Instructions for patching firmware 4.17.13694

I did not come across any side effects with this. I'm not saying it doesn't need to be updated, just that without updating it things worked out for me.
I'm reading a side-loaded, converted Kepub.

Your mileage may vary.

I’m talking about the following

Missing patches:
- My 24 line spacing values (waiting for GeoffR to update).
- Custom font sizes (waiting for GeoffR to update).

Jackie and Jon, I've updated this patch and rewritten it (and the other power timeout one) to be multi-version. It will be released in v53 once GeoffR's patches are updated (if he doesn't show up in a few weeks, I'll figure those patches out), or you can copy-paste from GitHub or below:

Larger Sleep/Power-off timeouts:
  - Enabled: no
  - PatchGroup: Sleep/Power-off timeouts
  - Description: |
      Increase the available sleep/power-off timeouts to larger values (up to a
      few weeks). See https://www.mobileread.com/forums/showpost.php?p=3887105
      for additional values.

Thanks very much, especially for making it multi-version.

It installed fine and the Sleep after 8min option worked as expected. Hopefully the PowerOff after 24hours will work just as well.

No problem! I've also made a few more patches multi-version, and if I can wrap my head around ARM PLT relocations and string tables in a reasonable amount of time (and implement it in a reasonable amount of Go), I can make another 80% of the patches reliably multi-version.

I hope you don't think you're going to be putting your feet up during the next firmware upgrade.

ETA: I've still got a multi-version of GeoffR's 'My 10 line spacing values' that he posted once upon a time if you need it.

Are you going to be able to not read for 24 hours to test the sleep timer?

Well, possibly not, but I do have a lot of "spare" readers. I knew they'd come in handy one day.

In order to test the sleep timer, I can read on my phone or tablet. So that won't be much of an issue to do the testing.

That's the one I'm talking about, the actual entry is what I called it on the previous post.

No, you were talking about advanced font control which allows you to adjust the weight of sideloaded epubs. The patch I’m talking about removes the higher font sizes from the font size selection and adds additional smaller sizes to allow you to fine tune the size.

Custom font sizes is the actual entry name for this patch.

I've installed the patch. I've set the sleep timer to 26 minutes and it works well. Thank you.

The largest value I can seem to get to work is 255 which is 37 hours 8 minutes. Can I use a larger value then 255?

Yes, but you lose granularity for values in between (it's exponential). If you tell me the minimum and maximum values you want, I can probably modify the patch for you.

Hopefully. The biggest issue I'm having right now is I need to decode the PLT offsets, and I don't want to add a dependency on capstone.

ETA: I've still got a multi-version of GeoffR's 'My 10 line spacing values' that he posted once upon a time if you need it.

I decided against doing it at the moment because although they haven't changed recently, it's possible for the value substitution offsets to change silently. Also, how did you deal with the branches (the first 5 replacements)? Those are different every version.

[boopsy35]

thanks for the info..Is there a possibility that it' l come back? See I really like the new firmware but my problem is that without the greek keyboard I can't search for my greek books...and I wish I could do the amazing work that you do but I'm clueless...

[Sirtel]

A total noob question (I apologize if I've missed something glaringly obvious): how does one install individual patches, after installing the whole kobopatch in one bundle? Is it even possible?

And on that subject, how does one update the installed patches, when the new version of them is released? By doing the whole procedure all over again?
