This thread worried me today... Here's the story:
I decided to add new recording. So, I go in the recoding menu, select the "Setup New Recording" menu, fill in the information, then select "Done". When I go in the "Already Scheduled" submenu, my new recoding does not appear. So, I think that I must have forgotten to select "Done". I repeat the add schedule process. No improvement. I then suspect that there's some file system corruption, or something. So, why not do a shutdown? It's been a while since I've done one... So, I shutdown.
Then, I restart my SL2. It starts booting: one circle filled, two, three, four... so far, so good... then... nothing! It waits on that fourth circle. After a few minutes, I shutdown (holding the off button for 12 seconds), and reboot. Same thing. It doesn't get past the fourth filled circle.
OK, time for a device recovery. Now, having read this thread, I get worried! :scared:
So, I launch the device recovery. Luckily, everything went OK. The recovery software didn't seem to download anything off the internet, though. This usually takes quite a long time. Instead, it stared sending the software directly to the SL2. (Probably, it had a copy stored on hard disk from the last recovery). Anyway, the SL2 got the software, rebooted itself, and now it's back working.
