    Default No 3g or 4g all day. Just about had it with the Thunderbolt

    Any ideas whats up with this? I am just about ready to trash this phone and go back to the (reliable everything works) Incredible. I tried many restarts also. Any help would be apprecitated. BTW that was the guy right next to me has the incredible and had a strong 3g signal all day. He was laughing at me and said hows the Thunderjunk doing and signal yet....

    oy. yeah that would make me a little angry.
    question: have you tried the Phone Info trick/hack?

    download Phone Info from the market to do this easier than the Dialer Code
    open the app, and then go into Phone Information--then scroll down to the 1st drop down menu (it'll say CDMA + LTE/EVDO AUTO)--
    tap the menu--switch it to CDMA auto (PRL)
    this turns the phone to receive 3G signal only.
    instsantly, you should see the top of the screen @ the notification bar change and a few seconds later a 3g icon appear

    reason i'm saying this--
    i had it on CDMA + LTE EvDo auto since i bought it--but would suffer when not around a 4g signal, wouldn't ever even pick up 1x. so i switched it to CDMA auto (PRL) and now i get 3G signal everywhere that i couldn't get 4g signal.

    give that a whirl---if you already have, then forget i said it

    granted--this doesn't fix the reason why you're not getting signal everywhere,
    but like me,
    you couldn't get 4g or 3g signal. so, i told the phone to search for 3g signal only--and voila, it worked. i picked up 3g in the same exact spot that 2 minutes earlier received none.

    edit: updated to include Phone Info market link

    no problem.
    for some reason--when left on "cdma + LTE EvDo auto"--the phone won't allow the 3g radio to really receive any signal, it'll only get 1x & 4g. so, this kind of circumvents that issue.
    also, i edited the post to include the Phone Info app link

    hope it works!

    I had similar issues. Turned out to be a defective phone. Second one is fine. I do keep it in 3G mode as explained above since I am not in a 4G area. Thoughts are that this increases battery life and makes the 3G connection more solid.

    yeah--good point AubreyPage.

    O/P, you may want to go to an area VZW corporate store & ask to see a Thunderbolt

    if the display TB has 4g signal, and you do not--then the phone itself is probably defective and you need to swap it.

    Yea I just wanna add that it may be a tower signal issue. The other day when I first discovered 4G here I was trying it out and couldn't get 3G or 4G signal at work and was getting a little mad so I switch off the 4G since we just got it here in Columbia. My connection was back to normal. However today I had strong 4G signal every where and no issues at all.

    I had this same issue today. No 3g signal since about 1PM. I have mine set the 3g already. Reboot and pulled the battery. Then it just came back after awhile. Possibly VZW doing some maint in the area?

    This happens to me too - ALL THE ******* TIME.

    If I leave it as 4G as it should be, it'll drop out of 4g and go to.... nothing. Sometimes it'll then pop up as 1X, then 3G, then nothing, then 4g then whatever. Navigation is unusable. Pandora too.

    Unless I turn off the 4G back to Auto PRL with Phone Info, it NEVER WORKS dropping into 3G.

    This is bull****. I will NEVER be an early adopter again.

    As much as I HATED AT&T's data network here in Denver (slow as hell), at least the damn iPhone worked.

    I realized the other day i have massive 4g connection issues at school. if it cant find 4g, it keeps bouncing all over the place, in the process draining the battery in a couple of hours. luckily i turn off the 4g when I'm there, and i realized the other day my battery is totally killer while only on 3g. in any case i can totally live with this fix for now. do hope they fix it though. lol

    Sorry. Just ticked that I took an ETF to move to VZW expecting and buying into the VZW is better and they test the hell out of their stuff and it just works.

    Default Try this...

    I believe your issue is with the eHRPD 3G connection. I had problems when I first got the phone.

    dial ##778#
    select 'edit mode'
    password 000000
    scroll down to 'modem settings'
    select 'Rev. A' and change it from 'eHRPD' to 'Enable'

    That will put it on the normal 3G service.

    The eHRPD setting is new and is used for simultaneous talk and data. It was broken when I first got the phone. I actually switched it back to eHRPD a few days ago and haven't had issues. It could be fixed just in Southern CA.

