how to change IMEI on dual sim qualcomm devices

Hi!
I have a Xiaomi redmi 2 which have a qualcomm cpu. I lost my IMEI and baseband but I succed to restore the IMEI of the SIM 1 one and his baseband by using EFS professional. But EFS pro can only change the IMEI of the SIM 1 and he isn't able to change the IMEI of the SIM 2. Now, my Xiaomi redmi 2 work as single SIM phone
Can any body help me to restore the IMEI of this SIM 2 ?
I flashed every stable rom bu this was no issue, I flashed also the modemst2 partition of another redmi 2 but it didn't solved my problem. I tryed every app in the Play Store, which may be able to restore the IMEI but all of them are made for MTk devices or doesn't support a dual sim devices. I tried also Xposed IMEI Chager but it is unable to change the IMEi of the SIM 2

Imei and baseband problem

How to find IMEI2 on Redmi note 6 pro?

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.

imei 1 and imei 2 are changing places

on my xiaomi mi 10 when i install for example indian rom my imei numbers stay as they should at 1st and 2nd slot, but when i try another rom like cn rom the imei's are changing places 2nd sim is being 1st and 1st is being 2nd sim.
any clue why?

Question OnePlus 9 convert dual sim 2115 only

I've been trying to convert OnePlus 9 2115 to dual sim for the last few days,At the end of my experiments, dual sim was successful,
, I couldn't enable dual sim in oxgyen os or color os in any way , now i have a question for you , how can i convert 2115 to 2113 , how can i change the model code ?
Even if I flash the European rom inside the phone, the model code never changes.
No matter what rom is in it, the model code is always the same 2115. When European rom is flashed on tmobile phones, the model code changes in android 12. but I could never change the model code of my global phone to europe, if the model code changes, it will be dual sim.
Now what I'm wondering is why does it work in engineering roms while dual sim works in European roms, what is preventing this in european rom?
How does the phone know it's a single sim?
