Here is why their logic is flawed in my opinion. Typing in that key combo would be like typing in some random command at a "root" level command prompt without understanding at all what the command did. It would be correct for someone to post the command in a forum if it said that it sped up your computer and it worked. If it said that it "reset" your computer to an original state would you not back it up to a device external to the computer being "reset"?

Good point, thank you.

hey staplebox, do you have JH7 update?
[Captivate Android Development] docflower:
Sorry for messing up your thread. I only posted about the GSM reset because it worked on my phone. I posted my source so others could read it and possible learn from it.

It really seems like people are getting butt hurt by their phones reseting. I personally dont care if my phone resets. Its a phone, not a bank account. If one had taken the time like it says all over this site to "read before you act/ask" than phones would not have been reset.

My post was to add to the discussion for this thread, but obviously it has deteriorated to name calling and general immaturity. I respect most everyone on this forum but it takes a certain something to deal with the uber geeks who get so saddened by a life, ooops, I mean phone reset.

Lighten up people and stop tripping out over new folks learning the ropes. This thread was really useful and could still be.

Get back on topic please.

PS I am using 2.1.4 voodoo and hsupa, did the reset, and changed to MSbased and Auto server and am still getting comparatively great results than previous methods.

Doesn't matter, I updated to the v 005. Not working well
[Captivate Android Development] topshelf95:
I did Odin one click back to stock, then did a master reset using the keypad, *2767*3855# , then flashed the Mini Kies JH7 Update immediately after, and immediately after that rooted with One Click Root, then installed Rom Manager and then flashed Cognition 2.1.5 over the stock kies JH7, and without installing any of the Jupiter files tried GPS. Didn't work and I was about to start installing the jupiter files but decided to do a master reset one more time after flashing cognition. After this second Master GSM Reset with the keypay, GPS worked quite well. Some of these steps may have been redundant, and possibly even unnecessary, but I was going for overkill as I did not want to leave anything to chance and I think this is for me a pretty clear indicator that the GSM Reset has something to do with it. Whether that means it's clearing the cache or not, I don't know, but there was a definite difference on my phone.

GPS now works as good as it ever has, which means that it will track me on the road pretty well but not perfect, still slightly laggy here and there, however, definitely usable. GPS Test has me locked onto at least 6-10 satellites at any time with usually 9-12 visible at any time. Will continue to test it over the next week or so, if the GPS starts to degrade I will start trying the different Jupiter files and see how that works, but for now, the GPS I would say is 90% and I feel pretty confident that I can get back to this position if need be to get an objective point of view on exactly what effect the different Jupiter files have.

As of right now however, GPS locks pretty quick, within 10 secs at least and tracks me fairly accurately. Still shows me off a little bit here and there while driving, but its not putting me onto side roads and its way better than before. The bottom line is, it will lead me where I need to go if I don't know the way. ;)

I'm running an older Cog version 2.1.0. The baseband is listed as JH7 but I think it is the pre-release version not the latest OTA but I am not sure. I should keep a personal change log because I loose track of the different mods.
[Captivate Android Development] creepyncrawly:
I'm running Cog 2.1.1 and updated from 2.1.0. This version of cognition includes the ota jh7 firmware.
[Captivate Android Development] jaxf250:
Installed fresh Cog 2.1.5 from Odin reset to JF6 (stock). Then put on Jupiter 005 files, did battery pull, did "delete gps data" from Lbstestmode app., and observed the following:

- no fix indoors

- when at a window, only seeing 1 or 2 sats

- when outside, took 68 seconds TTF and saw 10 sats, showed accuracy of 5 meters. Google maps then locked on right away. Was stationary, not moving.

So indoors not working, I get that. Expected. But with Cog 2.1 and Jupiter 001, I _could_ get a quick AGPS lock indoors (I am assuming that is what it was anyway), and when near a window I got 4-5 sats and a lock within 30 seconds.

I post this just for more data points for CL.... I think we are onto getting this nailed down, albeit slowly and with some ROM and config files needing to be changed.... I offer a thanks to all who are testing each of these for the community and reporting back our findings. XDA rocks.

Help or shut up

Alright, I joked a little about logic, others are getting a little rude about this. We all started out not knowing what we were doing at one time or another, that's how we learn, get it, LEARN. They made a mistake which I know we've never done before. :rolleyes: Rather than piss them off to the point that they won't come back, we razzed them a little and then explained how you avoid doing that the next time. It's called "constructive criticism" and is used when

a: you remember how deflated you felt when you did that (with a chuckle hopefully) and

b: to help others bypass that with your knowledge.

