I keep trying to change the old bootloader on my nano (update it) through the MEGA.
I have connected the pins :
mega - 50,51,52,53 -> Slave/Nano iCsp pins (did this and rechecked 5 times) As in photo.
I can Upload the ArduinoISP to the mega, no problem, but when I want to Burn Bootloader I can't.
"avrdude: Yikes! Invalid device signature.
Double check connections and try again, or use -F to override
this check."
Attatched the Log/verboise.
Please help! And thank you for your time 
I did try to check if there are people with the same issue, but I could not find it.
This has started from trying to flash something (Klipper from Raspberry) and noticed I get "not in sync"
The same thing I get when I try to upload anything on the NANO if I don't use old bootloader selected (in the tab) and try using just 328p.
Thus I thought I'd try updating the bootloader, maybe that will fix my problem.
No clue what to do.

Which sketch exactly. It can be pin 10 instead of 53 for reset. Check it in the source code, right at the beginning.
It was 10. THANK YOU! Honestly could not find it any documentation but it worked. I knew that since the pins were moved on the mega it shouldn't work. Yey. Thank you again.

It stopped working today...
Does this mean I burned it by mistake? The wires are the same but it's not working anymore... Any clue ?
You probably have some shortage on wires.
I realized I put the Nano on the CNC shield - the wrong way. Sigh. Maybe that fried it.
Either way, thank you. Tried another nano and everything works.
