Hi and good evening.

I have a problem with my UNO R3 bootloader.

1. I don't know which .hex file to upload using ISP programmer.

2. I am using PICKit2 as my AVR programmer, based on wiring and instruction from http://technostuff.blogspot.my/2014/10/using-pickit2-programmer-to-program.html.

3. First try, I use "ATmegaBOOT_168_atmega328.hex" from "C:\Program Files\Arduino\hardware\arduino\avr\bootloaders\atmega". Result:-

Code: [Select]
C:\WinAVR\bin>avrdude -c pickit2 -p m328p -v -V -U boot:w:"ATmegaBOOT_168_atmega
328.hex":a

5. This means that the bootloader upload failed. Any idea, comment, suggestion on this issue?
Thanks.

Both bootloaders are  good for ATmega328P. The optiboot is better to use in my opinion. You are using 'boot' param for memory type but this is for ATxmega devices only. Parameter should be 'flash' instead. Don't forget to burn fuses also because they define boot vector and boot region, external crystal etc. Here is fuse setting for UNO:
uno.bootloader.low_fuses=0xff
uno.bootloader.high_fuses=0xde
uno.bootloader.extended_fuses=0x05
Hope it helps.

EDIT:
Try this
avrdude -c pickit2 -p m328p -v -V -U flash:w:optiboot_atmega328.hex:i -Ulock:w:0x0F:m

1. I'm using this command "avrdude -c pickit2 -p m328p -v -V -U flash:w:optiboot_atmega328.hex:a" without "-U lock...".
2. Is the "-U lock" is important?
3. Some info I got from "boards.txt" from "C:\Program Files\Arduino\hardware\arduino\avr".
Code: [Select]
uno.upload.tool=avrdude
uno.upload.protocol=arduino
uno.upload.maximum_size=32256
uno.upload.maximum_data_size=2048
uno.upload.speed=115200

uno.bootloader.tool=avrdude
uno.bootloader.low_fuses=0xFF
uno.bootloader.high_fuses=0xDE
uno.bootloader.extended_fuses=0x05
uno.bootloader.unlock_bits=0x3F
uno.bootloader.lock_bits=0x0F
uno.bootloader.file=optiboot/optiboot_atmega328.hex

uno.build.mcu=atmega328p
uno.build.f_cpu=16000000L
uno.build.board=AVR_UNO
uno.build.core=arduino


4. From info above, do I need to set "-U lock:w:0x3F:m" first, then upload the code, then "-U lock:w:0x0F:m"?
5. I first using command "avrdude -c pickit2 -p m328p -v" to gather information from on-board m328p.

My UNO fuses it: (L=FF, H=DE, E=FD).
Arduino UNO defaul: (L=FF, H=DE, E=05).

Will this make any difference/performance/error/problem/issue with my UNO R3? Is so, what will you recommend me to do?

Lock 0x0F disables read and write from boot region, 0x3F enables RW. ATmega has all flash usable for program. Fuses define whether the end of flash have to be used for bootloader so this is a protection for the boot region - lock bit 4,5.
Extended fuse - only first 3 bits have meaning for 328P (0-7), the rest is unused. Extended fuse byte defines brown out detection level 2.7V for 0x05. 0xFD is the same. All is described in the datasheet, chapter 28.
It is good to gather information from MCU first. It can save unnecessary writes to flash and so wearing.
I think this is all you need for now, just note only to be sure that your setting is for external clock source so the crystal or other kind of clock must be used otherwise MCU will not start. Try it and post the result for a feedback.

Code: [Select]
avrdude  -c pickit2 -p m328p -e -u -U lock:w:0x3f:m -U efuse:w:0x05:m -U hfuse:w:0xDE:m -U lfuse:w:0xFF:m -U flash:w:optiboot_atmega328.hex -U lock:w:0x2f:m


2f vs 0f for the final lock bit value is a personal preference.  2f allows the sketch to read the bootloader area (and report the optiboot version, for example.)  0f is the current arduino default.
