There are a couple of methods to easily unbrick or restore your Redmi Note 9 handset. You can perform any one of these. Just head over to this in-depth guide on how to flash stock firmware on a Xiaomi Redmi device.
However, if you’re facing issues with the misc.bin partition or black screen issue such as if you’ve flashed the misc.bin partition by using an outdated TWRP recovery on your handset then you may encounter a black screen (bricked/bootloop) status. In such a scenario, there are two ways to fix the bricked or bootloop status on your Redmi Note 9 device easily.
Method 1:
Note: If you execute this command wrong, you will ERASE any other partition and it can brick your device forever and cause more damages.
- Once your device is on the black screen, plug it on USB (try USB3.0 first) with the computer.
- Make sure that the connected device is detected in the ADB Recovery mode.
- Now, open Command Prompt inside the Platform Tools folder and run the following command: [If not, make sure to reinstall the USB driver and properly follow the Platform Tools method]
adb devices
- Once your device appears in the ADB Recovery Mode, you’ll have to erase the misc partition by running the following command:
dd if=/dev/zero of=/dev/block/mmcblk0p2
- Once done, you can reboot your device to the system or fastboot again according to your preference.
Method 2:
- Once your device is on the black screen, plug it on USB (try USB3.0 first) with the computer.
- Then check if it is detected in adb recovery mode by running the following command:
adb devices
- Next, you’ll have to reboot the device in the bootloader mode by running the command below:
adb reboot bootloader
- Once done, check if it is detected in fastboot mode or not by executing the following command:
fastboot devices
- So, if you can see your device is detected in the fastboot mode, then you’ll have to erase the misc partition by running the command below:
fastboot erase misc
Note: If you try to format the misc partition, you’ll get this error: Formatting is not supported for a file system with the type ‘raw data’.
- So, do not format the misc partition. Once done, you can reboot your device to the system or fastboot again according to your preference.
- You’re done.
Conclusion
