[Q] Poor Data Service Need Suggestions

OK so I need some help . . . . . after flashing a new ROM/kernel, I noticed that my network service was insanely poor. I thought it had to do with the new ROM but now after I have tried every which way of flashing and reflashing, I still have the issue. I used Speedtest to see what kind of DL speeds I was getting and I am usually in double digit kbps, 114kbps is my top. My wifes Acclaim regularly gets 600+ to the same server. Does anyone have any suggestions of what I may have screwed up or how I can go about fixing it? Everything works fine in WiFi btw.
Thanks in advance.
Fixed: Somehow I managed to get knocked off my 3G service. Called USCC tech support and they were able to turn it back on for me.

Try updating your prl. Dial *228 when at home and not roaming. Follow the prompts and wait for it to update. Should help and really can't hurt.

Yeah I tried that. No dice. Thanks for your suggestion though.
Maybe it's a hardware issue?

Is it even possible to "break" something like this by flashing new roms or kernels? Everywhere I used to have 3G service I now just have 1x.

I called 911 and it didn't work. The 911 operator didn't have any ideas either.

Well it's starting to look like I should start think about buying a new phone. I have tried everything within my ability and nothing. In a last ditch effort, where could I find a flashable radio that I could use just to make sure it is installed correctly?

Try going back to 2.1 and see how the data is. I somehow got a new prl when I flashed aosp and my girlfriends phone is on an earlier version. We both did the *228 and hers stays at 15108 mine stays at 15110. There is supposed to be a way to manually update our roll back prl. Idk wish I did

I did flash back to 2.1 and the data issues remain. The PRL on my phone and my wife's Acclaim are both 15110, but she gets 3G service and I don't. It also takes over a minute for my 1x service to load after turning off wifi. Also, If I force EVDO, I will get a "3G" banner at the top of the screen, but data does not work and the banner eventually goes away.
Additionally, is it normal to get a Verizon voice when you *228 while roaming? Because that is what I got when I was roaming yesterday. I have to believe that flashing Fascinate software has something to with it.

You could check the efs clear box in odin. I know it has something to do with service. I did that once in my vibrant by mistake. Are you dialing 911 in your home area? It needs to be in a uscc home area same with *228. The efs clear might break your phone worse so.......

Yes, which is why I said do it while NOT roaming. If you completed the *228 while roaming on Verizon you basically connected your phone to their network not USCC's.

I did the *228 at home while not roaming. When I got the Verizon thing while roaming I just hung up I never went through any kind of programming. This was well after things went awry anyways.
I believe this all started a few days ago when I tried flashing the ComaVolt kernel. I got a boot loop and had to do a battery pull. I then flashed dfgas's superclean port and I thought everything was working fine until I got out of wifi the next day and noticed my network service was aweful.

Go back to di14 and do the *228 and dial 911

Do you have a belief plan? If so flash it to stock with odin and take the phone in and tell them to give you a new one. Even if you don't have a belief plan I would flash it ti stock and take it in telling them it's defective. worth a shot. Sorry that nothing is working for you bud.

I do have a belief plan but I bought the phone on Ebay a few months back. I was just out for a bit and the banner at the top would go into "3G" but while it was like that I had no network connection. Somehow I pooched my 3G radio I guess. Maybe I'll call tech support and see if they can help. Everyone I have ever talked to over there has been really good so maybe it's worth a try.

Need help with GPS locks

I need help because my GPS wont lock... I've tried the G2X bloater and installed my region but it still wont lock even after 5 minutes.
EDIT: I'm on Faux's AOSP Rom with his kernel as well.

Do you have the newest baseband? That helped me lock much better.

What's the easiest way to install that? Do you have to flash official gb?
Sent from my LG G2x

I'm not familiar with your ROMs, however, I find it helps to have an unobscured view of the horizon in most directions and to not be moving in a car. If that fails, I then use an app called GPS Test by Chartcross Ltd. Go into settings and there are two buttons on the top labeled: Clear AGPS and Update AGPS. Try each of the two buttons.
I just looked up AGPS and here's what Wikipedia has to say, "Assisted GPS, generally abbreviated as A-GPS or aGPS, is a system which can, under certain conditions, improve the startup performance, or time-to-first-fix (TTFF) of a GPS satellite-based positioning system." Hope this helps.

the only way to install the new baseband is by using lgupdate tool, or kdz firmware updater along with the kdz file. try the lgupdate tool first. there are numerous threads explaining the process,which for some is a one click success story. for others, a walk through programming hell. the lgupdate tool is plagued.

Alright thanks everyone. I AM on the newest baseband, but am trying cm7 now

Let us know if this fixes your GPS. My GPS sucks taint too, and will upgrade the baseband if it fixes it, but don't want to risk the possible PITA using the LG tool if it doesn't fix it. Everything else other than battery life is amazing on my phone.

Download from app market gps test, then after you run the gps test go to setings and hit clear agps and also update agps then it should lock under 15 seconds

Gps not locking

my gps does not lock for some reason no matter what rom i try. can you guys help?

Did you clear your data/cache..? (Maps) How's your signal.what GPS are you using
Sent from my SCH-I535 using xda premium

I am having a similar issue, but mine takes a good 10 minutes to lock on a signal. This is with a clear sky view and using google maps.
It seems to be getting worse lately. I am on Root66 with the bootloader still locked by the way.

I'm having the same issue as well. It was working like a champ before I flashed CM10.

