Well, I had some problems recording the UNO bootloader on the first experiences, and got stuck with 2 chips "bricked", now that I have some spare time, got back to them and found a shield/guide of how auto-recording the chips, and how to recover them, the code is here and the way to connect the pins of the chip which you want to burn, are here:
The configuration is an arduino board and a breadboard with the chip which needs to be recorded/the "bricked" one. After connecting the pins to the second board (as described) you should upload the code to the arduino, select:"Tools-> Programmer->Arduino as ISP"
and "Tools->Board->Arduino Uno" proceed as in the picture:
It worked for me and I "unbricked" the chips, you can see the entire article here.
The standalone project is here, hope someday to have time and € to do one, for myself!
Update on the 12 February 2015: Gave up on standalone project, because it does not use the optiboot code and does not work very well, or not at all. I will build a shield to burn the UNO's using things explained within this article. Also updated the code link to a 2011 routine, instead of the 2009.
Update on the 13 February 2015: Gave up of the updated 2011 routine, didn't work for the ATmega328P-PN, back to the fine 2009.
This procedure will work on ATmega328P-PU and ATmega328P-PN, for the ATmega328-PU you will have to use the following workaround:
Workaround for ATmega328-PU:
In
your Arduino folder, find the subfolder: ..\hardware\tools\avr\etc
Make
a backup copy of the file: avrdude.conf
- Open the file avrdude.conf in a text editor
- Search for: 0x1e 0x95 0x0F (this is the ATmega328P signature)
- Replace it with: 0x1e 0x95 0x14 (this is the ATmega328 signature)
- Save the file
- Proceed as described previously
- Restore the avrdude.conf to it's original settings
