JB worked great for me! thanx for the link

i flashed to JB using the link provided and it worked fine. quite laggy at first but settled down after a bit.

although i liked the feel of JB and some of the extra functions, i was disappointed to find that the upgrade did not add OTG functionality to the phone (having read that the JB update has added this function to other phones that did not originally support it; a HTC i think. i was optimistic it would for my 4x).

after playing with JB for a while, i've now reverted back to ICS (mainly to get my root back). but i'll be sure to put JB back on once the bootloader is unlocked and root is figured out.

cheers guys!

* update: apologies. after properly searching the forums i now have my 4x fully JB rooted (guess i should watch the forum rules video again) * :eek:
[LG Optimus 4X HD] hpnxfox:
Root for official JB is the same as for leaked version..look in my signature "All you need" link..i used it on my phone...and bootloader is also unlockable for euro open..

Factory Reset?

I was on v20A Euro open leaked version, when I installed that version I didn't made a factory reset, after the installation process JB recognize and "optimize" all the installed apps (on ICS) and voila, I have JB with all my apps working perfectly, I have a lot of apps configured and games in progress so install everything again scare me a lot.

Today I Installed V20A Euro Open official and everything happened again, official JB recognize and optimize everything, even the root apps works fine after I made the rooting process, the question is ¿do I really need to make a factory reset after official JB update?

Thanks.
[LG Optimus 4X HD] profyler:
yes, there is some few android services that update itselfs only after a Hard reset ...(example: OTA update service)
[LG Optimus 4X HD] Dutch Sephiroth:
Is there a difference between the factory reset through settings->backup&reset menu and the volume down + power button method?

(for after flashing official JB)
[LG Optimus 4X HD] ipred:
It's the same.

I have flashed jb from the day one of it's official release and it works great on my phone as i am not using stock launcher ( stock launcher has some redraws when it's creating an icon after a new installation of an app).With Nova launcher i don't have such a problem.Smoothness is better and camera is better.I only want an update of the nvidia drivers in the future.

Italy LGP880 AITA V20a 00_6 2013-04-08

Only listed 2day but actually it's available since 2 days

And I see l7 20a for L7 Euro open and alot of Euro countries announced 2day again dunno why
[LG Optimus 4X HD] gordonbennet:
Anyone know when it will be available in Australia? Cheers
[LG Optimus 4X HD] giurly:
I'm from Italy.

I've updated from v10h to v20a by LG PC Suite, no factory reset, still.

Everything works fine.

At night I switch off data & wi-fi, and with v10 the battery comes down of 2/3%

The first night after update it drains 30%! The second about 10%.

...wait and see or try factory reset?
[LG Optimus 4X HD] :
always good to do a factory reset after flashing different versions, and should be a must when crossing android versions.
[LG Optimus 4X HD] Insomniac535:
AFAIK the 4X was never released in Aus and therefore never was given an AU specific firmware. I'm in Australia and my 4X (Netherlands version) recieved the update as normal.

By the way, does everyone have the UI lag/stutter when an app is installing (not just downloading) via the Play store? I did a factory reset and then restored via LG's backup tool and I get the stutter. It seemed slightly present even before restoring but didnt test thouroughly.
[LG Optimus 4X HD] Jaydee239:
Well actually, my phone was working pretty well with JB without the factory reset but I did see multiple people advise to reset it, so I did. I hoped it would remove some of the animation that was added and stop the refreshing of my homescreen everytime i opened it. Other than that 20a was working well for me.

At first I couldn't get past the setup-user screen. It kept asking me to add a google account, even after I'd set up my primary google accounts. I fixed this by removing the LGPartnerSetup (or something like that) via ADB. Now, my "Home" button does not work. This is pretty annoying. I've resetted and cleared cache multple times.

I'm sure i'll manage to fix this; reflash 20a, try 20b or -worst case- revert to 10h (other suggestions welcome!), but this is an example where doing a factory reset did not do any good.

Support

i just talked to the lg support here in germany ... some news which are probabely interesting for us

- they know about the different software versions (262/XXX), but they dont know why (?!?)

