K20 Pro bricked

Hi guys,
I have just read a previous post from "abdulmaalik1tt" about a problem after an accidental bootloader closing. I have a similar problem but in my case, I think it is harder.
I intentionally closed the bootloader after installing everything in my K20 Pro, but I didn't know that if it is closed by other one than the one who opened it, the phone will brick.
I tried to unlock again, but in 99% the app gives me an error, and ask me to change something in developer options. Obviously, I can't do so, because the phone doesn't boot.
I tried to use miflash but it gives me an error because the bootloader is now closed
Is there a way to unbrick my phone? Should I throw it away through the window?
Thank you in advance.

same case, you open the back, do test point method, if you Mi account is not EDL authorized, you can borrow, or call the guys that help many k20 pro user in XDA.

please help
do you get any solution to this case? i have the same issue.

I had the same problem. Sadly the only thing you can do yourself (it's also the fastest and cheapest option) is to open your smartphone, short the two EDL points on the motherboard to access the EDL mode, contact someone with an authorized Xiaomi account to input his username and password in the Mi Unlock tool (through Teamviewer) and enable you to install the stock Chinese firmware.
The only other option, sadly, which I didn't like at all, is to send it to a Xiaomi service point.
And all of this because the default option in the Mi Flash tool is "install and LOCK". Idiotic.
PM me if you need the contact of the guy with the authorized acc.

if you can boot in fastboot try unlock bootloader with miflash unlock but old version it work for me later unlock bootloader you can flash stock with miflash again

I am in same boat - fake global rom, flashed forgetting to set to Clean all only - so bootloader locked.
Seller is no reachable - so looks like this is my only way.
When you guys say 'short' these two pins - how did you do that? with a paperclip? and you mean from one pin to the other pin?

--Update for future reference of others---
My K20 Pro has been restored with help from the Russian contact provided on previous page - ask nicely, he is very busy so don't waste his time.
My experience was great, he was patient, we made appointment time over whatsapp, we have to try twice as i couldn't get into EDL mode (try a different pair of scissors or tweezers).
Once in EDL he logged into his mi account via my team viewer session and flashed the rom i has prepared (chinese original fastboot).
Right after flashing - had a bit of trouble booting up the first time, it didn't boot when pressing the power button (no usb cable), when i plug in USB cable - it showed 100% battery but also didn't boot. Had to play with disconnect then reconnect the battery THEN unplug cable. And it finally booted the first time.
Thank you guys!

I ended up blocking the bootloader accidentally giving my k20 pro when changing the rom, but when passing the rom by edl, the device does not turn on in any way, when passing the Chinese rom I have to block the bootloader?

Worth Checking out he thread, maybe older mi unlock can remove the bootloader flag for you ? cheers

Bricked Redmi K20 Pro, stuck in Recovery Bootloop

After trying all kinds of roms from here, I decided to go back to basics and flash a global stable ROM.
In the Mi Flash software I forgot to check the "Clean All" button, and left the default(I don't know why this is the default) "Clean All and lock"
Now, I'm stuck in a recovery(can go to fastboot as well) bootloop, can't even turn it off unless the battery dies. It says at the bottom : "This MIUI version can't be installed on this device"
I'm unable to flash it again using mi flash, unable to unlock it again as it gives me a weird chinese error, that translated, it think it says : "This phone has been used by account 622****418, by looking for phone lock"
Unable to boot into EDL, tried with a deep flash cable(seems it is not supported anymore)
I didn't open it, as I still have warranty(just bought it 3 weeks ago).
USB Debugging and OEM unlock are off as it was just flashed so it has default values.
The account on it is mine, but apparently mi Unlock is not recognizing it. My Mi account has different digits and I have permission to unlock the bootloader since last year.
Is there any way that I can go around this ?
I'm thankful for any advice that you have, guys...

Your device is most likely permanently bricked - when the bootloader is locked with a global ROM on a Chinese Xiaomi phone, nothing can be done to fix it - except one thing.
Are you sure you're booting into EDL mode correctly? I think you need to short two points on the main PCB while plugging in a USB cable. Xiaomi has a proprietary implementation of EDL mode - IIRC you need special Xiaomi software and a Mi account with the appropriate permissions (you can beg Xiaomi for permission on the Mi forums, or buy a working account from someone online). In EDL mode, you can re-flash the China ROM and recover the device.

Most likely, that's what I'll have to do, but I wanted to consume every chance and tutorial online before I remove the Back glass...SO it's Service Center or Test Point with auth accounts, which it's hard to get. I rather pay. Just wanted to make sure that it's bricked from my perspective, like I can't do anything to fix it from my end. Thanks

There is nothing you can do, the bootloader is now locked and you are on a rom that's not matching.
I used the Russian tech reported in one of the other threads about bricked k20 pro, costed me $20 and I needed to open up the phone, and do test point edl which were all easy and well worth it to save the $650 AUD I paid for the phone.
https://forum.xda-developers.com/k20-pro/help/destroyed-error-fastboot-locked-t3946012/page6
just add him on whatsapp and be nice to the tech and he will help you. I saw other posts if you ask him like an ass then he will ignore you.

