Hi,

My Glo HD screen had frozen some month ago. I tought it was dead, the warranty period was over and i opened it to reuse the 4Gb SD card elsewhere, deleting an formatting it.
Since this time, I have seen that i could buy a new replacement screen on Ali_something_very_quick and so i could repair my e-reader (or try to do so :)).
But the problem is that i do not have no more a system SD card available.
Please, does anyone know how to obtain a working system image to dd on a new SD card ?

Best regards

KSM touch driver and rotation test

With each release of a new Kobo reader there arises the challenge to find out whether KSM will work on it, especially whether one of the available touch drivers can be used and which rotation values to set. Therefore I would like to provide a tool that facilitates this process.

Installation (I assume that KSM is not installed on the device):
  • Extract the file KoboRoot.tgz from the uploaded archive and copy it into .kobo of your Kobo reader
  • Eject and disconnect your Kobo reader from the PC
  • Wait until the package is installed and the device restarts
USE AT YOUR OWN RISK

Are there additionnal reading statistics available while looking in the databases?

Hello!

I am especially interessed in finding a way to see how much time I have spent which day (or which session) and how many pages I read which day (or which session), ideally for every book independently.
I don't think everything is stored indefinitely, but since some statistics such as the average session time for every book and the amount of pages per minutes are made available, I think that information such as a list of the sessions for each book, including the timestamp of the beginning of the session and the timestamp of the end of the session, and the page number for both, should be stored.

Were is stored this information? Can I read it from a database (for example in .kobo/something.db) ??

Thanks in advance !!

Hi, this is my first thread. I am pleased to be here.

I have got a doubt:
Is it possible to choose the download directory in the kobo web browser?. I want download an epub to my library dir, not to root dir.
Any conf file?. Where?.

And I'm observing that the internet connection asks me for the router password from time to time. Someone else?

Kobo system cannot recognize fonts added into system-wide fonts directory?

December 7, 2018, 8:15 am

From Another thread:

https://www.mobileread.com/forums/sh...1&postcount=88

if you are really curious why I want to add fonts into system-wide directory why not just sideload those fonts, please check the context of that thread.

Using patch system, I successfully deleted several fonts in kobo system-wide fonts directory(/usr/local/Trolltech/QtEmbedded-4.6.2-arm/lib/fonts/), and they are no longer in the drop-list of changing-font in reading page.

But when I tried to add fonts into kobo system-wide fonts directory, the fonts I added are not in the drop-list(BTW, the fonts I added are working fine when sideloaded), so I did a little trick, add the following line to the end of the shell script which removes the fonts to list all fonts in /usr/local/Trolltech/QtEmbedded-4.6.2-arm/lib/fonts/ and print the list into `nickel home` directory:

ls usr/local/Trolltech/QtEmbedded-4.6.2-arm/lib/fonts/* > /mnt/onboard/fonts-list

So I check the list in fonts-list when I connect my Kobo to PC. And the fonts I added are exactly all in the list(as expected, the fonts I deleted are not in the list). It means I did add them into usr/local/Trolltech/QtEmbedded-4.6.2-arm/lib/fonts/ but Kobo cannot recognize them when I want to change fonts when I'm reading. Why is that?

And I notice another thing, when I extract the kobo firmware zip file and try to open *ANY* font in the kobo-update-4.11.12019\KoboRoot\usr\local\Trolltech\QtEmbedded-4.6.2-arm\lib\fonts, it failed to open it.

Double left-clicking it in Windows10, it says

"The requested file xxx is not a valid font file."

And I tried to open it using FontForge, it failed to open it too, it says:

"xxx is not a known format (or uses features of that format fontforge does not support, or is so badly corrupted as to be unreadable)."

That is so weird.:help:

I would really want to use a web application of mine on my Kobo, but it uses some recent Javascript which, despite of being nowadays supported by every web browser, are not supported on Kobo Nickel's.... Is it possible to launch Firefox or GNOME Epiphany from KSM ?

I think I've gone over every thread there is and couldn't find an exact answer or guide that would enable me 2 change Kobo's default translation options.

