Hi friends,

My KK2 board is on the way and I also have V3.0 flight controller board....

Will I be needing USB AVR programming device bootloader for the KK2 board..?

Thanks in advance...!

No you don't need it for the KK2 board.

Thank you Sir...!!   

Yes you don't need it except flashing new firmware. Stock firmware is v1.0

One more Q

Do we also need Atmel Atmega Socket Firmware Flashing Tool for flashing (along with the USBasp)

Sir that's for an ESC firmware(simonk or wiiesc) flashing.

thanks - i thought we needed some kind of 6 pin adapter. I forgot the hk usbasp already has it.
I just updated mine with V 1.2

Sir have you tried Scolton ACC mod fw? It's extremely stable and good for learning. I have uploaded the video in my topic. Yes 10-6 pin comes with USBASP sales package.

No buddy - haven't tried the ACC mod. I will definitely give it a try - thanks for the tip!

Just be careful with the unofficial firmwares.

Oh yeah sorry forgot to mention that, firmware is not officially released.
