So, to update this issue for others. It turns out the controller firmware did not recognize that the EAP-225 was a "CANADIAN" ie US [CUSTOM] version. It's now upgraded to v5.0.8 firmware CANADA.

Thanks to the tp-link support personal for their help in sorting this out in a timely manner. However, I find it interesting that it did with the EAP620 HD(US) v2.0 [CUSTOM] "CANADA" that I have on the same network.

Hi  @tradenet 

The current firmware is a little bit outdated with Omada Controller V6, so please try to upload the firmware file manually to 5.2.2 firstly, and then to 5.2.3 (the latest firmware) with this link: https://support.omadanetworks.com/product/eap225/v3/?resourceType=download

You may refer to this firmware update guide:

Well, I've tried everything. From resetting to putting in stand alone.It just won't take the firmware. I've tried even loading earlier versions. In standalone mode it just comes back with bad file error. So I am at a loss as to what to do with it.

Hi  @tradenet 

May I check if you have any screenshot of this error when you uploaded the firmware suggested?

By the way, may I ask how did you update the EAP? Was there any power outage during the process?

Hi  @Hank21 

These have been the first attempts of trying to update the firmware since the AP has been put into service. Mainly because the previous controller Omada OC200 firmware had been upgraded to v 6. and the AP was flagged "outdated",  under the previous controller v. 5 firmware the AP had never been flagged for upgrades.

To answer your question, no there was no power outages during the upgrade process.

 

1.) My first attempt was to try to upgrade it through the controller UI. (image 2). I get a popup "Failed to upgrade no device ready to upgrade".

 

2.) My second attempt was to upgrade via custom upgrade ie. uploading the firmware. (images 3 & 4).  See error failure.

 

3. ) My third attempt was to disable mesh and wire it direct to the switch. However, the same issues persisted as above.

 

4. ) My fourth attempt was to move the AP off the network, forget it. Directly access it, however when trying to do the upgrade directly from it's UI, all I got was a "bad file" error.

 

I've tried different browsers, including "Icognito", reseting it and different PC's. Same issues.

 

I've put the AP back into service. No problems with adopting and provisioning including uplinking and mesh networking it. All working as intended using the orginal factory installed firmware.

 

So, now I am at a loss. I've tried everything.

Hi  @tradenet 

 

Thanks for the info.

That error message indicates you were trying to upload the wrong firmware for the EAP.

To better understand the situation, please share a screenshot of the EAP225's firmware page. We need to know the full firmware number.
