sh: cannot create /sys/class/backlight/acx565akm/brightness: Permission denied
Root shell enabled

I see the link, get the file "disable_ts.desktop". The code is " Exec=/bin/busybox sh -c 'echo "sleep 15; echo 1 > /sys/devices/platform/omap2_mcspi.1/spi1.0/disable_ts" | sudo gainroot' "
so I try

Code:

/bin/busybox sh -c 'echo 0 > /sys/class/backlight/acx565akm/brightness | sudo gainroot'

But it was the same.
In fact, I just run my app.py using by cmd shortcuts launching. But it will modify /sys file so that be permission deny. If it's running in terminal is good by root privilege.
