obviously lg can release jb for o4x now.

[LG Optimus 4X HD] skydev:
Alright, thanks for the files.

Extracting ~40mb file wielded cab file with no traces of headers.

The only thing i may be afraid of is of reverse-direction-ecb (or e-c-something) encryption of kdz files.

I hope that those files will give or completely different or similar results - then reversing will be required.
[LG Optimus 4X HD] DeeJay1:
Let's say...

let's say I wanna be "stupid" and decide to flash this "incomplete" kdz file, the 489mb one...what's the worst that could happen to my phone? Lol, just curious that's all
[LG Optimus 4X HD] morenosorina:
Lg italy on facebook doesn't know a date for the release of jb on lg 4x ..what a..
[LG Optimus 4X HD] skydev:
I am not sure about kdz encryption algorithm.

Flashing seems to be multi-step-process: first bootloader is flashed, then system (kernel, rom) and data.

Possibilities are:

File / encryption has reverse ordering: kdz file will be rejected.

Kdz structure / sig is checked: kdz file will be rejected.

Most probable situation (if flashing will occur for some time, then fail): part will be flashed, part will be not.

The best of that, is that with probability of 99% in that situation bootloader will be flashed, and it will be possible to unlock it, and flash any O/S you want.

Of course that all is my thinking, and i am not really sure what will happen. Although, hope for the best, but dont want to risk.

The probability of trashing bootloader (That it will be on boundary of cut archive) is very very low.

[LG Optimus 4X HD] DeeJay1:
Thanks for your reply. You may be right, but I'm guessing it just would fail to flash...BUT I'm not going to risk it. And if it indeed flashes part of the file, like kernel and bootloader, wouldn't that brick the phone since it wasn't meant to be for ICS?

I asked LG Hellas and they replied that they don't know when it will be released.

Of course I didn't expect any numbers or clear response.Also I don't understand why the announcement of a time period must have a reference only to the end of it ...say Q1 and for once surprise us and release it at the beginning ...Just one time!!

[LG Optimus 4X HD] skydev:
Not sure about it, but, for example, bootloader of my Nexus 7 seems to be reverse-compatible: when i flashed 3.x version of it, instead of stock 2.x, it indeed allows to boot older version of O/S.

So, I think, that it should be reverse-compatible. And anyway, if recovery will be intact it should be possible to recover the phone.
[LG Optimus 4X HD] iceddeath:
and what is the point on telling that in this thread. this thread is not about choices between LG and the others. just go away then
[LG Optimus 4X HD] DeeJay1:
Yes that's exactly what I was thinking. As long as I can get to the software upgrade mode on the phone I should be fine, just flash back to 10H....so tempting lol
[LG Optimus 4X HD] vrmanzacky:
Re: Official JB discussion Thread

why this people always post something useless, you can sell your phone with other device, just compare when 4x has UNLOCK BOOTLOADER and custom kernel With yyour new device
[LG Optimus 4X HD] Atomix86:
As long as the bootloader successfully flashes then you will have access to the built in LG SW update feature so you can go back to v10H. If it doesn't however... :crying:
[LG Optimus 4X HD] DeeJay1:
Lol that's what I fear...
[LG Optimus 4X HD] @non4:
Re: Official JB discussion Thread

And even if it does how would you know how to unlock?

Sent from my LG-P880
[LG Optimus 4X HD] skydev:
Well, there are 3 possibilities.

1) Bootloader is in tail, and is not flashed at all -> bootloader kept intact -> recovery possible

2) Bootloader is in head, and is flashed -> bootloader integrity ok -> recovery possible

3) Bootloader is at ~489 MB of file -> bricked

Size of bootloader is approx 1-2 MB

Probability of bootloader being at excactly that point of file is approximately 0.0001 - thats 0.01%
[LG Optimus 4X HD] Atomix86:
Because I can. And it seems people agree with me. "just go away then" isn't exactly going to scare me off, so if you have nothing productive to add, I would appreciate you not quoting my post :) .

I imagine it will be similar to the HTC One X, which is fantastic, however you must realise that there are only really 2 devs in the 4X HD section and even if the bootloader gets unlocked this side of Christmas, it will still take time to create and compile an optimised kernel, it's not like Jellybean will get released by LG then within 30 minutes a super-kernel will appear ;) .

---------- Post added at 06:59 PM ---------- Previous post was at 06:56 PM ----------

Exactly, if he flashes correctly, he will still have a soft bricked 4X HD witha JB bootloader on it, nothing more :P .

Well said, I honestly think flashing just to see if bootloader will work is not worth it, it's not like it will allow flashing of anything new atm.
[LG Optimus 4X HD] DeeJay1:
I don't need to know how to unlock it. As long as I take the leap of faith and can confirm that it is ok to flash it, dexter, kholk or whoever can get the ball rolling and unlock it...or we just wait for LG to deliver on their promise lol either or
[LG Optimus 4X HD] skydev:
Probability of it not flashing at all is 99%.

And probability of me finding bootloader is nearly 0.1%

I decrypted 40mb file and 460mb files with LG Tool with added decryption menu items.

Bytes in head are entirely different. It seems, that the kdz file is reversed or something. Or it needs to be padded to the correct size for decryption.

Or that may not help, if decryption is backward-going and chained.

You can try flashing, i almost certainly can say that it will say, that kdz is invalid.
[LG Optimus 4X HD] iceddeath:
yes you can. but off topic.

and who said i want to scare you off.

also, i have nothing productive to add, tell me more about how productive you are on that post by saying this :

"Already decided never to get another LG. From now on its HTC, Samsung or Sony."

SO PRODUCTIVE! SALUTE! The most productive official JB discussion of Optimus 4x HD post ever!
[LG Optimus 4X HD] Atomix86:
If it unlocks simply by flashing, then I guess technically they could make a perfect version of an AOSP rom, assuming of course the JB kernel is safely flashed too, and then yes, technically we could flash that "perfect" rom over the dirty kdz flash, but it's a bit iffy at best.
[LG Optimus 4X HD] DeeJay1:
Exactly. But hey patience is a virtue! So no rush

[LG Optimus 4X HD] kaisersosay:
assumptions and presumptions

A lot of wild guesses flying about and here is my guess ( hmm suggestion if lg are reading ). A bird in the hand is worth two in the bush i believe the quote. How about the previous mentioned leak or whatever you want to call it is actually a near final version and lg will release it in the next 6 hours including their few little bugs because no one would mind. ( please ) In reference to my earlier quote a more apt translation could be, a test version on the phone is worth two finalised versions on an encrypted lg server.
[LG Optimus 4X HD] skydev:
Alright!!! I padded file with zeroes to correct size, and got correct header of the cab file!

Now i can progress with my task.
