Two X7 problems that look alarming and are not: a tiny boot menu instead of the normal start-up, and a forgotten lock-screen password.
If the power and volume-down buttons are held together for about 15 seconds, the X7 enters a factory boot menu. It shows three options, Emergency, Fast Boot and Normal, in very small text that is easy to miss on the screen.
To avoid it in future, do not hold Power and Volume Down at the same time.
Android does not offer a way to recover or bypass a lock-screen password, and neither can we. The only route is to reflash the X7 from a computer, which erases the tablet and reinstalls Android and iFly EFB. Your charts and settings restore from your iFly account once you sign back in. Contact support@iFlyEFB.com and we will send the flash package and instructions for your unit.
Factory reset without the password?
Not possible from the lock screen. The flash procedure is the reset.
