[Q] Unable to get 4g

Alright, I'm a flash addict, love trying all the roms and well I was switching from bamf 2.0 beta 4, to Gingeritis VIII. I did my wipes and everything special, yet when I finally load it up, my 4g is not there. I'm in a 4g area, and I can get 3g but not my normal 4g. Not sure what to do, I even tried restoring back to my bamf rom with no luck. I had it before I did the switch and it was working fine. Anyone else having a issue or know what could be causing my problems? Forgot to mention I did try changing the radio settings and doing a fix permissions, neither did anything.

Did you update the radio?

Have you called Verizon to see if there is an outage? My 4g went down for a few hours yesterday, might just be them working on the network.

Radio was updated and I'll give big red a call, I mean its kinda odd I hold my 3g easily yet my 4g dies. I've had my 4g all night, and it did happen in the morning, so maybe they are working on it.

Called big red and they told me it would be back online soon just a short outage in the area. Came back online as I was typing this lmfao

Everyone needs to remember, VZW is constantly upgrading/testing/fixing their LTE network. Things like this will be going on most likely all year as they continue to roll out to more cities/markets. First thing to do if your 4G starts acting up is just give them a call. More likely than not, they are doing work, it's just coincidence that it stopped working right after a flash

Yeah I can't get 4g to work either. It might be because I don't have it yet. I figured I would just flash rom after rom till I find one that works.
Just trying to get past 10 posts.

I am also in a 4G area (Los angeles) and had 4G all the time but when I upgraded to the Gingerbread leak I lost it and yes I flashed new radio, its been about a week now. Haven't called big red yet and also haven't heard of updates in my area but 1 week, that's a long time. I also reverted to froyo with accompanying radio and no change...wondering if anyone else in LA area has the same problem or do I have a problem with my phones hardware...

Be sure to reboot the phone like 5 times. That brought it back for me.

I haven't had any data since friday afternoon. I had it connect to 3G earlier this morning but it promptly disconnected.
I've tried rebooting since friday. Setting to CDMA, enabling Rev A from ##778. Still nothing.
I'm on the launch stock rooted rom.

I called tech support and let them know of the issue, said there is no 4g outages in my area (los angeles) and was instructed to factory reset, which i do before any rom install then i gotta call back-if and when i get this resolved i will post the outcome.

Not sure what rom you're on now, but whenever I flash something if I lose data I have to go into the antenna settings and force 4G for a while and it will pop back up

I'm still on Baseband 1.16.00.0223 and Software 1.12.605.6
Could it be since i'm rooted and have not applied the OTA, that verizon is refusing to authenticate my data (connection)? Because when i look at lteonoff, it says i'm connected to whatever network i specify, (LTE, CDMA - eHRPD OR Rev. A [if i go into ##778])
If I go to options ->software update -> check new, the 3G or 4G icon will pop up and checks for a newer firmware. It tells me there is a new update and i can press okay, defer, or deny. As soon as i exit that and try to use the browser, the 3/4G icon goes away. Should I update to the MR1 OTA?

No, that's not why you don't have to worry about that just yet haha. Try and force 4G by putting it in LTE mode

Im just in a 3g area and everytime I go to a gigerbread rom and radio all I get is 1x. Then reverting started jot even fixing the problem. After about 10 flashes back and forth and rebooting a hung I finally ended up on Froyo with 3g. I'm staying here. Not worth my time to run gingerbread.

I was running a GB rom and this afternoon lost all data.
If I take out the sim card and reboot, I can get data for a minute or two...then it goes again.
I'm going back to stock and taking my phone in tomorrow.

Ugh to the guy that said call tech support to see if there is an outage, I don't work in a call center but do in a store and I hate when people come in or call for outages my suggestion is to follow @vzwsupport on Twitter they will let you know in no time and it keeps you from having to go through the menus and crap.

I re-flashed back to stock and now I've got 4G back.
If anyone is having these problems after running GB I would use JCase's "back to Froyo" flash before trying anything else.

Verizon has had a known problem of thunderbolts loosing its 4g, 3g and 1x. I had the same problem over a month ago when my phone was only able to receive calls and text. Had no data.. so I called them they had me do a factory reset and it fixed it

turn off background data and auto sync then reboot when u get 4g wait a sec then check the internet to make sure its really on then turn sync etc back on back on

4g down or buggered phone?

