Little OT:

I've just seen infos about LG L7 II Dual, when i read about Jelly Bean in it (only 2x1.0 dual core) i was like ====> : O

It seems like that LG finally started doing good job :D Just take a look for another manufactures too, HTC is still releasing ICS updates (Thunderbolt), Samsung had forgotten about Ace2 etc, but LG now has only one phone (older 3D, and i meant phones with dualcore+, older LG phones are way to old) without ICS update, or i didn't see anything about the update

And about last topic: i think 18abc and d alphas are enough from 18's, now there will be 19's betas... or?
[LG Optimus 4X HD] iceddeath:
let's hope with the many alpha tests.. it will be a sexy beast! smoother device, more beautiful interface, better camera, better battery life, usb otg! :victory:
[LG Optimus 4X HD] hutjeflut:
i still silently hope LG is completely blowing people away by ignoring 4.1.2 and releasing 4.2 instead for the 4x hd.

this will a be a great deal for LG as that would make them the first with 4.2 (apart from the nexuses) and even if they do it in march people would easely accept it being later then the rest if they gor 4.2 instead of the 4.1 that they are expecting.

so hancing out 4.2 would be a great marketing move for LG.

als what happened to google making it easyer to do major firmware upgrades?

its still taking just as long as it used to google should really find a way to install updates without affecting the custum ui of the manufacturers so they can be released within a month (just some linking to ew features needs to be done then).
[LG Optimus 4X HD] Dexter_nlb:
you do not need to be silent, LG will not release any 4.2.1 unless they test it, and no indications show they have, only new 4.1.2 releases.

so you LG will just suck badly at being first on the front, they always will be behind on their own proprietary devices.

when you get 4.1.2 next month you will feel even worse, and still do it silently :)
[LG Optimus 4X HD] hutjeflut:
im not even on the front line to install 4.1.2 hehe i want to see how it affects battery and free memory first.

i have less then 1% battery drain overnight now and on average 500mb free ram.

all these new for me useless features might soak up ram and fored fs rendering might kill battery as it costs more computing power.

so ill wait and see.

i just hope lg would pull a stund like that because its good for the company.

i feel that they make one of the best phones do it for less money but 1 phone in there past (2x speed) keeps hounting there reputation unfairy. HTS and specialy samsung also have a bad history on firmware updates but they dont get punished for it like LG is which buggs me as there products are quite nice now if not the best.

so releasing a 4.2 would ahve made people jealoud that lg is the first and that would be a major deal for there reputation.

lets face it there is no proper reason the S3 sells as good as it does as its not even a LOAD better and on some points its even worse.

its all about reputation these days and lg needs to fix that.

and why would we feel even worse when we get 4.1.2 next month?

all it does is proof a whole lot of people how wrong they where.

they all left the 4x hd as they where so sure it never got updated if it gets updated they where wrong thats just icing o my cake.

personaly i dont care about firmware updates unless they are a major plus and as said theres no reason to believe the 4.1.2 or 4.2 update bring a preformance boost (which we dont even need i even disabled 2 cores :P) or saves battery wiich is unlikely as all the draining comes from using the phone.
[LG Optimus 4X HD] pierg75:
Re: [UNLOCK SOON!] Bootloader unlock bounty

Tbh I'd not be so happy about 4.2.

I have it on the nexus 7 and it doesn't really work so well.

4.1 is much snappier and fluid and I don't see any major improvement in 4.2 vs 4.1.
[LG Optimus 4X HD] Dexter_nlb:
this tells users more about them using it, than the operating system. battery drain and memory free does not really relate to speed or increased use of battery. or getting a new update and seeing that you feel its worse or better.

didnt you just point out alot of fact and being hesitent? i guess you are pretty good and making up your own reviews and decisions on if any update works or not. so keep the phone you got for 5 more years , it will suit you best.

point was LG decide finally to get 4.1.2 out on this model, when they got other models doing 4.2.1 just fine. so dissappointmont is LG's business currently and other companies dealing with google.

[LG Optimus 4X HD] hutjeflut:
i personaly am not to enthusiactic about 4.1 indeed but most people have bin crying for it since the day google released it.

as for the speed of lg's major firmware releases yes tey are slow but i do get the feeling they spend a lot more time testing then the other brands.

and it shows as the 4x hd rom simply will not crash and it feels smoother then both the one x and the S3's interface.

seeing smoothness is 4.1's biggest selling point and the LG being as smooth as it can be i cant see a benifit.

as for lg finaly deciding to get 4.1 for this phone is a bit wrong.

first of the phone isnt even a year old and jb wasnt released by google untill 27th of june and so its not all that bad so far as people make it sound.

they just speem to take a long time testing there roms.

and personaly id rather have them take 3 months extra time and make a flawless supersmooth rom then rush it and have loads of flaws in the rom.

sadly most people dont seem to think that way.

