Upon dabbling ALOT with the LGMS550 (Stylo 2 Plus) MetroPcs) I figured out how to enable FULL OTG SUPPORT..if u try to plug in ANY usb device ...NOTHING HAPPENS...
Things you'll need..
1) ROOT...TWRP FOR OUR DEVICE...GOOGLE IT...DO THE WORK LIKE I DID
2) BUSYBOX,
3)ROOT BROWSER....THATS IT
USING ROOT BROWSER NAVIGATE TO- /sys/devices/soc/78db000.usb/power_supply/usb/usb_otg--edit from 0 to 1...save
NEXT go to/sys/devices/soc/78db000.usb/dpdm_pulldown_enable-- change from disabled to enabled
Next--/sys/devices/soc/78db000.usb/power_supply/usb/dp_dm change from 0 to 1..
THATS IT ...EXIT LLPLUG IN A USB DEVICE WITH OTG CABLE....A POP UP WILL SHOW IN UR DROP DOWN MENU...
PROFIT!!
I DID IT ...IM JUST A NORMAL SELF TAUGHT GUY..OH YEAH...ITS TRUE.TRY IT FOR YOUR SELF... it may take a couple times of plugging and unplugging your USB device but it will show in your drop down menu have a nice day
Oh yeah one more thing you're charging port will no longer work until you reboot when you enable usb OTG it becomes a USB host in your charging doesn't work anymore so you'll have to configure your own script at boot or whenever you feel like making it happen figure it out just know that you can't charge your phone until you reboot or change the values back bye bye
To disable so u can charge ur phone again..reverse all the values back..
Have fun
