As you all know, just got my P4P back from the DJI repair with a camera problem and thanked everyone for this.
Made one flight with it a couple of days ago and today i powered on and asked to upgrade, so i did.
While updating, the camera went to the one side, start coming back very slowly and a sound (like its touching somewhere) will not stop and the picture / camera shakes unstop!
Tried and refreshed the update, restored factory defaults, did IMU and compass calibration fine but the gimbal calibration will not finish. It stays at 50%

I have 2 jobs in a row to perform this week so i urgently need assistance!!!
Please admins, any downgrade options or any way we can fix this ASAP as it must be a software problem!

Sorry for the trouble caused, please PM me your DJI account, we will try our best to help you out, thanks.

Thank you!

I did in the PM. ;)
"AUG 28th
Good morning from Cyprus!" and continued with other text.
Also did follow ups before i got any reply and answered the questions you have asked after.
Thank you for the reply!

UPDATE
After the update the camera was buzzing and shaking.
Refreshed the update, calibrated everything, restored factory defaults with no success.
Surprise was that i removed the battery and replaced it with another.
Did only the gimbal calibration and passed the 50% at last ... was corrected!
After this, i did again all calibrations with the same battery and all went fine.
I have also performed 4 full battery flights with no problems ... apart from one almost fly away with all 4 lights going RED but saved it!!!
Hope this helps someone.

Just another issue now. Powered on the P4P, initialized and then the camera just hanged dead.
Needed to restart to make it work.
Then the gimbal was buzzing and had to perform on the spot a gimbal calibration.
Any way i could have the old firmware to downgrade or other newer (even beta) that eliminates these problems as the old FW did not have any issues?
You have my email in the PM, Thanks!
