I am a beginner in dead boot repairing software work. Recently a China keypad mobile (coolsand) was dead by wrong rom flashing. Now PC is not recognising that phone since it is dead boot. This mobile has RX, TX, VCC, GND, printed points on motherboard. Can I connect it with my easyjtag plus & repair the dead boot phone by flashing it original backup rom which in .bin format. My main concern is where is RX, TX points in my easyjtag plus box. Is it ethernet port present in the front side of the box?
