[Q] GPS Problems, wrong modem flashed? - Galaxy S II Q&A, Help & Troubleshooting

Hello
A few months ago I got my galaxySII and installed CyanogenMod7.1 by following a tutorial. It was my first time and I did a mistake, I didn't write down my original modem/kernel version.
Now I notice that often my phone needs a VERY long time to find a GPS signal (e.g. when starting NAVIGON navigation app). (Of course I am outside and not in a building). Often it helps to turn off/turn on GPS or reboot the phone. Now I read here on xda that a wrong modem version can affect GPS performance. Everything else works fine.
My question is, can I find out, what version I should use, even if I already flashed a different one?
Here is my phone info:

Thanks for any help!
edit: I live and got my phone in germany if it helps

Try FasterFix from the Market. If that doesn't help, looks like the modem you're currently using is KI1, try some of the later modems from this thread until you find one that works better than the one you're currently using.

[Q] European ROM GPS problems

The problem is when you get European ROM on Vibrant, GPS dies.
Even if you put CSC and modem from original firmware and PDA part from i9000 it doesn't help make GPS work.
May be someone has any suggestions?
I don't know if I have the same issue as you, but ever since I got to Amsterdam my GPS "works" in that it shows in the status bar, but the location is never accurate by any measure. In fact, I think my location continues to be retrieved by the other means available (trianulation or whatever). I ended up turning GPS off completely since I'm only here for a limited time. It would be very nice to have GPS working though.
No, actually if you have stock firmware installed, GPS locates successfully. With i9000 firmware it never finds anything

GPS isn't working with any ROM

First, to all that have created and contributed to this site, Thank you.
Now I know I'm new here and I'm probably going to get murdered for posting this but I'm completely out of ideas. I've tried searching everywhere and I can't find any answers. I tried flashing the Axura 2.1 and 2.2 roms and my GPS stopped working completley. I've tried using several different modems with the roms. I tried flashing the macnut roms and had the same result.
I've tried searching but there are so many gps problem thread that I can't find the answer(unless I'm skipping over it). So now I'm hoping that somebody will be able to help me out.
Sorry for my ignorance but I really am desperate cause I really wanna get this $500 phone working like one
this needs to be in Q&A, but; ODIN to JFD/JI6, then run the GPSRestore app from the market. If your phone's GPS still doesnt work, then it's the GPS hardware.
I've run GPS on all TW roms, and each one locks quick and accurate.
JL5 and JL5 GPS are spot on.

I don't think you're going to get murdered for posting a question. It just needs to be in the right forum. Next time please post questions in the Q&A forum to keep the Dev forum clutter free.
As far as your problem goes, when you say not working is your gps seeing satellites and just not locking or not seeing any at all.
Is your roof made of solid tinfoil???
Just kidding, but seriously, Odin back to JFD or some other 2.1 firmware and download GPS restore or something like that from the market and go stand OUTSIDE and test it.
If this fails, then you have faulty hardware. Send it to Samsung.

exactly. or your house or where ever you are is getting bad GPS signal. my gps worked flawlessly for a while now. it's just with newer modems, they lock faster.
I had similar issues to what you describe. My GPS would not work with any ROM combination. Sometimes I could see satellites but I would never get a lock. Tried anything with no luck. Finally- I did three things, and I can't tell you for certain which fixed it- but at the end it was fine.
First thing was I followed the hardware fix guide at http://forum.xda-developers.com/showthread.php?t=878970 and then I installed a JL4 ROM (I hear JL5 works great too), left settings as stock and made sure Server FQDN Type was set to Auto config instead of www.spirent-lcs.com. Then I went outside and waited like 10 minutes in LbsTestMode "Get Position Test". Now my GPS works!
I haven't had a real problem with the GPS ever since JI2, and the GPS performance in the Froyo-based ROMs is even better. If it's not working for you at all, then you need to exchange your phone for a new one. You should be able to arrange that with T-Mobile at not extra cost to you.
If you bought your phone through T-Mobile you need to contact them. Jump through their hoops and get a replacement ordered.
Sorry for not putting this in the right forums. If a mod has to move it....
This is exactly whats happening. Whether I'm outside or not, the little gps icon blinks but it says my location is temporarily unavailable. I don't think its hardware cause this is a brand new phone that was working yesterday before I installed the ROM. Thanks for the suggestions. Some more are welcomed
no rom or modem fixed my gps completely till i was on eugene's ginger clone r2 and flashed the JL5 Modem WITHOUT doing the Samsung GPS restore from the market. In fifteen seconds i was locked with less than 10m.

