Since the system is recovered, we suggest you do some test to the USB OTG in Android system to see if the OTG is really broken.
You can plug a usb mouse/keyboard/harddisk to the otg port via an otg adapter.
1. If the mouse/keyboard/harddisk works, then otg function is considered good.
You can check the RECOVERY and RESET button.
2. If the devices do not work, check the voltage drop of the OTG DM to GND, and OTG DP to GND.
(Use the diode function check of the multimeter). Post the result here.
