So for now it will be 2 weeks of this anoying issue that phone radio just disapers, in setting section it just say "radio off", first I thought I am lucky and factory reset helped but as time passed it hapened again againa again..... For now it seems completely shutt off, because nothing bring it up online. I had made diferrent tehnices like bringing phone in diag mode that for some time helped and setting some of nv items to defaults(found default walues in internet), changing radio mode in DFS but as I sad now nothing helps. So I ask someone of you guys for helping hand to share efs partitions efs1 and efs2, to modify them whit mine setting(esn, imei......) to try this last chance. Or I will need to buy other phone as mine dosn't had warranty. And if I succeed I will make universall efs dump without esn, imei, meid... so they can be filled with your stuff.
So I am asking for someone who had twrp backup of efs or can dump booth partitions of unmodifed band N5 D821 international variant. And I can promise I will not use your imei esn and other settings as I can read mine so they aren't damaged. And please if you share it do it with pm as thoose partitions contain your phone radio info and provide radio version who you are using.
P.S if someone had simallar isues and had repaired it please share it
[EDIT]
Please share efs partition I will pay you if it help me because new mb is 190USD and I realy like my phone.

Hi guys!
Yesterday my firmware update went terribly wrong and now I have a device that states that imei and baseband are unknown, so I my both sim-cards don't work.
I've tried several types of IMEI restoration, but none of them worked.
Unfortunately I don't have any backup for nvram. So, my guess is that there is a problem with EFS partition on the phone.
In QPST NV RF Manager I see my real IMEI from the box, so I guess it is still present, but my baseband doesn't work. Can you please suggest any help on recovering the baseband? Or if it is possible share with me modem backup or nvram backup without IMEI (I've seen on this forum that one guy with Samsung S3 had a kind of the same problem and he was given a working nvram backup without IMEI (IMEI was 0/00)) I can write my IMEI then, if baseband works again. Will appreciate any help.
Send it back. Only the oem is legally able to mess with the IMEI.

Well... I have managed to make it work again and my original IMEI is back. The only thing I had to do is to restore a working NVRAM backup (from another device) via QPST. So, it wasn't that hard. Much simpler than sending it back to China.

If you restored the file from another device then it won't have the right IMEI.

It HAS right IMEI, I checked it with the original box. No need to put up an argument about it. Both devices (mine and the one which was backupped and restored from) are working fine, bot have ORIGINAL IMEI numbers and no errors considering networks or MI accounts. So, actually I have no idea what you are trying to tell me.

I'm not making an argument. I'm trying to figure out how a number which is supposed to be hard coded into the file is then restored by restoring the files from a different device.
As these devices are not sold in the states learning as much as possible is a good thing.
Glad you got it working.

Okay, sorry. I will try to make it a bit clearer=) This device is not sold in Russia either (officially at least), so the only way to get it is to buy from aliexpress or ebay or anything else. In that case the buyer doesn't get any guarantee or official support. So if the device is broken and can't be restored it turns into a garbage. I believe that in the US the situation with that kind of devices is almost the same.
Now, if You are not familiar with QPST it is a software package for qualcomm based devices which can make backup/restore of some non-firmware software from the device (like IMEI, ESN, Baseband, LTE Channels etc). As for IMEI number, basically, as You've said it is hard coded into device so it is pretty hard to get it changed or fully deleted. Here we come to my case of unknown Baseband and IMEI. Though via phone settings I could see: "Unknown", my IMEI didn't change and was stored in the device. The "error" or smth like that happened after the factory reset and my guess is that the file structure of NVRAM was changed. So, backup of NVRAM taken from the working device didn't actually have IMEI or ESN in it, but it has the right file structure without any errors. That is what happened, the file structure was restored without changing any factory numbers.
If you have any questions, feel free to ask

It is almost the same with a few exceptions. One being that their devices are banned from all people that work for the government, sometimes they get stopped at customs due to copyright issues and with the latest news about them coming loaded with malware, most won't buy them.
That makes sense in a way. Not sure why a factory reset would mess up that part of the device as it shouldn't touch it.
Thanks for the info.

