Hi all. Same problem here with a brand new 3805e arrived with firmware 10.01.04.1003 trying to register to a V2110 with 09.21.09.0004 firmware. Although I tried to stop the downgrade via the "controlled upgrade", the AP keeps trying downgrade every time it joins.
I also tried to do a manual firmware upgrade as indicated here:

In any case. from controller or manually, the firmware downgrade always seems to complete without problems:
Jun 16 07:22:14 cap: Kernel image upgraded.
Jun 16 07:22:14 cap: Image upgrade done.

Jun 16 07:22:16 kernel: ap_drv: watchdog re-armed
Jun 16 07:22:16 kernel: ap_drv: watchdog re-armed
But upon reboot, it shows the same 10.01.04.1003 firmware. It seems like the logic on the image_upgrade scripts on that firmware version doesn't activate the new firmware downloaded. Also I don't understand why the "controlled upgrade" logic is not followed by the AP.
I opened yesterday a GTAC case, but it its not assigned yet,
Regards.
