After searching for a firmware for my old Movie Cube R 500Gb (HW model: RTD 1261, older from 2007) and not found it on emtec website, I've seen that the updated firmware 2.0.9up for R100 model is compatible and it works like a charm. So, I've updated the Movie Cube.
After that, I've seen this web to do some useful "things" to this toy.
The first think that I've tried to do is to change the predefined desktop but without success. This are my steps:
1. telnet with PuTTy and root acces. This is ok. I've see the mounted partitions and folders.
2. access to /usr/local/bin/Resources and edit with vi "swconfig.ini" file
3. change with vi "sustom_id = 1" parameter to 2, 3 or 6 ("sustom_id = 6", for example)
4. exit Putty.
5. turn off movie cube.
After this "little" change, I can not do ANYTHING with movie cube. It gets hanged (turns on but no Guide menu nor other options; also the "blue LEDs" are always on). The only thing to recover it is re-installing again the firmware 2.0.9up (no Wired LAN access with telnet either).
Any suggestion of what I am doing wrong?
PD: Good work with so useful discussion!!!
