Hi - I hope someone can point me in the right direction. My Kindle Touch is on FW 5.3.7 (with 1,800 MB free) and is never connected to wifi. Ages ago I installed Jailbreak (from this file update_jailbreak_bridge_1.7.N_install.bin) and Kindlet Jailbreak (from this file update_kindlet-jailbreak-20121029_install.bin). Since then the "collection manager" and the "cover of the last book screensaver" had been working perfectly. Until.... a few days back, the Kindle crashed: on pressing the power off button, I got a completely blank screen and no response from the power button. I got it going again by holding the power button in for a minute, when the Kindle rebooted (I think, not sure, it started again anyway).
Since the crash, the cover of the book I was reading at the time always appears as the screensaver now. Changing books, and allowing the Kindle time to shut itself down, didn't make the cover of the current book show. At the time of the crash, I had Python version either 0.6 or 0.7 (sorry, I no longer know which) installed and screensaver 0.14 (from this file update_linkss_0.14.N_install.bin). They would have been installed from the links in post #1 of this thread back then.
Opening a book I had previously read with a known good structure and cover image made no difference. The cover at the time of the crash continued to show as the screensaver.
I have now installed Python 0.14, updated, installed linkss 0.24 and updated again. The install files were downloaded from the links in post #1 a couple of days ago. And still no change - that same cover remains showing. I also dropped a "pinfo" file into the linkss folder to see if any personal info would appear - but nothing changed, still the same book cover.
There were 221 items in the cover cache folder. The folders 'discarded', 'overflow' and 'staging' were all empty. I deleted nearly all the cached covers and tried again. Still the same book cover appears. And following the advice in the Q&As at the top of the thread, I tried to set the date and time on the Kindle Touch, but it seems I can set only the time; date must come from wifi. The time is right but I've no idea what date the Kindle thinks it is today!
Next I deleted all the .png files in the cover cache folder. The Kindle didn't like that: choosing a book, page turning, "go to" function all work OK; but press the power button to switch off and nothing happened except for the screen blanking momentarily and then returning to the current display. The Kindle doesn't turn itself off automatically now.
Any suggestions on where I should go next to get the Kindle working properly again, and the current cover showing again?
Update: I reinstalled the file "Update_linkss_0.24.N_install_touch_pw.bin", updated the Kindle and now have access to power off once more. But the screensaver has changed to showing this text: "The ScreenSavers Hack is currently in 'cover' mode, but hasn't yet successfully processed a book cover
" I have also reinstalled Python, with no improvement. Changing books doesn't change the screensaver, but at least it's no longer the cover of the book I was reading when I had the Kindle crash!
