This patch will increase the time limit before sickel acts from 10 seconds to 20 or 30 seconds, giving a bit more time for slow tasks to complete. It should work with all firmware versions from 4.3.8842 to 4.5.9587.

Thanks for the patch, Geoff. I did experience this phenomena a couple of times on the latest FW. I was blaming the huge size of my books.

Are you sure you have the times right? My understanding was that sickel was triggered after a minute. It was a lot shorter when it was first introduced, but, when Kobo turned it back on, they said they extended it to 60 seconds. And that the reboots I have seen with big kepubs did seem to be after more than a minute.

sickel still starts a 10 second (10000 msec) timer, and the patch just changes the 10000 value to 20000 or 30000. But I'm not sure whether the reboot after opening large KePubs is caused by sickel or something else.

In any case the patch won't do any harm. If the reboots are not caused by sickel then it just won't have any effect.

I don't know any way to change the default fonts used for the user interface, not with these patches anyway.

You can sideload your own fonts, and if there is a glyph missing from the system fonts then it might be substituted from your sideloaded font. This works for things like book titles and author names, and for the patched keyboards, but it doesn't seem to work everywhere in the UI. There can be some problems with sideloaded fonts that don't have italic versions of the missing glyphs, and some fonts have other problems that prevent them working properly in this way.

Hi,

I have not updated my Kobo H2O for more than a year and now I went to the latest firmware. When I scroll down in my list of books, the display does not refresh and displays the various pages all at once. When I go the home screen, it looks like there are some watermarks. This is with the original firmware without patches. Reading itself is fine.

Does somebody have an idea?

Thank you in advance
Joachim

I see the same thing on my Glo: in the book everything is great, but outside the book the UI ghosts up farily quickly. I think it has always been like that to some extent, but perhaps a bit worse in the 4.x.x firmware, especially on the new home screen.

There is no patch to affect it. All I can suggest is to flick to sleep mode and back to force a refresh if it gets too bad.

Thanks alot for the workaround, that part is really buggy.

I have done a factory reset, this helped. It is ok now.

First, thanks for this patch. I love it and being able to get rid of the bottom footer and make my margins smaller. Much better now.
Second, got a question about the "search current read" function. I can search for a word in my epub but when I click on the result it takes me to the current page I'm on. Not the search result. Has anybody experienced this and does anybody know how to fix it?

Never mind. Got it sorted. Broke ePub when editing headers in Calibre. Search works fine. ����

What tool do you use to decompile the firmware and get the addresses for strings, for example to get: ValueDisplaySlider::setStep

Also, how do you get the addresses for the libadobe.so patches?

I already know about strings -tx -el

I am planning to work on some of my own patches.