Im in the DC area and my phone wont connect to 4g for life of me (im in a strong 4g area). tried toggling. tried forcing LTE only(either 1x shows up or nothing at all). tried turning off data for 10 minutes. tried removing battery. tried full wipe (wiped three times cache, tried clearing davlik cache and battery stats...three times) reinstalling 1.7. I can still connect to 3g and 1x. Just no 4g
i was initially on bamf's 2.0b5 and noticed i couldnt get 4g. so i restored back to 1.7 and still no 4g. and no i didnt forget to flash the appropriate radios. i called verizon to see if there were issues with the network in the area and they came up with nothing. is my radio broken or am i missing something here?

Try starting the phone up once without the sim card in and then reinstall the sim card and see if it works.

just tried that. no dice. any other suggestions?

Maybe take it in to vzw and have them test the sim. It could be fried.

whoa. i didnt know that could happen.

same thing with mine I am in Manasasso area and i get 4g off and on but cant get on the market or google, then i back to 1x so is it a phone issue or a system issue.

Well with me its not even on and off. I get nothing at all.
Sent from my ADR6400L using XDA App

I'm sure this is a stupid question but it must be asked. Do you have the back of the phone off?

no such thing as a dumb question. just dumb people. hahaha im kidding. just trying to make light of the situation a little at least. i had a teacher that would always joke around like that so i had to say it.
but i digress, no the battery cover is not off. like i said, 3g and 1x works. just no 4g. can it be possible that just the 4g radio could be broken or if that were the case, i wouldnt have any data network at all?......
and as i was typing this message, my 4g connection had just connected. i think it has to do with the area where i live because I am now in my work building and it seems to be working fine now...i guess verizon lied to me... thanks for the suggestions. will post if things change.

Well, according to Verizon and their coverage map I'm supposed to get 4G at my house but I don't. Granted, I am on the edge. Now, here at work is a different story...solid 4G and it never looks for 3G.

Yeah, I am supposed to have 4g at where I live too. And I would get a strong signal too, which was why I was totally stumped when i couldnt get a 4g connection all of a sudden and verizon told me there were no problems with the network in the area.

this is happening to me as well. Phone keeps jumping between 1X and 3G all the time. I rarely get 4G anymore
I'm on Perfect Storm1.5 running the MR2.5 Radio chingy leaked
I have tried 4 different radios as well as ROMs over this past week, no change on either

been 4 hours and phone hasnt dropped 4g since. even flashed back to bamf 2.0b6. I would get no signal on reboot, but toggling works like usual again. i guess where I live is having problems right now. will post when i get back.

working now. im guessing its the network. running 2.0b6 with mr2.5

This was happening to me as well. I would sometime get "4G", but it's fake 4G, as I would not be able to receive any downstream data, and connectivity would soon cut out. I've gone from GingerRemix 2.1 back -> 1.7 -> 1.63 -> stock -> stock unrooted, and could not get 4G back.
I decided to throw in the towel and go to Verizon (with GingerRemix 2.1 loaded), to compare. They definitely had 4G in store while I was carrying 3G around. I told the "device specialist", and without much questions, he popped in a new sim card for me. I had 4G then until I was about 4 steps out the door, and it would fall back to 3G. The dude and I spent the next hour swapping out another card, placing my sim card into a returned TBolt, but no luck. Finally, he did a factory reset on my phone. With no further luck, he resorted to ordering me a new one.
Still unsure what the issue is since he did give me a new SIM, and that SIM didn't work on another TBolt as well. We'll see whether the new one that comes in the mail tomorrow will fix the issue. I've since then reverted back to stock, since I need to mail my "broken" phone back to VZ, still no 4G.

[Q] G2X 4G Problems

I've had this phone since release and have loved it. I have only one issue with it. I'll be trying to use my internet on the phone and it will show the upload arrow but the download will never do anything. I have full signal so this is not the problem. This happends a lot and in the middle of browsing it will do it... It will load a page and I'll click a link and it wont load and then it will work again after awhile. Does anyone else have this problem? Does anyone know a fix or the reason its doing this. Also I have full 4G coverage where I am.

It happens to me a lot too! Its very inconvenient and I know its not the area where I reside because I also have a g2 on my spare line and the g2s data works perfectly fine when the g2xs is stalling. :/

Did you get yours at release? If so it may just be the first batch or something...

Could be lots of things. Have you activated and are using the SIM that came with the phone. Supposedly the G2x uses a new SIM format.
What OS are you running? Are you on WiFi? 2G, 3G, 4G? Where does this occur?
I surf my with my phone a lot and I don't get that intermittent data problem you are describing. I am running the latest CM7 (#70) and in a 3G area with average signal quality.

