Mi8 Pro (China) Baseband Radio off error. Can anyone give qcn backup pls?

Hello everyone,
After I unlocked my device, I've tried most of the roms to find a daily driver. I installed and set them up then backed up all partitions with twrp for each rom so I won't have to reinstall apps, etc. Then I decided to go with xiaomi global rom, restored it using twrp.
But after that it couldn't connect to mobile network (No problem with wifi). I tried to fastboot flash stock China rom but it didn't fix that. A friend of mine suggested to restore qcn file using qpst but the problem is I didn't have any backup with that (I though twrp backup was for entire device, didn't know I needed that).
What do you guys think? Will restoring qcn with QPST will fix my device? If so can anyone share a backup for Mi 8 Pro China version. Or do you think is there another way to fix it?
Hoping you gurus will help me out, thanks in advance.

No SIM / No WIFI: qcn/xqcn files needed to restore IMEI/MAC

Hello All,
November update... It took a whole time to get my phone booting again but I don't have SIM or WIFI anymore.
I think my IMEI's are gone, even as MAC for WIFI.
I tried recovery image (that's what solved the boot problem).
I took backups but some parts seems to be corrupted so I can't recover from there.
Does someone have the (x)qcn available for flashing over QPST (or even over TWRP to change afterwards over QPST)?
I found different versions online but I think it's checked against model number; mine is: M1804D2SG (SI doesn't work)
Yes... I will change your IMEI!
Thanks!

Did you try to flash older build of stock rom?

Flash via MiFlash Tool, that worked for me

MiFlash tried,
I tried most recent version that was available, but yes that's an older version.
The corrupted data isn't even in the recovery rom.

Does not work unfortunately, just tried. In that topic it's more about sensors etc. not working.

Try flashing global firmware via twrp.

Also tried without errors but problem not solved.

Please someone upload.
My phone is still bricked :crying:

How may I help you? Give me instructions. Also specifically tell me how to remove my original Imei in that file. I'll then upload the files.

Missing WiFi MAC and IMEI - Mi 9

First off - Mods, I have the original box and sticker IMEIs if needed as proof.
I have been flashing between AOSP and Stock trying to fix a Microphone bug on my phone (see previous posts), when all of a sudden my phone will no longer connect to Network (IMEI unavailable error)
I went through every QCN backup + editing I could think of, even using my friends Mi 9 that we both bought from the same place in China as a QCN backup + my IMEI edits.
Everytime I edit the QCN and load it, the phone just boot loops immediately shutting down upon OS load. Using MiFlash back to stock didn't work, and I had to flash Evo X rom to get it to boot normally now, but I"m also missing WiFI MAC onto of my IMEIs.
I seriously have no idea what to do. I've tried every IMEI editing tool or Hex Editor in the book to put my original IMEIs back in to no avail. What am I doing wrong that cases it to restart loop when I push my updated QCN file?
Thanks in advance - Can provide whatever else you need.

As i understand you have China version of Mi 9, saying: "MiFlash back to stock didn't work" you meаn you have flashed official xiaomi china FASTBOOT ROM and it did't work?
Then i afraid the problem is deeper then in the ROM. Because by flashing stock fastboot ROM you flash everything that possible to flash, ROM and all images, with all setting like it was from the store.

Correct. Reflashing China ROM in Fastboot does not fix the problem. It fixes the bootlooping but not the IMEI issue.

Bad signal and wifi after imei restore

Hello. My redmi 9 was bricked so i used SP flash tool to repair IT. I used Download Only but my imei was gone. I used Eng rom and Modem META to restore IT. But when i restored two imeis phone was restarting on miui logo and miui recovery was showing
NV DATA is corrupted. So i reflashed Eng rom and using modem META i only wrote imei 2. Phone was working normally but my Wifi signal was very bad and my phone waz barely connecting to LTE/3G. I can make calls and send sms. Someone know what happened? I had nvram nvdata and imei backup on my sd card but IT got broken and i had to format IT. Please help this is very annoying and sorry for bad english.
I can't find any solution on internet.

Question Can someone give new NVRAM and NVDATA image to me for fixing IMEI problem

I lost my baseband and IMEI after flashing Redmi Note 11R from China Stable to EEA Stable, so I follow guides on Internet and tried to reflash it with SP Flash Tool. I use "Format All+Download" but after that, I can't boot into system but always fall into MIUI recovery 5.0 with "NV data is corrupted" message.
Then I tried to use ModemMETA, but when I press write button, I always got operation timeout error, so I think maybe those partition were damaged.
Will flashing a new image fix issues?

I can give you that files, but it won't help. If you delete nvram - than your phone will not call any more, how to fix that - only on service firmware, but when you upgrade it to miui, no phone calls. I have the same phone, same problem, and no solution. Maybe in some month

Thanks for your helping, now it can at least boot into MIUI, not recovery. But the problem is ModemMETA tool now stuck at "Connect to MD" with good nvram files. Does that means I can only use the tool with corrupted nv data? That's weird. Also, I still getting unknown baseband and IMEI with China ROM, what version and region was your MIUI when you backup those files?

I have India, but it won't help you. If you want to recover your phone, you need to flash ENG rom(Format + Download) to use Meta Modem, then write only second IMEI. I have ENG rom if you want https://disk.yandex.ru/d/HFA-nWmHW8x1Kw
But then when I come from ENG to Stock - my baseband lock, phone no detect simcard. If I flash another modem, phone see simcard on stock, but no calls. I think it's becouse of baseband from nvram, nvdata + md1img that can't be applied on new phone with out change of Imei in that files, Meta Modet can't change IMEI in that files, it can only work on empy nvram, nvdata but with that files my phone don't calls.
So you need to flash stock and use special soft life Unlocktool to repair IMEI, I will pay some guy to fix my problem becouse I don't have solution for that. I spen about week on that problem in Internet - there is no solutions yet for that mode, Redmi Note 11E, 11R, 10 5G (light).
