4G question - Sprint Samsung Galaxy S III

OK this is pissing me off so much but I used to have 4g then it went out and had 3g it would do that like every 2 weeks and now (I know it sounds weird) I have to bring the 4g in like if I go to the corner block and pick up 4g and go back to my house it will stay till new reboot then I will go back to 3g I just want to know what's going on? Is there a fix ? Or is it normal
Also I have 2 more questions
How the hell to I fix the lost and found error on twrp? It bothers me
And finally I can't transfer my back up to my laptop like only 2 files will copy I can't also transfer it to my SD card it says root permissions required!
Thanks in advance if u reply ^_^

Well first of all Sprints 4G coverage is rather spotty right now since they are still making progress on their massive network upgrade. So yes it is probably normal.
I am not sure of the error you speak of in TWRP but I am sure if you ODIN back to stock and re root and install TWRP again everything will be fine.
And I assume the backup transfer issue is also related to the problem you are having with TWRP.

Instead of walking down the street to pick up the 4g have you tried just toggling airplane mode on and off and seeing if it picks up the 4g.

Yeah I have tried airplane mode and I don't go down the street to pick it up im just saying when I walk back from the store I pick it up

It's just because Sprint is making incredibly large expansions in their LTE department.

Antenna

Can my antenna in my phone break if so can it be replaced our repaired or would I need a new phone. I have dropped it numerous times with very little exterior physical damage. My 3g download speed is .06 mbps and upload of .07. 4G doesn't connect anymore either.

I have had this problem too with ei22 for some reason it sucks
I would run a 3g turbocharger script and see if that improves it any I'll provide the script and instructions let me find my previous post about this
3G Turbocharger RC 3 : http://db.tt/sHUsSnUr
Download this and run it in script manager found on the market.
1. Open script manager and find the rc3.txt
2. A screen will pop up and make sure that the su icon is green or checked this means your running as root. Hit run
3. The command line will go through its script and at the end it will give you 6 options to choose from to boost speed.
4. There is not best option you need to play with them. So prior to installation you should run a speedtest.net to see what your current stats are.
5. Select whichever option I use epieremental 1, and reboot.
6. Run a test and see if its better
7. Test all of them and see which has the best result for you.
If you have any questions feel free to ask.
If none of this helps then I would take it into sprint and ask them to test the antenna to see if its faulty

Thanks I did that earlier as I read into a post in the Q& A thread where you had given someone that same advice. It might not be my antenna because I went to Lunch and I had better signal elsewhere other than work. I've never had that problem before with my service at work. Also when I tilt my epic counterclockwise I lose signal. So maybe it its my antenna.

It is also possible if your cell signal is very erratic that you have damaged the antenna connection. More than likely it is issues with a tower near you. Odin back to EC05 and see if 4G works again. Check with other Sprint users near you to see if their 4G is working.

If it is the antenna, Sprint will replace it. $35
I had my 4G go bad after jamming a copper wire in to far on the 4G port on the back killing the internal.
I've checked with other sprint users and there 3g is fine and they connect with 4g. like I said I got better 3g reception when I left work but still couldn't get 4g to connect. My wifi works great when i'm at home.

If it sits there and tries twice with no go and there is 4G. Then it's probably the antenna. It can just brake like that when dropped. Sprint will take it and turn it on. If it doesn't connect then they won't even question you. $35 new phone. well... refeb but you get the idea. If everything else works and it tries to connect, I wouldn't think its the modem or software. In those cases it will lockup or start force closing. But... It work, you dropped it, it doesn't work.... Antenna or like. There really isn't to much to do to fix it either. Do a CWM backup, get the new phone and restore.

Then you should Odin back to EC05 and try it there. I lost 4G with data corruption once. Putting it back to stock fixed it, restoring data broke it. Manually restored my phone after Odining the second time.

Thanks I will try to Odin back to stock and see if that helps if not then I will go up to the sprint store and have them check it out.

plus you have to odin either way before you take it up there so... Good luck! Let us know.

Yes, that is best, and head straight to Sprint while still on EC05 unrooted. Then they can't blame it on rooting or software.

4g lte not working

I am running the latest cm10 nightly and I haven't been able to connect to 4g lte for the last week or two. Is anyone else having this problem? Has anyone found a solution?
Sent from my SPH-L710 using xda premium
Which market are you in? There's a chance that the tower was only on for testing and has since been turned off. There's also a chance that another tower closer to you is currently being upgraded, so the phone is trying to connect to that tower's LTE, getting rejected, and falling back to 3G. That's what's happening to me, and it's frustrating because I had a steady 4G signal for a week and a half, then one day, it refused to stay connected to 4G for longer than a minute. Now, I just have to wait for them to finish the new tower.
The reason could be just about anything depending on your market.
I am in the Atlanta market which has been officially announced. Friends that live nearby have not been having this problem on stock ux software. I was wondering if cm10 has a big or something?

