Having some BAD problems on the two 3.19 firmwares.
What i have tried is this.
1, Updated from 3.18.0 to 3.19.5761 (with kobo prg) and had problems.
2, Did a factory reset, still had problems.
3, Applied 3.19.5761 again after the reset, no change as in problem still there.
4, Downgraded to 3.19.5613, same problem.
5, Downgraded to 3.18.0, worked fine as it did from the start.
6, Factory reset again and then immediately upgraded to 3.19.5761, same problem again.
7, Tried using the patch (that i never even tried before so not what was/is the problem), same problem's again.
8, Down to 3.18.0 again (after i undid the patch on 3.19) which works fine again.
The problem i have is two different problems.
1, is that whatever file i try to open pdf/txt/epub/kepub/mobi and a couple of others the first time i "open" the file it opens to a blank page and only shows the title nothing else.
And after that i can do nothing have tried clicking/tapping everywhere and waited for minutes absolutely nothing happens.
If i press the powerbutton and set the kobo to sleep and wake it up again i can tap and gets the menu and can go back to library/etc and then i can open the same file again and it works fine (BUT only the same file).
And by fine i mean it works like it should and it works just as fast as on fw 3.18 to flip pages zoom/etc.
But if i close it and try ANY other file its a blank screen with title again and a sleep/wakeup makes that file work fine and no other files (including the one i tried before) works without sleep/wakeup.
It is the same for free books from kobo and imported files from calibre and i could put them on internal (with or whitout a sd card plugged in) or sd card (tried two sd card) with no difference at all webbrowser and games i did not even try.
2, The second problem is that if i do a restart with the reset/restart button besides the usb port it restarts fine and i can do things for about 10sek then the kobo is 100% locked up as in nothing happens when tapping/clicking power button backlight stays on for ever (i assume it did stay on for 3 hours while i did go shopping/ate/bashed my head against something hard in frustation).
Not even the reset/restart button does anything and connecting it to pc does nothing as in can not se it on pc at all.
The only thing that works is to hold power button down for about 30sek and it do restart but locks up really fast again.
IF i manage to connect the usb after it has booted to the kobo start screen (connect before that and the connect screen never shows up) and hit connect when that pops up but before it locks up (it is really close and took a few tries before timing it right) it do connect to the pc and moving files and so from the pc works fine (hence i could go back too 3.18).
The second time i upgraded to 3.19.5761 i played around longer then the first and the kobo worked ok and i could sleep and restart (as in more then sleep) with the power button fine and it "worked" fine besides the "blank screen issue" for every "new" file you opened.
And then tried pressing the reset/restart button and bam restart and then lock up.
After a factory reset it was back to working with the blank screen issue again and one click on the reset/restart button and lockups where back again.
After that i was done testing and went back to 3.18.
Have been reading for a couple of hours in the last 3 days after this and 3.18 works as it used to so i have a hard time believing it could be a hardware issue.
If it where a hardware issue some problem would probably have shown up by now right?
So anyone have any thoughts on what the h*?
