[GUIDE/TIP]Failed fastboot flashing of stock ROM

I was on stock ROM (12.0.8.0 QJSEUXM) and noticed that v12.0.9.0 is out for some time already, but not offered by system to be installed. In the past with my previous phones when I wanted to "force" the update, I simply downloaded fastboot ROM, flashed it and re-rooted the phone. In a matter of few minutes I had up-to-date and working phone again. Today I tried the same with Mi 10T lite and it failed miserably.
Observed issues:
1. flashing script (flash_all_except_storage.bat) comes with CRCLIST and SPARECRCLIST commands which are either not understood by phone (fastbootd), or fail verification (fastboot)
2. after modification of script and removal of beforementioned lines, flashing completes, however phone stays in bootloop showing just Mi logo
3. using different PC, USB port, USB cable, fastboot version, fastbootd/fastboot mode, driver version, Mi flash,.. result always in the same non-functional phone
4. after booting to TWRP (fastboot boot twrp.img), internal data gets decrypted correctly, but TWRP reports issue mounting /odm
5. flashing different ROM version results in the very same issue
Fix:
1. Flash stock ROM (in my case 12.0.8.0)
2. If you receive an CRC error, remove 2 lines from flashing script containing words CRCLIST and SPARECRCLIST and re-run it again
3. Download recovery ROM (12.0.9.0) and put it to internal SD (you can do it in advance or through TWRP when the phone is already "soft-bricked")
4. Flash recovery ROM from TWRP & reboot to functional system
I noticed that fastboot ROM uses super.img, which for some reason isn't flashed properly. Recovery ROM flashes /system, /vendor and /odm partitions directly, which overcomes this limitation. If anyone knows why it happens and especially how to use fastboot ROM directly with no extra steps, please share it.

What error? You might need to modify your flashing script and remove lines mentioning CRCLIST and SPARECRCLIST.

For flashing you need to be in fastboot mode. If your phone is not detected correctly, most probably you have incorrect drivers installed (ADB instead of fastboot). Check from command line "fastboot devices" - you should see your phone connected. If it's missing, check your drivers in Windows device manager.

Might be easier for you to show the lines.. I removed only 2 lines, but maybe there are more with more recent ROMs.

I remove 4 lines but still have the same issue. I reopen MI flash tools, upload ROM again,and still showing the same error, I will upload pics later

I was using my phone normally, I left it charging and when I looked at it again, it would restart non-stop. It's a Xiaomi Mi 10T Lite, I held the power button, but it didn't turn on, it just came back to the bootloader screen, I didn't try to format it as I was trying to recover my files.
So I thought about unlocking the bootloader to get access to my files, I used Mi Unlock Tool, but it doesn't work. I still have access to my account phone number and email address. But I couldn't unlock by this method.
Please I need your help. Thank you

Show what error you get.
There are people flashing with Mi-Flash that always gives errors, but the phone still successfully flashed and bootup.
Some errors are saying the bootloader is not locked, but the flashing process are success.
Flash fastboot ROM can be even done with just double click on the "Flash all.bat" file from the fastboot ROM. All these programs are running those scripts which is already inside fastboot ROM.

everyone's problem may be different. I've been trying to install rom for two days. I tried all fastboot roms with miflash and xiaoMitool. I failed in all. I wanted to share when I was successful in this method. Anyone who wishes can use whatever they want.

Everyone's problem may be different, so still need to see what error encountered. Some people cannot use Mi-Flash because they accidently locked bootloader. In this kind of cases, even the tool you mentioned can't help. So still need to post what error encountered.
Of course. I put alternative programs so anyone who wishes can use whatever they want.
The tool you mentioned can only be used in Windows, but it also can work on non-Xiaomi phones like OnePlus, some ROG/Asus, ZTE, Nubia etc.
There will be from time to time some people asking how to do it on Linux or macOS, so they need alternative programs.

This worked for me on my poco f3. Was having issues with mi flash. Thanks for sharing

Question First time trying to install a custom ROM, ended up with a boot-loop. Don't know how to fix.

I tried installing Pixel Experience on my Poco F3 (using Windows10), for some reason I end up in a boot-loop.
Now I'm trying to restore an official ROM but the .bat provided with those just simply closes after typing Y (warning message) and entering.
Ofcourse, as a total noob would, I don't really have an idea what version was installed before other than I updated to the latest MIUI (through the phone itself) a week ago.
Kind of in a pickle here, phone unusable :x

I assume that developer mode is unlocked and the bootloader unlocked?
- Install mimimal ADB & fastboot in Windows
- remove cable between phone and computer
- turn off handy
- Run Fastboot CMD in Windows
- turn handy on with " POWER and VOL-"
- connect cell phone with computer
- in Fastboot CMD type" FASTBOOT DEVICES " (now you should see a number)
if no number appears there, the device is not recognized. Reinstall the driver, try another USB port and/or new USB cable.
If the number appears, download the correct fastboot ROM and install it with the MiFlashTool.

