Unlocked and Rooted but cannot change the IMEI number - Xiaomi Mi Max 3 Questions & Answers

HI,
Dose anyone know how to edit the IMEI number for the Xiaomi Mi Max 3?
I searched through all the web but known methods like emptying modemst1, modemst2, fsg and uploading modified xqcn doesn't work at all. IMEI remain as original.

Changing your IMEI is illegal.

I don't live in a Nanny or Police State. In my country this is NOT illegal and i'm also the registered owner of this second IMEI number.

[Q] No network Service / No Serial / IMEI OK

Hi!
Problems:
1) Serial is 000000000000000, although IMEI and IMEI/SV is ok.
2) Out of service network state, although network is detectable.
Solution:
Ariza Patch.
I know I've given the solution, but everytime I have to reinstall a ROM I have to do this over and over again which bothers me, besides having a serial number is better than 000000000.
The thing that caused this was a google app named swapper. I believe it stored the swap file on the partition of the EFS.
The phone's EFS was fixed by some technician, but unfortunately the serial was not.
No, I do not have a backup of EFS to restore. I only figured that out after this happened.
Other apps used to diagnose:
Check FUS - it says on "Product Code" as "Not Active"
CSC Select - played with a bunch of CSC codes to change, still no luck.
Galaxsim - shows my real serial number but phone is already unlocked.
Any suggestions would really be helpful aside from sending it back to Samsung Service Center and restoring a backed up EFS which I apparently don't have.
Thank you!
Ive this problem too

LG G3 LS990 EFS ****ed up. Trying to use EFS pro to get back. Unknown IMEI !!!!

I dont know my IMEI number, is it the MEID HEX? When I enter this into the IMEI converter it acts like its missing a digit. I have 15 characters in my MEID HEX.

[help] network problem - imei Matter - imei NG

Hi
So I bought this phone used.
I put sim card .. the phone shows the Carrier, even shows the APN settings . But I can't make calls (emergency calls only)
The imie of the device found on back is For Factory Unlocked 928A and I contacted ATT and confirm it's unlocked.
The Problem is : when you dial *# 06 # the phone shows a different imei number. And this particular number when looked up doesn't belong to any device on Earth. Using imei checker. And when going to service mode it shows imei: NG
So.
The first step on solution is to restore the original imei number that belongs to the device . That's logic right ?
How can I?
What about efs partition ?
I am on latest Nougat. Can't downgrade to 5.1.1 to root and try to change imei or restore efs
Trying downgrade in Odin give FAIL lol
What to do ? Excuse my English.

*ISSUE* How to restore IMEI (SM-G532G) Galaxy J2 Prime

Hi. I tried to change my IMEI number using the Chamelephon app. It did work, but it didn't turn out great. Network functions are okay, but it needs constant network operator scan as soon as I turn on airplane mode or restart my phone. The IMEI number became random numbers and symbols.
IMEI 1: >8<4=<:7?7<6?:2
IMEI 2: 9><398?64><6086
EFS is fine. Only IMEI has a defect.
I realized that Chamelephon should only be used on MTK (chinese or cloned) devices. Now I can't seem to find a way to get it back. Can someone teach me how, and do I need to get any Samsung Tool Pro type of things? If yes, how do I get started? (btw I want to do this for free)

Zero IMEI number.

It is possible to enter the IMEI number into the device?I changed the software and the number disappeared and I do not have a persistent and EFS backup. Can I upload a QCN file? But where to find the file because when it reads mine by the QFil program, it is damaged
