No Service Selected network (AT&T) unavailable! No Signal

I flashed in JB AOKP was working fine all of last night. I also entered my SIM Pin or unlock code. The first time I put in an 8 digit unlock code I have. Second time it prompted me I skipped it. I'm pretty sure it was the security pin and not the network unlock. I don't have any other phone's micro SIM I can insert into my phone and a local phone store's T Mobile SIM produced no different of a result except for replacing AT&T with T-Mobile (I have not however put my microSIM into another phone...because I don't have another micro sim phone). Reboot phone this morning and it's no longer working. Tried to enable 2g. Nothing. Tried a battery pull with the phone on, pulling the SIM (same message with SIM pulled out),
Wifi works
This sucks big time ;(
Note: I am pretty sure I did not network lock the phone or anything because the SIM prompt that came up when I flashed JB did not ask me for my unlock or network code (I would have known). The first time I entered that code was 'just in case it's asking me to unlock" but why would it ask me a second time then? So I doubt it was prompting me for a network unlock code. The prompt from youtube videos was different too.
Also APN is empty, but I think that's becasue I'm not connected to any network
Pressing Available networks brings up AT&T AT&T AT&T T-Mobile T-Mobile "311660" pressing any of them you get a quick window connect "too fast" goes back to/stays in available networks screen and says "Can't connect to this network right now. Try again later."
So I added the AOKP and Corresponding kernel yesterday and I mean it was working fine with 4g... apparently this thread says that you need to flash a new radio in some cases when you change kernels?

...what are you talking about. My IMEI isn't mentioned once in that post. In fact now that you mention it, since people's IMEI changed...nothing like that my phone still has its IMEI
I also did not get a "phone frozen" from entering the wrong code too many times...so I doubt its locked like that. There was a random reboot that I WOKE UP to, but nothing weird...it rebooted randomly but worked finely after that

I was proposing the theory that you may have lost your IMEI, since the symptoms you report were very similar to what I was experiencing when I lost mine, however since you still have yours, must be something else, eh?

Just flashed an old version of the same rom...still nothing, although this version had 4g lte working for sure gonna try one more flash of the same rom with only some system settings moved around.. I actually need this phone to travel to Europe ;( ffs worst time

Well, mine was definitely due to a lost imei that happened sometime when flashing.
I did get the network unlock warning thingy twice, and then had no cellular connectivity, which is why I mentioned the lost imei. I restored my nandroid back to stock, then used the method here with a little driver tapdancing to reinject my imei, and that solved my issues, but sounds like you have something else going on.

If I flash back to stock and no longer have the stock kernel, what is the steps for flashing back then?
1. flash stock kernel
2 fix partitions
3. factory rest/cache/davlik
reboot into oden and flash new image?

Long story short, Don't cut your own microsd..the sim pins on this phone are VERY sensitive and hard to fix/see. Don't bend em.

I am having the same problems right now, I keep on getting " NO SERVICE" - SELECTED NETWORK UNAVAILABLE" Error.
Rebooting doesnt help, flashing modem through CWM doesnt help. I know for a fact that the simcard it good because other apps that I install can read the sim with no problem, and my WIFI is working like a charm.
Someone got a solution for this? This is already like 4 days ongoing, please any help will be appreciated !!

Im having the same no service selected network issue. I can search and find att and the mobile but when I try to have it connect to att that's the error I get. I have an att SIM card in the phone. Sph l720 SIM unlocked, it didn't ask me for an unlock code or anything like that but I also don't get the invalid SIM card error. I've added the main apn from the att website but that doesn't help and the phone is current set to gsm/umts. If anyone has a fix please let me know, thank you.

D850 cant connect to GSM. stuck at "No Service"

We had a few hours network outage due to security reasons. But my G3 didnt recover when the outage was over and is still stuck at "no Service" even after several reboots, clean flash of cloudy and restoration to stock using nandroid. It was working just fine a night before. I have tried restoring Stock from nandroid but still no luck. I have tried different SIM cards too but still no connectivity.
*#06# shows proper IMEI number.
Any clue what might be wrong and how to go about fixing it ?

Update ::
OK So I looked around. my IMEI is correct. my wifi and bluetooth mac addresses are ok. but my baseband is shown as unknown. So i flashed a modem from here for v10D D850 and now I am not getting "No service" but still not getting any network

My suggestion is flash stock Rom with kdz or tot method. Look under general section and return completely stock.

