If you do everything posted in the link above and it still happens your area could be going thew a 4g upgrade. I had that happen for a month and ahalf and it just one day stopped, and 4g was fine again.
Double check with sprint or other 4g users around your area to see if they are experiencing the same.

Sprint is that way, dear.
Sprint puts out a 4g map, where it shows you'll get Indoor and Outdoor, Outdoor/Street only, and the map is extremely specific and detailed.
For example, my whole street in in a band of "outdoor only" 4g, and once you go indoors, it connects then disconnects, connects then disconnects.

4G network down in Denver, CO?

I haven't been able to connect to 4G for a few days now. I'm not sure if my phone is malfunctioning, because I don't know anyone else with 4G to confirm if there is actually a signal to connect to - has anyone else noticed any problems with the 4G network, particularly near Denver?
The 4G symbol shows up and the phone looks like it is trying to connect... When my radio hardware failed on my first Epic, it wouldn't even do that much, so i'm hoping it is the network and not my phone

i know for a fact that 4G works here in Aurora. Hasn't failed me once. Occasionally it won't connect but nothing a radio reset [airplane mode] can't fix. Usually its the phone that has issues. For me at least

We're talking about Wimax 4g

I'm running SRF 1.2 with Genocide 1.2 (or maybe 2.0, I can't remember which one I flashed last time, lol), with the EH06 modem
I think I'll try a full wipe and reflash, because I think I had this problem once a long time ago from a bad flash...
EDIT: I also recently noticed that my
signal keeps dropping to zero bars, although the 3G symbol is still there... Maybe I'll start with a modem swap...

runnin the EH06 modem as well, so I guess once i escape this shielded cage of a building i'll find out if 4g works.. haven't tried 4g since i flashed the EH06 modem..

Im running SFR 1.2 (in the Tech Center) using the Genocide kernel. Not having any 4G issues here.

Just got a chance to test 4g.. and it's workin fine.. (otherwise this wouldn't show up...)

4g is working fine up here in Northglenn/Thornton

4g working for me in N. Denver and everywhere else I normally get it around town so guess its time for you to re flash .

I'm at denver airport I'm guessing 4g is not here??

Well, thanks for all of your feedback - I was facing the hard decision between a long phone call to tech support or a full reflash.
I had to Odin all the way back to DI18 and rebuild from there to get my 4G back, but it was worth it

Never got 4G on Sprint (HTC Supersonic)

Hello everyone, I hope to check this thread for updates (read: I'm so dumb I don't check for thread updates often *laughs*).
Anyway, as the title says, I never got 4G on my phone, even before rooting it! I obtained this phone, new, around the time Sprint (began) started adding a extra rate for all smartphones (read: all smartphones will be more expensive than "simple" phones on same plan).
I'm wondering how to get 4G on my phone that is running Cyanogenmod. I am well-versed in Linux, so if the adb shell or the bootloader is required to fix, I can follow the steps you provide. Or should I just accuse Sprint for giving me a defective phone those many, many years ago, even though I never got 4G in the first place? (since my phone is rooted atm, I doubt I could win a court case.)
I appreciate any help, even if you do not know how to fix this. (read: asking around or just reading this)

4G and wimax are the same thing if you didn't know.
And OP, if you are on an ICS Rom or a JB Rom, you will not have wimax. For all you know, you might not even have 4G service in range of where you live. I personally have never even connected to a 4G network.

i'm referring to the standard 4G pn Sprint (or whatever 4G was said to be had on "Sprint HTC Evo 4G" by Sprint)

From my understand wimax AND Lte use different radios hence why any of the new lte phones like the GS3 or evo are stuck on 3g network until LTE rolls out in the area you live. Also he stated he couldn't access 4g even before so he would be on a stock gb

They are not putting up old towers just lte transmitters. They use all the same till they discontinue 3g.

And if you never have been able to get 4g then I would have brought the phone back to sprint. All their 4g phones should access it if your in the coverage zone.
Sent from my PC36100 using xda premium

If you have had the phone for more than 6 months, which it sounds like you have, you should un-root it and take it to sprint. If that is you want 4g service. The unrooting process is generally about the same in difficulty as rooting the phone was, so if you figured that out you should be able to get it backto stock. The process is different depending on your HBoot version and how you rooted it in the first place. If you want to get your 4g fixed, post your HBoot version and root method and someone will point the way to unrooting the phone.
(to get the HBoot version, pull the battery, put it back in, hold vol down, and power on the phone. You should get into the bootloader and the HBoot version should be listed there.)

