Failed to install global rom via mi flashing tool, now phone stuck on fast boot.

Solved !!!
I was able to flash global miui 9.5.
Hi ,
So after finally the bootloader is unlocked I tried to flash the global rom via mi flash tool.
Update failed and an error message is update crc list failed !
I tried flashing back the chinse rom and I get the same error.
I can boot the device to recovery mode, but its mi recovery 3.0, I have 3 options:
1.wipe data
2. boot to system
3. connect via pc suite
tried with pc suite but it says my device isn't supported.
The computer recognizes the device via MiFlash tool but in adb via cmd when I type adb devices I get blank row and its unable to find the device.
how can I make my phone usable again please?
I have tried many things I found on google but nothing worked.
Thank you all

yes the phone is in fastboot mode, and I cant back to normal mode for regular use.
I tried to unlock again like you said it the program said the device is already unlocked.

Have you tried the first option, wipe data?

Don't panick, since you have fastboot mode it's not bricked. Let's start by booting into TWRP.
Download TWRP and put it in the same directory with your FASTBOOT.exe file.
Open a windows dos prompt and get to the same directory as your FASTBOOT file.
Reboot your phone into FASTBOOT mode.
in your DOS prompt type "Fastboot boot yourrecoveryfilename.img" (change the yourrecoveryfilename.img to the TWRP recovery image file you downloaded)
your phone should reboot into TWRP if there wasn't an error. TWRP won't be permanent (if you reboot out of TWRP it won't retain it), but will allow you to flash ROM.
I've only ever flashed all my ROMs through TWRP, never used anything else since i unlocked the phone.
Let me know how this goes.

Hello all.
Big screw up, I think. So I've had my MI 8 for a while now, no issues, until today I decided to install official lineage on it. The bootloader was unlocked. I flashed TWRP, but every time I rebooted the phone, it would go back to stock recovery, not TWRP. So here the issue started:
- Via Mi flash tool, I reflashed global MIUI 10 back to stock. I didn't realize I had relocked the bootloader...
- I tried reflashing TWRP without realizing I had relocked the bootloader.
- Thinking that the TWRP flash was done incorrectly again, I simply wanted to go back to stock, and attempted to use the mi flash tool to reflash, once again, the global stock MIUI 10. the flash tool said it was a success. (I still didn't realize I was on a locked bootloader)
- I am now on a bootloop. I can't get past the stock recovery screen, but I can go into fastboot. The recovery screen has a warning that the ROM cannot be used on the phone.
- I tried re unlocking the bootloader with the unlock tool, but because my Mi account credentials are not input on the phone (the phone was wiped clean), I cannot re unlock it.
What can I do? How can I get out of the bootloop, and hopefully re unlock and flash global rom clean again?

I finally got around fixing this. It turns out my phone was China, with Global ROM. So I did an EDL test point method and paid someone with an authorized account to access my laptop remotely to Flash the latest China ROM. I waited the required period for bootloader unlocking, and it's back alive!
I'm running official lineage 16, and I'm pretty happy with the results. I'm Using it as a daily driver instead of my all stock pixel 2 XL. No issues.

That's great news! It sucks that you were tricked into thinking your that phone is a global version. But at least you able to get things permanently sorted.

How to safely back to stock (factory state - get warranty)?

I want to back to stock on my Xiaomi A2 (full factory state - bootloader locked, no TWRP etc.) to get ma warranty back.
My current status:
- bootloader and critical unlocked
- loaded V10.0.8.0.PDIMIXM ROM (Fastboot official) from https://forum.xda-developers.com/mi-a2/how-to/ota-v9-6-5-0-odimife-t3823445 (used edl mode)
- previously I installed TWRP, decryption disabler and magiks
My last way to install ROM was by edl mode - downloaded fastboot version and used MiFlash tool (clean all). Previously I tried to run flash_all.bat from fastboot ROM, but it stopped on lashing devcfg_a (FAILED (remote: Flashing is not allowed for Critical Partitions), but I have critical unlocked.
My question is: Should I use MiFlash with edl mode to back to full stock with "clean all and lock" mode? Is it safe? I am afraid of locking bootloader and missing something what should be done before (I read it can brick the phone).
Should I install recovery first (missing in fastboot package), enable encryption or do something more?

Just flash fastboot image and relock and it'll be fine

I've reinstalled stock rom just yesterday, i had the same error with Mi Flash, i've flashed all manually from ADB, if you're coming from an Android Q ROM flash back the persist partition (i've a full Pie Backup) first or your WiFi MAC will disappear, when you've installed all (if the phone boot with Android One and everything Is working) just lock the bootloader (i've just used Oem Lock, idk about critical partitions) and you're good to go

When I used Mi A2 Toolkit, there were 3 options when I was unlocking bootloader: "Unlock OEM", "Unlock Flashing" and "Unlock flashing critical". I am not sure if executed all of them, but I am sure they were at least 2 of them.
So do I have to lock in the opposite way "Lock flashing critical", "Lock flashing" and "Lock OEM" or just "Lock OEM"? I need to be sure.
Can something happen if I will try to lock in that way, but I didn't unlock if before?

There is a toggle in developer options, "OEM Unlocking," which needs to be toggled on to lock or unlock the bootloader with fastboot. I would leave the bootloader and critical both unlocked until you are ready to use the warranty. If you have a bad flash and then lock the bootloader or critical then you might have a hard time getting everything working again.