Hi! Have you tried flashing China developer rom with Miflash?
Second option: Connect to your PC and run QPST according to one of the manuals (in order for your phone to show up as a COM), run RF NV Manager and look up your line 550 NV_IMEI if it is filled with numbers that are the same as on your box (check HEX above them and numbers should resemble yours from box but written in opposite direction, eg: on the box it is XXXX69XXXXX in the QPST it will be 96). So, if your IMEI is at its place than all you need is a working device from someone to make a backup. Backup must be made in newer versions of QPST in *.xqcn format and than restored to your phone with checked box "allow ESN mismatch"

The easiest way is Xiaomi customer service.
First check if your Xiaomi customer service has warrant coverage after bootloader unlock. (Some country does, some does not.) [ie. warrant the physical device; rom state or bootloader doesn't matter]

you wont be able to restore qcn even if you have unmodified qcn. newest 2021 xiaomi devices got RSA on both sim1 and sim2 modems. qfil will write it but after reboot it will be back to stock so you need your EFS.

Yeah did told them to check, but didn't say it will be free of charge. But Xiaomi definitely will repair it or change one for you.
Even if you find someone on the net, many will charge you some dollars. And you don't even know if they actually can fix it or just a scam.
Unless there's some way to bypass, or an exploit to make EDL work, for general user, Xiaomi customer service is better and safer.

Hello!
I wanted to change my MIUI version from global to eu, so I installed TWRP and flashed the rom. The problem is that somehow while doing this it wiped the IMEI, and wifi/bluetooth mac address. (so it doesn't see sim cards, and wifi networks)
Is there any way to restore the factory IMEI + the mac addresses? (I have them written down, and on the box)
And how to make sure that I don't wipe these things again?

You need to hex edit your IMEI into your QCN file and flash it back to the device. Also from QFIL.

There are a lot of guides on XDA and elsewhere for the steps. However you need to first secure a working QCN file if you don't have a backup of your own and know the IMEIs in that file, so you can locate and overwrite with your own IMEI. Without that, you won't get far... I don't have a QCN file for this device on hand, maybe someone else here does and an share with you...

Is there a solution to unlock bootloader always Error11003
@Andrologic
Hey! I have been long trying to recover my nulled IMEI on ROG5. Every single tutorial I can find asks for a qcn file along with hex editor to input your box IMEIs. All follows up on my end until I use Qfil to restore a changed qcn file. It only writes till 2% and then phone goes into ramdump screen which means there's some kind of IMEI write protection on device or something like that. Because all other IMEI writing methods fail the phone to same RAM Dump screen. Desperate for some help.
Also there seems to be a problem getting diag mode to work on all stock ROMS. The only way diag mode works is by using ENG factory firmware on my ROG 5 which enables diag mode by default. The Asus_volte_su_fixed apk provided by @twistedumbrella Also doesn't enable diag mode on ROG5.

This is not based on my own experience - but it looks like you may have access to write the IMEIs to this device via one of the ASUS Key partitions - in which case you may (or may not) be able to bypass writing QCN altogether.
I forgot the name of the guy who posted it, I believe it was under a CN>WW conversion guide - try to look it up and give it a try...

The Imei part was mentioned in the very last part of thhis guide:

Someone tried that for a seperate reason and apparently it changed their IMEI:

Now, When I change the asuskey4 file, My IMEI do appear in the bootloader screen but when phone starts, it goes into a boot loop which stays even if I reflash the ENG firmware or stock firmware and ending in RAM dump screen.
Erasing the modemst1,modemst2 and fsg partitions from the phone does allow to get out of the bootloop. But shows Null Imei in the phone, while showing the IMEI in the bootloader screen.
So, apparently if I cannot restore the qcn file, There's no other way.
But Restoring QCN in ENG factoey firmware using QFIL or QPST only goes till 2% and then fails and phone goes to RAM Dump screen. Which apparently means that the phone has somekind of NV data write or IMEI write protection.
Writing QCN via Qfil goes till 2% then phone turns off and then status goes this 164% after which it shows that:
2022-05-05 08:53:19.685 Subscription ID:1 EFS File:/sd/mru001_ext_Subscription01, Function:NV_Tool_WriteNVsToMobile, Event:3 164%

Attached is the log file from Qfil.
After this, phones goes into RamDump screen and when I hard reboot the phone, I can see IMEI changed from Null to 0 but still not my original IMEI :/
using qpst to restore only goes till 4% after which phone gets stuck in Ramdump screen.

Hi, Guys. I have the same problem since few days... Hope we will find a solution soon.
You cannot use others's qcn file to restore your imei. The imei store in fsg, modemst1, modemst2 also in your qcn file. If you use others qcn then they don't match each other, you'll failed to restore. The key: you need to empty the partition of fsg, modemst1, modemst2 in oder to restore other qcn file, but the system is read only so you cant do anything.
