[FIX][GPS]Slow GPS fix for EB 1.04 Froyo and GB - Update 5-25

[kev0153]

I wouldn't call myself a developer by any means and MODS, if this thread is in the wrong forum please delete or move.

When I upgraded to 1.04 EB Froyo version, I noticed that the GPS lock was a little slow. It reminded me of the old HD2 when I installed android on it. There was some great work done to write a GPS.conf file that speeds up the lock. Out of curiosity I dug up the thread on the HD2 android forum and gave it a try.

Some people are having some luck with Gingerbread as well.

The thread is here.

The original FTP site these were hosted on has some uptime problems. Here are the latest V1.2 files for the USA here. See the original thread for an explanation for the regions. These files were setup to flash on the HD2. I wouldn't try flashing them to the G2x. Extract the gps.conf file and install by hand using Root Exporler. Change the owner, group and permissions to match the rest of the files in the folder. The gps.conf file goes in the system/etc folder

See the link above for an explanation on the regions

Change permission to this

Owner: Read Write
Group: Read
Others: Read

owner and group are both root

Hawaii
NESE
North East
North Mid State
North West
South East
South Mid State
South West

I've also made some files that will flash correctly to our G2x. I've tested the South West and it works. I'm running the Froyo version of EB 1.04, it should work on other versions but make a backup just in case. No need to mess with permissions or group or owners with this method. Just flash and go.

Hawaii G2x cwm
NESE G2x cwm
NorthMidState G2x cwm
SouthEast G2x cwm
SouthWest G2x cwm
NorthEast G2x cwm
NorthWest G2x cwm
SouthMidSate G2x cwm
Canada G2x cwm


It does seem to speed up the gps lock. With a cold start, I was getting near instant lock after a few seconds, inside on a cloudy day.

I believe that the files is optimized for t-mobile networks but read the thread.

So passing along this tip. Let me know your results.

Thanks

I've only had it a couple hours, but have tested it several times. I've tried a couple ROMs, resets, and this tip a couple dozen times. This seems to be the only thing that's made my GPS actually reliable and work when I want it to.

Stock, .conf file for northeast

Change owner and permissions to match the rest of the files.

What exactly needs to be changed in the file to match? And where does it go?

I can't find the gps.conf in /etc/ or /system/etc.

Did you just dropped it there or do we need to change the name of the file to something else

Using root explorer long click on the file and change owner and group to root. Change the permissions to RW_R_R no execute for any owner/group and read-write for the root owner/group

It doesn't exist in this ROM you have to add it. Go to the link I posted and find what appropriate region and download the zip. Unzip it and find the gps.conf. Push it to your /etc or copy it using root explorer.

Maybe I'm retarded but I clicked on the link that says Xda members click here and it takes me to a website without any download links

Looks like the site might be down. I think he said that is his personal ftp site. We might have crashed it. I'll pm him to see what's up.

The link works fine for me. Goes to an index with two folders "eugps" and "usgps". Inside "usgps" is two more folders, "USGPS 1.1" and "USGPS 1.2". Inside 1.2 is the various regions US regions.

yeah seems to be up now. Like I said, I think it is a small/personal server. If it acts up try coming back later. I'll PM the developer and see if he is interested in a mirror.

Click on the large "XDA Members Click Here"

Thought maybe it was a browser thing, not showing up as an ftp index. Tried in many of them, mac & pc, worked everytime.

Don't mind uploading any, but it looks like kev beat me to it.