Yes I have.
Running the PixelExperience bat as Administrator causes it to close after launch, without any messages.
Running the MIUI bat as Administrator does exactly the same thing as without, shows warning, I type Y and enter, prompt closes.

I downloaded the minimal ADB & fastboot for Windows, ran the command and I can see a number for my device, so I'm guessing thats fine.

Then I downloaded the MiFlashTool (latest) and on startup I already get an error:
Pressing "Continue" removes the error dialog and then stays on the driver update screen with "waiting"

Thank you, I found out just a little after making the post. The Xiaomi websites are a real mess! There's a bunch of different ones out there, but most of them are out of date.
With that latest version, I managed to reinstall MIUI although the tool itself said it encountered an error. (I asume it failed to send the restart command or something like that, because after restarting myself I was greeted with the MIUI first use setup)
Now I got my phone working, I can't wait to break it again ;-)
Any suggestions on what Custom ROM looks the cleanest and works best at the moment?

How To Guide MiFlash 20220507 – Xiaomi Mi Flash Tool (New)

Mi Flash Tool is a tool by Xiaomi to flash firmware or Stock ROMs on Xiaomi devices.
The tool is simple yet powerful. The process for flashing any file is very tough but this tool made it very simple. Just connect the phone in fastboot mode and select the file and click on flash.
Clean all: Select this one before flashing to wipe everything from the device including storage system data etc.
Save user data: This can be selected when you want to keep the data untouched. But this is not recommended to use in all cases.
Clean all & lock: Clean all is the same as the above one but the lock means it will lock the bootloader again on the device.
Xiaomi frequently releases updates for the Tool with some new features. If the latest version of the tool is not compatible with the smartphone you’re flashing then try flashing it using the older version of the tool.
Keeping this in mind we have also provided links to download Mi Flash Tool (All versions).
Find MiFlash flash tool from the link given below.
MiFlash 20220507 (New)

How to use Mi Flash Tool
Download the Xiaomi Stock ROM or Firmware for your Xiaomi phone.
Extract the downloaded .tgz file using any extractor like WinRAR (remember the extracted location).
Power off your Xiaomi phone and then press & hold Vol down+power button to boot into fastboot mode.
Open the Mi Flash Tool on PC (search for it on the windows search bar).
Connect your phone with PC using a USB cable.
Click on the refresh button to check your device is connected or not. If it shows anything on the index it means that the device is connected.
Now click on select and locate the extracted firmware folder.
In this Tool, you will see three options below. Select clean all to wipe everything from the device, select Save user data to Save your content, or select clean all and lock to clean everything and lock the bootloader again.
After all these steps click on flash and wait for completion.
It will show the success message after flashing.
Done, this will automatically reboot your device, if not then reboot your device manually. The first bootup after flashing can take time so you don’t have to worry about it.

Nice and simply guide!
Few things to point out:
Instead of "stockfirmware.info" I recommend xiaomifirmwareupdater.com
On most Windows PCs, Windows Update auto-installs generic Android USB drivers, which should work fine.
On other PCs where the phone doesn't get detected, you can install the drivers from within Mi Flash > Driver.
Linux:
Linux already has the drivers. Mi Flash is not available on Linux, so in order to flash the Stock ROM in Fastboot Mode you'll need to run one of the .sh-script files from the ROM-folder directly, which requires SDK Platform Tools (allows you to do Fastboot and ADB commands):
Ubuntu (or other Debian-based distros): sudo apt install android-sdk-platform-tools
Arch-based distros: sudo pacman -S android-sdk-platform-tools
For a visual guide I can also recommend the YouTuber "munchy" who has covered pretty much everything in regards to Xiaomi Modding. e.g. How to revert to Stock ROM, How to flash TWRP / OrangeFox, How to update firmware, How to flash Custom ROM etc.

Question Phone rebooting Kernel Framework crash and DM verity error

Hi,
I have a 6 month old EU model of this phone which has started rebooting frequently and displaying a DM Verity Corruption Error, the MUI Ui log folder shows abnormal reboot kernel /framework.

This phone is running stock software and has never altered / unlocked / rooted.
I've tried factory reset from within the settings menu and restoring backup, I've also tried wipe and reset from the recovery menu and not using my backup or installing anything and it still rebooted after 35mins up time, the device is not hot not has it been dropped.
I've also tried reinstalling the latest firmware but could only get this to work from within the setting and selecting download latest package.
I tried to download the latest recovery firmware and copy to SD CARD, naming as update.zip and it did not try to flash when I used the recovery boot (power off and power on holding power and volume), I also tried from the settings, about phone, MIUI press it a lot and then under the dots choose select package but it tells me it's not allowed to install an unofficial package.
I've tried to contact customer service and had the 'thank you we will respond in 48 hours', I think something may have been corrupted on the last MIUI update and it's very annoying as it's my Wife's phone and my Poco X3 NFC has been brilliant.
I can't seem to find other way to try and clean install the software, please can anyone relate to these issues and offer some advice on how I may be able to flash the current software over itself , of course it could be a hardware fault but it seems too much of a coincidence it is since updates have been received.
