Question No mobile data after miui update. - Redmi 9 Power / 9T

Hi,
Does anyone can help me with my problem?
I have a redmi 9t (abouth 8 month) and all worked fine until a miui update.
After the update i cant connect to a network. Only wifi works.
I have tried everything i could find online to try to solve my problem, even factory reset. Nothings work . So i tried to unlock the bootloader to try to flash a costum rom, but becouse i have no mobile data i cannot unlock it becouse you need mobile network to do so.
Contacted local miui support, but they could not help me becouse of the regional boundings.(belgium over here) Tried to contact the online shop where i bought my phone. But they are not online anymore. So my question is:
Anyone now how fix my network and or unlocking my bootloader without mobile date.
I'm getting desperate .
Greetings, just a man who want to use his phone to call again.

OK. First don't worry. You can flash your mobile without Unlocking Bootloader. If your Phone is "lime", It is based on Qualcomm Snapdragon CPU. You can try the QFIL Tools By Qualcomm Official. You need to have your phone in the Deep Flashing Mode. And Download the Official MIUI Image to flash it (I am Chinese) so you can go to the link here and download the ROM. flashing it with QFIL.
Good Luck to you.
2022-5-23 I'm using an Redmi 9T with MIUI13. IIf you still don't understand, you can ask me again.

Missing WiFi MAC and IMEI - Mi 9

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.

local update

Hello everyone, being new to xiaomi devices, i would like to ask about updating. So my mi8 is currently on miui global 11.0.2 (PEAITTI) which i suppose is an italian variant. My problem is that the updater does not find any new updates despite the fact that there are. So I searched for manual update and found this https://c.mi.com/oc/miuidownload/detail?guide=1 . My question is this is local update used for every factory rom regardless of the area and without the need to unlock the bootloader? And is fastboot update for every rom?
Extra quetion: Do i lose something by unlocking the bootloader except the warranty? (asking that coming from sony device)
Thanks in advance.
I have some experience installing MIUI and I advise you not to "mess" with the bootloader.
There is a condition that your device goes into "Brick" mode. See- https://forum.xda-developers.com/mi-8/help/undo-fastboot-oem-lock-t4126427
by unlocking the bootloader You will be exposed, to some extent, to intrusions into your device by hackers.
The safest situation is to only update the system by OTA! especially that you have an "Italian" MIUI system (which appears to be global).
On the other hand, if you have prior knowledge and experience, you can update your system independently, even though there is a risk, by flashing through software you can find on the network.

Have you found a solution? I have the same problem. The latest version is 11.0.4.0QEAMIXM, but it cannot be installed by updater because "the current ROM's network carrier type is different from that in the Recovery package".

I haven't searched further into the subject due to lack of time in the current period and I'm fine not having the latest software as long as the device runs without problems (don't fix it if it ain't broken).
After reading your post again, I guess the "original" rum installed in the mitsosJL device, was installed by the seller who sold you the device.
You should first check if your bootloader is locked or open. (See https://gadgetmeetsguy.com/how-to-check-if-bootloader-is-unlocked/
If you decide to "unlock" the bootloader and install an update on your device, you will find many how-to guides.
I received an update via OTA for my Xiaomi Mi 8 device.
Update Name: 11.0.4.0 QEAMIXM Global.
There are not many changes since most of them are suitable for certain "regions", like China-India and some other countries in the world.
In any case, my recommendation of 02.07.2020 is still valid.
Good day to you.

No Wifi and Sim Card Service

Hello guys, so about 4 months ago I flashed HentaiOS, and after that I flashed wrong type of kernel.
After that I restarted to the system and my Sim Card and Wi-Fi didn't work, My phone doesn't find any Wi-Fi and it doesn't recognize the Sim Card. Is there anything that I can do? I live in Iraq and I brought to Xiaomi Iraq and they said that I have to change the motherboard, it costs 120 dollars to repair. Is there anything that I can do without changing the motherboard? Thanks for answering

Question IMEI gone

Hi guys, I'm in a very big trouble, since I was trying to rollback yesterday from A13 Oxygen 13, in a converted NE2110 Chinese model flashed previously with NE2115 Rom, I was having ridiculous battery life with the rom, so I want to test the European NE2113 rom, I've download the NE2113 Rollback package and applied with the local update apk provided by Oneplus, the procedure was apparently sucessfull, but SIM isn't recognized when A12 NE2113 rom booted, I've thought its a band relates problem, so I've flashed black the NE2115, but stills the same, I've get in to the IMEI numbers, and both are NULL and Baseband is blank.
I'm in Ecuador so it's absolutely impossible for me to sent the phone to Oneplus Repair services, and even if it was possible I doubt a lot they can take the phone, because it's bootloader unlocked.
If anyone have an idea about something I can do, I'll really appreciate that, it's an expensive phone and I've put a lot of effort to buy one trought and auction sale and even played to import from United States, so if you think there any hope available please share with me, I've read the one post here with someone who still needs to repair the IMEI seeing it's impossible for now, but at least I have to try to restore the phone, I can't have a media player unusable SIM phone of almost 700 bucks.
