chinese rom with locked bootloader to global rom possible?

Hello all,
Yesterday I received a k20 pro from china with an unlocked bootloader.
I wanted to get rid of the spy/bloatware so i went and tried to install twrp to install another ROM, but for some reason TWRP flipped when i installed it (i think i forgot to turn off encryption) and just decided to stop working altogether. Recovery did not work anymore and so i was stuck in fastboot (bootlooping). After some stressfull googling i found out, the only way to get the phone working again is by flashing the (only) fastboot ROM, which was the chinese variant.
I was so stressed out, i forgot to change the flash option in xiaomi flash tool to "clean all" instead of "clean all and lock"(which is the default, fu Xiaomi).
So now my phone has a chinese ROM and the bootloader is locked.
So my question is:
Once i get the bootloader unlocked again (which will take 1 week hopefully), will i be able to install the global ROM (once it is released) or a better, a non-spying ROM?
Also, i tried debloating the chinese rom, but everytime i apparently debloat too much and the phone just stops working and i need to do a reset.
Does anyone have a proper list of xiaomi applications that are safe to remove (trough adb)? the ones i found remove too much.
Thanks in advance.

Yes, once you unlock your bootloader again, you can flash indian global firmware, which has less bloats, google apps and services included, and poco launcher.
For debloating cn rom, there is a tool here, I'll find and link.

May use this for debloating- https://github.com/Saki-EU/XiaomiADBFastbootTools

Hi, this is the program that i've been using for removing the xiaomi apps, however when some of the listed apps are removed the phone won't be able to restart anymore and i have to do a reset.
For now, i manually removed all the removable spyware by hand and installed blokkada to deny communication to xiaomi servers. I don't dare to remove a lot of system apps trough adb anymore since i had to reset my phone 5 times already... i just want to use it now...

Just endure the pain until bootloader is unlocked again then move over to the Indian rom, its much more tolerable.

This is the safest option. Whilst waiting for bootloader unlocking I just uninstalled anything that could be and disabled anything else that could be disabled. There were still many things I wanted to remove that could not be uninstalled or disabled, but decided I could live with them for a week.
After your week is up, you've got many options. If you like MIUI but not the bloat and spyware, then there are MIUI custom ROMs that remove the junk, xiaomi.eu ROMs being one of the biggest. Otherwise there are AOSP based custom ROMs that are stable enough to use.

Hello, I have a cruel doubt. I was really wondering if after I unlock the bootloader (I have a Chinese rom) doing Global installation I can lock the bootloader? Because you have this possibility and I believe we received normally correct updates, can anyone help me?

NO.
If you try and lock the bootloader with anything that is not the original region you will hard brick the phone.
If you have a Chinese phone, then you can only lock the bootloader when installing an official Chinese ROM.

I think only the account used to unlock the blootloader can relock and re-reunlock it.
If you lock the phone, you won't be able to unlock it again with another account.
It is just a safety mechanism from xiaomi.

You don't need an account to lock the bootloader.
Provided that there is not a Mi account linked to a phone, then anyone who has the phone in their possession can unlock it.
When people have bought a phone already unlock, then accidentally locked it, they have been able to unlock it themselves if the seller has already unlinked the phone from the sellers Mi account

So basically it is possible, if one gets a k20 pro flashed with global rom, that if the seller forgets to remove his account from the phone, you're stuck using ONLY other roms? In other words, in order to relock the bootloader and install official chinese rom, you need to contact the seller and ask him to go on his mi account to remove your phone?

Yes there has been a few cases on these forums where this had happened.
However, you can still use official MIUI ROMs, you can still flash the Chinese ROM and lock the bootloader. The problem then is that you cannot unlock the bootloader again if the phone it's still linked to another account.
If you buy a Chinese phone with a global ROM, why would you then want to flash a Chinese ROM and lock the bootloader? You would be better off just buying the phone still with the Chinese ROM and locked, if that's what you wanted.
People have had problems because they've been flashing an official ROM with the Mi Flash Tool and accidentally left the flash option to flash and lock. When flashing with the Mi Flash Tool you just need to remember to change the default flash option every time you use it.
If you never relock the bootloader, then you will never have this problem and can still use official MIUI.

I actually have another one. Can I install bootloader-unlocked update pscotes in the global rom on k20 pro without losing files, or everytime I have to install full rom?

