c240 won't boot

<< < (2/4) > >>

Llorean:
If you're in the original firmware, and USB mode isn't working, something stranger is going on. Rockbox's bootloader doesn't interfere with the functioning of the original firmware. In fact, even after you install Rockbox, the way to get files on your player is to turn it off, plug in a USB cable, and wait for the original firmware to come up and connect.

Perhaps try rebooting your computer, and make sure you're not plugging in via a hub.

Thanks very much for your reply again.

My problem is that the c240(at least my c240) has never gone into file transfer mode by connecting the USB first.  If I do that, it will charge, but it stays in play mode.  The only way I've ever been able to get into file transfer mode is by starting the player, then once it's done refreshing media, connect the USB cable.

My problem now is that I can't start it first because it freezes on bootup.

I don't dispute that:

1) I caused this problem to occur
2) It's related to something I did, and not Rockbox firmware

however, minutes before I attempted to install the rockbox firmware, I uploaded files to the player and seconds after I attempted the install, three computers that could previously connect with the player were no longer able to.

I think I could probably properly install the firmware or remove the bootloader if I could only get to the data transfer mode, I just can't figure out how to do it.

thanks,

Well wait, I'm confused. If you're in the original firmware, what happens if you unplug the USB cable, let it refresh media, then connect it?

Also, have you tried booting your player into recovery mode, and copying over a PP5022.mi4 from an official firmware update? (DO NOT EVER COPY ANYTHING BUT A SINGLE OFFICIAL MI4 IN RECOVERY MODE: Obligatory warning)

Hi there Paul,

If I unplug, then reconnect while in the official firmware, it will charge the battery, but nothing else happens.  It doesn't seem to do anything really.

I didn't know that I had a "recovery mode"!

I found these instructions on the forum(for c250, but thought it would pertain to the 240 as well)


--- Quote ---1)turning off the c250
2)turning it on
3)putting the hold button into lock
4)pressing on the Previous/Rewind button WHILE plugging in the USB cable
(the USB cable already plugged into the computer's USB port)
as indicated in these two links

--- End quote ---

but of course that doesn't work for me because I can't turn it on before activating the hold button, since nothing boots up.  If I follow these instructions, it just does what it always done when I connect.

I'm still trying everything I can think of, but so far, I've not gotten much for my trouble :)

thanks,

Hey there,

I found the proper recovery mode method, and I'm in!

I have a problem though:  How do I find the file you specified?  Sansa updater now finds it, but says that it's up to date.  bootloader still doesn't see it.  I can see E drive again, but there's nothing but version.txt in it.

I visited Sansa's firmware page but it seems that nothing is offered for the c200 in particular, only offering me the updater software.

I've not found anything on how to proceed in Google yet.

thanks,
