[SOLVED] How to write bootloader to Uno R3 with external programmer?

Development Tools IDE 1.x

Hi!
I'm new to Arduino world and this forum, but not new to uC and AVR.
I got from a friend an Arduino Uno R3 ( looks like an original ) board.
He would bin the board, and I told I would like to try to fix it.

So, the board is recognized by the Arduino 1.8.9 app.
It recognised as "Arduino/Genuino Uno"
That says to me does it is alive.

When I try to upload the Blink example, I got an error :

avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 9 of 10: not in sync: resp=0xd3

That's nice for now.
I checked if everything is configured as it should, and found no errors.
I also read many pages on the net and here and tried out two days many advices.
No progress.

I done the Loop Back test, which was passed.

I tried to read the ATMEGA328 uC with my MiniPro external programmer device, and the result was a good uC.

When I press the reset button on the board, the L light is somehow dimming until it reach the full shine.

I assume maybe a bootloader problem on the board.

So, my question is:
How can I ( if it is possible ) flash the uC with a new bootloader but with my external MiniProg programmer?

Any resource or a bootloader package I would appreciate pls.

Thank you very much.

So, here I am again.
I sorted out how to program the bootloader without any ISP device but with an external compatible programmer.
Here is the procedure:

  • fire up your external programmer
  • read out the FUSE bits setup and save it.
  • find the appropriated bootloader for your Arduino
    ( use the boards.txt from the Arduino installed directory to check which firmware u need for your board )
  • load the right firmware to the programming device
  • check if does the FUSE bits are correctly set
  • write the firmware to the uC

Job done.
Your Arduino should again be alive.
