If your Arduino Uno microcontroller has been damaged or got "bricked upwardly" and you demand to get information technology working again quickly, you will need to replace the microcontroller chip (ATMEGA328P) and then load the bootloader program to the microcontroller. Although in that location are ways of restoring a "bricked upward" microcontroller, a quick ready to go your Arduino Uno board working is to replace the microcontroller and and then sort out the bricked up microcontroller at your leisure.
When a new blank microcontroller is inserted into an Arduino lath, it must have the Arduino bootloader programmed into it. This only has to be done once. The bootloader is a piece of software that allows sketches to be loaded to the Arduino via the USB or serial port from the Arduino IDE.
This video shows what needs to exist done to load or "burn down" the bootloader to the blank microcontroller in an Arduino Uno board. Atmel Studio half dozen and the AVRISP mkII USB developer is used to fire the bootloader. The residue of this tutorial covers the details.

Why Use Atmel Studio?
If yous take loaded Atmel Studio on your PC and you effort to burn the bootloader to the Arduino using the Arduino IDE, you will get an error message in the Arduino IDE because of a driver clash between Atmel Studio and the Arduino IDE drivers.
The Arduino IDE displays the error message:
Error while burning bootloader.
avrdude: usbdev_open(): did non observe whatever USB device "usb"
The best solution to this problem is to employ Atmel Studio to burn the bootloader, rather than removing Atmel Studio and its drivers.
Hardware Setup
Plug the AVRISP mkII USB connection into a spare USB port on the PC. Plug the AVRISP ribbon cablevision connector into the 3 by ii header on the Arduino board. Make sure that you connect it the right way effectually. Pin i is marked on the AVRISP connector and on the Arduino header.
Ability up the Arduino either from the PC via a USB cablevision or by an external ability supply.
Burning the Arduino Bootloader
The bootloader is included with the Arduino IDE software. In version 1.0.1 of the Arduino software, you lot will find the bootloader in the Arduino folder:
arduino-1.0.1\hardware\arduino\bootloaders\optiboot\
The bootloader in this folder that must be loaded to the Arduino Uno is optiboot_atmega328.hex
Steps to Burn the Bootloader
1. Connect the hardware as described above
2. Commencement Atmel Studio
iii. In Atmel Studio, click Tools → Device Programming
4. In the Device Programming dialog box, select AVRISP mkII in the Tool drop-down box, ATmega328P in the Device drop-down box and Internet access provider in the Interface driblet-down box
v. Click the Apply button
6. Yous can click the Read push button under Device signature to make sure that you tin can connect to the ATMEGA328P microcontroller
7. Click Memories in the left pane of the dialog box
8. Browse to the bootloader hex file using the ... button then select the hex file
nine. Click the Program button
10. After programming has finished, click Fuses in the left pane
eleven. Change the fuse values to:
EXTENDED: 0x05
High: 0xDE
Low: 0xFF
12. Click the Program button
13. Yous can at present close Atmel Studio
14. Start the Arduino IDE and load a sketch to examination that the bootloader is working, e.one thousand. load the Blink sketch to wink the on-lath LED
