[Kobo Glo HD N437 - Unresponsive to Screen Touches when not plugged in or connected to WiFi]

I'm at a total loss.

Brand new Kobo Glo HD N437, ordered online from Aliexpress.

Works like a charm, apart from it becoming unresponsive to any screen touches UNLESS plugged in OR connected to WiFi. How weird is that? The screen touches are actually paused/delayed until either plugged in or conconnected to WiFi, and then all the touches come through at once. It's as if they get held until a trigger that frees up the movement again...

Tried both a soft and hard factory reset and an automatic online update to the latest firmware with my new kobo account, as well as changing every setting. No luck.

I'd love for this to not be a hardware issue. Maybe some useless file in the firmware or hidden directories just needs a little coding change or deletion?

I've searched everywhere online and have come up with nothing.

Please help us, Obi-Wan.
You're our only hope.

🙏🏻

Have you tried reimaging the internal SD? It could be the iMX CPU getting hung on something. (please note: I do not know if the Glo HD has an internal SD card like most models) Worth a try.

What does this mean? Honestly, I have no idea what you mean by these actions. I know what a "factory reset" is and how to do them in different ways on all my devices. But, I have no idea what the difference between "soft" and "hard" would be.

Well, I can think of a difference, but, as it something that was added in the 4.15.x firmware release, I don't think that is what you are talking about. Except by accident.

and an automatic online update to the latest firmware with my new kobo account, as well as changing every setting. No luck.

Did the device respond when not connected to the PC after the factory reset and before any setup was done? i.e. Could you chose how to do the setup without the USB connected? If it didn't respond, then it is probably a hardware problem.

If it did respond, then maybe it is software. In that case, I would suggest doing the setup using the PC and Kobo desktop application, but, before ejecting the device, remove the firmware update files and testing with the factory firmware. The files to remove are in the ".kobo" directory. The are the files "KoboRoot.tgz" and "manifest.md5sum" and the directory "upgrade".

Do the factory reset using these instructions: https://wiki.mobileread.com/wiki/Kob...ing_squares.22

I have not tried. I believe it has a removable SD card.

What does this mean?

That I've done a factory reset by selecting the options from the Kobo menu, as well as doing so with the pin.

It responds at all times if plugged in or connected to Wifi, so yes. Any set up can be chosen.

I wasn't able to locate the files you referred to.
Here's a screenshot of the directory:


I've just done another reset. No change.

The pinhole isn't used for a factory reset. All it does is force restart of the device. Doing a factory reset from the setting has change with the latest release. Before it wiped everything back to the out-of-factory state. Now, it doesn't wipe the root partition. To do that, you need to use the manual method I pointed to.

No, I meant after the factory reset and the setup is displayed, does the touch work when the device isn't plugged in?

The files I am referring to are put on the device as part of the firmware update process. If you do it WiFi, you won't see them as they are removed once the update is finished. If you do the setup using the Kobo desktop applicaiton, it will copy the files onto the device. You can remove them before ejecting to prevent the firmware update.