- all devices are unlockable (also 262), but they wont tell us how

- they dont know if they can fix the 262/XXX problem
[LG Optimus 4X HD] leolipop:
Τhe L9 is getting a V20c version...so perhaps we could get a "C" version with qslide (or not) and finally unlocked (?) .
[LG Optimus 4X HD] BigBoyPL:
Qslide is add for "L Series". Why LG should fit it to other phones ?
[LG Optimus 4X HD] leolipop:
Why G has it then ? IS our phone so different or unable to run , why is the framework installed in JB ? Why do we all have smartshare ?
[LG Optimus 4X HD] RuedasLocas:
... 262-xxx...

.dz from Euro_Open is named: "LGP880AT-00-V20a-262-000-MAR-26-2013+0"

"all devices are unlockable (also 262)" and "they don't know if they can fix the 262/XXX problem"???

If its unlockable there's no problem, if there's a problem it's not unlockable... Where do we stay at? :eek:
[LG Optimus 4X HD] laufersteppenwolf:

[LG Optimus 4X HD] leolipop:
I remember having an Xperia Neo V last summer for which Sony had an online form where the owner filled its phones information and afterwards , sony remotely unlocked the bootloader for every device.

The end of the road is the same , an unlocked bootloader.Little importance is how to get there as long as we ALL get there no matter the software version. :)

I'm still waiting for the update... Mine is unlockable and the support tool keeps telling me that there is no update available yet.

UK?

I've been following this forum with interest over the past couple of weeks.

Does anybody have any idea when the UK upgrade will be released, used the various links supplied on this excellent forum which results in my code being returned as AGBRBK but after trawling through the forum I don't really see much mentioned of UK update, only Euro Open. Many thanks in advance.
[LG Optimus 4X HD] gordonbennet:
Thanks for replying. Didn't know that. You get the update through system update under settings? I still get nothing sadly.
[LG Optimus 4X HD] ronhoover88:

[LG Optimus 4X HD] tucina:
Hi.

My phone is AHASBK (Hutchinson/Austria).

Has anyone experience, how long does it take them, to roll out the official JB update?

I can wait a few days, but I'm not willing to wait for 2 or 3 weeks.

In that case I rather flash the euro open version.

Thanks
[LG Optimus 4X HD] tool_king:
In the past, the updates for our O4X always came about 2-3 months after the Euro Open version. (e.g. 10d was releaesed by Hutchinson in February 2013, while 10h for Euro Open was already released in November 2012 by LG).
[LG Optimus 4X HD] tucina:
OMG!!!

Ok, flashing right now, thank you very much.
[LG Optimus 4X HD] peppethustra:
LG Italy said that the principal reasons for this update are JB 4.1.2. and 3.1.10 kernel implementations.. I asked them why L9 got Qslide, but I didn't receive any answer, of course..

Oh, and about bootloader: official Italian change log says" bootloader sbloccato", which means "unlocked bootloader"..anyway, bootloader is only" unlockable, so no way to gain any other way to unloco it than a manual unlock..

I don't think so.. Euro-xxx are 100% unlockable (I unlocked mine few days ago), and here in general section there are some tutorials (about how to unlock 262-00, maybe 264-00 compatible), so I think it's a matter of time..

[LG Optimus 4X HD] skryptus:
Yeah, there will be a CM for LG 4X, but many people here (262-000, 234-00, some sim-locked users) might not be able to use it if they can't get their bootloaders unlocked. And if there aren't enough people using it, the CM people might discontinue support in order to focus on a phone with a bigger user base.

Is the UK never going to get the update? How do i download the Europe open firmware?

[LG Optimus 4X HD] :
Did you try flashing with phone mode in KDZ_FW_UPD.exe set to EMERGENCY? Try flashing doing a factory reset (from recovery perhaps) on whatever you are on now, use emergency to flash a lower version (preferbly stay within V20 range. ICS uses a 'different' API), do another factory reset, and optionally flash to your preferred ROM via emergency. V20B -> V20A -> Preferred or V20A -> V20A > preferred

I did it this way when i messed up my wpa_supplicant file hoping to get better battery and screwed up wifi.

But don't rule out the possibility of a coincidence that your Home button was just a hardware problem. I get that kind of moments sometimes.

