Battery Low [Q] My Glide charges only when turned off

yesterday my phone is fallen on ground and my display is now broken.
before i buy a new display, i wanted to check if everything else works..
and i see that my phone charges only when turned off.

i have latest cm10.2 installed and use the internal ssh server to check several things.

i see that voltage and capacity are falling.
cat /sys/class/power_supply/battery/batt_vol
cat /sys/class/power_supply/battery/capacity
it notice that it's plugged in and it know if its usb or ac
cat /sys/class/power_supply/usb/online
cat /sys/class/power_supply/ac/online
cat /sys/class/power_supply/battery/batt_charging_source
and it really don't charge
cat /sys/class/power_supply/max8922-charger/status
cat /sys/class/power_supply/max8907c-charger/status
cat /sys/class/power_supply/battery/status
All says "Not charging"..

i also noticed that usb otg works without problems but my computer don't find my phone when i plug in. i think by default it should be a mtp device or something? usually i never use usb connection..

has anybody an idea what could be wrong?
i think maybe my device is stuck in usb otg mode..
but what can i do?

Okay, since "reboot recovery" looks like it don't start anymore..
I will try tomorrow again..
Hmm, i tested on a other device. If i reboot to twrp recovery and do a hard reset, the phone starts twrp again until i boot system through twrp..
usb device still don't work, so i don't have adb and no option to leave twrp without a display..
