Sony Reader PRS-500 universal flasher

So here it is. From the readme:
Quote:
This set of scripts allows to flash a custom image or replace any files inside
the /opt directory of the Reader filesystem using just a flash card. The /opt
directory contains the main Reader UI and supporting files.
Possible uses include:
1) rolling back to an older firmware version
2) customizing the UI look and behavior
3) replacing/adding built-in fonts

As an example, provided xml files add a configurable clock display in the
status bar of the navigation menus and book reader.
Version 1.2: support for firmware version 1.0.02.01300
Version 2.1 with support for firmware version 1.0.03.07170.

Does this clock work with the current firmware or will it brick the reader?

Perhaps one of our fearless testers or careful machine openers might do us the favor of testing this program - hopefully it can be used to add/change some internal fonts?... I will gladly up the Karma to such brave souls....

Yes, the clock will work fine with the latest firmware. As for the fonts, consult the readme, I have some details listed.

Now I have to find my card reader and see if it supports SD. Otherwise I'll need to buy a new card reader.

You could use your SONY reader as a card reader ;-)

If the internal fonts are changed, then the speed of screen redraws is faster than for an embedded font - i'm guessing?

I'd expect you might not need to embed the font in the first place.

I just glanced over the code and I am more than impressed by Igorsk's work (and Corwin's, and Shade's)... very cool stuff!

So is it save now to upgrade the Reader with the latest firmware without losing USB access?

Yes, the script flashes the firmware directly, without using the USB protocol. So you don't need a signed FS image to use it

Thanks Igorsk for this!

I tried it with the new firmware and he keeps saying: "stat_fs not found". Any idea what's going on?

Hm, this is strange. Do you have "stat_fs" in the "bin" folder on the card?

Yes, I extracted the contents from the zip to the SD root and stat_fs is in the bin folder.