This is a brand new phone. Its my 3rd one in lest than a week. This GPS was working to some extent right before I installed the Axura rom. I just did a the GPS restore and now it still won't lock onto my position but it will do the navigation(poorly just like before) to a spoken destination with voice guidance. If I ask it for a map of something it will bring those destinations up also. I'm at a complete loss but I do like this ROM better than Eclair.
samsung restore isn't in the market anymore.
Can someone upload the .apk please ?
Thanks

Problems since BLG8?

So last night I updated my s3 to the latest UK firmware, XXBLG8, And I can't tell if my problems stem from the latest update!
After the update many apps wouldn't open and I'd have to do a battery pull to sort out each individual app that refused to load, everything's fine now, however, my data connectivity seems to have worsened considerably, even with full signal strength and HSPDA nothing will load, the browser shows errors that I'm not connected to the internet and apps such as the Play Store and Speedtest won't connect.
Anyone else experiencing this problem? Would I be able to flash back to an earlier firmware using ODIN? (I'm new to the s3 scene, just jumped ship from a Desire HD and haven't yet fully got my bearings.)
Thanks guys!

only problem i have noticed is that speedtest does no longer work but everything else perfect. Infact my hsdpa connection is much better on this rom. you can easily downgrade your rom back if you wish just follow this excellent guide to flash via odin.

Hmm, I suppose it could be the area I'm in, but it's usually fine where I am. I'll give it another couple of days and test it in other areas to see if the problem persists.
I've upgraded via ODIN before, just wasn't sure if there were restrictions on downgrading etc, I'll give the thread you linked to a good read now, thanks!
Try changing Modem BULF1 for starters .
I find the last two updates modems are very poor .

I am also on the 8 firmware and so far it's good.
looks like speedtest.net have changed there site slightly if you goto site with mobile agent set on browser it redirects to the play store to the speedtest app, change browser to desktop as long as you have flash installed all is fine. I believe this has been done site to the up and coming removal of mobile flash

Thanks, I'll give it a go!
So I decided to bust out my Desire HD, I remembered I still have a month left on my old contract before it gets terminated, checked the data connectivity on there and I seem to be having the same issues. Looks like it's a problem with 3 in general rather than it being my s3. Which is good news for my s3!
Must have been pure coincidence that I started having these issues right after upgrading, however, I tried a few new modems and have been getting better signal (no change with the data issues) so at least I've taken something away from the experience
Isn't there an issue with 3 UK branded ROMs experiencing network issues when you flash the unbranded ROM? I think you may need to flash a separate modem, Google it, I may be wrong.
I'm on 3uk running blg8 not had any problems making, receiving calls and texts and my network is fine on both wireless and 3g

It seems to be working pretty well this morning on both my s3 and DHD, and Frostfree I'll have to check that out, I've already flashed a few new modems and I'm getting better performance so that might very well be the case!
I'm in Folkestone (south east coast)
I am on BLG6 with Cyanogen Mod 10 latest rom and so far I have great speeds (4-5Mb) on speed test app.
Will try flashing BLG8 when i can find a download link. I just want the modem to flash not a whole rom cos i am loving JB on the SGS3.

