Boot screen is a lot of parameters (Recovery mode)

The device system may have crashed for some unknown reason, please try the following:

1. Select “Wipe data/factory reset”, then press the power button to enter the clear data, and then restart as prompted.

2. Long press the power button on the phone for 10 seconds to recover the software; if it is a tablet, it can be recovered through the reset button (the location of the reset button is usually next to the power button or the same location on the side bezel in a small hole), and then poke it with a pin to remove the card.

3. Download the system firmware and brush tool, through the computer wired connection for firmware upgrade, generally can be solved.

4. If the above steps can not be solved, you need to overhaul the hardware.
