Is serial jailbreak possible on KT4?

Hello, I have a KT4 updated to 5.12.2, so my only option would be the serial jailbreak. Somewhere I've read that for KT3 and KT4 is not possible, somewhere else that it is. Could someone shed light on it? Thanks

Point to that "somewhere else" so we can flog them with kindling .

(Snark aside, that'd be a no, as far as we know: Androidized partition layout, hardened boot process == HFGL).

damn, so no way
I've read in a chinese blog (translated by google) and also into some replyes here, but indeed they didn't do on a KT3 or KT4, they just put these models into the models possible of serial jailbreak...

@NuLuJe: Perhaps we should collect a list of models in the Open Sesame thread of the "Androidized" models. This topic has come up several times recently.
I only have a few of the models since I quit collecting Kindle models some time ago. I think that I only have two or three of the "Androidized" models.
It will have to be for the members here to provide the information.

@knc1: That's basically KT3+, right? i.e., anything that was originally shipped on >= 5.8.x (KT3, KOA2, PW4, KT4, KOA3).

The "final" "friendlier" model being the KOA.

Or did the KOA2 slip through the cracks? (I seem to recall those being hard to open without killing 'em, anyway...).

TL;DR: In which case, yeah, I can point that out that when the serial approach is mentioned, good point .

I think KOA2 is androidized. It certainly exports /mnt/us weirdly and misbehaves toggling USBnetworking.

I have seen no reports of opening KOA2 without destroying it.

I do have a KOA2, it is jail broken, but I do not recall what all I might have done with/to it.
I am pretty sure it is "Androidized".

Another exploit lost to the sands of time then.. ?


On a more serious note, there is a lot of android development /hacking expertise over at xda-developers for anyone who might run into a brick wall with androidized models.

The problem is that you make the jailbreaks public and that means that Labs26 can then fix what exploit(s) were used.

Not so much, we had/have support for the KOA2 and mine is still running 5.9.x


You can read through the documentation on the SoC's on-board "secure cpu" features here:
https://www.nxp.com/search?category=...siblings=false


NXP is the previous owner of Freescale
Freescale was the previous owner of Motorola
+/- varies split ups and joins over the years.
But IIRC, Motorola was the purchaser of ARM (Arm inc. IIRC).
