Can't keep LTE signal - Sprint HTC EVO 4G LTE

I seem to be able to pick up an LTE signal all over KC but can only hold it for a minute or so, then it goes back to 3g and never picks back up LTE while I'm in the area. Anyone else having issues like this? Anyone think I have a bad unit?
Thanks

It's currently a problem with the EVO

Not just the EVO

I just got a new Evo yesterday because the old one died out the blue and wouldn't turn back on. The old one was rooted /with the new firmware & running that mean Rom. I rooted on the 14th of July & I live in Atlanta, so when they made 4g available I saw it in my status bar and was very happy .Then seconds later it was gone.On top of that my phone was super slow and not impressive anymore. I thought the root /rom/firmware screwed something up. But ppl told me know firmware updates help and mean Rom is the best Rom ..Well anyway I'm at home right now on my phone ..no root ..no Rom ...old firmware and sometype of way the 4g LTE signal is holding strong. I'm getting like 12-15 down & 11 up and I'm in the house. Usually in the house I got like 5-11 in the house depending on location. When I'm outside it goes much faster. But I don't know just something I noticed.

4G or not?

So I don't live in a 4G area. But yesterday while at work I noticed I had a 4g signal. Did speed test and downloads were great. Now today I'm not reading a 4g signal, what gives? By the way I did root my phone last night, you think that has something to do with it?

Verizon tests the 4g and turns it off...like a trial.. i wouldnt be suprised if you saw the signal today and it went away again
Also, they are rolling out dozens of cities in the next few months, and I don't know that their coverage map will necessarily be kept up to date. You could end up in a 4G area before anyone bothers to tell you.
Well I hope they turn it back on soon. Nice to have 4g at work. Maybe I should go find the switch and turn it back on!

4g/LTE issues

So my phone will not connect to 4G at all anymore. I have wiped and flashed Virus rom, Bloatless rom, Mik Rom, etc, and it may show the 4G lte icon, and then kicks off and goes to 3G. Also if I tell it to go to LTE only, it won't even show an icon at all.
I might be exchanging my phone out tomorrow anyway for some nasty backlight bleeding mine is doing, but I just wondered if anyone had any ideas. At first I thought it was because I removed some stuff I shouldn't have, but that went out the door the moment I wiped and flashed a new rom.
*EDIT* guess I should go ahead and point out that when it does "pretend" to connecto to 4G I have 3 bars, and have had 3 bars in this location since I got the phone saturday. So it isn't a signal issue.
Are you in a stable 4g area? I flashed MikRom tonight, instant 4g, plus, download speeds were in the 12-14mb range, which is as good, if not better than stock rom.

Yeah I just corrected my post. I have seen speeds near 30 down in this location, and usually have 3 bars. At worst I was pulling 10-12 down. This just started happening today, but I am not sure when. I didn't notice the issue until I flashed the AOSP rom. But I also flashed the Gingerbread rom where nothing really works that was in the dev section.

anyone else stuck on 1x?

im in NYC and i tried to flash a bamf.1.8 rom and was stuck on 1x after that. i thought it was the rom so i flashed cm7 rc06. again and 1x still. so is this a verizon issue?
Lots of us are going back and forth between 1x & 3g, and i'm in constant 4g area. Verizon must be working

Is your back cover on the phone? - It has the antenna and without it...it will not connect to 4G from my experience.
Then again, I'm in Bay area California and right now I have 1x since 12am. - I'm perplexed with the case because I didn't do anything since I just arrived back from Lake Tahoe about 4hrs ago.
*Possible that it's a Verizon outage issue. - Nice to see this since I just moved away from Sprint to grandfather this LTE unlimited data.. Never had one outage while with Sprint XD
Hope that they get it together!
I noticed it's been on 1X for awhile this evening as well. I attempted a battery and sim pull and let it sit for a bit but it was still on 1X when I put it all back and rebooted a few minutes later. If others in different areas of the country are experiencing the same then it's probably something on Verizon's end.
I think it's Verizon
I think it's Verizon. because I'm in San Diego and normally get 6 bars of 4G and not I'm getting 6 bars of 1X and 3 secs of 3G. I thought I had messed something up when i flashed the MR2.5 Radio then I went back to MR2 and same thing and then you guys have the same problem too. So I know I'm good now lol.
Running Gingeritits
im here in so cali and im getting 1x also and sometimes not even that. for a second i was abuot to curse my gingeriitis. how dare i even think such naughty thoughts. its all verizon. maybe they are getting some 4g towers near me.....ok probably not.
I had this happen to me this morning. I rebooted and my 3g came back. Not sure about 4g since I don't get a strong signal at work.

