Question Relocking bootloader - Xiaomi Poco F4 GT / Redmi K50 Gaming

Hi
I bought a second hand K50 gaming but working with poco f4 gt rom. If I proceeded to relock the bootloader, will that cause a brick doing so? And may I know why in simple way?

You can re-lock the bootloader only with a CN stock rom.

Are you 100% sure about it? I am aware that it has been like that for a good while now, the thing is that i just installed the lastest MIUI CN via fastboot. I have a F4 GT and its now showing device model as 21121210C which is for CN. The device model of F4 GT is 21121210G and i believe that would prevent from properly locking it. I think MIUI 13 would always show 21121210G no matter the rom you flashed but they may have changed it, perhaps due to too many RMA's.
Sadly im not gonna risk it to lock it since i cant really afford the trouble it could cause, if we ever get a leaked qfil programmer ill give it a go.

with BL unlocked not everything lol, wallet wont work just as a quick example. also it doesnt show as certified
he would have to lock it, which like i previously said i suspect wont brick it with a clean flash of current miui firmware, but cant guarantee it

Some guidance redmi note 3 pro before i commit to buy

Hi Folks,
Been reading alot of different threads and searching the net. I see some of the sellers on e bay have roms with google play store and multi languages pre installled. From what i gather these seem to be a custom rom and not the global rom. (which has me thinking is the bootloader unlocked on these ones?)
Are there any disadvantages to buying these? will the rom get OTA updates( probably not) ? will they contain more bloatware than the stock original rom?
So should I buy stock rom? Then upgrade to the Global rom for the english and to get rid of any chinese stuff on the phone?
If i want to install custom roms, then i gather the best way is to request via the mi link to have bootloader unlocked and flash to the developer ROM.
i have read a few different ways, users maybe bricking phones. So want to ensure I do things right from the start.
Any advice is most welcome.

1.bootloader is not unlocked
2.all phones,which don't come from mi.com have custom roms installed and you will not receive OTA upadtes in future,but you can install original MIUI Global Rom.It don't care if they contain bloatware,you will flash new rom
3.you don't need to buy sotware,it is free from miui forum
4.i don't recommend you to unlock bootloader and to install custom roms;too many people around us cry after this action.Stay with original rom and you will don't have problems
P.S:i suggest you to buy from trustworthy reseller and not from Ebay or untrusted sources,easy you can receive a fake device.
Thanks for the tips, one final question as a lot of the flashing process seems to be all over the place or conflicting information.
If I had a stock version rom and a custom rom , do both require for the boot loader to be unlocked to flash to the global rom? Basically I just want the global rom, that will get updates and just install google services . It's a phone for the wife. Don't want a lot of bother. So in just trying to force a reliable seller and gather whether I need to request to get the boot loader unlocked or not.
There is a way to flash roms with locked bootloader. Just having vendor rom doesn't necessarily mean the bootloader is unlocked.
Vendor ROMs or unofficial MIUI ROM might have malware/bloatware pre-installed. I myself prefer official ROM unless the customized ROM is from well recognized developer.
If you'd like to have global rom, then you should buy the redmi note 3 with qualcomm cpu, aka redmi note 3 pro.

You can install Global Rom even the bootloader is locked(mine is locked);global rom have google services preinstalled,you don't need to install nothing related to Google apps.The phone is very good and speedy and nice.One more timeON'T UNLOCK BOOTLOADER.Think a litlle and ask your self:Why Xioami had to invest more money in extra security?

Understand that falshing the China Dev Rom gains Root access. Tell me does it affect any future OTAs ? or warranty ? And does chinese spam appear ..
I just want root access and continue using my phone normally. ( and receive future OTAs) What would u recommend. ??

For native root you must have Unlocked Bootloader even on Chinese Dev ROM... it won't affect any future updates if you are not using any Custom recovery.
and in Chinese Dev ROM there won't be any Google Services pre installed and lots of Chinese app will be there... hovever you can remove them if you are rooted... but again you need to have Bootloader unlocked to gain root access... and it is suggested to not flash a dev fast boot ROM and flash Chinese Stable Fastboot ROM and then update to latest Chinese Dev.
MiPCSuite solve all problems, no need any CMD and fastboot. Save your information first - it's make clean installation!

Thanks my friend. But had a bad experience. I flashed the MI Chinese Stable Rom thru MI Flash. Sadly device got locked stating that this device id is associated with another device. Could not go beyond the startup menu. Could not even shut my phone. Went to the service center and back on Global Stable Rom. Applied for Unlocking permission. Approved by Xiaomi. However now the issue is that when connected, the phone is scanned upto 50% and then again this device is associated with another ID. So can someone pls help me.. How do i switch to a Chinese Dev Rom, get root permissions and get on with my life ??

