Don't quickly, take that decision, there is so many problems with latest KK firmwares,
I was recently trying my luck with 2 KK5.5 flight control boards , Each time I upload the same firmware, the response is not same, me too even thought the board is damaged, but identified it is firmware problem, After uploading same firmware many times, Now I am searching for older version firmware.

I think KK LCD boards have no seperate 3 axis gyros, There is SMD gyro+acc on it.

Is your stock f/w really for X mode?
Which is your stock f/w ?
(don't know if you already answered this questions.)

How much do you lower your throttle while landing.
Is this first time flying a quad ?

No, not first time.Flew many mini and micro quads.Also practised in simulator.I go very gentle on throttle.I feel that the quad reacts late to my input.Pi values are quite good and low.At certain altitude while landing, It makes more noise and comes down quickly.

Just try with default PI values by resetting the board.
And then tune PI again.
do you have expo or throttle curve set in Tx ?
