Have you simply formatted ( Note that I said format and not wipe) the phone and reinstalled stock?
If yes, then QPST is the only option, and if you used it correctly it will usually work, unless you have a hardware issue. Do you have any recovery backups that you can restore?
These QPST instructions are all over the web, but the steps are always the same. I have repaired IMEI twice but on a different device.
If not you will need to find a donor QCN and retry QPST. ( QCN's can be found here on XDA and on Xiaomi forums) Make sure that you get all of the correct files for your Mi8 ( Your version of the Mi8)
and you can follow the instructions here: https://medium.com/@shekhawatkoki/f...-snapdragon-devices-xiaomi-mi-a1-2ed533548d32
Although these steps are for a A1 the steps are standard across Qualcomm devices. Just be sure to use the correct files.
I included the IMEI rebuilder tool and a QCN attached below. I keep these in case I ever needed it for myself and I have no idea where I got them. Use Google and research the issue heavily before starting. Be sure to try formatting and restoring the full stock Rom via ADB first before doing anything else.
Good Luck.

Sorry for the delay, I have downloaded and used files from this site a few times the past and had no issues whatsoever. However, that was a long time ago and it now looks like a completely different site. But they have an up to date security certificate. However, I would suggest that if you decide that you must use QPST, that you create a developer account with qualcomm and download the qpst tool from them directly. This way you are getting the most up to date tools, and you can get support from their forums.
FYI: you need to enter Diag mode before you can use the QPST tool for IMEI manipulation. Also, the tool will only affect Sim card 1... well that is what I have heard in regard to Xiaomi phones. Beyond those suggestions, as I have mentioned numerous times, on various threads, I do not support QPST with the Mi8. Because I have no experience using it with this device so I can not provide help based on experience.
The last time I used it years ago, and it was for the sake of experimentation. and once you change the IMEI it is difficult if not nearly impossible to restore the phone back to it's originally IMEI unless you have your original QCN backed up.
To go on, I made the post above almost a year ago, and frankly forgot about it. My perspective has changed, I would strongly suggest not using QPST or the QCN file to fix your phone. and to instead attempt to manually repair your phone using the steps suggested on my persist thread. if you have already tried everything on that that thread there is not much more I can offer, it's too risky and I don't want to be involved with permanently damaging your device. Online IMEI Repair services exist, and that may be your best option if the phone restoration route doesn't work.
Another option is using a UMT Box, and following an online tutorial. They cost about $50.

Mi9T Pro no IMEI, no sim card signal.

Heyo!
My Mi9T after updating to miui 12 stopped getting sim card signal and a local repair shop said it's because the phone has no IMEI number!????
What should i do now? How to resolve this issue?

Flash persist.img in recovery if you have a backup....

3 STEPS for you :
1. well , if you don't have efs/modemst's backups to restore, ITS NOT LOOKING GOOD.
2. next logical step try a fastboot rom flash , if IMEI is not restored , ITS BAD.
3. your device needs an IMEI repair , better done by a proffessional (he uses some hardware to repair the imei).
Best of luck to you

You cannot find them, they are specific to your phone , they have info on your IMEI numbers and device specific IDs ,so flashing other people's files would mess up your phone even more.
DO not flash FASTBOOT Image unless you backup your "persist" partition as you would lose other important stuff that cannot be recovered.
You have to root your phone , backup your persist partition , then flash Fastboot ROM to see if your IMEIs are restored.
If not , then IMEI repair is the way to go , just find a good repair shop and they will do it for you.

Trying to FIX IMEI (null)

Hi friends.
I'm trying to fix both my IMEI, they currently show as empty/null. (I did a full format using SP Flash Tool. Now i know, never do that...)
I'm with TWRP and root installed. I followed every single guide I found reagarding "imei fix", none of them worked.
Most of them rely on a "meta mode", and I'm suspecting my Redmi doesn't have it, only EDL.
ps: if someone got a nvram.bin and nvdata.img I think I can do it myself, with SP Flash Tool.
Any help is highly appreciated

you can't recover both imei. only imei 2 (with Enginner Rom and Modem Meta)
nobody should give you any nvram , nvdata or any partition because that is private and unique info of each phone.
The only thing you can do is going to Xiaomi Service Center ... and don't try to modify a MTK phone again... Cheers !

