So... About 4 days ago, I noticed that I couldn't connect to 4G anymore, but 3G works fine. Now I've always had full signal 4G where I live because there's a tower just down the block by the Sprint store. I can connect and I even get an I.P. address, but there's no data getting through. You can imagine how many times I went to recovery, cleared data, wiped, re-flashed, all the while thinking it was the ROM that had problems.
The answer came to me in the form of my younger brother. He has the Evo Shift and also had been having issues with his 4G. Now his phone is stock, so that ruled out the ROM being the issue (thank GOD I thought I somehow screwed my WiMax). So he tells me there was a power outage about 4 days ago at around 3am, since then he hasn't been able to connect.
What I'm thinking is- IT'S BEEN 4 DAYS... You guys here who work at Sprint, do you think a small power outage can bork the 4G network for 4 days?
And if so, how come it hasn't affected the 3G network as well?
Maybe It's another issue altogether...
Sprint actually has 4G?

4G is WiMax and 3G is EVDO so one getting knocked out might not affect the other....also, if they haven't had reports about that particular tower, they might not know to fix it.
To the poster above: if your not going to be helpful, don't post.

That sucks man. I'm blanketed in supposedly 4g service and can't get it neither. I wanna go take a dump on one of their towers.
Can a power outage kill 4G? Certainly. Cell towers work like many other electronic devices, and are still prone to things getting shorted (Even if there are several layers of protection to try and stop that). I would honestly recommend calling tech about it and seeing if the towers near you have any posted outages, or at least report the issue.
They likely cannot fix the issue unless they know about it, and if everyone presumes everyone else will report the issue; it may never get reported.

I'll call tomorrow and bother someone over at the local sprint. I'm just wondering how did the 4G go out and not the 3G network. Oddly enough I also noticed the 3G network is slightly faster now... i.e. - I could never watch HD movies on Youtube without having the 4G on, now since of course I can't connect I tried on 3G and it didn't skip a beat. Maybe breathing too much spray paint fumes is making me crazy
The 4G sits on a separate tower from the Sprint tower's as the 4G is provided via Clear.

Today I lost all data. Sprint says it is because they are updating their towers. Should I have this problem all over Dallas? My wifes phone works fine. Spent an hour with tech no luck. I went to the Sprint store and they just said people have been coming in all day.
My two friends with the same phone have no issues and one other with a rooted phone has issues. I hope I didn't lose data because I rooted my phone.
Any one else having these issues?
You can be certain that it isn't the rooting itself that would cause your data issue. Try going into your settings>Mobile Network: and where it says "Network Mode" select it and choose "CDMA Only" and see if you can connect then. With network vision being so close I would image alot of strange things are going on in those areas (im in the atlanta market but havent experience and problems). And one guess I have is since data is fine on a non LTE-device, it's almost CERTAINLY a tower work kind of error. Our phones (lte phones) have different PRL's than non LTE phones so our phones choose what towers to connect to , and how to connect to them, differently. I'm sure this will be remedied extremely soon. probably fine by the time you wake up in the morning.
Im in Grapevine/colleyville and I frequently loose data for a sec, but not long periods of time. It's cause of the lte roll out. Should be all good on july 15th
Thanks guys, puts my mind at ease. Can't wait til it's here.
Live in Dallas work in grapevine, same issues. Hoping 15th roll out solves everything, luckily I'm on WiFi at home and work so its not overly unbearable. Grapevine however I have trouble with text sometimes.

Im actually having the same issue here in Houston. If network mode is set to LTE/CDMA, i get no data. Still shows 3G, but the arrows that show receive/transmit show the transmit arrow solid. Where if I change my network mode to CDMA only, data works fine.
So HOPEFULLY it is as suggested, tower work due to Network Vision. Fingers crossed!
Yeah I have the same problem . I loose data complety . Sprint said it should work. I don't know if its the phone prl or the towers . I also heard a few people say it was happening to people with rooted phones but I really don't know . I live in fort worth and loose data 20 plus times a day .

