Hey guys,
Okay. well when you have a bad you have a bad day. Sorry for the interrupted post above. Am used to press shift enter when jumping to next line...which in this forum apparently posts the post.
I am a bit down on my nerves. I have been trying to flash the bootloader on a Atmega328p running at 3.3V and 8 Mhz using an Arduino Mini with the same specs.
I used this video How to Burn Arduino bootloader using Arduino Pro Mini - YouTube as guideline.
I put the ArduinoISP on the Mini using an FTDI.
Pin 10 of the Mini is connected to RST of the Atmega328p
Pin 11 with MOSI
Pin 12 with MISO
Pin 13 with SCK
GND to GND
There is an 10uF ELKO between RST and GND of the Mini.
I then switch the IDE to Arduino as ISP and click Burn Bootloader.
And every single time it comes back with:
avrdude: Device signature = 0x000000
avrdude: Yikes! Invalid device signature.
I went through a ton of forum posts and tutorials but I can't seem to solve it.
Here is the complete screen print from avrdude on pressing burn bootloader:

Double check connections and try again, or use -F to override
this check.
avrdude done. Thank you.
Error while burning bootloader.
Help would be greatly appreciated. I am out of ideas.
