Want to update my DECO M5
I'm using my DECO M5 for several years.
In 2019, I had a big trouble, such as unstable connectivity, no internet after updating firmware into 1.2.5.
At that time, I received engineering firmware form tplink support team, and I solved my connection problem finally.
From last manual update(using GDPR.exe) into engineering firmware, my decos are still working perfectly now. But, recently I found a problem that my deco is not able to update anymore from 1.2.8.
In my android deco application, it said that all things are currently up to date. so I can't update my deco by myself.
And, Because there is no web interface in 1.2.8 firmware as you know, I can't access the update dialog box in web interface.
Could you tell me how can I update my deco firmware into most recent one?
