[Q] 3g and 4g gone, only 1x - Thunderbolt Q&A, Help & Troubleshooting

I havent done anything to my phone lately and besides just having roms on it...so i my 3g and 4g data is now gone and i get 1x signal. The signal alternates from 1x to no signal at all. This http://forum.xda-developers.com/showthread.php?t=1457659 is what i got on my phone right now and i got the radios installed and i still get 1x. At one point 3g showed up, but its really slow. So my question is, how can i fix this network problem?
ps. i have been struggling with this for 2 weeks and ive decided to try and fix it, but no luck
edit: ive taken the battery out and luck either, i also found a thread on how to fix the problem but it didnt help

i too have had this problem for 5 days now. i have been thinking of flashing the phone again to see if it would fix it.

Well i got some signal now, i went ahead and just added another ROM. I get signal every now and then, but i think i would have been better off with just constant 1x signal, instead of having no signal at all then some 3g coverage (really slow for some reason).

I just rooted my girlfriend's Thunderbolt last night and I'm having this same issue.
I had to roll back her latest OTA update and go back to 2.11.605.0 and then run Revolutionary. Since I rolled back her software, though, I've had the 1x signal issue. I assumed that installing the new ROM would fix this (BAMF Forever 1.10).
I've installed BAMF after using Superwipe, and everything runs smoothly. It's a great ROM. However, I can't get anything above 1x signal.
I've done the trick using ##778 and changing the Rev. A setting...no dice (and from what I've read, this is better in areas with no 4G. I live in Brooklyn, so I definitely want the 4G LTE).
I've tried the MR4 radio released just a few days ago, the radio from 2.11.605.9 OTA, and the MR3 radio. Same problem. I guess I'm going to try out the remaining radios I haven't touched, but I honestly don't think that will do anything.
Does anyone have any suggestions??

Ok I take this all back, she tells me her phone now reads 4g lte with full service. Looks like jumping across a few cell towers did the trick.

have you tried using different radios? This solved my issue. I had to go though 3 radios to find the right one, but it worked.

[Q] 3G acting strange..

So all of a sudden my TB's 3G started acting odd. It disappears (the 3G icon disappears) unless I'm checking for updates, in which case it randomly reappears and seems to be doing work. Toggling airplane mode on and off doesn't help nor does turning the phone on and off. I can still get texts and calls but no 3G...
Tried everything (going back to ROMs that were backed up from a few days ago) as well as flashing that full new ROM/radio update. Wasn't doing anything specific before it went out...
Any ideas?

I didn't find that this worked at all. Only since the new radio was installed have I found 3g drop because I know I am in a partial 4g area. So for the time being I don't want to turn of the ePHRD. Has anyone else experienced this since upgrading radio and such?

Well I did upgrade the radio and this fixed the problems I was having. Getting great speeds now. But I'm far away from any 4G areas :/
I am having all kinds of problems today with the 3g icon going on and off. Sometimes when its on I still do not have data connectivity. Is this a verizon problem or just the new radio?
I think it has to do with LTE being prepped to roll out and more intensive stress-tests that they may be planning.
I've been having similar issues. I did the entire rooting process then flashed BAMF 1.5 and had little radio issues, but once I saw the 3G cut out a couple times yesterday, I flashed the radio that was already on my SD card. Since then it randomly cuts in and out, and sometimes requires a full phone reboot to come back. I don't think it's Verizon at all (at least not in my case), although my area is supposed to get 4G sometime this year.
I'm hoping the official OTA has a "better" radio that can fix these issues...since I sort of had issues like this in Boston when I was stock, but at home out in Central MA, 3G was as solid as ever.
Just an update in case anyone was reading this older thread--I continued to have signal issues for a day or two after rooting but I think I just had bad timing on flashing the new radio. I've spoken to a few Verizon customers (my mom included) and many of them had 3G issues the last couple days. Yesterday it was solid as a rock, signal better than I'm used to. So it probably was just a Verizon outage, testing 4G or whatever it was that they've been doing.
It's Verizon outages right now, lots of testing upgrading going on with VZW right now.

