[Upgrading, Modifying and Unlocking] Grancapitan:
SOFTWARE

1-You have to be ROOT, without that the most important and significant modifications of this manual may not be done.

2-can come in handy, but in my case it was not necessary, install these 2 apps the Play Store:

A-Mt gps epo fix, to download the files EPO.

B-Gps test to see which satellites are caught, and if that does not catch in 1 minute: enter settings, activate the 1st box is disabled and give CLEAR UPDATE AGPS AGPS and then, usually works in cases where no "start" to catch the satellites.

3- That upload file to version 4 is only copy and replace previous copy of the original gps.conf, gps.conf content that is in system/etc.

Not upload. New gps.conf for insert:
