Hello! In case somebody also is interessted: Medion did provide the UBOOT sources: http://cdn.medion.com/downloads/quellcode/Medion-Lifecloud-UBOOT_20101009.zip I didn't had time to really check the archive but from a first glance it looks prommissing.

Hello bodhi, good news is: I'm sill alive. Bad news is: at least until next weekend I won't have much time investigating. But I'm still eager to get this done!

Hello bodhi, > I think you should try with many different baudrates to see if any will work. How can the baurate be changed automatically at PC side? Stock uboot is at 115200 - this is needed to interrupt booting the stock kernel. When baudrate is switched by kernel - how can the PC change it at the same time? Another thought: can this older stock uboot load and run a newer uboby Peter2017 - Debian

Hello bodhi, > That's a nice script! how an experienced Linux user would go about doing this. Thanks for the flowers. But it isn't my knowledge - I just adapted it. It's originated here from this forum. I'll send you the (as far I can see relevant) output for double checking.

I also own such a NAS system (MEDION P89634 MD 86783, 2x2 TB NAS) as some of the users here have written of (helge and saschbear).