Stuck in fastboot :(

Hello everyone!
As the title states, my Xiaomi mi 9 is stuck in fastboot mode, after i tried installing the latest unofficial port of Lineageos 17.1 for the Mi 9.
I can not exactly remember how it happened but i guess i must have wiped the phone after installing the custom rom. Silly me...
I tried the following things to try to unbrick my phone:
1. Using the Mi Flash Tool in order to flash the official Xiaomi firmware onto my device. I flashed these versions: 11.05 global fastboot, 11.08 EEA fastboot, 11.06 global fastboot. None of them worked. My phone would show up on the flash tool and the flashing itself was always marked as successfull but sadly my phone would not boot into MIUI and just stay frozen in fastboot mode. Restarting the device did not help.
2. Flashing twrp and trying to boot into it. Sadly, this also did not work out for me. Every time after i would successfully flash the .img file and reboot my device, the damn fastboot screen appeared.
So is there anything i can do? No matter what i try, my device goes into fastboot mode. I tried searching for the answer myself but those who had the similar issue did either not receive any useful answers or the Mi Flash Tool magically worked for them after a few attempts.
Thank you in advance!

Hello,
As long as you have access to fastboot mode, am sure you can recover your device.
You need to download the official ROM that corresponds to your specific devices. If it is global version, download the global version.
Also, before flashing, make sure you unlock the bootloader.

fastboot --cmdline "lge.kcal=0|0|0|x" boot twrp.img
this temporarily boots you into TWRP so you can reflash TWRP again. with this method the TWRP will be deleted once you reboot si you need to reflash TWRP in TWRP. then dont reboot, flash a Good working rom.

Similar problem here.
The line fastboot --cmdline "lge.kcal=0|0|0|x" boot twrp.img
brings up
FAILED (remote: 'Failed to load/authenticate boot image: Load Error')

How To Guide How to flash custom rom AND revert Miui

Hey there, first post here,
Got several higs with my RN10S playing a bit.
How to flash a custom rom in Xiaomi phones?
-First unlock your BL with MiFlashUnlocker.
MiFlashUnlocker
-assuming you're on 12.5.16.eu and wants to go to custom rom;
-first of all you need to be on 12.5.16global, only global version works atm.
So MiFU was useless atm. Or No:
Open MiFlashTool 2018.5.28.0 and Select the folder where you previously extracted 12.5.16global tzg .
Connect your phone in fastboot mode, rescan beward to the corner right.
You could clean all and flash 12.5.16 and MiFU would have been usefull
You could save your "user data"
Or you could clean all and lock flash and lock- BL, for just security purpose telling yourself you would Re-unlock in the future and thus you would need to Unlock it again, so MiFU again..
For tho who still follow, you just fastboot flashed 12.5.16global,
Boot it, i assume that this part is important, cause flashing TWRP just after a fastboot rom flash could end up in unmounted partitions,
Flash TWRP with phone in fastboot mode:
fastboot flash boot recovery.img
To temporarely replace the boot by recovery,
fastboot reboot recovery to boot onto it
Once in there, Switch to slot B;
(Reboot button- there you have option to use either slots)
Flash your rom and reflash TWRP by using the tick next to the digest, while flashing the rom.
Reboot Recovery to get things settled,
Format data to just keep the freshly installed rom, (Wipe, Data, yes) and get it working and running
Reboot and enjoy!
To revert simply fire up MiFlashTool and an original 12.5.16 tgz file, for security purpose,
You may wants to format, flash, lock.
The same technique could be applyied if running Miui 13 and wants to revert to 12.5
There is ARB but doesn't seem to be taken onto consideration bout the program
I got a red !Phone is destroyed, press power to power off! And my phone is still working actually.
I take absolutely no credits for that,
Just figured out the messy workaround and gathered informations,
These roms are not from me, and i Can confirm their bootability,
Beside that, lightweight, but no fast charge.
Got back to stock, cause of banking app, fast charge
Go feel free to post your techniques to get yourself out if situation

twrp is not on redmi note 10 s yet is it ?

Question Unstoppable bootloop after flashing bad boot img

Hi everyone, I wanted to root my phone because my google pay way not working after I unlocked the bootloader of my phone.
I used magisk to flash a version for my redmi 2201117TY, but after using fastboot to flash my "patched" rom back to my phone, it is now booting over and over again.
I installed twrp to try to install another ROM, but I'm not sure it'll work.
I installed several redmi note 11 img to see if it would fix it but i did not (V13.0.6.0.SGKEUXM, V14.0.2.0.TGKMIXM and V13.0.3.0.SGKEUSF which was my original one i suppose)
I just want to have an usable phone even if it means cleaning everything. How can I format everything back to make it usable?
I have access to adb, fastboot, TWRP. (usb debugger on)
I am not sure I can find the exact rom as it was a really wierd version from my operator (SGKEUSF) and I can only find one on internet which happen to not work. How can I unbrick my phone now?
NOTE : the SGKEUSF is an overlayer of the SFR (Altis) network so i would rather not use it

Format (not wipe) data in twrp, flash a rom that fits your needs (on sdcard), reboot recovery (!), reboot system. If fastboot access is given it's fixable. Had the same thing many times with spesn. This is the way it always works for me.

When you say "flash a rom", you mean a recovery or a fastboot one? Does it have an influence?

Just download latest version of MiFlash, download RN11 fastboot ROM, flash the ROM via MiFlash. In MiFlash make sure to to check the box whether of not to lock the bootloader after flash. Just to be safe leave it unlocked until after the phone is safe.
