Hey guys, I was using AOSP Extended 5.8 for some weeks without issue. Worked perfetly.
Today the phone woke up without no cellular signal. The phone was very hot and battery was decreasing rapidly.
In the past weeks battery life was amazing.
I removed the SIM, rebooted the phone multiple times, wiped cache etc. Nothing worked.
Tried the SIM in another phone, radio/signal perfect.
Reverted to stock indian rom, still no signal.
Stats says the Radio's off.
Is this a hardware issue? Or can it be solved without changing parts? Why does this happen?
IMEI numbers are appearing correctly. I tried a few custom and stock roms, without luck...
When I try to call, it says it's in airplane mode. *#*#4636#*#* says the Radio's off. If I ask to turn on, it doesn't do anything.
Thanks!
Did you check whether IMEI of the phone was showing in settings> about phone? If so mostly baseband corrupt. Will have to restore EFS backup from twrp or use some IMEI wite tool to write ur original IMEI into the EFS partition.
Facing the same issue
Did u find any solution for this. I searched on zui forums and they suggested to open the back panel and heat the shielded part where the radio chip is.

My phone modem randomly shuts itself, I think.
My phone was broken about a month ago, no efs backup, generic imei, 00000 serial number. It was fixed by a local shop who has those "boxes".
It was formatted to the early iterations of JB 4.1.2. DMA1 I think. I then updated it through OTA to the latest version DMC3.
Then it happened. My messages would suddenly be lost. I dialed *102# in the dialer then it hangs, The signal icon would then be the circle icon like those in no parking signs after 10 sec. This method actually forces the modem to restart. Then all would be okay again like nothing happened. All messages are intact.
I flashed the stock rom thinking it would repair the problem but I mistakenly flashed Dr Ketans pre rooted rom marked XME which is for Malaysia. Flashed the proper firmware from Sammobile, XTE for the Philippines. No Signal. Restored using the efs I backed up after my phone got repaired. Emergency Calls Only. Installed Ariza Patch. Got my signal back, Imei normal, Serial Number Normal, but my Baseband Version shows Ariza_NII_[V.01].
I thought I fixed my problem but its still there. It still randomly hangs while Im texting.
Could it be a Kernel Problem? What Kernel could you suggest?
Could it be a bug in the messaging and phone app? Even for Google Play apps, it hangs, looses my messages.
Has anyone encountered such?
I would post a video if it happened again.
Please HELP!
hi, first of all: I have been searching for solution to this problem for ages but the problem still persists
I bought the phone a while ago, worked pretty much perfect, I experienced some random signal lost but right after restarting or some minutes the signal went back, so after some months and after changing my phone screen my signal disappeared completly It once worked with my friend's sim card but just with that card and just one time, I tried differente sim's and operators but got no sucess, the phone recognizes the sim but the signal strenght is null (X)
I already tried the following options:
reset
hardreset
5 different roms (cyanogen, and some stock 975/977 roms)
flashing another modem
4 differente sim's
didnt tried anything related to the kernel, this may solve my problem? seens like my problem is related to hardware problems, I dont know..
additional info: my imei is not blocked or N/A but my phone cant recognize my sim number
Additional info: on the fastboot menu the baseband is "N/A", is that value normal?
Thanks in advance:
My phone started turning on and off its 3g connection. Wifi works solid.
I'm on a good signal area. It's not like the 3g is on and I can't connect in anything.
The problem is that the phone turns on and off. It doesnt fix the 3g connection.
Also, Checkin service it's draining the battery a lot.
Looks like a software problem with Google Play Services and its Connection checking service.
Anybody have seen this problem?
thanks in advance.
Starting to worry right now. Did a factory reset on a flashed V10j KDZ and it didn't change.
TWRPed a 20A Lollipop rooted ZIP and it didn't change. Right now I'm trying to go back stock using LG PC Suite.
I can't understand why this can be a hardware problem because 3G actually works but it keeps constantly getting on/off in ~10 seconds intervals.
Looks like a bad system file that is messing with it.
EDIT: Also, the phone can't search for mobile networks anymore. I just tell it to do a manual search and it can't find anything.
What would this be? Modem file broke? WTH.

I have random disconnects/drops too, Although my 3G/LTE icon never actually goes away, just the signal.
Personally I would suspect your modem as #1 suspect.
Factory reset rarely fixes much, I would try re-flashing the phone.
If KDZ flash doesn't fix it maybe try a tot & dll flash using LG Flash Tools with modified megalock.
It definitely looks like a modem issue BUT it can be a your os. I had issues where my modem wouldn't flash from a stock flash on my S4, But manually flashing my modem would SOMETIMES work, I would have to flash the modem a few times usually before it would actually flash.
I had problems before but it was caused by network. Did you tried with different SIM card from other network?
I have the same problem and couldn´t fix yet... Didn´t try to use another SIM card to check if is a network trouble, but it´s driving me crazy to be without connection and a huge battery draining...
Any other ideas?

Just try with other network SIM. I had same problem long time back with Nokia n96, Motorola defy and some other phones. Some of time it helped to set phone only to use 2g network. That was happening the most of time when i used VIP network in Serbia.
Setting only 2g signal helped sometimes but after changing SIM card, problem was solved.
This problem happen to me without reason and after some time i tried same network again, there was no problems.
Probably a different SIM will correct the problem, because after a lot of trial and error changes I realized that the current Network APN (you can reach going on Mobile Networks inside Connections and Networks [translation] in the Settings) was faulty. I deleted the APNs and made a restore. (Delete and Restore are the only options inside Network APNs).
I imagine that changing SIM cards from another carrier will reconfigure the APNs and probably fix the problem.
I´ve tried a different SIM card and didn´t found any troubles, but when I put mine, the problem come back again... So it´s a problem with my carrier. I´ve deleted the APN settings, restart, restore, restart again and didn´t solve. I´ll call them to check if they are experiencing any network issues.
Hi everyone, good morning
I pose this problem ...
I updated my GT-N7100 from the stock version 4.4.2 to 7.1 RR, which is why the phone was no longer lit. The Samsung word appeared looping at its ignition and no reset options worked.
All after the battery suddenly abandoned me!
After the upgrade, unfortunately the mobile network is no longer detected, or rather, the phone does not hook up the signal even if mobile networks are detected (select networks, Vodafone, Tim, Wind, Tre).
If I try to hook my network manually (Tim), the error is the inability to record.
I checked IMEI and is present, and, as mentioned above, networks if you look manually are seen.
I've downgraded to version 4.2.2 to figure out if the problem was about rom, but even with this version the network is not hooked up.
I also tried with other sim, but nothing in fact.
Unfortunately the backup I made did not go well and did not save the files in the EFS folder .... the badge sees us well !!!!!
Do you have any suggestions?
I also tried to reflect the rom Viper, but no change in the network ...
What other tests could I do? Thank you all!
I'm gonna lose my mind.
Last week I did a factory reset. Everything was great for a few days. Then as of Monday, my phone no longer connected to mobile network. (I'm on Visible, which is a Verizon MVNO.)
I tried the same SIM card in another phone, and it worked — but a different SIM card did not work in my phone. So it must be the phone, right?
I looked at About phone > SIM card status:
Network: Visible
Mobile network state: Disconnected
Service state: In service
IMS reg status: Registered
Signal strength: -113 dbm
Network Cell Info Lite app showed the nearest tower and:
SIM state: Ready
Service state: In-Service
I tried resetting network settings and restarting in safe mode, but that didn't help. Visible said to take the phone in to Samsung repair center.
So I did that. They ran a diagnostic, and said everything was fine. They said try factory reset again.
So I factory reset the phone, again, from recovery mode, wiping with cache several times.
After, service was working. Yay!
But then a few hours later, the battery died, and ipon powering back up, I AGAIN no longer have cell service!
Could it be related to adding a work profile? Enabling dev mode?
Any bloody idea what is happening??
I'm loathe to do another factory reset, as it takes me half a day to set up everything again (Work profile authentication, etc.)
Please help save my sanity.
Thanks!

Try playing about with this app, it allows you to force the phone to connect to specific network bands, possible you could force it to reconnect when it drops out
Samsung Band Selection - Apps on Google Play
This app will help you access hidden network settings for forcing band selection
play.google.com
SOLVED!
I popped in a SIM from a different carrier, causing phone to restart, then put back the Visible SIM, forcing phone to re-retrieve settings.
Whew!
Couldve been a CSC issue?

Congrats to you, but my problem didn't solved yet...
@*Detection* i have tried this app many times but didn't worked for me... maybe i have lost my IMEI & device is just showing dummy IMEI though IMEI is same after & before flashing the ROM but when i flashed the IMEI went to NULL in settings then after applying essential fix IMEI came back it also detect the sim but not picking the cellular network only showing the name of network...
