I recently installed lakka on a old flash drive and made some testings and I noticed that the system boot directly to the install menu. And I need to press TAB and type “live” to run in live mode, is there a way to boot directly in live mode without typing anything?
My english is very bad, sorry. 
By default, Lakka boots directly to live mode. You need to type installer to install it.
I think I tested the installer first and now it only boots to the install menu…
Any way to reverse this or I need to reflash my USB stick?
Thanks!
You need to reflash it.
Don’t need to reflash. I got stuck in live mode and figured out I could force installer mode by modifying both copies of “syslinux.cfg” in the thumb drive using a text editor. Change the default from “installer” to “live” and that should do it.
