Good day guys.
I have a problem that I think is very common, however I haven't found a solution yet. I recently update my S6 edge (925I - latam) via odin to Nougat, everything was cool but I can't do or receive both calls or sms. I have cellular signal, however there is not registered with the network carrier.
I already flash modem.bin from older firmwares and do not work. Sometimes I loose cellular connection or stay the same, with signal but not registered. I tried other possible solutions like airplane mode and reboot, flashing roms, connect only via 2G or 3G, nothing have worked. My sim is not corrupted and the imei is just fine, without report or related.
I hope you can help me. Thank you very much.

Same issue for me.
Tried:
OTA update
Odin update - installing new stock firmware (with different software version)
Factory reset
Installing TWRP + LinageOS beta
Replacing the sim slot in a service
Nothing worked. Anybody?
Look in settings > status
Do you guys have an IMEI?
This happend to me 2-3 times last 30 days... sometimes I have signal but not registred on network, sometimes there's even no signal, etc...
I also tried several things to resolve the problem...flashing modem, reset dialer, changing network mode, enabling airpalne mode, another SIM card, etc... For the 1st time, flashing modem helped... but 2 days ago when this happened again flashing modem did not help...then I tried changing network mode and I got signal again... last night it also lost signal and today I changed network mode to 4g/3g/2g auto and it got signal again, then switched back to 2g and it's fine till now...
Hope this will not repeat....if does, coulb be very annoying thing...

Bro, download some older firmware from the one you have from sammobile and exctract it...there you'll find modem.bin
At last, I couldn't fix my s6...so I sold it...then the guy who bought it needed to write some chip to motherboard and he got it working again...

hi guys, just about 2 days ago i rooted my phone. problem is after rooting my phone can't seem to get a 3G signal anymore. only GPRS which is so slow! need help tried reflashing with a stock ICS ROM and still no go.
EDIT: here are the things i did before i noticed the disappearance of 3G
1. downloaded recovery and kernel from tegrak's website.
2. booted into download mode and flashed the recovery.tar file
3. booted to recovery mode and flashed the .zip file
4. installed Tegrak Kernel & Superuser from Play Store
*this is when i noticed that i can only get GPRS/1x signal
what i did after was kept flashing a stock ICS ROM. nothing happened to fix the 3G problem.
searched the forums and none of the method works. tried reflashing stock ROM still a no go.

already did sir, still no 3G signal. i'm 200% sure my area has 3G.. it even reaches 3.5G on my other phones.
okay.. just noticed minutes ago that my other phones are getting up to 4G signals too. and my Galaxy Note can't even get to 4G? its really stuck at GRPS speeds. the root must've messed up something because this is my 3rd reflash of a stock ICS ROM and still stuck with a G signal when data network is turned on.
EDIT: been lurking around xda-developers forums now, even tried other websites... is it possible that a kernel flash could change the radio of the device? reflashing for the 5th time did not do anything for me. after 5 tries (i know, that's too many to figure it out that it doesn't work), i've given up. if anyone has a solution to this problem please message me.
ok guys after a few days of testing. i finally figured it out.
for some very odd reason, this particular sim of mine says "network type: GPRS"
i tried different sim cards of the same carrier (i repeat, the same carriers) and it says "network type: UMTS"
even tried different sim cards from other networks and it says "network type: HSDPA"
so that is very odd. did flashing ruin something on this simcard? i can't really pin point?
anyway for me this problem is solved. i'm getting another sim card hehe. hello again 3G/4G!
EDIT: I FOUND A SOLUTION! its not the simcard, its the band setting! i just switched from GSM to WCDMA and it worked for that sim! there is a secret SKT Telecom menu for the Korean android phones that lets you change the band.ΓΌ
Hello guys,
I have a severe problem with my SGS2.
I was using it as always when suddenly my signal strenght dropped down to 1 bar and since then it's changing between 1 bar and "no service".
I have been running on CM10 Nightly 20120910, thus I thought I'd try another modem. Flashed XXLQ6, nothing changed.
Then I flashed the 20120908 nightly - no change
flashed CM9.1 with XXLX/XXLW modem - no change
reflashed CWM Kernel - no change
I tried using another Sim-Card which operates in another network - no change, still only 4% signal strenght (looked up using Network Signal Info)
The I tried using my current Sim-Card in another mobile phone, and there it worked flawlessly.
WLAN is still working, but no GSM/UMTS. Even if I have 2 connection bars for some seconds, I still have no internet connection via UMTS during that time.
Anybody got an idea?
Greetings, Alucard2050

I'm facing the same issue. Did you solve it?
If it happened suddenly and the problem persists in other phones, than it's your network operator cell.

