I pre-ordered this Kobo H2O when it was just announced. Barely after two years, it becomes more and more unstable.
1. Initially I noticed when I turned to next page, it turned back multiple pages. 2. The power on becomes harder and harder. In the last month, I used the pin-hole to reset more than I did in previous two years.
3. Yesterday when I was reading it stuck. I tried to reset. The screen flicks, and showing small squares progression bar. It stuck at the first square.
4. I reset again, it restarts and stuck at 2nd square.
5. I reset again, it restarts and stuck at 3nd square.
6. I tried a manual factory reset, it shows a white screen and no display whatsoever. When I power it on, the little LED beside the power button went on. The LED beside the power button stays on until I hold the power button for about 13 seconds. The screen no longer flicks on / off. After I took the device apart, it shows two black marks (see attached photo). Does the screen broke?
7. The device was charged but it didn't help.

After reading a few posts, I suspect the SD card is corrupted. I downloaded the USB Image Tool and scanned the surface, all sectors are good. But I still suspect that the file system corrupted. Could anyone send me a SD image for trying on a different SD card? Thanks.
