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

Hello i have Global Device 6/128 GB unlocked.
i Successfull flashed xiaomi.eu_multi_MIMAX3_9.7.4_v10-9 Weekly and then i make full BACKUP with TWRP.
All just run fine.
Then i Updated via TWRP c...
Theni testet Ressurection Kernel 6.
After that i cannot use Fingerprint anymore.And cannot delet the Fingerprints that i learned with Phone.
Wiping Cache and Dalvik also didnt Help.
So i thoght its because the Kernel.
So i Dirty flashed again xiaomi.eu_multi_MIMAX3_9.8.1_v10-9 .
After tha the password of my phone didnt match.So i Make full WIPE of my Device "YES" in TWRP. FORMAT DATA.
Then i tryed to Restoere my Backup wich was make with TWRP.But it always Hangs on "SYSTEM Image" and FAILS.
So i tryed to make a new Install with xiaomi.eu_multi_MIMAX3_9.8.1_v10-9.
It boots and i can Use it but my IMEIs from SLOT1 and SLOT2 are "0" ...No imei.
Also it shows no Baseband and no Bluetooth Address.
MAc Adress is Present.
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 ?

I am in the same boat! exact same situation, did you manage to ever solve this?
hello everyone I have the xiaomi mi max of a friend following an update the IMEI and the baseband we disappeared when I insert any sim card it is not detect I tell myself that you have to manage the IMEI I try to reinstall different stock rom but not resolved I saw a tutorial to restore the IMEI with qpst but you have to unlock the bootloader but you need an active sim inside the phone to do it so i'm kinda blocking it i'll be delighted for some help thanks

Try fix QCN
any one has idea that how i got my phone the unknown baseband. " my phone was in 9008 mode due to rooting & using chinese app which moved my phone to 9008 mode automatically & no way to come back from that hell zone (9008) because it needed an mi auth to flash the whole firmware. really xiaomi ? it should be my phone & with my mi account i should be able to flash but these jerk company wanted to make bucks for their server too. anyway, i flashed with the auth account from some tool & after it my baseband was unknown. what was the reason ? i just upgraded my firmware & that's it. also, i haven't done any efs clear ? anyway to get that baseband back. i tried rooting & diag mode it doesn't work ? i tried the reverse eng firmware but for this model may be it was wrong because after flashing it with eng firmware phone keep rebooting.
