Redmi Note 5 AI baseband /imei problem - Need help

Hi,
I have a redmi note 5 AI/Global which I've had problems with - it's unable to get a signal with the sim card. It lost the imei numbers (and I'm assuming Baseband) with a TWRP restore where the user tried restoring the efs/modem partitions. The phone does pick up the network, but it doesn't show any reception. The sim card works fine in another phone.
I have:
1. flashed the baseband using the model's qcn using QPST
2. Changed the imei back to default using the imei change tool
It's currently on the latest dev rom. I'd really appreciate some help with it

try to search for qcn for the same model and restore it on your phone, it will work for sure

I've been looking for it, unfortunately I haven't been able to find it - it's M1803E7SG

Locked bootloader, no baseband, greyed out OEM unlocking after flashing OCX27.109-36

Hello,
I have a problem with my Z2 Force TMO US version. I live in Poland. I bought the phone on the internet and it was TMO simlocked. I did the temporary unlock to check if it is working. Then I wanted to flash custom rom (DU in this case) and my problems has begun.
1. After first attempt of unlocking boot I got it unlocked but couldn't flash any custom rom. I figured out it is TWRP problem (flashed 3.2.2-2 not 3.2.1.1).
2. Flashed TWRP 3.2.1-1 and I was able to flash custom rom.
3. After flashing custom rom I lost phone signal: I'm getting no service and zero signal bar. I checked *#*#4636#*#* and noticed that I have radio off. I had IMEI and BASEBAND then.
4. I tried many other roms to get my signal back but no success.
5. I flashed stock TMO and was able to unlock simlock temporary again but it has no service and signal again. Radio is off.
6. Today I tried flashing stock OREO OCX27.109-36 with locking bootloader now I'm stuck.
I have locked bootloader and no baseband which means I don't have any signal or WIFI (mac is 0). I can't connect to google account so I can't get oem unlocking option - it's greyed out.
Can somebody help me with enabling OEM unlock? Or even better can somebody help me with getting signal back?
Thanks in advance for reply.

Try flashing the newest TMO firmware, which is the only thing you can flash with a locked bootloader. Check post #2 of the return to stock thread for the flashall utilities and the TMO flashall. The latest firmware provided for TMO is ocx27.109-51-7

You can do it
, I already had this issue with my moto z2 force in Morocco , so what I did is I connected the phone to internet via bluetooth and when I added my google accounte the unlocking oem in dev option was normal , so I was able to flash roms again . Hope this will help you.

Use pdanet app, you need two Android devices. Connect using Bluetooth...

Thank you guys. BT tethering helped. Thread can be closed.

How did you connect to Bluetooth to get through first start up? I can't get to Bluetooth settings to pair. I have this issue currently...

Have you tryed this: https://android.gadgethacks.com/how-to/downgrade-from-android-9-0-pie-back-oreo-your-pixel-0183424/ ?
I guess it will be the same for our selfphone with different fastboot files.
A lot of people are having this problem after upgrading to android 9.
Good luck

Having same issue after downgrade. SIM slots are swapped. If I replace SIM in slot then now need to reboot phone in order that phone recognizes SIM is inside and connects cellular. Any guide how to get this sorted for Oreo?

same here. If my sim card could get signal, it will lose it again. Disabling sim 2 is could get this fix, but I need 2 sim card active. Still no one know how to fix this?

Same problem here!

Same problem here!
Any Solution?

For solve SIM issue:
1. Install Oreo via fastboot normally.
2. Flash modem.img from Android Pie via fastboot ("fastboot flash modem modem.img").

Where can i find that modem file and can someone please tell me procedure step by step?
Thanks

Modem.img is in OTA folder of the tool.
Put phone on fastboot mode - turn off then turn on with vol down + power
In tool folder click on open CMD here
Enter CD OTA
Enter command "fastboot devices", there should be some id (your phone)
Enter "fastboot flash modem modem.img"
There will be Success result
Enter "fastboot reboot"

Unzip and replace modem.img with that of Ota on android 9.
Then flash from Xiaomimiflash.
select Clean and lock

So i searched Internet that i have to restore the EFS Partition.
I done zthis but Imei is again not showing.
Is my Phone now bricked or is there a chance to get my imei back ?

Try flashing stock fastboot rom with MiFlash.
And if you have a 6/128 model it is a China version, Global version of that model doesn't exist. So if you flash Global fastboot rom keep in mind to choose 'Clean all' instead of 'Clean all and lock' in MiFlash. This is very important because it will brick your phone when done wrong.

Mismo problema
Hello, I am in the same situation although worse ... I have a bootloader locked and since I do not have imei I cannot activate my xiaomi account.
In the manual I have read that you are backing up the .qcn file from the phone. I'm wrong? My problem is that I cannot activate the USB diagnostic mode.

Do you have also a China Version of that Phone and a Global Image was flashed ? 6/128 GB is sure China Version.
Yes i need a .qcn Backup from another Phone with an "imei" Present.then i can add my imei and flash back the qcn file.
I tryed everything.Only thing i didnt is flashing a China Fastboot Rom. Its because i flashed 10.3.3.0 Global ....but at the moment only china 10.3.2.0 is present....
And it will Hardbrick the Device if i try to flash China.I must wait that Version 10.3.3.0 is out.
The thing to enable diag mode is..... i did it with ADB.But i think phone must be rooted.
# adb shell
# su
# setprop sys.usb.config diag,adb
have you tryed to make a clean flash via Miflash with fastboot rom ?
