Hi,

I've just updated my Z30 firmware:

[  5.792702]    <<<==== INTO SD CARD UPDATE CHECK MODE upgrade ====>>>
[  5.265204]    <<<==== INTO SD CARD UPDATE CHECK MODE upgrade ====>>>

[  5.395612]    Current reboot without Update.

Unfortunately I'm not able to operate camera using DJI GO app after upgrade.

How can I fix it? As far as I know downgrade is impossible. Perhaps any formatting camera memory? I'm stuck with this:

[  5.401285]    The current firmware does not support downgrade. Use a different version of firmware to downgrade the target version.

How can I downgrade the Z30 camera ? It's in conflict with the Matrice 100 and won't film or photograph.

Did you find a fix to this at all? Im having the same problem

HI,
Yes I have it fixed. I've received a patch directly from DJI Support. You can find it here:
