revive Medion oxnas stg-212 (15 replies)

Hey guys, as i didn't succeed on openwrt-forums for now and you really seem familiar to my device, maybe someone is able to help me reviving my Medion NAS? :-) For now i think my problem could be mtd-related and there is no place to uncompress Linux?

I tried to "factory reset" my Medion NAS running OpenWrt for oxnas by re-flashing openwrt-oxnas-stg212-squashfs-ubinized.bin. Device didn't come up again, so i checked with serial and got:

Starting kernel ...

Uncompressing Linux...

XZ-compressed data is corrupt

 -- System halted

After digging for 48 hours now i managed to update u-boot, but didn't manage to get any further booting at least into rescue or something else. Guess it's a pretty easy task for someone who knows what to do, but i'm simply failing starting kernel from 0x62000000 - at least that's what i'm thinking... My logs so far:

Any help much appreciated! I'm able to tftp via LAN and already managed to flash and rescue like 4 years ago after compiling my own openwrt for that device, but almost forgot everything in the last 4 years... :-/ THX i.a.!
