To be more precise, do you mean that the Footer Patch needs to change from

replace_xor_D3 = 13BE688, `ReadingFooter... etc... etc... for fw 3.0.0 to

replace_xor_CC = 13EA170, `ReadingFooter... etc... etc... for fw 3.0.1?

Yes. At this time, it means Metazoa needs to update and add another XOR handling routine. I haven't seen the python source but I'm wondering if it could be modified to pass it the XOR value so the routine would not need to be modified each time. This would be handy for me since the 4 major patches I use could be applied without needing to wait for a new patcher.

And that's it?
All I've to do is to change a few Bytes within the 'kpg.conf'?
This will make V.10 of the patcher work with FW 3.0.1.?

As I said some posts ago, I can confirm that the routine is written in a flexible way, so that it can take and value up to FF.

That is it. But don't forget to replace the libnickel.so.1.0.0 with the one of FW 3.0.1, and to disable any patches we don't know the new values of.

PeterT,

would you please add the link to the patcher version 10 to the fist post of this threat? Cf. this post for the link, and the one following it for a description.

Where do I get the 'libnickel'-file?

...and to disable any patches we don't know the new values of....

Well, I already patched
- Line Spacing Values
- Custom Font Sizes
- Custom L&R Margins
luckily without Problems. Thx for the warning..

You can find the FW update files here. It does not matter, whether you take the one for mark 3 or 4 for our purpose. Unpack its content and find the libnickel file in usr/local/Kobo.

I wonder, how this could be possible. Did I understand correctly that you applied the patch with the new address values (provided by GeoffR) to the old libnickel file? Didn't you get error messages?

I applied a kpg.conf to the old libnickel which only had patches for margins, line spacing and font size in it.
And no, didn't get any errors.
I did not bother with all the other patches. They where deleted prior to the applying.

...Unpack its content and find the libnickel file in usr/local/Kobo. ..

Can't find that path within the FW.zip.
Is it hidden?

Unzip kobo-update-3.0.1.zip, you will get KoboRoot.tgz; un-gzip KoboRoot.tgz and you will get KoboRoot.tar; untar KoboRoot.tar and you will get some folders.
Depending on the program you are using, un-gzip and untar might be achieved with a single command.

Be aware that if you put the newly created KoboRoot.tgz file to your reader and something went wrong you will have to factory reset your device.

Here is the `fix page breaks bug` patch for firmware 3.0.1 (644485e229)

Spoiler:

<Patch>
patch_name = `Fix page breaks bug`
patch_enable = `yes`
replace_bytes = DDD556, E8 D0, E8 E7
#Alternative method
#replace_bytes = DDD556, E8 D0, 00 46
</Patch>

I've also updated my program for applying patches from Linux in this post. It can now apply all of the 3.0.1 patches except the cyrillic keyboard patch. It has a slightly different syntax for the xor encoding, but to apply the 3.0.1 footer patch for example just change the patch from this form:

Spoiler:

<Patch>
...
replace_xor_CC = 13EA170, `...`, `...`
...
</Patch>

to this:

Spoiler:

<Patch>
...
encode_xor8 = CC
replace_string = 13EA170, `...`, `...`
...
</Patch>

Although I don't normally use the footer patch myself, I've briefly tested it on my Glo with firmware 3.0.1 and it seems to work OK.

Start the kpg.exe from the command prompt window (cmd). If you start it by double-clicking, the program's window closes before you can read the messages.

Are there Windows programs which can deal with gzip and tar?

I use 7-zip.

Well...
What I did
1. downloaded FW 3.0.1
2. upgraded Aura HD to 3.0.1
3. downloaded Patcher V.10
4. extracted libnickel from FW 3.0.1. package
5. replaced the libnickel-file within the patcher folder (3.0.0) by the extracted 3.0.1 version
6. edited the .conf as follows:
<Patch>
patch_name = `Custom reading footer style`
patch_enable = `yes`
# Decrease footer example
replace_xor_CC = 13EA170, ...
</Patch>
7. run kgp.exe

And got the error message: Data for libnickel and kpg.conf does not match.

What's wrong with my attempt?
