Hi welshkid!
Welcome to MR!
I would recomend to wait until kartu will have finished porting PRS+ v2 to PRS-505.
But if you can't wait follow this instructions:
First of all you have to install PRS+ 1.1.3 from
here
Then you need my patched version of "ebook.so" version 1.1.00.18040 and a modified copy of "main.xml". Copy both along with your prefered standby-picture (named "kBookStandbyPic.png" -all case-sensitive) into the root of IM of your reader.
Then place a "prsp.sh" script-file in "/database/system/PRSPlus/" with this content:
Code:
cp /Data/ebook.so /tmp
mount --bind /tmp/ebook.so /opt/sony/ebook/application/ebook.so
cp /Data/main.xml /tmp
mount --bind /tmp/main.xml /opt/sony/ebook/application/resources/scripts/main.xml
Check for UNIX (LF-only) format.
Restart your Reader.
If all works out, your standby-picture is shown after flipping the power-switch. If instead the last page stays on screen, power on again and hold the switch a moment longer next time.
If there are any problems, start up your reader conected to the USB-Port. This way the prsp.sh will not be executed and you can access the reader via file-explorer and modify or remove the file(s).
Please notice that the patched ebook.so also changes the behaviour of rotate. (Holding Zoom-Button). Each "doRotate" turns the screen 90° to the left, instead of switching between normal and rotated.
Feel free to ask if things remain unclear.
best regards
Mark
