Instructions for patching firmware 3.16.10

[GeoffR]

Before starting:

1. Make sure your Kobo ereader is already running firmware version 3.16.10 (f9fa4bfb12). Note that this firmware version was only officially released for GloHD devices sold in Japan.

2. Check that your battery is well charged.

3. Note that in Windows 8 the instructions below might require the batch file to be run in admistrator mode.


Patching from Windows, Linux (i386/x86_64), or Mac (OS X 10.8-10.9, i386/x86_64):

1. Download and extract patch_kobo_31610.zip (attached). [WARNING: If using Windows, make sure the path to the extracted files does not contain any '&' characters.]

2. Download the Kobo firmware archive version 3.16.10 for your device (See this thread) and copy it into the 3.16.10_source/ subdirectory. (Don't extract.)

3. Read and edit all the *.patch files in the 3.16.10_source/ subdirectory in order to: choose which patches to enable (patch_enable=`yes`) or disable (patch_enable=`no`); and to change some of the replacement values to suit your device and preferences.

4. In Windows double-click 3.16.10.bat; For Linux/Mac open a terminal, change to the patch_kobo_31610/ directory, and run ./3.16.10.sh from the command line.

5. If there were no errors, copy the resulting KoboRoot.tgz from the 3.16.10_target/ subdirectory to the .kobo directory on your ereader.

6. Safely eject and unplug the device, which will then update and restart.


To return your ereader to its original unpatched state:

1. Edit all the 3.16.10_source/*.patch files to disable all patches (set patch_enable = `no` for every patch).

2. Repeat steps 4-6 of the procedure above.

Notes:

* I haven't tested these patches at all, because I haven't installed this firmware version on my Glo. You might want to wait until someone else has reported that they work before using them.

* The `Wi-Fi insomnia` patch is missing, the Wi-Fi watchdog functions have completely changed in this firmware version so a new patch will have to be worked out.


More patches:

Disable pinch-to-zoom font resizing (libnickel.so.1.0.0.patch):

Spoiler:

<Patch>
patch_name = `Disable pinch-to-zoom font resizing`
#
# Prevents the pinch gesture resizing the font when reading k/epubs (on Aura
# or other devices with a multitouch kernel). Pinch to zoom images still works.
#
patch_enable = `yes`
replace_bytes = 8C8120, 04 46 2D ED 04 8B, BD E8 F0 8F 00 46
</Patch>

If you know of any other patches for firmware 3.16.10 post them in this thread and I'll add them to this post.

Is there a way to patch the auto-rebooting so it doesn't happen?

sed -i -e s/reboot/rebarf/g /usr/local/Kobo/sickel

The patches I've enabled so far are working on my test Glo. Since I rarely read kepubs and there aren't any on the Glo at this time, the kepub patches have not been tested.

I'm not sure that will do what you want, I think it will just prevent the sickel executable from running altogether.

"reboot" is the name of a function dynamically linked from libc.so.6, so changing it in sickel should cause a relocation fault when sickel starts.

Yes, that's what I assumed but - it actually runs, it runs, it pings, it works in every aspect, but when it actually triggers the reboot - it dies, with relocation fault, and nickel (if still alive) subsequently starts a new instance which is back in ping-mode.

is there a new version of the "Re-enable LeanAndMean touch gestures" patch for 3.16.10?

No, anything to do with LeanAndMean only applies to firmware 3.15.0. If you added the LeanAndMean=false feature setting to your config file in firmware 3.15.0 then it will probably still be there after you upgrade to a new firmware version, but it won't do anything.

I didn't removed it,and it is still there, together with the option ShouldDither=true , is support for this option also gone,or not needed anymore ??

The ShouldDither feature setting disappeared after firmware 3.14.0. Since 3.15.0 there is a highQualityDithering reading setting (not feature setting), but I don't know if it does the same thing.

Okay, thanks
