Re: iRiver H300 bootloader once more

Hello Aura,

I have understood, that the H300 boot loader is currently broken, and
> flashing it will brick the device, am I right?

This is what I remember but it might not be true: Someone tried to flash a
newer bootloader and at the time it bricked his device. People then only
trusted a working version of the bootloader from specific commits. Newer
bootloaders might or might not work, but unless you have specific hardware
to reflash your device you shouldn't risk it.

Wow, so the official firmware files for H300s are now in oblivion?

Indeed it has been years since I last touched the bootloader part of
Rockbox, and I am afraid that my memory of this activity back then, is even
more faded.

In any case I looked at my archive and one of my H300 units that I have
with me and I found the following. In my Rockbox firmware archive folder I
have two patched H300 files named "H300 charging & usb boot button
enabled.hex" and "H300 r14945 and patch -
1e76f7ef071117b942555964300f8572.hex". If I remember correctly the first
one is about enabling USB charging at the bootloader level, the second one
I actually don't remember what "patch" is referring to (the hex number at
the end is an md5 checksum). In my H300 unit I probably (again I am not
100% sure) have the second file flashed, and from what I see the unit is
running the 1.31K iRiver firmware.

I can provide you the files, and although I believe they will work, it has
been ages since I last tackled with these issues so I cannot guarantee that
your device won't be bricked. On H100, Rockbox provides a plugin to dump
the flashed firmware, unfortunately I think this is not the case for H300,
otherwise I could dump the firmware from my unit so that you can be sure
that it won't brick your device.
