You need to use the correct firmware for your device.
Here is a website that has firmware for the Global and the Chinese version of the Mi8
Here is the chinese Firmware link
https://xiaomifirmwareupdater.com/#stable#dipper
If you continue having an issue after upgrading the firmware, you will need to use QPST to repair your IMEI

Yes I misread and was thought that you were also having cellular connection issue, in addition to WIFI, BT etc. You did not provide very much information
Did you try the most basic steps with resolving your issue.
Such as, fully resetting/or forgetting your Network and then resigning back into your WIFI?
Did you rule out the issue being with your router, or duplicate IP address, did you power cycle the router?
Did you fully wipe your device before switching to a completely different rom?
Your issue is probably an encryption issue, did you first fully wipe your device, including formatting user data? If not that very likely the issue and formatting resolves will absolutely resolve encryption based issues.
In fact, the more that I think about this issue and how the issue improves when able to sign into Mi-Cloud, I am certain that encryption is the problem. So back up your memes, and fully wipe and FORMAT ( not wipe) user storage ( type yes) reboot to recovery, then reinstall your rom and you should be back to using the phone without issues.

I am not sure if possibly English is your second language so I will give you the benefit of the doubt, a friendly tip, and another thing to try.
If a stranger on XDA is spending their personal time attempting to HELP YOU, with YOUR issue and providing you with a plethora of things to try, you may want to use your good manners and thank them for spending their time trying to help you, instead of briefly stating, I tried everything and it did not work. You would be amazed with how many doors simple appreciation can open for you. Next, It's called troubleshooting, If I had a definitive answer, with a definite solution I would have told you.
With that in mind here is another idea of something you can try,
It's pretty much all that is left to resolve, at least AFAIK.. So either this works or it's probably a hardware issue. Or an issue that requires using QPST as I stated originally, regardless of your IMEI. There are a million sites that describe step by step QPST steps if needed, I recommended.
Any of the steps below, you do at your own risk.
My last guess is that you probably wiped your persist partition by accident
You will need to restore your persist image and then you should be back in working order.
Important: you need to locate the correct persist image from the correct fastboot rom for your device. You can manually extract the file from the stock fastboot rom for your specific model and then push it to your device via ADB
As mentioned, you can find the rest of the additional steps with Google
@sear01
If you tried everything else, this post is probably the solution that will work for you as well.
Again at your own risk
thanks, I speak spanish and try to install the persist for a while the detail is that in a week I turned the wifi out of nowhere and now that the rom Pixel Experience was updated, the wifi again failed. Excuse me you could detail the steps I already made the flash of several rom both of China and global by Miflash but until now I do not expect anything to understand my desperation.

Yes, I am getting ready to go to bed right now. Tomorrow, I will put together some instructions for extracting what you need from a fastboot rom.
I need to know if you have a Global of Chinese device.
If you have a global device, I can make a TWRP flashable file for you, which I will send to you via PM, I am happy to help people who appreciate my time.

Okay then, here's the cliff notes.
I have good and not so good news, Keep in mind that repairing Mac address issues, Imei, QCn issues is the same for all Qualcomm processors, it doesn't matter if a post said this is for the Redmi 10, in fact I can't find the link at the moment but Qualcomm themselves published a guide with similar steps across the spectrum of chips. ( Just make sure that you only flash driver ( firmware images ) for your Global Mi8 and not the proprietary files from the links. Otherwise the instructions are the same, various versions of QPST will work, PC drivers, android drivers will also work. If will only benefit you to use the latest version of any of those files. If language is a issue, use chrome with the translator plugin .
I made copies of my personal persist files and spent the time to create the main files that you need and posted them Get the files here : https://mega.nz/#F!0NAXEK7S!Bj_hTKSz2_hMKDjOEocNrg
Install the version of TWRP that is on the link above, Create a folder called restore or whatever you want and place the downloaded files from my Megalink inside of that folder, make sure that they are not compressed. Next, place the folder inside the Twrp/Backup/ <<<< Place your folder there.
Boot to Twrp, click restore, and you should be able to restore the persist image.
If it doesn't work then use ADb to push to your phone. Google it, the steps are listed a billion times on countless sites, and I do not have enough server space to upload a complete recoveries, and plus I will not share my EFS or QCN
If that doesn't work read this post : https://forum.xda-developers.com/mi-8/how-to/how-to-fix-mi8-sensors-t3844551 ( Note the persist image, present. But also much older. However, it's still worth trying.
Worst case QPST, should absolutely resolve the issue
If what I listed above fails go here: https://forum.xda-developers.com/redmi-note-4/how-to/guide-how-to-change-mac-address-mido-t3773026
(Again, be sure to only use Mi8 files) DO NOT use a QCN from another device.
Here is another guide that has illustrations, again use your own files for your device, Otherwise the steps are identical, I have completed these steps myself on other devices : http://en.miui.com/thread-348525-1-1.html
One last final option that I would suggest trying before using QPST
Did you happen to make a recovery of your phone, after initially installing TWRP for the first time?
If no, search the web for a full stock recovery

