XIAOMI MIUI Unlock Re-locked bootloader ? - General Questions and Answers

Hello everyone,
I have a Mi 8 with a global rom unlocked. With fastboot, I re-locked the bootloader and now fastboot says :
"(bootloader) Verity mode: true
(bootloader) Device unlocked: false
(bootloader) Device critical unlocked: false
(bootloader) Charger screen enabled: false"
So it's done. But now the phone can't restart and in the Mi-Recovery I have a red message saying "This MIUI version can't be installed on this device".
I specify that I can only boot on Mi-Recovery or FASTBOOT mode.
So I tried to re-unlock the bootloader but fastboot says : "FAILED (remote: Token Verify Failed, Reboot the device)".
I tried with the Mi Unlock tool but I get an error : "Please add your account in MIUI's Settings > Developer options > Mi Unlock status."
Now you understand my problem, I can't go to these developer options because my phone doesn't want to start.
Can someone help me ?
Thank you

Update
I need to flash my Mi 8 via EDL mode but I also need an authorized account for that.
Can someone help me?

Need help to unlock bootloader SHARP Aquos S2

Hello!
Device: smartphone Sharp Aquos S2 (FS8010), Snapdragon 630, 4/64 Gb.
Problem: can`t unlock bootloader.
All necessary files and drivers are installed.
When I try run command "fastboot oem unlock", received this messages:
(bootloader) Verity mode: true
(bootloader) Device unlocked: false
(bootloader) Device critical unlocked: false
(bootloader) Charger screen enabled: true
FAILED (remote: Flashing Unlock is not allowed)
Can anybody help make unlock for this smartphone?
hold PWR-ON and VOL+ = Flash mode
hold PWR-ON and VOL- = Android logo with nothing
Fastboot devices command result no device ID. Thus I think that there is no bootloader of FS8010

FRP LOCK in Bootloop there is a solution?

brick my Huawei p20 now with frp locked already tried the command "C: \ Users \ ANDRE> fastboot oem frp-unlock Q9QG9UMJ6P1WR5JL"
...
(bootloader) The device will reboot and do factory reset ...
OKAY [4.446s]
finished. total time: 4.452s "
Ps* Q9QG9UMJ6P1WR5JL is code for unlock my frp
The cell phone restarts, it resets the error and when I enter fastboot again the FRP appears again, is there any solution to this?
Hope I can help you. Please try the following steps and let us know if it works for you:
1. In fastboot, use command "fastboot oem relock Q9QG9UMJ6P1WR5JL". It should do a factory reset and bring you back to stock ROM
2. After booting into stock ROM, activate developer options
3. In developer options, activate OEM unlocking option (i.e. enable OEM unlock)
4. Reboot the phone into fastboot mode and use the command "fastboot oem unlock Q9QG9UMJ6P1WR5JL". to unlock the bootloader. The lock statuses should be changed to:
Phone: unlocked
FRP: unlocked
6. Factory reset and reboot and you should be good.

Thank you very much for your attention.
Come on: Code Q9QG9UMJ6P1WR5JL is FRP unlocking. To unlock Bootloader the code is T1JR94CJQLNOWMIA
"C:\Users\ANDRE>fastboot oem relock T1JR94CJQLNOWMIA
...
FAILED (remote: stat not match)
finished. total time: 0.007s"
"C:\Users\ANDRE>fastboot oem unlock T1JR94CJQLNOWMIA
...
(bootloader) Necessary to unlock FRP!
(bootloader) Navigate to Developer options, and enable "OEM unlock"!
FAILED (remote: Command not allowed)
finished. total time: 0.022s"
Unfortunately the phone this brick, does not start the system only in fastboot and erecovery (which does not work) so I understood I need to unblock the frp to be able to perform the other task to revive my phone but when I run the "fastboot oem frp-unlock Q9QG9UMJ6P1WR5JL" everything that I have already reported in the first topic

-1,you need have dc-phoenix account ,

-4,power off you phone,connect your phone to pc and hold vol +and vol - the phone will appear installing update 5% ,

P20 Pro is bricked as well... (Need help)
I was driving in the car using google maps when all of a sudden my phone started to reboot, and got stuck in a boot loop... I haven't rooted or installed any ROMs on this device at all so I have no idea what triggered it to reboot or even get stuck in boot loop. I have it connected to my computer and have the "FASTBOOT&RESCUE MODE" screen pulled up and I can talk to it through ADB, but I have no idea where to go from here, I've been trying to follow many different threads but I cant seem to find a solution that works for me... Anyone please help!
On the "FASTBOOT&RESCUE MODE" screen it's displaying "Phone Locked" and "FRP Lock" I haven't found any tutorials on how to bypass the FRP lock for this device (While being stuck in a bootloop).
So far I've used fastboot commands

Black Screen Seconds After Power On, Official Bootloader Unlock Not Possible

Hi,
I'm having a problem with my HTC U11 Life (US Sense version). After powering on the phone, the screen turns black after a few seconds. I have time to enter my code but accessing settings or other apps is impossible. The issue persists when I boot into safe mode, meaning it's an issue with a system app. Strangely, some system dialogue options stay on, such as the Safe Mode text and the power/restart/airplane mode display. I tried to unlock my bootloader using HTC's official method, but I don't have the setting enabled to do so, and I can't access the settings mode. At this point, I'm fine with losing all my current data if I can fix things.
For reference, this is what "fastboot oem get_identifier_token" returns:
Code:
...
(bootloader) [KillSwitch] : /dev/block/bootdevice/by-name/frp
(bootloader) [KillSwitch] Last Byte is 0X00, disable unlock
(bootloader) [KillSwitch] oem unlock Turn Off!
OKAY [ 0.043s]
finished. total time: 0.046s
TLDR: Does anyone know a non-official method to unlock the bootloader and flash the stock firmware?

I dont know if there is an up-to date system.img for the us sense version or if you are able to flash it with a locked bootloader but if you could get one, flash it and reset the device using the stock recovery it should work again. I dont think there are official full firmware/software files for the US Sense Version to flash with the stock recovery or a RUU but this would be the best way.
To unlock the bootloader you could also use sunshine s-off, if i remember correct it supports the us sense version of the u11 life but its about 25$ for each device you want to unlock.

Redmi 6 Pro Locked Bootloader - No Device Access

Can anyone help me what to do. I recently flashed my Redmi 6 Pro to global version (IN) and got the message, MIUI cannot installed on this device, and unluckily... my bootloader was locked. I was trying to unlock it via adb fastboot and driver, but is says "Token verfication failed". Moreover, I tried MiUnlock Tool (latest version) but unfortunately, it is instructing me to go to Developer Options, where in I am stuck in Fastboot receovery 3.0 wherein the only options I have are : Reboot, Wipe Data, Connect to MiAssistant.
I tried connecting to MiAssistant but no luck. My phone cannot be detected.
Anyone with good insights on this will be much appreciated. Thanks
Also, anyone who can unlock my bootloader my MI ACCT : 6438898607
When Fastboot triggers error "Token verification failed" then it means that you haven't passed the unlock-token/key - what you would request from OEM/Carrier - by means of Fastboot to phone's bootloader before.

Please could you tell me if your device is able to boot to system ?
If so
Please open settings and go to about phone option. Tap build number few times until you get a message you are now a developer.
Once done, navigate back to system settings and enable oem unlock and usb debugging option. if not you need to manually flash OOS from boot loader.

Please try flashing recovery using the below command.
fastboot boot xxxxx.img
xxxxx.img is the recovery file name you download .
Please download the recovery img and zip files from the forum . If that doesn't work please let me know.
