mobile data dropping? - Sprint HTC EVO 4G LTE

hey is anybody experiencing mobile data disconnected most of the time,
im on meanbean rom, and i been experiencing this ever since i got the phone is pretty annoying because i use the network alot, i have to turn it off/on if that dont work, i also try airplane on/off but i have to do that most of the time. We have no 4glte in CT still but i have not experience this with my other evos
is there away to fix this, so it could be more stable i dont think the problem is with sprint, i think is my phone,
a have also flash the night mode zip, update my prl and profile seem to help but not for long
any help thanks

This is an issue with every lte phone and it has to do with your network mode. If you don't have lte in your area switch your network mode from cdma/lte to cdma only. You should keep a steady 3g connection after that.

yeap. most networks are now on eHRDP or whatever its called and sometimes when it loses connection it takes a while to re-establish no idea why. for simplicity sake just turn your LTE off and move to CDMA (auto PRL) for now. then you wont get any drops.

I have LTE coverage and this happens to me at least once a day. If I leave my phone off for a little while and come back to it the 4G symbol will be there but it will be grayed out and will not upload or download and eventually it will say disconnected. The only way to fix it I can tell is to cycle Airplane mode which sucks but it is what is it. Glad to see its everyone's problem not just mine.

WiFi Problem?

So I just picked up a Thunderbolt from a local Verizon corporate store. The sales rep told me NOT to use WiFi on my phone because of an issue all Thunderbolts are having. She said once connected to WiFi, it won't be able to switch back to 3G unless you perform a factory reset. It sounds like a load of crappy to me, but I'd rather play it safe. Can anyone confirm or deny this out there? Thanks in advance!

I think I've read about a few people having that issue, but simply switching airplane mode on and off fixes it, I believe.
Pretty sure that rep didn't know what the hell she was talking about. I think it's a safe bet these and other boards would be blowing up if there was a problem as massive as that affecting ALL Thunderbolts.
And my wifi is fine!
yea mine doesnt want to switch back to 3g but a simple restart does the trick, and some vzw reps are idiots deff no factory reset
I use wifi all the time, no problems here.
I use WiFi at home and 3G when i'm at work, i have no problem switching between the two, the sales rep that you were talking to doesn't know what he was talking about

Same here no problems switching from wifi to 3G or to 4G
I've heard people complain about this, but the solution for now seems to be turning airplane mode on and back off. From what I've seen it's not a super common problem, I've never had an issue.
Yup, no problems here.

Sometimes my wifi stops working even when its been on all day. It shows its connected and I have a strong signal, but when I try to use an app that needs a connection the app wont connect. The only thing that fixes it is turning wifi off and back on again. On top of that I noticed huge drains on my battery when this happens.

same thing happens to me. then if I turn off my Wi-Fi sometimes to try and get a 3g connection it takes like 10-15 tries to get a data connection. And even sometimes when that happens I'll turn my Wi-Fi back on and my Wi-Fi acts buggy, doesn't connect... I'll have to try the airplane mode trick
I have the same problem. Changing the EPST setting as found from an Engadget Post:
HTC Thunderbolt 3G data problems solved?
By Myriam Joire posted Mar 30th 2011 7:43AM
Sort of fixed the problem. However, I rooted to Tesla Coil and now cannot use the "##778#" easter egg dialer anymore.
Just tried the Airplane mode and phone rebooted, doh. Again, after starting up WiFi, no 3G coverage.

No problems here. I use wifi 90% of the day. Although, strangly my router now shuts off its wifi signal ever since I bought this phone. I have to go into my router and setup the network again.

Cannot grab any 3g/4g data connection.

Ever since around 6pm pst my tb has bars but will not show a 3g/4g connection. I can recieve calls but cannot do anything datawise. I'm typing this over my wifi as a result. I've tried a reboot with no success. Any ideas? I'm running BAMF 1.7 Remix. If anyone in the SF area has similar problems (I'm in Berkeley) I'd like to know.
Thank you.

