I spontaneously lose all reception - switching flight mode on/off fixes this - Vibrant General

This happens many many times per day. many times per hour even. my Vibrant keeps losing reception spontaneously. however the following always fixes it and gives me full reception again: switching flight mode on and then off.
my carrier is Wind Mobile in Canada. they're new and are known to have call quality issues. I'm wondering is the problem simply my carrier experiencing over-capacity or is there something wrong with my phone?

I was having an issue similar to this on T-Mobile in Florida. I would still have data but would lose text and voice. I asked about it in the TW chat room and Stumpy suggested a Odin back to JFD and check the Clear EFS Phone box, this seems to have fixed my problem as I have not had the problem again since doing this. Perhaps you could try that and see if it helps. I flashed via Odin to JFD and checked the Clear EFS Phone box, then used Kies to upgrade to KA6. So far that problem has not occurred again.,

Which rom are you guys using? This happens to me a lot too. I mean I can pinpoint when it happens too. It only seems to happen when I have the phone in 3G only, but if I enable 2G and 3G swapping then it's fine. The radio seems to have a problem re-establishing a 3G signal which means that everyday on the way to work and the way home when I pass Anaheim I need to reboot. Annoying.
I'm using Bionix-V currently.

Currently, my phone has been updated from JI6 to KA6 (Froyo) using Kies Mini, then rooted using SuperOneClick, then flashed to KA7 Voodoo Kernal using Odin.
Should I take any steps before flashing back to JFD? or do I simply begin by following the instructions here.
EDIT: got the upgrade/flash steps wrong

happens to me too. have to reconnect just to have data.

Just don't forget to disable Voodoo first. Make a file called disable-lagfix in the /voodoo/ folder of your internal sd card. Then reboot and your filesystem will be converted back to the scrap samsung uses.

This happens to me only when near a particular cell tower. I'll be right next to the tower and its been like this for the past two years, regardless of phone. I guess their network switch or whatever they use in those things is flaky.
The tower next to my house has not once yet had a connection problem.

UPDATE: got a new SIM card. everything is perfect.

i am having same problem, i tried new modem and new rom but phone still keep switching to flight mode and cause me to lose all signal. i guess I will get new sim card as well. thank you!

Getting a new sim card sometimes solves the issue, but other times, trying different modems is helpful. Ive been on KB5, KA7, JL4, and currently on KB1.
KA7 had consitent signal, but text messages took a long time to send through.
JL4 barely gave me signal. and KB5 was laggy. Well see how KB1 works.

What rom are you running? This used to happen all the time when I used D9

Incredible doesn't detect 3G

Hey all,
I got the July 27 leaked Froyo and went ahead and rooted to 2.2.
I have noticed a pretty serious buggy issue regarding the phone not detecting a 3G network so when I'm away from my wireless router, it only shows bars, no 1X or 3G.
I have two options at this point, one of which has done me no good. Perhaps someone can help me.
Option 1: Downgrade back to Android 2.1. (More on this later)
Option 2: Try and find a way to keep this version and get back on 3G.
Lemme explain: I tried placing the PB31IMG.zip on the SD card and going through recovery to return the phone to stock. Each time I attempted this, it told me the version was old and it failed. Is there a workaround on this or do I need to find a different stock ROM?
I used unrEVOked to root the phone and have not been trying to do any frivolous additions or subtractions. I just wanna be back on my 3G. Any and all help would be HIGHLY appreciated.
Thanks!
Did you try *228 and update your PRL?
Yes. It did not help.
Always have 3G coverage where I'm at too. So more than likely phone is issue unless a tower around here is down (which I highly doubt).
Toggle Airplane Mode on, then off.
JC
Sadly, toggling airplane mode has done nothing to help either.
Upgrade to the 8/1 version...see if that helps.
JC
Try shutting the phone off, then powering back on. Or possibly that combined with an airplane mode toggle. Also make sure your mobile network is on in the settings for wireless networks. This problem was common with the first leak. I have not had it happen since switching to the second leak of 2.2.
Considering the missing apps and media in the 8/1 Leak would it be ok to do Sky Raider or should I just try the 8/1 Leak done by aiccucs?

