JailBreak (4.0.x - 4.1.2)

[Kalja]

I saw it after I did an manual reset because of frozen screen in the diags menu...well I just try the whole procedure again...

@Kalja: Where did the hard-reboot lead? diags or main?

[Kalja]

Diags...

[NiLuJe]

@Kalja: Hmm... Some logs would definitely help .

[Kalja]

Sorry - can't find any logs - just this file:
DiagDisableTest_1.0.6.210_B023170123560K01@0.gz

Is it possible to try the Jailbreak again?

(And, yes, it should be safe to run it again).

2nd run:
Everything works fine until the Reboot procedure described above - ecreen freezes and only manual reboot works. During reboot screen with "Your kindle will be freed" or so is shown - back to the diagnosis - then wanted to exit - doesn't work, missing: "deviceSettingInfo.xml" although it is there...back to the diags...reboot - kindle starts normal...no jailbreak...regarding the logs I don't know which "search bar" you mean - the one within the normal kindle mode? No logs were created with the commands maybe I am too stupid...

@Kalja:

* Like I said, I'm (fairly) sure the lack of feedback on screen is normal during the reboot. If the K4 is anything like the K3, it's known to take forever to boot.
* Yep, probably because of the hard-reboot that it's whining about the xml file (unless you forgot to upload the folder).

* And, yep, on main, the usual search bar in the home screen. It's three separate commands.

One other thing that you could try, is to skip step 3) & 4) (ie. reboot directly to main after the first boot to diags).

So, I tried every possible method - JB didn't work - so I wait until another user was more successful - anyway thank's a lot NiLuJe for your help!

@Kalja: I have a fairly good inkling of what the issue might be, but I really *need* those logs to confirm it...

[Kalja]

Believe me I would give them to you immediately but no logs are created with these commands - sorry

Home Screen - Menu - Search - Enter ";debugOn" ,confirm the enter: ";dumpMessages", confirm then enter: ";debugOff" confirm - result: no logs created within any folder...

@Kalja: Check if things go better with v1.3.N (just posted).

I acted on my suppositions, let's see if I was right the good old way: by trying!

[Kalja]

Ok - once again...be back in a minute

Just to clarify - it is OK to creaty an empty "deviceSettingInfo.xml" within the doc log folder? Or was that my mistake???

[Kalja]

I don't know what you changed BUT....FINALLY...EVERYTHING WORKED...now I look at my Kindle with new screensavers...thanks a lot for your help!!!

@Kalja: w00t! Thanks for sticking with me, and your quick responses .

TL;DR for those interested: trying to detect the Kindle version from the buildnumber in version.txt is starting to become a highly inaccurate science. (The fact that I used stricter version checking than Yifan's original script didn't help...).