Actually, it has a couple LTE bugs. CM10 doesn't currently handle 3G/4G handoffs properly, so that could be part of the issue, but it holds a 4G connection fine if the signal is strong enough, at least from my experience. Another bug is that it will just stop making connections, and you have to wipe data to fix it. Have you tried toggling airplane mode? If that doesn't work, make a nandroid and try a clean install of CM10. I had to do that recently because it completely stopped connecting to 4G and barely connected to 3G. As soon as I booted up, 4G was back (didn't last long, but I explained that in my other post). If wiping data doesn't work, flash to TW and see if the problem persists. If it still doesn't connect, then you may have a hardware issue, but I think that's unlikely since it was working for you before. You never know, though.
Keep in mind, even though Atlanta's been officially launched, it's only about one third complete, so lots of towers are still being upgraded. It's possible you're facing the second issue in my first post, like I am. If so, then just concentrate on how much better it'll be when the new tower is finished.

Happened to me several times. The best thing you can do is make a nandroid once you get your favorite AOSP rom set up to your liking, and restore to it once LTE stops working. I tried to get myself to go to TW but its just so slow
What is TW?

I have a similar issue. If i go into settings, about phone, and status I pick up LTE:13, but I get no connection or IP address so I have to change over to 3g. Is this a known issue, and if so is it being addressed? I am currently running nightly 10-14-2012 if it helps. Thanks
Edit: I've tried TW and it works just fine there. 14 down and 6 up.
Its likely to do with cm10. And the handoff issue like it was explained a few posts back. I love cm10 but data would work if u was lucky for 2 hours out of the whole day. So I'm on the leaked lih build. Just gotta wait patiently for the great devs to figure it out.

Getting really slow data...

For some reason lately I've been getting only Edge in my area when normally I get extremely solid H+. I don't know if my phone is acting up (completely stock on 4.1.2) or if AT&T may be upgrading their network in my area, possibly adding LTE. Any ideas why?

Sent from my SAMSUNG-SGH-I317 using xda premium
Let us know if it doesnt work. It happens. If youre getting it a lot. Thats not usual. Or if it happens in your house fron 4g down to edge. It could be an issue with your tower. Or location. Maybe the tower is overloaded and they kick you to another?
This has happened to me once on this phone. And it was on either stock rom or blackout. Cant remember
Sent from GN2 using XDA app
Well where I work I get full signal. Averaging 10 Mbps down on H+. But recently I've only been getting Edge. It could very well be what you said about too many users on one tower. I'll try tomorrow and let you know.

A few months ago when I had my Galaxy S3 I got this problem out of nowhere. I never found a solution even tho I tried going back to stock and several other "fixes". Ended up having to send the phone back and getting another one. Idk if the antenna went bad or what but even on Edge it was unresonble slow
Well I couldn't hold myself back the other night and I flashed Jedi X. Haha. Having no data issues now.

I'm forced to use HSPDA due to the LTE network being overloaded here in SoCal.
Funny thing is, with LTE on, I avg about 3down/10up....with HSPDA, I get roughly 6down/1up. Quite frankly, I care more about download than upload anyway so it's actually better for me

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.

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.

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.

HELP, no connection after flight from NC to TX

Hey all,
I could really use some advice. I live in North Carolina, my phone has worked just fine for over a year. Monday I went on a business trip to Dallas Texas and my phone won't connect to Voice or Data services at all. What can I do?
I tried turning airplane mode on and off, removing the battery, chatted with Sprint online, called the Support number. Sprint is NO help at all. They didn't outright tell me that my phone was broken, but practically did. I guess it just magically broke on the plane to Dallas??
Even in areas with good coverage, like my bars show good connection, I can't connect. I can hook to wifi just fine, but that is it. Sprint support told me that they can't even see where my phone has connected at all since I arrived in Texas.
Should I try flashing one of those PRLs from another thread? I'm not sure what to do. I assume that as is my phone will start working again when I get back to North Carolina though. I tried reflashing a "stock" rom and some of those "#" number calls, but none of them work since my phone isn't connected to any towers. Help!
Did u by chance try ##72786#? That's the hands free activation. Will turn ur phone off and should boot back up after a few seconds

That is what is so strange, I can dial that number, even from a stock rom, and my phone doesn't do anything, it just sits on "dialing" then makes the hang up noise after 15 or so seconds.
That's definitely weird! I'm from this area so I know it's not the water...lol. Have u taken to an actual sprint store?

Not yet, since I'm here on business I don't have much time to do that, but honestly I don't think they would be able to do much more than the support person over the phone did. I'd have to unroot it and all of that before bringing it in, the folks in the store would try those ## type calls, wipe my phone and reset it, then probably tell me my phone is broken and try to sell me another phone, especially since I am eligible for an upgrade.
I don't want to actually buy a new phone until I get back to NC since I still think my phone will start working once I am back there, which would be just as confusing.
This is the same phone I brought here to Texas last October and it worked fine, so I don't know what exactly the issue could be.

If you are still having this issue I would suggest you try an app called Network Signal Refresher. It basicly updates your prl and profile by connecting you to the nearest tower

Thanks, I gave this a try, but it doesn't look like it worked. Part of the issueI think even for PRL updates is that my phone won't connect to the towers. Like with a Stock Rom in the Sprint Zone you can get to that section where you can do a Profile update and all of that, it always fails with a connection error. I gave that error message to Sprint support but they couldn't do anything with it. I will keep trying it though now and then.

Is there a good updated guide for doing that? I did that on my EVO 4G, but never on the S3. I haven't looked yet but I will check into it this evening for sure.
They could be working on the towers in the area. When they did in my area, it showed I had bars but could not text or call. I would try flashing the 2 PRL, as it helped me get my phone working until they fixed it or in your case until you get Home. I can upload it if you need it.
