Interesting as my TX7 runs 6.0.1 see pic.
Also i think Wifi chip may be different ??

Can you compare my findings to yours ??
Edit: Just saw this TX7 Android 7.1 Amlogic S905X Quad Core 2/32gb Dual Band WiFi 2.4GHz + 5GHz Bluetooth 4.0 -

Looks like the TX7 has Android 7.1 now.
I am pretty sure the Hardware is the same as mine or older stock.
No idea where the Firmware download is.
I asked Tanix for it 2 weeks ago with NO REPLY.
