@rafman Success! took a few tries to write the image - decompressing it first seemed to make etcher happier about it. (inside the archive the .img extension was missing)
lack of bt or wifi is no big deal as mainly looking to repurpose some of these into pi-holes.
Will let you know how I make out with the other box I have.
I have a mix of some boxes because was using some for remote android signage players for a customer, and the signage app did not perform well on some boxes.
Plus just other past tinkering.
edit: so just tested what was supposed to be an H313 (best I can tell from my buying history) - no dice. opened it up, it's an S905W. It was from primecables (branded) and board is a TX3MINI-P
If there is any other hardware that you spot or want tested, let me know. I don't mind buying & testing pre-built images. That much I have some time for. Zero programming chops here. Batch files at best.
