LTE fix for Android 4.3

Greg Leaman

I had found this flashable zip to fix LTE on Ting on Android 4.2.2 ( http://forum.xda-developers.com/showthread.php?t=2204334 ), but it doesn't work on Android 4.3 due to /system/etc/apns-conf.xml going from version 7 in 4.2.2 to version 8 in 4.3, whatever that means.  So I pulled apns-conf.xml from CM10.2, made the same changes to it that t3rmin made to the xml from his zip, and blammo, 4G!  Please help me test it!

    Worked for me.  Thanks!  I think the real solution would be to get this merged into the builds (assuming it wouldn't conflict with the actual Sprint APNs).  I found this JIRA issue:   https://jira.cyanogenmod.org/browse/CYAN-960

    Glad I could share the wealth!  My guess is that Sprint customers would be adversely affected by merging in our APNs.  Oddly, I found that stock 4.2.1 on my gnex could connect to 4G without doing anything special.

    Tim, flash it from Clockworkmod recovery just like any other zip. Other recoveries should be fine too.

    I've never flashed my phone. Do I need the Cyanogen mod before I apply this? I assure you anything that I type that may appear that I know what I'm talking about is just because I've been reading to try and figure out what to do to get this on my phone.... and by the way I have no idea what I'm doing. None zero

    Ok, let's start from the beginning.  You have an S3.  Is it rooted?  What version of Android are you running at the moment?  Is it the stock Android or a custom ROM?  You get 3G, but never 4G?

    I can't explain why you don't have 4G on the stock 4.1.2.  I have a Galaxy Nexus and had 4G on stock 4.1.2, but after I rooted and installed a custom 4.2.2 ROM, I had no 4G unless I modified one of the system files, which someone on XDA had discovered.  When I updated to a 4.3 custom ROM, the previous modification didn't work and I came up with a new modification.  The subject of this thread is the modified file to get 4G working on custom 4.3 ROMs.

    Regardless, you can't make use of any of this stuff without being rooted.

    I had the same problem with the stock ROM. The profile update sent when activating a BYOD Samsung Galaxy S3 on Ting seems not to work with LTE. My solution was to install CyanogenMod and then to flash the update provided in this thread.

    I don't know whether the update here would work if flashed onto a rooted phone with stock ROM.

    I want to say it would work with stock and rooted 4.1.2.  But once you're rooted, who wants to stay on stock?  IMHO

    well eventually I need to root this thing anyway. since I'm no longer with Sprint & this is a sprint phone. get rid of all the references to sprint & all that garbage that they loaded on this thing that can't be un-installed.

    I wonder if a factory reset would do it? What sucks is I thought this would be pretty effortless. Or at least once the troubles started that my phone wouldn't be the problem. But now I'm not getting 4G and my wife's phone which I believe is actually a lemon tied to a tin can, aka the HTC Evo 3d, will not even go past the first step of the carrier wipe because somebody changed the code or something because the one provided does not work. So she has no phone except for wifi. I have no 4G and I cannot text which doesnt matter cuz she cannot get them anyway. Seems that Ting tech has given up on that phone telling me that I'll probably have to buy a new one since the one we have is been tampered with and the only other person who had this phone was the tech at Sprint. Who gave it to me when the first lemon started to smell funny and rot

    A factory reset likely won't do it.  If you're willing to lose everything via a factory reset, just bite the bullet and root right now.  I don't know specifics about the S3, but I've rooted many a device.  Follow directions to a T and do your homework so you somewhat understand what you're doing.  The risk is very low.  There will be everything you could possibly want here: http://forum.xda-developers.com/forumdisplay.php?f=1691 .  This looks like a good place to start: http://forum.xda-developers.com/showthread.php?t=1963812 .  You'll have so much more control over your phone after you root, it'll run leaner and faster, and you can run whatever flavor or version of android you'd like.

    would rooting save her phone? That Evo 3d? Thanks for all the info

    I can't say 100%, but I'm inclined to think that rooting could solve your problem with the evo.  Couldn't hurt, it's not doing you much good right now as it is.  We should carry this conversation over to xda-developers.  PM me (poo706).  If you don't have an account, go ahead and make one.  It's the best resource for help and information.

    Ok. It might be a bit. I am slammmmmed w work right now. But I'll drop you a message soon hopefully.

    Scratch that auto-root link I sent you.  Check out this video, it details 3 different ways to root your sprint s3: http://forum.xda-developers.com/forumdisplay.php?f=1707#root .  You probably don't have to worry about increasing the flash counter since I'm guessing you can no longer take the phone back to sprint for repair anyway.  Once you root, you'll be able to modify the system file to get 4G working on Ting, definitely if you move to a custom 4.2.2 ROM or 4.3 ROM, and probably if you want to just stay on stock.

    Thank you so much for this. For some reason I had stopped getting any data connectivity a couple of days ago. Figured since it was already broken I might as well update from CM10.1 to CM10.2 on my GS3. Your flashable zip got me up and running with data connectivity in no time.

    I believe it depends on what version of Android you're on.  Best bet would probably be some app from the play store.  I'm not the best person to ask, rooting is always the very first thing I do.

    I recently got a GS3 from ebay as an upgrade to my Epic 4g. I rooted cyanogenmod and ran into the problem of no LTE. I just wanted to say thank you for this post, it saved me a WORLD of pain.

    Ditto that.  I'm using a 4.3 ROM on my Gnex and had the same issue with no LTE. Ran the 4.3 LTE fix script and boom... 4G -- instantly.  Totally awesome work!

    Has anyone tried this with Android 4.4? I'm running CM10.2.1 on my SGS3 and was thinking about making the move to CM11. Did the APN version change from 4.3 to 4.4?
