After updating firmware official, device shows no signal. Sim car is detected but unable to manually search for a network. I flash 2 custom roms, no change, went back to ICS official, still no change. Flashed 4.2.2 update official and still no change.
I tried different sim cards and still no service. Sim card works in other devices. Can anyone assist me please?

I flashed my Xperia T (LT30P) today to a firmware version of ICS 4.0.4 after updating software the other day (5/31) to jellybean 4.1.2 Now, my phone isn't picking up data nor showing up as 4G LTE. The firmware I used was 7.0.A.1.303 Vodafone. I have tried a factory restore with no success. I live in America and the firmware was UK if that makes a difference. I visited at&t today to resolve the issue. They told me that the network is functioning fine and tried my sim card in a different phone, which worked fine. So, is there anything I can do? Thanks in advance for helping.
It does make a difference if you used UK firmware on an American phone. Since the UK communicates on a different frequency than the US, the two are not compatible. The only option would most likely be to reflash your phone using a different ROM, or flash it back to stock.
The provider specific SIM menu is available, but the tablet shows no signal. Even when it shows one, the signal disappears the moment I try to make a call or am about to receive one. The caller can still hear ringing while the tablet lists the call as missed call.
My father's Galaxy Tab 2 7" automatically tried updating through wifi but failed (I presume), and the SIM functions stopped working.
After many attempts I updated it through OTA to the latest firmware, shown as PDA:NA3 / PHONE:LK1 / CSC:NB1 (INU) in Kies, and the Android version was listed as 4.1.2., but the problem persisted.
I tried to wipe cache. It didn't sort the problem.
Then I Installed CWM 6.0.7 and Cyanogenmod 10.1 (JB 4.2.2) using this tutorial: wiki.cyanogenmod.org/w/Install_CM_for_p3100
Still it can't make or receive calls.
Baseband version is listed as p3100ddclk1
What to do?
Is this a hardware or firmware problem?
Hey brother,
Even I am facing the same order on my tab but in a different way. I can recieve signal for the carrier Tata Docomo but other carrier are showing any sign of life
But sometimes while on tata docomo , I lost signals while using data or when I got a call. And one more thing, I was on a trip to a hill station and there I was getting signals from Vodafone perfectly (my main service provider). But when I came back from there I ain't receiving any peice of signals from vodafone and Docomo is working as usual with few network losses during the day.
PS.- I ain't received any solution yet, still sticking up with that problem.
PPS.- The tab I brought is in used condition with the fact that the tab has that problem in it. (I need not to pay much lol)
Btw I think if we can flash new firmware (official) with odin with modem file, It may sokve our problem. TRY FLASHING FIRMWARE, I cant as I am low on speed

I am not sure about the Model file alone but you can download whole firmware from sammobile.com, they have firmware of all Samsung devices region wise, just login to enjoy better speed.
Hope this helps.

i already download the firmware for Malaysia and how to get the modem file from it? Should I extract it and search in?
Hello, I can't connect to my local mobile network anymore.
So I can't call or receive phone calls.
I am in Latvia, Baltic region.
My imei is legit and working, so is my phone number.
When I search for my mobile network it finds it -LV TELE2, easy, but when I attempt to connect to it, it shows it 'can't connect to this network try later', when of course the network is working properly for other phones., and it is the network that worked before.
I happened after I flashed a custom lineage rom. It was the right rom for my device,
and I flashed it in correct order and all worked except mobile networks.
I thought using odin to flash back the stock rom will fix it, but it didn't.
Now I am back to stock 7.0 , flashed csc SEB version for my region.
Now in mobile networks there is only Lte/2g/3g options, why there is no gsm or vcdma mobile service?
I believe my provider is gsm, so how to restore it so I could call again?
It shows no service in the drawer, and can't connect to my carrier.
Any help is greatly appreciated, thank you ^_^)/
Had same problem after my motherboard was changed in some mobile repair shop and old imei and stuff copied from old motherboard. After flashing stock 7.0 with ODIN, I had same problem. Luckily repair guy added some certs back free of charge. Something to do with not being official Samsung repair place and not having right kind of tool.