I believe mrozzeh also gave a link to the full version of the 8/1 leak, if you are concerned about missing apps/media...
Doing that update has not helped me.
I guess I'll have to go down to 2.1 again. However, as I said, it won't load the PB31IMG.zip. It says the file is old. Any ideas?
Stupid question....you did upgrade the radio right?
Yes. Radio is the 2.x baseband.
I would be VERY finicky to update that again as I do NOT want to brick my phone.
Ok, it seems I have found a bit of the issue that is causing it. My phone number and IMSI are not detected as my current phone number. Is there a way to program this or is it an issue where I'll have to have it reprogrammed by the local Verizon rep?

try a *228 and option 1 so the phone is reprogrammed. then do a test call to your vm(*86) and make sure it connects, you should not see the 3G symbol, when you end the call, the 3G should be displayed...give it a whirl
This did not work. There has to be a way to program the phone number into the phone. Any ideas?
i've been having this same issue... messing with airplane mode and rebooting a few times got it to fix... *228 and option 2 worked sometimes. just loaded up Adryns new evo hybrid rom, working fine so far (the problem was rare, maybe twice a day tops) and did *228 1, we shall see!
To no avail on these. I think I'm going to have to see a rep tomorrow and see if we can get the phone number (my actual phone number) programmed back into the phone. I think that's a VZW thing as I'm sure they won't run me through the methods to program a phone number.
I hate that I have to go back to Big Red over this, but it is important for me to have this phone up and running. Besides internet, I have NO other form of contact.
3g issue
I had the same problem and so have many others, I flashed Skyraider Rom and problem is gone so we know its not a buggy radio, I don't think there is a fix right now, but I've never seen a Rom so stable as the new Skyraider, so you might wanna think about flashing that Rom.
Coincidence. I've heard the same with my roms, from both ends of the spectrum. Its for sure a buggy radio, and how it interacts with Froyo. Once we get a 100% Froyo ready radio, I doubt we will ever hear about the issue again.
This is the first I've heard of someone not being able to get the 3G connection back at all. Is that what you are describing? I had it not turn on, then come back after a *228/2 or power cycle - but it always came back on. Just curious but are you on an Alltel plan by chance?
Can you make calls Contra? Did you pay your phone bill?? Are you wiping all data before flashing? Try the full second leak that they added to that post. I've been using it and haven't had the 3G drop in two days now. I just took that rom and removed a handful of apps I would never use. It's working quite well.

Fascinate poor reception

My verizon fascinate has always had good reception, even with different roms and kernels. I ran into something last week that made me have to factory wipe. Once I get root back and back to SC 2.9 and EC01 modem I've not been getting 3g service on a consistant basis. I can't access internet usually, email, or anything else relying on 3g. I can make calls, text, GPS. I tried different roms, kernels, reflashed EB01 radio, EC01 radio. No difference. What else can I try?
Did you set Airplane mode after flashing SC? I never had a problem but some people reported that they had to go into Airplane mode momentarily to correct reception issues.

Apologies if this is too basic -- did you already do the OTA *228, option 1, reboot, *228, option 2, reboot sequence? Hope this helps...
I tried Airplane mode and I had already tried *228. Neither attempt helped. I appreciate the suggestions though. I'm beginning to wonder if it's a Verizon problem. If I take it to the Verizon store for troubleshooting will it reflect that it is rooted? I know the warranty is not valid but will they refuse to help since it's rooted? I wonder if it would help to do a factory wipe again and start from scratch?

yes do this, or you can just do option 2 anytime you feel like it
this updates the Tower Roaming list for your area (from what I read)
Sadly, nothing I have ever tried has improved reception on my Fascinate. I hate to say it but I believe it's hardware at fault here due to a weak radio. It at times has gone from full bars 3G to 1x and back and the jumping up and down never stops.
mine has always had good reception but something happened and I have none where the day before I had strong 3g service. its usually not even showing the 1g/3g transfer bars indicator, just one or two signal bars without the 3g indicator. I used to use the email and internet at home before we got wifi to hook-up to but since last Saturday I can't connect at all without the wifi. So its not an issue of never having good service because I did before Saturday.

