[Xiaomi Mi A2 / 6X Questions & Answers] rrdio:
Hi, Im new here. Just Bought my Xiaomi A2, which is weird cause i first order a Mi6X and the box is Mi6X. But the phone model says A2 (same phone at least as i search) and running on Android One 8.1.0 w/ security patch from september 2018.

The problem is it won't update via OTA (which is weird, cause it's a brand new android one). So im deciding i should do an image flash of newest MiA2 Android One (from xiaomi web ofc).

After installing all the drivers and adb.

First i try

C:\Users\user\ADB>fastboot oem unlock
FAILED (remote: 'Token Verify Failed, Reboot the device')
fastboot: error: Command failed

then

C:\Users\user\ADB>fastboot flashing unlock
FAILED (remote: 'Token Verify Failed, Reboot the device')
fastboot: error: Command failed

and also

C:\Users\user\ADB>fastboot flashing unlock_critical
FAILED (remote: 'Command not support: the display is not enabled')
fastboot: error: Command failed

none of them works. I already makesure to "enable usb debugging" and "OEM Device Unlock" in Devs Opt.

Did i wrong or skip something ?

PS : FYI, im doing it w/ the usb cable from the box to my ASUS TUF running on windows 10 via USB hub on USB2.0 ports (as i read and try the adb and fastboot having some trouble with windows 10 and USB3.0 ports).

also incase needed here the getvar all

Thanks Before. :):)

UPDATE :

I Tried to install twrp and just flash from recovery mode. It won't

C:\Users\user\Fastboot_edl-v2>fastboot flash recovery twrp-3.3.1-0-wayne.img
target reported max download size of 536870912 bytes
sending 'recovery' (37620 KB)...
OKAY [ 1.163s]
writing 'recovery'...
FAILED (remote: Anti-rollback check failed)
finished. total time: 1.167s

Booting TWRP image from fastboot also can't do a thing

C:\Users\user\Fastboot_edl-v2>fastboot boot twrp.img
downloading 'boot.img'...
OKAY [ 1.170s]
booting...
FAILED (status read failed (Too many links))
finished. total time: 11.247s

Also tried using MiUnlocker. It says my phone aren't bound to my account (i guess you can't link non MIUI phone to Mi account)

Also tried flashing in edl mode. It won't even enter edl mode

C:\Users\user\ADB>fastboot oem edl
FAILED (remote: 'Device is already locked!')
fastboot: error: Command failed

C:\Users\user\Fastboot_edl-v2>fastboot reboot-edl
