problem with replacing gps.conf
I hope this is the write location for my post.
I have a HTC ONE rooted, android 4.3
I have a problem with my GPS: it doesn't lock any satellite. Reading on forum, I found that the problem may be the setting of gps.conf file in /system/etc.
In fact, checking it, I found that the NTP_SERVER set was for north.america, while I'm in Europe.
I would like to modify or replace it, but I'm experiencing some problem. Using Root Browser it seems to be able to modify it, but after rebooting the device it is exactly the same before the editing. I tried using other editors as ES File Explorer, but when I try to modify the file, it says "read only file system".
It makes me thing that also the other editor is not able to modify the file, since after reboot it is actually un-edited.
What do you think? how can I actually write in file system and actually modify gps.conf?
Thank you in advance
Let me add another detail: I tried to create a new empty file in the same folder with Root Browser. It seems to be able to create it, but after rebooting the device it desappears..so I guess I actually can't modify/write in the file system..
