A little help in locking the bootloader again ! - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

I'm currently on latest stock MIUI Global 12.0.2.0 (Indian variant) with orange fox recovery installed and using few magisk mods. Now I want to claim my warranty due to some speaker issue, so have to relock the bootloader before that.
Can someone let me know the correct way to relock it and install the same stock 12.0.2.0 (Indian variant) without bricking it. Coz well i'm not sure if just directly flashing the firmware through MIUI flash tool using 'Clean all and lock' will do it or brick it as there are some forums on xda stating that can brick the device.

If you have an Indian K20 Pro, then you can safely flash the Indian MIUI fastboot ROM, using 'clean all and lock' with the Mi Flash Tool. You only brick the phone when cross flashing regions, it's OK when flashing the correct region.

Flashing Global Rom from Russian Global Rom

I just received my phone today and it came with unlocked bootloader and Russian global rom V9.5.14.0.OEARUFA.
Question is, can I download the updater ZIP file of Global Rom V9.5.13.0.OEAMIFA and use the updater app to flash instead of using Fastbook/Miflash Tools. Is this a safe way? Will it work? Thanks in advance!
Note : It is China Mi8 device.
I also wait for solution... Buy online and got russian rom and unlocked bootloader... What suitable twrp version for this rom because i scare bootloop will happen when install the unsuitable version... And does anyone here already try the miui pro rom from miuipro website.. does it good? Any feedback is appreciated..
The latest recovery-TWRP-3.2.3-0806 will do the trick.

Flashing with twrp is probably the safest way as mi flash you can accidentally re-lock your bootloader.
Since the OP phone is china mi8. It's compatible with all the rom in this forum (EU, global, etc) with unlock bootloader of course.
I do not wish to change my recovery to twrp. So it's the only way is to use miflash tools? No direct zip flash global from from updater app from phone ?

To my knowledge you can't change channel with updater app. With channel I mean Global stable, Global developer, Chinese stable, Chinese developer etc etc.
So global and global Russia can be used with updater app ? Is that correct?
But if can't, it will only show error and nothing will happen to y device right?

Magisk is probably tricking the firmware to see the bootloader is locked. For purposes of online banking and stuff? I believe bootloader is still actually unlocked.

Flash Global Developer via Recovery locked Bootloader

Hi everyone
First, I didn't find an answer form my question via search. Sorry if there is already one.
I'm now with an Global Mi 8 with Global ROM MIUI 9 9.6 (9.6.4.0 (OEAMIFD) and locked Bootloader. That's how my MI 8 got out of the box (so, the official Global version).
I want to flash the Gloabl Developer ROM 8.8.30 from the official MIUI Homepage (http://en.miui.com/download-346.html). As there is also a ZIP ROM Version for flashing via Recovery I want to ask wether it's safe to flash this. The verification process said no problems, just that all Data is erased. This is ok.
Is it safe to flash this way or is there a danger for a brick if the Bootloader is not unlocked?

It's safe to switch from global stable to global beta rom thru the updater, it won't brick your device.

Hello,
I was in your case with the same version.
No problem for me, I downloaded the version like you via the link then going through system update of the phone.
My bootloader is not unlocked
I'm currently on China Stable (miui9), bootloader isn't unlocked yet, what would happen if I flash globlal beta rom (miui10) (zip) via updater recovery?
It worked. Thanks

If your device is Chinese, you gonna brick it without unlocked bootloader.
So unlock it, flash then stay unlocked.
Is it possible to downgrade from 10 beta to stable 9 with recovery rom?
For the people who did. Did it erase everything on the phone? I am thinking of trying miui 10 but am too lazy to re-setup everything

Yes, it erases everything, back up all your data first, and save it on your computer
Hello,
I would like to flash Global Beta Rom on Global Stable rom thru adapter, but after touch 3 dots I do not have opportunity to choose the zip.
Do you have any suggestions how to do it?
Hello.
Click 10 times on the miui10 logo and submenu will appear.
Have fun
Thanks, it works :good:

I have two problems with ROM Global 9.5.31 Beta

Hello guys,
I buy k20 pro, I think its a China version. And i have two problems with this rom(Global 9.5.31 Beta), i dont know what i need do now.
First problem:
Reboots from nothing, sometimes the phone reboots when i use the finger for unlook.
Second problem:
Network(4G) stops to work from nothing and i need reboot for back to work again.
If I need change the rom, what rom i can use for this version? Its easy to change?
Sorry for my english, i dont speak well. Thanks
K20Pro doesn't have any Global beta rom, so your device came with a fake rom. What you need to do is to flash official rom via fastboot. Careful to select only "clean all" option for fastboot flash. Locking the bootloader may brick your device.

