Hello.

What exactly You are trying to do? if You want to reflash the phone You can try to do this via Normal mode, follow Software instructions, make sure that drivers are installed correctly, try to use another USB cable.

You can try to do next: To enter emergency mode, disconnect cable, disconnect battery, press and hold "Vol+" button and connect USB cable.

yes im trying to frp , but no luck at all , i try all the steps even left the battery out for several minute before usb + power up volume .. is there anyway to internally add a resistance or a jumper so it goes automatically to download mode ?

Please, try to do next:

Please, put the phone into download mode manually (Power phone OFF, press and hold "Vol+" button and connect the cable (or P990 cable)).

Please, try to use another USB cable, (p999) connect phone to another USB port, currently no other solution to put this phone into Download mode, it's can be damaged partitions and phone can't enter into Download mode.