The problem doesn't persist in other phone. I've tried the SIM in two other phones and it works perfectly.
Also tried another SIM(which works on some other phone) but don't work on mine.

Hi!
Since you are new here, it may be the best time for you to read the forum rules not that you've done something wrong but just to inform you about it
Here's the list of modem that you can flash http://forum.xda-developers.com/showthread.php?t=1131950, it comes along with a guide..
Since everything you mentioned failed, i suggest you flash back to stock firmware and do a factory reset it might just do the job..
i hope this helped you, cheers!

Upon your insistence, I flashed the official stock again, did a factory reset. Still facing the issue. Flashed two different modems again. Still no luck.
Restored by original EFS, no luck. Fixed RW of EFS folder. No luck. Still the same issue.
Please help.

Sorry I didn't read
If you've already full wipe'd your phone and then installed a stock firmware and the issue doesn't solve yet, it may be a hardware-related problem, also because you said that another SIM, working on other phones, doesn't work on your S2.
Try another full wipe and install a different firmware, and if still not, I don't know...

Hey guys!
I'm currently getting the "not registered on network error". I have tried any; if not all threads on this issue to no prevail! It started when i flashed my phone to a deodexed version of the stock firmware for my phone.
What i have tried;
Used my simcard in other phone (Works fine)
*#06# brings up the same IMEI string as the one underneath battery
Using another simcard in my phone doesn't work
Used Kies Emergency Recovery to flash my phone back to complete factory reset
The strange thing is, i then thought after my efforts, i've had a hardware failure. But when i scan for my local networks, i see them just fine. Which would presume the antenna is operational. *see attatchment - Screenshot_2015-01-09-02-30-32.png*

Thanks for the reply.
I think it's on it's way out. The phone is touching 3-4 years old now. One of the first to receive the phone. It seems to be a power issue. I did the above solution yesterday evening which didn't work. However, the phone IS currently working perfectly above 45% battery. Have you ever come accross this issue before?
Is the battery swollen? Try another battery.

You probably need to search a better device. I have a similar problem with my P714, and it gets worse every day - it began the way you describe, and after a while, restarting (or using apps that do it, which is basically the same) stopped helping. I'm about to get rid of this device as it doesn't supply the most basic functionality. BTW I replaced 3 ROMs since this problem began without luck.

It can be rom related but if you don't flash with kdz zip flashes will usually flash just kern and rom. Want me to cook a flashable zip with modem? Tell me if you run kitkat or jellybean.

I've installed the official Nougat update from Elephone using the SP flash tool. Before the update, everything on the phone was working.
After the update, the phone boots Android 7 fine, but no SIM cards are recognised.
I've tried entering Engineer Mode through the phone app to reset the IMEI (I know what they are) but the 'Connectivity' page in Engineer Mode doesn't list phone radios, only FM, Bluetooth, NFC and WiFi.
So I rooted the phone and tried entering AT commands through a terminal. But the folder /dev/radios is empty.
It's like my phone has no... well, no phone. I guess the driver is broken somehow.
Does anyone have any tips on how to proceed?

Well, there's one who didn't read the question. This is not about restoring the IMEIs.
Alright. I know flashing nougat might break the radios and also IMEI. This includes not detecting simcards. I had this problem myself.....
I have the same problem, or similar .
I can sometimes send and recieve text messages and sometimes i can call. Data traffic seems to work ok.
Right now as soon as i try to make a call i lose connection to the mobile network.
Theres a simple fix, reflash 6.0, then do format all + download android 7, imei wont be restored, but both sims will be recognized and work normally

that seems like a hardware issue, i think theres a few cheap speakers and you could try to fix urself on ali express theres speaker at around 10$ it ahould be farelly easy to replace it
I've had this same problem, but only after replacing my screen due to damage. Ever since then, it'll see the sim but wont connect to my network.