ah well all we can do is wait and see if 4.1 is a do or dont.

im pretty happy so far apart from the fact i do have to root it because i want to clockdown the cpu as 2x 1500 mhz is still to fast for most apps (have 2 cores disabled with quadgearbox).

and less strain on the battery is never a bad thing.
[LG Optimus 4X HD] Dexter_nlb:
Remember or did you read any of Nvidia announcements? a quad core cpu having all 4 cors active, use less battery than having less core processing.

see it as if you machine is push for 4 cpu's you got 2 enabled, the 2 cpus will process at 100% and use much more power, than 4 cores using less, like mediascanning or media playback, where 4 cores use only 25% each, which means less power and battery usage.

you might see visually that it looks better, but Nvidia would like to prove you wrong on that statement, thats some engineers you have to deal with, if the intentions are to have all 4 enabled.
[LG Optimus 4X HD] hutjeflut:
yeah that seems logical.

but my main concern and reason for downclocking is seeing some apps like browsers and movieplayers using all 5 cores on max power which is a complete and total waste as 1x 1200mhz is more then enough for browsing and HD playing yet it seems to be using 4 cores on 1500 mhz for some reason.

in optimized apps the workload spreading seems to work pretty great.

most apps dont even reach the 600 mhz barrier.

its those few apps that seem to drasticly drain the battery.

ive not tested average use myself but im now building battery statistics on % used er app with better battery stats on the 2 cores. maby in a week or so when i have proper data (over 10 hours per app) ill enable the 2 cores again and bould statistics with all 4 cores sand then compare drainage per hour for 2 or 4 cores.

takes a while but well figure out the best way.

right now im just trying to expend the battery in lots of ways while active.

idle the battery is amazing and with permanent wifi on i think 7 days standby is easely doable but under load you literaly see the battery drop 1% per 2 min.

anyway ill let you know my findings in a while hehe.

maby ill just buy those 2680 mah batterys on ebay should give me another 45 minutes play time :P

a small edit :

look at this movie of nvidia to explain the cores and you will see that its not equalling out load but just moves to the next core if the others can no longer handle the load.

https://www.youtube.com/watch?v=4dZsS-C6f2Q

which brings me back to thinking that 2 cores disabled (if you dont game) is the way to go as they are the first 2 to be loaded anyway and you will never use power of the 2 cores you dont need anyway.

m.a.Garcia has it, kholk already tried with him to get the BL, but they didn't do nothing.. :(

At leaat they could check the compiled kernel

@down sorry for misunderstanding, i forgot what i had read in SBK thread..
[LG Optimus 4X HD] Dexter_nlb:
common misunderstanding for users, that bootloader being unlocked, does not mean that flashing a bootloader from an unlocked device will help, that is pointless, since we got the same bootloader as developers BUT the device is locked.

so dumping the bootloader of a developerphone from a tegra3 device do not help anyone to understand it any better than what wdpark already did for us, when he distributed the unencrypted BCT and eboot partitions, but those cannot be used before the chipset knows we got our device unlocked so basically thats why wdpark did get much further i guess, since the SBK (SecureBootKey) is placed in the hardware and that is where the hacker or cracking was needed.

so basically a developer phone, is a unlocked device, not a unlocked bootloader, this is based on facts that they can use most of the kdz trick to install new updates using the parts which are not encrypted, as the kdz seems to hold encrypted and clear code.
[LG Optimus 4X HD] brunomars:
I will try soon with .kdz method. Extract the boot.img in the kdz and then getting the Ramdisk and unlocks the bootloader then VOILA!

Will try asap
[LG Optimus 4X HD] Dexter_nlb:
sounds like a good challenge :fingers-crossed: , but thats all it is :confused:

we got boot.img and recovery.img already. otherwise a clockworkmod would not have existed :angel:
[LG Optimus 4X HD] kholk:
@brunomars

Your "getting the ramdisk unlocks the bootloader" statement is just more than simply unbelievable.

The boot.img signature is being checked by the bootloader prior executing it, and the current bootloader will check/not check for signatures only if odm_production is 0, therefore we actually need to flash a new bootloader that will disable signature checking in other ways.

@Dexter_nlb

This is actually incorrect.

Unlocking the bootloader doesn't mean having access to nVFlash... see how it's done on the One X: you've got access to Fastboot through HBOOT (their bootloader) and the signature check is being turned on or off when the bootloader gets locked or unlocked.

A way for LG to implement a "bootloader unlock" would be, if they don't want to implement the fastboot interface, to simply give to the user a way to disable the signature check, perhaps reading the status from a reserved partition or anything like that.

What I said invalidates what you said, basically.

About getting the bootloader, well, everything that contains a valid signature can be executed, therefore everything containing a valid signature can be flashed without problems.

Ah, another thing: that user's device is a retail device, not a developer phone. I'm not an idiot, you know?

