Not working at all, pls help

I purchase a new BTT Pi 1.12.

I followed the instructions, burn the iso provided here to an SD, edit the config to give the SSID and password, insert SD at the BTT and.... Nothing happen, no connection.

I tried to even use a open wifi network, 3 diferent router, even I tried to share the wifi of my phone, nothing happen, the BBT not connect so I can acces it, I dont know even if it is working or not.

The green led is ON and still. I tried to power it using USB-C cable and also using a 12V PSU of my printer. Nothing.

I tried to use both images provided, the klipper one and the minimal, I tried ballenaetcher, rufus and the RPI imager... Nothing works

Also I tried the network cable connection however the leds of the ethernet port dont even turn on.

Help pls.

EDIT: After lot of issues, I works by using an old image from older version.... >.<

I want to update the system, how can I update the system? apt update is not working at all, the terminal simply frozen. Also at the mainsail web the CPU is almost all time at 80% or more... Is this normal? Im starting to regret the purchase of this cheap chinese RPI clone

EDIT 2: So as I can see the support is horrible. All is working now by using ratOS and uninstalling this crap oficial distro. This is the payback for cheap chinese clones of RPI...

Start with the provided Klipper and minimal images, the edited Wi-Fi configuration, and the reported Ethernet, apt, and CPU symptoms. Compare the current images with the older image that reportedly worked and review the ratOS edit; done would require a reproducible diagnosis or a documented compatibility status for the BTT Pi.