[Q] SGS2 Modems in Australia

I'm having nothing but headaches searching for this. Plus, I'm relying on the internet on my phone to fix the internet on my phone right now, so I've got very little on my bandwidth cap left this month. I'm hoping one of you can help me so I can stop draining my cap with searches that just make me tear my hair out (especially when the internet drops!)
I've got a common problem, the internet connection (and sometimes the entire connection) drops out constantly. In my searches, it appears clear that I need to flash a new modem.
I know I need to do it with Odin, that's fine. My problem is finding a download link THAT WORKS for a modem to flash. I'm happy to try a few until one works for me, but if anyone knows of one that will give me a solid connection to Optus, that would be a bonus.
I'm running Cyanogen 9.1.0 (4.0.4).
Baseband is I9100TDVKF2 (and I assume the "T" there indicates that this was originally a Telstra phone, which it was).
I'm rooted.
I'm unlocked.
Thank you!
Read/search through this thread. Plenty of posts from people at various times mentioning modems which work well with specific networks. That will give you a good starting point.
Obviously look for posts from people who tested X modem with Optus & found it worked well, search for said modem, flash it, test in different locations/preferably over a couple of days to get a feel for how it works for you. If it works well, problem solved. If not, try another. Repeat until you find one that does work for you. Sometimes people using the same modem on the same network can have varying experiences due to carrier side issues (carriers using different equipment on different base stations, congestion issues, etc, etc), so tho most people find certain modems work well with certain networks most of the time, this isn't a given.
To be perfectly honest with you, that sounds like carrier-side/network issues to me.
Ah, thank you!
This is the link that I so desperately needed.
I've flashed DULP4. Here's hoping it works!
Thanks again!
You're welcome. If you're still having probs after testing, post to the AU thread I linked to in my PP & someone using Optus should be able to help (eventually).
All good, it seems to have done the trick. It's much more stable now. Cheers!

[Q] Modem Help

I have a Samsung Galaxy SII, the i777. I have rooted it and loaded ShoStock3. I love the ROM except I'm having trouble downloading apps from Google Play. The research I have done suggests that I need a better modem. I have downloaded and flashed six different modems. Each one just as slow as the last. I'm in Salt Lake City, Utah. I know that the location can have something to do with the modem as well. Does anyone have a suggestion on which modem would work the best? Also, if you happen to know that there is a separate problem and that it's not the modem, will you please let me know? Everything else seems to load fine, it's just trying to load apps from the market that I'm really noticing it is really slow. Thank you everyone in advance.

Modems are good in different places. What's good for me might be awful for you. Have you done a speed test?
Sent from my SGH-I777 using xda app-developers app
You've already flashed 6 different modems, you should know by now which one is the best for you out of those 6.
If you don't like them all, try some more and pick out the best.
Have you tried KH7 or LL6?
Side note: why can't you use Wifi for Google Play?
You are I assume flashing modems for this device right? I only ask because obviously the i9100 modems wouldn't work for us. (And I'm pretty sure calls don't work with them) also, if you are flashing all these modems and they ARE for our device, and NONE are working properly, I would look at a fresh flash of the rom of your choice wiping everything again or going back to stock to eliminate hardware error possibility.
I did verify that they were all for my model and network. None of the six were any better than any other. I also noticed none of them worked on the 4G network. I tried to download an app to do a speed test but after 30ish minutes waiting for it to download on each modem so I could test it, I gave up.
Shoman94 changed to UCLL6 modem on his latest build. Are you using this one now?
Or you can select all the modems from here:
http://forum.xda-developers.com/showthread.php?t=1336958
They seem to be working OK, at least for me. I have tried at least half of them although I am still running ICS (CM9.1), not JB like you.

In the Settings of ur phone, since u r runnin SHOstock 3, do u have the Mobile data box checked under Data usage ? And do u have the "Set mobile data limit" box checked under Data usage (this could hinder u) ?? And under More settings/Mobile networks is the Network mode set to something Other than the "GSM/WCDMA (Auto mode)" (this could also be the problem)??

So, I un-rooted my phone but from what I understand, even doing that won't re-set my modem. It's still working slowly. My biggest fault here was not doing speed tests from the beginning and not noting down what my phone came with. If I could find what modem my phone came with, I would root and load it back on.
I really appreciate everyone's help and suggestions.
Is there anyone in Utah on the 4G version of the SII that could tell me what their modem is?

Check your APN settings, that can cause plenty of issus for data.