OK so I am back to stock using TOT method. I have my IMEI, baseband and MAC addresses intact. Now it doesn't say No service rather it keeps on searching for signal and catches some from time to time but loses it again in a jiffy. Sim Toolkit is working fine so I assume SIM jacket isn't the trouble maker here.
search for signals :::: get a lock on :::: lose the signal :::: repeat
Any clues ?

Turn on airplane mode on and off. Factory reset your device from settings menu. It's a weird problem. It must be fixed after tot method.

Are you using it on At&t? Maybe sim gone bad or imei blacklisted by accident.

Which ATT APN are you currently using?

I'm actually having this exact problem to right now, I flashed back to stock and I still receive no data. I've tried nextgenphone APN and the PTA APN, I also checked my IMEI and it's fine to.
Edit:
I'm using an AT&T LG D850
When I put the sim card into my Moto G, it picks up 3G and works.

Ok so after having my go at the phone i had it given for repairs. The guy said he has replaced antenna multiplexer ic which has solved the problem.

I am experiencing the exact same issue but with a D855.
I decided to go from stock to CM12.1. This didn't end up working. Stuck on Bootloop. I also tried Xenon HD and had the same issue. So I came back to stock. Now having this issue.
What I did was flash from 5.0 to 4.4 so that I could root. I was unable to on 5.0.
Then I rooted using LG One click Root.
Then I flashed the latest TWRP
Then I did a full clean in TWRP and flashed CM & GAPPS (same with Xenon)
When this didn't work, I flashed to stock using LG FLash tool.
I tried both the KDZ and TOT methods numerous times, also tried to re-flash CM & Xenon and had the same issues.
I also tried flashing stock 4.4 and 5.0 roms and still the same.
I have also done multiple factory resets after flashing.
If anyone out there has solved this issue without sending their phone away, please advise as I am at my wits end and without a working phone.
Thanks

Got it repaired from Singapore Plaza Rawalpindi for 3k. Shop name was X-cell

[Q] disappeared LTE all firmware

What is done:
first I flash 30B bump, the problems starte. then flash 30B LGUp, flash 21a and 21c, change band in ingeneering menu, delete lteconfig, flash 30b bump with modems: 21a, 21c, 30b hybrid, change of operator, manual config APN, manual search network. All this does not help.
Any ideas?

no ideas?

Idem.
But after reboot 4G is ok, but again...every morning i lost signal 4G...only 2G/3G is ok. So..reboot & 4G is up......disappointed.

Same on my G3. I downgrade from MM to LP but problem persist.

Same here....tried rollback to kitkat stock, LP stock, CM12, Cm13, and some other roms with no luck....have just flashed stock LP for repair...

so today I tried swapping my SIM with my friend's
he is using G3 with stock 21A, and his SIM is of the same carrier as mine
after swapping, I found that my phone (and of course his phone, too) is working normally
my phone is normal even after swapping back
did some different tests like switching on and off with 3G, LTE etc., everything is normal, at least at this moment

Still working with you? So it is sim card fault? With me after searching networks everything seems to be ok, but I couldn't connect with LTE. Only sometimes successfull connection.(once a day and after reboot same...) Very strange. :/

I lost network signal randomly... i tried with 30b hybrid modem, 21a, 21c... kdz method, twrp bumped rom... and doesnt help me at all.. my network signal gets a rotating circle randomly... and in that time my phone is out of coverage... it is .... hundred times in a day... i dont know what to do, please help

same here when i use sucks 30b D855, but now everything is ok with me.
Steps that have been followed:
downgrade to lollipop 5.0
install CandySIX Rom , then try to connect to my carrier network , at the first time it not give me anything , but when i reboot my phone , LTE appears and everything fine
back to CloudyG3 2.5 then i found that the problem resolved
My phone now works well

OKAY, i found a solution to the problem and here is what i found :
Pacote-san said:
Same here...
Edited: Fixed this deletings the folder LTEconfigs on System/app
Had to then configure it to auto GSM/WCDMA then switch back to LTE auto
It connected at first with 3g then it went LTE and worked normally

Some people got their phones back to normal by flashing some roms (like CM, ACIP, stock, etc.), but that didn't work for mine
not sure if it was sim card fault, but my problem solved (at that time i was back to LP stock 20h) after swapping my sim cards with my friend's.
i am still using that sim card at this moment, working fine since last thursday

Same problem here, have signal drops on MM roms with LTE connection.
Tried all methods above, nothing really helps .. ;((
The signal is fine on LP roms, tho i installed N&N so i was able to change network type to GSM/WCDMA auto, having steady signal now, but missing LTE speed, trying to find solution to fix this, but unfortunately for now.

