Hi,

I am having a similar issue as the author of this thread. I have a Kobo Aura First Edition. Bought it in 2014. Had been using it on and off until about 6 months ago. It has been sitting on the shelf since then.
Now I have the infamous "Please charge your ebook" screen. Then I read a lot on mobileread and left it on charge for like 5 hours. Tried all the reset methods (hard, soft etc) no go.

Opened the case took out the battery and measured the voltage on it. It read 3.7 then I left it on charge an hour more and the battery read 3.75 this time. Finally I left it overnight now the battery reads 4V! I guess it should not be the battery.

When I switch it on the orange power led blinks bright and after 7 sec or so dims a bit for like 3 sec and stops. During this time no usb connection or even serial connection is possible. Serial port vcc reads 5V for 2 sec and goes down to zero.

Since this model has no removable SD card I cannot reflash a fresh firmware either.

Ran out of ideas here.

Any other suggestions are greatly appreciated!
Thank you.
