I am using USB cable for VCC and GROUND, but VCCQ i soldered on the motherboard, but the live phone I soldered everything on the motherboard because with USB it slwas giving ERROR AT SEC 0

I wrote full dump from working phone, I wrote Boot1, Boot2, CSD from working phone , but no download mode coming when press Vol Up and Down with USB cable
