yes it can. i manage to flash official twrp with official and unofficial bl unlock.

Some user tell on whatss app group , they cant enter on twrp with official bootloader unlock

For downgrading you must to unlock "critical" area with the same unlock key you used for unlocking bootloader. Just do fastboot flash unlock_critical <key file> and fastboot oem unlock_critical and confirm the operation on your phone. Then you can flash .nb0 firmware .309A version with OST 6.0.4. All data will be lost! If you have no experience and not sure that you doing right just give it to someone who aknowleged what to do!

FRP Locked

I think I messed up quiet a bit. I wanted to roll back from Lineage OS 14.1 to Emui 5.0 (I obviously didn´t make a backup ). So the first thing I did is flash Moonlight v3.5 but when I finished the setup I noticed that the camera app was missing. So I got the idea to flash the stock rom per dload, but It gave me the error Firmware Missmatching and now, when I boot into fastboot mode it says FRP Lock in green Text and i couldn´t do anything with fastboot commands or TWRP(Bootloader still unlocked). Then I got the brilliant idea to flash the stock recovery. And then nothing worked anymore (No dload, no recovery, erecvery says getting package info failed). Is there a way to unlock that FRP Lock without using DC Unlocker/DC Phoenix? Because when i manage to unlock FRP Lock i can flash TWRP again and install stock Rom properly.
Model: EVAL-AL10
Bootloader: unlocked
FRP: locked
Firmware: none (I think)
TWRP installED or not?

Dload doesnt work.How can dc phoenex be used? Can you provide any links to a good guide?
https://www.dc-unlocker.com/DC-Phoenix-flash-repair-tutorial
you must boot into bootloader then flash the stock rom (UPDATE.APP) with the phoenix software (paid service ~15€) then you must re-install the stock rom again with dload methode to get a clean system on your phone

Try booting into eRecovery (Power+Volume Up+USB plugged in) to restore the system which [will] wipe all data (excluding /sdcard)

Try to unlock the bootloader even if it says that it's unlocked
Type this command in adb
fastboot flash recovery_ramdisk [name of twrp]
Make sure you're using the right version of TWRP that works with Oreo

MI A2 not receiving OTA

Just bought MI A2 from official dealer and the phone is stuck on Android one version 8.1.0 and not getting PIE via OTA.
Is there a safe method to manually install the latest stock PIE version of android one ?
Is it possible the update was removed from the servers ?

I have the MI FLASH TOOL installed but it would not succeed to install the drivers.
I assume nothing will work if windows does not have correct drivers installed.
Can I install the fastboot driver manually ? which driver ?
Btw, the phone is detected in fastboot mode by the FASTBOOT/ADB command line interface. Is that helpfull to me ?

Afaik...to flash latest pie base firmware, first you need to unlock your phone's bootloader and then only you can flash available fastboot firmware (pie based) using MiFlash tool.
Try to OTA update using WiFi(Keep the phone to airplane mode and just turn on the WiFi and then try to update). Also before updating the phone just turn on the oem unlock switch under developer option on safer side so you can unlock your bootloader later if anything goes wrong while updating your device since many people have reported that they've bricked their device during updating their device..
Updaing to PIE was successfull.
Used this guide to unlock bootloader: https://www.androidexplained.com/mi-a2-unlock-bootloader/
Then used the MI FLASH tool to apply the stock rom. First atemp failed with "write error" after 55 seconds, but I tried a second time and this time the process completed.

I hope you flash both this fastboot codes when unlocked your bootloader.
Code:
fastboot flashing unlock
fastboot flashing unlock_critical
Unlock_Critical is require to flash custom roms and if you would want to revert back to stock from custom rom.

Yes, did both commands. However, after flashing PIE via the flash tool, the bootloader became locked again.

You must have selected "flash all and lock" under MiFlash tool so it lock the bootloader as well but now you know how to unlock it so do it whenever you feel like unlocking your bootloader..

Thank you very much now It works, but I want to ask you: Why can not i enter in recovery Mode? I tried the power on and volume down combination, but the phone enter only fastboot mode with "oplus verification failed" message. If I do a factory reset under the Android, the phone load the recovery, until resetting.
