Hi all!
I'm having a problem here - my N900 won't boot, and this is not even the main issue
First, I just noticed that for some reason my device was in 'flight-mode', and when I tried to put it back on its normal mode, it began to behave weird so I decided to reboot it.
Since then, it won't boot anymore - when pressing the power key it vibrates but gets as far as the "Nokia" screen, then it stalls for ~30 secs, and then the display dims off slowly until its completely turned off.

Long before this odd thing occurred, I installed BackupMenu V2 and backed up my entire system successfully - but even if I try to power the device with the keyboard open, BackupMenu won't start.

Now, is it possible to access the device's file system in flashing mode? I can get there and I already reflashed my firmware but the device would still not boot (not eMMC yet). I also tried activating R&D mode, but the device is still acting the same way as before (going as far as the "Nokia" screen and then slowly dims off), only of course while having the R&D icon below the 'Nokia' logo...

I don't know if it has anything to do with it, but my device was overclocked (930Mhz + 500 dsp) for quite a long time before today...

Any help - as usual - is highly appreciated