Jumping from 3g, 4g and 1x this morning in Atlanta, now its all 4g
I agree. Must be working on the network. Some days i get stuck on 1x and then it will go to 3G. I am on 4G right now without any issues. I just flashed GB with the newest radio leak and its smooth so far.
Yeah I was still stuck on it til this morning but I did a reboot and on 4G
Live in upstate NY... for the times that we even had data it was 1X and only 3G for like a second. it was killing me cause I rooted for the first time and I thought I killed my radio.. I could make calls but no data.
I figured by the way it would come and go that they were working. Same thing when EVDO came. They screw around at night all the time and then try to clean up their mess by the AM. You'd have no signal some signal.. and then holy **** moments where you would have like full signal in areas where you never get full signal... When they get to playin they go nuts.
everything gravey here in So Cal

Dropping to 1x?

So if you don't have a custom rom you will never know this but anyone ever see they phone on 1x instead of 3g?
Mine seems to do it randomly. I will have decent signal and be doing something on the net like IM or checking email and it will just drop to 1x and snail mode, after being idle for a few min will go back to 3g.
It doe snot always do this but seems to about once a day and has happened at home and work now so not just the tower.
Just in hopes I don't need to exchange my phone or something
Again only like once a day but I just dont understand it. I am on MeanRom right now and has happened on all versions since I started on 1.5 and doubt is his rom and just that his rom lets me see the 1x now is all.

Yes!
I recently installed that LiquidSmooth ROM and now I find my phone dropping into 1X on a daily basis.
I have to turn Mobile Network off and put it back on for it to go into 3G. Otherwise it remains stuck in 1X.
What gives?
In Cincinnati I seem to see more 1x then 3g last week or so
Yes!
Mine will cycle from 4g to 1x all the time.
I've never talked bad about an HTC product but this phone sucks!
This have been a problem since the day I pulled it out of the box.

The phone doesnt suck. The network sucks. Welcome to sprint. The networks undergoing huge changes to it.

This is not caused by the network, this is a phone or firmware issue.
I have my Evo 3d and it does not do this in same areas.
I agree the network is slow which they are working on but this 1x is the phone doing something.
I wonder if this is a result of the recent FW upgrade or not, though guess not being a previous user said from day one his did this (which not sure how he would know that for sure as people didn't know it always said 3g right away to know to modify the rom)
My rooted OG Evo used to do the same thing in the Tampa Bay area. I haven't rooted my LTE yet, but I would assume it will do it too once I root.
Ya this happens to be and the best way I can fix the problem for me is to turn airplane mode on and then turn it off and it will go back to 3g or LTE

I'm having the same issue. Airplane mode fixes it until I find another weak signal area and it returns to 1x. It will remain in 1x again until I cycle airplane mode again--even in strong signal 55dBm fast data areas.

[Q] My problem with LTE...

... after quickly ready through some of the threads here, there seems to be a problem with alot of EVOs not staying connected to LTE signal. In thier experiences thier phone will find the 4G signal then quickly drop back 3G or thier phone will not even connect to a 4G signal even though they are in a confirmed 4G area.
I never had this problem until recently. When 4G went unofficially live in Los Angeles my phone would switch seamless from 3g to 4g and back. It was just recently in the last week that my phone now will not connect to 4G unless I cycle through airplane mode. Once 'im on 4G my phones signal is rock solid and stays on 4G. When I'm out of a 4G area it drops back to 3G but will not swap back to 4G when I return to a 4G area.
It so weird that all of a sudden it started doing this. I notice that when this happens i'm at half (or less) charge. Maybe my phone is doing this to conserve battery.. i don't know. I can see if my phone did this from the get go but it's just weird that for two weeks it was fine and them all of a sudden the radios are not swapping correctly...
thoughts?
UPDATE : So i got off the phone with HTC and they said it is a tower/carrier problem. Is this possible?

Possible: Yes.
But no, its exclusive to the EVO LTE. You can inform them that the iPhone 5, SGS 3 & LG Viper (I wouldn't say all of them, but some of them, you're just trying to get a point across) phones in your area, stay connected, where as the EVO LTE (say your's & a few others) does, not.
^It doesn't have to be true, but the fact that it is a bug, is true & it needs to be addressed. If it were carrier based, Sprint's other LTE phones would be in the same boat.
Say your'e reporting it as a bug & could you submit a ticket or add to an exsisting one. (Heck, they might not even have trouble tickets.)
People mess up the bug process by going back and forth with the rep, just stick you your guns & stay polite.
I think it's an Evo LTE thing myself. I just got LTE here in LA, and I actually just noticed that I was back on 3G for whatever reason. Got back on by airplane mode-ing.
Although, I will say that it has gone to 4G automatically in another part of LA, so I'm not sure what's going on with that.
I would've liked for the LTE to be a toggle like 4G was on the OG Evo.
I wpuldnt know, Arizona never gets any love haha

I think it was the towers because all of a sudden my phone is switching seamlessly again.
