If you install the stock ROM than which version did you install?
OR
If you have restored than did you restore the stock recovery?

Did you use
Code:
fastboot flashing unlock_critical
or just
Code:
fastboot oem unlock-go
You have to do
Code:
fastboot flashing unlock_critical
to be able to reflash bootloader
Thank q sir.

I am in same position! Bricked maybe ...
I previously got an unlock bootloader key and all was great.
I then went to relock my bootloader and now I can only get into download mode.
I tried loading up into OST but it freezes on ‘reflash service bootloader’.
I was on the latest Android P Beta.
I even tried unlocking the bootloader using the original .bin file but that didn’t work.
Is there anything I can do?
Deleted....
I had the same problem yesterday evening.... I download the rollback zip to Oreo on Nokia developper website, i copy it on my external sd card, i boot in recovery mode, wipe all data, and i choose apply an update from sd card, and i zelect the zip, and it works well!
The only problem is the loss of all your data if it was not saved...

If u are on locked bootloader then OST won't work. OST will work only in Unlocked bootloader.
And u can't enter in recovery mod. Only download mod. Correct? Same happened with me also. Now my phone is in service centre for tha past 11 days. They told Motherboard issue and can claim warranty. So i am waiting for new motherboard and my 7+.

Tool has a revert to stock option. You can also download the latest fastboot image and flash via MIFlash.

will that lock bootloader again?
To lock the bootloader you can either use the tool (which has the option to lock) or do it manually with the commands
Fastboot oem lock
Fastboot flashing lock
And finally
Fastboot flashing lock_critical
Be sure to flash stock before locking the bootloader, otherwise you may end in a bootloop.

You only need to lock the last two if you unlocked them.
Hello,
Im trying to relock my bootloader again, did i just have to use the "fastboot oem lock" command? Because i read it somewhere that i have to flash stock rom before locking the bootloader, if yes can someone give me the link for stock rom and how to flash it, FYI when unlocking im only using "fastboot oem unlock' command, not doing "fastboot unlock critical blablabla".
Any help would be appreciated, thank you
as far as i know, you need to flash stock bootloader of your current android build then uninstall magisk (if you have it) and just use fastboot oem unlock and you're done (note! backup all your data cause it will make a full wipe)

I stopped after unlock bootloader only, i didnt root it at all, so you mean after flash just run fastboot oem lock command?

Then you don't need to flash anything at all. Just run fastboot oem lock command.

Oh. Please sure that you have back to original boot image before relock or your device will brick.

I never relock bootloader .. what I know is you must have fully stock ROM installed then only advisable to lock bootloader. Never do on rooted stock & custom ROM.
Maybe someone else can advise you better.

"Fastboot oem lock" seems to be depreciated for Mi A2, better use "fastboot flashing lock" instead of "OEM unlock" (though probably these are still equivalent).
And yes, full unlock is achieved when after general unlock you are unlocking critical (once more approve on phone, once more user data erased).
For your information. I've just bricked my Redmi 10S with stock ROM with the command ""Fastboot oem lock" :-(
I was trying to install stock rom after installing RR rom. MiFlash said "flashing is not allowed for critical partitions" and when i did "fastboot flashing unlock_critical" from cmd i got "remote: Flashing Unlock is not allowed". I then used the allinone tool from xda and pressed "lock loader" to unlock it again and ended up bricking the device as it now shows "your device is corrupt. it can't e trusted and will not boot" I can't enter recovery either only fastoot and nothing works.

Dude, how many threads do you need to create, it won't make it any more likely that anyone will help you
Your problem is caused by that you only unlocked the bootloader and not critical partitions
Which stock rom were you on before flashing a custom one?

Are you sure?, if so, manually flash boot, system and vendor using fastboot to your current slot
Fastboot flash boot_a boot.img
Or boot_b if active slot is B etc...
Then go to developer options and enable oem unlocking, if you can't enable that option, lock the bootloader, enable the option then unlock bootloader and critical flashing

Hi , sorry for my bad English , if you can open you phone and enter to EDL MODE and flash the stock rom of your device may be solve your problem ,
(I get the same problem trying to install a custom rom)
If you can't acces to EDL via ABD i think that you only can enter to EDL disasembly your phone .. Suertee xd
Yo también me desesperé
same problem
i got the same problem, won't start normally, hangs in boot screen so can't enter the phone to put it in usb debugging, only responce is through fastboot mode. Every attempt is failing due to locked state and unlocking is not allowed.
