Locked bootloader on Global 8.0.3.0 & Global developer rom

A lot of users have locked bootloader on Global 8.0.3.0 rom, which can not be unlocked in regular way without deep flash cable (for installing china rom for example). In near future (if they do not delay again) we will have Global developer rom for Xiaomi mi 5s, so simple question is, can we install that rom with updater app even with locked bootloader?
Install Global 8.2.1.0 (en.miui.com/thread-567657-1-1.html). There you can enter the unlock informations in developer options.
I think that rom can not be verified when installing with updater app. With Mi flash I can not install because I have locked bootloader...
However, that was not my question... I asked can we install global dev with updater app if our bootloader is locked?

You can install the fastboot version (not recovery) of the rom through miflash. In fact, that is the only way to go from global stable to china developer with locked bootloader or at least the only way I know. The global developer has been delayed.

So, if I understand you, china developer & global developer can be flashed with Mi flash even my bootloader is locked?

I still think you need to deep flash in order to do this.

Nah, you really need deep flash for this or expect for OTA (which has been delayed so long).
I must wait for OTA only to bound account to device in developer option, to unlock bootloader...

That was the only way I managed to unlock the bootloader, by installing te developer ROM. The updater app didn't work, neither did MiFlash.
I will wait for OTA, because I do not have deep flashe cable and do not know how to flash with that cable....
Hey, developer global is available and you can install just download the file and use updater app
I can confirme that, did the update with de updater app and everything went fine
Thanks
Just installed global beta and gonna try to unlock bootloader...
EDIT:
Bootloader unlocked... If anyone got error "Binding time is too short...", just use older version of Mi flash unlock tool, or wait given time to unlock bootloader.
Which older version of Mi flash?
What is the ver number of it?

Just update to Global beta with updater app (before backup everything, because is gonna delete data), than you can unlock your bootloader...if you have permission from Xiaomi, of course...On Miui 8.0.3.0 you can not unlock bootloader.

Your phone got bricked or not? If not, try flashing/downgrade miui using stock recovery option..just make sure its the latest oreo one.

Downgrading MIUI 11 to MIUI 10

Have someone already tried this? Downgrading from Miui 11 to Miui 10? Or from some Miui 10 to another version of Miui 10? I've the Redmi 7 Global and my bootloader is locked. I tried downgrading using the built in update app and choosing a previous package but it doesn't let me to do that. I don't know if it's possible by flashing Miui 10 in fastboot, has anyone tried? Fastboot getvar anti gives me =1 and I read somewhere that =1 means there's no problem to downgrade but I'm not sure

You will need to unlock bootloader and download miui 10 fastboot rom and remember when flashing select clean all and lock if u want to lock bootloader.
if i want to download grade from 11.0.8 to 11.0.5 without unlocking bootloader (i mean by recovery zip)

RECOVERY - If you try to flash Recovery rom in Redmi 7(ONC_LITE) or Redmi Y3(ONC) then it will successfully flashed !! i personally tried and success.
FASTBOOT - If you try to flash any rom in Redmi 7(ONC_LITE) or Redmi Y3(ONC) then it says only nop and sig tag can be received before authentication
EDL - If you try to flash any rom in Redmi 7(ONC_LITE) or Redmi Y3(ONC) then it says only nop and sig tag can be received before authentication

Nope Xiaomi restricted downgrading Option via updater app the only option left is fastboot
To anyone,
I just want to know if it's possible to (& how to) downgrade (WITHOUT A PC! aka using just zip file) for my Redmi 7A using the update app\tool on MIUI devices, before I update it... I'll hate to upgrade only to find bugs etc... so it's always good to know how to downgrade jic as I'm very cautious & I've never tried these things. tnx.

Anti-rollback Help!

Hello everybody,
yesterday I installed the ROM V.11.0.7 but it doesn't make any changes. It seems official. It's terrible! Today I tried to put the V. 11.0.5 but it does not even let me install the TWPR 3.4.1B I probably made a mess.
It doesn't allow me to downgrade.
Can you help me please?
Thanks a lot!

To come back to miui from AOSP you must use miflash tool to flash an official fastboot version of miui. It's necessary because miflash restores some partitions that are altered by flashing AOSP roms. Just remember not to relock the bootloader because miflash can do that.

You must bind your mi flash to your account to be able to use it to flash a rom on your phone. Note that mi flash will recognize your phone even if you had flashed a different rom on it.

Mi Mix 2 MIUI12 rollback

Hi guys,
I need a bit of help. I updated my phone to Global Stable 12.0.1 via OTA. I'm not quite happy with it (auto dimming feature is quite bad, searching through settings takes ages etc..). I wanted to go back to MIUI 10. Is it possibile? My phone is completley stock.
Tnx for the help.
You need to unlock bootloader(7 days) and flash old tom in TWRP, no other possibilities.
If you can unlock bootloader, why not flash custom roms
