Hi everyone, I've purchased a Redmi 7 outside my country (Argentina), and everything worked as expected. Then after some hours using it, the phone started updating. After the update completed my SIM card was not detected anymore and both IMEI numbers show up as UNKNOWN.
I've downloaded some tools to restore the IMEI but in order to do that I need to open Diag mode. The codes (*#*#717717#*#* and such) won't work, showing the message "Open diag failed". I've read that to enable Diag mode, the phone needs to be rooted.
To be rooted, the bootloader needs to be unlocked and to unlock the bootloader, I've to log in MI Account in the phone but is impossible without a valid IMEI.
I don't think I did something wrong since I just bought it and used it normally for a few hours with the SIM card working correctly.
I've already written an e-mail to the Xiaomi support contact but got no response yet.
What can I do? Is there a way to get into Diag mode without root?
Thanks in advance
You can try flashing a fastboot rom of your region through fastboot mode
Is there any possibility to change imei on Redmi Note 8 Pro. I already've rooted and twrp'd it.
Surely there's a way, but should you actually do it? Of course not.
Why not? There are good reasons to do it!

Yes, you can and it's very easy.
This tutorial shows how to change the IMEI with and without root: naijaknowhow.net/how-to-change-imei-of-all-mtk-android-devices/
Since it's MTK sure there is a lot of ways to do it but are you sure?
Changing IMEI is illegal in most countries / will break your ability to call, sending / receiving SMSs.
Except if yours was null/invalid (multiple zeros) and you want to change it back.

Doesn't work, very old tools, not that easy like you guys write.

Have you tried maui meta?
Version 10.1816.0.1 just says boot, phone turned off, nothing happens anymore. I boot manually nothing happens in the tool
1920 the same and I got connection with the Redmi via W10, I can for example upload files onto Redmi
This is the right tool. I just rewrote my IMEIs with it. Make sure you have device drivers installed or it will fail to connect.

Did it boot to meta mode?
Have you followed instructions? It is nearly the same in every video for IMEI changing.
On the Redmi Note 8 Pro, If you ever lose your IMEI and have a full TWRP backup, restore the following partitions:
- nvcfg
- nvdata
- nvram
- persist
- protect_f
- protect_s
Most notable protect_f and protect_s. This apparently contains modem files. Restoring the others fixed an issue where it didn't ask for MIUI account login after factory reset.
m1906g7g this is my device, maybe I need other drivers? I tried so many. For example "mt67xx USB Vcom" and others.
Doesnt work, of course with Win10 I had to disable "check driver signature". I disabled, that is ok now, but still, which drivers do I need? I use Modem Meta 1920 and it always stands on "Boot..."
CANNOT FIND THE PRELOADER/BROM COM PORT to boot ...pls check USB Driver Version...
When I put preloader USB Driver in Device-Manager, then it says error 10

VCOM MTK drivers i believe
Edit: this one https://androidmtk.com/download-mtk-usb-all-drivers
DUT IN META MODE! it goes to 19% at least....
XTM_Miracle Thunder 2.82, did something "done" but nothing happened, same IMEI
Just curious? What would be the benefit if any to changing your IMEI?
Not seeing a point to it. I had an old Lenovo K3 note an from time to time my IMEI would dissapear an I had a devil of a time getting SMS or calling to work when it did.
Luckily some kid on YouTube invented a software that replaced the default IMEI. An only then the cell worked.
So if removing it causes that many issues then why change it?
hello
yes there is a way.
first of all you have box like UMT Pro.
then you can. its complicated but you can
and you have to flash ENG firameware.

Did you mess up the imei files or is it a blocked (reported stolen) phone? Discussing imei changing is not appreciated and most times even not allowed to discuss on XDA.

in Türkiye goverment doesn't allow phones that brought from abroad. you have to pay lots of taxes. almost as much as phone price. thats why people trying to change imei.

