When I ROOT, I unblock BOOTLOADER, the connection to the network is blocked: /
Bootloader unlocked = connection blocking

Prior to root it you had to unlock the bootloader, the network locked is a different thing.

Did u network unlock before hand?
I solved the problem.
Flashing new firmware must be done with the SIM card (s) in the ports.
Otherwise, during the first telephone connection (not data transmission), the SIM port will be blocked.
It is possible that this is because I changed the CSC codes from branded to XEO.
I will write it again - you upload new firmware, there must be cards / SIM cards in the ports.
I wrote it via Google Translator
I would like to add that when we want to quickly get rid of the PRELOAD state, we need to upload the previous Andorid version 10. This will change the Preload state to Checking.
Hi all,
Same problem, unfortunately not resolved by flashing with the card in place.
Basically after flash (even though I reverted to the original firmware after previous root) the phone can connect to the mobile network.
But after the first call (if the bootloader is unlocked) it looses the connection and says "no SIM Card".
So I cannot root or anything as it results in a loss of phone, messages and mobile data...
Any idea how to prevent this 'SIM lock'?
EDIT:
This now also happens after returning to stock and locking bootloader and oem.
Tried different sim cards, same result...
i'm having the same problem.
Anyone resolved this?
Same problem here.
What worked for me was this:
SIM/Baseband/IMEI errors since Tuesday 17th
I'm getting a problem where everytime I try to call someone or I receive a call, my SIM cards become undetected, the phone crashes after a short time and then doesn't detect SIM cards again, and Samsung or Google backups stop working, and all...

Important bit is not just flashing AP in Odin, but also all the other bits (BL, CP, CSC) from the firmware. I did not need the pit file at all.
Flashing just the AP did not fix the issue but flashing all parts of the firmware helped. Hence I was wondering about the modem...
After flashing completely back to stock, I repeated the rooting process and it's working fine now (using the same firmware AP file but with the boot.img from Magisk).

Hi there,
Recently, I've been having mobile data problems with my s6 duos
I've got an s6 duos from globe, so 1 sim slot is locked to globe and the other sim slot is open line. Recently I've been having problems connecting to mobile data using my smart sim card. In the data service network, the option to choose smart for mobile data is locked/unavailable, so I can only use my globe simcard for mobile data. I've tried using a different sim but no luck.
I was able to use my smart sim for mobile data in the past. Though I have no problem receiving texts or calls with my smart sim
Advice is much appreciated
Thanks
Also, in APN under my smart sim, I get this message
"Unable to view the access point name settings. Access is restricted for the current user profile."

My guess... flash BTU ... latest UK g920F firmware. Its kind of imposible to lock 1 sim and the 2nd sim to be unlocked.
Edit: you may lost warranty after this... and this is only my guess.
Edit2: flash a costom recovery... do a full backup so if something goes wrong you restore everything

Thanks for replying! I've never really done something like that before.. so if you could give me links and let me know what are the risks of flashing?
also my unit was purchased locally in the philippines, will a uk firmware work with it?
In settings search "profile" if the cell phone finds any ,post a screenshot of if... and you find firmware at samfirmware.com... or a guy have posted them in general section uploaded in google drive for better speed download

I had the g920FD... the phone use one EFS for both imeis. I said it cannot be 1 sim lock and 1 seem free. The phone for sure contain something installed from provaider to restrict the sim1. I would flash new version. But as i said 1st ill flash recovery to do full nandroid backup
I have Samsung Galaxy S3 GT-I9300. When the google drive app was downloading from google play, my phone went off due to poor battery. Later when I tried to turn it ON, it has been getting stuck in the boot. So I decided to reinstall my custom ROM. Being busy with my baby, toddler, household chores and job, I gave it to my brother to flash the ROM. After a while, I noticed that my sim was bricked.
It says "Emergency Calls Only", has fake IMEI but working signal.
We did not backup the efs. I tried searching all the methods like modem installation, CSC, baseband verions, IMEI re-write, Kies Upgrade and Initialization, other people's efs restore, etc. But the problem is unchanged. Some of the followed method might have failed for not having proper knowledge like IMEI re-write tool works on specified chipset, etc.
What we noticed is that using different baseband version toggles from having network signal or no signal.
Kies shows more than four firmware versions and no other details like CSC, etc.
How do I clean up all these especially to have SIM working on my phone?
I appreciate you assistance to be brief and clear to understand steps than sending links. Because my time is stress-fully short.
Hi !
There is some confusing info in your post
What do you mean with it has fake IMEI " ? Have you changed it ?
You say that you have a working SIM on certain basebands , is this happening on a custom rom or stock ?
Have you tried to flash a stock firmware as I see that you tried to flash "your custom rom " ?
Cheers !
First of all, thank you for your response and interest to assist.
My mobile's IMEI is shown as 004999010640000 which is not original. Can you help me to change it to correct IMEI suitable for my Samsung S3 GT-i9300 chipset, if that helps in enabling sim to connect to a network? I think changing method only masks the IMEI?
I have tried flashing stock firmware and also Kies Upgrade and Initialization.
I have also changed baseband version installation on stock ROM too. I don't know which baseband is correct to keep.. for my country India or in the country where my mobile is manufactured, incase that's locking sim accessibility? Some baseband bought signal and detected the network operator name, but the message still says "Emergency Calls Only" and is unable to connect to a network.
I presume this problem arose when installing custom ROM from TWRP recovery and it messed up with efs partition?
I had successfully flashed custom ROM many times before without this problem. I think there's some next step to follow to bring back the working sim like I heard of installing modem. I did just try installing modem but same problem as my baseband is already bringing signal.
I had tested my phone from sim unlock app and found out that CSC is locked and it limited specified MCC and MNC numbers. Is this hindering connection to Indian mobile network? Or corrupt efs? Or missed to manually install something?
Bump.
Hi.
My Xperia Z3V (D6708) has a problem to get a network signal.
Originally it works with SIM card but after i flash using a Flashtool with lower version, it does not gone with normal process.
Right after flashing ROM file, it does not process in the fota blah file so i tried to install ROM file with upgraded Flashtool and flashed successfully.
All Rom files copied to my phone normally but i can not attach my phone to network with a NETWORK ACCESS RESTRICTED sign. This sign always turns on notifications. Flashed other version of original rom files but i can see the signs with no network signal. Any different roms have same problem.
SIM card works with other phone and IMEI numbers are all alright.
I think this problem definitely comes from Flashtool with lower version.
How can i solve this problem? If i need i can use QPST, QXDM for changing NV values.
Hi!
My dual-sim P20 (EML-L29)has an issue with sim. When I put (working ) sim to any slot the phone request pin, after I put it the phone starts but the carrier doesnt work. Instead of carrier name I have a cross with no-service/ emergency call only. If I do manual carrier search phone found it, however phone cannot connect to carrier due to "registration error". On the other hand, I put 2 sims simultaneously and one of them connected to carrier.
What I done
wipe cache
factory reset with wipe cache
downgrade from 9.1.0.311 to 9.0.0.280 with HiSuite
The phone shows two serial IMEI. Is it normal? I dont have experience with dual sim phones.
I suspect that the problem is caused by modem. If it is possible to flash modem separately? The bootloader is locked. Any other ideas and advice are appreciated.
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.