Either try to help or shut the **** up! You're not helping if all you do is cut on them and then offer no input. johnyhoffman, I'm not saying you specifically, you just happened to be that post. Come on people, yes it's funny but you were there at one point or another and you know that its hard enough to admit that you screwed up, but even knowing that you came back for some insight and someone helped you through your "noob" mistake. Remember how grateful you were that some one took the time to offer you advice, WELL BE THAT PERSON! or shut the **** up! Really, jack asses not needed here.

Sorry about the language but I will not take it back because these places are for knowledge and passing that knowledge to others to end up with a better end product for yourself and others. They are not for simple minded little pricks that get a rise out of downing others for their amusement.

Lecture frikin done, I'm the **** out!! :mad:
[Captivate Android Development] tazman171:
You didn't mess this thread up, just a little more info next time for people that are just starting out (including me, I'm no expert in this. That's why I'm here ;) lol) Put it in "laymans" terms I guess would be the best way to put it. What you posted has worked for a lot of people in other threads and sites. :cool:
[Captivate Android Development] tazman171:
Sorry CLShortFuse for getting angry on your thread, the info here has helped me and many others, I didn't mean any disrespect to you or the information provided here. Just wanted to preserve that flow.
[Captivate Android Development] askpcguy:
I flashed the JH7 firmware using Clockwork and restored my apps + missing data using Titanium Backup. GPS performance was terrible. LbsTestMode saw 8 satellites but got no lock.

Can anyone tell me the name/location of important GPS files because I want to get a comparison going.

I tried the i9000 ROM and saw GPS performance become dependable. I was a little annoyed by a few items so I restored my Nandroid backup followed by the Titanium backup restore all apps + system data.

Now I have mis-matched versions according to *#1234# but my GPS is still amazing. Locks in 30 seconds in GPS Test.

Also: Please keep posts relevant to GPS. I absolutely hate seeing a reply to this thread then come to find out its some arguement going on.
[Captivate Android Development] tazman171:
Mine were relevant to the thread, I totally agree with that need and there is no argument, merely stating the facts.

When you say that the gps is amazing, are you getting totally accurate positioning using Tracks, Nav, etc? I only ask because your lock time is longer than others but that is not necessarily a bad thing. My old tilt takes a few minutes to get a lock but when it is it stays locked and accurate on 7+ sats the whole time. I would gladly trade quick locks for stable and accurate locks with a bit longer wait for them.
[Captivate Android Development] ewingr:
I am a bit confused. So...which setup are you using that is providing good GPS results?
[Captivate Android Development] TheSopranos16:
Just thought I'd post my experience with v005. I am running JH7 OTA through Clockwork flash and installed v005 yesterday. Unfortunately, I see no improvement in GPS in either lock time or tracking. In fact, I think its worse. But I will continue to follow the thread in hopes that we are down the right path and a future version will provide better results.

In the end, I can't find the words that could possibly express how silly it is that we have to sit here everyday and try to reengineer a basic function of our phone because 2.5 months wasn't enough time for Samsung to fix it. Its inexcusable.
[Captivate Android Development] KMan94:
I'm getting a general sense both in this thread and the Cognition thread that people are giving up on GPS fixes until the fundamental firmware issues are addressed. I've gathered that the hardware seems to be there but how its put together is just wrong. Maybe I'm still just hoping the phone can still be made GPS capable...
[Captivate Android Development] mindfrost82:
I have Cog 2.1.5 with the 1.10 voodoo kernel. I also manually flashed the Vibrant files before I knew Cog 2.1.5 had them included.

Then I copied over the jupiter and gps.conf files from v005 to /system/etc using Root Explorer.

I have Use Wireless Networks Off.

I used the settings above with the Google supl server. I have Skyhook off.

First lock took a little while and accuracy was still off for the first 10 minutes of my drive yesterday, then it locked on and has been good since. I finished 20 more minutes of my drive yesterday and used it for 30 minutes today while it was in my lap.

I was also able to use NDrive today and it actually held the lock and kept me on the road, which is the first time ever with this phone.

I will continue to test to and from work and see if it lasts.
[Captivate Android Development] askpcguy:
This was why I asked about important GPS file locations/names so we can start to compare them.

I versions went something similar to this. JF6 > JH2 > EU i9000 ROM > Restored JH2 Nandroid > Used supl.google.com in JH2 and I started to notice I'll get a lock in lbstestmode in seconds, or in gps test, or even in google maps.

As for navigation, yes it'll still act crazy and decide I jumped to another street while stationary and I'll get the blue circle from time to time.