Vibrant randomly loses cell signal ( No network)

Hey guys,
My Vibrant is losing cell signal on its own. It happens randomly like once every couple days. I tried switching to Airplane mode but then I can't switch back to normal mode. This happened on stock, Trigger and Biwinning ROMs.
I have tried reseating the sim card but it still happens. I have also tried in GSM only and GSM and WCDMA mode but that doesn't help either.
The only fix that works is take out the battery and put it back in again. Does this mean I have a bad phone or is there something that can be done?
Are u wiping between flashes??
This has been happening to me on the stock Odin 2.2 build. Think it's the newer KB5 build. Samsung is so full of fail.

If you guys are talking about internet randomly stop working when your on the browser, then yes i can say i have data dropouts too. Im currently on modem KB5 idk if its that or t-mobiles network.
Flash different modem.

Oh I get that too, but I don't think the thread is talking about just data dropping. I woke up this morning to a completely disconnected phone. Not receiving calls. Not receiving texts (not that I ever get any). Nothing. No SIM card found. This after the phone was working perfectly the night before. Nothing changed.
It's really strange. Might try flashing another modem...would that help the SIM card not being recognized?
Thanks guys, I just tried Odin format repartition>KB5 stock and still got the error.
Now it's either the bad sim, kb5 sucks or my phone has a problem. I'm getting a new sim tomorrow

My phone went from 3G to EDGE to nothing in about an hour and I restarted the thing 2-3 times and nothing happened. When I finally went to work which is 15 miles away I had full signal no problem. Perhaps it's a network thing?

Thanks but I don't think its network, I get the same problem in Chicago as well. Also my wife's vibrant shows full signal. We traded sim cards and I still see the issue so its NOT sim card either. Now its narrowed down to:
1) KB-5 modem
2) Phone itself
I am still checking and will update the post

I'll Answer your choice....its choice 1) KB5 Modem. This modem is terrible i been using it on 3 different roms and while on this modem my data would freeze/stop randomly really noticeable on downloads and browser. I would be on the browser searching a page and all of a sudden it would not load anymore it would stop. I recently switched back to KB1 and my issues are solved no more data stops/drops. KB5 is really good on GPS but the data is horrible with the freezes/stops. Hope i helped you choose better. Stay away from KB5 if you notice browser loading stopping.

Thanks for sharing your feedback
Today I got the signal error on kb1. Sadly this seems to be a hardware issue with my phone. I also checked to see what my baseband version shows and it shows "unknown"
Then I checked my IMEI and I got "your imei is "" "
So yeah that sucks. The only way to get signal back is take out battery and put it back in.

I did, still the same issue...
I thought it was just me. It was horrible about 2 weeks ago. 2 different modems different solve the problem so I was convinced it was a network problem. I waited it out and they seemed to have fixed it. Instead if an x most of the day I have 1 or 2 bars of edge like before lol
Haven't noticed problems on KA6, but I haven't been using it heavily. (Switching between Vibrant and HD7)
Might be worth a try.
Edit: Also, have you tried Bionix? I know that the same phone never had any problems on 1.3.1. Think it has KB1 though, so it may not make a difference for you.
Sent from my SGH-T959 using XDA Premium App
Thanks guys, I did try Bionix nextgen which I believe is KA6 and didn't see the problem but again its just been 12 hours so far. I bought a dead vibrant with broken screen and just replaced the sim assembly. Let's see if that fixes the problem...
You're not alone. I have the same problem and I've flashed every modem I available. Sometimes I lose cell signal but not often. The data signal is what's spotty for me.
Thanks Blown89.
So when I lose signal, I tried checking IMEI *#06# and I get "null/null" and yes my efs is fine. Once I take out the battery and turn on the phone, it starts to work fine. Tried all software resets...
Any ideas?

[Q] Unable to make a call and several FC's?

