Well that was fun. Termux wouldn't load so I found an older version from 2022 thinking that version is older than the box so has a higher chance of working. That also wouldn't open until I went a bit silly and attempted to open it multiple times. Just like Mustafa in Austin Powers, once I attempted to load it 3 times in a row it would show up. Bizarre but I now have a dump of Device.DTB
How do I view it properly?
I opened it in notepad++ and most of it is gibberish but I can make out a few details that are a bit surprising. Namely - allwinner,h616 arm,sun50iw9p1
The label on this thing says H618 but it appears to be a H616.
Where do I go to from here?
Edit: I have attached the dtb file and two dumps of the file. One using fdtdump and the other using dtc. It seems the btlpm section has the same values of a device Nick referenced on page 4 of this thread. I don't know if that means anything....
Edit2: I tried "Armbian-unofficial_25.05.0-trunk_Transpeed-8k618-t_bookworm_edge_6.12.11_xfce_desktop.img" this boots ok, ethernet works but again, no wifi/bluetooth. I'm a little surprised every image I've tried so far has mostly worked. I guess these vendors just throw together whatever parts they can get cheap but the core of the units is the same.
Thanks.