4G outage in LA?

Hi guys, I recently flashed BAMF1.8 and MR2. It was working pretty well yesterday, but today I have no 4G at all and 3G seems to drop in and out at random. Sometimes, I don't even have 1x. Does anyone else have this problem? Is it a network issue or did I royally screw something up? Thanks!
im having the same problem i was using bamf sense 3.0 RC4 for a few days nd my mobile just stopped working. two days of flashing roms and radios i still got nothing verizon gave me a new sim nd still nothing i havent tried going back to stock, is that what i should do nd try to get a new phone? after trying to activate my phone online i have 1x now but i did have a few minutes of 3g/4g then nothing again HELP PLEASE!!!
I saw this same exact issue on Das BAMF Gingerstripped and it was really freaking annoying. The fastest solution was a reboot, but it was possible to wait it out until data comes back.
Another thing I started to play with before I flashed to CM7 was using Plane mode as a way to re-engage Mobile Networks (3G + 4G) to get data back. It worked sometimes, but other times nothing. So far running about 24 hours on CM7 and have not had this issue yet, where as on Gingerstripped BAMF I was seeing this problem daily.
I also just flashed the newest radio (1.70) and will see how that works. I'm hoping I just don't see this issue again at all, don't care if its due to CM7 or the radio. I just don't want to deal with it anymore.
Going to airplane mode and back didn't do anything. I guess its a problem with my phone then.
After disabling LTE completely, my phone works perfectly on 3G. Does anyone else in LA have 4G issues? I've flashed a bunch of roms and radios to no avail. I just want to know if I should keep tinkering or sleep on it. Thanks!

try going to a verizon store and see if their 4G devices work properly. at least that'll let you know if the network has issues.
ZIP = 90024
I've had no problems with 4g in northwest LA today. I'm Vanilla Bean's latest release on a froyo radio (can't remember which one, but it isn't the one that was leaked today)
I'm in ZIP 90007 and what's been happening is my phone seems to be connecting to 4G, but it doesn't work and just sits there. =\
It was stolen by Mexicans.

oh yeah...i'm running bamfsense3.0 rc4 with the latest radio.

[Q] 4G issues on rooted phone.

My 4g is not coming on a "fringe" areas anymore, and when I am in the heart of a 4g market, it cuts in and out. It will show 4g on the notification bar, but will not connect to the internet, or will just show an upload arrow. It will eventually work if left along for a few mins, but then cut out or freeze again.
I've been rooted since July, and this is the first time i've had these kinds of problems.
I'm currently running BAMF Forever 1.0.5. I don't believe it to be a ROM issue, b/c i have since flashed other ROMS just to test, and still have the same connection problems.
I have pulled the Battery and sim, and made sure the battery door was on properly. I have tried every GB radio out there, and have not been able to fix it.
My big question: Is this a hardware problem, or could it be a bad sim, or something else?
Since my phone is rooted, how exactly would i go about discussing my 4G issues with Verizon? Would it just be best to nandroid my ROM, and install a rooted version of stock? Can i call and ask for a new SIM over the phone, or will i have to go into a store?
My phone is still usable, as the 3G works fine, but I would like to try and figure out a way to get 4G operational again.
If you've read this far, Thanks.

did you go from rooted stock rom to the Das Bamf Forever gb rom without flashing a new radio? there are links in the development forum to the new 802 radios that i would recommend. i'm using that with shiftao5p and 4g is running great.
I am having issues with 4g in my area too. It was just turned on in my area a couple days ago, but I live in the heart of the area and get nothing but 3g. In certain areas while I'm driving I've noticed that it will connect to 4g, but not for long and when i have been able to do a speed test it has only been around 5 meg down which doesn't sound right.
I'm using the latest gingeritis 3d and have tried all sorts of different radios. I've pulled the battery and the sim card and no dice.
Does it just take a little time for them to get everything working and then the coverage will be what its supposed to be?

Lost 3g but 4g and 1x work.