I really do need be able to translate whole fragments from german to English. I wonder if there is some patch to would use "search Google" in order to send the query to Google translate.

Any help would be appreciated, certainly such that won't run the risk of bricking.

RGB Leds

Hi All,

Ordered a Kobo Clara HD as I really like idea idea of Comfort Light Pro. (Placebo? Probably.)

A few reviews mention that Kobo is using RGB leds to get this effect. If that is the case, it seems like it should be rather easy to modify the LED driver to change the color of the screen to any RGB combination.

As this has not been done yet, my guess is that they're actually using orange and white leds and just mixing the color.

Has anyone else looked into this and found it to be impossible (i.e. they aren't true RGB leds, all four pins aren't hooked up etc.) before I waste time reverse engineering the driver?

I haven't worked with a Kobo before, so anything else I'm missing? I'm assuming I can easily root this thing and login via ssh for development.

Cheers.

Difference between Rakuten and Walmart purchased Kobo

I bought the Clara HD from Walmart this past week, and was a little surprised to see Walmart branding on the device itself. There is a Walmart logo as the default screensaver, and Walmart login is the primary method.

Are there any other significant differences?

Would there be any strong reason for me to flash the non-Walmart image?

Honestly dealing with Walmart was rubbish. They said two day shipping but it ended up being four days.

Upgraded Clara HD to 256GB SD Card

This morning I upgraded the 8Gb SD card to a 256Gig card. The new card is a Class 10 SDXC one.

I used Arch Linux, dd, GParted. The whole process took about 40 minutes.

1. Use `dd` to create an image of the card: dd if=/dev/sda of=~/kobo-clara-had.img bs=4M
2. Use `dd` to image the file to a new 256GB card: dd if=~/kobo-clara-had.img of=/dev/sda bs=4M
3. Use GParted to resize the /dev/sda3 partition
4. Reinsert the SD card into the Clara
5. Boot, it will show there is an error, and choose "Factory restore"
6. Re-setup, and login, and it's ready to use. During this step it also downloaded an update from the internet.

64gig replacement being routinely done by users in this forum and I think it is the most cost effective size. The hardware is capable up to 128gig in theory.
I am pretty sure that as long as the card is SDXC it will work in the Clara HD, even if it's the 400GB card I almost bought.

Warning: If you plan on using this method please ensure that you are using the correct device ID. Mine was `/dev/sda` but yours could be different.

Devanagari, Sanskrit, Hindi

December 17, 2018, 3:14 pm

This is my trial to adapt the Kobo reader for Indian languages that use the Devanagari script. There are several issues of which I deal here only with the keyboard.

Step one: Since we need a lot of characters, we set the local language of the OS to Russian so that we can make use also of the Cyrillic keyboard in addition to the English keyboard. A disadvantage of this is that informations that are provided directly by the OS are displayed in Russian. But these cases are not too many.

Step two: We have to assign Devanagari letters to the keys. This involves overwriting parts of the binary file libnickel.so.1.0.0. There are several tools to do this. I used the patcher of "Modifications for bad eyes".
One of the problems is that some characters/parts of characters are not shown on the keyboard, namely non-initial vowels, anusvara, anunasika, and virama. My solution for this is to assign these signs to positions on the keyboard that can easily be remembered. I assigned the virama to the key under the key of the initial "a", the non-initial vowels under the keys of the corresponding initial vowels (that means non-initial "long a" under initial "long a" and so on). I assigned the anunasika to the key left of "ma", the visarga to the key left of "ha", the virama to the key under initial "a", and also to the key left of "va".

I did this for the keyboard layout used by Kobo Touch and so on. For other devices this will need adaptations, or might not work at all.

On the extended keyboard there ares still some positions available for the Hindi specific characters, which I did not deal with.

I've been looking at the firmware, and noticed two IDs for the forma: 377 and 380. I think they are for the different storage sizes. Can someone with the 8GB and someone with the 32GB Forma post their device ID (it's in .kobo/version) so I can make sure I know which one is which?
