No 4G at all - Verizon Samsung Galaxy S III

I have an s3 that I flashed to CM10, AOKP 6 and I also tried synergy. I cannot seem to get LTE on the first 2 adn with synergy, I can only get it by using the phone info thing and switching to an LTE ONLY mode. I noticed when I was stock I didnt see it going to LTE either. is this a problem with it switching over or what? When I try to switch to the LTE ONLY mode on the other 2 roms, I get no connection at all.
Any ideas? Is the phone toast? I am an experienced flasher, as I am coming from a galaxy nexus lte and am a crack flasher. Before each rom, I wiped data, cache, dalvik and system.
anyone have ideas? I am at a loss.
thanks
edit: I also noticed that on CM10 and AOKP the activation fails, and I can skip it. My phone number shows up as unknown but I have an IMEI number

*#*#4636#*#*
Change to CDMA/LTE Auto

I did that and I noticed no change. I only have 3g

SAME THNG!!
I have the same problem and can't seem to find a solution!!!!

I'm having the same problem, I think. When I switch to an LTE option in phone info, it doesn't stay that option. it goes back to CDMA auto.
Can you just go to the verizon store and ask for a new one? Do they need to see your phone or anything like that, that will tell them its rooted?

I was afraid and flashed back to stock before taking it in, but the sim card thing is common. so just say you were told by customer service to come in and get a new sim and they will set you up. if you dont feel like going to the store, customer service will overnight you one, pretty much no questions asked. so its no big deal

This is a common problem... i had it too with synergy 1.2. The phone info app was stuck gets stuck on cdma . I had to flash the stock image through odin and flash synergy again. No new sim cards are required

Check your baseband then head to
http://forum.xda-developers.com/showthread.php?t=1788313 then flash a different radio.. meaning if you running LF2 then flash LG1 and vice versa. After i changed the modem i boot up into 3g went into phone info and chose lte only and 4g turned on.
When it happened to me i was running synergy (LG1-radio)...jellybomb theme..so there must be an issue there . i think its the jellybomb theme since it was made for sprint users

Pop up dialer, type *2767*3855#
and it will reset your 4G by fixing the SIM card - and immediately reboot. I've had the problem twice, and both times this key sequence fixed it. :highfive:

So a friend of mine was having the same issue. No 4G in an area I know he has full 4G signal. I reflashed the unrooted stock image in Odin (he was already stock, rooted, unlocked with cwm 6.xx) and still no dice. I tried flashing both radios, no dice. Also tried the dialing above to reset everything, nothing. Finally I gave up and told him to take it in into a store and they replaced the sim card and it worked! We then rerooted, unlocked, flashed cwm and all was good.
However, I asked him what all he had originally done after getting the phone so that we could try to take it step by step and see what caused it. I installed TiBu and lucky patcher as he had previously done (I don't condone pirating, espeically this great app but I wanted to try and recreate the issue) and it broke it, no 4G! I think the culprit was lucky patcher; I highly doubt TiBu could cause it as I have had no trouble with it. Only other rooted app he installed was adblock but again, I use this all the time with no troubles. I told him to just pay for the app! But I am still interested if anyone else might have had the same issue so we could try to prevent it for others? Any of you above who lost 4G did you by chance use lucky patcher?
Edit: Also, i noticed that I put the phone in 4G LTE only mode using phone info the 4G LTE symbol pops up but there are no signal bars. However, it appears as if there is signal since data speeds work fine and at normal LTE for this area so just the bars are screwed up, and then something with the hand off when switching back to normal off LTE only? Anyone else exeriencing this or have you tried to see if you actually have LTE even though you have no bars?

Same crap on my white 16gb gs3. Ridiculous data connections.

I have a replacement coming. They sent it a week ago and I got it yesterday and they sent me a nexus. Maybe its a sign to go back to the good ol gnex. They resent a gs3 so if the new one doesn't fix it I'm going to keep the gnex they sent and cut my loss

I just tried it coming from GB NexusMod 4 and just got the boot loop as well. It is a little tricky getting back into recovery - you only get about a second in the CWM menu before the phone spontaneously reboots.

Performed it fine here with zero issue.
If your cwm is acting up, may be lot more going on here.
I suggest a return to stock
Reflash cwm
Then flash this build.
Wish I could say more but UN able to see or confirm your issue.

Tmo
Hey, great base.
I have flashed this, the leak and a few other ics roms. On this rom I cannot get my phone to hook up to tmo 4g, edge works fine, but it wont jump from edge to 4g. I tried flashing a tmo radio but no dice.
The leak worked fine in that regard. Consistently connected to highest available signal.
what can I tweak in order to re-establish connection to tmo 4g.
I tried to go into mobile network settings and all of the settings there seem consistent with the stock tmo settings. But when i try to change network operator settings from automatic to manual it never gets past "searching"
Thanks for any help you might be able to lend
Also, i think this guy should credit The Collective.

