Mi 9T(davinci) Bootloader Unlock after Re-Lock help! - Redmi K20 / Xiaomi Mi 9T Questions & Answers

Hey there,
So, long story short i unlocked my device using the Mi Unlock tool, flashed a custom ROM, then after some time I re-flashed MIUI 11 and by mistake locked the bootloader. Tried unlocking it via Mi Unlock but it's useless as i receive this ,,This phone has been locked by -account number- and cannot be unlocked,,
Now, someone suggested that i should re-flash the system but this time to pick only re-flash and not re-flash w/ lock.
Device: Mi 9T (davinci)
Current OS: MIUI 11.0.4.0 QFJMIXM ( Android 10)
Recovery: Mi Recovery (stock)
My questions are:
1. Is this of any use?
2. I've heard this may cause a brick or the ,,system destroyed,, message, is it true?
Please,if anyone of you knows a fix to this or had this problem before and got a tutorial that i can follow, leave it here for me and other people to see.
Thanks in advance.

unlocked bootloader effects on ota installation or not

last time i unlocked my phone and installed another rom, but i dont like that. so i thought to revert to stock rom.
then i flashed stock cm12.1 , then again boot loader was locked.
then i unlocked bootloader only, so as if in any case i need to recover my data by rooting.
today i read a post on yuplaygod forums that they will release an ota soon,
i want to ask is there any problem if i install the OTA, any chances of device bricking or something else, because bootloader is unlocked, but phone is not rooted , everything else is true stock.
I sent my phone to service center when it has 5.1.1 of cyanogen mod and I don't know how they flash 5.0.2 of cyanogen mod it doesn't install any ota updates so I rooted and manually installed 5.1.1 officially by YU but the problem remains same. Can anybody help me.

Doubts on which guide to use to Update to Nougat and install TWRP

Hi, first of all, sorry if I mistype anything, as English is not my main language.
I usually try to find my answers in others posts, as I have installed custom ROMs and recoveries on other phones before (Nexus 4, Moto X 2014), but this time I couldn't find anything for my situation.
I recently imported an Axon 7 from Singapore, everything on the box is in Chinese, but when I booted the phone, the version showing on the settings is the A2017G, build number A2017GV1.0.0B10.
I tried to update from the settings to Android Nougat, but it says it is up to date.
Out of curiosity I restarted the phone holding power + vol up and booted the recovery, and it is all in Chinese.
I think the seller probably installed the A2017G Rom.
So now I don't know which guides should I follow to update my phone, I just want to have stock nougat and TWRP for precaution.
Should I just follow this one https://forum.xda-developers.com/axon-7/how-to/guide-install-twrp-unlock-bl-flash-t3517379.
Or this https://forum.xda-developers.com/axon-7/how-to/guide-how-to-unlock-bootloader-stay-t3461165.
Or just download an imagem from here https://forum.xda-developers.com/axon-7/how-to/download-center-factory-images-ota-t3606547.
I'm currently at work, so I won't be able to try anything right now, but any direction to what to do will be of great help.
And I didn't put my sim card there yet to see if the network works in my country, I'm from Brazil.
the first one.
do steps a then b.
dont do the c steps.
then reflash stock recovery, update to nougat, with stock rom, then reboot the phone in edl and reflash twrp 3.1 with axon-tool.
you will have stock with twrp
thanks for the reply.
I will try as soon as I can.

Yes sr.
You must unlock in b11 or older.
Then upgrade to b04, you must reflash stock recovery from edl or twrp. After that upgrade.
Then go back to edl and reflash twrp.
Note that for first unlock you have to flash the signed buggy twrp, and after unlock, you must flash 3.1 to have a working twrp.

How can I downgrade from Oreo to Nougat? (Want to unlock boot loader)

So I really want to install a custom rom and I know I need to unlock the boot loader and flash it with twrp. But I been reading around here and it seems unlocking the bootloader on Oreo is not possible and the only way to do that is to downgrade to nougat... except I don’t really know how to do this on my device since as previously stated, the boot loader is not unlocked and I don’t know where the stock rom for nougat is even available to download from, or any necessary tools to download to be able to do this (I’m a complete noob). Some info of my device: A2017u, Oreo, B20
Help would be appreciated, thank you
I think you may need to go back to Marshmallow to unlock bootloader and install TWRP but I'm not on an A2017U so won't try to advise you.
I did revert my own A2017G from latest Oreo back to Nougat ok. Since gone back to Oreo. It seems to work when stock but once you meddle with it that's when all the problems start.

Install GLOBAL firmware after root and unlock bootloader

Hello everyone.
I will give my wife my grade 7.
My redmi note 7 is rooted with magisk and twrp installed.
I would like to leave him a clean phone, without custom ROMs etc ... and with a recovery stock.
I would like to flash him a Global ROM from MIUI.
For that :
1 / Do I use Miflash to install a global firmware?
2 / Is it better to check the box relock bootloader? I read that this could lead to some hard brick xiaomi ?
thank's for your answer
Miflash? Why not.
Looked? Why
Unlocked. Maybe u can fix it!
Stock? Why?
Batterylfe?
Adaption?
Hello
Quick question about using a Firwmare MIUI stock version and OTA updates.
Can OTA updates be done automatically if the bootloader is unblocked (no root / stock recovery) ?
Thank you in advance.
