Missing WiFi MAC and IMEI - Mi 9 - Xiaomi Mi 9 Questions & Answers

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.

HELP - Mi3 with no IMEI

Hi,
I've bought a new Xiaomi Mi3... it came with MiuiV6 installed, but it doesnt have IMEI!!
The IMEI on the back of it is OK, the phone is an original Xiaomi Mi3... i belive that the seller (ibuygou.com) made a fail flash of Miui V6 and the Imei was lost in the process...
I've tried a hard reset and nothing... i've flashed the lastest Fastboot via MiFlash.... and the lastest 5.2.13 Multilang ROM... i had problems with Wi-Fi connection and after this they were resolved... But the SIm recognition (does not recognizes it) and the IMEI Loss is still happening...
Anyone can help me?!? ibuygou.com is on spring festival hollidays
Via QPST i've downloaded the 00000000_0.qcn File... but once i don t know what is the bricked/crashed IMEI how can i change the Hex code for the correct IMEI?! is there any way to find out what Hex code i have to replace?!? so i can restore the 00000000_0.qcn File with the correct IMEI?!
Regards

mi3 invalid imei and baseband unknown

Hi, after flash a rom, my mi3 doesn't detect baseband and my imei invalid. I tried to flash miui using fastboot (clear cache, data, everything using MI Recovery. Flashed dev global, stable and local roms) but still not fixed. I also tried using QPST but the memory dump is too small so I stopped. Anyone knows how to fix this? Thanks
Do you have a backup ROM using CWM? Because I had this problem before but it was fixed by restoring my previous CWM back up.
Have you seen the thread on MIUI.com about fixing IMEI on Mi3?

Ty for reply. I have done that many times but it seems that my nvram is corrupted. I dont know how but all the settings and configurations are empty including imei number. I flashed more than 10 times stock rom with different method and my baseband is back. Still the imei is missing. Then, I try to fix the imei by looking at the nvram memory dump. I injected my old imei (from mi3 service card) then the imei is back. Somehow, still no services.
I think that my nvram is badly corrupted due to random error in flashing. This is my first time having this issue because other phone (Sony Xperia) i have can easily fixed by flashing the stock rom. If only I have the hex file to compare. By the way, the memory dump is about 150kb. Too small isn't it?
Hmmm. . . . . Seems you need a really hard flash on that. You'll need to go to a service center for that.
try wiping cache data and then flash rom.

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.