Device locked after flashing Chinese ROM is strange...!!
I just unlocked Bootloader with Global Stable Then Flashed TWRP alka and then Flashed Latest MIUI CN dev ROM and all is working as it should be...!!!
now with Unlocking Bootloader...
the process is quite pain of a**...
it work sometimes doesn't work something, xiaomi needs to come up with better solution...!!
so far you can try each step from this guide
http://en.miui.com/thread-280561-1-1.html
and if it doesn't work try after 3- 4 days or even after week, it won't work if you keep trying each day. (strange but true)
after Unlocking you can either Install TWRP and install SuperSU to gain root access...!! but it will break Official OTA updates, you can still flash full ROM but OTA won't work anymore...!
EDIt..
you can try this without breaking OTA..

Official Global Redmi Note 3 3i Pro Prime Special Edition

Hello,
I have received of this particular Redmi Note 3 Pro Prime Special Edition (3GB Ram one).
It comes with MIUI Global 7.3 Stable 7.3.7.0 (MHRMIDE).
Now I see there are so many different guides and version and I would like to confirm before proceeding.
Essentially I want to unlock the bootloader and install custom roms (CM).
What is the best way to proceed?
Install Developer Edition (miui_HMNote3ProtwGlobal_6.9.29_f35a25dd3f_6.0) downloaded from http://en.miui.com/a-232.html ?
I am planning to do it via Updater application from the phone.
Have made a request via website for unlocking the bootloader. Anything else I need to do?
Thanks
Almost everything same with kenzo (RMN3 Snapdragon).

make sure you are signed into both i.mi.com and your phone using the exact same credentials.
I've unlocked mine probably a dozen times now, with some rom's locking and me reflashing over and over again. No issues, never got stuck at 50%. I've only ever used my email account to link to Mi account, never my phone number.

Upgrading MIUI 9 to MIUI 10 on an International Mi Pad 4

Hi!
Before attempting anything I wanted to ask this here:
I have a non-rooted, completely stock Mi Pad 4 bought from Gearbest. It is the international version (Model name: M1806D9W) that came with Google Apps, already with english language, etc. It currently runs MIUI Global 9.6 | Stable 9.6.7.0.0(ODJCNFD) (Android 8.1.0 OPM1.171019.019)
I read online that MIUI 10 should be available for global versions which I think mine is? But yet system updates tell me there are no updates available.
So here's my question: What is the simplest most straightforward way to upgrade to MIUI 10?
I see I can download ROMs from threads here and other places online but I want to make 100% sure of which one should I get.
Bonus question: Any way of backuping everything so I don't have to re-install, reconfigure, re-place my apps icons, etc?
Thanks so much!
pretty sure the international version that your reseller claim is false.. there are no international version now.. they probably loaded an "international modified" rom .. highly recommend you to flash xiaomi EU rom already comes with prebuilt playstore if you ur bootloader is already unlocked. if not, flash official chinese miui 10 rom and they are many guides to get playstore on chinese rom as well.

Ok I see! So once I upgrade to MIUI 10 I will have OTA updates then?
This is the one I need right? https://forum.xda-developers.com/mi-pad-4/how-to/rom-miui-10-xiaomi-eu-links-t3864882
Also is there any way of restoring my apps, settings, etc like it is on MIUI 9 right now? OR will I really need to start all over again?
EDIT: I don't believe my Mi Pad 4 is rooted. This seems like good instructions on how to root it and flash a new rom? https://en.miui.com/thread-3196420-1-1.html
Thanks so much!
i just flashed my mi pad 4 . It had the same rom, just modified rom to include the playstore,
The bootloader is already unlocked.
just boot to fast boot. volume key + power
flash twrp - i used twrp installer bat from here en.miui.com/thread-3196420-1-1.html
once boots twrp, then flash miui 10 - androidfilehost.com/?w=files&flid=281632
job done.

yeah the link is correct, with xiaomi Eu rom you can still get official updates, maybe just slight delay from official chinese stream. but that's the best support we have so far for international miui roms now. the check update seems to be quite buggy on xiaomi eu rom, sometime it downloads but fails on completion.. just try again.. 2nd try is the charm as always haha. if not you can download the rom and dirty flash no problem, i was on beta previously so maybe thats why.
highly recommend you to start from fresh.. migrating over apps may result in bug occurrence.

Back to official EU rom?

Hello. I came here for help. As i no longer focusing for phone rooting, i'm not able to switch back to stock rom for Mi 9T. Currently i have old MIUI 10.5 by xiaomi.eu 9.8.1 . I want to switch back to stock, most up to date version of ROM for this phone. I would like to ask how to do it. I'm pretty sure i need to update my firmware before flashing latest stock rom but i don't know which firmware. Can somebody post here up to date manual with steps how to do it? I also know about some MIUI program for Windows that can help but i saw many times it just hard bricked the device. I would appreciate some experienced user to tell me what to do.
I'm really sorry to ask here for this (newbie help) but as i said, i'm out of it for like 2 years now.
PS: It would be nice to don't have anti-rollback protection (just in case)
