Possible modem toast? - Vibrant Q&A, Help & Troubleshooting

So, without writing a big long explanation, I'll cut straight to the chase and tell you what's been done with some light background.
I woke up one morning and my network was inactive. At first, I thought it was maybe some mobile network issue. One day later, still no connection.
-Odin'd back to stock twice
-reflashed multiple roms (including all the usual formats)
-flashed 5 difference ICS modems (KA5,6,7 and KB1,5)
IMEI error popped up after a new rom flash for those that are curious, but I lost my original a while ago and just adopted a generic. Never had an issue with it affecting my mobile network. I remember having a modem issue before when ICS was in it's discovery phase and flashing roms, but nothing where the modem just stopped while it was running/on.
I just wanted to see if I forgot something before I officially sentence my phone to death. I wanna say maybe a freak surge nuked it or something. That's about all I can think of since I know my way around android. Any ideas appreciated. maybe there's a way to check my hardware I forgot about.
Thanks!

[Q] Data Loss Ruining my GB experience :(

Hey,
I've been experiencing data connection loss on CM7-14/29, latest VGB, and PP (all MTD/AOSP GB ROMs).
Issue: Randomly, during the day, my internet dies, SMS/Voice appears unaffected.
This results in no connectivity on any apps, the 3G symbol is still there, but is white.
Turning it into airplane mode for 15s or so and then turning it back seems to fix the problem.
Attempted resolutions:
- Wifi sleep policy set to "never"
- Wifi sleep policy in spare parts set to "never"
- ESN swapped twice.
Anybody have any idea on what the hell I can do? BTW: My wifi is almost never on, so I don't think it's related to the WIFI handing off to 3G issue, because I RARELY use WIFI, and this happens (just happened again like 10 minutes ago), and there's no networks here it can even connect to, AND it's disabled.
I'm completely getting killed by this connection issue, b/c it stops randomly, then I don't get e-mail until I take notice that I'm not getting e-mail .
Pretty sure I'd take the SD card corruption issue AND the voice issue over this problem... :'(.
Problem resembles the invalild key issue that happens when switching ROMs, but the ESN swap twice (after two different ROMs were installed) seems to have ruled that out...or maybe I'm not doing something right about the ESN swap? Does the OTHER phone have to be activated during its time?
Anybody have any other fixes I can try?
EDIT:
Problem persists on all MTD AOSP GB ROMs, but right now I'm on CM7-29 with the EC09 modem, ESN swapped after modem flash.

I had the same problem try flashing back to a VZW rom (dl09,eb01, or ed05) and run it for a day and see if you have the same problem...I did and brought it into Verizon none the less with eb01...(not an official Verizon release) and they confirmed my modem was hosed...they over night'd me a new one and I sent the old one back with eb01 on it and they never gave me a problem!

I ran UKB 2.1 for like a week, last week. Not a hiccup. I don't think this is a HW issue, had no problems on UKB, nor OEM Froyo, nor OEM Eclair.
This is the second one (first one's camera HW was dead after like 2 weeks of use, verified by VZW), I really think the modem HW is fine, that's an issue with my setup or my process of flashing or something along those lines, still possibly key related for the authentication keys with Verizon if I'm not doing something right in the ESN swap process.
Maybe I'll try pushing a non-EC09 modem tonight (like ED05) and see if that fixes the issue, any other modems I should try? This problem sucks, just went to lunch, came back, no data *sigh*. Posted this right before I left for lunch (about 1.5 hours ago), right after it happened earlier...

idk man doesn't sound good. I am getting a replacement for mine (i somehow fried my modem/data or something?), but I just may never flash a rom again because ever since I started flashing my modem has become worse and worse... and now it is completely fried.
I have tried flashing a million modems before without a change, so I doubt that will help you. I would just recommend going BACK to what worked, and sticking with it, or you could fry your **** like I did.
i'm on miui 8.19 and every once in awhile i get a force close for android.phone and my 3g disappears too
I always had very weird data problems on 2.3 MIUI/CM7. The market would hang constantly or the browser would. I'd have to turn on airplane mode etc to get it back to normal.

Umm...ok.
Not trying to be a **** here but flashing the modem software has no impact on the modem hardware itself. Now, it is possible for modem firmware with an issue to cause damage, however, this is unlikely. The modem images are proprietary blobs swiped from OEMs, they're not tweaked by hackers in the Android community. I'm sure some OEM could figure out how to cause damage with one, but realistically they should be fine, even if the OEM was trying to kill it.
If your modem is getting worse and worse, regardless of what you did, it sounds like you had a hardware issue from the start. If that's the case, I'd suggest getting your phone replaced by VZW.
I would be extremely surprised if our problems are related. I'll keep it in mind, though.

