Good night, I have been bricked my device for over 5 days, I was trying to install the Custom ROM pixel experience, but when I installed the TWRP the wifi would stop working and I had the brilliant idea of ​​installing another recovery inside. from TWRP itself and to go further wrong I still unintentionally blocked the bootloader, now I've tried to flash several MiFlash and none successfully, I took it to a technician and he tried a test point and also couldn't make it work, can anyone give a light that I'm already desperate without knowing what else to do

Does it boot? Fastboot modd working? What about recovery mode (i think itsnot working too)?

Bro, You can unbrick your device by flashing. First you need to remove back shell of your device then you need to flash your device in EDL MODE (EDL = Emergency Download ) . If you want help you can meassage me . i will provice you with Flash file & Instructions :D

I have bricked my phone 2 months ago, and even xiaomi repair center said there's nothing they can do. I have the same situation with OP, it keeps rebooting to fastboot mode, and EDL flashing does NOT work for me. The repair center said that the only hope of the phone is getting the full motherboard assembly replaced.

Did you try erase and flash via qfil + edl. The IMEI/Mac addresses and efs data needs to be re written but I think it will fix ur brick atleast. From wat I understood u have locked the bootloader back after flashing a custom rom. Secure boot will not allow the custom rom's to boot with bootloader locked coz the signatures do not match the phone's factory signature burned into the phone's bootloader.


This could help u understand:
https://source.android.com/security/verifiedboot/boot-flow

Note: each time u flash the phone via qfil or edl in general restart the phone in edl mode, qcom phones are allowed to be flashed via edl mode only for the first try after putting the phone in edl mode, the second and the following times u try u will get a Sahara fail error.

    Does the flashing procedure success? What does the MiFlash says when finished flashing?

    Try switching to active slot to a before flashing.

    Miflash gave me a success message. Finally got stock booted changing active slot to a and flashing again.
    Thank you very much for your reply!

    My mobile also bricked when im try to install custome rom and tried to flash latest stock rom 10.3.16.... But no use when installing finished it reboot to a warning 'system has been destroyed' for 3 sec and rebbot to fastboot mode... Then i tried...
    1) slot set to 'a' (fastboot set_active a)
    2) downloaded old firmware (10.3.4.0)
    3) mobile connected to system and open the bat file in rom folder 'flash_all_lock'
    4)it installs rom directly with cmd and without miflash tool
    5) bhoom.... Its rebooted to erase screen and mobile was unbricked

    *If it was not switched on and mobile go to fastboot mode than open cmd promt and set slot to b and swith it on by pressing power button for 10sec
    Locking your bootloader (flash_all_lock) without testing the device first is extremely "brave" idea. Never lock it unless you're 100% sure that phone can fully boot and everything works.
