Thanks looser

I used the file provided by looser and it worked. The margins are smaller now, so

Now, I would like to make the margins even smaller. Does anybody know which bytes should be changed for left and right margins ? (I've seen ixtab's entry on the first page but in looser's file, the numbers for left and right are unchanged and it still works)


a note : if you change the 'words per line' setting from the menu, you have to copy the file again in /var/local/java/prefs.

Note that I'm currently developing a major update for the entire patch framework, including the margins patch, so you may want to check back in a week or two.

how to change margins

OK,

thanks for that info about /var/local/java/prefs/reader.pref file.

If you want to change margins from command line, just change those \x028 bytes with something else using command tr, for example (assuming you are root):

mkdir backup
cp /var/local/java/prefs/reader.pref backup
cat /tmp/root/backup/reader.pref |LC_ALL=C LANG='' tr '\x28' '\x14' > /var/local/java/prefs/reader.pref

You should everything check using (before and after change)
cat /var/local/java/prefs/reader.pref|hexdump -C

Oh, I tried also other utilities (sed, awk), but only tr works on busybox on hexnumbers.

I've tried to set margins via JBPatch, but it does not seem to work, does anybody have this problem ?

I tried changing the margins back and forth as directed, but it only worked after I restarted the device.
Thanks

Yes, and that is also documented. ALL changes to the JBPatch settings require a restart of the framework before they are applied. The margin settings require the "back-and-forth changing" as well.

Hello all,

I've been trying to perform this hack on a K4, but I can't find the relevant prefs file. I suspect (as hinted at earlier in this thread) that the version of the Kindle OS on the K4 doesn't hold margin information in this file, and instead it's elsewhere on the system.

Did anyone ever work this out for K4? It seems like JBPatch isn't available for this Kindle, so that's out as an option.

(Please put me right on any obvious mistakes. n00b to Kindle JB matters.)

Can't wait to have a foolproof method for this one. This binary file swapping should work (I guess), but connecting the PW as an USB networked device is beyond me, unfortunately.

Due to the overwhelming demand, that'll probably be the next JBPatch bit that I'll try to port to the Paperwhite. So keep an eye on the JBPatch thread, but as always: don't hold your breath. It'll be released when it's ready and tested.
