I got boot up error twice with ver 1.1.7.
i just turn on IQ tester but freeze during boot up.
if its happen, i need wait Battery will die. this is meaning i cant use IQ tester around 6-7 hours when i need to use.
See attached pic for freeze screen.
Thank you,

A fix for this problem will be added in the next firmware release.

Until then-
If this happens again, hold down [LEFT] and [RIGHT] buttons until the screen turns black or the startup screen appears again.
Holding down [LEFT] + [RIGHT] should restart the IQTester after 10-15 seconds.
