Audible or Visual warning if the batttery is about to give out

[guu]

I think this error means your X is down, there is no gui in the gameshell now ,right?

so I recommend to re-flash the tf card of gameshell with os v0.4

that would be easier to fix the problem

@guu

you are on windows ,right ?

pull out the sd card from gameshell, then insert it into PC, but DON’T FORMAT IT , windows will notice you that
the card can not be recognize blah blah blah , just ignore,

the use

balenaEtcher - Flash OS images to SD cards & USB drives

to flash the downloaded img file into the sd card

windows will assign the sd-card a new Disk character , like D: or else, just check it in the My Computer and remember it
be careful

in etcher, select the downloaded img file as source, and select the new Disk character as target drive

NEVER choose the C: ,it’s you windows system disk.

then flash it

after finished, pull out the sdcard from PC ,re-insert it into GameShell, then boot up GameShell
All done.

the whole process is just a Restore factory settings

good luck
