IMEI loss due to Android 11 Redmi Note (Merlin) update. - Redmi Note 9 Questions & Answers

Hello, I had a problem with my Redmi Note 9, the IMEI disappeared after the Android 11 update. Does anyone have an efs backup so I can restore?

Efs does not contain imei and you can't share IMEI between different devices or you will brick your device.

What is the best method for me to recover my IMEI? I thought that if I got a backup of the same device as mine I could restore by twrp.

Flash engineering rom, enter in meta mode, rewrite IMEI 2 and keep IMEI 1 as null.
Backup NVDATA, flash wanted rom and then restore NVDATA back.

Hello, the following is my device (Redmi Note 9, Merlin) the IMEI disappeared after the V12.0.1.0 update and until today it has no IMEI. And look that the latest version is in V12.5.4.0 and no solution. A guy I met on the internet forced the bootloader to unlock (I don't know how he did it) and fixed the IMEI problem, but V12.5.3.0 which was the version I was on, was full of bugs (Storage in " others" filling by itself, an error of not connecting to Google servers, it was not possible to use the play store). Because of that I decided to install a custom ROM (Pixel Experience 12.1) the ROM is perfect, no bugs, normal storage, accessing the normal Play Store, I would like to stay in it only with the IMEI working. But in this ROM change the IMEI disappeared again. I would like to know as much information as possible so that I can solve this, like a step by step of the whole procedure, I would be very grateful.

Can you please tell me how you installed a custom recovery and flashed the ROM, please? I have the Redmi Note 9 and the MIUI 12.5.4. When it got bricked and I complained about it at my local "shop" (Something like a Microcenter), they reflashed it (thus losing all my photos from Summer 2021, around 80GBs of photos and videos with my family) I think they flashed a wrong MIUI ROM or an MTK firmware as the TWRP app reports the phone as "gauguin" (which is Redmi Note 9 Pro 5G) The ADB shell says merlinnfc which is correct. Also, I see some options such as Hotspot and multiple users as the first options on the Settings main page. I compared it with my classmate's phone as he got the same model as me. (But he was lucky enough not to brick it during an update )
Also, don't you have a sticker on the back of your phone with the IMEI numbers?
https://www.howtogsm.com/2021/07/repair-imei-xiaomi-redmi-note-9-merlin.html I only found this thing about the IMEI repair. I'm really sorry for the IMEI loss which is not common when flashing. ❤

I can't really have him install that because his phone won't go past the Galaxy Note 3 screen when he boots. This is what happened... he rooted successfully rooted with kingo and installed safestrap. He made a nandroid backup and installed a rom. The rom was force closing a lot of his apps so he decided to return to his nandroid backup. He first wiped everything and then he was going to restore but his backup wasn't there so he rebooted from there and that was his mistake. He can't enter safestrap anymore and won't get past the Galaxy Note 3 screen. This is all the information I have from his device.

Look in general section for restore to mj5. That will get him back to mj5.
I bricked mine with a botched 4.4 update file or something, I took it to the Samsung experience center at best buy, they flashed it back to 4.3 for me even with the boot screen saying CUSTOM

It is a different than official unlocking bootloader tool.
Sounds like the issue I have.

Even though I'm not even sure if mine is in EDL mode.
The one and only "life sign" I get is an unknown driver in Windows that pops up, when I USB connect it to my PC.
I tried at least 10 different drivers without success so far.
You won't be able to recover from this state. Your only hope is to disassemble the phone, unscrew the mainboard cover and do a testpoints method to open EDL port. Then flash china rom using MiFlash. Unfortunately that needs an authorized account.
thanks @Accidd
Does anyone know where the test points of the Mi 11 are?
This is how far I got right now

Mi8 original Qcn File

imei is broken. It doesn't see the sim. Even when I do *#06# I get the error "Cannot get imei". How do I fix this. I found some guides on the internet, but it wants the qcn file, but I can neither get the qcn file nor find the original qcn file on the internet. QPST Configuration application does not see the phone properly. When I say restore, qcn can't backup. SPC number appears as =000000.

Have you solved it, if you haven't, I suggest you to go to another xiaomi forum or android reddit sf, many active advanced user there..
here on xda not so many dipper user recently..
I haven't face this issues, so I can't give any idea. Best Regards.
@tsongming had them but idk if he still owns the phone since he's not been active recently, but there were some qcn files lurking around in this forum, I'm pretty sure you can find them if you search a little bit carefully.

I found the qcn file, there is no problem in that part. Now I am getting the below mentioned error so I can't load qcn file properly. Why can it be caused? It has original global miui rom in it.

If you linked your Mi account previously, then Mi Flash unlock tool has to work, if not, then, no way.
You can use SPFT at any time, no matter your device is locked or not, also you have this tool, be sure to properly install all the drivers needed, https://github.com/bkerler/mtkclient

Its doesn't matter for official tolls if its locked or not. Official tolls work with locked adn unlocked bootloaders.
You mentioned that you have "selenes" Redmi Note 11 4G which seems to be a china model. if its MTK device than SP flast tool is fine or else stuck to MI Flash only and check with the fastboot files.
Check the link as per the device mentioned -
Xiaomi Firmware Updater
The ultimate script that provides firmware packages for Xiaomi devices.
xiaomifirmwareupdater.com
You will need to extract the files using 7 ZIP till you get the image folders and try to flash it
If stuck share screen shots of the error message and make sure proper drivers are installed
If device won't enable change mode or ADB
Remove the back cover and disconnect the battery and reconnect it

Question Is it possible to install a Rom that has a different ProgID than the phone?

I have a Realme 8 Pro (RMX3081/GDPR/ProgID 20713).

The current ROM is giving me problems with the 4g network of my country Ecuador. I found a rom for Mexico and I think that could work better for me.
A few days ago I tried to flash it through msmdownloadtool, however, as it had a different ProgID, it could not be done.
For that reason I would like to know if there is any way to do this. I thank you in advance for your kind answers.
