Hi guys,
Here is the deal:
I've flashed my Core Duos (i8262b) with the stock firmware found on Sammobile.
After that, my phone doesn't make any calls or data connections...
I've tested my sim cards on another phone, and everything works.
I'm not so raw in flashing phones, but I'm not a specialist...
I've found that the IMEI of the system (when you call *#06#) is different of the physical one (found behind the battery).
What should I do?
Thanks in advance...

Hello dear ones, I'm lost and I need your help.
I've bought a used SM-g920f, knox x0. It worked flawlessly. Until the first evening when in the middle of a phone call the phone app crashed. After resetting the phone it was still unable to connect to network. I have noticed that baseband/IMEI were set to unknown and so it could not read my sim card.
First I have tried the obvious - upgrading from lollipop to marshmallow. It went easy but did not help. Neither did help resenting to factory settings.
I have rooted and installed twrp recovery adb and stuff.
After almost two days playing with it, I seem to be out of options.
What I tried:
Flashing Different roms - stock and non-stock. (G920FXXS3DPB2_G920FXEU3DPB1_G920FXXS3DPB3_HOME, G920FXXS3DPB2_G920FOXX3DPB2_G920FXXS3DPB3_HOME, Pure-Stock.ExtraLiteROM_XXU3DPCA.DEODEX-v5.5.by.ambasadi, XtreStoLite-ROM-3.0-Final-DPCA) - I do not know the country of origin of this device. (the back is from testing unit), is there some way to know correct original stock ROM ?
Flashing Different modems - (G920FXXS3DPB1_Modem_TWRP, G920FXXU3DPB6_Modem_TWRP, G920FXXU3ZPA1_Modem_TWRP)
Checked sim card in another phone/different card in this phone - if sim card would be invalid, would I still get missing baseband?
Xposed Imei Changer - it did change IMEI. But that's it. Baseband still missing.
*#0011# and other *# stuff..
And I have wiped /efs (it did generate new nv_data. Guess now even broken IMEI would make ma happy)
Any ideas ?
How can I know what can be wrong? /efs partition? wrong firmware combination? hardware issue?
In Samsung Phone Info I get empty on Modem Board, Hardware Revision,Samsung Serial Number,Baseband Version.
Than you for any help or idea!
tried smart Switch emergency reinitialization?
Just to be sure, knox is triped now?
Ok, Ladies and Gentleman I need some deep thought processing here for some help with a Motorola Nexus 6. In brief here is what the problem is, a while back when flashing Pure Nexus rom, I experienced a loss of my IMEI. I can restore my IMEI but if and when I do, I lose any 4g and LTE connectivity. The phone functions in 3g with data and phone etc... just slow as molasses but if I restore my IMEI to the one that doesn't show up my IMEI correctly I get back LTE/4g and all works fine also. I've tried going all the way back to the original firmware which was saved to computer and restoring it. Same thing, I have IMEI but no LTE/4g. restore bad efs and get LTE/4g back. I've tried going through all the factory firmware's and flashing by ADB and or TWRP and nothing firmware wise will allow me to restore the IMEI and have LTE/4g signal. If I restore the bad efs and get OOOOOOOO for IMEI when using the *#06# on any firmware version, I regain LTE/4g functioning! I am using Pure Nexus 7.1 now and can still see the 00000000 as a IMEI, if I restore my efs and get IMEI back showing correctly, no LTE/4g signal! My phone can only function as it should as long as the IMEI doesn't show correctly! I have tried just flashing base bands and other segments of any rom and still the problem persist! I have even tried restoring an EFS from another nexus 6 and still no help. It's not the sims because I've tried AT&T sims and Verizon sims from other phones and it does the same thing! I've tried flashing with a sims in the phone and without. Any ideas??? It's like somehow a correlating segment of a file is not being recognized when the correct IMEI is present, like some thing some where in the efs, IMEI, and radio are not taking to each other so to speak, unless it shows the zero's! Brain waves come on and help me out here!

Greetings and welcome to assist. Have you tried asking in the pure nexus thread to see if anyone else has had this issue ? I have seen it before when flashing aosp/cm based roms but the fix is usually different each time

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.
Good morning XDA,
I'm in desperate needing help, sorry but English is not my first language.
My brother bought a S7 G930F - Exynos that was GSM locked with one company here in Brazil, so he paid a guy to unlock it.
After getting the phone back I notice that the phone now shows G930FD, when I use *#06# to see the IMEI, shows two number, as if it was Dual SIM and both numbers are different that what is written in the back of the phone and the box and the rom seem to be 6.01 but with a lot of programs pre-installed.
So I downloaded the newest ZTO stock rom from SamMobile and flashed, now the phone is on 7.0 but can't connect to the network and still show the tow differents imei numbers.
Any tips or guidance and how can I Solve this?
Thanks, TggB!

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.