[LG Optimus 4X HD] sandeeppandey:
Hey guys I have a strange issue with my phone. I am on the leaked V20A version, When i check show cpu usage from hidden menu i saw that most of the times only one core is working and they too at 100 percent and the rest only wake up for a fraction of a second and then off again. Is this normal?

I had read that there are issues with the activation of four cores in the leaked kdz. Iss there a solution?

I also flashed the euro open official version but with it the battery up time took a severe beating with battery going 100 to 0 in less than 10 hours and that too in standby mode without much usage.

Any help would be great.

Thanks.
[LG Optimus 4X HD] Jaydee239:
Nope, I flashed using the official way. Even waited until LG approved my dutch F/W. I tried flashing again using the official method, but the LG tool would let me (already was on latest version...).

So I tried this method you were refering to and not only did the LGPartnerSetup complete normally, the home button works :). Even better, all my apps were lost in one of the three factory resets but their back now. I had allready prepared myself for a few hours of downloading and configuring
[LG Optimus 4X HD] BigBoyPL:
Guyz after update from ICS to unofficial JB you are always doing Factory Reset.

Some man doesn't do this, he just leave his phone for about 30 minutes after update and phone booted. This can be important.
[LG Optimus 4X HD] laufersteppenwolf:
of course it boots, but it shouldn't matter for unlocking the bootloader...

imagine someone updates to JB, doesn't unlock the BL. then, some weeks/month later he's gotta do a factory reset, no matter why. then, again a few weeks later he wants to unlock his BL but can't because he had to do a factory reset?? that doesn't make sense ;)

Install the official v20a, root and uninstall unnecessary apps. Search for "battery drain".

Cores are interactive. In stock OS is normal, helps to save battery.

BTW, after flash, if you don't use LGFlash Tool, do a factory reset, before root of course...

Without any intention for being rude, if you don't understand the concept of rooting a phone, executing an app with root privileges, etc.. may be you should read more.

Busybox is a small application that executes 20 or something native linux commands. You better download the app from Play Store

But you shouldn't grant root privileges to app which you don't know very well or unsure

Does anyone else have problems with huge battery draing during night ?

Example,on ICS I would leave my LG at 10pm and wake up at 8am and it would drain eventually 1% battery,but everytime it stays at 100% ( no data or wifi connection ) and on Jelly Bean same setting and it drains almost 20% battery wtf ?

With Better Battery Stats it says 10 hours of deep sleep then who drains battery and uses processor/ram ?

I know some people also had similiar problem,is there any solution which excludes rooting and flashing or I have to root and then use some app like Greenify to turn off some LG bloatware apps ?

[LG Optimus 4X HD] RuedasLocas:
ICS or JB drain the battery because of the same reasons...

Don't forget that JB have wifi always ON as default setting.

Root the phone and un-install unwanted apps (search for battery drain and you'll find some users list of uninstalled apps).

I'm on JB and battery use is the same as before on ICS.

Instead of complain and wait for some kind of miracle, search and apply other users solutions. If it doesn't work report.

A lot of people will be ready to help.
[LG Optimus 4X HD] Capozz:
I have noticed the same behaviour. Even with background processes stopped via autostarts, deep sleep mode doesn't work correctly. V10H and unofficial V20A roms (same settings and installed apps) did not present the issue.
[LG Optimus 4X HD] leolipop:
For me it runs better then every.
[LG Optimus 4X HD] Insomniac535:
I seem to get a little more drain, but it isn't drastic. Was on standby for about 6.5 hours or so last night, with sync enabled, data and 3G on, WordFeud and Gmail push notifications enabled, and lost about 5% battery. A little more than I used to lose on ICS.

Check that 'Report from this device' is unticked in Maps settings. I'm not certain, but I'm pretty sure this was interrupting deep sleep and I can't remember turning it on, but it was turned on after upgrading to JB.

Already tried, but it doesn't seem to work. During night i have lost more or less 20% battery, even with wifi and 3g off. The problem, as you said, is that google maps starts randomly, interrupting deep sleep. I went back to unofficial V20A because it seems not to present an abnormal power consumption.

Anyway, thanks a lot for the suggestion :)
