1) Thanks a lot to all the people that keep working on jailbreaks, KUAL, Koreader etc.
2) Recently purchased Paperwhites from Amazon.de came
with 5.10.3
firmware (8GB version, G000 PP12) and
8437 (10/27/2018) 5.10.0.2
firmware (32GB version, G000 T6)
3) After creating "update.bin.tmp.partial" folder I tried installing jailbreak thinking that factory sealed unregistered unconnected to WiFi PW should have "factory image" installed. Well it ain't so. !installHtml did nothing.
I'm posting this just in case somebody assumes the same and fails too.
After installing 5.10.0.2 factory image linked in the first post everything went without problems. Jailbreak, Hotfix, MRinstaller, Kual etc.
And now I have questions.
It should now be safe to install customer 5.10.1.3 firmware, turn WiFi on and connect it to my Kindle account. And reinstall whatever is lost during update. Right?
And in case I ever need to Reset it, it should revert to 5.10.0.2 (factory).
And 2nd question:
Can somebody please link a thread where the difference between factory image and customer firmware is explained? Search returnes a lot of jailbreak related posts but I could not find the explanation.
I see 5 versions of 5.10.0.2 and 4 versions of 5.10.1.3 mentioned, but don't they all live above the same related base factory version?
Thanks for answers.