I assumed it was due to not having the 4G plan before that caused my phone to never get 4G with the plans change (read: Sprint changed plan details). I should of thought of turning it in sooner, but I was not 100% smart back then (nor will I ever be *laughs*)

I would bring it into a store and get it tested to see if it works after you unroot, my sprint store doesn't care about root but that might not bevl the case. Then if it really doesn't work I would ***** and tell them to look up your account to show you never used 4g and see if the will give you a comp on your account.
Sent from my PC36100 using xda premium

I never noticed any difference in speed the few times I was in California where there was 4g. I live in AZ and with sprint there is no 4g service but we still pay the fee :/

I doubt unrooting it will fully unroot it (I did edit some startup scripts since i've rooted which seemed to have no impact on my data connection (mostly for ext2 mount point on a directory "/mnt/sdcard/sd-ext" which I removed due to delayed sdcard mounting--now I use a script I manually run when I want to ... offtopic sorry >.> ), so idk if a full unroot is possible.
EDIT: *scrolls back on posts* I read that flashing someone else's radio (backed up from their device) can prevent both from using 4G at the same time. tbh, I don't know if I ever did (I hope not)
Sent from my HTC Evo 4G using Tapatalk (ex-GetJar version)

*hopes this doesn't count as a double post*
Somehow I'm getting 4G atm... but it is in a place I tried before (many moons ago). Strange indeed.
What I just don't get is why it is now working. Did I really flash someone else's Radio? If so, was someone else with that "4G login credientals" always on when I tried before? If not, was Sprint lying to me on their online map for 3G/4G coverage?
EDIT: I want to leave this open to see if anyone has any idea as to why it was failing. Another strange finding is that it is a 1 of 3 bars 4G signal according to Cyanogenmod's standard indicator. ( +1 for tethering without having to pay over $100 USD total on Sprint)

I've never had wimax signal at my house. Or city.
We are listed as 4g service area for "clear" wimax broadband, but they also state that it is currently not being sold here. That tells me the switch hasn't been flipped on it yet.
There is no sprint wimax one city over but they flipped the switch on "clear" broadband wimax and it's FAST.... If I get signal (its very spotty) ... . 7.4mb down. 1.14mb up.
Edit:
I was searching the intarwebz and it looks like anything more than 2 miles from the tower is pushing it for signal.
I also have the understanding that the 10$ smartphone fee is not just for 4g, but more so the nature of the beast. We have always on, always connected/pinging data devices.

[Q] Anybody have working Wimax around Seattle?

I have flashed numerous ROMs and none have had working Wimax. I am in Everett/ Lynnwood and can't get wimax to even to last long enough to measure. I have tried a number of modems as well. EL 29, FF18, FG20 and even the newest one which was available thru the goodness updater. By the way has anyone figured out how to measure Wimax? I used to have the Evo 4g and got a great signal and the Evo would tell you if you had good or poor signal, however I have not found anything to measure 4g speed on my E4GT and without 4G I can't do the adjustments suggested in another post.

Thanks for the heads up on that, right now I am going through the different modems to see if one of them will work. Is it possible this E4GT is a dud? Although my daughter is still on stock EL29 and she has bad Wimax as well.
I did notice that if I kept toggling the 4g and ran a speed test that I sometimes got better results - so far I am at FC14 and sometimes I get 2+ mb down with a ping under a hundred. My area of Seattle sucks, as I just tried Clearwire and am sending it back as well. Does anyone know of a good app that will measure the wimax, the one one the E4Gt doesn't work very well compared to what HTC has. Well I have been working on this for quite a while so time to crash

If you go to settings than go to 4g it shows you your connection in bars like back on gingerbread. If you want to get a more accurate reading than ##DEBUG# is your best option. It gives you your connection status in dbm. Lock code is 777468 not your msl. You'll find it in Wimax DM.

In that same menu screen go to Wimax CT and click open device. After that scroll all the way down and click on both the load default and odb load default. This resets 4g back to default sprint values. Try that and then try turning on 4g and see if it works. Lil hint clicking on Wimax IP in that same screen will automatically start up 4g

Thanks to everyone who had advice for me. Took it to the store and they gave me a new refurb with working 4G, ain't Sprint the greatest, the tech told me that things burn up on the boards all the time, that I probably got the battery to hot or that the 4g part of the board just died for no particular reason (last billing cycle I did 4Gb of Wimax and 3+ Gb of 3g - that is why I stay with Sprint lol, no throttling and no warning call or text)

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.