Question Help with an unbricked Poco M3 Pro

Hello guys, after some struggle trying to unbrick my poco m3 pro, i faced a new probem, my IMEI has gone, as a noob that i am, i didn't made any kind of backup, i'm trying alot of ways, and still i didn't had any luck to re-write my IMEI (i still jave the numbem on the box of the phone) to the device, i'm using linux, almost everything that i found is to windows, does jave any kind of tool for linux, or i'll have to put windows on my laptop just for this porpouse?
there is anychance to use mtkdrive tool, the same used to bypass security for sp tools to do this ?
thanks for now

if your mobile services works, write imei is not necessary. and it's a dangerous operation. so if your devices now works fine, my suggestion is DON'T TOUCH ANYTHING
all my old phones that after modding lost originals imei worked without problems
a mobile sim could work also with all imei numbers=0

sadly my mobile service don't work, i keep zero signal, and when i try to get IMEI numbers on Settings > About device, it says unknown on both IMEis

ok
first try your sim into another device to be sure is not damaged
second search xiaomi redmi note 10 5g fastboot engineering rom and flash. this rom should repair some high problems like your.
if boot and all work fine, update to miui13. good luck

its only information and you can use Maui Meta in Meta mode if you enter edl/testpoint, for me the first time lost two imei only return The Second imei, but send to waranty and change the Phone.
of coursed use a Semi Profesional Tools.

Did you find a fix? And where did you go wrong? Please let us know the mistakes you made so that we don't.

Redmi Note 9 - How do I restore my IMEI? I don't have a backup of my nvram/nvdata but I have the numbers.

How do I write IMEI along with baseband version back to my phone? I really don't want to risk bricking it again, that's enough stress for me in the past two days
I heard that I can only flash IMEI 2 back to it, and if I want flashing IMEI 1 as well I'd need to install a custom rom on the phone. So if that's a solution I'd love if someone could help me with it. MIUI 13 is slow and laggy af (which is the reason I bricked the phone in the first place, to install a better ROM).
But here's something, when I flash the phone's firmware through fastboot, issues start to rise (as per my experience with it so far), but through SP Flash Tool, it's alright. So I'd love to know if installing custom ROMs using the tool would be alright, if not then if recovery is required or if fastboot is fit for the job. If that's an issue I'd love if someone could give me advice when it comes to it.
Old post 1: (not my current situation)
"Long story short, I bricked the phone and after months, I've finally been able to repair it (downgraded from MIUI 13 to MIUI 11), but I lost my IMEI. I have the phone's two IMEI numbers, but I could not find any tool to help me write it to the phone. Either that, or I don't know whether the phone should be turned on or off, or if there's any special mode that's required for that matter.
Help would really be appreciated."
Old post 2:
"It happened after manually installing engineering ROM on it, now I can only doubt it's BROM mode that's working and nothing else, but I'm not sure. SP Flash Tool doesn't want to work with the phone since I want to flash the stock rom back. I really need help please."

The reason why my phone broke in the first place was due to flashing a misc.bin file after following a YouTube tutorial. It was part of a process to download twrp on the phone unofficially. Since then I started looking for ways to fix it until I finally found a post that had to do with fixing nvdata corruption (which was the error I had prior to fixing the phone) which helped.
So yeah, I don't think I can trust flashing ROMs on my phone as much as before, but I'll still try the engineering ROM thing.

So um...it bricked. This time worse than before. It doesn't turn on at all no matter how long I press the power button. It was after I manually flashed eng rom.

Yep, it doesn't show up as it's name or "Android", it shows up as MediaTek USB Port (COM3), that's why I doubted it to be in BROM mode.

I always recommend a NV Backup before messing up with your own device, that's all I know.
Download the file attached here but remember you can fix only second IMEI using this method. Please don't try to fix both IMEI or NV Data will be corrupted again.

The guy in the video is using MIUI 12, I have MIUI 13. I don't know if that's an issue but someone in the comments said something about MIUI or so. I'm not a professional but many times when I see tutorials they're very specific with the MIUI version.
Also, I'm not sure how to back up nv data, do I use mtkclient or is it somewhere in the attachment you sent me?
And one more thing, my phone's baseband version is unknown, could that affect the process?

The phone keeps rebooting when connecting it to Maui META. Like it shows META MODE at the bottom of the screen but then it turns off. Now it's bootlooping. I guess I'll have to flash MIUI on it again. At least I still have access to fastboot and recovery.
Update: NV Data corrupted after flashing MIUI, but I got a solution that hopefully works.
Update 2: After flashing MIUI 11 (along with some other nvdata and nvram files, i think they're just empty), it works now and the error is gone. But as I said IMEI issue's still there. Maybe I would need engineering ROM for this one? Although it bricked my phone before.
Also, the phone started bootlooping before attempting the Maui META thing, so maybe it's either the manual formatting of partitions or the files I flashed on it.