But when I have changed data serial and imei and write to phone back Modem META indicate upload compleate OK. But after reboot in phone when I turn it ON stay the original parameter phone not changed parameter.
what do you thinking about whay to change IMEI and Serial
I have a redmi note 8 pro, hacking * # * # 4636 # * # * for reasons it does not support the vodafone italia "volte". i disabled dsds now i no longer have access to sim 2 or imei of sim 2 has also disappeared and there is no way to restore it in the menu. can you help me? i have imei 2 written in the package. Thank you PS miui 12.04.0 eeu no root!
I am losing my mind already. I have acquired the bootloader unlock authority permissions or whatever, but the Miunlock tool does not work, keeps giving me the error "Couldn't verify device, can't get info, connect again"
I recovery'd to a lower MIUI version global rom and tried again, it didn't work. I have done mi support many times, and they told me to contact my seller for repair as it's not letting me unlock bootloader. I have also tried using "XiaoMiTool v2", but the error I get is this:
"Xiaomi procedure failed: Invalid input argument: null product"
"Error family code: xiaomi_exception"
"Error origin:xiaomitool.v2.procedure.install.FastbootInstall$4.run(Unknown Source)"
Unable to contact seller as they are gone from Amazon and apparently Xiaomi devices aren't released in the US which does not help my case. I'm wondering if anyone knows how to fix this?
Try with another data cable. It could be that device is not recognized. After conne2the cable, first go in Device Manager in Windows to see if device shows up correctly or shows as unknown device with exclamation mark.
Happened with me when I was using Sony Xperia few years ago. Removed extention cable and used Sony's own cable, it worked.

After accidentaly use wrong qcn file on my realmi 6 pro, i lost my imei and phone not showing on QFIL port. Its sho like this (?(0), or No phone, or sometime show bord number like MSM899..), Not all permanent,
Thatsway Not posible to flash back orginal QCN file how to fix this.
#Diag mode working (Device manager and Qfil port showing COM PORT.
*ONLY PROBLUM IS PHONE NOT SHOWING.
#i have unlocked bootloader.
While trying to install a Custom ROM, all went wrong with a hard bricked Redmi Note 8T as result.
Have been able to revive the phone in EDL mode (Test Points method). Now running again on MIUI Global 12.5.5 (RCXEUXM).
However, the IMEI's are nulled, can't activate a SIM card. Only WiFi works.
A first, essential step in the process to repair the IMEI's, is to open the diag mode. Found a few methods, but none of these methods work.
Not via *#*#717717#*#* (Open diag failed), not via adb devices // adb shell // su // setprop sys.usb.config diag,adb (Permission denied).
The phone is rooted with Magisk; recovery OrangeFox.
Does anyone have a helpful suggestion how to proceed?
Follow-on: Meanwhile, I've been able to open the Diag-mode. Apparently, one or two switches in Magisk had masked the rooting of the phone.
Now on to editing the qcn-file with the correct IMEI's. First,I have to figure out the location of the two IMEI's, and then to correct these into the correct values.
To be continued...

I have had the same problem with my previous Redmi Note 3. And I tried so may ways to re-write the IMEI number. Finally I found a little software on the net and using my computer I was able to re-write the IMEI number to the phone. I was a long time back, so I dont remember the exact name of the software. It was something like IMEI writer (root). Connected the phone which was also rooted. Then opened the software on my PC and the software asked for superuser access, which I granted on the phone. Then there from the pc using the software I entered the IMEI numbers for both sim1 & 2, and applied then reboot phone. After reboot, the phone then detected the simcards and the imei were back.

My current problem: I can find a .qcn file and have to edit it with the proper IMEI's. Found a Qualcomm IMEI Rebuilder tool, but that tool doesn't work. With a Hex-editor it is difficult to find the proper location. Found the location of one IMEI and then saved the file with a different name. Loading that file into the Rebuilder tool indeed shows (one) correct IMEI. Have installed that file with QFIL, but when I check with *#06#, it shows a completely different IMEI...
Meanwhile, I've searched for IMEI write (root). Found IMEI Tools (ROOT)_1.4_apkcombo.com.apk.
Prooved incompatible for my phone.
Then found qualcomm-smartphone-write-imei-tool-v1.01.apk
Tried that out, but couldn't establish communication with the diag-COMport.
In fact, I can't activate the diag mode any longer... Tried and re-tried, but all in vain.
When I enter the last command ('setprop .... etc.), communication via the USB port is also stopped. Re-establishing that doesn't make a difference. No COMport appearing in device manager or in QFIL...
You need special tools like UMT or Hydra to write Note 8 imei

UMT works with dongle? Price?
I tried Hydra, but got a Trojan Horse warning, and therefore broke off installation.
Umt needs dongle.
First restore original qcn(unedited) then try flashing ENG firmware.
