i have tried to flash the board back to KK2 factory firmware but when i connect it to USBASP the board wouldn't turn on at all,,,
is this a known issue ?
is there a solution?

PS same happend to the HK v3 board :-(
thanks

The only known issue I know for HCopter is that the LCD gets blank when u connect the battery, but u need to disconnect and reconnect the battery again... but this is not what u r saying here. also I faced no issue with the original firmware regarding LCD.

I am interested in the Sonar, in fact have ordered 5 for my Nazes and a couple for KK Boards, but, I am not sure if they can be used with KK2.1.5 boards.
The thread is so old that there is conflicting info right through it and changes that speak of upgrades that seem too old to be of any value.
I can't find any up to date material that suggests the KK2.1.5 can be used, nor any real list of Firmware suitable, let alone a wiring diagram.
There are plenty of outdated vids demonstrating that it can hover and little else.
I also saw mention that Lazyzeros flash tool can be used but there is no FW suitable in the listings there.
I am just getting confused by old information and may just stick to Naze as this research is getting me nowhere.
Pity because I like the KK boards too.

Hefnycopter till the moment does not support KK2.1.5 although there is a plan to do so with more feature than the old one, however this plan has been postponed for a while.

Thank you for your reply. At least I can continue on with Naze experimenting without wasting any more time.
I look forward to the future, but maybe there will be some major changes to the future KK board that may incorporate a few more features.
There has been a lot of demand to upgrade KK but it is possible it has reached its' limits.
