I patched my Archos 5 (Gen 6) about 9 years ago using the instructions here:https://sites.google.com/site/archos5imt/patched-fw
I then upgraded the HDD to a 750GB drive and it worked great for 9 years. I then sold the unit a couple of weeks ago, having first connected it to a PC and deleted all my media from it. The buyer at first reported that the Archos was only showing 150GB free space, and that when he tried to look for what was filling the HDD "all the files come up empty" (there should have been >700GB free).
He is now (a week later) reporting that it is bootlooping, and that when he hit the reset button he got a G6H Recovery (109) screen, giving options to recover/format/etc. He then sent a screenshot saying "Archos G6H Recovery (code 109) HDD Recovery Failed (code 2).
Any idea how this could happen to a previously healthy unit, and how to recover it?
