[FIX] JVP GPS fix - work in progress

First things first, we use agpsd(/system/bin/) & not gpsd(/system/vendor/bin/)
so for anyone compiling a kernel will need to modify their init.rc:
Code:
#service gpsd /system/vendor/bin/launch_gps.sh
# socket gps seqpacket 0660 gps system
# user gps
# group system inet
# +STE GPS Daemon
#GPS_CHIPSET_STE_CG2900
service agpsd /system/bin/agpsd
user system
group system inet
oneshot
Everyone please thank cmenard for being amazing & quick to provide us with a magnificent JVP kernel with GPS support .
These files should work on any Gingerbread, but I've packaged this with a JVP kernel so be warned. I'm going to try and see if I can get it working with just init.d support or something later.
Alright guys, I couldn't get it to lock again, but we're close. It is running in the background but it's not quite locking. Something is off. I will dig into it more later tonight but I gotta run. If anyone smarter than me can figure it out, I'm posting what I have. I believe it's a permission issue somewhere.

REMEMBER, the kernel is for JVP ONLY. It's included in the flashable zip
The issue
If you turn your phone on with GPS enabled, it will find a lock great! However, if you turn GPS off & back on GPS never starts back up.

you are amazing!!!
its a good start
those useless fools at samsung should be fired

Samsung is the one wrote the drivers for the Galaxy S 4G's gps. We're just lucky that it seems to work on Vibrant too.

People are a little annoyed that it took so long. Not to mention that we get a leak for sgs4g, and not the vibrant. But hey this means I get to get back to flashing like mad again..... I hope.... lol
Finally going to try a GB rom soon on my phone..... woooohooooo lol

awesome!! looking forward to see progress on this!! i hate my gps!!

Got it to lock almost instantly by turning off xtra in angry GPS... more testing to be done

Wait so this could potentially work with CM7?

What about gingerbread battery drain? Not taking anything away from the gps fix...

With the JVP build that Birgertime made for us, I haven't had ANY battery drain. Hell, GB actually uses less battery for me then Froyo, it's kinda shocking lol.

Battery drain is a NON-ISSUE on 2.3.4/JVP.

I can't wait for a GB that's tweaked by EDT plus not needing to flash a bootloader. A leak for the vibrant would make a lot of difference.

Honestly? Flashing the bootloader was relatively painless. Getting recovery working after that was painful, but I think that's something I did wrong with the kernel (still not sure what)... But as long as your computer doesn't decide to go blue-screenie mid flash, I don't see how you can mess up the bootloader process.
I switched to JVP yesterday myself and the battery has been great. It's almost time to welcome our Gingerbread overlords. Now, the question is - Does this leak bode well for WiFi Calling on GB?

delete the angrygps.apk!!!! 8 locks instantly after doing so. Birger better get a million thanks since ALL of you are gonna use this.
edit - dont.delete. rename .bak and then undo.

Haha! Such a noob. Everyone knows about this issue. Read before you post.
You think you use GPS a lot. I do Geocaching and requires a higher accuracy than driving.

If thats the case, i think you'll find the 7.x.x series or 2.3.3 will be of higher accuracy

I also have problems with GPS. However it also seems my compass is not exactly correct and unstable. There seems to be some correlation. How accurate is your compass?

Haven't tested compass yet.
Progress with gps testing:
Tried several radios without wiping the cache first (no help with gps, wifi&data ok)
Now using nexus radio kb3, seems to work , have to test some more
KB3 (and KF1) also fixed the "always roaming" problem.
To get kb3 to function, had to (wipe cache +)flash kf1 first, reboot, (wipe cache+) flash kb3
At this point, the key for successful gps is to wipe cache prior flashing radio (modem)

Hi, tried your way also but no luck so far. Still think that the compass is of influence. Sometimes GPS works and then suddenly compass becomes unstable and is deviating and at the same time the GPS looses fix but still has satellites in view. I am getting desperate. will try some more.
Btw I am on titanium rom

ok, too bad . I'm not totally satisfied in the way things work just now but at least i can drive with waze on for 10km (the longest i drove today). Tomorrow more test while driving to the cottage almost 300km away.
I have had it working on some older versions of ics roms, but really don't want to go back there..

Try JVK,JVT,JW4,JVU modems (from Rom Manager it's easy)
Toivottavasti joku noista toimii kunnol myös gps:s!
Muute, lisää mut google talkis [email protected]

Tried. Only with some luck.. GPS gets fix, keeps it for a while then loses fix and doesn't seem to get it back. Sigh.
Think I'm going totally stock or Darky's and test there. And then if things work like they used to, come back to ICS roms.
Sent from my GT-I9000 using Tapatalk 2

I'm getting good results with JVT. GPS locks pretty well( tested on bus yesterday).
Sent from my GT-I9000 using XDA

All modems worked as badly.
Then I changed kernel to semaphore and was able to drive 160 km with only few times losing fix.
More testing needed though..

nice, try also glitch kernel=)

Hi!
I had tried different modems but none of them worked so the only solution I found was to open up my SGS and then do some hardware fixes....had to bend the connection "wire" of GPS. Now the contact between GPS and antenna is good, so this means I get the satellite lock in few second, even indoors!
Just search Google or Youtube and you will find how to do it.

Cleared all GPS stuff with GPS aids (yes I payed 2€ for it but was getting desperate)
and now it has been working just great for about 4 days.
I also flashed another ROM prior to clearing, and it (gps) worked ok after the flash. I'm not sure which or both did the trick but now it's working..
I'm currently on slim ICS and my modem is JW4.

GPS AIDS is a great app to improve your signal.in settings u can NTP server,its usually set to world or north America.change to your region.this will improve your signal significantly.

[Q] The best gps

Hi all, i wanted to ask which is the best rom for gps navigation because i will travel and i need the best gps rom could anyone help me ?

For what I know the thing that affects GPS is the baseband, ril & kernel. Not really about the rom itself.

I use temasek rom and kernel. Gps works great, very fast fix!

Sygic 11.2.6. been using it since i got my phone. Great

its important to use mobile data for A-GPS for quick fix.
and i use navigon, its very good navigation software.

i would also suggest you Sygic (3d, new maps, high quality), as well as FasterGps (by Dominik Schürmann, creator of AdAway)
In addition, you can also use GpsFix by Android Labs for a faster gps fix

I use sygic too and am so far pleased. If you have a car charger use it or change the settings for better performance (more battery drain but lot faster). It is the default profil if the phone is charging. I don't use A-gps cause the data over mobile network is still expensive here in Greece!

Thanks everyone for the reply! I just installed Sygic and it's wonderful. Thanks.

Wireless sleep policy

Hi,
On any ICS ROM I install, my phone doesn't stick to the wireless sleep policy. It turns off, even though I set it to never and the coverage is fine. I thought it was ROM or kernel related, but it does this on all ICS roms and kernels I've tried. On 2.3.7 it works fine.
I've had this problem for ages and it's driving me mad, but I've tried everything I could think of and nothing worked. It made me think it might be a hardware issue but that doesn't make sense for a sleep policy and it definitely still works on Gingerbread, so I'm completely lost.
Any help would be greatly appreciated!

I'm assuming you mean this app? https://play.google.com/store/apps/details?id=org.wahtod.wififixer
I'll try that, but I'd rather fix it without installing additional services, because that should be possible.. It's really just fixing the symptoms, not the cause.

I've tried and the app works, so thanks for that. The service cause quite a significant battery drain though, because it switches wifi off and on regularly, so a real fix would be nice, if anyone has an idea.
