Different firmware Deco M9 Plus
Hello. I am a little confused about the different firmwares related to Deco M9 Plus. In download area there is information about how to read the hardware version on the back. It says as an example that 1.x is hardware version 1. When it comes to hardware version 2 there different ones, 2, 2.8 and 2.2.
According to the stated example you could read this as 2.x and consequently all different firmwares of 2.0, 2,2 and 2.8 are possible updates even for hardware version 2.x.
Now in my case on the back side of my three M9:s it is written version 2.0.
So now my question: can I update my firmware to latest firmware Deco M9 Plus(EU)_V2.2_1.5.3_210309 that is listed under hardware version 2.2 or is latest firmware Deco M9 Plus(EU)_V2_1.5.1_210126 for me?
Anyone triednv.2_1.5.3_210309 on version 2.0?
thanks in advance
