@andreasole I do not really think that product code matters. All you need is to grab the last version of 001 variant (because of that table) — the file will be named DFL61_HARMATTAN_40.2012.21-3_PR_LEGACY_001-OEM1-958_ARM.bin — and flasher for Windows (which I think won't run on Win10, so try virtual machine or liveUSB with Win 7 or Debian). In addition to the links kindly provided by aspergerguy I would like to add my mirror (there are some troubles with the site certificate now, trying to solve them ASAP).
