KPW2 5.4.2.1 available!

[fallenfuzz]

Hi All,

Just my 2c.
Installed latest version from amazon link, lost JB.
re-flashed latest sources and all good back again.

Thanks

@fallenfuzz: Are you sure you really meant to say lost the JB? I'd expect you to lose most of the hacks, but not the JB itself.

(ie. most hacks stop working, but you're still able to reinstall them without re-installing the JB itself).

I love you guys!!! Using "send to device" works perfectly, every cover has appeared as it should be!
Before that, I usually copy the ebooks directly to the kindle usb, within categorized folders, but still don't understand why it doesn't work .
Anyways, thank you guys! I really appreciate your help!

@MoVo: Because there's extra 'magic' involved (sideloading a thumbnail), which is done by Calibre's "Send To device" step .

Hm, didn't try that. But once I installed the update and tried to launch kual, it told that I don't have jailbreak so I went through JB + All-in-one KUAL prerequisites, flashed those two and all good now.

Ah, did it actually say that you:

That you do not have "the KINDLET jailbreak" ??

That would be expected.

It did say. yes.

[NiLuJe]

As knc1 said, yup, perfectly normal, there's a very good chance the *device* JB was fine .

Anyone had tried to install a PW1 firmware (e.g: 5.3.9) in a PW2 device ? Its possible ?

[NiLuJe]

@bnpssilva: Nope. Innards are much too different.

Not likely.
The two devices share a similar case and the "Kindle" name -
that is about as far as it goes.

[bnpssilva]

Are you sure?
Does anybody has even tried ?
I really prefer the firmware 5.3.9 from PW1.
This new firmware only look up for words in one dictionary. If it doesnt find it, dont even try in another.

Why don't YOU try if you disbelieve the developers here?

[bnpssilva]

I don't disbelieve in anybody, HarryT.
I just wanted to be sure because knc1 wrote "Not Likely".
You don't need to be harsh.
I didnt tried myself because if it bricks my pw, I wouldnt know what to do.

Thanks, NiLuje, Knc1.

OK, I will expand on those "it isn't going to happen" responses a bit.

The K5 models prior to the PW2 use a SoC from the Freescale i.MX50 series ;
The PW2 uses a SoC from the Freescale i.MX6 series.

One obvious "show stopper" is that the two SoC series use different GPUs - with a different instruction set.

Also, the SoC device (and its pin/signal relationships) are programmable.
That programing is not the same for an i.MX50 and an I.MX6 .

So a "brute force" - "just load a PW2 image file on a PW1" is **NOT** going to work.

Now back-porting a specific application feature (such as the dictionary service) **MIGHT** be possible, **IF** the system was openly documented.
But it is not.

My best advice - give up on this idea.
