Cannot Flash Fritz-Repeater 1200AX

Cannot flash Fritz Repeater 1200 ΑΧ.

eva_ramboot.py runs successfully but it never ask from tftp server the FRITZ1200.BIN

Tried both windows and ubuntu.
Fw is disabled.

Anyone has flashed it lately?

How can i pinpoint the issue?

my device is Fritz-Repeater 1200 AX. It is different from Fritz-Repeater 1200 with out AX?

Certainly a different device.
Some info here:

Different SoCs and stuff...

But supportable if @alexanderk is into further device exploration (without initially dismantling device case)
