Marlin FW update failing

Hi I spent all day trying different solutions and have decided to ask for help. I do have experience of firmware updates and chip programming from years ago so not completely dumb and noob but I dont have much time to try all avenues.

I have an A8 and the firmware wouldnt update via usb (no bootloader) so I ordered a gangsta nano 3 off ebay (Atmega328) to follow this tutorial... This Tutorial......

I wired it all up a which I believe is correct as its identified and I have been able to write the ISP to the nano. albeit with a 10uf capacitor connecting RST and GND. I have managed to get as far as wrecking my bootlader completely and my board is now bricked, I am now stuck at running the Marlin sketch, it wont run it I will include the screen log.

I would appreciate knowing if its worth sticking with the nano or whether I should get a usbasp as I think its cos my nano is an aftermarket one? I have tried a few variable like with/without capacitor, different baud speeds ( as I was getting sync errors, I have tried pressing reset button at different timings, and I have used the (old bootlader) option to varying success too, I must have got through at some point as I have bricked the board,

please can someone shed some light thanks

         Double check chip, or use -F to override this check.

avrdude done.  Thank you.

is it worth using -f to override? if so where do I put it?

Can you post a diagram showing all your connections?

This is what I am using..

what you have pasted shows you are trying to upload marlin to the nano!

Once the bootloader is installed you need to change your upload method back to default (Tools>Programmer>AVRISP mkll back to default) and change the com port to the com port of your controller not the nano com port.

The changing of the com port is missing from the page you are following..

This is why the Device signature sees a m328p, its is seeing the nano
