I might add some of these as I get time, but others will have to wait until a firmware version is released for other devices including my Glo. But if anyone else has patches for firmware 4.0.7523 post them here and I'll include them.

@GeoffR,

what's the prognosis for the keyboard patches? Is it just a matter of time and firmware availability or has Kobo changed something in a way that may prevent you from being able to discover them at all?

I'm not sure yet, something has changed to break the old keyboard patches, but I haven't looked very hard yet so it might just be something simple.

Finding the brightness file control patch will probably have to start from scratch, the light controls have changed completely.

The sleep/power timeouts patch was broken because the strings that are used for the menu have been optimised by the compiler, they now overlap in memory to save space, and so some of the menu items can no longer be changed independently. A more limited patch that just changes some of the menu options should still be possible.

To be honest, given that Kobo is supposed to be coming out with a new firmware soon, I would leave the keyboard patches alone and wait for the new firmware before trying to find them.

The main thing is that the encoding has changed. Previously one character was 4 byte, now one character is 3 byte.

Except that Kobo have changed enough things in this firmware that the more work done on it now will mean the faster the patches for next firmware will appear. And as you are someone who's first post after a firmware release is "When will the patches be available?", it's in your interest to encourage this as much as possible.

Thanks tshering, with that I've adapted the keyboard patches below (all go in libnickel.so.1.0.0.patch):

(Edit: these are untested, probably don't work on the Aura One.)

Cyrillic keyboard:

Spoiler:

Arabic keyboard:

Spoiler:

Hebrew keyboard:

Spoiler:

Turkish keyboard:

Spoiler:

Bulgarian keyboard:

Spoiler:

Greek keyboard:

Spoiler:

Things to check:
Does the upper-case still work on the `ß` key (for those languages with upper case.)
I don't think 3-byte codes will work anymore, this affects one key on the Turkish keyboard.
Is the Aura One keyboard layout the same as the H2O/GloHD?
The extra keys on the top row of the Touch/Glo/Mini/Aura can't be replaced anymore.

Edit: if anyone is running this firmware on an Aura 2ed. or a Touch/Glo/Mini/Aura could you describe or post a screenshot of the keyboard layout? Is it different to the layout shown in the screenshots in this post?

You might take a look at the modification of bad eyes patch for FW 4.0.7523. In part 3, I was to lazy to figure out which Arabic character should be there, so I simply took for the time being "x" as a placeholder.

Bald Eagle · 10-03-2016, 10:47 AM

Extended characters layout on the KA1 is completely different from the one on the H2O (and, presumably, all others, too).

Thanks, so the keyboard patches in post #22 won't work properly on the Aura One.

I don't know how that layout is constructed though, so what would help is if someone with an Aura One could try one of the keyboard patches in post #22 and see what happens: does it have no effect at all, or does it change some of the keys but result in a jumbled layout?

Bald Eagle · 10-05-2016, 02:59 AM

I did not even try to apply the patch because I don't think that

Code:

find_base_address = `æ\0à\0è\0ì\0`

would work with the KA1 layout.
Hmm, maybe

Code:

find_base_address = `ý\0à\0á\0â\0`

What will go wrong if there is no match?

You get an ERROR because it can't find the address, and it will not create KoboRoot.tgz file.

Bald Eagle · 10-05-2016, 05:39 PM

I stand corrected, the patch applies with the old find_base_address statement.

With the new key order the cyrillic patch now reads as follows:

Spoiler:

Since the lines are shorter than a standard keyboard the second, third and fourth row end keys flow over into the top row, the second to the right of top row, the third to the left and the fourth to the right again, as follows

Code:

ё э(from 3rd) [unchanged keys] ю(from 4th) х ъ(from 2nd)
й ц у к е н г ш щ з
ф ы в а п р о л д ж
  я ч с м и т ь б

GeoffR · 10-05-2016, 11:00 PM

Thanks for testing that Bald Eagle.

With such different layouts for different devices, maintaining patches for each combination of language and device is going to be a lot of work. As well, the Aura One keyboard has fewer keys than the other devices, and I don't know how the layout of the custom keyboards should be changed to fit.

This is a Keyboard template patch for the Aura One, it just needs the replacement keys to be filled in according to this pattern:

Code:

Row:  Position
---:-----------
Top: 0123456789
2nd: 0123456789
3rd: 0123456789
Bot:  12345678

Keyboard template (Aura One), paste into libnickel.so.1.0.0.patch:

patch_name = `Keyboard template (Aura One)`
patch_enable = `yes`

Hello GeoffR,

thank you for identifying the base address and the remaining characters of the top row.
I thought about that only after I had already posted my layout patch, by then it was already late at night and I moved it to 'later'. Now I can customize the top row a bit more and move in some characters I like better than the ones there

.

Your patch collection is awesome and makes the Kobos even better than they already where.

Thanks a lot!
