Possible to replace some 500 files with 505 firmware?
I compared the content of the last PRS-500 update with the content of the PRS-505 content and noticed that a lot of files were identical, and that both had the same Linux distribution (they are library compatible).
So I was thinking: Would it be possible to replace some of the files manually from the PRS-500 (which doesn't seem to be updated any longer) with newer files from the PRS-505 update? There are files like FskDocumentViewer.so, FskBBeBViewer.xsb, or FskDocumentViewerRTF.so (RTF) which appear to have been updated (they all have increased filesizes in the 505 update). FskDocumentViewerPDF.so (~2.2MB) from the 500 has been replaced with FskDocumentViewerAdobe.so (~7.6MB), which now includes ePub support. Just curious if anyone else has given it some thought. |

Hi TadW,
Did you succeed ? I'd be interested just to get the reflow in PDFs. Personaly I tried to use the older firmware updater with the new .img files -> I bricked the PRS-500. I had to reset it ten times to reflash the lder firmware. Vapo |

As far as binary compatibility, the models are compatible, and there should not have been any problem to port the viewers (i.e. Adobe DE or PDF) to 500, other than perhaps the RAM really is an issue (hard to believe, but it is possible). |

How do you access the files in the distribution ? I tried to mount the .img files, but PowerIso or WinIso say it is not a valid format.

If your Linux distribution supports it, you can access the files like this (which is how I did it):
$ sudo mount -o loop cramfs.Fsk.img /mnt/sony/ $ ls /mnt/sony/ -la |

This is what I was thinking too. So basically, we could try to replace, let's say, the viewer binaries and repackage them in the cramfs image before reflashing it onto the 500.

Any news on this ?
I have not a great knowledge of PRS 500 OS tricks and not much time to hack...or maybe Sony will just provide an update for PRS-500 after all... |