I truly think it's because we all know Samsung makes great phones, but they lack in the radio department.mine takes a while sometimes even with a clear view of the sky.I think a good update to fix these radio issues would help out allot, unless our xda community can step in before especially now with an unlocked Bootloader

I'm also seeing trouble with my gps not locking. It's only been in the last couple days, and I've changed nothing since the time that it had been perfect.
Makes me think there's something satellite or google related?

Download "GPS Test" app from the market. Open the app. Go into settings and clear AGPS, then update AGPS. That worked for me. Try that before you Odin back to stock.
Sent from my SCH-I535 using xda app-developers app

As previously stated, I am NOT using CM10... I tried to download "GPS Test" 5 times and got an error 491 all 5 times (with wifi on or off, did not matter).
EDIT: I restarted my phone and then it downloaded just fine... that is another annoying issue!

GPS
My phone with the stock Rom would generally asquire a GPS lock quickly, but tended to lose it more often than other phones. However, on CM 10 I have had trouble locking as well. For me if I put my phone on the dashboard I usually get a lock in about thirty seconds. I know that doesn't fix it for you, but it is the workaround I've been using so far.

Put a modified gps.conf on.
Use fasterfix and pick a local NTP server.
Turn on google A-GPS (Location services).
It still doesn't lock through objects as well, but it's quick outdoors.

I can confirm that this worked for me as well. Also, when I have locking issues in Maps or Waze, I just launch GPS Test and wait until the "In Use" # of satelittes is 2 or more. When I subsequently go back to Maps or Waze, I get an immediate lock.

I wrote up a lot about this for my previous device, the htc mytouch 4g slide. See this thread for some gps.conf info:
http://forum.xda-developers.com/showthread.php?p=16822068
GPS is a real big deal for me, I use the smartphone to get to/from work daily, and my job takes me all over the country so I am never familiar with where I am.
The SGSIII locks quick and accurately outdoors with only gps turned on for location services.
Totally stock, and haven't put it through it's paces yet, but been wandering around in west virginia all day and it's been great.
Clear view of the sky is necessary for good gps function, so trying to use indoors or even under lots of trees is a stretch.
Outside, maybe in a parking lot or field, would be the best place to try to use gps.

I found that flashing back to the actual verizon f2 build and then rooting without flashing a deodexed stock rom helped to retain gps with other TW roms like beans or synergy.
Right now I still think that CM10 is risky and you might need to flash stock back on your phone if things stop working like they used to.

I came from the samsung fascinate which had horrible GPS service for the first 6 months. OTA's were sent out to fix it but it never really worked well. I tried all sorts of programs and configs and deleting files, etc, which might have helped some but never great until one of the devs fixed the issue in the kernel. After that I could get instant lock indoors/outdoors/cloudy skies/etc.... super annoying to go back to a crappy GPS.

I tried this app, it didn't work as I had hoped. At first the app was successful at getting a quicker GPS lock than Maps, but after clearing & updating AGPS, it takes even LONGER for it to lock!
Has anyone else found another method to fix this?
PS: my phone is stock.

others have also suggested using Gps Status & Toolbox, similar to Gps Test.

No GPS with SyNthetic_aospX 1.0.0-BR7

Please forgive me if this has been asked and solved before. I'm having a problem with GPS locking on this rom only. I tried updating the GPS config file but had no luck locking on. I'm in an area where with other roms I can typically lock onto about 7 or 8 satellites. Any help is greatly appreciated!

I did try using GPS Status to "reset" the GPS. It did VERY briefly find two satellites and then they disappeared. I've tried re-downloading the rom, wiping, etc. with no luck. I'm just bummed out cause I really like this rom but no GPS is a no-go for me.

Gps works. Try more apps. Get a fresh download. There are always more things to try.

You said it works..are you using an app from the app store, or is it working from the Rom itself? It's my favorite Rom but I rarely use GPS. I just wanna know in case I decide to use it.

I did download GPS Status from the Play Store and I use navigation daily so it's pretty important to me. I don't know why sometimes it seems to see less or more in the same location but I used the turn by turn directions last night just fine. I'll let everyone know if I see any changes but right now it seems good.
I also flashed the Wi-Fi calling and it's working out, thank you. Looking forward to your future projects!

Anbody on WIND have a solidly working GPS?

Anbody on WIND or any mobile carrier for that matter have a solidly working GPS?
If so... can you please tell me what steps you took to get it working that way. What rom, kernel and additional files if any did you install?
I love the CM 7.1 nightlies as my daily driver but even after changing the gps.config to supl.google.com and port 7276...it takes forever to get GPS lock and sometime doesn't even lock at all.

wind mobile, using hackfest PA, stock PA kernel
the trick is, use fasterfix, or edit the init.d yourself, and set it to canada
your gps will get a lock eventually.
however dont expect it to get a lock fast, g2x has **** load of bugs and **** and is quite well known for having a slow ass GPS.
It usually takes about 1-4 minutes to get a lock depending on the sky condition.

what do you mean BT dont work? I bt tether to my tablet sometimes and it works perfectly.
are you saying BT audio? I dont have a handfree device i can test with bt so i cant say for sure.

30 second locks every time if I am outside. Mobile data needed and I am on stock Rom. Modified hidden menu GPS setting but GPS conf is still the stock one (believe it or not, wrong servers in it and all, but still works ).
Maybe it's just luck, but then, I have two g2x and both work identically good locking to GPS signal.
Bluetooth audio is a deal breaker for me, so nothing but stock for now
