3G download problem. HELP!!!!!

I have suddenly been having problems with my 3g. I look at the symbol in the status bar and it will upload but it will not download. It's almost like the code is stuck in a loop. It will randomly start to work again for awhile and then act up later. I have wiped dalvik, cache, and I even reflashed my ROM (FREE GS3). I updated profile and PRL. That was even a problem because I would get an error since it wouldn't download. Before I flash back to stock and call sprint, does anybody have any ideas? One other note. I have driven through LTE areas and both downloads and uploads work with no problem.

Have you tried going back to complete stock unroofed.

Not yet. I'm trying to see what else I can do first

Before reflashing call Sprint and see if they are doing tower improvements, this can cause that when they are working in things

I'm going to flash stock and unroot to see if that helps. I work 75 miles from my house and have experienced the problem at homd and at work so I'm pretty sure it's not a tower issue.

Try updating PRL and Profile then restart the phone? That may help, I mean if it does then you just saved like an hour of resetting and restoring. If it doesn't then you just wasted maybe 2 minutes.

I've tried this with the exception of rebooting my phone right afterwards. I just updated my PRL but I could not update my profile. I got an error. I'm running out of options
I appreciate everybody's help though.

This happens to my wife all the time on her evo lte, trying again 15 to 20 minutes later usually fixes it so she can update profile and prl
Sprint GS3 FAQ THREAD

Happens to me when I shut off data for any length of time....I just reboot...and it works fine

I called Sprint and they couldn't fix it. I switched the network mode to CDMA from CDMA/LTE and it worked flawlessly. I don't know what that means but something told me my LTE and 3G weren't playing nicely. Whenever I go through a 4G area, it works to perfection. Then I get back in a 3G area and back to the same old thing.
I forgot to mention I flashed to stock unrooted and it seemed to function better but the problem still existed.

I have the same problem I have no idea what to do. I have a custom ROM the only way I get it to work is when I toggle Data on and off really fast. I didn't try the CDMA only though. Either way it's no excuse why our phone's are acting like this.

There was a DATA_HANDOFF.ZIP floating around somewhere....it was made for AOSP but if you make a backup and flash it, it might do some good

I had the same problem. In your phone key pad enter ##72786#. Its going to do hands free activation, prl update, profile update, firmware update (at that point you can cancel)

Same thing started happening to me a couple weeks ago. Tried everything. Only "fix" was setting network to CDMA only. Frustrating.

Need help with RIL File..

Can anyone help me with the RIL Stuff on the G Pro? I have service issues in a low service area but ONLY when using a NON AT&T Stock rom. When using CM 10.1 or the Telcel E980h my service sucks! From around -90 to -100 on stock to -100 to mostly -105 to -111 and its terrible! but When on Stock the network is flawless. Yes Ive tried flashing the Baseband still same problems.
So now the next thing to try is the RIL stuff which I DONT have exspeicance with. How do I get to the RIL files to copy them so I can put them on something else?
The ONLY RIL file I found on stock is under /system/lib/libril.so or something like that but that did nothing.
If its the RIL causing problems how can I fix it?
If its not the RIL that would cause that what else do I look into??
I also wanted to add at this location the phone NEVER looses service completely! But when using something other than the Stock AT&T E980 Rom It keeps going to emgency Calls only a lot as well!

Okay so now that I see when you're on CM10.1 its the same low service. Its not the RIL files. Its actually AT&T lying to you. I know this because whenever I go to Rangely Co, I have crappy service on cm10.1. When on stock ROM I see all bars and 4G, yet speeds are almost nonexistent and I can hardly ever get a phone call out

Its NOT AT&T Lying to me. The Data and Phone calls work fine and service stays intact! I`m NOT talking about Signal Bars here I`m talking about the actual signal strength, and the acutal Service. While on the AT&T rom I can move my phone around at the location and will it will occanalny qurik and stop working but still never go out of service (Still on AT&T network) On any other rom I dont even have touch the phone and just switch to Emergency Calls only, I know how AT&T fakes the signal bars on there phones software but this is not the case the service itself simply does NOT suck as bad as it does when NOT running AT&T`s stock firmware.
So Im not really sure whats going on.
The ONE thing about CM 10.1 though the Service NEVER went out and was a good bit more reliable than the international stock roms it is atleast usable! But I never care for CM.

I had the same issue when I had my s3 when I was on cm my signal sucked but when I was on a touch wiz Rom it was fine could never figure it out tried flash in different modems that did not work either
Sent from my LG-E980 using xda app-developers app

The ROMs interpret signal strength differently. That's why I said before at&t stock ROM is lying to you. It happens to me all the time. When I'm in Rangely on the stock ROM it'll show that my signal strength is strong but it actually isn't because there isn't a tower for them there yet it shows I'm connected to them. However on any other ROM it shows I'm roaming.
Its because the ROMs are designed to read differently. That's why I say at&t ROM is lying.

I understand what your are saying, But its its NOT that causing my issue, as when on AT&T Stock Rom, Calls GO THROUGH Data Works almost with an issue! (not looking at the signal bar and such) On the Telcel rom or anything else, Calls Fail, Calls get Dropped, Data just sits there, Phone looses complete service and says Emergency Calls only!

Have you tried turning on data roaming?

