Hi thanks for your response. Tried to do that but it needs authentication mi account, keeps failing everytime I go into it due to it being hard bricked. So it is an EDL issue for me.

My mistake not read properly. Try update manually, download rom then install via updater
[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] jceey15:
So 3 months after I got the phone, I tried to unlock the bootloader about 2 weeks ago, and got the timer (168 hours). Now when I tried to unlock it again, it's mostly giving me (Like 9.5 out of 10 times) a "Couldn't verify device: Can't get info" error at 50% or sometimes it does go beyond 50% and at 99% it will give me the following error (please see attachments).

I've tried everything from:

1. Re-linking my account in "Mi Unlock Status"

2. Removing fingerprints and lockscreen

3. Running unlock tool with admin rights

I don't know what to do anymore :crying:. If anybody could help that would be greatly appreciated
[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] gian1972:
Thanks, so you installed the rom downloaded from the first page too? Is this the filename you used? miui_RAPHAELININGlobal_V10.3.3.0.PFKINXM_a837ea77ac_9.0.zip

Does this rom have OTA updates? Because I see that now there is the 10.3.16.0... (https://sourceforge.net/projects/xi...files/xiaomi.eu/MIUI-STABLE-RELEASES/MIUIv10/)

[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] iXanza:
What do you mean it will not install? The stock rom overwrites the recovery Everytime you reboot the phone. You can flash magisk to prevent this from happening.

Can you share which patch used also how you root your device
[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] Hursty uk:
This worked for me but it might not for you think before you try it! your phone's life is in your hands not mine.

Make sure phones bootloader is unlocked and usb debugging is selected in developer options you will also need to know you Xiaomi account password for later.

Download minimal ADB and fastboot from page 1 of this thread and extract file to desk top then install but make sure you install file to you c:\ drive

Download unofficial TWRP.3.3.1 when downloaded rename it to twrp and move it to the minimal ADB and fastboot file that you just installed on you c:\drive

Download the rom of your choice

Hold volume down and power button on phone and boot into fastboot mode and connect phone to computer

On computer open the minimal ADB and fastboot files on the c:\ drive and click the CMD exe icon and this will open the CMD prompt window

Now type in order

adb devices (and press enter)

Fastboot flash recovery twrp.img (and press enter)

Now on your phone hold the volume up and power button and it will boot into twrp recovery (sometimes you might have to do a quick click of the power button to wake screen up) when in recovery select wipe then format date and type yes and swipe, now go back to main menu and press reboot then recovery now phone will reboot back into twrp recovery

now select wipe then advance wipe now tick all boxes apart from system and usb-otg then swipe, now go back to main menu and press reboot then recovery now phone will reboot back into twrp recovery

Now in twrp recovery select mount and make sure system has a tick next to it and your phone is connected to your computer , on your computer open your phone's storage and copy the ROM of your choice to it.

Now on your phone in twrp recovery main menu select install you should be able to see your ROM.zip you just copied over, select ROM.zip and swipe to install, once it's installed go back to main menu and press reboot then system.

Once your phone has rebooted and you have gone though the set it up, on your phone go to this xda thread and download the Magisk manager APK and install it, open the Magisk app update manager app first if it needs it then click install Magisk and download the zip file. Now hold volume up and power button and boot into twrp recovery at main menu select install you should see the Magisk zip select it and swipe to install now go back to main menu and press reboot then system, when phone boots up go to Magisk manager you should see to green ticks just tap safety net and you should be all rooted.

To solve sound issues YouTube if you have them depending on what ROM.zip you installed, open Magisk manager and go to downloads and search for audio compatibility patch then click to download, now reboot into twrp recovery click install and select the audio zip and swipe to install go through the yes and no options using your volume key when your done reboot device.

Any call issues disable Google assistant.

Hope this helps you mate :good:

I have the miui 9.5.31 beta with unlocked bootloader (aka fake global)

Can i skip converting to chinese rom and just flash the latest stock rom? (Go ahead from step 23)

My understanding is a similar procedure should have been done to flash this 9.5.31 beta rom
[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] Hursty uk:

Hi everyone. Please help, I am stuck in Fastboot and it wont boot into TWRP nor the System. This happened after I restored a backup of the System partition using TWRP.

Anyways, Im trying to flash the official stock ROM and I always get the "Mismatching device and image" error. I downloaded the 3.8.0 Fastboot btw.

Please help, I'm very desprate :(
[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] gian1972:
Here is what I suggest you to do but only if it is unlocked. This is only the method as I'm not in front of a pc I cannot give you exact commands but you can search...

Go in fastboot and connect the phone. Then via adb load the latest twrp.

