Default A fix for Motorola Triumph's Slow GPS (by updating GPS library)

I register an account to let you know that long GPS lock time is a software issue and not a hardware issue. It can be fixed by updating the Triumph's GPS library.

Follow These Steps:
1. Root your phone (use gingerbreak.apk) and install clockwork recovery (http://androidforums.com/triumph-all-things-root/385385-motorola-triumph-root-guide-upd-7-30-2011-a.html).

2. BACKUP (I am not responsible if something happens to your phone).

3. Go to this XDA thread ([6.Aug.2011][Dev] GPS Libraries v2.0 with AGPS support for HD2 Gingerbread - xda-developers).

4. Download GPS_Libraries_v2.0_RPC_for_HD2_Gingerbread_update. zip (Thanks tytung for developing this fix)

5. Put the zip file on your sd card and flash it through ClockModRecovery. Restart after flashing.

6. Turn on GPS fix application. You should see improvement in accuracy and lock time. (For me, I can get a lock in less than 10 seconds)

Please let me know in the thread if it works for you.

EDIT: It seems like turning on wifi increase GPS lock time but not by much. If GPS lock is still slow for you, try to disable WIFI.

Thanks

I am going to give this fix another try step by step and see if I missed something because I tried this the other day and nothing, my GPS still will not lock and Gps Fix shows I have about 5 or more satellites connected.

Hopefully 2nd time is a charm and there are some really good YouTube videos on how to install Clockwork mod on your Triumph on YouTube for anyone who is hesitant.

EDIT: I did the 2nd install and on the first attempt with Gpslock, it had 6 or more sats connected and was hanging but I got a location after about a minute and stayed locked on so I will update again later today as I am heading to Chicago and that will be the real test.

Hope at least!

Thanks for posting this fix. I tried it this morning and my GPS seemed to lock in faster. Usually it would take a couple of minutes to lock on but today it took less then a minute! I will do more testing today and keep you posted! Again thanks for posting this!

I am suspicious of people reporting better lock/fix times using some modification.

When I have performed a fix and that is cached, yes, subsequent fix attempts are fast and that isn't because of rooting or updating of a library.

Crazy-awesome results! Went from a GPS lock in 3 minutes to about 5 seconds! This is after flashing the v2.1 ZIP.

You guys do realize that flashing this zip on our phone does nothing right. The updater-script inside the zip tries to mount our system partition as a mtd partition which does not mount the system partition at all and then it tries to copy the files to an unmounted system which means basically the files never make it on the phone!

I will try to get a zip that will actually copy the files over posted soon after I test it to make sure it won't break nothing!

I know for sure that my results (posted above) are not placebo. My GPS literally locked in under 10 seconds. That has NEVER happened. I was even in my basement. Are you sure that flashing this has absolutely no effect?

Now perhaps mounting the system partition first then flashing it would work.

I dud it and got the files over on my phone. Mine was already locking fast before and I can't tell much of a difference after but to some it may help more. But yeah just mount system first. Then check by seeing if it added some GPS.bravo.so and GPS.Leo.so in the /system/lib/hw/ folder.

i like using these mount commands for our phone... they are alot simpler than messing with MTD and EMMC crap lol

Code:
run_program("/sbin/busybox", "mount", "/system");

run_program("/sbin/busybox", "umount", "/system");

Sounds promising. I think I tried this method before and it didn't really work. So, let me ask a couple questions.

After doing this mod, does it still work after cold start (turning phone off and changing locations then turning phone back on)? On the XDA thread there are different versions of the file to download, should I always keep the most recent RPC version (currently 2.1)?

I will try this again today. I'm going out of town, so that'l be a good test.

Default GPS doesn't even work

I have used this youtube tutorial below on how to install and use CWMod. Installed the RPC version 2.1 suggested in this forum with CWMod and no dice. I also mounted the system and cache. Phone GPS still can't lock on to my position, any other suggestions?

EDIT: This forum will not allow me to use links in my first post so please go to youtube and put 1H0KMnVy26Y in the search.

Is there a way to just access your phone and overwrite the existing GPS files with the ones provided in the 2.1 zip file by copying and pasting? Just seem like it would be 10 times easier to do it that way...

Yup, do this 1st and it works like a charm. I first tried it with out mounting the other day and didn't see any differance. I read your comment and found in my version of CWR (blue letter version) that there was an option to mount to the system (mounts and storage>Mount/system). Well I mounted to system then installed the zip and rebooted the phone twice to make sure it was a cold start. It locked within 10 seconds from my yard.

Now let me tell you it was hit or miss before. My yard usually took about 5 minutes to cold lock. Most other places a couple minutes. After doing this mod, in my yard took 10 seconds to lock and on a cloudy rainy night. Thats awesome.

So as b_random said you have to mount to the system 1st to make the mod stick.

I can confirm this did nothing for me.

Mounted /system, flashed zip. Ran GPS test, 15s later it saw its second sat... so yeah, no help for me. Running CM7.

I'm inside my room, I have 3 other phones and they all lock pretty fast (10-30s) so yes - it's the MT sucking.

