Hello
I just ran into the no SIM detected problem many people already had. This happened after having flashed Pount ROM CM 11, after which I tried to restore my stock ROM backup with no success. I also get signal.
I did some lookup, and it seems most of the time the obvious symptom is the loss of the IMEI.
However my IMEI is fine. My baseband is also correct. I tried restoring the whole "efs" folder which I had backed up a few months ago, but still no go.
Which other options do I have? I'd gladly read some other thread but I could not find any other similar situation - maybe because most of the time the IMEI is loss.
Can I get some help? Thanks!

I'll just answer myself as I kept on investigating and it may help somebody observing the same symptoms: the SIM card was simply dead. Yay, my I9100 is back on track :victory:
Hi guys,
A month ago my phone got stuck on Samsung's bootscreen (I was using CM10.2). I tried to restore a nandroid backup but the recovery wasn't able to mount /data, so I had to restore my phone via odin flashing official firmware. Then /efs was corrupted so I lost my IMEI (0049...), therefore I wasn't able to connect to the mobile network (no calls, no data connection...) and I hadn't a backup for that (yes, really dumb). Yesterday I took it to a repair service from a mobile store (definitely not the official one) and they restored my old IMEI number, as I can check it comparing the one behind my battery and the one shown dialing *#06#. But it still doesn't connect to the network, only emergency calls. When I try to call, it displays a message that says that it isn't registered in the network, and if try to register it manually, a toast notification displays saying that it's registered but another one in the notification bar says that the network it's not available.
Things that I've already done without success:
- Back up and restore /efs (kTool).
- Flash CM10.2.
- Flash official firmware.
- Tried with other's SIM (mine works fine in other phones).
Any thoughts? clues? anything that cross your minds? I need to bring my S3 back to life and I don't really know where to begin the research (I googled like hell, though).
I'll appreciate any contribution (even if it's just a description of how network connecting works at low level, codes to check, etc),
Thank you (and please forgive my poor english).
Try patched modern and kernel, if that doesn't work then take it back to your repair store.

Thank you for the quick response, I'll give it a try right now!
EDIT: It worked, thank you!!
I'll explain for others. I had CM10.2 before repairing it following the instructions of boomboomer. I've downloaded the firmware I9300XXUGMK6 from here and flashed it with Odin v3.04. After this, I had to get root again and flash cwm recovery (CF-Root-SGS3-v6.4 with Odin). Then just flashed the two files listed on this post. Now it works again.
Well as the title says.
Just rebooted my s2 and now when I try to do anything it says "insert sim card to access network" imei is fine serials fine and even shows signal bars but soon as try to make a call to drop signal and network completely....
have restored efs folder and even dne a repair.
changed base bands
reflashed new rom
tried different sims(and networks)
and still nothing
Odd that it happened after weeks of being fine and then just did a reboot and then this all happened
any ideas folks as to next move?
please someone must have an idea or two. to offer!
Well looks like I have fixed the issue after many hours of frustration..
Still have no idea what happened to cause issue in first place..
What I did was refresh my original backup
flash original STOCK rom via odin and this seemed to have fixed it. Are there any friggin better loctaion for these files as took 8 hrs to down load the damn thing!?
now re rooted, flash custom rom, flashed custom kernel of choice and than restored back up
everything seems ok(though my imei is incorrect now as says 004999010xxxxxx ,but am concerned it will happen again. Had flashed a modem several days before and updated a few apps . but at time of the issue occuring was just clearing caches then a reboot..
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...

That was a guy who work in service, I don't have his contact anymore... but that's what he told me...write that chip in motherboard and get new imei number...it was very expensive, almost a half price of the phone...

I know the topic is old... But I have the same phone and the same network error. Has anyone here managed to solve it?
Hey everyone, I'm hoping someone is able to point me in the right direction.
I have an S9 Plus with TWRP installed and DevBase v5.9 as the ROM. I have made two backups using TWRP, one from when I first got the phone and a more recent one (within the last week).
When I first got the phone I removed a lot of the bloatware that came with it (Samsung stuff and other junk). After using the phone for a while I realized I needed to keep a couple of the Samsung apps, mostly Samsung Themes and Galaxy Apps (to keep other Samsung Apps up to date). This is where the problems first began.
I restored the backup I made when I first got the phone because I didn't remove any of the bloatware. The backup restored without any problems, I started updating apps, getting it back to the way I had it and noticed I didn't have any reception. I tried to make a phone call and it displayed an error "Not registered on network". I thought something went wrong during the restore, so I tried to restore the phone with the more recent backup I had. That, too, gave me the same message. I checked the IMEI number it was displaying 0000000000000/01. Definitely not my IMEI.
I tried my SIM card in another phone and it worked without any problem. I tried my partners SIM card in my phone and it displayed the same 0000000000000/01 IMEI. I downloaded the latest stock firmware for the phone in an attempt to try and get it back to normal, however, even on stock android it displays 0000000000000/01 IMEI.
So I'm in a sticky situation at the moment. Is there any way to recover from this problem?
