I probably don't understand you...but i never had V20A... I had v10d and I updated my phone with kdz file to v10h....but now i can't update my phone for some reason to V20A and on history it says like i have/had V20A :confused:

You did not bring anything new and nothing not that was tried before, and you claim you did something revolutionary?!?!

You just packed well known, and many times retried steps from before, and you expect it will work?!?!

Bug

There's a bug in the EU official release that's causing messages received to not recognise the contact i.e its coming up with their number instead of their name and icon/picture.

Anyone else had this problem?

Thanks in advance!

Hello. My phone is with V10D, and i want to upgrade to v20A. Im from Bulgaria and i know people with v10H phones with Jelly Bean upgrade by LG Tool but when i check with LG PC Suite ot LG Upgrade Tool it says that there is no upgrade for my phone. The strange thing is that when i use the Software Update app on my phone it says there is update and i have to connect to PC Suite to upgrade. So is there any way to upgrade my phone using PC Suite ot LG Tool. Thanks.

There's no Qslide, battery life is pretty much same as on v10h, right now I have around 200 MB free...overall, the phone is much snappier in menus - project butter is doing its job :D There are some visual changes, new wallpapers etc, nothing too important, but it's nice to see...about the performance, I tried to play D-Day by GLU - it has lags just like on ICS...note that I'm not rooted and I didn't make system reset before the update, just updated over the LG Support Tool

[LG Optimus 4X HD] teddyxfire:
And a little sidenote for those who didn't know: JB's Project Butter uses a lot of CPU power as soon as you touch the screen, that's why JB is much snappier in menus (constant 60 FPS) than previous Android versions...because of that, battery drainage could be faster than before, especially if LG's dev team didn't do the proper coding (I hope they did). And a little speculation - maybe they rushed this update a little because their officially announced deadline was over (Q1 2013), so maybe we can expect more minor updates in the next few months...or they can just release the way to unlock the bootloader and provide the kernel source code so the devs can start with proper custom ROMs and kernels :) I'm glad that LG released JB on time, just a few days after the announced date.
[LG Optimus 4X HD] JustChris20:
Because they forgot to release an unlockable version for germany. So they have to patch something to make it unlockable... :D

there is a thread for downgrading, search it.
[LG Optimus 4X HD] skryptus:
That's amazing and all, but I thought this was a discussion thread...

I mean, I get that people asking questions that have been answered might be annoying for those of us that keep checking this thread, but for those that just got off work and found everyone talking about the official update, maybe they're not up to reading the 30 pages created since the update got out before they can ask for help.

So for anyone willing to discuss a problem with downloading or installing the firmware upgrade, I'd say yes, this is the thread to talk about it.

For those ASKING if it's out for their country, I'd advise checking the (now-updated) firmware webpage and/or the thread about "JB release announcement" we have (I believe it's still at the first page). For those wanting to know the changes, check the changelog also around here.

Hello together, I am new to this thread and followed it for quite a while.

I bought my 4X HD in germany and my firmware was V10H, so today I manually flashed EUR OPEN V20A.

I rooted my phone successfully. Now my menu shows: P88020a-EUR-XXX and I suppossed I could get the bootloader unlocked.

BUT: It doesn't work. All drivers are installed but After typing in "adb reboot-bootloader" it is stuck at the LG Logo and if I

try typing in "fastboot oem unlock" the cmd box shows "waiting for device" and nothing is happening.

So I went ahead and checked my IMEI and found out it is "ANLDBK" and not "ADEUBK" for Germany ?!?

How come I can't unlock? I have EUR-XXX V20A and root and all drivers ... Any suggestions?

[LG Optimus 4X HD] Vosetal:
Maybe is smarter not trying to unlock bootloaders, at least for people who not intend to be a kernel developers, because it is possible to make your phone permanently unlockable if you do something wrong (stated by RC from CM). Also we still don't have any custom roms so its not realy necessary ATM.
[LG Optimus 4X HD] laufersteppenwolf:
you need the drivers to get fastboot working ;) better way: use a linux distro ;)

[LG Optimus 4X HD] @non4:
I was thinking, can we not play with 2nd init and bootstrapping to get some roms made for locked devices? The new kernel will probably be more compatible with this sort of rom. Just look at the motorola defy forums, theres some brilliant, bug free jellybean roms, even a PlayStation certified one, yet bootloader is 100% locked with a crappy froyo kernel. Any devs stuck with locked device should not be discouraged :thumbup:

Well there are ROMs for locked bootloader like ours out there, so we can have ROMs too, but the I dont think they`ll make Roms for ppl who has unlocked BL and for locked BL. The only think is that we wouldnt have custom kernels..
[LG Optimus 4X HD] :
That's the problem as I unlocked the bootloader I type fastboot flash recovery recovery-6028.img that didn't work but after that under please wait I get the hint that is finished.

Major bug again

Both in the betas and in the official jelly bean i face the same major problem :

When i want to end a call the screen doesn't light up when i move it away from my ear.

This is ridiculous! I don't care about bootloaders and nvidia drivers.I want a phone that functions correctly in the most basic thing :The calls!

Is there a solution for it or do i have to return to the official ICS which was working perfectly?

[LG Optimus 4X HD] laufersteppenwolf:
of course it is possible, and should also be easier as for the old stock kernel. but we first need a bootstrap recovery, before we can try to port one. and like you've said, the new kernel helps us to be able to port it easier, cause this kernel shuld be used more often on tegra 3 devices ("cherry-picking" ;) )
[LG Optimus 4X HD] profyler:
To test and eventually to calibrate the proximity sensor, you can use hidden menu (dial 3845#*880#) -> Device Test -> All Auto Test Menu Full -> ALC / Proximity Test.

You can even test the "auto brightness mode" (to test also the light sensor) and "enable proximity wakeLock" (to simulate a call).

To test the sensor just put a finger near the sensor.

There is also a "Calibration" feature to calibrate the sensor if needed.

In the defy 2ndinit was used to go into a bootmenu it installed, from here you could go into recovery. The good thing was you could boot into bootmenu with volume keys, thus being able to recover soft bricks. Also you could change the cpu governer, voltage and frequencies here which stuck to boot. Remarkable piece of hacking, would love to see something like this. Screw the bootloader!

To all those having problems with contacts only displaying numbers.

Backup ALL your SIM and phone contacts, then erase all the contacts on the SIM(you might need to use an app from the Play Store). Then, copy all your phone contacts to your SIM and then restart the app. They should turn up normally afterwards, even when adding new contacts.

2nd-init will not get you cm10 in a good way, no cm10 devs will support it and only hackers can work well with it.

cm10 developers just need release the work for the open devices and ignore the rest, and let others try to make it run on a locked device, if anything should happen.