Question I don't understand...

I mounted /system and installed the zip but I do not find the files GPS.bravo.so and GPS.Leo.so. When I try to lock on my GPS signal it won't lock at all.

Worked like a charm. On GPS Test, I instantly started picking up signals that were 30+ and locked onto accuracy within 3 feet.

Edit: And there's an overcast with thick clouds.

Haven't tried it yet. I used CM9 a while back as a daily for about a week and realized I use the camera more than I thought so I went back to MIUI and then CM7.

I noticed turning GPS on kills my phone signal now, but my GPS also locks in literally a second.

EDIT: I'm on MIUI Reportaled (Gingerbread) and my incoming texts don't seem to work. I tested it with a friend. I thought people didn't wanna text me anymore

How do I revert???

EDIT AGAIN: I flashed the 2.0 istead of 2.1 and it fixed the probs. dunno if GPS is still locking in a second like it did before.

EDIT x3: 2.0 doesn't do anything. So.. Have lightning fast GPS lock with no incoming texts. or have incoming texts with indefinite GPS locking ETA.

I tried on mine, seemed to make big difference. more sats picked up, very quick to lock relative to previous gps locks. i usually have it off, and it was a pain when i needed to use it.

Tickerguy has gone into great depth that this fix does absolutely nothing.

The gps fix for the triumph
I pick up cold locks way faster. What I wasn't doing before was mounting my system before flashing so the mod wouldn't stick. I instantly pick up 8 or 9 satellites as soon as I toggle gps on in GPS Test, where as before the mod, it would hang on 1 satellite for quite a while before picking up anymore.

Perhaps you didn't read what he said.

The reason there appears to be is that once you go outside and get a good lock, the ephermis and almanac is in the chip. Until it expires you'll get fast locks (few seconds.)

If AGPS was working your FIRST lock would be instantaneous even if indoors. It's not.

The problem appears to be in the silicon itself and as such unless there's a workaround for the functionality it is never going to actually be fixed. If you want to know how fast a working AGPS implementation should lock play with the Optimus. It's essentially instantaneous all the time as long as it has some view of the sky.

This is one of the (many) dead ends I've run into trying to get the GPS working on CM7.

Once you have a lock the GPS has a good almanac and ephermis for several hours, and partial validity for several weeks. So as long as you don't kill it once it has it, lock performance should be pretty darn good.

The test for these alleged "fixes" is that on an absolutely cold start where it hasn't been used for a couple of weeks (or moved several hundred miles) can you get an instant lock - especially indoors - or can you find a XTRA and NTP download and stuff in the logcat? I can't find evidence of either.

I think you're chasing shadows.

I read it closely. Can't help it if it's evident that I get a lock in seconds rather than minutes. Call it a fix or not, it still works.

I personally tend to trust the guy who dug threw all that code and got things working over anecdotal evidence (even if it were my own). I don't mean to say that you are wrong, but I have yet to see someone prove (with something to back it up besides "It works better for me") that any of those GPS fixes do anything.

People were saying that flashing that worked wonders, then it was found that it didn't even mount /system to write the files. Granted you said that you manually mounted it, but that still doesn't mean the "fix" works. It could be the same as how the others claimed it worked great when it wasn't doing a thing. So please pardon the people that find anecdotal evidence suspicious at this point.

Ill be honest the patch has probably a little bit to do with the locking GPS time. I tried to get it it to lock for a whole night and when I woke up it was still looking for GPS. I tried the same thing but with the updated GPS zip and it locked in less than 10 min. It also depends on how strong or weak you're getting the signal.

Default Not to rock the boat

But the 2.0 zip helped my GPS ALOT.I use my GPS daily for work and before this it would take 5 minutes or more for a lock now it gives me an appox. area in 5 seconds and exact area in 30 seconds EVERY time.Now I'm not saying what others have said about this are true or false I can just speak for myself.It could be that the GPS is much like with the OC of the phone....that each phone is different.It would explain why it works on some but not on others.

Default FasterGPS

It did work a little bit faster, but what helps the process along with this fix is an app called FasterGPS by Dominik Schurmann from Google Play. This nice app acts like a filter keeping it from pinging satellites over places you really don't need. You choose the continent & region you want, (North America, USA for us
domestic folk) and set the other settings as follows:

Debug value- 0
Intermediate POS value-1
Accuracy Thres value- 3000 (adjustable)
Report Pos Use value-1
Enable wiper value-1
XTRA Server 1,2,3 should be pre-set but you should open each one and press the OK button on each item to configure everything to make it work.
SUPL TLS HOST value- FQDN
SUPL SECURE PORT value- 7276
SUPL NO SECURE PORT value- 7276
SUPL TLS CERT value- pre set
SUPL PORT value- 7276
SUPL HOST value supl.google.com
CURRENT CARRIER value- common
DEFAULT AGPS ENABLE value TRUE
DEFAULT SSL ENABLE value FALSE
(all other value listings should be opened and hit the OK button to configure)
Then reboot your phone and it will only take 2 second to get a lock!!! NICE