I;m sorry if this has been discussed before but I can't seem to find an answer for it. I have an Epic and it works great except for minor problems usually resolved by looking through the forums. Although my dad has the exact same phone and I put whatever Rom I am currently using on his phone so that he can have a fantastic phone. He has had Frozen 1.1, 1.2 and Randomrom 2.2. They have all been istalled with Journaling on. The rom will work fine but then out of nowhere he will have FC's and will not be able to make phone calls but can still receive them. Any idea what is going on? We have the same phone, modem and rom but he seems to have problems. The only difference I can figure out is that he lives in an area that has NO signal for any carrier and so his phone is constantly switching back and forth from Sprint and roaming which of course drains his battery like crazy. Could that cause the phone to wig out on him no matter which software he is running. Thanks for any help provided.
Do you have an airave? If not Odin back to stock to see if it works then root and flash again.

They do not use an airwave and I have done several odin's and reflashed and still the same problem. I've tried to see if he is doing something before it happens to slueth it out but he it seems to happen at random times. It use to be just tons of FC's but figured it was due to haing journaling off so I fixed that but now he has less FC's sometimes but now with the unable to mae outgoing calls problem. I'm just frustrated because I try to help my family with their smartphones and they have nothing but problems with them but me, the one who actually plays on his phone too much, never has any seriuos problems.
It may just be the No signal area. If there is no signal it can't dial out. If there is no signal for any carrier then you can't even try Roam Control.

Issue with data connection dropping and text messages

Had regular galaxy s4 from att since it came out, never did any rooting or anything, updating to kitkat Ota when it was released and had no issues until about a week ago. I did a factory data reset because of too much junk on the phone and wanted to reorganize a bit, backed up everything using kies 3 and ever since then my data/signal cuts out randomly everyday, all day long. The more I text I noticed the more it drops, and then goes from LTE to 4g and it'll stay that way until some random amount of time, disconnect again, back to LTE once in a while but mostly be 4G. I heard of some issues with the kitkat update causing various issues like this but don't understand how a simple factory reset and restore screwed it all up or if it's even that. Tried full format, reflashing entire stock firmware and has done absolutely nothing for remedying the problem. Is it possible it's a sim card issue?

I have been having the same problems since I took an OTA update. LTE is very intermittent in places I know it is available and I randomly lose my cell connection for brief periods, which is a huge pain for SMS. I just flashed NB1 with ODIN and everything worked for the brief time before I updated to NC1 (LTE, no connection drop). When I updated to NC1 I started experiencing problems again. I subsequently tried flashing back to the NB1 modem to no avail
I tried ATT support at one point and they reset some stuff on their end (a while ago so I don't remember what) but that did nothing.
Anyone with any insight here would be my hero. This has been plaguing me since december.
Update: Tried re-flashing NC1 modem twice via ODIN with manual reboot. Still no LTE, not sure about connection drops yet.
Went to att store yesterday, thought maybe bad sim card, they replaced it and problem still persists... Looks like I'm getting the note 4 next month cause this is driving me crazy, so I guess I just need to put up with it until then.

+2 to this issue. My wife and I both have the same problem as you've described, and it's gotten progressively worse with time. The worst part is that the phone seems to think that cellular connectivity is still there as I still have bars. However, data, phone and text capabilities are all dead. The only fix is a reboot, and it's short lived.
I've read on another forum that disabling 3G and 4G eliminates the problem, but then you're stuck with basically no mobile data...
Anyone with advice, I'm willing to experiment!!!
It's hard to believe no one else is seeing this problem, or attempting to resolve it...
Wiped x3, flashed MDB mode and Odin'd back to stock MDB ROM. Let sit for an hour, then flashed back to stock NC1 ROM & Modem. Modem hang in less than a day...anyone else have any ideas how to fix these modem hangs? I don't have any ideas left.
Got the same problem. Mine started happening on MK2, so I updated to NB1 then immediately NC1. No change at all. I was concerned that it was because I'd rooted and was running Xposed framework and a bunch of modules. I was about to flashback to stock, but after reading some of you folks issues, I won't bother.
Looks like an upgrade sooner than later is in order.