Yea, But that shouldnt do anything as There is NOTHING to roam on here, The closest Place that I have even roamed before and even by Coverage Maps is about 5 hours away Near Nashville, TN but thats the ONLY time I have ever roamed. Sadly even though T-Mobile is here it wont roam no phone has its always emericancy calls only.

[Q] Issues with O2 Mobile Internet (UK)

Hello folks,
I seem to be having some strange issues with mobile internet on O2.
I have been with them since October 2012 when I got the GN2 and everything has been fine up until 1 maybe 2 months ago when I noticed by phone was connecting to H+, which I had never seen with O2 in my city before. Normally it would always be on H, or occasionally 3G... both of which would work no problems. Now, I know what the different connection types are, but the problem is that now whenever it’s on H+ mobile connection around 80% of the time it’s either super slow, or simply doesn’t let me load any web pages or refresh any apps that require data connection. I often have to search for the network again just to get it to work. When it is still on H or 3G everything is fine... it’s just H+ that seems to be causing problems.
Also, around two or three days ago I also started having problems sending and receiving texts.
I’m on Wanam v2.9 with old DLK7 modem, however I was using this long before the problem first started so I don’t think it’s the cause. APN settings are same as always and I took the SIM card out, cleaned it and made sure it was in properly but all to no avail.
I will try calling O2 later, but their customer service is notoriously crap so I thought I’d ask here first.
Cheers,
Lee

Signal dropping constantly

So my mom has this phone, and me and my sister have HTC ones. Our phones work fine at home, and we just got Lte coverage a few days ago, so that's been nice. However, my mom's phone recently has been dropping basically every call no matter where she is or how much service it says she has. The signal bars show a red x, and usually given time the service will come back, but sometimes it takes a restart. I've tried updating profile and prl, and the best the people at the sprint store could do was tell me that there is supposed to be a software update coming to fix it. The phone is completely stock. It doesn't seem like the network cause the other phones work fine. Has anyone else had this issue? Any ideas on what we could try?

You must have weak LTE signal. Go to Settings>More>Mobile Networks and tick it to CDMA. If she wants LTE she'll have to do this manually.
Sorry but it's just the way this phone is.

You can try to flash the ZVC radio from here. http://forum.xda-developers.com/showthread.php?t=2230106 but you'd have to root/unlock.
Other option is to LGNPST in the same thread under "Additional info". That's about all I got.

[Q] At&t S3 On MetroPCS LTE/TmobileLTE

Hi guys, i have a s3 i747 that has been unlocked and ready to be used on other gsm networks.
I went to a metropcs store and had the phone activated and sim card inserted, my imei was connected fine and everything went great.
I instantly had EDGE(1x or 2g) and even after hours of searching and phone calls to metropcs all i can find is APN solutions that dont work.
I currently live in Dallas/Ft Worth so i know the LTE coverage for Metropcs/Tmo is amazing it just ill not connect to LTE.
How do i get LTE to work on this device ??
Phone Specs
Has root
Unlocked
S3 i747 from At&t
Worked fine on At&T for LTE
Su keeps for closing at start because it says security issues
Stock rom on 4.3 but it says custom build under about settings for some reason.
Data speed is about 0.09-0.10mbps
Any help would be great. Sorry if this is a repost of other types of threads but i never found answers and did not want to re awaken old threads.

This issue seems popular this week.
If it's like the others, it's an issue from unlocking. the nv file gets damaged. The solution so far is to use nv-reader-writer to copy another phone's nv file and replace yours with it.

have you tested *#*#4636#*#* method? just mess around with the preferred network and see
I'm on Tmobile and worked fine with LTE

Where could i find a nv file for the s3 i747?

Sir, i tried to use the nv tool but it keeps saying phone wont connect.
i have the drivers installed, it sees my ports for the phone, i go to connect and it does, but when i click read device it fails. Ive had no boxes checked, one box checked and both boxes for spc and fast read(i think it is) checked. No Go either way. Any suggestions for this? Then i can see if the NV Writer is a solution. Also i can use my own NV file right??? Or would that just be a corrupted file being reloaded ?? If thats the case how do i find a clean NV file for a Samsung Galaxy S3 i747 for AT&T??? Thanks again for the help brother

I would think you would need to load an NV of a different s3. I will try to load my NV here in a few and see what happens. PM me also

Ok guys i tried some settings. a guy i know tried to inject the AWS for Tmobiles band freq. and it didnt work.
SOooooooooo im thinking we might have to skip AT&T phones on metro/tmo and get a tmo phone or a AT&T phone that supports AWS band freq.

Wait....How are you getting 4g ?? it might not be LTE but da*m its faster than Edge. Could you tell me your apn, and your settings if you changed anything since you first switched to metropcs.
Like dial star, hash(number sign)twice, the 4636 and star,hash star, hash and go to device info, then screen shot, then scroll down and screen shot again where i can see "set preferred network"
also man are you sure you have the S3 I747 from AT&T??

Make sure you are checking your connection in Settings > About Device > Status > Network Type
You cant always trust what's displayed in the status bar. Especially when using a custom rom or using a device on a different network than it was intended for.

Yea man I know. I've checked everything and says edge still.
I think it's based on your radio and kernel. Brad what kernel and radio you using.?
I'm on 4.3 Rooted and stock.
