what happens if you click it again? I was thinking if it works like switch, 1st click unlock, 2nd click lock...

Or may be some code or key combination or maybe battery discharge make it relock.

Or maybe it happens opposite what we see, i mean that popup maybe a confirmation to lock or unlock the phone

just kidding.

guys, maybe when theres the oficial ota update to jelly bean, we could use ota root keeper, for having root. That worked with brazilian 10c firmware wich was unrootable (patched) like this JB release is.

Did someone tried this method for root?

http://xdaforums.com/showpost.php?p=37268564&postcount=12

something like:

1. Downgraded my P880 to original 10h software using KDZ.

2. Rooted with Root_with_Restore_by_Bin4ry version from 13.09.2012

3. Used Root Keeper to backup root

4. Used Root Keeper to temporary unroot the phone

5. Updated phone to 20a by lg update app

5. Restored root backup in Root Keeper

Charged my phone to 100% battery, the tried fastboot oem unlock, and still phone hangs with no unlock. Dexter why can't you just post how you did it?
[LG Optimus 4X HD] Dexter_nlb:
i did what you did, maybe waited a few minutes before disconnecting usb cable and waited some mins again.

but even if i got "Unlocked" in hidden menu, its not solving any real locked bootloader. maybe HK edition release do have a bootloader enabling it.

Ok fair enough, thanks for letting me know.

[LG Optimus 4X HD] hernestwisnu:
No, KDZ nethod works just fine. Expect longer installation process, though; as this KDZ a bit bigger than the v10. I spent nearly 10 minutes just extracting the package.

[LG Optimus 4X HD] Dexter_nlb:
the extra procedure is pretty much trial and error maybe you find the way to unlock it, and you can report back here like many others did for now, which means no solution exists.

I removed all LG software and reinstalled all again, the most up to date files for my country (uk) then used the kdz hack install from this forum with the new rom.

http://xdaforums.com/showthread.php?p=37612066

No issues never even installed the PC Suite software just the driver and ran the updater.

Installed over 10h which was rooted with CWM.

Perfect after reinstalling Chrome. Brightness 100% works fine. No other immediate issues other than the lack of root but I've been using this for 12 hours and still have over 20% battery. Feels good actually.

General menu transitions/scrolling is a lot smoother, the music player app has improved A LOT, email widget got better, gallery app is better, some new icons/fonts etc, finally you can disable shutter sound, camera app better etc etc.. but the biggest thing that struck me is that a lot of transitions and stuff are much smoother.

[LG Optimus 4X HD] Flying_Bear:
ah, thanks. ^^

overall, the rom seems stable and nice, so i repeat, if you have any trouble (i had some with google play & some widgets), just do a factory reset, it should fix all the trouble.

on the other hand, anyone tried bluetooth? if bluetooth issue from custonexus can be somehow "patched" and fixed with this update, then i'll be flashing custonexus asap. a big thank you to dexter & other devs, and everyone who made this happen.

[LG Optimus 4X HD] donkanmcklaus:
so, can we unlock bootloader with those commands?
[LG Optimus 4X HD] Dexter_nlb:
yes, with some patience as i cannot re-lock it, and i cannot confirm whatever procedure i used..

i suppose it has to do with patience, since it did some wipe/factory reset when it worked.

i also know now, that you cannot flash back to euro v10h, it wont boot into any recovery and only working start it s/w upgrade.

so it seems when you first flash this beta v20a, there is no returning back with kdz install from 4.0.3 anymore. lets hope that is no concern when final comes out.

maybe it will work with a enter recovery + wipe factory reset in stock 4.1.2 and then kdz back to v10h??? didnt test that one yet.

Re: Official JB discussion Thread *DL-link available*

Previously I had Motorola RAZR and there is no way to downgrade system because they implemented secure version number to some partition and when for example on ICS partition has secure version 3 after upgrade to JB sec ver is upgraded to 4, after that there is no way to flash back partition with sec ver 3.

Short version - if you upgrade to JB you can't go back.

it would be something like

but this will only fix the broken apps that rely on external data stored in the old "/sdcard/external_sd" folder. i doubt you are able to do it without root.

for your games it would be something like:

ATTENTION!!! Don't do this, its just an example!

a. mkdir -p /storage/external_SD/Android/obb

b. mv /storage/Android/obb/* /storage/external_SD/Android/obb

c. rmdir /storage/Android/obb/

The problem is that old kdz does not downgrade bootl, but new kdz upgrades it, and last is not compatible with old rom.

So, a way to downgrade bootloader should be found, or a way to modify system.img.

The fact, that it notes "bootloader unlocked" on the s/w upgrade screen may mean that it MAY allow to flash modified kdz files.
[LG Optimus 4X HD] Navios92:
Wrong !

On my Optimus Black we can flash old GB kdz and use old bootloader.
[LG Optimus 4X HD] Vosetal:
I don't want to downgrade, but for those who trying maybe that other kdz method with b2b tool or hacked suite can work?

And another thing (maybe stupid). Maybe first original rom contains bootloader and next roms only changing system partition (long shot).
