I bought two faulty devices, I suppose in the same place where you found them.
I reported about it here:

If you buy, do not take any recovery steps, you can make it even worse. Immediately remove the SD card and clone it.
Later I got my hands on two more devices, which were a little more difficult to recover, I mean the image from the faulty SD card, but it worked out too.
If you still need an image, write to me in PM.
