Mi9T Pro no IMEI, no sim card signal. - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

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.

[Q] Help with imei null/baseband unknown (I have read so much but still stuck)

Hi,
I don't know why this happened. My phone is rooted but just randomly stopped working. It wasn't because of any flash. All I had done was root it about 5 months prior and was still on stock firmware. But now I have no signal. Here is what I have done.
1. Bought new sim board.
2. Flash the parambin file.
3. Tried to the qpst method to use nv reader to manually enter my imei. But the drivers won't work. Always has an ! point next to devices in device manager. Read, could be because I have the international version.
4. Tried flashing 2-3 other modems.
5. Updated to 4.4.4
6. Flash a file EFS_N7100XXND3_KH435987_REV05_user_low_ship to supposedly reset imei. Now I am just in factory mode.
7. Bashed head on desk.
Phone is out of warranty and there are no service centres near me. I really don't want to buy a new phone because I am saving for baby stuff.
Thanks in advance,
Tried efs pro,
It backed up efs, but on restore odin flash fails and soft bricks phone.
Try CM?
Why you don't try CM11 ROM? You only need to replace the bootloader, all well explained here:

[Q] Urgent help likely hardbrick D:

Hi guys I have a problem, I had in my hands a p7 of an old owner who does not know how he had cleared the imei and the cell did not take more, never mind if it could not restore it I would have used only with wifi but last night in an attempt to insert a hypothetical backup imei think I damaged part of the system and the bootloader because now the phone in question after the restart does not turn any more, and the LED flashes twice green then red twice and twice again green
Any key combination I try not do anything and if I connect it to the PC is detected with an unknown device name in Chinese ._. how can I rearrange the tuttooo ?? you help me prrgo T.T
thanks in advance to everyone I apologize if I had to put it in the post modding but I'm not sure where it belongs thanks
No one can help me?? D:

Depends on how you were trying to restore imei. Describe step by step what have you done?
i've use 5iromtoolbox on my p7 with root and flash a corrupt imei backup (i think it was of another huawei phone) i don't think it can be bring at hardbrick :'(
P7 keeps imei in other partition than 5iromtoolbox makes backup of. Shortly, if you could make backup with this tool before and then try to restore it, you were just reflash some partition without any affect on imei but and without any consequences for device. But you have flashed partition from absolutely other device...
Blinking led means that some partition is corrupted or even maybe partition table. If it could be some partition that can be reflashed via fastboot, you could have a chance to unbrick it. But it's not.
Now the only way to unbrick it - is full reflash of whole memory using some manufacturer's hardware tool. So you're right, it's hardbricked.
Bring it to service. But I presume they will you offer replace of whole board that is comparable with price of the new device.
yes...there isn't no solution to flash new partition unless hardware flash tool? or ther is a guide to flash it (i think no)?

"Trying to flash" , what exactly did you flash ?
How do you flash it ?
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 ?

Boot up to the Android logo and then return to recovery.
I flashed a room and lost the imei, I tried to recover with a qcn I found but I must have done something wrong.

You gonna need to ask someone to backup their QCN, take out the imei info, give it to you, and flash it using QPST.

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.

Hello, thank you for your answer, the mother is not linked to my account I disconnected to do the experiments. in my country i don't have a xiaomi assistance center, i get the error missmatching image and device.
There is no other way to unbrick without buying these tools so expensive that you mentioned

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

If you didn't backup your IMEI before you lost it, probably you will never can recover both of imei.
But, you can recover one of them.
You need to write the IMEI to any (newer) device that allow imei writing. (Redmi Note 8 Pro can does it.)
And then, making the imei 1 as empty/null and into imei 2 you can write your new imei.
After it, you can backup the nvdata from that phone and restore it to your device.
So, you will have only imei 2. If you try to write imei 1 too, your device will get nvdata corrupted.
Good luck.

If you lost your imei, definitely you didn't make a firmware upgrade, but a format all.

Yes, you can.
But you need a sim card from an operator that doesn't require the imei for using its service.
And obviously, you need your baseband intact.
If you try a sim card from an operator that requires imei for using its service, the sim card will not be registered.
If you want to restore the state of UNLOCKED BOOTLOADER, you need to follow this guide: https://forum.xda-developers.com/t/...omi-redmi-note-9-xiaomi-redmi-10x-4g.4220013/

No. It will never write or recover your IMEI.
Accidently got the drivers working. Then i tried using maui meta and sn write tool to fix imei but i got errors. For example maui meta says "Write to target failed" and sn gives something like timeout error. Never felt that close...

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.
