That post is a worked, step-by-step, example of the commands to run (if on Linux or in a Linux VM) to find the FONT_RAMP string in the Java binaries.

Underneath the GUI(s), Linux and Mac OSx both derive from Unix systems -
You'll find many similarities at the command line level.

For a little practice (since your Kindle runs Linux, not just an academic waste of time) -
Try playing with a Linux Live CD (which doesn't change anything on your Apple, Pear, Peach, whatever).

This is a popular one -

Did you have the Backdoor lock installed and locked?
Did it prevent the automatic update, so that you had to manually allow the update?

No, device wasn't jailbroken. Backdoor lock was not installed. I manually copied BIN and updated KV.

The bridge should theoretically still be effective w/ 5.6.2.1, the basics should survive the trip. Whether anything actually works after that is anyone's guess, though .

The keyword being *theoretically* since I'm still not running 5.6.x on any of my devices .

What if I have a Pineapple? Just kidding! Thank you, I will check it out!

P.S. FONT_RAMP working for me too on 5.6.2.1. No jailbreak. Curious why Amazon has allowed this. An oversight they will eventually correct or intentional relaxing of tight control?

[eschwartz]

This would have to be pretty deliberate.

Ooh! I like the sound of that!

Possibly as a replacement for the "use alternate fonts" feature -

Which caused them, their users, and us no end of trouble (a user supplied, bad font file can seriously brick a Kindle).

I just got my Kindle Voyage with 5.6.2.1. The trick with /mnt/us/FONT_RAMP does not work for me.

Did anyone else have any trouble with this?

Only those who used the example that had a few of the values using ',' for the decimal point instead of using '.' .

It is strange. The file is Unix-ending (still irrelevant as there is no line ending). Uses dots, not commas. Is placed in the usb root. Is named as it should. Still wrong.

I should reboot after each change of the file contents?

LE: I was testing with mobi files. As I understand, with these it does not work.

Would something similar work with margins? I would really like to get the bottom margin lower.

[eschwartz]

No, this requires vanilla firmware support as it is shipped by Amazon. As far as we know, they have only left a configuration option for the font sizes.

You would have to block or hide the information bar at the bottom of the screen.
It may be a bit hard to see, since it has a white background, but it is there.

Hmm....
Perhaps a modification of 'fronter' could move that bar to a hidden layer so that area could be used for page viewing.

But whatever, you will have to jailbreak the device to gain access to the full file system.

[Waylander]

Oh well, that's that then.

Thank you!