For the tracks, I have not used any apps to test this.
[Captivate Android Development] egzthunder1:
Thread cleaned up.
[Captivate Android Development] lpsi2000:
Not really, I think GPS is still unreliable. It seems to work at first but after day or so I am back to not being able to get lock fast enough to not being able to keep the lock while driving.
[Captivate Android Development] tazman171:
That's my experience too, "adjustments" seem to work for a day or so and then things seem to slowly get worse. The locks are never steady, the gps always seems to be switching sats and positions constantly, that seems to me to be the real problem. Every other gps device I use stays locked to the same satellites once locked, not constantly locking new ones while dropping the others just because you move the phone 2".

It's been brought up here before that this is possibly the real problem but I don't know myself as I don't have the skills to look at the hardware/software processes and understand what I'm looking at. I really wish that I could, but I can't, yet.
[Captivate Android Development] CLShortFuse:
i9000, Verizon and AT&T use a Jupiter driver.

The i9000 don't work on AT&T. It crashes with libgps.so

I haven't fully test the Verizon but if i9000, which is GSM doesn't work, it'll be less likely Verizon's CDMA one will.

T-Mobile Vibrant uses a different agpsd driver scheme (libclientgps.so and secgps.conf) which runs on the Captivate but since it's not Jupiter, I can't really tweak the settings. There's no real notable difference.

LBSTestMode is a whole other issue. It's referenced in the driver. I'll test more but I'm wrapping up some projects for work that have priority over this. Then I can compare, disassembly and tweak.

I would want to put all types of drivers (verizon, sprint, i9000, captivate, vibrant) on the first post with different versions (JI2, JI4,JI5, JF6, JF7) to better understand the difference.
[Captivate Android Development] tazman171:
That sounds like a good way to go, seeing the differences between the versions would be a lot of help. Beeing able to log whats going on as an end user and posting it here would be good info, but I personnally don't know how to do that but would like to help with providing that info if it can be useful. When you have time (Letting work take priority, what's that about! LOL) could you list what would be needed to get that data? Just want to help get to what is really going on.
[Captivate Android Development] CLShortFuse:
froyoJupiter looks nearly identical to my v005, except for the normal fix resetting everything
[Captivate Android Development] askpcguy:
Important GPS filenames, locatons please.

I want to compare what I have with others to see if there are any differences and more importantly if these differences prove to be helpful.

I'll adb pull the files down and we can get some additional data.
[Captivate Android Development] Dani897:
I stumbled on a way to get better nav performance. Google maps annoyingly tries to gain a new fix when you switch applications and switch back or when the screen turns off or when you stand still too long. I have been caught at a traffic light for too long and it suddenly turns the gps off, maps is running but the gps icon disappears, then I can't get a new fix in a reasonable amount of time. Add it doesn't try to get a new fix on its own.

I have noticed that once it has a fix it has no problem keeping it and that if lbs test is using the gps maps lets lbs control the gps and simply uses the position. So what I do is

start test mode and get a fix.

Go back to home screen via home button not back button.

Start maps.

The gps icon should not be pulsing, and maps should already have a fix.

Edit: ^ this does not prevent the gps turning off after several minutes but does get a faster fix than maps on its own and keep the fix if you exit maps and return within a short time.

Also although I lack the knowledge and experience to test it fully I find that my gps has best accuracy with the gpu clock set to the stock 200 clock speed. it may be coincidental but I sometimes see a fix that claims to be 10 meter accurate but is 70 meters from my actual location. This rarely happens without my usual overclocked setting.i also find that the stock jupiter file gets a fix closer to my actual position. But again may be no more than a coincidence. It is hard to tell when your problems are so random and unpredictable.

[Captivate Android Development] tazman171:
It looks like it still tried to take the direction it thought you were going and then came back to the street you actually turned on but much quicker. How is your traks when you just set it down in one spot for 10 to 15 minutes?

BTW, that does look much better than the usual mess. :D
[Captivate Android Development] CLShortFuse:
That's stock.

I just tested my fix.

v006 eliminates the "sliding" effect but breaks the compass. I rather eliminates the sliding than tell me which way I'm facing.

I only made three turns this route now but when I drive back I'll test it better.
[Captivate Android Development] ThisWasATriumph:
The compass still works when not using the gps right? Like if I use the compass app?
[Captivate Android Development] CLShortFuse:
Compass works. This thing is ridiculously sensitive and I'm not sure changing to supl.google.com does much of anything. In fact, I think it's worse. I'm going to start using spirent.