Same issue in Austin. The CS rep I'm talking to speculates it might be tied to the storms in the NE/midwest.
I'm also getting errors updating my PRL and profile.
On hold with tech support right now. Once I'm done, I'll try setting my network mode to CDMA only and see if that helps.
Well today i had no signal and everyone i know had no signal we all have sprint. Sprint said as we speak they were working on the vision project for the towers for lte and from what i read online today was they day they were working in my area. The plan for lte was to start with the small towns around Chicago and then chicago last so people in Chicago could pick up signals from near by areas until the towers in Chicago get updated. Theres more cell towers in chicago alone then the rest of illinois combined so this make perfect since. I'm from Rockford Illinois and i have horrible 3g speeds. Hoping they flip this lte switch soon.

Things are working for me again. Sprint tech guy had me dial ##72786# and input the password 033322. From their, he had me hit menu and reset.
The phone rebooted and reactivated. Then I updated my profile and prl. Those failed the first few times, but they worked when I set the network mode to cdma only. Switched back to cdma/lte and everything's back to normal.
The tech did confirm that we were feeling echoes of the network disruption (due to a storm) in the northeast.
I live in Richardson and work in Plano. No 3G issues anywhere for me. Including going into downtown Dallas yesterday and today.

I'm stunned at the constant complaints... I believe half of.. everyones issues are due to screwin around and f"n up their phones ,not reading stickies ,,rules , not.knowing...compatibility
The other half is probably defective devices NOT all of us have issues I've had none

Welcome to Sprint
I really haven't tinkered with much of anything on my phone and I find the most recent OTA to be MUCH MUCH buggier than the previous version. Before the update I never had Sense crash or any other programs crash. Now they happen once or twice a week (sometimes several in a day). Add that to the fact that I am not S-OFF and I have a loathing hatred for this most recent update.

If updating prl/profile doesnt work get your radio checked. If the radio is fine its sprints network

Sorry, but I'm not convinced that my text, roaming and dropped call issues are solely due to the upgrade. You guys can keep screaming that all you want. And I'm not saying that there aren't instances where that's the case. My wife has a shift and isn't experiencing these issues. I've also read about other evo owners with two phones or other sprint phones in their household -- none of which are displaying the same problems.
Again, I'm not saying the network upgrade isn't causing any issues, but it's a bit aggravating to see people post that in every thread containing an issue that can even remotely be attributed to the upgrade like it's gospel.

If you're complaining about SMS issues, missed calls, dropped calls, ect...
Go get your radio tested. It takes 30 minutes at a sprint store. You don't even have to unroot it. Hell, tell them its rooted so they don't mess with the software.
I may try bringing it in tomorrow.

Yep, pretty odd that my network problems started the same day I bought this phone. Op, Your is working great. Good for you but please don't treat the rest of us as retards.

For those not aware...the EVO LTe is set up out of the box to work on LTE and Enhanced CDMA (for lack of better term/knowledge) Also know as Network Vision, or the upgrades.
In cases where an older phone connects and the EVO LTE does, I have confirmed the EVO LTE is connecting to a network type called ehrpd. This network is not yet active in most cities. The older device confirmed to be connected to CDMA and receiving normal 3g.
This is the reasoning behind changing the network mode to cdma only, as many of us have seen that it forces the phone on to CDMA and not ehrpd.
I hhonestly have no idea what I am doing, but this is what I have found in my hours of testing side by side with older devices. From what I can tell every LTE device Sprint carries has this issue, but the other devices appear to lack the ability to switch.
There are also other issues that can contribute to texts and data.
This theory also works in reverse. If I am in an LTE area and on cdma only data and texts are wonky and I have to switch back.
Moral of the story...handoff could be seriously jacked up. I remember Verizon and ATT having similar issues during buildout. You would think someone had figured it out by now.

