Hello. I want to downgrade back to android 11 and I know unlocking the bootloader is needed in order to flash stock ROM. I read that oppo doesn't give the possibility to unlock the bootloader, is it correct or did anybody find a way? Thanks!!

Hey guys, I was just wondering if someone could help me out in telling me the procedure to relock the bootloader of this device, I am currently using pixel3rom and want to revert back to stock miui firmware 10.1.2 and relock the bootloader. I have the global version of the mi 8 and I was told that it would be possible to relock the bootloader of this variant but I'm not sure how to do it
Any help will be greatly appreciated guys

i bought a mi 9 lite and it came with the russian rom.
I wanted to unlock the bootloader and install the official globlal ROM with mi flash. can i lock the bootloader again with me flash when i install an official global rom?
or
is there a guide to install a global rom without unlocking the bootloader? and without using tools?
You need to first unlock your bootloader in order to fastboot flash the global rom (using MiFlash). After that in the MiFlash tool there is an option to "Flash all and lock" which will lock your bootloader again. Unfortunately there is not a way of doing it to my knowledge without unlocking your bootloader.
Here's the official guide here: https://c.mi.com/oc/miuidownload/detail?guide=2
Never, ever re-lock your bootloader as this will result in a hard brick that can only be resolved with EDL/authorized account!

Not to my knowledge. I have done it before with my device. Sure if you want to use custom roms/recoveries you will need to unlock your bootloader again which you can do if you are using an authorised account. However, if you are really worried about this happening, you might as well just keep your bootloader unlocked.

Before i could unlock my device, i was able to flash a global rom with a non official tool which name i can't remember.
Global rom was the only one i was able to flash. So yes it's possible.
ok
On which ROM and Device you CAN and CAN'T Lock Bootloader!

I think you're right
Hi
I need to downgrade a note 9 from Android 10 to 8.1. When I was going to unlock bootloader, it gave me warning that some random things won't work if use custom os but I just want to downgrade. My question is that after I downgrade, can I lock the bootloader again.
Thank you so much
I have a Moto Edge S pro, and he came with the global ROM, and of course, with the BL unlocked. My question is: if I root my device, will I be able to install android 13??? Cause he still on Android 11 and it takes a lot of battery, and using root can I block the bootloader? Or just using the unlocked bootloader, can I update my phone by myself? If yes, how? I saw here a lot of manuals but I'm not confident to do by myself without help, can someone help me? Thank you everybody!!!
There is no problem
I have official ROM 13
After the update locked the bootloader
and no problem(moto edge s pro)

Ok, I downloaded the stock rom (using the RMSA) but how can I know that it's already the one with android 13? Because my BL still unlocked and I know I have to put the command to lock again. So, if I install again the stock ROM of android 11 and block the BL, when my phone turns on, will I be able to update using OTA?
My suggestion that once the bootloader unlocked on a motorola phone let it stay unlocked then flash whatever compatible rom you want but don't lock back. Sometimes under special circumstances locking back can brick a phone. If there is an anti-rollback protection in your phone then it can brick the phone with locked bootloader and previous Android version.
