Mi 9T - no internet whatsoever - Redmi K20 / Xiaomi Mi 9T Questions & Answers

Hello,
I had some problems with my newest stable EEA rom (Find my device process crashing instantly), so I had to flash a new official EEA Fastboot rom. The device seems to be working now, but I cannot connect to internet using ANY means. The wifi does not toggle on and the sim card is not detected. From what I can gather, this seems to be a persist.img problem, but what can I do to solve this?
I found this guide (https://forum.xda-developers.com/mi-a1/how-to/tool-persist-resurrector-v1-0-0-0-t3781095) for Mi A1, but can I use this here? Any help would be greatly appreciated.

Try flashing stock rom with miflash

MI A1 worked 3 days

Hi all,
Last week i received my new MI A1. IT worked perfectly during 3 days, with 2 OTA updates to Android 8. (December and January OTA i remember)
Then, one night my MI A1 just shutdown itself without doing anything (i was sleeping)
And in the morning i tryed to reboot it but i had everytime a freeze and reboot when it asked to enter my PIN CODE. (i tryed without my SIM it was the same, big freeze and reboot)
Si i went to the MI website (xiaomifirmware.com/roms/download-official-roms-xiaomi-mi-a1/) to download the XiaoMiFlash Tools and the ROM (Android 8.0.0 Oreo (OPR1.170623.026.8.1.10) | Fastboot)
It worked to flash the MI A1 but i cannot start the phone, i had the Screen ENCRYPTION UNSUCCESFULL
When i clicked to Resert the phone, it reboot and came to the same screen. (I can host a video if ou want to see)
I've tryed to use FASTBOOT Unlock / TWRP 3.1 to wipe the system but still the same.
Do you have any idea please ?
Thank you in advance for your help

Can you try with a different firmware? Android Nougat?
Hi,
I've tested with Nougat (tissot_images_7.8.23_20170823.0000.00_7.1_61cf97d794) as flash and lock.
and that doesn't work. Still in like a bootloop.
i've tried also to go through twrp 3.2.1 but a a little bit lost.
Which FULL ROM do i need to take as ZIP file in TWRP ?
Also, do i need a SD CARD to completly reinstall Android ?
thanks in advance.

Can you repeat your question about twrp?
You can try to flash lineage os 15.1 with latest twrp-oreo and see if that works.

Nope. Lineage ROM can be stored in internal storage and flashed. Also, if you aren't able to solve the encryption issue, I suggest you to go to your nearest service center and get help. They do it for free, even if you're rooted or modified the system.

Thanks for the answer.
I cannot go to service center because i'm in France.
I've tryed to flash Lineage15.1 but doesnt work.
May be an idea, i've seen in TWRP that i don't have a cache partition. Is that normal ? If not, how do i create it ?
Flash your device from edl mode
If doesnt work it seems that your emmc is faulty
Many huawei phones with faulty emmc shows such this encryption failed message and by changing emmc become functional

- Then, enter fastboot and flash stock android 9 rom with this mi flash tool beta. Find in this link. (mirom.ezbox.idv.tw/en/phone/davinci/)

Mi 9T Soft Brick ? Antiroll back need help

Good day i have a problem with my mi 9t. I have installed the miui 11 eu version on my phone and i was using it for a few weeks. I have decided i want to go back to miui 10 global but when i go to flash the rom with mi flash tool i get antiroll back error as seen in the image on this post. I have tried to install via TWRP chinese recovery but the phone shows the logo for a few seconds and then goes straight to the TWRP recovery automatically. I tried installing havoc os pie still same problem. I was reading up about the anitroll back that the miui eu has and i think that the phone is soft bricked because i tried flashing via twrp with anitroll back on my phone. I did the anitroll back test to get the index and i have a antiroll back index of 1. If anyone can help me with this problem or have the solution please give me some help. Thank You
I am able to get into twrp recovery but any rom i flash just reboots back to twrp recovery
Ok I fixed it I just flashed back the miui 11 eu I was using before and it boots up but now I want to flash the new miui 11 global but I'm afraid it may brick again. Only one way to find out.
Have a same problem, what version eu rom work in your MI9T

"antirollback" warned by miflash even when using the latest 11.0.4 Global ROM

"antirollback" warned by miflash even when using the latest 11.0.4 Global ROM
Hi guys, I have made my decision to back to the stock firmware since Google fortified their detection for unlocked BL mobiles. However, I ran into a very strange situation when attempting to flash the stock ROM using miflash it stops to go further and displays "antirollback check error" under status.
Does anyone what could be the reason causing this?
I have checked the firmware files and redownloaded to confirm it is the latest version, no luck.
EDIT
NVM, I found the answer. It was the location of the miflash folder. It successfully flashed the stock ROM without any problem after putting miflash folder under C drive root directory.
What was your previously ROM? I'm on latest .EU weekly and also considering going back to stock Global.
In case you were on .EU ROM, how the Global ROM is comparing to .EU nowadays?
Now about Miflash, to go back to 100% stock I have to check that "clean and lock" option right? Or is there anything else to do?

The system has been destroyed

POCO M3
It started when i was trying new roms and unfortunately gyroscopic sensor (auto-rotation) and auto-brightness stopped working. I think it was cr-drod android 11. i tried installing all the roms via Mi Flash(.tgz) or Mi flash pro(.zip) none of it fixed the sensors i mentioned above. None of it was working i installed ubuntu touch it didn't fix it all but what i could i do init was
Code:
sudo rm -rf /
and then flash mi rom again.
well now phone is bricked and bootloader is locked i try both Mi Flash(.tgz) or Mi flash pro(.zip) with all the roms available online (Global,Turkey,India) from official websites i used to recover.
Error: Sorry, flash to this stable version is not allowed.
What happened exactly ?
MIUI flash pro does recovery IMEI and shows current installed MIU version.

The only way is flash through EDL mode if you are with locked bootloader