Dudes Sprint is upgrading 38000 towers its common sense that your going to have some connection issues and aside from that people living in high populated areas if one of the towers goes down for the upgrade the other ones are going to have way more traffic hence your problems......... I'm pretty sure that's right? And also if you if you can make calls and not receive calls or text but still have data your on data only o. O

A lot of the data/sms/call signal issues can be attributed to the current state of network upgrades, though it's obviously impossible to say 100%. In my experience, the network-related things have worked fine from day 1 (July 19th). That said, I have noticed actual system bugs. For example there was a time when I was using Talk (I hardly ever SMS anymore, Talk is way better IMO) and the text in the app became just a jumbled mess of pixels. Took a reboot to fix but it was still weird. And a friend of mine who got his Evo LTE a couple of weeks before me, his phone just started spontaneously overheating all of a sudden yesterday. We suspect a rogue app getting stuck in a loop, but still that's not a good sign; it should have been caught by the OS and at least thrown up a message to kill the offending application. Again, a reboot fixed it but I'm not really keen on that being an actual solution as opposed to a temporary workaround.

I've had my Evo LTE since launch, and have had call issues since the beginning. I came from the OG Evo, and knew Sprint had bad coverage in some areas around me; but this has been much much worse. I would say 4 out 5 calls drop immediately upon connection. I will have half or more signal when I call and as soon as it connects it drops off and I look and there are 0 bars. Oh, I'm also not in a town which has the updated network/LTE. I had done the HTC Unlock immediately, so I was nervous about trying to take my phone back. But thanks to this amazing guide, I can get it back to stock. Has anyone else had issues like this fixed by getting a new phone?
My main question is who do I take it back to? I have the BB Black Tie insurance, so I was thinking that would be easiest/quickest exchange. But I wasn't sure how they would react since there is nothing visibly wrong with the phone. And I'm sure as soon as I get in Best Buy it will work flawlessly .
are you in an area that is currently undergoing Network vision updates? In my area (Chicago suburbs), sprint acknowledged that the NV upgrades were causing problems.
I constantly get "no data connection" when I have 3 bars (not roaming) :/

Well, I think I'm going to go back full stock tomorrow and run it by a Sprint repair store. Guys in IRC channel recommended I have them check my radios. I work with a guy who has a Samsung on Sprint and doesn't have great signal, but better than mine! I'm so torn right now, I know if i switched to Verizon I'd have great LTE signal all over town, but I wanted to support Sprint and see if they could fix their network. Now I'm regretting it but stuck in contract. But then again if I were to switch, there aren't really any phones I'm interested in on Verizon...
I love this phone but, I am.pissed and tired of repair stores, and sprint technical, and supervisors, and credits. They can see that most of my disconnects are device related and still won't switch me to another device or something. I really don't even want to switch. But, I totally believe its network being upgraded and this device is designed for something other than what's offered in my area.

Send it in to htc and have them fix it. They warranty it for a year.
I had one that dropped calls but my second one is perfect.
Well, I'm going to try to get to the Sprint store later this afternoon. Will update here with result. If it's just their **** network, think they might let me out of contract if I ***** enough? If they do, then where do I go? I freaking love this phone, but if it can't make phone calls I can't keep it...
--Update--
I went to a Sprint store on Saturday to see what they said. As soon as I mentioned dropped calls and crappy speeds he started apologizing. Evidently they have begun the network update in Oklahoma, which means that a lot of towers are down or not at normal capacity. He said this has been going on most of the year and that the network should be back at normal capacity by the end of the year. He also said he had heard LTE by June-July of 2013, but was just a rumor. He reset my profile and PRL and said it might help. I'm going to stick it out as of now and hope they can produce a solid LTE network. I do really love Sprint and their fight for unlimited data, just hope they keep it up.
Dropped Calls
I, too, have had terrible luck with calls dropping with this phone. I was on the OG EVO and did not have these issues at all. From looking at this site s4gru.com I do not believe that my area (Indy) should be under any network updating as of yet. However, it also looks like Oklahoma should not be, either - so maybe they started early
In the end...my old EVO did not have issues up to the day I upgraded, and the new EVO has had issues since day 1. I do not believe this is a network issue, but more of a hardware/radio/phone design issue. I hoped the newest updates (including radio) would help, but I am still dropping calls way too often.
... 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.