loose imei, not detect sim card

Hello,
I'm french, excuse my langage...
I have 2 note 8, an N950F (single sim) and an N950FD (double sim). I specify immediately that the 2 have already worked and that I have only one sim (one being for me and the other as a gift for my wife lol)
- On the N950F, install via odin 3.14 of twrp 33.1.2, then hadesrom 12 then magisk 20.4 => everything is ok
- Purchase of the N950FD, hassle with installing twrp because I had to put my sim in it to change the time and have access to the usb options, in short, it works, then same as hades and magisk => everything is ok
I have well customized the N950FD, I made a full save (all partitions) with twrp and I said to myself I do a full install on the N950F ...
At the time I did not watch out ...
I calmly use the N950FD and then, I still hack the N950F, I install other custom roms to see, lineage 17, etc etc and all that I do it without sim, with the dex dock connected in ethernet, in me saying that when I'm done, my wife will just put her sim there ...
And then something bothers me, it's a small prohibition logo at the top left instead of the network. I tell myself that this is normal because I did not put a sim, so I take that of my N950FD and there bah it is not recognized ...
I do not panic, I tell myself that I made a false manipulation, I wipe, I reinstall hadesrom and same concern, I take another custom rom and same concern ... I redo a full install with twrp and same concern .. .
I take a stock rom (the last, then the first, always in 4 files either with the csc or with the home-csc), I flash with odin 3.14 and 3.13 and always the same problems, the rom remains blocked on the screen samsung, the first with "samsung note 8 powered by android". So I tried the last rom with 3.14 and 3.13 then the first and still the same problem, it does not start (I waited 5 minutes roughly) despite the wipes ...
Since I no longer have twrp, I reflash, it works, I tell myself that the custom was still installed and I reflash via twrp hades (I tried the stock rom file but it didn't work) and again same concern, the sim is not recognized ...
I try the flash of the hades kernel, it works but the sim is still not recognized ...
When I go to the phone * # 06 # I do not have imei, but a black screen, when I go to parameter / connection / sim card manager => black screen with the message "com-android-phone does not respond" ...
I looked a little on the net, but nothing conclusive, I specify that all my files come from XDA but that given my English I prefer to try to find an answer in French ...
I do not have a backup of the N950F it would have been too simple, I tried another sim than mine but ditto it is not recognized and before making a tablet I would like to try everything to recover it. ..
It would seem that flashing a stock rom solves the problem ... But as said above, my phone remains stuck on the samsung logo despite the wipes
I still tried other things like just flashing parts of a stock rom but I still have the same problem ...
I also tried the flash of a stock with the extra pit and the nand erase and distribution options ... and similar, no start ...
I even reinstalled twrp after a stock, save it, "mix" it with another backup I had (efs and modem from the stock and the rest of the custom) but then again, it doesn't work, such reboots well but still no network access and no recognized sim card ...
Finally, I looked at chimera tool, but no tutorial in French so no way to see how it works or if it will meet my need ... taking an exclusive samsung license on chimera does not cause me any concern IF it allows me to do other things than what I have already tried ...
I also looked at the prog to change the imei because there is nothing left, not even 0, no no, a black page just like when I go to the sim card settings, I have a black page. ..
I also flashed several custom roms from different countries but it didn't work ...
By cons I observed that I had the location for 2 sim, still inactive ...
How to put the note 8 in single sim and recover imei and then the network ???
there, I block ... if you have ideas I am taker, thank you all ...

If you didn't take a backup of your /efs folder which is where all of the phones important information is stored such as your IMEI then you are screwed because you can't flash any other phones EFS FOLDER.. However if you have a backup efs folder, restore it.
the concern is that I do not have a backup of the efs file ...
is it possible to put an efs file of another note 8 n950f and where to find this file on the net?

MrMike has already answered this, you can't share or use any other EFS.
The fact you can flash a custom rom and it will boot tells me you don't have a hardware issue, try flashing stock again as this can sometimes fix the EFS file, it has done for me in the past and a few others users. Although I can't tell you why you get stuck after flashing stock, this is the best way for you to hopefully resolve your issue as you don't have a EFS backup.
Except by flashing a stock, is there a way to restore the n950f to factory condition?
because with odin, if I flash the last stock, it does not start even if I make the wipes and if I try an old stock, odin blocks ...
can the chimera program allow me to find an original n950f?

Not that I am aware of, I am only aware of restoring by flashing stock with Odin or by using Samsung smartswitch.
You can't flash older filmware than what is already on the phone, that is why Odin is blocking that, but when you flash the latest filmware does Odin give you the green pass?
I am not familiar with the Chimera program so can't speak on that.
Yes with odin I have the green pass, but then the note 8 does not start, it remains blocked on the logo, even if I do the wipe ...
I even tried to save right after with twrp and recover the efs but it does not work ...
If I find a broken Note 8 can I recover the efs file by saving it and then putting it on my own?

Thanks for your help, how to start it in stock rom?
I specify that it starts in custom rom ...
the first photo is before the installation of the stock rom with odin, the second is at the end of the installation (odin ok, pass in green), the third is after the restart which has not worked (blocking on samsung note 8)

Could you please explain to us all in here how you're going to fix his /efs folder when he never made a backup of it.. Where are you planning on getting him an /efs folder that held all of his phone's information when he accidentally deleted it?

By root device and download Root Explorer, browse to the efs folder the delete everything EXCEPT the 'FactoryApp' and 'prov_data' folders it should restore IMEI

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).
