Change in this what you want (FSK\sony\ebook\application\resources (.xml files) or FSK\sony\ebook\application\resources\scripts (main.xml, icons and logos)
  3. Then with mkcramsfs.ese FSK Fsk.img will pack again the all files unpacked before.
  4. Now you have to create a md5 file checksum. Drag and drog Fsk.im above md5Sums.exe, so it will open a window with a serie of numbers and letters.
  5. Open with notepad the file Fsk.img.md5 content in the folder of installer, and editing with the new code generated before with md5Sums.exe.
  6. Copy the new Fsk.img into the folder of the installer replacing previous.
  7. And introduce a sd card with previous all files, and follow the steps run installer with expert mode, update firmware PRR+.

Note you have cywgin, cramsfsk, mkcramfsk, and md5sums.exe and the different libraries. this tools you can get http://code.google.com/p/prs-plus/so...d#hg/505/tools
Thanks, Victor. When remaking the Fsk.img file, I get the following:
Code:
C:\Users\dow.HOME\Desktop\New folder>mkcramfs.exe FSK Fsk.img
warning: gids truncated to 8 bits (this may be a security concern)
Should I be concerned about this warning?
