Bricked After OTA update - Redmi 7A Questions & Answers

My Redmi 7A got "system has been destroyed" after OTA update and restart phone :crying:
-i haven't MI Account registered
-USB debugging is OFF
-Unlock by OEM is OFF
-Bootloader is LOCKED
Because these....i can't get an way to unlock bootloader and flash the ROM.
The "only way" is use "emmc firehose" mod to bypass authentication over EDL method.
So..anyone can help me? I'm brazilian and there's no Xiaomi Customer's here.

Try visiting an expert. They have that weird box thing I don't remember what is it called but it fixes things. Used to go there with my old infinix hot2 when it's bricked.

same here it is possible to flash system.img only?

weird problem xiaomi mi9T

Hi everybody
I redid an installation of my xiaomi mi9t under miui 11.0.3 to start again on good bases because I had done a lot of trying to try to succeed in rooting it
So I relocked the bootloader and I followed the tutorial from A to Z to root the tel.
So these are the manipulations I did:
Unlock the bootloader with the miui tool
Fastboot flash recovery twrp.img
Fastboot boot twrp.img
Installation of the magisk zip.
Restart.
And then I restore my data with micloud and when I go to developer option it says that my bootloader and locked and OEM unlocking is no longer grayed out I can deactivate it when before it was not possible.
I don't know if it's the fact that I restored via micloud or that I used the xiaomi native security and cleaner app.
However my phone is well rooted and unlock bootloader because it is marked unlocked at startup and for rooting all the apps that request root rights have it.
Thank you for your answers.

I would advise you to reload the stock ROM again using MiFlash and then try to unlock the bootloader again
Seems like the Mi unlock tool cannot get your device's info so yeah try to flash the stock MIUI again and then try to unlock the bootloader again mate.

I have a little problem... Mi9t locked bootloader, bricked

Good Morning
I wanted to flash a Global Rom to my Xiaomi Mi9t. I did this with MiFlash, but i forgot to click on "clean", so the default option "clean and lock" was enabled. It failed to install this version and now the device is locked and is also bricked, it only starts into recovery and fastboot.
I hope someone can help... =)
try flashing the the latest fastboot firmware via XiaomiFlash.

PLEASE HELP! Redmi 3s bootloader cant be unlocked at all!

Ill try explaining it clearly
Yesterday I decided to go back to the stock firmware by flashing it and choosing the option to "clean and lock the bootloader" for the Redmi 3s MIUI 10.2. However I got many problems when going through my phone. First, Wifi and hotspot wont work, the message "device storage is corrupted, your device is unsafe" keeps showing up and lastly, i cannot connect to the MI account as it'll show the message "Couldn't check device security info".
This makes my phone unusable, so my choice is to flash a new firmware, if i don't unlock the bootloader the message "critical partition flashing is not allowed" will show up when flashing the firmware. So I need to unlock the bootloader.
The first one is the Mi unlock tool. This unlocks the device by signing into the MI account, which i can't because it'll show the message "Couldn't check device security info" again. This means that I can't use the Mi unlock tool.
The second one is the ADB and fastboot method. When booted to fastboot, i typed in "fastboot oem unlock" but the error shows and says "token verification failed" error and just reboots into fastboot again.
This then leaves me into nowhere to how to unlock my bootloader. Please help and thank you so much!
