9t Pro bricked, can only access fastboot HELP

[SOLVED]
I need help I just bricked my phone and can only access fastboot.
I just unlocked my 9t pro to install a custom rom and followed the steps of this video ( can't post link but it's called: Redmi K20 Pro / MI 9T Pro - INSTALL Pixel Experience ROM Official | Android 9 Pie)
I managed to install twrp, made a backup of dtbo, boot, system and data and then wiped dalvik, cache, system and Data. After that I flashed DM Verity Force Encrypter and proceeded to flash havoc-os which gave me Error 7. I figured I might need to reboot the recovery, after doing so only fastboot comes up anymore. I cannot access twrp and have no OS installed. Please help.

If bootloader unlocked, you could use MiFlash to flash stock Rom

This is the problem with random YouTube videos, they don't always give good advice.
There is no reason to back up dtbo, unless you are going to install an overclocked screen refresh rate mod.
There's no reason to wipe system.
There's no need to install DM Verify Force Encrypter, unless you know what they are for and you choose to disable DM Verify and/or permanently disable encryption.
Go here https://xiaomifirmwareupdater.com/archive/miui/raphael/
And choose the fastboot ROM for the version you want to install, then flash it in the Mi Flash Tool.
When flashing you MUST change the flash option at the bottom of the screen to 'clean all'. If you do not change this you will brick your phone (worse than it is now)
After this you can start again. Your best solution to flashing is to search these forums. There's many good guides here

Root via magisk doesn't work

Hi,
I'm on MIUI Global 12.0.4.0 (QCREUXM) rom, and my bootloader is unlocked with official Xiaomi tool.
I tried to root my Redmi 9c by modifying the boot.img file with magisk, and flashing it via adb.
It resulted in bootloop. So I reset back to the original boot.img, and I'm still rootless...
Does anyone know how to root this phone ?
There is no TWRP for it right now.
Thanks for any help.
BTW, is it normal that modified boot.img is much lighter than original file ? (11Mo vs 65Mo)

I am facing the same result, probably the reason is that the device is SAR - System-As-Root, therefore patching boot.img aint giving root previliges and flashing causing bootloops.
Moreover modiying the system.img and flashing it wont give you root ethier.
You can try modfying and flashing the recovery.img while wiping your data as dsecribed in magisk site but every time you reboot, you need to apply the same combo buttons to enable the magisk root.
All we can do for now is to wait for a custom recovery that will probaly never be arrived or im wrong.
BTW: the patched img is supposed to be small as what ive researched, magisk repacker is repacking and compiling it to a smaller img.

Flash pachedboot.img then vbmeta 256 bites file

Redmi 9c not rooting via magsik patched boot img

After flashing boot.img file flash vbmeta.img file it will prevent it from bootloop just Google vbmeta.img download it and flash it through adb tools after flashing magisk modified boot.img file
To flash it in adb type flash vbmeta vbmeta.img
I have successfully rooted my redmi 9C with this method and no bootloop issue

Question Install Xiaomi EU ROM on Redmi Note 10 Pro

Hi! I need some help! I would like to install EU rom on my Redmi Note 10 Pro phone, but I do not know how to get started. I've already opened bootloader and installed Drivers, ADB. I should install TWRP after this, but I don't know if I should install disable dm verity forceencrypt. In principle, you don't need disable dm verity forceencrypt for TWRP 3.5.2.0. Someone could write down the steps on how to install the EU rom? I need a fresh guide. Please help!

no need to flash anything
make sure you have the latest twrp (nebrasy-3) and just;
- flash ROM
- format data by typing "yes"
- reboot
flash magisk after the first boot if you want it

Question [Solved] Mobile won't boot anymore ! :/

Hi guys, i just flashed (with a light wipe) the last rom for my Xiaomi Mi 11 Ultra (obtained on the update section of parameters) and i first lost all my config.
So, i decided to restore the backup i made just before flashing and here is the drama, it boot directly into TWRP and i can't seem to find my storage anymore (tried file manager)
TWRP also tells me that no OS is installed, please help, i'm desperate
I think the first step is to recover access to internal sdcard, and maybe then i can restore a backup
Thank you !

simply, Fastboot and install official rom using mi flash tool.
thats one of the penalties you'd pay of installing eu rom.

Thank you very much, sir !
Will try this and post the result, maybe with a little tuto if it's not already everywhere ^^

So, tried 5 times and not once a good result, the better i can obtain is 12.5.7.0 global working, flashed with xiaomitool. TWRP ok, and i will try Magisk next.
Every other tries solded by an sdcard/os/data loss T_T
That's a mystery. I ran on 12.5.17.0 all fine before this incident and i cannot get it work anymore :/
I obtained rom from https://androidfilehost.com/?w=files&flid=321331
TWRP from https://androidfilehost.com/?fid=14943124697586336381
Also tried this method again (this was my first method and it worked like a charm till this 12.5.20.0... )

forum.xda-developers.com
The problem with global is it seems to be greatly outdated (patch from 2021.09, that's a huge security risk to be months backward nowadays, let aside bug correction, new functionnality, etc)
I can't seem to find a more recent global version (updater within settings tells me there's no more up to date version).
Do someone have an idea, please ? :/
What i'm doing :
1. put device on fastboot mode
2. launch xiaomitool and flash 12.5.7.0 global rom
3. reboot into fastboot
4. launch xiaomi unlock and unlock device
5. boot TWRP with fastboot boot twrp.img in cmd (command returned all ok)
6. into "soft" TWRP, One Key Inject TWRP
7. into "hard" TWRP > install and give it the .zip rom file
8. after the rom installed, all broken again :/

Hi,
there is no TWRP-ROM available for the Ultra - it's still in fastboot-ROM phase.
Flash via fastboot. Unlocking is just needed once until relocking with orig. ROM.
(Optionally) Copy boot.img from ROM-folder to phone.
Use Magisk to patch boot.img
Flash patched boot.img to boot_a and boot_b via fastboot.
Wait until TWRP-compatible-zip's for the Ultra to begin to appear.

Thanks for that ! ^^
That sure seem a simple task
You're telling me that i can, from my 12.5.7.0 global, patch the boot.img (90mb) from the 12.5.20.0 eu with magisk, flash this with fastboot and that it will work ?
Seems too wonderfull to be true XD
EDIT:
My bad, you said "optionnally", not "alternatively"
So, i'm stuck here, i don't know and can't seem to find the fastboot cmd to install the xiaomi eu rom in .zip format
Do you know it please ?

In all the 11 Ultra A12 weekly EU ROMs, the format is fastboot only. Just extract the .zip file to a folder on your desktop, connect your phone in fastboot mode, power on and vol down and then click on the update bat file. If your coming from a different branch, click on the update and format bat file ( the bat files will be in the upper most extracted folder). It is a simple as that .