I'm using the SIM that came with the phone and this is only on 4G I reverted back to stock ROM unrooted and still has the problem

I've never rooted my phone. I've actually swapped the sim twice already thinking it was the problem. Hard reset has been done. I've pretty much tried every trick in the book and the problem still persists. Its my 2nd replacement(1st one had the same issue)
Sent from my LG-P999 using XDA App

P.s I got the first one at release then had it exchanged(buyers remorse period) for a new one towards the end of may so I doubt the 2nd one was from the first batch.

Like Player said, could be alot of things. For a sim, the G2x does not require a brand new sim, but it does require a newer sim. If your sim is older than 18 months, put in the one that came with the phone. Last years TMOBILE sim will work with the G2x.
Also, data plan. Didn't happen to me, but did happen to my son, the plan was not enabled for 4g Android. He got signal, rarely 4g...but did get 2g.3g. Walked back in the store..asked what was up...they checked...1 mouse click and finished. Funny thing was, he bought the phone from them, earlier in the day. You would have thought they would have covered that.

Your sons phone was showing 3g? Hmm... I thought on tmo 4g was a fast version of 3g and that the g2x only showed 2g or 4g. I am probably misunderstanding something.

So I went to T-Mobile just now and they gave me a new SIM and it fixed all the problems so if anyone else is having trouble try getting a new SIM first....its free

Verizon GS3 stuck on 3g

Second day owning this device and love it so far, but day two has been rough. I am stuck on 3g. All of a sudden today my lte switched and will not go back. Iv'e rebooted, toggled airplane mode and data. Even pulled the sim. I live in a strong 4g area so that is not the problem. My buddy has a nexus and his is fine. I also have had great reception in areas I have always had problems, so not a reception issue. I called verizon and was told it is a know issue that is normally solved with a reboot. She said an update was scheduled for early September to fix the issue. The point of this thread is to find out if anyone else has had this problem, or found a solution.
Edit: After countless toggling I got it back to 4g, but it won't connect to the network. So my thought is that the sim card is trashed. Going to get a new sim card first thing in the morning.

Unfortunately I am also finding myself stuck in 3g. I have pulled the battery, installed a new ROM. Still working on it, not thrilled. Prior to 4g disappearing, it showed 4g, however I was unable to connect over it. I hope this isn't a hardware issue.

Did this work?

Just FYI, I have the SCH-i535 and am noticing similar behavior. I had a Samsung Droid Charge before the SGS3, and it stayed locked to 4G LTE in the same exact areas of my home. If my Charge did happen to drop 4G, it would always come back. But not with my SCH-i535. Once 4G drops it stays on 3G until I reboot the phone. So far, this is my only complaint about this phone.

It is very random for me. Im certain its a **** sim card. Right now its fine, but at any time it may get stuck on 3g. Also while at work the first couple of days it would hold a decent 3g signal, now its primarily on 1x. Once i replace the sim card I am hopeful for it to be fine.

I thought Verizon said that this was a known issue? I'm just curious as to why you would disagree. But if a new SIM does happen to fix the problem, please let us know.

Just a heads up! I have the same issue, but I can't get 4g back at all, which I thought stemmed from flashing CM9, but this thread is making me wonder now! I spent an hour on the phone with Verizon technical support and they said you will get a popup if the sim is the issue. They told me its the phone and they are sending me a new one. FYI you can try this code. *2767*3855# in the dialer to factory reset the phone ( can do the same in recovery ofcourse), but you HAVE to be running STOCK UNROOTED! Some people have had luck with this "resetting" the radio I guess. If this doesnt work, might as well call them and get a new phone coming. TRUST ME, I believe I did everything I could think of before calling them, except taking the phone apart and pulling a new radio out of my ass!! Lol

I'd just return the phone and get a new one if possible.

They did tell me it was known issue. Its just weird how random it is. I am hopeful it is either the sim card of a software issue. I hope it is not a hardware issue. I would rather not have my phone replaced as I just put a new screen protector on. Also to those getting a replacement, is it brand new or a certified like new device?

I did read in another forum that the replacement phones are coming out with a baseband update. I'm guessing that we will probably need to exchange our phones...or be patient for the OTA. Hopefully it won't be too much longer. Incidentally, I just did a factory reset and 4G now appears to be working. Time will tell...