    I had the same issue with my Thunderbolt. I had it for a week and when I was at work it would constantly go from displaying a perfect 3G signal (-65 dbm) in my office to displaying absolutely no coverage whatsoever (>-120 dbm). I called Verizon and they told me that I was in a known "low coverage" area. I knew this was not true because my co-workers that had other Verizon 3G phones had near perfect signal strength. I was also told that the Thunderbolt is "a 4G phone that happens to do 3G." What this means is it will look for a 4G signal first and if it cannot find one, it will dial down to 3G but since it is always looking for a 4G signal, it might have that behavior. They also said that they might be testing 4G in my area (Raleigh, NC) and that might have something to do with the problem.

    Eventually I got fed up with the issue and decided to get a Droid X on a 1 year contract to give Verizon/HTC to work out the bugs with the Thunderbolt. In 1 year hopefully LTE will be more mature with better devices on the market to support it.

    I should have said I have done that too. If, in my case, if I leave it in 3G eHPRD, and just turn off the 4G, it STILL screws up. Just not as often.

    I have to turn off the 4G with Phone Info and the eHRPD with ##778#.

    So basically, to make the latest and greatest phone even work reliably, I have to neuter the two features that are supposed to stand out.

    I had to switch to 3G this past weekend. 4G was nowhere on my phone. I usually get strong at home. Never had to used to LTE switch app til the weekend. Love the phone. Hoping that upcoming update will cure it all

    I haven't as I don't want to risk a unapproved update. It could be the phone itself is fine but Denver's just messed up.

    I can tell you that it isn't just Denver. I'm in TN and returned my phone because of this. I'm watching closely so that when it is fixed, I can go get a new phone!

    I think you are all overreacting and not noticing a trend here. For starters the majority of you are complaining that this issue has started, not had it since the purchase, although some of you have stated other wise. Personally I had this start happening to me this morning and throughout the day, annoying, for sure, the end of the world, no way. With all the testing they have been doing lately and with the launch of 4g in about 10 cities tomorrow, I am not surprised they are having some network issues. These things have to be worked out, just relax.

    As for the phones inability to switch from 4G to 3G properly, this will be addressed, and well if has been addressed in the leaked update which I have since flashed. Also we can all hope that in a future update VZW gives its users the ability to turn off 4G in the normal settings menu. All phones launch with issues, name a phone that worked perfectly at launch. Especially a first of its kind phone. If after an update or two things aren't working correctly, then sure by all means, complain away. But you all knew what you were getting into when you decided to get this phone.

    Well, should have known. I agree.

    Funny thing is, if you just turn off 4G that's usually all it takes for virtually 100 percent reliable network performance. There are those who will say, why have a 4G phone that won't do 4G... well, no other phone on VZW will do 4G either. So...? What phone are you gonna get? That, and then there's the fact that we now have demonstrable evidence that a new OTA firmware fix is on the way to address this issue. Considering everything, AFAIC, I still have the best phone available on VZW right now.

    I think this is a great attitude to have. I am in NH and I've had some signal issues, but it's true. We knew what we were getting into. And for some of us who may be getting 4G soon, one day or two's signal struggles may be worth it. Keep in mind that Verizon's got to test things somehow. If you're having signal issues, give them a call. Just maybe they can help.

    I really don't get this because I had connection issues when I got my T-Bolt so I called and emailed VZW and HTC. VZW was no help really they just said we know thanks we'll get back to you. HTC on the other hand said this.

    HTC
    "With regards to network hopping - basically the device flips between no data connectivity and 4g/3g. We have been escalating these cases as needed for further analysis as well. In almost all cases, the carrier, being Verizon, has been able to reprovision the SIM card which should fix the issue. If your issue is not fixed by this method, we would like to have your issue escalated, and we would be happy to contact you by phone to perform all the necessary steps and then escalate the issue as required. We do have some examples of this issue at our escalations desk currently, and are working with the developers to narrow down the cause and find a solution as quickly as possible."


    I don't mess around with the " Set preferred network type: " and my T-Bolt works amazing. When I read all these posts and all I see are " turn off 4g " and " dial *#*#4636#*#* then change settings to ... " I scratch my head and say to myself " have any of these people even talked to the manufacturer about this?". Please for my sanity try calling VZW at 1-866-221-4096 option 3 ask the tech to " reprovision the sim card ". They will have you power down the device > pull out the battery and sim card tray > wait > then reinstall and reboot.

    Default Signal Issues

    I had a thunderbolt for three days and hated it, there is a fix for this issue though. The thunderbolt has a power management app that is cooked into htcsense on the phone. What you need to do is go into menu, settings, and find wherever it is, and turn it off. For some reason, it disables your 4g/other data connections because they're draining battery. It does this especially with 4g, even if you're in an area with a very strong signal. Hope this helps! It worked for me when I had the phone...
