Sickel rebooted my Glo more often in the hour after updating to 3.17.0 than I have had occasions to use the pinhole reset in the almost-three-years that I have owned the device. I think the basic problem is that it is quite normal for the device to be slow to respond soon after booting, as the database will not yet have been loaded into memory and so all queries wil be slow until that happens. It quickly speeds up once the commonly-accessed tables are cached in memory, but when sickel reboots because of the slow first access that doesn't have a chance to happen.

But now with sickel patched to wait 30 seconds instead of 10 seconds before pulling the reboot trigger there have been no more issues. So far this firmware seems to be a small but good improvement on 3.16.0, the PNG bug is fixed, and the screen now refreshes after opening a book to clear away the ghosts of the homescreen tiles.

Edit: The heavy ghosting in menus and popups that started in 3.15.0 hasn't been fixed, but that is not a big issue for me so long as it doesn't affect reading.
