I recently acquired a GRX1200+ GNSS on eBay. The device is behaving like it's stuck in a boot loop, it intermittently responds to ping on ethernet, but rejects connections to any of the ports the documentation suggests it should always be listening on (ftp, http). Since I can't access the web interface I don't have any way to initiate a firmware upgrade.

The plot thickens a bit when I look at the contents of the CF: There's a "geto.php" file in the root, that suggests it's from some hacking group. (screenshot: <a href=" removed link " target="_blank" rel="noopener"> removed link )

I read a post in this forum from quite some time ago that there was a recovery procedure that could be used, does anyone have a copy they could provide?
