BIG PROBLEMS, no 3G/4G mobile service since yesterday, tried EVERYTHING

Need some help here. I never usually need help, been modding everything possible on Android for years now. But can't figure this one out, getting worried.
Had my LTE Nexus since launch day. No issues like this before.
Been on all Team Kang AOKP toro ROM updates since release, always on the latest. Stock kernel. Was on build 20 since it came out.
Yesterday at work, had a few bugs from probably not data wiping from build 19, so I wiped it all and re-flashed 20 again. Restored Titanium and started re-setting things up, I believe these are the only things I did. I was at work where I would normally have minimal, but some, service.
Ever since around there, I have not once had a bit of 3G or 4G service. I have not seen the 3G logo for even an instant, only few, gray bars. Wifi works fine of course. It's possible I even lost service before wiping and re-flashing, but I can't recall or didn't notice.
I tried all the usual stuff, wiping everything again, re-flashed AOKP 20, re-flashed other/older ROMs, re-flashed latest radio, restored old Nandroid backups, pulled battery and sim card and put back/rebooted...NOTHING IS WORKING. Also, I have driven through several towns since yesterday so I know it's not a local outage. Also, other people with Verizon phones here have service fine.
I have basically torn the phone down software-wise and nothing has fixed the issue. I still have no service. Each time I re-flash a ROM, it always makes me go on Wifi when it wants me to sign into Google...it never picks up mobile service then or after.
The About>Status screen says:
Network: Verizon Wireless
Signal Strength: shows an actual number reading that changes
Service State: In Service
Roaming: Not roaming
Mobile network state: Disconnected
Please suggest things I can try, but I guaranteed I have already tried them. Can't understand or imagine what is causing this, because I did nothing different than I normally do.

Also, I posted this on Rootz as well, and many replies so far. Still no luck though.
If you have an idea I can try, maybe post there instead at this point for me?
Thanks guys in advance.

It seems a radio problem. Try to flash the stock ROM from Google.

Well I did go back to many random earlier, more stock custom ROMs in hopes of a fix, but nothing so far. I am currently back on the stock 4.0.2 ROM that is rooted and deodexed by Bigxie, but I guess I can go all the way back to stock 4.0.1 or 0.2. Will try now.

Went to Verizon and it looks like the sim card swap did it. The girl there was nice and did it without hesitation for me.
She showed me in her computer how under my family account, it wasn't even fully showing my device or something like that. Not sure if it wasn't there at all or if it just didn't show that I had a 4g phone activated on the account...but I'm sure it was related.
Sucks to have to get a swap and still don't know what caused it or if its related to flashing roms, but at least it works! No issues since...

It is possible, but unlikely and no reasonable explanation, that your sim somehow got affected doing all the flashing and stuff.

I have the same problem, every now and then it will stop having service and the only way to get it back is by rebooting, sometimes it works at first sometimes it needs a couple of reboots.
Any hint with this would be great
(this happened to me with aokp and cyanogenmod)

I have the same problem but it stopped having service at all, and it's not a sim card problem (the same simcard works in another phone)

same problem and i'm having invalid imei

im having almost identical problems... like a month or 2 ago i reflashed to the new 4.3 slim rom. I have been fighting this thing every since. Ive tried so many different radios but yet i still have this issue, sometimes i can go days without problems but now it seems to loose data even sooner. ONLY way i get data (4G) back is if i reboot. Ive tried disabling then re-enabling data, same for airplane mode, nothing works. I think part of the problem is this damn rom.... i used to be on black bean 8 and for the mobile networks it had an option for "CDMA/LTE". This rom must be a ported rom cause the only selection for mobile networks that work is "CDMA/EvDo/GSM/WCDMA". I am on Sprint CDMA and LTE. i dont understand why this was done like this. I Would like to go back to blackbean 8 but i had problems with it and i like some of the settings for this rom better. Anybody have any ideas? Ive tried ALL the radios, none seem to be stable.
oh and i would post in there for the rom's forum but seeing as i havent posted enough here im not able to ask questions about it or anything :-/

[Q] 5 mbps wifi speed

ok, googled the past couple months with no results. searching here still no results...
my s3 seems to have sluggish wifi wherever i go, no matter what modem, no matter how many settings i changed advised by posts ive found. *#0011# turning off psm does not work. changing advanced settings will not, static ip does not, flashing roms tw or aosp only same results in all.
im beginning to think this is a hardware problem, not software. cant get a new one cause i don't find it a need for insurance cause if something breaks its cheaper to fix ordering online, plus the fun doing it yourself.
does anyone know if we ever had a flash-able zip to fix like the international version? tried and bricked of course. or any steps that i haven't posted i didn't find searching?

