Sorry - I don't know about KK2 but in general PID tuning takes place in the before mentioned steps...

For tuning first you have to find optimum P gain and for that it is good to bring I gain to zero so that it can not interfere with P gain. Once you find the P gain you can find I gain. Less I gain will bring copter to the level automatically. If you increase I gain you will get your copter in heading hold position, which is good for learning. Keep the I gain same as P gain or 50% of P gain.

Once you find P gain you don't need to change it, just keep it as it is and find I gain.

Try flashing it with v1.5 or the newer v1.6. My quad flew good with the stock v1.5 settings. EDIT - In the RECEIVER TEST option, trim all the values to Zero before you fly.

1.What kind of 'issues' are you facing with flashing your KK2?
2.Have you trimmed all the 4 controls to zero in the RECEIVER TEST menu?
3.A video of your quad in action would probably help understand the actual problem...

"If it's man-made and it flies, it will crash."
aditya-

"And I can confirm that the ESCs and servos, even those connected to M2-M8, (cause they load the outputs of the KK2) must be removed when using a programmer that supplies power to the KK2! Else it is a chance of bricking the KK2 due to low voltage during flashing."

Got it veloci bhaiya, even though I sold my kk2. Sad

Its a good thing to do but, the flex is NOT the reason for the uncontrolled yaw that you experience in your quad.
