Evening all.
Before I throw my Gen3 in the bin and buy a Kindle, I was wondering if anyone had any suggestions please on how to make it work again.

It's the old, slower version, with the latest Mobi firmware - 1.16.1197
Worked fine apart from one freeze every couple of months, till this morning when, after I had finished and deleted The Pretty Lady by Arnold Bennett in Mobi format, I tried to page through the other books on there (about 180, mostly old stuff from here or Gutenberg.)
Anyway, after paging through three pages of the book list, it brought up the second boot page - the one with three big dots and a small picture of the cybook. The green power light went out and all went quiet. after a minute or so, the green light flashed on, the same page with the three big dots flashed off and on again, all went quiet. It is now cycling through that screen every minute or so, flashing off, coming up with that screen and staying there till it flashes off and on again.
I don't use an SD card apart from upgrading firmware.

I have tried:
1. Deleting everything on the thing and reinstating all the files it came with when new including system files (I'd copied them before using it) - no change
2. Re-upgrading the firmware no change
3. Taking the battery out for a couple of minutes and replacing it -(usually works in my Android phone) no change.
4, Deleting everything and restoring all the files as they were a few months ago when I did the last backup - no change.

I can turn it off and stop the recycilng screen using the little hole at the back, but when I turn it on again, I get the usual Cybook Gen3 first screen, then the one with the three dots, and the recycling of the three dot screen starts again.

Before consigning it to the bin, I wondered if anyone knew anything I haven't tried that might work, or if anyone recognises those symptoms as fatal.

Thanks
