Tianyu E688 is not turned on. What is the reason?

1) You can enter the recovery mode first, and then double-clear, so you can generally troubleshoot.

2) How to enter the recovery: press and hold the volume increase button+power on button, and then let go when the screen is red. Use the volume key to select and erase the first two lines of English. Please press and hold the power button to confirm, and then select the first item to restart the phone. It should be no problem.

3) If it doesn't work, it's a font problem. I suggest you contact Tianyu after-sales service center at /internet/index/shop_type/2.

I hope the above reply is helpful to you, and thank you for your support of Tianyu products ~