Force close on what?
I don't get any force close, 3G just silently fades (not completely, goes from green to white). It still shows 1x or 3G accordingly, though. It's just white, hence, useless. Airplane mode for 10s fixes it.
Does this only happen on MIUI? Mine is pretty bad, happens like once an hour.

Yeah, I expect either of them to glitch or hang if there's no network connection present, I have no issues with that. I have an issue with the fact that there is no network connection present .

[Q] Urgent: suddenly lost my phone signal

Hi,
Sometime today I lost my phone signal on my SG2. I'm not sure exactly at what moment as I first noticed that I had a couple of bars but no 3G when I tried to browse the web. So I restarted the phone but to no avail. Since then I've lost all bars and can't make any calls either.
The only thing I have done today "out of the ordinary" was to connect to the phone using Wifi File Explorer to transfer a file, which I tried to connect to without being on a wifi network by first trying the "Wifi Direct settings" in Settings, which didn't work, and then by tethering by Wifi which worked. Maybe some setting got stuck in the process, but I'm not sure since never checked if it worked right before and after.
If anyone has any idea what could be wrong please let me know, as I am literally without a phone!
I recommend downloading http://www.androidzoom.com/android_applications/communication/no-signal-alert-pro_fyyo.html this will definitely be of benefit to you if your suffering from signal problems, it has been of good use to me.
Check your IMEI is the correct one for your phone .If not restore your backed up EFS folder .
Or try backup data and factory reset as a first step.
jje
Thanks for the quick replies!
The IMEI does not correspond to the one I have written down, though I'm not 100% I what have on my note is the latest IMEI; but how could that change though by itself, if my note is correct??
Also, I just saw something very strange: I turned on my phone and had full bars (no 3G though), and right in front of my eyes all bars dropped, one by one, during the course of 5-6 seconds. Something is VERY off...
Regarding factory reset: my phone is rooted (thanks to XDA!) and I have Tit.backup: can I will my phone still be rooted if I do a factory reset?
Something went probably wrong when rooting it (not neccesarily any errors) and effed up tge EFS folder.
Try to flash back to stock ROM, it might work to restore your.folder.

I should have been more clear on that, but I rooted the phone about a month ago and it has worked flawlessly since then, so it couldn't be that.
Anyway, I looked around a little and found this post:
http://androidforums.com/samsung-ga...connectivity-but-no-idea-why.html#post2722784
He seemed to have had the exact same problem that happened to me, so I decided to wait, and sure enough the connection reestablished itself about an hour ago and while I was watching for it, with the signal slowly creeping back up during a couple of minutes, and several hours after I lost it. Very odd.
This surely has to be an Android bug but that only shows up under certain and rare conditions.
To be sure I made a speed test and got 4.84 Mbps/up, 1.19 down, which I guess is fine; I never did one prior to this so I have nothing to compare to.
Again, appreciate the advice!
EDIT: For posterity, I should add that during these hours, even when I briefly apparently had a (non-3G) signal, I had a notification during all this time saying that I could only make emergency call.
I'm having the same issue. No Bars at all most of the time and when I have some, it never connects to 3G, G at most, and can't load any thing at all.
Very frustrating. I have been using Lite'ning rom 6.1 for a few months and had no problems at all until about a week ago.
I flashed back to a stock rom and still having the same issue.
I've also seen the bars drop down one by one in a 5 second window, bizarre!
Anyone find a fix for this? Or could the phone be faulty?

I was on Lite'ning about 3 weeks ago and actually completely lost signal several times. Reboots and hard resets solved the problem temporarily. I then flashed Batista FH 2.4 with ICS and things were great. I'm now on GingerMod. No issues.
I don't know how it could be kernel related though, especially if you are 100% stock again.

[Q] Suddenly not getting any signal at all for no discernible reason

Ok, so here's the scoop.
Earlier today for no reason that I can pinpoint I lost all Cellular connectivity on my photon while at work. No calling, no 3G, etc. I figured it was just a hiccup or possibly that they where working on the towers in my area and that it would eventually just come back up.
That was over 12 hours ago, and I have already traveled from work, to home and still no change.
I began to think that maybe my PRL was out of date, so I flashed back to a blur based Rom that has worked for me in the past (I normally use CWM7.2 and moved to Imperium_Initiative_v1.0.5 to try and do this) and tried to initiate the update there.
Still, no results. Not only would the PRL & profile not update but I got a general "NETWORK_ERROR" every time I attempted to do so.
I'm getting a little desperate because I really need to have my phone active for work and other reasons.
I've already restored old NAND backups, restarted the phone numerous times, and so far nothing is working...
If it is indeed a PRL issue, is there a way to manually flash an updated version onto the phone?
Any help that anyone can offer is greatly appreciated!