I also flashed CM9, and I am fairly certain this was the cause of my problems. Nothing I did would make 4G work again.
Other 4G VZW devices seemed to work fine at the same time(I have an ipad3 for work, POS).
I didn't mess with it for a couple of hours while running errands, then all of the sudden it was working again. Been fine ever since as far as I can tell. It would be nice to know what exactly is causing this, but for now I'd caution against messing with cm9 .

No 4G after 4.0.4 update, T-Mobile

Called T-Mobile up, it is a software bug that HTC is actively working on. In the mean time, I have NO 3G/4G. I'm stuck on GSM 2G. :/
They coughed up the data portion of my bill, which was nice. Is there any way to fix it in the meantime?

I get 4G fine!

Same here. Not getting 4G. Seems like quite a few is experiencing it. Look at the Tmobile support forums for HTC one S.

Flash a custom Rom, get 4g back. At the very least I would root and take a look at the build.prop settings, might be something simple in there. If you'd like, upload your build.prop file so we can check out out

Well... now that I can't downgrade via RUU... :/

Alright, I can't take it anymore. CM10 didn't fix the issue AT ALL. I am stuck on Edge no matter what ROM I'm on.

Here is the thread on T-Mobile's forums about the problem
support.t-mobile.com/thread/33209?tstart=0 (I'm a new user here, can't post links, you'll have to cut and paste)
The problem appears to be specific to certain phones. I tried my SIM card in a demo phone at the T-Mobile store and we updated their phone to the latest version while I was there and it did not have a problem connecting to the 4G network.
I checked the software versions on their phone vs. mine and they all match.
This update contains a new HBOOT and radio update. Because of the HBOOT update, there is no way to roll back to a previous version. I am guessing that the problem is with the radio update since custom roms do not appear to fix the problem. Because of the new HBOOT, there doesn't appear to be a way to downgrade the radio either.
I contacted HTC and they were no help. They told me they were aware of the problem and were working on it, but had no ETA for a fix. T-Mobile told me they were unable to exchange the phone since there is no guarantee the new phone won't have the same problem.

The problem is a hardware issue with the one s.
Turns out a chip is fried affecting your 4g.
Even after installing another Rom, it won't fix your problem.
Happened to me and I got mine replaced.
It's not specific to the 4.0.4 update. It affects non upgraded phones as well.
If your not getting 4g then you got a bad phone.

I was getting 4G fine right before the update. Right after the update, no 4G. Others have had the exact same problem caused by the update. T-Mobile says it is a problem with the update affecting certain handsets. HTC says it is a problem with the update affecting certain handsets.
Are you saying the process of applying the update is frying certain handsets since the problem is only showing up by applying the update?

There is no 4g for the one S because the chipset does not support 4g.
If I helped in any way please hit thanks

I happened to encounter this issue. But my handset was defective because it was brand new and I'm stuck on 2g. I am waiting on a replacement phone. I literally just had it delivered today and it sucks having this problem right out of the box.

That is how mine was. My phone got "4G" (HSPA+) before the update, no luck after the update.

Same problem here with 4. 0.4. Went to CM10 and got 4G again. My MMS doesn't work though

I actually had this happen on the phone I bought directly from my local T-Mobile store last Friday (10/05). I went back in the next day after discovering the thread on the T-Mobile support forums, and they exchanged the phone for me in-store, there on the spot. I have perfectly functioning 4G now, but I'm terrified to run the update for fear of it happening again.
Does any one know if there's any kind of data specifying a certain production run of phones, or anything of that nature?

Are you retarded?

trmacdonal that is not very nice.

And not really in any way helpful.
According to the most recent post in the T-Mobile support thread, HTC is aware of the issue, has no idea what is causing it, and has no ETA for a fix. Glad I went and got another phone when I did, but I'm fairly miffed that I can't update without fear of turning my smartphone in a, well... phone.

Interesting that this happens only after the 4.0.4 update. I'd like to keep my fast connection; is there a way to keep the phone from downloading and applying the update?
I had a similar issue with my HTC G2 two years ago. HSPA icon appeared, but only one arrow would flash; no connectivity. I could connect to the Internet only using 2G and WiFi. Some devices had the issue, others did not. It lasted for about a month or two, then the issue magically disappeared. Perhaps they rolled updates when the problem occurred and resolved, I'm not sure. If I disabled WiFi on the G2, sometimes the HSPA would connect; there seemed to be an issue switching from WiFi to HSPA. Unfortunately, it sounds like the One S has a slightly different issue. I'll continue to monitor this thread and the one at support.t-mo.
