  • 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.
