Stock script flashes "empty" image to slot system_b (ask Xiaomi why), so if a phone is booting from slot_b, it won't succeed.

thanks man
according to what i read , the otp failure is because of twrp and system modification .
so if we patch boot.img with magisk and then flash it with pc and root device that problem wont happen ?

Correct. You will need to create manual backup of stock boot image for Magisk to restore, here's how - https://forum.xda-developers.com/mi-a3/how-to/guide-create-manual-backup-stock-boot-t3988345

You cannot go back to 6.0 because the bootloader is now for 7.* I would advise you to flash stock 7.0 again and follow the upgrade path to 7.1.1 found here:
https://forum.xda-developers.com/moto-z/how-to/how-to-update-to-official-7-1-1-moto-z-t3640298
Alternatively, you could flash a custom ROM. If you use Moto Mods then you can flash Resurrection Remix with Mods support.

It looks like you did an incomplete fastboot flash.
It is a long and tedious process but here is a windows batch file that automates it:

Another solution is to flash this https://forum.xda-developers.com/moto-z/development/rom-erfanrom-flashable-zip-t3646962 in TWRP DO FULL WIPE FIRST

I see that you are posting on the other thread. What is the truth?
You need to flash the modem file twice. For some reason it doesn't always flash properly the first time and you need to flash it again. I do recall somewhere somebody mentioning not to use batch scripts to flash as you can miss some flashing issues occasionally. As stated previously, once you are on the 7.x bootloader, there is no way to roll back unfortunately. Try reloading the full firmware through fastboot and make sure you flash the modem twice. I recently had a similar issue on a Moto X Style and I had to flash the modem twice to fix WiFi issues.
Hope this helps.

Try a different twrp that has helped me kingmezi is working for my but keep in mind you need to format data (and check the mount setting and swipe to modify at start)

Thanks for the answer, but it does not allow as the previous message says ... it does not allow to install any type of recovery either stock or custom ...
It does not allow to mount any partition, Boot, Recoery, etc ... from the TWRP Menu
Unlock bootloader install via command
thks
I do not think I'm spying.
1. The Bootlaoder even if it is released ... it sends you immediately to the TWRP ... once inside it says no OS installed, and it does not allow doing anything because it does not load any of the partitions.
2. Even if you release the Bootloader, it does not allow you to install another type of TWRP ... nor restore backup files ... it only allows you to flash the different OEMINFOs as if it were a rebrand.

Then you might try dc phoenix but its not free
That can install even if you have a locked bootloader firmware or even if you are bricked like your cellphone
you can download the latest firmware without problems googe it and try it (cost about 15dollar to unbrick)
If the twrp dont work cause the parameters are wrong what twrp are you using we have here 3 differents for the Huawei if im right try kingmezi twrp its working fro my l21-b432 i think it was

I managed to install another custon recovery, that allows to see the partitions, and that the team has a system ... but at the time of restart the bootloader error comes out ... and giving low CMD fastboot has the same unlocked ... perfect ... when I send the command fastboot flash (Boot, recovery, recovery2) it says Failed ... and I can not install the recovery stock.
P.S: Thanks for the advice of DC Phoenix ... I had seen it and I will try ...

If your bootloader is unlocked, try installing twrp recovery, and flash from there, it may work. If not, flash a custom 5x rom, and really enjoy your phone. The 5x is old now, no warranty now, and there are a lot of stable roms for it(I use arrows 9.0) . From lollipop, to pie now, it’s pretty indestructible.

I am so done....

I just want to finally try and install a custom rom into my Mi A3 which I rooted a while ago. I know I need this tool called TWRP, after encountering a myriad of errors trying to follow this guide step-by-step, I finally got to the point when I need to type "fastboot boot twrp.img" to boot into TWRP temporarily. But alas that couldn't be so easy now could it... Now I get this thing

is the bootloader unlocked ?
i think i got same message and it was because i forgot this.
I think there are better guides. Not sure what state your system is in. I would re-install the stock rom and start afresh. Unlock your bootloader, check which slot 'a' or 'b' is the current slot, and then follow the instruction of the Custom ROM you are trying to install. It might need TWRP but Lineage Recovery is equally as good.

I assume this means I can just go back to magisk and hit restore images, then return to fastboot and switch to slot b and install twrp there?

As I said, as I am not sure what state your system is in I would suggest 're-installing' the stock rom from your PC, rather than 'restoring' an image from your phone. If you have backed up your data etc (eg on Google Drive) you can restore it after you have re-installed the stock rom. You can then start again from scratch.
The latest stock rom fastboot images can be found here
https://xiaomifirmwareupdater.com/miui/laurel/
Tbh I haven't restored an image from magisk myself so I can't confirm what you are proposing, though yes I switched to slot b and installed TWRP.
You might also want to read this article on A/B partitions
https://www.xda-developers.com/how-...ess-updates-affect-custom-development-on-xda/
Try this
https://play.google.com/store/apps/details?id=com.smartpack.smartflasher
Flash TWRP installer through the app
Just a few tips when you do get to TWRP:
Disable dm-verity
Format data and wipe cache after you flash the new rom before first boot
Use a patched boot method instead of flashing magisk in TWRP on custom ROMs. High chance of soft brick.
DM me if you need help.

Guys, what do you mean when considering the first video as solution? he just downgrades from 12 to 11. This is not a solution. We need a solution for android 12 we don't want to downgrade to android 11.
Am I missing something?
Yeap , this need a really performant and interested developper to do it . But it seems there isn't ... Recently I updated stock C10 to C11 and all commands are there ... BROM mode , recovery , fastboot but apparently they are triggered by something . Personally I don't understand this way to hide those but for me isn't a impediment , I don't want to root or install TWRP . There are important astral signs that will be in a few months A13 for OnePlus Nord 2 , so for now I'm feeling good

ya you will have to follow the tutorial what is posted in the OP, there is a youtube link. I followed it but in the Customer made xubuntu flash drive the MTK tool was not working, so i created a Ubuntu bootable USB disk and then booted it installed all the necessary files for MTK tool from the Github page and i flashed the Android 11 to my phone then i was able to boot into Fastboot mode.
In realme 7 and android 12
I managed to get into fastboot mode using the following command:
adb shell reboot fastboot
