Premoderation on this forum is so long, that I almost forgot main purpose of my 1st message...
For owners of 0th & 1st models: if You want to have connection to PC via cifs (it is highly convinient thing), then You must perform following steps:
1. Create file t.oar on PC
dd if=/dev/mmcblk0 of=/media/flash/boot_dump.bin bs=512 seek=0 count=32768
The file must have UNIX format, i.e. lines must end with NL, but not with CR/NL as in Windows. Be careful because this command deals with bootload area.
2. Run this file on your e-reader.
3. Put the file boot_dump.bin somewhere on Internet, so I can take it.
Positive result is not warranted, but I will try...