I'm not sure what you're asking. I'm guessing pscotes is a typing error.

Bricked Mi 9T Pro

Hello. I flashed Global ROM over European ROM. my phone bricked, system and recovery is destroyed, I have only access to fastboot. I tried to unlock it and mi unlocker tool says I need to wait about 120 hours. My question is, will it unlock after that period time even when the phone is not in use and turned off? Because I don't want to open the back and pay for EDL flashing. Thanks.

As far as I know it should unlock OK. I personally haven't done this, but there are accounts on these forums of others who successfully unlocked the phone after the wait period in the same circumstances as you. If you were going to have problems you wouldn't have got as far as getting the wait period.

Your bootloader locked itself when flashing? Or you ticked to lock bootloader?

Cannot update my K20 Pro - please help

Hi all,
I bought my K20 Pro on Ebay and later found out, that the seller has unlocked the Bootloader and installed a Global Beta Rom on it. In detail it is the Miui 10 Global 9.5.31 Beta, Android version 9 PKQ1.190223.001. Now I do not get any OTA updates and have a security level still of May 1, 2019. If I try to manually download and install the latest update I do only get error messages. Can someone help me to solve this problem pls.

Flash firmware via fastboot and mi flash tool but don't re-lock your bootloader because apparently your phone is china version and after locking bootloader with global rom you'll brick your device. Next time double check from who you're buying a phone.

It depends on your OS. But mostly you need to have adb/fastboot drivers. Check also Device Manager if it's correctly installed.

Makes no difference.
Boot the phone in fastboot mode and connect it to the PC.
Check your PC can see the phone correctly with the
Code:
fastboot devices
command. You should get a response showing an ID number of the connected phone.
If your not sure about the above 2 steps, do a bit of research. You'll very quickly find informally about these things.
If you get a valid response to the above, then the Mi Flash Tool will be able to see the phone now.

You might be able to update from Global Beta to Global Stable using the local update method since your bootloader is unlocked. There's also no chance of accidentally relocking your bootloader and bricking your phone but since you are supposed to be running the China/India ROM with your hardware you might get an error message.
I think flashing via MI Flash is a better idea because the shop that scammed you might have also installed malware or Spyware on your phone in addition to the Global ROM. They also could have installed a modded ROM coded to prevent MI Flash from recognizing your phone.

Not recommended at all. Very likely to have issues afterwards.
It's considered safe to do this going from stable to beta, but it's recommended to fastboot flash if going from beta back to stable.

What do I lose when I open the bootloader Redmi K20 Pro

Hi everyone
Question for professionals and experienced people I hope to get a reliable answer on this matter
1- What do I lose when opening a bootloader other than air update and payment and warranty service?
2- Is it possible to return to the official status and receive air updates?
Thanks everyone in advance

Can't say for sure but you should still get OTA; if not you'll get full ROM zips delivered via OTA instead of the smaller chunk/patch updates.
The main thing is banking apps and Google Pay. Widevine should be OK. On mine it's L1 so still A-OK for Netflix/etc.

OTA updates work also if bootloader is unlocked. Idem for payement and warranty service...
If you root the phone it isn"t the same story.
Mine is rooted and OTA updates work. I download the update BUT I unroot the phone before installing it.
It"s possible to relock the bootloader but no need to do that...
PS: Unlocking bootloader resets the phone (Back up what you need before).

Unlock bootloader means no more hd on netflix n stuff.
Widevine stay L1 but netflix will failed to load unless you delete smthing n widevine drop to l3

Could you express your problem in a little more detail? Like what recovery mode? And why do you need to wipe data? What errors do you get?

first important things: your phone is full stock? i suppose you have installed magisk with some modules. try entering in fastboot mode and ser your current active slot. switch to other slot and try reboot. but if u have a data backup, best solution is a full clean flash of full stock firmware via miflash or other tools
edit:u can also try reflash stock boot.img and vbeta.img with dmverity check disabled. seems a boot.img problem

Hello, friend, I have the same problem as you, and it is completely compatible with your mobile phone hardware model, the same is M2103K19C Maybe the Global version model is different, so it cannot be updated, but not necessarily, the solution, do not update, Wait for the next version and try again, MIUI will launch MIUI13 update
