Looking to

which I think it is similar to FasterGps already tried, I see that

**Not for usage on phones with android 4.2 or newer**

I do not see that information in XDA forum, where it seems do the same trick with NTP server in gps.conf

Another post

So I decided to change /system/buid.prop adding
dalvik.vm.execution-mode=int:fast
After reboot
shell@android:/ $ getprop dalvik.vm.execution-mode
int:fast
But it does not work ...

Another link in spanish
http://www.htcmania.com/showthread.php?t=650161
where there is a link to the following gps.conf

NTP_SERVER=es.pool.ntp.org
NTP_SERVER=0.es.pool.ntp.org
NTP_SERVER=1.es.pool.ntp.org
NTP_SERVER=2.es.pool.ntp org
NTP_SERVER=3.es.pool.ntp.org
NTP_SERVER=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 SUPL_HOST=supl.google.com
SUPL_PORT=7276
C2K_HOST=default
C2K_PORT=0
ENABLE_WIPER=1
INTERMEDIATE_POS=1
ACCURACY_THRES=5000
CURRENT_CARRIER=common
DEFAULT_AGPS_ENABLE=TRUE
DEFAULT_SSL_ENABLE=FALSE
DEFAULT_USER_PLANE=TRUE

After adb pushing this file and reboot ...  future tests in street.

Another app ... it allows to have the GPS search as a service permanently
