Model: OC200  
Hardware Version: V1
Firmware Version: 1.37.11 Build 20251201 Rel.43290

Hi,

 

I've got an OC200 V1 here that I want to use as a controller for some older EAP245 V1.

 

The OC200 V1 currently has up-to-date firmware (Omada Controller V6.0), but the EAP245 V1 is apparently only supported up to Omada Controller V3.2.

 

After finding this "Downgrade" guide https://www.tp-link.com/en/support/faq/3684/ I downloaded firmware OC200(UN)_V1_1.2.3 Build 20200430 from the OC200 product webpage and tried to install it.

However, after I click the second "Upgrade" button I see the mouse cursor cycling for a while and then the message "Upgrade failed X" pops up.

 

Am I doing something wrong? What is the correct procedure for downgrading the OC200 V1 to Omada Controller V3.2?

 

I found older threads about downgrading the OC200 in this forum, but they didn't mention what to do if it fails.

Hi  @woozle 

 

Thanks for posting here.

It might be because the downgrade spans too many versions.

We recommend downgrading step by step—for example, downgrade in the following order:

latest version of V5  > the earliest version of V5  > the latest version of V4 > the earliest version of V4 > the earliest version of V3.

 

We will also test whether this is possible locally and will update here once there is a result.

Thanks for your reply.

 

I managed to downgrade in several steps to OC200(UN)_V1_1.15.2_20220323, but then I got stuck. The version right before that, which is OC200(UN)_V1_1.14.3_20220112, does not install.

Does it mean it is not possible to downgrade from OC200(UN)_V1_1.15.2_20220323 ?

 

If so, then why? I don't need to retain compatibility with any existing backup data. I want to setup the OC200 from scratch anyway.

Hi  @woozle 

 

Omada V3 has been around for quite some time, and OC200 units produced after a certain date cannot be downgraded to V3. I’m afraid yours cannot be downgraded either.

How many EAP245 V1 units do you need to manage? What specific features or configurations are you planning to use? If you don’t require advanced features, I recommend downloading the software controller for management.