IMEI restored, still no data

Trying to help a friend who lost his IMEI (showed as 0), I restored it with the QPST method successfully. All the numbers are there and the IMEI is correct, but it still doesn't have data. I tried calling the number in the older efs backup thread to reprovision, and it didn't seem to do anything, but while I was messing around with it the icon popped up and I had one bar of 4G, but it disappeared after a few seconds. I'm out of ideas and I would greatly appreciate any help. Thanks!

If on stock (root66 sounds) dial: *2767*3855#
Back up anything you may want on the internal storage before doing so. Should fix it if it's fixable.
This ^^^^.
I had lost mine also and followed the same instructions, got it all back, but no data return. You need to reprovision your phone by following the key sequence. I think you need to be stock to do it too (could be wrong). After doing that, all my stuff returned to 100% fully functional.
You definitely need to be on stock for it, though? What's it do specifically? I never outright lost my IMEI, but I did have a problem where data would intermittently cut out and it didn't display a phone number in the system info.
After a wipe and install it seemed to be okay, but now I'm without data. Phone number and all the other numbers are there, though. If I dialed that on CM10, what could I expect?

I already tried that, it didn't work. I just tried it again and it still didn't work, but I left it locked for a while and when I unlocked it, the 4G icon was there for a few seconds, and then went back to no signal and it hasn't come back.

Hmm if that doesn't work I'm not sure what else there is. Maybe a new SIM or phone, all I can think of
a new sim is needed, or you just have a data-bricked phone if that wont work... sorry bud
I'm not sure what it's doing, but I don't think it's unrecoverable. If I leave it for a while, when I unlock it I'll have a bit of 4G signal, then it disappears after a few seconds. I was able to use the browser while it had signal, but when I try to make a call it says "Mobile network unavailable." I did receive a few texts, I'll test sending them. Under Settings>About device>Status, all the numbers are there and everything looks normal except these:
Network - Searching for Service
Mobile network type - Unknown:0
Service state - Out of service
Mobile network state - Disconnected
Thanks for the help so far.

Have him activate another phone on his account and then reactivate the s3. I'm not sure if this will help. It's only a theory really! If you decide to try please Let me know if it works. Thanks

On mine, I restored to the Nandroid backup I made of the stock rom before switching and dialed the number mentioned before. That brought it back to out-of-the-box stock. Set it up, tested data, rooted, unlocked bootloader, installed CM10, tested data, restored apps, tested data, made another Nandroid backup, restored system apps and preferences, and everything's fine now.
My problem was really similar to that one, too. It started when the phone wasn't coming on when I pressed the home or power buttons, and after a battery pull it showed the phone number as "Unknown." A wipe and reinstall of CM10 showed all the correct numbers in the right places and seemed to fix it all, but data was back out in time. That was how it was every time I reinstalled that way; it'd work for a bit, then stop until I reinstalled again. Restoring my IMEI backup as a "just in case" hadn't helped either. Getting everything right again was arduous, but worth it.
Alright my dad has got a similar problem. He lost his IMEI before, we managed to get it restored and data working and all that good stuff. Well today he had to fly to Denver and put the phone into airplane mode, well when he came out of airplane mode it was stuck on roaming mode, and network is "Unknown" his IMEI, phone number, and all those numbers are correct but hes still stuck in roaming. We tried pulling the sim card, and going back to a root66 backup and then reprovisioning the phone. Any other ideas? Should he go back to complete 100% unrooted stock and then reprovision? Any help would be great
I've had the problem come back for me, so disregard my earlier post. I'm back on stock now with no data issues so far, so I'm going to sit on that for a bit to see if the problem is definitely with CM. It's been gradual every time I've fixed it; last time I lost LTE before 3G.

Restored a Nandroid. LTE isn't working though, so I may dial *2767*3855# to go back to full stock and see if that fixes it. Currently 3G is still okay.
A question...
Those losing their IMEI numbers... Is this happening on the locked bootloader? Unlocked bootloader? Both?
I've been digging through the forums trying to ferret out a pattern, but it's not presenting itself to me. Maybe someone else has seen the pattern?

[Q] !!Can't get on extended network!!

One of the reasons I came to Verizon was because in the basement where I work, they were the only carrier to get signal (runs off Sprint apparently).
Now, I'm running AOKP4 with VRLHE modem and I can no longer get signal. It just has an empty right triangle with the roaming R above it. Any ideas???:crying::crying:
To clarify, I do get signal outside of work. Just that inside, when I used to be able to get on extended, it no longer works.
If I flash back to F2 (I think was the stock modem), would think help my issue?
It could. Modems act differently. Now that u mention that I lost reception last night in a place that I never have before and I flashed the new modem like two days ago. If u try flashing back let me know if it works.