I definitely don't want to open the phone. If it comes to that, I rather pay someone to do everything with proper tools and software.

You know, try to get in touch with xiaomi support. Explain The case and maybe they unlock it for you from there.

Hey Bro

Did you find any solution without edl method? Cause currently I'm facing the same problem.

The only solution here is to go into EDL Mode, if you dont have an authorized mi account, I recommend s-unlock.com they have an automated service and their own tool to flash your phone, go check them out. If you have doubt opening the phone, it isnt hard. Just use playing card first and dont remove it, then find an old credit card to continue further gently.

After removing the back of my phone and fixing it with the help of an awesome dude from Japan found on whatsapp...I tried to unlock my bootloader again, and realised that the account I had in my phone was not the one that I was entering on miUnlock. I couldn't see that because the error message at 99% was in trad Chinese.
Maybe it would've worked if I knew that. If you go into Fastboot and try to unlock it, what message do you get?

Stuck in fastboot mode.

Hello,
Just after receiving my new Redmi K20Pro Premium Edition, I tried to change the China ROM to the K20Pro Indian one, with the hope to use Netflix and GPay.
I used Adb, fastboot and Miflash as recommanded. Everything works well. The phone bootloaded again but stopped on Main menu with this message :
"This MIUI version can't be installed on this device".
There, nothing worked anymore. the fastboot oem device-info says the phone is locked.
To unlock using Miflash-unlock I need to modify the Mi status of my Mi account in the phone. Impossible to do if the phone does not bootload...
If I try to flash a new ROM (China Raphaels specific for K20pro Premium) the Miflash program blocks because the phone is locked...
I do not know how solve this blockage.
Could you help me?

Don't know should you search now for a paid help by EDL authorized user, or is there an easier way
But in MiFlash, at the bottom/right, there is the default option: Clean all and lock, you should have checked-in instead: Clean all
Most users just want to flash (and clean) without relocking, and every week somebody similarly bricks his Mi 9* - if he/she didn't miss the default relock option, he would still be able to flash a proper firmware to safe his phone, but with the relocked bootloader he is f* up with no second chance
Don't know why developer(s) of MiFlash implemented the 'wrong' option for default - but the hook is there for long time and it keeps the EDL authorized helpers busy ?

Thanks. It what I understood a little bit too late.
Do you know how to contact a EDL authorized user?

Search (here) or ask.
They usually use T...gram accounts and such posts are not permitted (albeit users like you do need help, it's meaningless to dispose the bricked phones to garbage just like that).
If you are quick enough, you will find the contact before the post gets deleted?
If you are already on some T..gram support group for Xiaomi, safely ask there

Redmi 4x unlock

Hello,
As second phone I've got a Redmi 4X from my father. Phone cames with the China ROM, I would like to upload the Global ROM. In order to do this I've got to unlock the phone.
On Dev options, Mi Unlock Status function, I always stuck on the message "Don't disconnect from the network, sign out of your Mi Account, perform a factory rest, or erase system data. If you've already done any of the above, add your Mi Account again; otherwise, you won't be able to unlock your device."
I've try what the message says, no luck.
I suspect it's something blocked on the Xiaomi servers about this phone. Anyone can fix it?
Thank you!

I've solved putting the phone in EDL mode using the test points on the board.

Redmi K20 Pro - This MIUI version can't be installed on this device

I have a Redmi K20 Pro 8GB RAM 256GBROM
It came with a 12.0 Global MIUI
I ran the bootloader unlocker from Xiaomi, it worked the first time
Then I flashed it with: miui_RAPHAELGlobal_V12.5.2.0.RFKMIXM_edbf5f63e8_11.0.zip
It locked the bootloader.
I now only get the menu: MIUI Recovery 5.0
I can no longer run the bootloader unlock, it fails on the second step and says "Please add your account in MiUI's Settings > Developer options > Mi Unlock status. The phone won't boot even using safe mode.
I don't remember if I ever signed in to the phone with my Mi account, I suspect not.
I'd like to confirm that I used the right ROM, does the K20 Pro and the 9T Pro use the same ROM?
So how can I unlock the bootloader?
What do I need to flash on this to go to 12.5. I don't use What's App so I don't care about those issues.
Is 12.5 and option? If not where can I get the latest ROM I can use?

Supposidely you used Mi Flash. You have two options there, like Clean All and Lock (unfortunately, offered by default) and just Clean All
Apparently you overlooked and left Clean All and Lock and as a result you locked your Bootloader
That's a common mistake and the way many people brick their phones. If anything goes wrong while flashing (wrong firmware, error in download, problems with cable, whatever), the result will be:
- phone cannot boot because of that error in flashing
- you cannot flash again since you already re-locked your Bootloader
Fortunately, I have no first-hand experience but I've seen many similar posts/questions and answers
AFAIK, you have two options now.
One, to look for somebody with EDL authorized account to remotely flash and unbrick your phone.
It will be a paid service and due to the XDA policies all posts providing such contacts are purged from XDA. You have to look to eg Telegram support groups to find them
The other option is in finding and using the so-called firehose file and method.
Tthat way you could unbrick the phone by yourself but you really need to google and/or search on XDA to find more details about
Sorry, that's all I could help you
