How to flash Xiaomi Xiaomi Redmi K90 Pro Max / POCO F8 Ultra

  1. If you have Fastboot firmware, the extension must be “.tgz.” If it is not in this format, rename it from “.gz” to “.tgz.” You can extract it using WinRAR.

  2. To work with Fastboot firmware, download the latest version of XiaomiFlash. After downloading, extract the tool.

  1. Open “XiaoMiFlash.exe.” Install the required driver if prompted. Click on “select” and choose the firmware/ROM folder that contains the “flash_all.bat” file.

  2. Ensure that your phone’s bootloader is unlocked. If not, you’ll need to boot your phone into EDL mode (9008) for flashing.

  3. To enter Fastboot mode, hold the “Power” and “Volume Down” buttons simultaneously for 5-10 seconds. Release the buttons when the Fastboot screen appears.

  4. Connect your phone to your computer and click “Refresh” in XiaoMiFlash to scan for the device. If a device is detected, you’re good to go.

  5. Make sure to select “clean all” (this is very important). Failing to do so may result in your phone having a locked bootloader after the flash is completed.

  6. Click “Flash” and wait until it shows either a success message or an error.

For different ROM types:

  • ZIP: Flash the ZIP ROM using the “Update” function in the System or via TWRP.
  • EU: Flash the EU ROM using TWRP.
How to unlock bootloader Redmi K90 Pro Max / POCO F8 Ultra

Unlocking the bootloader of your device increases its vulnerability to malware attacks, potentially exposing your private data. Some high-security features, such as “Find device” and added-value services, may become unavailable. Additionally, unlocking the bootloader may result in the loss of phone data, including photos, contacts, SMS, and application data. Proceed at your own risk.

  1. Log in to your Xiaomi phone with your Mi account. Navigate to “Settings” > “Phone information” and tap on the “MIUI version” seven times. This will enable developer options.

  2. Go to “Settings” > “Additional settings” > “Developer options” and select “Mi Unlock status.” Press “Add account” and wait for the success notice. (Please note that this step requires a SIM card and mobile data to be enabled.)

  3. Download the Mi Unlock app to your PC and sign in with the Mi account that you’ve used on your Mi phone.

  4. Manually shut down your phone. Then, hold the Power and Volume Down buttons simultaneously to enter Fastboot mode.

  5. Connect your phone to the PC using a USB cable and click on the “Unlock” button within the Mi Unlock app.
