Anet A8 Controller's Microprocessor Replacement

Problems:
When I tried to upgrade the Anet A8 printer, I forgot to turn off the power supply and make the main controller chip damaged.
Solved:
Replace the chip and re-flash it.

Steps:
1st:
Solder out the damaged chip and replace it. Take out your power supply, it will be used to power your controller board when re-flash the firmware.

2nd:
If you already have an AVR ISP programmer, so skip this step.
If you have an Arduino around, follow this link: http://make.kosakalab.com/make/