Download the latest stable from miui.eu (10.3.16.0) and copy it via adb to your phone.

Reboot in twrp and clean all and flash the zip

Hope this helps

Is the ROM your trying to install a extracted .tgz file?
[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] jceey15:
I extracted it from a the zip file and then exctrated it again. Currently its now a folder
[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] DaveHTC200:
For me it was!
[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] Hursty uk:
You can't flash zip files with Miflash it has to be an extracted .tgz file ! You need to download firmware global stable 10.3.3 recovery from page 1 of this thread . It is a tgz file , when download you need to extract it (you might need to download a program to do this) once you have extracted the file copy it to your c:\ drive but you must rename it so rename it raphaelin so it looks like this on your c:\drive

C:\raphaelin

Now flash that file through Miflash

Make sure you select the right option at the bottom of the Miflash tool before flashing! I would select clean all then flash.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] jceey15:

Yes that looks right file but looking at the name of the file in your picture it's to long you must rename the file just to raphaelin before you flash it.

i found in an earlier comment that you say the rom has .tgz extension and it should be renamed

however after checking the links in page 1

Firmwares

Global Stable

10.3.3.0 Fastboot --> zip file [what I downloaded ]

10.3.3.0 Recovery--> tgz file!
[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] Hursty uk:
(That's strange the .tgz file I download a couple of days ago was named fastboot?)

Yes I'm sorry it's the recovery it must be the .tgz file you need to download , when it's downloaded right click on it and extract it to your c:\drive but change the name of file because it's to long to install change it to c:\raphaelin then install though Miflash.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] jceey15:
I tried flashing twrp, and it did manage to flash, but when I hold down the power button + up volume, it would just go back to fastboot
[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] Robbo.5000:
First, you are trying to flash the wrong image to the phone. If you have a Chinese phone, then flash a Chinese fastboot image in the Mi Flash Tool.

Try getting the phone working before installing an Indian (global) ROM.

Second after flashing TWRP and when in fastboot still. Press and hold both power and vol+. Keep both pressed while it boots and until the phone vibrates. When the phone vibrates release power but keep pressing vol+
[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] jceey15:
I did try the China fastboot image, both 10.3.6 and 10.3.8 China Stable Fastboot Roms and I get "Mismatching of image and device." When I flash TWRP, it manages to send the recovery, but when I hit on power + volume up, it still goes back to fastboot
[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] Robbo.5000:
Do you have an Indian phone or Chinese phone?

Booting to TWRP from fastboot isn't straight forward and can be a little tricky, follow what I've said in the previous post.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] jceey15:
I have a Chinese phone, sadly :(

Which post is this, if you don't mind? :)
[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] Robbo.5000:
Four posts up from this one. Follow what I've said about booting to TWRP. If you just keep holding power and vol+ it boots to system. You need to release power first, but at the right time.

Also look in this MIUI guide http://www.miui.com/shuaji-393.html

It's all in Chinese, but don't worry about that. It contains all the latest fastboot ROMs. Scroll down to the bottom of section 1 and you'll see K20 Pro then some Chinese text then Fastboot. This is the link for the latest fastboot ROM - should be 10.3.16

Try flashing that.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] jceey15:
Thanks for this, I'll try this later on and provide feedback :)

For TWRP, so I let go of the power button when it vibrates? Because in my end, when the phone vibrates, it displays the Redmi logo for about a second or even less, and then immediately goes into fastboot
[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] Robbo.5000:
Yes, after installing TWRP in fastboot mode, when rebooting into TWRP, let go of power as soon as it vibrates, but keep holding vol+.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] jceey15:
Thank you so much, I'll definitely try this later.

Wipe data, cache, dalvik and then try installing the latest recovery ROM, that's in this threads first post.
[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] jceey15:
I'm 90% sure of the answer, but I just want to be sure. After wiping data, cache, and dalvik, I install the recovery ROM immediatlely, right? Not Wipe > Reboot > Install > Reboot?

Guess its time for me to accept my fate :crying:
[Redmi K20 Pro / Xiaomi Mi 9T Pro Guides, News, & D] Robbo.5000:
OK, I assume you've got adb and fastboot on your PC.

Copy your TWRP image into the adb/fastboot folder on the PC then rename it TWRP.img.

Boot the phone into fastboot and connect to the PC.

Open command prompt or power shell on the PC

Navigate to the fastboot folder then type

fastboot boot TWRP.img

This command will copy the TWRP image into the phones memory and boot it from memory, so it's only temporary.

If things go well the phone should boot into TWRP.

At this point try what was suggested earlier, i.e. Wipe data, cache and dalvik, possibly wipe system too, then install the latest official ROM.
