Deco X55 Firmware Upgrade Stuck on Dowmloading at 50%

Model: Deco X55  
Hardware Version: V1
Firmware Version: 1.2.0 and 1.2.3

I purchased the Deco X55 (1.2) three-pack a while ago and it has worked fine. I just purchased another X55 (1.30) to extend my range. While browsing to the main Deco, it alerts me that a firmware upgrade is available. The three-pack is currently at 1.2.0 Build 20231229 (upgrade suggested to 1.4.6 Build 20250211). The new unit is at 1.2.3 Build 20231027 (upgrade suggested to 1.2.10 Build 20241105).

 

When I select upgrade, a screen opens and says it's downloading, but it remains stuck at 50% as shown in the pic. This time it's been sitting there for 20 minutes.

When I access the main Deco with the app on my iPad or iPhone, I am notified that "New firmware is available" but it doesn't provide any detail as to hardware or version. When I select "Upgrade Now", it does the same thing as in the browser - it gets stuck at downloading 50% but the app quits after a while. If I check for new firmware files on the TP-Link website (US), hardware and firmware versions are not even close to the versions shown in the attached pic. This is very frustrating. Can you help?

Also see if the steps here help 

 

https://www.tp-link.com/us/support/faq/2301/ - Also try to update via Ethernet vs WiFi. If you already tried ethernet then try to update everything via WiFI

  @DenPik  Can you check the HW version numbers on the bottom of the units themselves, and/or the box(es).  Then try to manually upload the firmwares towards the top...

 

When I log into the Web GUI I see 1.0 but the actual version is 1.6...

Here is a link to the firmware for the X55 1.2

 

https://static.tp-link.com/upload/firmware/2025/202502/20250225/Deco%20X55%201.2_1.4.6%20Build%2020250211%20Rel.%2039448.zip

 

I can't for the life of me find the firmware for the x55 1.3 - Can you please confirm it's an X55 and not another model? Look at the bottom of the unit and snap a screenshot and msg it to me

  @DenPik My thought is you remove/uninstall the 1.30 version from your mesh, try to update the 3, which seem to have not been updated in a long time, if ever, use the replace main DECO function (in the app) and swap in the new one to the one connected to the modem/ONT, put that old one in the "Main Bedroom".  Then try to update again.

All, The problem has been solved. I took the new unit offline and upgraded the firmware that HelpFixDecoApp provided. Then I brought the new unit back online and checked for firmware. When I selected the Upgrade button, it downloaded very quickly and installed. Apparently, having two different hardware versions at the same time I tried to upgrade caused the problem. Thanks for all your help! I couldn't have succeeded without you!

The question now is where is the firmware it's not on https://www.tp-link.com/us/support/download/deco-x55/ unless I'm reading it wrong. I sent Carl a msg he works for Tp link he should be able to track it down for you
