after change the rom of my lenovo a 850, dual sim the second sim slot not detected no chip and no network please help
i try 3 diffrent official rom on my phone. but also i have the problem for second sim card.
IMEI might be invalid
Try to find out if your IMEI are unknown by your phone.
I had similar issue after I flash a stock ROM on my A850. For some reasons I could not use my two SIM cards as previously. IMEI of both SIM slot could were not identified by my new freshly installed Android. I had to do some engineering tricks by using "Engineer Mode MTK Shortcut" from Google Play and I followed tutorial on Youtube on Invalid IMEI. Lucky enough, my sticker inside my phone was still intact and could set those IMEI digits back on this phone. IMEI is a 15 digits code. Your phone has 2 IMEI.

it has one IMEI . after flashing the phone the imei wasnt known . then i register that with dongle . one slot only be active.
You have to register both slots with their respective IMEI. Was quite easy for me:
1) Install Engineer Mode MTK Shortcut from Google Play
2) Look for some video on Youtube about "Invalid IMEI on MTK Phone". Commands for registering the second IMEI has slightly different parameters than the first one but it works. All detailed in few videos that I cannot post URL but easy to find.
Problem not solved
I also have same problem and the problem is that the phone after rooting it was showing only one sim with invalid imei and the second sim is not being shown at all. It looks like it has become a single sim after rooting. Please help in detecting the second sim.

Imei is rewritten, but phone serial number is changed to Android serial number (not the same as on the back of the phone), dont know if that has anything to do with no sim issue or not.
I wrote correct serial to a file in efs folder, and it showed correctly in the phone settings, but after CM flash phone sn reverted to Android sn.
Really not sure if it is a hw or sw error, tried few 3rd party repair shops, but it seems to me that they know less than I do.

Hi guys my friend bought a cheap very old used mediatek android phone (micromax a064) few days ago. it was getting alot of app not responding errors so we decided to flash stock rom. after that im getting invalid imei error. when I checked imei behind the phone its not clearly visible the paint has came off I can only read it partially . so my questions are
is there any way I can regenerate the IMEI number of the phone?
or is there any bar code reader that can read damaged imei barcode?
and before flashing I was using mtkdroidtool so that I could backup IMEI number but i got buzy with something and in a hurry never clicked on back up button. but I remember that it showed me IMEI number does it store temporary info somewhere on the pc ?
Greetings,
I would like to ask for anybody's help on fixing a dilemma that I can't seem to solve due to how limited my knowledge is.
Colleague messed up his phone very bad, he was trying to "Unlock" his phone through SamsungTool. Here's what happened;
1. Phone is carrier locked.
2. Read a guide that suggests that he should flash a "lower" baseband.
3. Flashed a lower modem file through Odin. Didn't backup EFS. But did take a photo of IMEI and S/N using *#06#.
4. Faced with DRK error. Phone is inaccessible.
5. Rooted the phone to remove DRK error.
6. Phone is now accessible. Used *#06#, IMEI is now 3500000000006, S/N is none.
7. Force flashed IMEI using Samsung Tool. Luckily, he took a photo of the *#06# details.
8. IMEI is now in place but MEID is different, S/N says "None"
Is there in anyway in fixing this?
Hello everyone,
Due to a bootloop, I've reflashed stock ROM then Lineage OS to my phone. However, I was not able to receive any signal from my SIM card with both OS and my IMEI was null (after dialing *#06#).
I have followed a tutorial to repair IMEI with the help of QCN and QFIL. I have disassembled my phone to retrieve an IMEI number (it was written on a sticker next to the battery).
Nevertheless, I have not found the second IMEI for the second SIM slot anywhere on the hardware.
The IMEI number I have found appears to be IMEI 1 and I was able to restore it with QCN. Still, IMEI 1 (now working) works with SIM/SD slot, so if I can now receive signal from the network, I can't use my SD card.
As I don't have any IMEI backup nor the phone's box, is there a way to find this IMEI2 on the hardware?
P.S: repairing IMEI2 with the same number as IMEI 1 does not make it work.
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.
