I have a micromax doodle 4 (Q391) with broken power and volume down buttons and its stuck in boot logo. So whenever I connect my phone to charger it will turn on and just keep showing the logo. However, I'm managed to enter recovery mode to reset device or wipe data BUT as I mentioned the power button is not working to select nor the volume button is working around to highlight options. Since its stuck in bootloop, I can't even enable usb debugging.
Btw, the battery can't be removed in this model. All I have is a reset button, volume up button and If i give some hard push on volume down its working sometimes. Some help would be very useful. Thank you.
