i know its an old thread but maybe helps identifying.
I used arduino ide to flash the nano. First i got some of these sync errors (but a different number).
In the IDE there is an option for "ATMega328P (old bootloader)" this setting worked for me while "ATMega328P" failed to flash.
i guess chip is CH 340.
