Recovery mode is , witht eh player turned off. Turn teh hold switch on, then, while plugging in the USB cable, hold the Menu (power on) button until the player shows up as 16mb format.

I got curious today and decided to open up my v2. Unfortunately, I have no scanner and the only camera available was my mother's which has very poor macro-focus. My hands were shaky, but I did the best I could, taking multiple shots of everything that seemed worth noting. Anywhere text was printed, I took at least one picture. I also removed stickers from chip-sets so that the text could be read.
I'm uploading as 121mb rar file to rapidshare and rarhost at the moment. Connection is slow, I'll post links in about a half hour. Hopefully somebody else will be able to host them somewhere better, or at least whatever ones are most useful.
And yes, I know there are already images of one disassembled, I felt like doing this anyways.
EDIT: Rapidshare download part1 of 2 >>>

Alright, I hope some of you might find something useful in these.

The latest firmware update for the e200 v2's puts MSC mode back into the sansa's.

A recovery mode is pretty much the last thing we need before someone starts writing the first bootloader embryo to try on this target.
We have info to start that work, but if we manage to put a bootloader on this we need a way to revert back to the original firmware as the bootloader will most likely not work perfectly on the first attempt...

So, does anyone have any new ideas for us v2 owners to try to get into recovery mode? I think it's pretty clear by now that if the v2s have one, it's quite a bit different from that of the v1s. I've tried a lot of combinations of buttons while connecting the cable with hold on (and off, too, for that matter) on my recently bought e280v2 without noticing anything. Is it guaranteed that a recovery mode would make itself known immediately (eg by presenting a new partition)? Might it be necessary to check with fdisk -l on every new try, or maybe check for new hidden files on the standard partition?

First, it's quite possible that there is no user-accessible recovery mode.
Then, if there is one it could be triggered by any imaginary means and there's no saying it needs to be anywhere similar to that of the v1.

In fact, it could require the insertion of a hardware dongle attached to the accessory port, that the OF can detect, or some other means that is very, very, very unlikely to be stumbled upon.

Let's say we don't find how to turn the sansa in recovery mode, what could be tried to boot it with something else than the original firmware? Is their somewhere I could read about that? That way I wouldn't need to ask questions that sound stupid and I might help more
Edit: I tried stuff on my sansa an figured that if you press both center and power when it is open, then let go the center, the sansa closes but skips the animation. when i tried to turn it on, it blocked on the starting video. I then repressed power after like 30 seconds and it opened and read "refreshing database". I don't know what it gives us but I find it quite interesting since maybe at the point when nothing was happening, we could trigger recovery mode. I will get on trying combinations right now, but it is long since each time I need to go through each step
edit2: actually, i found that all is needed to do what i just said was to close using the center button and the power button. it takes about 10 seconds. you need to press the center button slightly before the power button. after pressing both, it shuts down and when you start it it opens on the starting video, lasts about 30 seconds then starts and says refreshing database. what is to be tried? BTW, i checked and the version of the firmware stays the same, it is not a way to reset to the original version of the firmware

Could someone with a v2 (of any kind) please plug it in and run
http://www.chiark.greenend.org.uk/~christi/misc/usbids.exe
if on Windows, and lsusb if on Linux and paste the output here?
And if you're feeling really generous fill in the table on
http://www.rockbox.org/twiki/bin/view/Main/DeviceDetection
In any or all of msc, mtp and rescue/manufacturer modes if available.
Thank you

Thanks a lot to both of you. Could anyone with a differently sized Sansa confirm that they get the same numbers (0781:7422 and 0781:7423)? This has been the case for all other Sansas so far, but you never know.
