WARNINGS:

- Possible risk of data loss ! Backup your files and contents !
- NO dongle and NO box is required.
- NEVER try to flash in "format all" mode ! Otherwise, you will LOSE all secure and identifying infos for your device. Like IMEI.

- Keep your backup files safe and secure ! If you can, encrypt them.
- Never try to share your backups or your security and privacy will be compromised.
- USE AT YOUR OWN RISK. I AM NOT RESPONSIBLE FOR YOUR ACTIONS.


As we all know, we can not restore the IMEI for SLOT1.
But as we are already tired of seeing, every day are several people with this same problem.
So we are opening this thread to discuss possibilities for how to recover the IMEI for SLOT1 too.
If you have any idea or discovered something, share with us so we can discover new possibilities, methods and solutions.


Possible Method # 1:​

This method was released by HALABTECH. This method was tested by @jasmin811 ♥️
The idea is simple. Flash the ENGINEERING ROM, write the IMEI in META MODE and then flash the CUSTOM ROM: PixelPlusUI or PixelExperience.
Steps:
#1. Flash the ENGINEERING ROM:
#2. Enter in META MODE and write the IMEI for both slots (SLOT1 and SLOT2):
#3. Backup the partition NVDATA:
#4. Flash the CUSTOM ROM:
PixelPlusUI: https://forum.xda-developers.com/t/...ui-for-redmi-note-9-merlin-merlinnfc.4254885/
PixelExperience: https://forum.xda-developers.com/t/...-redmi-note-9-redmi-10x-4g-aosp-beta.4236913/
#5. Restore the partition NVDATA.
#6. Flash the version AL2522-Merlin-V039-Q-0513 of the partition MD1IMG:
#7. Boot to the system and then reboot.
Done.

Hi guys,
This method works pretty well with custom rom pixel experience for note9 merlin.
I'm still looking a way to get it work with stock roms.
For this method we need one file to make it work properly,it calls 'patched md1img'.
I will make later more details about it how it is working and I will upload this file later.

You can write both imei using the engineering rom.
But you can't use both imei on stock rom.
If you want to use both imei, you need to read carefully and follow the guide.
Both imei will work only in the custom rom: PixelPlusUI or PixelExperience.
Good luck

Anyone know if i can run the meta tool via VMWare windows? or if theres a osx version of it?

Ive got the rom installed via flash_all, screen goes black (assuming powered off) but it keeps coming up with a connect to windows or mac that vm does with usb connections and the meta tool cant connect

update: fixed the constant connections although the meta tool still cant see it, installed the unsigned the drivers but still nothing connecting. Any thoughts?

Seems to be able to see it in device manager
