[MOD] GPS Patch for Prime - Asus Eee Pad Transformer Prime

THIS IS ALREADY INCLUDED IN THE PRIME ICYLICIOUS ROM LOCATED HERE
THIS IS NOT A FIX FOR FAULTY HARDWARE!
Attached at the bottom of this post is a CWM flashable file to help with the known GPS issues with our beloved Prime.
When creating my ROM, I noticed that Asus had left out the gps.conf file completely from the ROM, which exists in every other Android ROM I've come across.
In the zip file is a tweaked "gps.conf" and a tweaked "SuplRootCert".
Directions are as follows.
Download the zip file from the attachments in this post.
Boot into CWM
Clear Cache and Dalvik Cache before flashing (your first boot after clearing will be longer than normal)
Flash file in CWM, and reboot.
To calibrate your GPS download GPS STATUS, install and open. Go into settings, "Display and Tools"....tick "keep screen on". Go into "tools" click "compass calibration" and follow instructions. Once calibrated go outside in an area clear of obstructions. Make sure GPS is turned on in "settings". Start up GPS status and let it sit for a few minutes (if GPS icon does not start blinking, click on your quicksettings to bring up the quicksettings bar, then click on the GPS Status app screen). First time starting the GPS will take a few minutes to lock. After they're acquired, your GPS should lock quicker the next time you start your GPS.
These are my results from THIS THREAD following the directions listed above.

If you're not in the USA, you can find the files you need HERE, but you'll have to manually extract the files from the zip, and copy them into the appropriate directories!

Asus uses /etc/gps/gpsconfig.xml
you reference the android gps.conf, which i think was a android3.x default, and no longer comes with ICS.
with gps.conf you get a lock based on wifi+internet time, and not actual hardware gps, which the gps/gpsconfig.xml is for.
so gps.conf virtually just looks good, because you previously activated hardware GPS at your home with internet connected. This will not help if you have no wifi available, or if its an unknown AP.
gps.conf is just a false hope for hardware improvement, but is pure internet data based.

Actually Dexter gps.conf does still come in ICS. All the Acer builds still have it in there.
First time on stock without the fix, no lock, afterwards...10/13
EDIT: and both Asus and Acer use the gpsconfig.xml

Am curious. You took your TF Prime, outside, and actually tested this?
Because frankly, the fixes you posted, really didn't do a lot of improvement. Especially in the EU region.
Or is this theory?

i took mine to a train station with out wifi, and no lock in first 10mins
gps.conf is a quick lock based on wifi and known internet AP routers, so it can point out your coordinates, not a hardware gps fix.
but yes, it can help in wifi-lock if wifi is also achieved, i do not deny that from here, but its not fixing any asus hardware issue.

Uploading a video right now. Never said it fixed any hardware issue Dexter, just that Asus had left out files that EVERYONE else is still using even in ICS, along with the cert file we've been using for a long time with the A500. Moscow said he thought you might have been the one to come up with the cert file...is that true? If so, my apologies for not giving you recognition.

Was this a cold start up??, did you wipe any cache and all that stuff, so nobody will second guess ya
I tested it myself with your rom and I did get a lock much quicker than the stock rom and Virtuous rom as well.

I actually had to reboot just before the test. no wiping of anything, but of course that's already included in my ROM, so you might want to wipe dalvik, and cache if you're using it with another ROM, as that might help
EDIT: have modified the instructions, and thanks for pointing that out.

yeah the video looks official. those sat's locked quick as a mofo. well you know the next proof people going to want to see. actually driving and seeing if satellites can lock and hold the lock for navigation purposes like in Google earth or whatever.
seems legit. hopefully this is a viable fix and can be improved on further down the road.

Like Dexter pointed out, this doesn't fix any hardware issues. All I did was put a tweaked version of the file that Asus should have put there in there, and added the cert file that most don't include.

Unfortunately this didn't help my prime (my hardware is probably beyond software rwpaies) but thanks for putting this out there!

I just got my Prime, do you think they've improved/changed the hardware since the first release?
I do know when I first got my OTA for ICS as soon as I booted up for the first time the GPS wouldn't lock to save it's life.
Just wondering out loud ...

he he like the OP states...it's not a hardware fix, but it should help acquire locks faster than stock.

Glad you're having success with it bro!

If this is 2 tweaked files why can't we download unzip & place the 2 files with Root Explorer & bypass the whole flashing process if your only rooted? See any issues with this?
If not what are the directory paths for each?

Yes, this should work as well.
