this problem is HW and not SW.check exrernal connector matrix if it is broken or have water damage

the phone thinks that its a portable handsfree connected to the system connector. probably its the esb/usb filter that need to be changed it handles the systemconnector or the the system connector is water damaged. if this doesnt help its vincenne. if you have a pic of the board i can show you where the components are placed.

For sure is ESD protection filter/resister matrix - in 99% fault is after water damage

99% damaged if you before flashing changed by mistake + and GND.. and
after the phone was not booting you changed the polarity...

this the right reply

it worked ok if the cable was pluged
i fix it by lowering down the voltage when cable is connected...