Is it a newer one or an older one? The reason I ask is because all S3s are not built the same. I've had mine since they 1st came out, and have never had 1 issue with wifi speed. I just rooted a newer Sprint 1 and a Boost 1, both of them had wifi issues even after I set a static IP for each on my network.

its the newer build. forgot to mention zeroed out some of the http settings in ##data# for the speed boost. 4g zips.
i cant even find a diagram online to find where any wifi chips are located. went as far as taking a heat gun to the board itself and applying weight to it after like the famous ps3 fat fix. yea, i went that far lol:silly:

[Q]Please Serious tech help! cellular data radio unresponsive

Look i normally dont ask for to much help ive been around a bit know more then the average bear. I also fix hardware.
My problem is my data radio will not switch on from any attempt:
Attempted solutions:
Dialed
*#*#4636#*#*
Will not switch on from that screen
Did the obvious and switched on and off airplane mode
Replaced the entire build.prop file with a very stock build.prop after flashing stock jelly bean
Repeated steps for all stock firmware
Newest attempt wiped the entire system partition through recovery forcefully bricking the phone. I have now flashed the original stock e980 stock 10p tot file still no luck
My phone is completely unlocked fully rooted.
I've replaced the data permission files.
And I know its not the SIM card because the SIM card is in the phone I'm using right now which is an LG g2 unlocked which is for sale by the way.
And if it is a hardware problem I have not found any related video or thread to help me find an exchange where the radio is on this thing
Help me please if anybody has any idea?

Cool no help, hey moderator can u move this to thread that may get more help that would be awesome

i came looking around here because my g pros radio stopped working sometime last night while i was asleep and was about to make a thread asking for help, but seeing as how you haven't got much i doubt i would either. but ill give you a little info on mine, will it help you out at all? not sure. but i know it might make me feel a little better.
I flashed Vanir 4.4.4 last week coming from Beanstalk 4.4.4 cause beanstalk was getting buggy from all the ugly mods i subjected it to. so all was well with Vanir till i woke up this morning and had no service, no calls, no network, AND even if i connected to a wifi network it seemed that i couldn't get any data from it. I tried flashing madmacks modem cause who knows, maybe thatll help, but it diddnt. So then i flashed a different kernel and changed TCP protocols cause who ****ing knows, but it did nothing. THEN i restored my older Beanstalk 4.4.4 backup sure that it would work flawlessly but guess what, same problem. Now that im back on Beanstalk i went to the "Network Operators" option under "Mobile network settings" and selected ATT, which is my service provider, i can now make calls and texts but still no data, when i did this on Vanir it did not help. So i started messing with my "preferred network type" and realized i have data on 2G, but not 3G or LTE. Im gonna take a wild guess and say that maybe if you flash your phone back to 100% stock your radio should start working again, as much as i dont want to, i might end up doing that as well.
tl:dr
similar problem, i dont really know ****, easiest option = go back to stock, hope it works.

@Fant0m3 @alb-o
Have you guys checked if your rom shows your imei?
I have had this problem twice. My IMEI disappeared and I don't know how.
Your symptoms match.
If that's the case you could take it to a repair shop and they'll fix it in a minute or two. Or, you can check around xda.

thats a good point, when i was looking around XDA earlier i saw a few mentions of it but diddnt see anything very specific and was late for class so diddnt have time to look for too long. strangely enough mine actually started working normally again after i kept switching from 2G to 3G to LTE, which is great. but if i would've known that info earlier i could have checked if my IMEI disappeared while my radio still wasn't working, i assume it probably did.
after searching around more i found this thread that talks about it and how to prevent it:

thanks for the help g0at1, hopefully this helps out the OP if he hasn't already fixed the problem, or anyone else that comes across this.

nope
I've flashed back stock numerous times even flashed other versions such as e988 and back again if u dint know how to do that just change your build number in your build prop file...I've tried everything I am downt to antenna cable SIM reader or cell radio.. If radio I might as well just give up cause I can't find one for sell anywhere...I'm not so pressed as I'm using the LG g2 and it's so fast stable and a bit slimmer I think I'm gonna keep it but I would like to fix it and sell it though...... My symptoms are mentioned and all tried fixes are there. Imei is read carrier is not WiFi is received but there is an X above the data bars phone is fully unlocked as well

This may help also but it does not read my imei when the SIM is not in hmm maybe I will rework the imei code and get back if that works. I will keep updated when fixed and with solution

Data Issue in Custom ROMs

Hi all,
I tried almost all pie and 10 ROMs for 5Z and they all work great.
However, in all my flashing endeavors, I had data issues in some ROMs; like the data won't work at all, even after setting up the correct APN (RIL works perfectly fine).
Interestingly this bug (don't know what to call it) is random, if i flash the same ROM again and if I am lucky the data works just fine; it's a total hit and miss and it is just plain annoying. Although, there is absolutely no data problem on stock (any vendor) but this happens if I try and flash any ROM.
Any advise? what can i do to sort this out?

I had similar problem, but the problem was Roaming. Out of the country i was not able to use 3G/4G. I tried all customs roms, but it was still the same issue. So i went back to stock and it works without any problems.

Same here. All roms worked pretty well (e.gL ineage, Havoc) except for Android Auto and roaming. Data worked, except when roaming. Was never able to get a connection. Back to stock all worked. Could not find a solution.

Precisely the problem.
Is there anyway you got it to work or figured out to make it work?
I honestly hate the stock ROM and would love to use an Android 10 ROM.
