I have a broken display which belongs to my friend. The mobile can power on but the display is still blank. I need to enable USB debugging to recover the data. While doing so there are these following .


  1. USB debugging is not enabled
  2. Bootloader is locked
  3. Mobile has a password (pin or character password)
  4. Devevoper options may not be turned on (cant tell now)
  5. Devices is not detected via ADB or Fastboot
  6. Cant go into the recovery or Fastboot mode
  7. Device is not rooted
  8. Custom Recovery not installed
  9. No SD Card slot

Terminal Output:

➜  ~ git:(master) ✗ adb devices
List of devices attached

➜  ~ git:(master) ✗ fastboot devices
➜  ~ git:(master) ✗ 

What I have tried?

  1. Tried Odin and SP Flash tool (Mobile not detected)
  2. Tried to enter the recovery and fastboot (No use)
  3. Tried ADB in a variety of OS (Win 10, Manjaro, Backbox, Win 7)

So is there any way to enable USB debugging in that device? Or any way of recovering the data. Any small lead that can make this device accessible via a computer is really helpful.

Note: How this differs from other similar questions:

Those devices that have this similar problem atleast have USB debugging enabled in the first place. Some can still go to recovery where as I cant. Some have SD card support this phone lacks it.

  • Don't go down that path. Find a custom recovery (both Philz Touch and TWRP exists for this device) and flash it using SP Flash Tool. You don't need an unlocked bootloader or USB debugging enabled for that. You need that software and a scatter based ROM for your device. Load the scatter file and flash only the recovery partition with custom recovery. You can Google how to use that software. USB debugging is by-default enabled in a custom recovery. – Firelord Aug 25 '18 at 10:06
  • So @Firelord you are saying SP Flash tool does not require USB debugging to be enabled ? – Vimal Joe Aug 25 '18 at 10:08

I would suggest: Connect keyboard via usb otg and enter password (buy usb otg if you don't have it). Disconnect keyboard and connect PC, take a screenshot on your phone and load it in the PC. Swap between mouse and PC (mouse to move around some, PC to step by step check how to get there by the screenshots)

  • The display doesn't work, so I am not sure how any of this is possible. – bobbyalex Oct 29 '18 at 21:25
