Finally got a new p4p after a warranty claim. Took 21 days from warranty claim to having this one back. Thought everything was great...So about an hour ago I opened the sealed box. Took all stickers and packing off ESPECIALLY the gimbal clamp AND gimbal packing block. Had a fully charged battery put it in - started up. Noticed a small screech sound when gimbal moved - not heard before. Connected RC and phone, did FW update to 0602 without issues. Performed an IMU and compass - all good, apart from RC which I believe needed updating too? But that was not the big concern - I tried a Gimbal calibration and this! Is this fixable or am I now to wait another month until I try another box?!?!

Still no solution Cannot downgrade the firmware on mobile or assistant 2 (as in one suggestion)...

I'm so sorry for the unpleasant experience, would you please PM me your DJI account? And keep me posted on thread once you send.

Hi Mindy  just sent PM

Attempting update 01.04.0608 (which has just appeared literally in the last few minutes) to see if that has any effect... ?

Well - that update seems to have improved things - still testing...

OK, keep me posted if there is further problem.

Just checked my Care Refresh  for the previous p4p and it seems inactive - won't accept serial or agreement number - given the new one was on warranty how to I now reactivate with the new serial and gimbal... assuming some more checks I do tomorrow are all good?

I've checked the status that the DJI Care Refresh is still associated with the old drone, please send email to  djicare@dji.com with the old and new serial number and the case number as well, they will assist.

Have done. Many thanks
