Kobo Bug thread

Busybox zcat does not throw any errors at all.

Real zcat would throw an error, unless the cutoff happened to be a valid boundary.

tar throws an error unless it would happen to be cut off at a valid boundary for both gzip and tar. Whether that is likely to exist depends on how the tgz was created.

[root@(none) shm]# tar cfz Test.tgz /usr/local/Kobo/

I've past this discussion on to Kobo and will see what they say.

Thank you for the clarification! I was not aware of this difference between the busybox version and the real thing.

I was reading earlier today and I noticed that there was a word hyphenated on the first line of the first paragraph of the chapter. Does this mean that the bug of not having a hyphen in the first line of a paragraph is now fixed?

This is with firmware 3.12.0.

[famile-dinner]

Hi;

I'm new to this forum and am having an issue with the new 3.12.0 software and Kobo's customer support has not been helpful.

It seems like the "Refresh every: Chapter" option makes the screen go black between pages with every page turned forward or backward. The "10", "5" and "1" page options work 'properly', but I'd rather have it refresh every chapter, obviously.

Has anyone noticed this? Is this a bug or is this something you all know how to fix?

thanks

Same story here. I bought the Aura specifically for the "refresh every chapter" option as the refreshes on e-ink readers make me dizzy. It worked at first and now mine operates exactly like yours. I've notified Kobo who tells me the problem has been "elevated" and is "being worked on". About a week ago they told me it would probably be fixed in about "48 hours" and I should be able to update at that point and it would be fine. NOT. If this doesn't get fixed, I need to return the Kobo.

I have patched my H2O and I have it set for every 12 pages and it works very well like that.

[StefB]

My Aura can be set for every 10 pages, but I want it to refresh every chapter as advertised. That is THE feature that determined my purchase. If it is every chapter, I can anticipate the refresh and avoid looking at the device. E-reader refreshes make me DIZZY.

Front line customer service doesn't have an actual clue about most things. If this is a firmware issue there is no way it's going to be fixed in 48 hours. While it's obviously a significant bug I'd be very surprised if it got fixed before the next firmware update which is likely a month or two away because it's not a showstopper bug (i.e. preventing most people from reading on the device).
If you scrounge around in the forum it is relatively easy (just a line to add in the config file maybe?) to set the device to only refresh every xx pages (up to once every 99 pages). May not be a perfect solution, but if you really like the device otherwise it might get you through until it gets fixed.
EDIT: sorry, just realized you wanted end of chapter so you can anticipate it so this solution likely isn't going to help.

[StefB]

Thank you. I wish I knew what "just a line to add in the config file" means!

Is there a way to revert to the previous firmware? I've been reading here for an hour, and I gather that would be 3.11.0.

Thanks again.

[JSWolf]

Current firmware 3.12.0.
Previous firmware 3.11.0

[StefB]

Great, so if I'm having a problem with 3.12.0 and want to revert to 3.11.0, how do I do that?

Go to the following thread, find your version of the 3.11.0 firmware, download it and read the thread. It will tell you how side load the firmware.
