[Q] KATE Official BootLoader Unlock

Hello all... has anyone managed to unlock kate device with official method? i am trying and gets stuck at 50%....
if yes how?
Few days ago search something about 50% bug and it`s seems that till today nobody unlock Kate with official way. Yet here is probably only unofficial method http://en.miui.com/thread-345728-1-1.html Or you can wait till Xiaomi remove this bug.

Hello, I unlocked my kate version the official way. First I unlocked it using unofficial method, but I got the permission to unlock the bootloader. I flashed the "Global Developer" fastboot rom using MIFlash, which locked my bootloader. Then, I rebooted my device into fastboot mode and unlocked it using the MiFlash Unlock tool.

Did you setup Mi account on the device after ROM flashed or just restarted to Fastboot after cleanboot?

Yes, I did setup MI account(the one on which I requested the permission) and synced it once before booting the device into the fastboot mode. Make sure to enable OEM unlock and USB debugging before fastboot.

did u also associate the xiaomi id with the phone under Mi unlock status in dev options?
It is another step which is failing on my device. It says it can't verify the device and ask me to retry after 1 or 2 minutes, forever.

I did not. Just logged in the MI account while setting up the rom on first boot.
I just tried official way to unlock my kate with global developer rom last night and I was very happy that it worked on first attempt.

How to return to MIUI from Custom ROM with locked bootloader?

Pretty much what the title says. I'm on Android 7.1 (crDroid) with TWRP Alka installed and bootloader initially officially unlocked but now it shows that it's locked. Also, I tried unlocking with MiUnlock and it doesn't work. What do I do?
Just use MiFlash in Fastboot with Fastboot MIUI ROM. If you scared of EDL mode and/or it said your bootloader is locked then read below:
You can re-unlock it by using fastboot. You need adb, fastboot, xiaomi driver to do this. I recommend to use universal ADB & Fastboot.
Boot your phone to fastboot screen (aka bootloader mode) by using advanced reboot or adb terminal "reboot bootloader" or hardware key: Volume Down + Power
Code:
fastboot devices
fastboot oem device-info
If it show up with "Device unlocked: false" then unlock it by using:
Code:
fastboot oem unlock-go
Click to expand...
Click to collapse
If you setup MiCloud before going custom ROM, you will need to enter your MiAccount ID/E-mail and password.
Your phone will be locked again after using MiFlash, but you are at MIUI and you can use MiUnlock to unlock it anytime.

The frp can be blocked again from the developer's settings, settings> developer options> Enable OEM unlock.
For the boot manager, you must go to the adb command window and, with the device in fastboot mode, you must enter one of these two commands (if one does not work, try the other):
fastboot oem lock
or
fastboot oem relock
That should block the FRP and the boot loader again

Mi Mix 3 5G wont boot to android

Hello I have a xiaomi mi mix 3 5g that I never removed the bootloader on, as it had the stock EU firmware on. It has recently been updated to to MIUI12. however the battery went low and went all weird and now constantly reboots.
I can get to fastboot by holding down the power and volume down, I have also tried a wipe device by holding down the power and up. From what I have read I i cant re-install fastboot firmware without and unlocked bootloader. (can someone confirm that this is correct) as its not clear.
***I have now confirmed this I have tried to install firmware using xiaomi flash tool and fails with the following
"Error: erasing boot Failed remote erase is not allowed in locked state. so this confirms it.
Also I cant unlock the bootloader as it wont boot. Does any body have any idea of what I can do with this phone? any help would be apprciated
thanks
The error I get when trying the mi unlock tool
Couldn't Unlock
Please add your account in MIUI;s Settings > Developer options > Mi Unlock Status
Seems the update miserably failed, Android OS got corrupted. My suggestion: Re-flash phone's Stock ROM ( phone's battery should be fully charged ! ).
To keep you updated:
FASTBOOT is a program used to manipulate ( list, install, erase ) the non-volatile memory such as flash filesystem partitions on devices that adhere to the fastboot protocol, via a USB connection from a host computer. It requires that the device be started in a boot loader mode ( AKA fastboot mode ) with the fastboot protocol enabled.
Take note that fastboot ( the fastboot daemon ) is integral part of phone's bootloader.

How do I re-flash stock rom when the bootlloader is not unlocked.
I have already tried Xiaomi's flash tool and it when flashing the stock ROM and get the following error
"Error: erasing boot Failed remote erase is not allowed in locked state"
Are there any methods of flashing a stock rom with a locked bootloader ?

I have already tried that method When I flash using the flash tool I get the error "Error: erasing boot Failed remote erase is not allowed in locked state" My bootloader is not unlocked is this method supposed to be work with a locked bootloader. Bit of chicken and egg situation. I cant unlock the bootloader as I cant boot the device and I cant reflash software as I don't have an unlocked bootloader.
AFAIK you always are allowed to flash an original firmware image without unlocking the phone's bootloader.
If you can access the device by means of ADB try to flash the Stock ROM via ADB:
Code:
adb devices
adb reboot sideload
adb sideload <LOCATION_OF_STOCK_ROM_ZIP_FILE_HERE>
C:\adb>adb devices
List of devices attached
f625af1 sideload
C:\adb>adb sideload miui_ANDROMEDAEEAGlobal_V12.0.1.0.PEMEUXM_9e4961bf09_9.0.zip
loading: 'miui_ANDROMEDAEEAGlobal_V12.0.1.0.PEMEUXM_9e4961bf09_9.0.zip'
* cannot read 'miui_ANDROMEDAEEAGlobal_V12.0.1.0.PEMEUXM_9e4961bf09_9.0.zip' *
@sivhead
Try this:
Rename the file to rom.zip and then start "adb sideload rom.zip"

I also thought its worth mentioning that I have never registered the device with mi connect
Also enable usb debugging is not enabled.
aqnd THe bootloader is locked .
Man I wish I would have unlocked the bootloader when I got it and put a custom rom on. then I wouldnt be in this situation. how ironic that I wanted to keep it stock
so I am at a loose end