P.S. The only major change that has been made to the phone recently was I purchased a new extended battery about a month back. It's been working great since I broke it in, and have no so much as flashed a new rom image since I got it. It's the Trexcell Motorola Photon 3570mah Extended Battery.
Well I decided to bite the bullet and do a full re-lock and stock re-flash and I now have gotten my signal back.
Still have no idea why it happened to begin with, but I have apparently solved my issue.
If anyone can give me a reason this might have happened then at least this topic can be of future use to someone else.

This happened to me once while on cm7, again, for no apparent reason. After being baffled for an hour i got pissed and went to bed thinking my radio died. Signal was back by morning. Id be willing to bet yours would have come back too. Pawn it off as a hiccup and keep flashin stuffs.

Serious data connection problem

Hi there! With SGS III being my third from the Galaxy family, I did not waste any time and flashed first custom rom the very hour I bought the phone. Everything was really great - I've been through Android Revolution, Omega, Wanam and couple more, but it all seemed too good to be true. Two days ago somethig went wrong with my data connection - I noticed it while I couldn't connect to Facebook. The "H" icon was in place and by the arrows I saw that it was "working" all the time. The problem was (and still is) that no data actually goes through. I tried different radios, kernels and roms - to no avail. I've read something about botched or misplaced IMEI issue, but checked it right after that and it is intact. To be sure I tested my SIM card in other phone and the data connection is working flawlessly. APNs checked. I'm getting quite nervous because I've only got my SGS III for three days and already it's.. Not entirely functional.
If you have any idea what this may be about, I'm happy to provide any information needed to identify my problem. Thanks in advance for saving my S III..
Sad to hear, unfortunately it seems you already tried the common solutions to solve such an issue, the only additional thing coming to my mind is to flash a stock Rom with odin, if it doesn't work do the same with a pit file or change your csc, because the last two options reset your whole user data to stock and your internal sd as well (don't forget to backup your data) it should solve it.
Maybe there is somewhere a leftover which causes your problem, good luck

Flash a stock rom with Odin and perform a full wipe *2767*3855# in the phone dialpad. Save important files to the pc first. This should fix it all. You can reroot after that and make a cwm backup of your stock rom.
-Edit- double post, Follow the above
Thank you both for your suggestions, but it seems that I'm stuck with I-do-not-know-what.. :/ Flashed stock rom and new radio via ODIN, but the problem with really slow HSDPA connection is still present. I am worried it might have something do do with IMEI after all - it seems that here http://forum.xda-developers.com/showpost.php?p=29461950&postcount=3 they are explaining similar issue, but I haven't lost my IMEI (not to mention backuping nor restoring anything). What is more, I do not only have EDGE icon, but HSDPA as well, but the connection is slower than GPRS. Damn it..

[Q] Help - Service Not Working

I work with a guy that owns an ATT m7. He isnt too knowledgeable on rooting however he does flash his own roms and has some idea about it all. he told me he bricked his phone and thinks that after flashing so many roms he fried something with the radio. The phone does not receive a signal.
I took the phone home for him to fix. Just to test I flashed CM11 and just as he said radio was not working. It showed bars but if i tried to make a call it didnt work. I figured this would happen anyways so i carried on with obtaining s-off. I then flashed a 4.1.2 RUU. I put my sim card in (straightalk) and at first it didnt work. after a few minutes I looked again and vuala I had service. I added in my APN and everything seemed to go smooth. I did notice that periodically I would look at the phone and see it said "emergency calls only" but it quickly fixed itself (my s4 does the same thing so it could just be my area)
I used the phone all day and it seemed to be fine. Texts and calls worked perfectly. Feeling confident I then rooted and installed twrp. I backed up the stock rom and flashed CM.
No service.....
Anyone have any clue whats going on? I am currently RUUing again to see if it will work again and I am sure it will.
Im having trouble understanding this issue as I feel that if there was a mismatched radio then RUU fixed it. How would CM make this not work? Only thing I havent tried is a different rom (this was a nightly so i dont know if it has an issue) I just really don't feel like going through all the trouble again just to find out its not the ROM.
Hopefully someone has some insite.
Something is wrong with the software hes using if working on regular sense build and not cm,best aaking in the rom developers thread.

Yes but after 4.1.2 RUU it still cuts data on and off. Is it possible it's a bad radio or should we try a differentRUU?U
first id say get to an area where the radio reception is better, get an att card and not straight talk and test.this could very well be a hardware issue as well, but it seems more of a simcard issue/software issue than a hardware issue