Do you have any kind of battery saving app or something that turns off data while your phone isnt in use? It might have glitched and isnt turning it back on. ( i know this happens sometimes when i use JuiceDefender)
i can't say about the SF area, but in Denver there has been inconsistent coverage the past week. Reading in other forums seems that VZW has had some spotty service just recently.
Is your back cover snapped on nicely?
Edit: And every once in awhile, 3G/4G will be down in certain areas. You could also try to switch between CMDA mode and LTE mode, that actually got my phone out of 1X several times.

[Q] 4G drops to 1X

I recently upgraded from the Incredible to the Rezound and find that when 4G not available, the signal drops down to 1X. Not only that, it seems to stay in 1X even when 4G is available. How can I get the phone to drop to 3G when 4G not available? The Incredible ran in 3G in the same areas that the Rezound drops to 1X. What do I have to set to get it into 3G?
Thanks for help.
both my GF and I have been having trouble with this on both our phones... We both live and work in 4G coverage, pretty strong coverage too. Yet we both see 4g drop out to 3g or 1x. Its very random, and I've had it happen right in the middle of browsing the web. (All of a sudden a page takes forever to load or doesnt and the phone acts like it has no data connection, I go to the home screen and see that I am all of a sudden on 1x..)
I recently read an article that talked about how VZW actually has a pretty major issue they need to resolve pertaining to authentication on the LTE network. I don't know the exact mechanics of it, but basically the authentication fails and you get booted off the LTE network until the phone tries to hop on it again. Right now, the two phones I have personal experiance with do not try very often to get back on and it often takes going into the wireless settings page and selecting mobile networks and going in and out of that screen a couple times, or if it is being stubborn, airplane mode, site for a minute, and then back on. Occasionally I have to reboot the phone.
It really irritated me good last night when I really needed the data connection for GPS navigation because I took a wrong turn in an unfamiliar area..
Sometimes going in and out of airplane mode helps or restart.
I'm not going to say look on the forums. Here is a quote from another thread and linked another thread.
had the same issue and fixed by this.

phone will reboot and you should get 3G back
This changes your network from eHRPD back to EVDO Rev.A. For LTE phone owners, eHRPD causes 3G to die (most of the time anyway) when the LTE network has problems. Get back on normal EVDO and you're good to go.
^ from Jntdroid on another forum (not sure if we're allowed to post to other forums here) I'm not positive on where he got it from, but this is a capability of all HTC 4G phones
I've had occasional issues with being down to 1X, but even that was only during nationwide 4G network issues, definitely get in touch with VZW about that... not that they have enough sense to fix anything *sigh*

Same issue here. Only happens when I go from a 4G area to a 3G area. I end up getting stuck in 1x. The phone switches fine from 3G to 4G. But when going back to a 3G only area, it by-passes 3G and I get 1x.
No toggling helps. I have to reboot to get 3G back. I also tried that fix posted above. It does not help. Called verizon again tonight.
The strange part is before we had that 4G outage a few months ago, the phone would switch just fine. Now it's a pain in the ass.
Sorry it isn't helping. It worked in mine and done exactly the way it told me. Go from 3-4g now without an issue. No 1x like before

Data Call Failure

Is anyone else having an issue connecting to 3G. I have to disable LTE and then reboot my phone to get 3G to work. Every time. This also causes an issue when trying to update PRL/Profile. It fails 4/5 times with an error code before it actually works.
Also, the wireless tether connects via 3G but hangs over LTE.
Any insight would be great.

Oh and just some more info. My LTE works great. Hasn't dropped once yet. Fast too

Yup i am noticing a huge problem with my device NOT connecting to 4G (i am in Dallas) and i AM noticing my device saying 3G but the TRUTH is its stuck on 1x. I have Mobile Signal Widget Pro and it will show 1x or an exclamation point instead of H or EVDO data. When the device gets stuck like this its a battery killer.
I too have to shut it off and turn it back on.
I also found that sometimes i have to switch my connection to CDMA only and not LTE/CDMA.
I had that issue the other night... Went away immediately when I paid my bill though... Go figure, lol.

I was having a similar issue, and I was getting an error code 1012 when trying to update profile. If it persists either call Sprint or try a data reset.

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.
