If the OF starts when you plug USB (without holding select), you're running 3.6, not the current build.

3.6 is the last release, "current build" is what you get on the left of the website, which is the source code built after each source code change (and there are several changes daily)

rekkataichou:
I see now, thanks!

You're right. This does fix the recording issues (and gives the RB Sansa a Multimedia mode). That just leaves the clock and the radio... which might be a hardware issue since these problems are both carried over to the OF.

That leaking pen battery (I'll need to find a replacement) I saw when I opened mine up might be the cause of a resetting clock (as the OF does) -- though I wouldn't know why RB would have a stuck clock.

Just supposing: the RTC might always return the same date, but the OF might fake the time with its periodical counter instead of reading the RTC each second/minute.

Sorry funman, but you'll have to break that down for me.

If the Sansa's real-time clock is dead/stuck, wouldn't the OF clock keep its "fake time" consistent? When I adjusted the "fake time", why would the OF clock suddenly flash back to a much earlier year and date?

[*]For example, the "fake time" in the OF starts at 2007/9/24 12:00.
[*]I wait until 12:03 to change the date/time to 2010/09/07 8:00. I apply the changes.
[*]The OF "fake time" now reads 1970/1/1 12:00.
[*]I wait until 12:03 to change update the time data again... when I apply the changes, the OF "fake time" resets to 1970/1/1 12:00
[*]Should the fake time at least update (until I power the system off)?[/list]
.
The RB RTC just holds steady at 2006/02/07 6:28:15... and doesn't budge a second. (I wonder if there's any significance to that time?)
Edit
Fiddling around with it some more, if I edit the OF clock, it too freezes (1/1/1970 0:00) without budging.

Also noticed that the OF radio would only tune in 0.2 increments instead of 0.1. Plus in the r27994-100903 build I have, entering the Radio freezes the screen, but as I said before, the wheel/buttons still cause the screen to fade in and if I had an application (such as Battery Bench or Music) running, it would still run in the background. The device would not connect in  Rockbox Media mode if I attached the data cable to it while it was frozen.

mc2739:
Have you tried doing a firmware upgrade with an unpatched Original Firmware since your recovery?  If not, it would be a good idea to try that.

It may also be a good idea to do a format before installing Rockbox again.
