Kobo Patcher

[Nick_1964]

Damn, I wish there was a patch that switch my reader off for upgrades, I need to sync for some books and BAM, I am on 2.10.0 just downgraded again but I am afraid that there will be a time that the upgrade won't allow to downgrade again.
So please, can someone find a way to allow synchronisation without updating ?

(but if someone could post 2.10.0 as upgrade file so I can inspect it safely and not on my reader, I would be gratefull, like the 2.8.1 posted early here.. just to be sure that when it is patched, I can upgrade without connecting to kobo again.)

Now I gonna place the modification from tshering back.

It was 3 AM and I was in bed, changed it into 2.10.0 but for the question it is not important, I just don't want those updates.
I turned it off very quick but get the question, do you want to upgrade now or at the time you put on the device or something, with yes and no, but no doesn't work.

The way not to get 2.10.0 is to not turn on WiFi at all for any reason.

Cf. this post. If you apply it at all, take method (2), since this will enable you to install patches and upgrades if you wish so.

Again.. you are the man !!!

But as far as I can see this does not apply on the reader itself by wifi, but on the desktop program,because these paths are not found on my Kobo Aura HD.

Nick_1964,

maybe I should mention that one has to use an editor that writes only line feed at the end of lines, rather than carriage return and line feed. If something goes wrong with the the rcS or usb file, one has to do a factory reset.

I can't find the files at all, so if this are the android system files I can't reach them, I would use an editor as notepad++ but I can't find the path, or do I reach it by telnet ?

Is there maybe a much more easy way ?
There is a version file in the kobo directory.
Maybe someone on 2.10.0 can post his one ?
If I replace it,hopefully the update server thinks I am on 2.10.0 and does not send an upgrade ??
Worth to try.

Since this is OT, I put it into the spoiler

Spoiler:

There are several ways you can achieve your goal. I describe one of them here. I do this under the assumption that you are using Windows and 7-zip is installed on your system.

Step 1 (decompress KoboRoot.tgz)
I guess you have the file KoboRoot.tgz of FW 2.8.1. Decompress this file twice (with 7-zip). First you get KoboRoot.tar, if you decompress KoboRoot.tar you get some folders with subfolders and files.

Step 2 (edit two files)
The two files we are looking for are
[CODE]usr\local\Kobo\udev\usb
etc\init.d\rcS[CODE]
Edit these two files (replace all occurrences of KoboRoot.tgz with xKoboRoot.tgz).

Step 3 (create the paths C:\KoboRoot\etc\init.d and C:\KoboRoot\usr\local\Kobo\udev)
-Open the command prompt window (cmd) and execute the following four lines (press ENTER after each line);

md C:\KoboRoot\etc\init.d
md C:\KoboRoot\usr\local\Kobo\udev

Of course, you can create the folders also with explorer, but this is tiresome. (Upper and lower case is important!)

From now on we use the explorer.
Step 4 (put the modified files to their new locations)
Copy the rcS file to C:\KoboRoot\etc\init.d, and copy the
usb file to C:\KoboRoot \usr\local\Kobo\udev.

Step 5 (compress)
Navigate to C:\KoboRoot. Select etc and usr. Right-click and select 7-zip > Add to archive ... Choose Archive format: tar. Press OK.
Right-click in the explorer on KoboRoot.tar, select 7-zip > Add to archive ... Choose Archive format: gzip. Change the archive name from KoboRoot.tar.gz to KoboRoot.tgz. Press OK.

Step 6: Copy the newly create KoboRoot.tgz to the .kobo folder of the device.

From now on your device might download the update files from Kobo, but it will not install them. If you want to install an update file rename it to xKoboRoot.tgz.
If you want to install a pached file via KoboRoot.tgz, or anything that uses a KoboRoot.tgz file, you have to rename it to xKoboRoot.tgz.

Be aware that when Kobo prepares an update, it puts apart from KoboRoot.tgz also a folder "update" into .kobo. It is important that you delete this folder before you install anything via xKoboRoot.tgz.

If memory servers correctly, some people reported that this did not work since a certain FW. There are also references to the FW in Kobo eReader.conf. Would be interesting to know how it is decided whether to download an update package.

Thank you for the explanation, with total commander i can go directly into the file.
About the version file... it has a number, then 2.6.35.3,2.8.1,2.6.35.3,2.6.35.3
2.8.1. is in the middle, then a decimal part.
I don't know if the number at the beginning is unique for my device.
Maybe I try tomorrow to save the old version file, trigger the server to send an upgrade ( if that is possible, else I hope someone will post the upgrade to 2.10.0) and compare the new version file to the old one to see what has changed ?

[PeterT]

I see!m to remember that the version file is now regenerated by Nickel removing user changes to it.

This number is the linux version. Edit: I misread your post. You are right, the number before 2.6.35.3 is unique.

Thank you, about your post: https://www.mobileread.com/forums/sho...&postcount=384
In step 4 do I have to copy the modified files to the new created paths, or do I have to move them to the new paths ( so delete them from the original place ? ) sorry for being such a noob.

As for our immediate purpose it does not matter: You can move or copy the two files. In my description I had the idea: 1) extract the whole content of the original KoboRoot.tgz (this is not economical, but easy to describe and easy to achieve with some mouse clicks), 2) edit two of its files, 3) move or copy them to a new location, 4) delete the extracted content. This would not have done any changes to your original KoboRoot.tgz.
Since you are using total commander for unpacking (and maybe loading the files to the editor), things might be a little different. Anything you do with the rcS and usb files, might effect the original KoboRoot.tgz, rather than the extracted content. I am not sure about this, since I don't use total commander myself, but if this is the case, I would rather copy the two files to the new location. In this way the now modified "original" KoboRoot.tgz would remain operational.

After rethinking it, I would change my description. 1) copy the two files from the original KoboRoot.tgz to the new location 2) modify those two files in their new location 3) pack the two folders etc and usr into a new KoboRoot.tgz.

Sorry for inconvienence.

No inconvienence here my friend, it sounds perfectly clear to me.
In another treat I heard that editing the version file does works, until you restart the device ( which I never do, it is always in sleep mode ) then it will be overwritten, so maybe I gonna play with that to, make it read only or so.
