Thanks for your answers. @John1234 I 1st tried with Omada SDN Controller v4.2.11 with same failed. @Virgo I tried both local and cloud to upgrade without success.

Hi, Upgrade firmware by "Rolling update" returns failed : [Failed]Failed to upgrade EAP225_RdC to firmware version 5.0.0 Build 20200918 Rel. 58628 online. Same results when I try with "Manage Device"...
