[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

How To Guide Different Method for Installing Poco F3 Fastboot rom

For those stuck in fastboot mode, I'm going to talk about installing fastboot rom by following a different path. I tried different methods because I was constantly getting errors with Mi flash. I can say that I found a 100% solution with the method below.
First of all, download and install the following files on your computer.
1: Minimal adb
2: Toll all in one
3: And drivers.
4: The fastboot rom you will use
------------------------------------------------
1: Extract the downloaded rom to the folder with winrar.
2: Run minimal adb. keep it open
3: Run tool all in one.
4: Connect the phone to PC in fastboot mode.
5: Tool all in one will see your phone. If it does not see it as poco, select it as generic and introduce it.
6: Choose to flash factory images
7: Choose xiaomi fastboot rom flasher
8: Select yours unzipped rom folder
9: Run flash rom.
10: Wait 5-8 minutes and finish.

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

I was unable to flash with XiaoMiFlashTool as it triggered the Anti Rollback, but the images i tried to flash were the latest MIUI fastboot files available (They haven't updated for aliothin since June 26).

The one above is the arb control which compares the anti in the phone with the anti in the rom.
I don't want to give you bad information, but I downloaded and checked all 12.0 and 12.5 stock EEA roms (my region) and they are all anti = 1 so I think we can flash them all. that miflash error should be a program bug. Let me know if it works

Nothing serious should happen, since you are restoring the rom you had before flashing the castom, the important thing is that you remember to select the check on "clean all" at the bottom right of the miflash program, because if you leave the check on "clean and lock" blocks the bootloader and then you risk the brick.

True, but I am just asking because this modifies quite a bit of files and I hope it doesn't mess anything up.

If you follow the instructions step by step, you should be fine.
1) Extract the rom;
2) Edit the .bat file as I told you above, delete only the selected one and nothing else.
3) enable usb debug on the phone developer settings;
4) open miflash as administrator and select the rom you need to flash;
5) select "clean all" at the bottom right;
6) restart the phone in fastboot and connect it to the pc;
7) wait for miflash to recognize the phone and make sure that "clean all" is checked;
8) press flash and wait for it to finish without touching anything.
9) it may be that miflash gives some other error, you wait for it to finish, unplug the phone and restart it if it did not boot by itself.
10) remember that the first start can take several minutes on the miui screen, wait without doing anything, if everything went well you should see the configuration screen.

Question [URGENT] Failed to mount '/system_ext' '/product' '/vendor' '/odm' (Invalid argument)

Hello, the error described in the title appeared when i tried to dirty flash the Miui 13 update european version for the Poco F3 on top of Miui 12.5.7. Before flashing the rom i forgot to mount some partitions, including the cited ones, giving me the error. Now i can't mount the required partitions, can't flash the old system nor the newer and TWRP says there isn't an OS installed, as such it goes into a bootloop.
Does someone know what to do?

No doubt you have, but just to check... you have extracted to .tgz file to reveal a .tar, which also needs extracting (i use 7zip) until you have a folder that contains the images folder etc etc.
Also, it could help having Mi Flash and the above folder containing the images in the root of C drive, rather than deep in the drive with a long title - eg D:\ANDROID\Xiaomi\alioth_global_images_V12.5.6.0.RKHMIXM_20220210.0000.00_11.0_global
EDIT: oh and be sure to uncheck the flash all and lock option in MiFlash (bottom right corner), or your bootloader will be locked after flashing...

I just controlled and it seems what i did while trying to flash the fastboot rom is completely wrong since i tried to flash the recovery version. I have downloaded the fastboot rom now but i will have to try to install it tomorrow

The rom was flashed succesfully this time but it still goes into the mi recovery when trying to boot. i flashed twrp to see if i could flash the rom from there and now all partitions can be mounted except for /data. When trying to decrypt it using the pin passcode it says Password Failed. is it because i also had the fingerprint and face unlock? When i still couldn't mount the other partitions I always used the pin passcode to decrypt storage. Has the passcode been changed when flashing with the mi flash tool? I don't have a recent system and data backup nor a backup of the internal storage so this issue is devastating to me, i want to save my data at all costs
EDIT: I tried reflashing twrp from fastboot and now I also can't mount the /cust partition with error "Structure needs Cleaning"

Perhaps someone else may offer some better advice, but as far as I can tell your original system is gone. Once you accept this sad fact, you need to flash fastboot rom using miflash choosing the option 'clean all' (NOT CLEAN ALL AND LOCK) to flash the system clean again, after flashing you can expect an error that miflash couldn't lock the device, this is usual. then your device will restart and take quite a few minutes to boot again. don't bother to flash twrp again yet, just the system running first

So i have to accept that all my data is gone? No chances of decrypting the data partition? I'll wait and see if someone has something that could work, if nothing else does i guess i'll have to accept the reality. Thank you anyway

I experienced pretty much the same thing as you in the past (i.e. 'failed to mount' and 'no OS installed' errors); unfortunately, the internal storage is most likely wiped. Happy to be corrected for your sake, but I am in agreeance with @reg66.

TWRP doesn't display the "OS not installed error" and before flashing the fastboot rom version the data partition could be decrypted normally with the lockscreen passcode. Does this mean that Mi Flash encrypted the data partition with a different key?

Thank you to @reg66 and @Sauceunny , I have decide to wipe the memory of the phone as i have deemed it to be too much work to save some chats and images while the most important files are stored as a backup. I will have to plan the next update or changing rom more thorougly next time.

Are you able to expand this tutorial on how to change partitions or on how to "update" msm so it uses a later version of OOS to unbrick the device?
The actual msm tool for OP9 Pro would install OOS11. But can it be changed to flash OOS12?

this tutorial only for how to extract partitions. android 11, 12, coloros, no matter.
for others can't help you

This part was empty for me:
Command "Fastboot devices" was working..

The tutorial in the first post is somewhat misleading. Fastboot is needed to flash back the partitions. In order for the partitions to be secured with the MSM tool, the phone must be in the EDL mode.
1. that means shutdown the phone
2. Start the MSM tool and press F8 on the keyboard
3. Press both volume keys at the same time and then connect the USB cable
4. Now the tool would have to recognize your phone and the partitions can be selected
The rest is well described in the first post.

I have a question, Im new in xda and I want to backup modest 1/2 and persist. In this post you can do it in MSM but I cannot see modemst1 or 2 in the partitions checkbox. They have another name? Or I cannot backup those partitions via MSM?

You don't need root to backup, but you do to restore the backup.

This is what my phone says when I open partitions backup
So that's why I want to do it via MSM like this post, but I don't know what partitions do I have to check in MSM. I can see persist but modest 1/2 I cant

Sorry for misleading you, other than that not sure how to get the images you want.

Ok so I made backups using this method like 2 days ago, if we ever need to restore them, how do we do it?

With partitions backup?

No, using the MSM tool to do a flash readback, which saves most of the firmware to the C: drive

If your phone is already on, you can also use the following command in command prompt to use ADB to reboot into EDL.
adb reboot edl

Still waiting for an answer from OP or anyone else: After we have made a flash read-back via MSM, how are these firmware files restored????

Flashed via Fastboot. For example if you extract boot.img from read-back and you want to restore the boot.img. Reboot your device into Fastboot and enter the following command in command prompt on your computer:
fastboot flash boot boot.img.
Depending on what you are flashing, you need to change the command accordingly. e.g vendor_boot.img
fastboot flash vendor_boot vendor_boot.img
