As in title 
Everything was fine until a decided to update to 4.2.1.
Changing cables and sensors doesn’t work.
Any idea?
UPDATE 23.06.2022:
Switch back to 4.1.7 and… no issue.
Decided to compare parameters between them.
Only one that I could find are:
(4.2)
RELAY_PIN → -1
RELAY_PIN2 → -1
EK3_IMU_MASK → 7
NTF_BUZZ_PIN → -1
Q_A_ACCEL_P_MAX → 30000
Q_JERK_XY → 2
Q_P_VELXY_FF → 0,25
Cos I’m noob to all of this, can someone explain those differences.
As my noob knowledge tells me those first two can be the issue apart from IMU and BUZZ.
Happy flying to all…