Thank you for your info. Then it must be possible to fix it with the right tools even at home! I am sure there must be someone who knows how to do it and can help me, and many others with the same problem.
When you tap *#0011# imei status is OK or NG?
Hello, I typed *#0011# and yes imei status is ok, more info - rat=gsm (2g), band=pgsm900 and reg status is = not registered.
So this couldn't be an imei problem, could it?
During this time, I tried many roms, nougat and marshmallow, official and custom, but none has fixed it yet.
I was thinking, flashing original galaxy s6 lollipop rom will definitely do the trick,
because I remember I had a similar problem with my old galaxy s plus phone,
it was impossible to connect to any mobile network on any rom,
until I flashed the oldest stock rom for the device.
But the problem is, I can't find a working download for a custom lollipop rom, they are extinct it seems,
and the official lollipop rom can't be flashed with odin, obviously, because I have a higher fw already.
Official lollipop would be the best and would show if the problem is software related for once and for all,
but how to install it when knox and all kinds of binaries doesn't allow me to flash it with odin?
Is there another way to do it?
No need for this anymore, never solved the issue.
I sold the phone.
Thanks anyways ^-^)/
Hello guys!
I have a SM-G955FD. Bought it two months ago and was working perfectly fine till 2 days ago when all of sudden it cannot connect or register on a network. I had 2 sims in it and neither could connect to any network. Instead, it displays this on the status bar instead of the usual bars.
The sim cards work perfectly fine with other phones. The device detects both sim cards.
I have to checked to see if it's an imei error but it is present and it is not blacklisted either.
I factory reset it and it didn't fix it. I reflashed the firmware and it didn't work either.
Also, I cannot dial *#*#4636#*#* either. It says mobile network is unavailable.
Any suggestions?
Weird, did you get this working?
Can you get to the diagnostic menu?

Not yet. Reflashed the firmware again with no results.
Yeah, I can to the menu. What should I do there?
Unknown imei status.
Hello,
This happened to me yesterday and yes I freaked out. It turns out in my case even after flashing other roms I was still having the same problem where sims were not being detected and imei was unknown status. My fix was reflashing baseband. I used latest baseband from the renovate ice website. Hope this may work for you.

I am unable to post links.
Please visit Renovate Ice website, go to firmware and choose the 1st OPTION 'CRI5', download and flash via twrp.
Good luck.
I am having same problem on my G9554U1, have tried flashing official firmware latest and also last update multiple times but still no network, was fine before but don't know whats the problem now, if anyone can guide would be very thankful
I recently bought a used Samsung Galaxy S10 (SM-G973F).
At first glance the phone was in excelent shape. The SIM Card was connecting to the mobile network, and calls, internet connection, etc was OK.
But then, I found out that the phone had been rooted. Probably, by the seller. In pannic, I rushed to unroot flashing the stock Rom.
Here what I did:
1- Forgot to check my precisly CSC code and assumed ZTA (cause I'm from Brazil, and the phone is from carrier "Claro")
2- Downloaded the stock rom using Frija
3- Using Odin 3.14.1 flashed the device.
The previous rooted system was on Android 10 and One UI 2.5. With this new rom went to Android 11 and One UI 3.0.
The problem:
The phone recognizes the SIM Card. But it simply doesn't connect to the network. When I try to make a call it says: " not registered on network"
The phone DO recgonizes the SIM Card. On the SIM Card Manager shows my carrier name (Vivo) and my phone number. Also, the SIM app is showing on the app list.
Things I tried:
Rebooting the phone
Changin the SIM Slot
Testing the SIM on another device to ensure it was working
Checked if the IMEI wasn't missing/undefined. It is not, the IMEI appears to be untouched
Checked if the IMEI had been blacklisted. It's not.
Flashed SEVERAL different stock ROMS with different CSC (ZTO, ZTA, ZVV)
Try to manually select the network. This also throws an error saying "error while searching for network"
I'm really desperate and don't know what to do anymore.
No one have a clue either? :C

How to Fix 'Not Registered on Network' on Android
Here is how to fix 'Not Registered On Network' error on Android. Mostly error occurs on Samsung phones, but this solution works for all android phones.
www.android-recovery.net
Wow,
This is exactly like my S10 right now.
At first, all is good, the signal was great, all working well, except cant connect to samsung pass and samsung health because it was root.
then i brought to sellular shop service, to flash the phone.
Then, “not registered to network” happened. The signal ok, the phone able to read dual simcard, but “emergency call only” and if i try to search network manually, “error while searching for network”
And the sellular shop service have no idea how to fix after they reflashed and try to fix it for several days.
Have you found any solution to fix your pho?
pls advice…

So, were you able to find a solution for this problem? I also bought a Note 9 N960F/DS recently and found out it was actually a N960N model that was changed to N960F/DS. So I did exactly what you did, I flashed the original stock rom, N960N, but now phone will not connect to network. I also did hard reset, reflash other stock roms, nothing changed. Anybody with insight should please give us some pointers.
