Model: Deco M9 Plus  
Hardware Version: V2
Firmware Version: 1.5.1 Build 20210520 Rel. 40426

So a few weeks ago I downloaded a firmware for my Deco M9 Plus V2:

 

M9Plus_2.0_en_1.5.5 Build 20210519 Rel. 35582_US_JP_EU_up.bin

 

I manually downloaded it because checking for updates in the Deco app didn't show this one but it was on the website.

 

Now I look today and I don't see this firmware available anymore.  Did this get pulled?  Is there a problem with it?

@autigers1970 

Hi,

This firmware was published on the official website by accident and now it has been withdrawn.

There is no issue with this firmware and please don’t worry about it.

@TP-Link if there is no issue, why was it withdrawn?

 

I've got three M9+ running on 1.5.5 and I would like to know why this firmware was pulled. Should I downgrade back to 1.5.1?

@ShadowVlican 

Hi, Sometimes, the local websites did not update the latest firmware in time, and uses tend to go to support.com/en or support.com/us to check what is the latest firmware. Some users would confuse whether they should update to 1.5.5 manually via web UI since APP did not detect this firmware. Comparing with 1.5.1, 1.5.5 did not add any new features and it is not supposed to be uploaded to the official websites, only for cloud servers.

 

If you already updated to 1.5.5 and the Deco is working without any issue, there is no need to downgrade back to 1.5.1 firmware and later if there is a new firmware, both 1.5.1 and 1.5.5 would be able to receive the firmware notification on the Deco APP.

@TP-Link How can I downgrade to 1.5.1? My connection cuts out frequently after the upgrade.

I assume that I can upload the firmware using the utility and then will be ok.

Hi, yes.

Since 1.5.5 and 1.5.1 are both based on the same platform 1.5.x and they could downgrade or upgrade to each other.

Here are more instructions about firmware upgrade:
