ZTE A7s 2020 (A7020) IMEI issue. - General Questions and Answers

Greetings!
I have the phone and after flashing IMEI dropped to some random one (111111111111119 on both IMEI1 and IMEI2). I wrote the proper ones using MOBILETESTER but the phone still shows no signal. What can I do? Can it be IMEI SV or SN problem, as IDK what originally was there and no backup of course.

OK, so I edited the SN number, now it shows the proper one in *#06#, however, it cannot still see the SIM. Now I don't know what to do. Could anyone help me?

BUMP. One more and I'm sadly done with this with no solution…

NOTE:
MABY THE PROBLEM FROM THE IMEI NUMBER, BECAUSE I GOT IT WRONG , IT IS LIKE IN THE ATTACHMENT.

Yep, a borked imei number will not allow you to connect to your cellular network...
I'm guessing that your efs folder wasn't backed up... you can try this...http://forum.xda-developers.com/showthread.php?t=881162
I haven't tried this but good luck.
thank you brassguy...
but does this work for infuse 4G ?
In addition, I read that we can change the IMEI number using the ADB, or is there another way to do this?
Also, what about the GSII_repair app, can I use it for my phone (infuse 4G)?
i had this problem last night where i flashed a rom. i return it to stock and imei showed up.
was having a imei" unknown error" and i backed up now on my computer.
ps ebay sales unlock service for 0.99$ if you didn't buy the code and just hacked it with hex or whatever
mine is already unlocked and it's permanent
i do travel over seas alot
But i returned mine to stock many times but the imei number still like this.
I did no get you in the third line???

No one have ever faced or seen this problem with someone and solved??

Huawei e5776 imei

I have a very weird problem with this device.
Recently bought one off another person. I tried to flash it but the flash code is wrong.
After reading that the flash code should not be wrong and derived from the imei, i realize it is highly possble that the imei on the back may not be the imei of the mobo itself. Would like to ask if anyone knows how to check the imei of the device via any software?

[Q] Cloned phone same phone operator ?

Hi,
To revive my dead phone, I cloned another one of the same model. I tried for a week all tools and tricks on planet earth but nothing works to get my IMEI back because I don't have a backup of the original IMEI. I'm just asking if I can use my phone on the same phone operator as the owner of the original IMEI. I'm afraid they block this IMEI for both of us if they find that two phones are using the same IMEI at the same time.
If someone is in this same situation please help me.
Thanks.

Seems to be a similar issue like here: [Q]Null Imei, Baseband Unknown N7105 by Emprt.
With a "broken" EFS partition.
Check this thread: Baseband Unknown and IMEI Null NOW WORKING by karlonicolas.
Maybe this will work in your case too.
Sometimes reflashing the modem/baseband can help to get back the correct IMEI.
And for the next time, please backup your EFS partition like described here: [WARNING! + GUIDE] Backup and Restore IMEI / NV Data Procedure for GT-I9305 by lyriquidperfection.
Good luck !
Thread closed. Thank you!

I found the fix for my null IMEI here on XDA

Thanks to this post: http://forum.xda-developers.com/s7-edge/how-to/guide-how-to-fix-check-drk-imei-issues-t3379516
I had soft bricked my s7 a while back. How I managed that I can't remember except that I reached a point where the IMEI was null which meant I couldn't connect to my carrier.
And then I found the above mentioned post. My phone is now functional again, with its proper IMEI. I tested it with my SIM card and made a successful call.
I thought I would mention this in case someone else is having IMEI woes and this might be of help.