Same, my G3 doesn't recognize my sim sometimes or it just loses signal randomly, making the smartphone almost useless.
I tried CloudyG3 2.5 Lollipop, then upgrading to Marshmallow with many radios flashed (also the hybrid one) , then I tried to come back to a stock Lollipop ROM and the signal is always unstable. I'm going crazy due to that. I'm starting to lose hope too.

I think I've tried every possible solution to the connectivity problems I've read since flashing 30b.
Freezing LteConfigs gave me more stability, but didn't solve the problem completely. Tried editing the build.prop to force LTE as preferred network type, this didn't change anything. Don't even know how many times I've changed my apn settings.
Tried every combination of modems possible: 21a/c modem with 30b rpm/tz, pure 21a/c, pure brazilian 20c, brazilian 20c with 30b rpm/tz and nothing. Changed sims multiple times, didn't work.
The only way to get a reliable connection is to limit the phone to 3G... but that isn't a solution since I pay for unlimited 4G. If I let the phone in auto mode, the instant it tries to connect I lose all connectivity and it would take up to 2 minutes searching for the network.
I'll flash the stock rom today and if it doesn't work I can safely say it should be a hardware problem.

I had exactly the same problems I tried all of the solutions mentioned modems/roms/etc but what solved it for me was flashing the Pure stock MM kdz now no signal drops or 4g problems.

Did you root after flashing the kdz? I'll try with pure 30B but having no root is almost as bad as no 4G.

No not rooted it yet, to be honest I don't like the kingroot app it looks way too suspicious to me + the rom is smooth and stable at the moment so I thought I would stick with stock for a while.

Have u rooted. Flashed a rom? Is it network unlocked if not on orig device carrier? And if just pirchased are u sure its not black listed?

it is not black listed.
It all began when it started on all the time.
Now it has not started on all the time at 24 hours now.
And I flashed a ROM.
After that, you will not signal more than a few seconds, then you can not register on the network.
Have tried with APN that I know works, but not on this phone can only use wifi.Jag checked with the operator and they have no problems.
Have tried with different SIM cards without result.
my simcard worked with the phone before it started on all the time and I installed a ROM tried olkia rum with the same result.

May have flashed a rom with a incompatible modem. Try using flashtool lgup and going back 100% stock. But be sure to make sure ure not downgrading to a incompatible version or brick could result. Find out what version qfuse ure bootloader is and find stock rom to match.

"No Service" despite a functioning SIM card being inserted

Hi all,
I was running on Fulmics 7.6 for close to a year now, and since it was my backup phone, it was usually on Wi-Fi. But I was able to use my Cricket SIM card before, until yesterday. I got a new SIM card from US Mobile, popped it in, and to my surprise: no data. I got the "No Service" message at the bottom of the notification drawer, and it said "Service disabled" at the top of the lock screen. When I try to update the APN, the "Mobile Networks" option is greyed out. I updated to Fulmics 8.0 and that didn't seem to work. I tried flashing Xceed kernel since some posts said a new kernel would help, and that didn't work. I wiped everything in TWRP, and reflashed, and that didn't work.
I was able to get data to work for a few minutes, when someone suggested using paper on top of the SIM card. After I restarted the phone... data did not work again. Then this morning, I updated Magisk from 13.3 (I think that's what was in Fulmics 8.0) to 15.7, and that got data to work again... but when I updated Magisk Manager to 5.7, data stopped working.
I've since tried clean installing Fulmics 8.0, updating Magisk but not the Manager, and even unrooted my phone and rerooted it. Still no dice. I'm drawing blanks here. The phone clearly detects the SIM, but it insists on not receiving data for some reason. I tried this with 2 different SIM cards that work in my other phones, so I'm not sure what the issue is here.

Probably, simcard slot is broken. Mine LG G3 MB got warranty change, because that problem was same like on yours phone

have you tried without simcard and did you see no serivce or no sim inserted?

If the SIM card is in, it says "service disabled". Without the SIM card, it says "No SIM inserted"