The Official Rom for your phone is China Rom. You can download it from MIUI China Forum. However, incase you need Google Apps, you’ll need the 9T Pro Global rom which works just fine on K20 Pro as more or leas they are siblings. Here’s the fastboot link for Global rom. Flash it via Mi Flash and choose the options carefully in the tool. Locking the bootloader would hard brick your device.
http://bigota.d.miui.com/V10.3.1.0....XM_20190805.0000.00_9.0_global_135788d537.tgz
Remember if you flash the china rom, you can lock bootloader, there wont be any issues. But if you choose to flash global/eu/india rom, locking bootloader will brick your device. So choose "clean all" in the flash tool.

Yes. If you use the Mi Flash Tool do not lock the bootloader, you will brick the phone. Make sure you choose the 'clean all' option.

You can get the latest fastboot ROMs from here
https://xiaomifirmwareupdater.com/miui/raphael/
If you change your mind and want to go back to the Indian ROM get it from here
https://xiaomifirmwareupdater.com/miui/raphaelin/
Here's the flashing guide from the official MIUI forums
https://c.mi.com/oc/miuidownload/detail?guide=2
You will need to view the page in desktop mode if viewing on a phone. Make sure you change the flash option in step 5 to 'clean all' before flashing.
Here's some detail from the official forums on when you can and can't lock the bootloader when cross flashing.
https://c.mi.com/thread-2584760-1-0.html
Global here means all versions that are not China.
Many users have cross flashed Indian phones with a Chinese ROM. The only problem will be if you forget to change the flash option and lock the bootloader.

Use this guide for flashing the MIUI 12 beta ROM.
https://c.mi.com/oc/miuidownload/detail?guide=1
Again it needs to be viewed using desktop mode if on a mobile.
I'm not sure if you can flash directly over Indian MIUI, you might be able to. To be safe you could fastboot flash the latest China stable ROM first. Or ask in the MIUI 12 beta thread if it's safe to flash directly over Indian MIUI, maybe someone has already tried.
I'm using k20 pro indian varient as my primary device.
Note: I don't have any secondary device.
I want to use miui china rom on my device for daily usage.
Is that safe?
Will banking apps works?

The Mi Flash Tool always defaults to 'clean all and lock', which will lock the bootloader after flashing. You MUST change this to 'clean all' before flashing, otherwise you will hard brick the phone. If you remember this, then it's safe, if you forget then it is not safe.
Because you can not lock the bootloader with the Chinese ROM installed, SafetyNet will fail and banking apps will not work.
In order to get around this you will need to install Magisk.
This guide tells you everything you need to know on passing SafetyNet and getting banking apps working.

You don't need to open the bootloader to get rid of the Vodafone ROM.
Just use the XiaoMiTool, follow the instructions and flash the Global or EEA ROM.

I have debranded my Mi11 from SFR (french operator) to Global EEA: you MUST unlock bootloader. Then, flash ROM with MiFlash and, if you want, relock the bootloader. Unlocking bootloader wipe internal storage.

False, flash EEA Branded ROM EU?? to EUXM (Global EEA) is like flash a ROM to an another Canal (EEA / CH / GLOBAL / TW etc...), ROM don't have the same signature so it's a mandatory to unlock bootloader for flash / erase ROM to EEA Global.
After that, yes you can flash full EEA rom/update directly from the system.

Can only confirm that.... As mentioned
How can you even think to flash your phone without unlocking your bootloader? Obviously you MUST unlock it. Then you can flash what you want.

I though if i flash official rom without changing region...aka eu to global i could....and even senior user mentioned its possible i tried....
Probably you missed the fact that the EU rom is a custom ROM and so not official. The only official ROM you can install is the one your phone come preinstalled with. All the others official or not, are not flashable without unlocking your bootloader

No... EU ROM is the Global EEA MIUI Genuine, you talked about Xiaomi.eu rom (Custom MIUI).
You know here a lot of people have some good knowledge.
And you can upgrade without unlock bootloader when it's the same ROM/Country (EEA/TW/MIX,CH etc).
In this exemple @Hunteres can't flash the lastest EEA ROM 12.5.4.0.RKBEUXM under system (on the fly) because he have a vodafone EEA ROM 12.X.X.X.RKBEUVD (phone with custom vendor partition, custom settings and pre-installed apps from carrier)

Hi.
Yeah that absolutely fine with stock EU with mi flash. The bootloader can be locked also on the new stock ROM. I think the only way you will brick is if you accidentally enable anti-rollback and relock. But yeah I done the same thing reflashing over VF ****ty rom and relocking.