I had the exact same problem awhile back. I had to Odin back to stock and reprovision my phone by dialing *2767*3855# in order to get connected to extended network again. Dialing the code will wipe your phone if you choose to try that.
Flashing the modem didn't work. Looks like Odin is the next step.

[Q] At a loss, data but no voice/sms

I was running the latest stable version of CM10.1 on my GS3 and all was going well until someone sent me a text message and I tried to respond. I was greeted with the error of message not sent. I attempted to text someone else to have the same error. Attempting to call someone will just hang and eventually say call failed.
I thought it was a radio issue so attempted to flash different modems but had the same result. So I restored my previous rom Beans 11 that was working after wiping and the same issue. Data works perfect, but voice and text does not. I searched and odin'd back to stock VRLG1 and entered *2767*3855# in hopes of that fixing the problem, again no voice/text.
Any suggestions further help? I don't know what else to try!
*CM10.1 was working fine, and then calls/texting stopped but data continued to work without trouble.
*IMEI seems to be intact
*Flashed backup of known working rom and issue still persists
*Flashed back to VRLG1 and attempted *2767*3855# as per another post to no avail and this is where I sit.
Same thing. Installed jellybeans 12 now I can't call or text. Prior text was hit and miss some days....restored stock rooted image flashed other Roms....no help. Dialed the ** number....so screwed. Ayneegry should have backed up my few several times. No idea what to do.

When you say "Data" do you mean wifi or 3g/4g? If you have no phone/text/3g/4g then it's probably your imei. Check under phone settings, see if it's gone. If it's gone you gotta restore, do a search.
If you have 3g/4g then I don't know what the problem is. Sorry, just trying to help

I hear ya, if I can't figure out what's up, I'll end up having to go back to verizon and see what I can do... It was out of the blue, everything was working and then suddenly it just stopped. Happened on a flash that was a little over a day old, so who knows.
Check Mobile network
I have thiss problem happen occasionally when I flash custom roms. Look under your mobile networks, see if either CDMA/SIM is checked or NV. If NV is checked switch to CDMA/SIM and then reboot. That seems to fix that problem most of the time.
Edit: After some tests found out this doesn't always stick, but I did find out that after switching from NV to CDMA/SIM turn on airplane mode so the radios are tunred off, wait a few moments, then turn airplane mode off. That worked more consistently than restarting it.

Reboot phone and all should be well.

If you Odin back to the original stock unroofed ROM, you'd have to take all the ota Verizon updates to vmf1. Then reset your phone.

[Q] 4G LTE Not Working

Guys I've tried searching and tried damn near anything I can think of/find here on XDA and other sites.
Over the weekend I got a little sick of my GPS not locking on my Verizon Samsung Galaxy S3 SCH-I535. I was running CleanRom 7 and I believe I was on MB1 - I could be wrong on the basebad that I was on.
Anyways, after doing my normal reading to see what the latest and greatest things going on are I decided I wanted to do a complete wipe like I'd done in the past, update to MF1 firmware, update my radio to ML1, then put a fresh install of CleamRom 7 on there.
So I used to did a format of my external SD then a factory wipe/reset & cache wipe in CWR. I then went directly into Odin mode (Home Button/Volume Down/Power) and flashed the root66_VZW_I535VRBMA2.7z from this thread. I installed EzUnlocker and RomManager. I unlocked the phone, then flashed CWR. I first did a factory wipe/reset, I then flashed the MF1 firmware, followed by the ML1 radio, and finally Clean Rom 7.
Everything was fine except my 4G LTE would not turn on - 3G works fine but no 4G LTE. I've tried everything I could possibly think of. I've flashed to the prerooted MA2 linked above in Odin. I've tried the 2-3 suggestions in this thread, I've tried making my own APN settings, I've tried the thread which has links for people who are returning their phone to Verizon (plain jane stock). Nothing. All of those bring me the same result: Everything works perfectly fine, but the 4G LTE never shows up. It doesn't matter where I am - I know it is not a network outtage as people in the office have no issues and I always have a connection here and at home.
I've already ordered a new SIM card which should show up tomorrow but did I miss anything? I tried everything I could think of. As of right now I'm back at square one where I'd gone back to MA2, flashed MF1 + ML2 firmware, and back on Clean Rom 7. Stuck with 3G. Any suggestions?
Thanks!
Just Odin flashed the VRALG1 4.0 ICS to bring it back to stock found here in Section 5: http://forum.xda-developers.com/showthread.php?t=1762709. Still no luck.
Am I correct in saying when flashing that it is also flashing the modem/firmware? I want to make sure I'm not missing anything.
I had the same problem not too long ago. My issue was the PRL usually 4G PRL starts with 15xxx but if you go into settings-->about phone-->status you should check to see whether it is a 15xxx or 3xxxx. If the latter a new sim card should fix it right up.