How do I fix it? It was working fine a week ago, I'm running eternity, 1x is too slow, i thought it was just displaying wrong icon but it is not. I've updated profile, tried different PRLs even 00001 and still no luck. 4g works great.

I have this issue for a while now just figured out my 3g has not been working for a while. Any answers to this?
I'm am not sure on whether either of you guys are cdma or gsm but it sounds like you guys flashed a outdated prl. you could try flashing a latest prl or perform a prl update to see if that works. Also, another problem could be you have older firmware that isnt playing very nicely with prl's. Upgrading your radios might solve your problems. Again, hardly any imformation on your ends have justified the current attempts at formulating an adequate solution. Usually these methods will cure you of that dreaded 1x signal.
If you're on a stock sense ROM with working epst. Do ##data#, enter your msl, then hit menu and select restore profile. I did this when stuck on 1x. You'll go through a hands on activation and should have 3g back again.

Borked 1x antenna?

Recently I have been experiencing, like many others, difficulty maintaining my 3g connection. It drops out at random times, sometimes staying off for 18 hours at a time regardless of reboots, flashing different roms, resetting my phones profile or reactivating my handset.
One thing I have noticed though, is the fact that my phone never goes to 1x. Ever. It's either 3g or nothing.
Do my questions. Is there a way to test the function of my 1x antenna if it is indeed separate from the 3g antenna?
If they are not separate, is there a way to reset it in some way?
I am currently running the latest radios from The good Capt. Throwback, my thought was to downgrade them and see if functionality returns.
Any ideas on how to proceed after that would be appreciated.
Mr. B.
ETA: running Jamie's latest PAC and have run PAC and RootBox almost exclusively. Stock kernel. No tweaks. Flashed latest radios about 30 days ago.

Jeezz...I had almost the exact same thing happen to me the other night...I had chalked it up to messing with a torrent app...but out of no where I lost my 3g connection, and it went to 1x...and the 1x would also cut out leaving me with nothing at all every 5 mins or so(the weird thing tho, is when the 1x connection would disappear I would lose the 3g symbol but in the network type it would list EvDo now...but I would not have any connection).
Naturally I was crappin my pants lol, I can't use the update profile feature on my phone, it's on Boost. So I went ahead and flashed the phone over again...Still the problem was there....So I did a factory data reset....still the problem was there....finally I went ahead and did the ##786# factory reset, flashed the phone again...Finally I was back on evdo like normal.
(BTW, my Evo LTE is now running 4.0.4 stock and there happened to be two of my friends here with their flashed to Boost Evo's, which were all running on EvDo with no issues...Plus I fired up my OG Evo 4g that is also on my Boost account and it was running on EvDo no problem whatsoever....so I knew this was some crazy issue with my Evo LTE)
I'm just glad the hard reset fixed it, I've been paranoid ever since though checking my network status, making sure I'm on EvDo lol.
Thanks for the responses. I've tried every reset I can find. Flashing the older radios didn't help either.
At this point, I'm just trying to figure out if the 1x radio is functioning. At least I wouldn't completely lose my data connection when the 3g drops out.
This happened to me when they were doing tower work in my area. Lasted a few days then I had 4g in areas I never did before.

I can only hope that's the case, Thick. It would be the best possible outcome.
By the way, thanks for the kernelly goodness.
It's the most likely cause, sprint has really been stepping up the rollout, in less than 2 months my lte coverage has practically tripled
could be eHRPD switching, I know deck got it all fixed up in the cm10 nightlies.....are you in a LTE area?
if not try setting mobile data to just CDMA and see if it sticks. I had that issue on the early cm10 builds where it would try and switch and just drop data completely.

My area in Jersey is on the short list for LTE activation in the short term, so there's a really good chance of this being the case.

My confusion comes from not having 1x coverage where I used to have it. Is that coverage dropped once LTE is activated? That would explain my issue.
I have read up on the eHRPD handoffs being an issue, but since I don't have LTE coverage at the moment I ignored that as a cause. I'll check out the newest Deck build and see if that helps anything.
Thanks for the help.
