[UnBrick] Flashing Latest Stable ROM using Fastboot Mode

[Darklouis]

Bricked Device but has unlocked bootloader and having access to Fastboot Mode​

Before doing the process, make sure you have to remove your SdCard and having sufficient battery power to ensure that the process won't be interrupted and to prevent higher chances to hard bricked your device (Dead)

Requirements:

• Accessible Fastboot
• Unlocked Pocophone F1 Device
• Laptop/PC
• Type-C Data Cable (Not Charging Cable because it has no data output and input)
• Microsoft Visual C++ Redist 2015, 2017 and 2019 (Please report what kind of error you get when flashing and provide a screenshot)
• Fastboot ROM updated to 11.0.6.0 (get it here: https://bigota.d.miui.com/V11.0.6.0...M_20200227.0000.00_10.0_global_983cdd2f82.tgz)
• Qualcomm Drivers (Search in Google)
• Latest Mi Flasher (https://www.xiaomiflash.com/)
• 7-Zip to extract .tgz file type (This is more efficient and has fewer errors) https://www.7-zip.org/
• Patience and Hope

NOTE: FASTBOOT MUST BE ACCESSIBLE, IF NOT, THIS TUTORIAL IS NOT FOR YOU​

While Turned off, Hold POWER + VOL DOWN for a few seconds

1. Install the drivers needed (Qualcomm, Microsoft Redist 2015, 2017 & 2019)
2. Reboot your Laptop/PC to make sure all drivers are working
3. Using 7-Zip, extract the Fastboot ROM (beryllium_global_images...da212305c9.tgz) to any designated directory/folder
4. Open Mi Flasher
5. Click "Browse" and navigate to your extracted folder of Fastboot ROM
6. Select the folder that contains the extracted Fastboot ROM
7. On the bottom right, select "Clean All"
8. Now, reboot your phone to Fastboot Mode

Vol Down + Power Button

9. Connect your phone to your Laptop/PC

Mi Flasher should recognize your phone. If not, check your Laptop's/PC's USB Port, it might be broken. Try another port, from USB 3.0 to USB 2.0 If the problem still exists, try reinstalling your drivers. Some users faced problems on AMD system, try it on INTEL based system for more stability.

10. After all that, click Flash

The process should take about 5-10 minutes depends on what kind of Laptop/PC you have

11. If you see on the results tab "Success", then the flashing is completed
12. Now, try rebooting your device

The booting might take about 5-15 minutes, just be patient

Bricked Device but has locked bootloader, you applied for unlocking, and have access to Fastboot Mode

There might be a chance. If you applied for unlocking the bootloader, you can still unlock the bootloader by downloading the Mi Unlock Tool on their website https://en.miui.com/unlock/ and boot to fastboot mode and follow the steps provided on their website.

Bricked Device but has locked bootloader, you didn't apply for unlocking, and having access to Fastboot Mode

Your Device is HARD BRICKED. You cannot Flash your phone with a locked bootloader, if you cannot reboot or your device has bootloop after an OTA update, sideload, etc. you should bring your device via the nearest Xiaomi Service Center for further analysis.
You could do the flashing by using EDL Cable (Deep Flash Cable). Or by Testpoints to access EDL with locked bootloader. Find a guide anywhere in XDA or in YouTube.

Is the EDL mode is the same as fastboot mode? Afaik they're different

EDL or download mode term is used for samsung devices (uses ODIN). They are alike as fastboot mode (uses flasher e.g MI Flash tool, MTK flasher, qualcomm flasher, etc.)

Edl flashing means using a edl flash cable or hardware test points. It allows to unbrick a corrupted bootloader .

 

[Darklouis]

Edl flashing via this method doesn't require permissions or what since I heard edl flashing is locked and requires authentication .

Going to edit my post since that someone confuses about EDL and Fastboot.

And yes, only Xiaomi has access to EDL Mode (Emergency Download Mode) to force flash system images or firmware because they are the OEM of the device. Only Fastboot that can user be accessed but it requires an unlocked bootloader.
Theoretically as an user, you can access EDL Mode but it requires such tools and knowledge.

Why when I plugin my phone to miflash it only shows the option to unlock and erase data, rather than the flash function?

Please provide a screenshot so that I can know if what update of Mi Flasher you have

Oh no.. You downloaded Mi Unlocker, not Mi Flasher.
Please search in a MIUI Forum or Google "Mi Flash Tool"

Ya I figured. The problem though, is that your post is linking to miflash unlock tool while you say you need to download the Flasher
I ended up just googled it and got my flash back to miui successful

Wanna thank you for this post first. However I was unable to run the latest MiFlash due the error as seen on screenshot. (Windows 10)
No matter what I was trying to do, MiFlash was still asking to install drivers (including Nvidia drivers, wtf?)
USB drivers were installed correctly as I could see connected device with installed drivers and fastboot devices have also worked fine. I have done several reboots, windows test mode, but without success...

If anybody else is having same issue, I was able to use probably very old version of MiFlash to successfully flash fastboot MIUI image.

New and updated Mi Flash Tools needs new drivers (including Visual C++ 2015 or the 2017/2018 one, Microsoft Framework, etc. e.g. just like installing a game, it needs drivers to work)

 

[samexex]

edl required dfc cable/testpoint and auth mi account, no need ubl,,
and fastboot only need ubl..

That is correct and I have all of them installed, but still unable to run latest MiFlash properly.

Got the exact same problem with new Miflash. Tried the old version but it gives me an error. See screencap. The file it says missing is actually there.

The attachment went wrong. Maybe now

Edit:
Maybe you can see my attachment, ican't i dont get why.
Anyways Miflash sends an error message saying ' can not found file flash_all.bat '
When i open the tar file the flash_all.bat file is there.

Bootloader is open but USB debugging was off when the bootloop accured. ADB does not recognise device, older MiFlash does but gives error written above. Any idea how to proceed? Your help is much appreciated

Make sure you have the drivers installed.

Check it on "Device Manager" while the device is connected with fastboot mode on.