Anyone has solutions to Froyo? I don't even ask for a fully working standalone GPS anymore. Just want my aGPS to work like when I had OTA. Now I can't even get more than 2 Sats.
[Captivate Android Development] tazman171:
I personally have always had better luck with spirent. Don't know why but it is the one that came with the phone.
[Captivate Android Development] askpcguy:
Again I'm going to ask why anyone hasn’t responded to the request I keep making.

Nobody thinks it'll be a good idea to examine GPS configuration files in hopes there's something that can be changed to improve GPS performance?

And I know that's the idea with this thread but I'm talking about a comparison.

[Captivate Android Development] cesierra:
I am looking for a way to prevent the gps from sleeping when the phone sleeps. It is very annoying having to wait for the gps to lock again everytime I need it.

So far the workaround is to enter lbs test menu, start the test and leave it runing in the background.

Is there any quicker way than this?

Froyo JI6 Jupiter fix

I just tried Version 006 that was just released this morning on my phone with Froyo JI6 and when I used both the gps.conf and secgps.conf files, it caused my phone to not boot fully and just hangs. Luckily I made backups before I did the fix in adb. The jupiter.xml does work fine though.

Did anyone else have these problems?
[Captivate Android Development] mindfrost82:
I would also like to know if there's a way to change this behavior.

The GPS Status app from the Market has a setting to keep the screen on as long as the app is running, so that's another possibility if you always want your screen on.
[Captivate Android Development] newter55:
I have been following you guys and doing a lot of test drives and the sliding you mention seems to me to be at the heart of the problem....when I watch my lat/long on gps status app it only lags for second or so but in maps and tracks it really drags like the google app is trying to force me to be somewhere I am not until it finally gets back on track or gives up and tries to get a new lock.

Just my uneducated two cents

[Captivate Android Development] ThisWasATriumph:
On unchanged froyo, if I change the mode to MS-based with the supl stuff changed I cant get a lock even though I see 9 sats. Keeping it on standalone gets me a quick lock however...
[Captivate Android Development] gordec:
http://www.youtube.com/watch?v=eP7pQQ9m-6Y this guys shows stock Cappy with no aGPS locking like a champ. So jealous.
[Captivate Android Development] Justinph5:
This is the way mine has been, it used to be slower on the locks from stock, but good on navigating. I've tried v001 here and it made locking faster. I'm now on 2.2 stock and locking is even faster, I'll lock anywhere, even indoors, within 10 seconds. Navigation has always been the same and worked on it. The only time the GPS would seem weird is for a day after each rom flash or change I did, after a day it would be back to good.

So does anyone want or need any files off my phone? All you have to do is tell me which files and where I can find them. :) I think mine would be a good one for "working" GPS files to compare.

Can I have your phone instead?

thanks CL I did a 10 mile test doing some errrands and stopping for breakfast, you can see its worked really well, tracked us through a parking lot properly and even seems to be on the correct side of the street for the most part, It was a cloudy day with a little rain and it didnt even hickup at all.

h t t p : / / w w w . appbrain.com/app/tracker-booster/com.kaukovuo.android.trackerbooster <----remove spaces.

This works well for me. Allows me to neurotically switch back in forth between between maps and gpstest constantly while driving:)

If im leaving the house, ill fire this up and it helps me get a lock by the time i'm ready to use GPS. Probably not a good idea to leave on all the time though for battery's sake.

hope it helps

Thanks, I bit the bullet and flashed to 2.2 COG, copied over V6, works like a charm. I've had this phone for over 3 months and this is the first time GPS has worked well. Can't wait to test it out in my car tomorrow.
[Captivate Android Development] Dani897:
Gps is still just ok on froyo, I'll play with it more then try your new jupiter file.

The pre ota update gps performed best for me as long as the skies were clear and the phone was on the dash of my car. I used my phone to nav on a 6 hour trip and all went well for 4 hours till I hit rain. Since the ota, the gps was able to get a fix without a clear view of the sky but now I see the run on arrow you all complained about, in the beginning I didn't have bad gps I had either good gps or no gps. Since ota out has been consistently less that perfect.

I tried your jupiter v1 and then jupiter v5 but the gps would turn off at random if I was driving.

Overall it is at least reliable now on cog 2.2 It can recover before it causes problems but the arrow does wander quite a bit. But Its at a point I can work with.

Oh well, it is what it is. Maybe I'll sell my soul to verizon for a droid 2. Nah I still love my phone.

Short fuse I hope you get this figured out. You seem smart enough, but I'm not sure how much better the phone can do.
