Changing configuration of MARGINS and FONT SIZES - possible?

[Waylander]

That's what I thought. Problem is I got a message saying Transmit couldn't get a "remote handle", which I don't know the meaning of.

You first need to remount Kindle filesystem as read-write before it allows you to add/write files to it.

Terminal command for that is:

mntroot rw

After you're done copying files just remember to switch it back to read-only:

mntroot ro

Also, did you setup the IP addresses on both end of USB cable?
Can't help you with SSH setup and client app on Mac OS.. I've used WinSCP on Windows...

[Waylander]

Aaaaaaaargh. I'm so stupid. Missed out those steps because it wasn't clear. Sorry for the lack of clarity. SSH is ok as I've rooted using Transmit on Mac so that's fine. Thanks for helping.

[Waylander]

OK, I enter "mntroot rw" as the Terminal command, but I get -bash: mntroot: command not found back. Did I miss a step pout before that would make this command work? I setup the IP address on both ends of the usb, following the instructions.

Hi!

I also get stuck at this point... You could follow my desperation in this thread.

Solution for me was:

1) Get connection over USB as you did.
2) Open SSH over a terminal windows on the MAC:
a) open a terminal window
b) type in: 'SSH 192.168.15.244'
c) type in the command 'mntroot rw'

Then you should get the right writing access.
After that, you can overwrite the file. I did it with the mentioned APP 'Transmit' which is free for a couple of days.

Try mentioned steps above.

Hi! Thankyou for your patience and clarity. It's much appreciated.

OK, now my Mac can't "see" my KOA. I've typed in the right series of numbers into IPv4 to try and connect it, but the network preferences are saying that it's not connected and the cable's unplugged, even though it worked before.

[Waylander]

Right, now my Mac can "see" my KOA as an RNDIS/Ethernet Gadget, but when I enter "ping 192.168.15.244" into Terminal, it doesn't come up with the list of numbers with "ms" at the end. Instead it comes up with "request timeout for imcp_seq" followed by a number. What have I done wrong now?

Sorry if the question is stupid, but would it be possible for you guys to create an extension for Kual to change the margin settings?
It would greatly facilitate for noobs like me who are understanding absolutely nothing of what is being said in this topic

I have suggested repeatedly that these changes to Java binaries should be distributed as the output of bsdiff so that they could be applied using bspatch.

When, if ever, the authors decide to do that -
Then yes, a KUAL extension could be made to do the job.

Prior to (about) firmware version 5.2.x, Amazon distributed updates as bsdiff files and used bspatch to apply them.
So this isn't exactly a new idea.

@knc1, it would be nice if someone made a extension like this.
I will stay here in the crowd that some charitable soul has pity us simple mortals who do not have the skills to program rsrs

Hello. I am trying to change the margins of a PW1 5.6.1.1 by editing the jars, but for some reason lateral margins are not modified.

I have edited the file ReaderSDK-impl-es-jar (I read in spanish) according to this great guide (thanks sprite7!). However, left and right margins are not modified.

First time, I just modified the numbers under "font.wordsperline.margin.list", since lateral margins are the ones I want to change (top and bottom margins are good for me as they are by default; same with the progress bar). But after modifying the class archive (and resetting the kindle, and later changing margins through the Aa menu to clear caché), nothing happened.

So I modified the file again, now affecting all the rest of parameters (progressbar.margin, progressbar.height, etc) as in the guide, just in case... But again, the lateral margins were not affected.

I can see now the changes in the progress bar and the top margin (smaller both), so those changes are working, but the left and right margins are still as default. Any idea about what could be happening?

Thanks!

As usual... once I ask something, I find the answer (well, at least I think I've found it):

For some reason, my class file has the "font.wordsperline.margin.list" repeated twice.

The first time it appears, it does as in the example by sprite7, like this (original file, not modified yet):

Spoiler:

ldc_w "font.wordsperline.margin.list"
aastore
dup
iconst_3
newarray atype:int
iconst_1
dup
pop2
dup
iconst_0
ldc_w 50.939998626708984
invokestatic int com.amazon.ebook.booklet.reader.resources.ReaderRe sources_es.pixVal(float)
iastore
dup
iconst_1
dup_x2
ldc_w 33.959999084472656
invokestatic int com.amazon.ebook.booklet.reader.resources.ReaderRe sources_es.pixVal(float)
iastore
dup
iconst_2
ldc_w 16.979999542236328
invokestatic int com.amazon.ebook.booklet.reader.resources.ReaderRe sources_es.pixVal(float)

Of course, that was the section I modified, because it was the first I found, and I didn't imagine it could be repeated later in the same file. But it is. This is what I have found now, near the end of the class file:

Spoiler:

ldc_w "font.wordsperline.margin.list"
aastore
dup
iconst_3
newarray atype:int
iconst_1
dup
pop2
dup
iconst_0
sipush 150
iastore
dup
iconst_1
dup_x2
bipush 100
iastore
dup
iconst_2
bipush 50
iastore
aastore
aastore
dup

Why twice? No idea, but it seems that those numbers (150, 100, 50) are the ones that my kindle is using for the margins, not the previous ones. I cannot try just now (I haven't the kindle with me at this moment), but I will try to change those figures... and cross my fingers

Well, from reading what little you posted . . . .

The first you found reads the scale factors from an integer array and converts them into a pixel count (to match the screen resolution).

The second you found actually loads the scale factors into the array.

There is no limit to the number of times a constant string value can be referenced.

But I suppose that the last reference it the one that counts, right?

Something strange is happening: after changing the second reference (50/10/150 to 10/20/30, for example), it works: I go to the Aa menu, I change the margins, and the three margins show as I want. However, as soon as I change the page (one page forward or one page rearwards), the margins change again to the default (well... not sure if as large as the default, but close).

Maybe I have to change both references, the "relative" and the "absolute" ones? It seems strange, I suppose the second one supersees the first one...

Maybe I have to change also the "reader.content.leftMargin" (and "rightMargin")? This was not included in the instructions to be changed in the posts I have read, but maybe...

Still trying...
