android 4.2) (26/08 Built) and having a problem with a fast GPS-Fix. Always when I use GPS the first time a day it lasts about 5-10Min to get a Sat-Fix. I have done some research about this problem and found this:

In a post on a german forum (I'm from Germany) for Defy Froyo and GPS bug I encountered that there are system files that contain specific configurations for GPS or direct downloading instructions of "ancillary data" (such as A-GPS Data). However, there are no configuration files with the name "location" in Epinters-Rom as they are mentioned in this thread, but I noticed a file in my system folder (system / ect / ) called "gps.config".

Doing more research about this file, I found a post here on XDA in epinters CM10.1 thread from August. Here is mentioned, that Epinters "gps.config" has no entry to an so called "NTP server. He made ​​this entry and now the GPS fix is quick. I didnt really see that Epinter commented this, but a year before, Epinter said (at another Rom) that the NTP server entry is no longer necessary (without further explanation).

Then I remembered (coming from Neutrino-Rom) that Neutrino has had an "GPS-Addon" that was separate flashable - a fix for every single country. So I looked at the the GPS addon of Neutrino (Germany) and behold: When flashing this GPS addon it seems, that just the "gps.config" will be fixed with the following entry for Germany:

NTP_SERVER de.pool.ntp.org
NTP_SERVER = 0.de.pool.ntp.org
NTP_SERVER = 1.de.pool.ntp.org
NTP_SERVER = 2.de.pool.ntp.org
NTP_SERVER = 3.de.pool.ntp.org
NTP_SERVER = 0.europe.pool.ntp.org
NTP_SERVER = 1.europe.pool.ntp.org
NTP_SERVER = 2.europe.pool.ntp.org
NTP_SERVER = 3.europe.pool.ntp.org

XTRA_SERVER_1 = http://xtra1.gpsonextra.net/xtra.bin
XTRA_SERVER_2 = http://xtra2.gpsonextra.net/xtra.bin
XTRA_SERVER_3 = http://xtra3.gpsonextra.net/xtra.bin

# DEBUG LEVELS : 0 - none , 1 - Error , 2 - Warning , 3 - Info
# 4 - Debug , 5 - Verbose
DEBUG_LEVEL = 0

# Intermediate position report , 1 = enable , 0 = disable
INTERMEDIATE_POS = 0

# Accuracy threshold for intermediate positions
# Less accurate positions are ignored , 0 for passing all positions
ACCURACY_THRES = 0

# Report supl ref location as position , 1 = enable , 0 = disable
REPORT_POSITION_USE_SUPL_REFLOC = 1

# Wiper ( wifi positioning ), 1 = enable , 0 = disable
ENABLE_WIPER = 1

# # # # # # # # # # # # # # # # # # # # # # # # # # # # # # # #
# # # # # AGPS server settings # # # # #

# FOR SUPL SUPPORT , set the Following Following
SUPL_HOST = supl.google.com
SUPL_PORT = 7276
SUPL_NO_SECURE_PORT = 3425
SUPL_SECURE_PORT = 7275
SUPL_TLS_HOST = FQDN
SUPL_TLS_CERT = / etc / SuplRootCert

# FOR C2K PDE SUPPORT , set the Following Following
C2K_HOST = c2k.pde.com
C2K_PORT = 1234

CURRENT_CARRIER = common
DEFAULT_AGPS_ENABLE = TRUE
DEFAULT_SSL_ENABLE = FALSE

# TRUE for " User Plane " , FALSE for " Control Plane "
DEFAULT_USER_PLANE = TRUE

In comparison to that, Epinters "gps.config" is only:

XTRA_SERVER_1 http://xtra1.gpsonextra.net/xtra.bin
XTRA_SERVER_2 = http://xtra2.gpsonextra.net/xtra.bin
XTRA_SERVER_3 = http://xtra3.gpsonextra.net/xtra.bin
SUPL_HOST = supl.google.com
SUPL_PORT = 7276

Do you think I could risk simply replace the two files? Or is it better to flash the file of neutrino? Or to edit the file by Epinter right? Or at least nothing at all? I do not even want to fabricate a Brick ... ;)

So you techies from this forum! Can you help me? :)

Thanks for reading this and sorry for my poor english... its not my native language! ;)

Regards,

Asmaron

PS: The Germany.zip in the appendix contains the files that would be flashed with neutrinos Rom (including the "gps.config"). The other single "gps.config.zip" is that of Epinters Rom. Simply open it in Editor/TextEdit or similar programs and you can see the above entries.