You may not have seen the post I made earlier here: https://forum.xda-developers.com/showpost.php?p=79802367&postcount=11
If these things do not work come back here and report what happened and I will stay with you until we resolve the issue, there is always something else to try.
I have successfully solved similar issues on other devices, the issue here is possibly a permissions issue due to encryption, Read the post above and make sure that you use the version of Twrp that is linked on my Mega drive. That version has no problems with encryption, while many versions of Twrp have issues with decrypting. Plus, that version allows the option to select and restore each partition ( There is a lot!)
Check this post later, I am going to edit this post, and add a link to the Persist Image from the latest Global stable Rom. This will be an alternative and maybe better solution than using the persist images that I uploaded to my Mega drive.
UPDATE EDIT
Okay, I created a folder on the Mega Link called Method with a TWRP flashable persist image >>> Install the Official Xiaomi EU TWRP English version ( The one on my Mega Drive) Boot to TWRP, Mount the persist partition > Choose Restore and install to persist> Forget you WIFI and rejoin, it may and will probably work for you.
Three Options if it does not
One
First Option requires fully wiping your device, so back everything up
Assuming that your Device is a Global Device
Download this Fastboot Rom : http://en.miui.com/download-346.html Download the Full Stable fastboot version and not the Recovery version.
Unpack the Rom, place your phone into EDL Mode - This Rom comes with the Fastboot flashall script, it will fully restore your phone to the a Stable Rom and Overwrite every partition., this is as good as using Qfil to unbrick. In fact I recommend this over Qfil. This should definitely work, as long as your issue is software, and I am certain that it is.
Two
You are too afraid to wipe the phone and would rather try something else first, since you would need WIFI to restore your Google Services and Mi-Cloud.
No worries, here is a QPST alternative that has worked for many people, you basically create a new Mac address by following the steps in this thread, read the comments, it has worked for many people and it may save you time, and its not as difficult as it may seem.
This method has worked for people with WIFI Authentication issues.
https://forum.xda-developers.com/showpost.php?p=70408778&postcount=9
Use this tool to generate a Mac address to use for the above linked steps.
Three
IMEI Repair
http://en.miui.com/thread-260943-1-1.html
Note although, you may not have issues with data or with calling, this solution ay still be relative. But definitely try everything else first, and leave this as a last resort.
Let me know, if it works, and if it does work , change the name of the OP "Solved" at the end. this way others can benefit from the thread
Update,
I just found another, much easier method of restoring the persist partition
Use Google translator and follow instructions here Then go thank the_virus_ua
Note you do not need to download the files on the link the file that I shared on the earlier post will suffice

hello dear, i'm sorry for the delay, i had some urgent work out of my country that why i late to answer, now i'm in my country and i started to apply what you wrote, but when i tried to flash twrp the on your reply i got black screen can't boot to twrp ( i think i made something wrong because i extracted the zip file and flash only twrp img through cmd fastboot ) please correct me or give another twrp img .
i read some comments on google that there is a risk to lose imei or something else, if that right how can we making a back up just in case
i hope to get your answer soon, and thank you sooooo much
anyway, i tried at my own risk, that's what i got in twrp ( see image ) then reboot to system but still have the problem ! no wifi no bluetooth !
** i tried factory reset too, not helping.

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.

"Trying to flash" , what exactly did you flash ?

Why dont you flash TWRP followed by ROM of any choice ?
NV normally contained in EFS partition, which can be backed up and flash from TWRP and QPST.
But again, your description is far from clear for us to help you.

When you flash using TWRP, did you actually managed to boot into system ? Or it stuck in recovery ?
Where did the nv corrupted notification appear when u were using TWRP ?
Prior to facing this issue, what you actually did ? I mean, did this phone work before ? Before you start getting this error, what you did, what you install, what you flash, what you delete ? Or did it just suddenly happen with nothing modified ?

This is absolutely not a issue, that requires using Qpst
You simply need to wipe data and follow the on screen prompts. (You will lose all data on your phone.) However the phone will work again.

Sorry that you are having these issues, But my comment was based on the photo that was posted on the OP. Typically formatting is the resolution. If you no longer have that screen available, you should contact an authorised repair center to fix it for you.
Otherwise If the phone is bound to your account, you could try what is listed here: https://www.mobilerdx.com/2019/02/xiaomi-mi-8-test-point-boot-xiaomi-mi-8-into-edl-9008-mode.html
Scams or Actual Fixes?
I have recently read about supposed hacks that according to a couple of Chinese BBS sites, has worked for some that require buying a specialised Jtag programming tool which cost about $60, that you use along with altered versions of following files: prog_emmc_firehose_8909.mbn.elf, mi8 persist image, rawprogram0, frp and a patch file. All of which that can all be obtained from here: https://romprovider.com/2019/09/mi-account-remove-xiaomi/ ( UMT Download)
Supposedly Chimera is another option: https://chimeratool.com/en/docs Again I have not used any of these tools with the mi8, I am merely sharing what I read about recently.
By the time you have spent the money acquiring the tools, it seems that you are better off just mailing the phone off to be repaired by an official repair center. Here is a web page that provides a list of official repair centers : https://www.pinoytechnoguide.com/2014/06/xiaomi-service-centers.html
Good Luck and try anything mentioned above at your own risk.
Edit: Have you tried the Flashall.bat method?
That should work since you are seeing the com port.

root cause of your issue is that you play with wrong qcn and messed up the nv,
wince you cant plugged to qpst, you need someone to make EFS backup for you torestore from twrp
You can restore phones imei if your bootloader is unlocked but only 2nd sim slot will work
How can I do this? Can you help me please?

Dear All,
While trying to install MIUI 12 Beta , I Lost my IMEI
Installed ENG Firmware which allowed my to edit the IMEI using the Maui META ver 10.1816.0.01 but due to corrupted NV Data the phone isn't booting
Anyone can backup and share the NV Data file ?! i found one online but unfortunately it has a password and can't unrar it.
Your support is much appreciated to guide throw fixing this issue.

You need backup EFS and Modem via TWRP first(better with OrangeFox). After you need Magisk first and some manipulation with QCN file via QPST. I will write it later

Maui Meta is for MTK cpu phones. You need QPST
Note 8 Pro is MTK Device
