@daniel_at:
not by accident and not bv webfind :-). I just played around cause i read about the special mode on the m-series. I watch this thread for 1 or 2 month, so i think maybe i could do something useful ;-)
@mike16889:
interesting! I've tested it several times, on my player it works with or without the hold button. Maybe you haven't accidently not all the button all the time?

Very nice finding everyone. Daniel, I had a look at the ROM binary disassembly yesterday night and well, as funman said some of it looks very familiar with the OF but it is no surprise in my opinion. I don't know much about it yet, but a quick look at the contained strings, I can easily find the "M200Plus" string we saw when using the "recovery" mode... ;D

You can also make a homebrewn solder tip by wrapping around a ~2mm thick copper-wire around your existing solder tip and file it very pointed and use that for soldering. Sorry, hard to describe, i hope you understand what i mean, cant currently find a picture of it.

If you guys can get a hand on "flux", it _really_ ease soldering small parts and wire. It should be quite easy to get at a specialized electronics distributor and/or reseller. You just put a lot of it on the part to solder, use a standard to small soldering tip and stain will glue to the pads. Just as an example, I can solder very small packages (with <= 0.5mm pads pitch) with a >2mm tip (yes, the tip is really bigger than the pads)... ;) Just be sure to clean the PCB region afterward if the flux is not self-cleaning.

I seems to me this "reset firmware"-Mode does nothing :-(. If i hit the center, it, as reported before, simply switches off. I even can't see that switching on again takes any longer as normal.
So i tested around a little bit.
Only thing i discovered is, that if you plug in the e260 in this mode, a new usb device is found which can't be enumerated. Same can be archived if you connect first the device, then switch off and on again with the know button combination. Difference is, that no answer is displayed this way, only the logo.
Linux output of dmesg is:

still got the feeling this thing is no help anyway... :-)
mike16889:
i re tried and it douse work regardless of weather the hold is on or off.
@jesterday. did you have an updated (or custom) version of firmware running when you hit the center button? maybe it reloads the stock firmware?
tobi-lu:
I tried it on my e250, and it doesn't seem to work at all, regardless of the "hold" state. I have a custom firmware (compressed OF + 5sec delay). It always loads normally.
I'm pressing the back, forward and power button at the same time, is this correct?
edit: Aaah nevermind, it just worked, dunno why ???
edit2: OK, I just didn't hold the buttons long enough.
But there's nothing happening... no matter which button I press, the player just turns off and everything is like it was before.