Especially after years on Motorola ;)
[LG Optimus 4X HD] brunomars:
Re: [UNLOCK SOON!] Bootloader unlock bounty

Well. Your the boss. Man, i did it. But failed. Like what you said. D AM N
[LG Optimus 4X HD] Dexter_nlb:
and EBT/bootloader is checked by the chipset having a valid sig, so you bascially need to be able to sign that new bootloader with a LG signature :) so thats double up on getting it to work based on brunomars's goal.

of course it is, i did not mention nvflash at all.

You refer to the N7 being OEM unlocked i think, where bits on a partition enable/disable OEM locking.

I believe you are in agreement stating bits and bytes somewhere could determine if boot/recovery is locked. i believe my statement

since we got the same bootloader as developers BUT the device is locked - is accurate.

My reference to unlocking bootloader, was the failed attempt to open bootloader, which needed more than a unencrypted bootloader with sigchecks disabled. That was my statement and i believe i am still correct on that one, when i say, you need more than a bootloader(from dev phone) to make it work seen from xda users point of view.

Re: [UNLOCK SOON!] Bootloader unlock bounty

A nice explanation of terms (and security measures) can be found here:

http://goo.gl/T0sqN
[LG Optimus 4X HD] ReMiXxXeD:
AW: [UNLOCK SOON!] Bootloader unlock bounty

Haha ! I Dont understand anything !:DD
[LG Optimus 4X HD] kholk:
I wasn't referring to the N7, sincerely.

The same bootloader can act differently on retail or eng/dev phones as I already said in my previous post, depending from the odm_production_mode fuse (burnt/not burnt).

About needing more than a bootloader from a developer/engineering device, that's exactly what I said in my previous post, too.

Perhaps, we're misunderstanding each other and I think it's necessary to summarize what I said:

1. Same bootloader can act differently on two devices, dependant on the state of the SBK or odm_production (programmed / not programmed)

2. As N.1 is true, we'd need a new version of the bootloader that will manage the "locking state" differently from that (as an example, reading it from a partition)

3. As N.1 is true, it's an error to associate a dev phone to totally unsigned binaries (those can contain signed retail binaries, why not!)

4. The bootloader I tried to dump is anyway a retail BL and SIGNED, but without taking it from that V18c phone I can't disassemble it to verify if it contains a way to "unlock" or not.

That's pretty much what I said.

P.S.: The bootchain is: BootROM -> Signature check (in BootROM) -> Execute (the bootloader) if computed hash = expected hash
[LG Optimus 4X HD] Dexter_nlb:
just to say: fully agree, just misunderstood. i explained this differently.

your single qoute says it all, bootloader sig check makes all the difference. and builtin sbk makes the same bootloader act differently on dev or retail . which is what i meant too, but included bootloader sigcheck as another part to workaround.
[LG Optimus 4X HD] kholk:
hahahaha!

Actually, I don't think LG will be so good to give us the SBK to use nVFlash, so in any case, with a new "unlockable" bootloader we would skip another signature check and not the one in the BootROM.

I could continue that chain with:

Bootloader(LG) Execution -> Signature check (RSA this time) -> Execute boot.img/recovery.img

We would disable the second signature check, as anyway the bootchain will be secure.

It would anyway be like a dream to have the unlock via access to the SBK, as the device would then become like an engineering board. That would be wonderful and really really really funny for the real developers.. as repartitioning (that can be done only if we have access to nVFlash) has got no price at all :D

Oh and to be precise, the state that will make the bootloader to turn ON the security checks isn't about SBK being programmed or not.

It's just about the odm_production fuse: you can have an SBK on your device, but if odm_production is 0, the security will still be off ;)
[LG Optimus 4X HD] Dexter_nlb:
and that i admit i mixed up, as i did imagine SBK always to be in effect if installed/found.

this makes me wonder, how bootloader or unencrypted bootloader edition gets selected, so that fuse makes it possible to boot all unencrypted, since device seems to have both installed according to what wdpark extracted early on from kdz files.

---------- Post added at 02:01 PM ---------- Previous post was at 01:54 PM ----------

on another topic of unlocking our bootloader, i believe we lose the DRM support on the rom when it is done.

this will mean that DRM functions will be disabled for some apps and cyanogen do not have working DRM licenses anyways.

which is similar to the unlocking on asus, where those keys are cleared when the unlocked mechanism is touched.

but i think the users of DRM affected content and maybe netflix too (since the stream is DRM encrypted), are alot less than those using the rom for legit DRM based business.

DRM might work on cyanogen on some mobiles, i do not say is does not, but then i suppose license restrictions are broken, but no one cares much.

on this LG mobile, it might be different and something breaks when it gets unlocked, unless we can restore , unofficially, the drm license :) again, not a legit act i think.

that might be why they protect the DRM so much in this release. since its a delicate matter to open a release of, and source cannot be provided with their keys.
