[MENTION=4716493]laufersteppenwolf[/MENTION]: Please update your FAQs OP in terms of available custom roms instead of "which one is best question" and add your custom rom and in point 3 your kernel. I think it would be more useful for people having all information in one thread if they are new in P880 forum like me.

I'm coming from LG Optimus 2x (P990) and as I'm not allowed to make posts in dev section I'd like to ask you for looking in the P990-Section for kernel hacking stuffs, because there is a group of kernel hackers who have made a real good kernel for the 2X (Kowalski Kernel: link) where we can adjust also Wifi transmit power. Maybe this can lead to a longer battery life on P880 as it does on P990.

Thanks

Kevin
[LG Optimus 4X HD] laufersteppenwolf:
i will update the OP later ;)

and about 2x, it uses another chipset. so it's completely different stuff ;)
[LG Optimus 4X HD] McKevin78:
Hi,

I know that it's a different chipset but, I think, in principle it must be possible to adjust the wifi transmit power like in Kowalski kernel.

Cheers

this might be a frequent question...

what is the best and more stable rom for everyday use(camera,fm radio...)?

thanks in advance
[LG Optimus 4X HD] @non4:
Official jellybean IMO, cm10.1 doesn't have FM radio included. There is also ZAIBEN ROM which I am using now, has a few tweaks and some bloatware removed. And if you play any heavy games I recommend you use IODAK kernel with it

Hello, do you phone has support for H+ network?

I have stock JB, rooted, and i dont have H+, i have excellent signal, i only have 3G/H..

I put a custom rom zaiben, and the situation is the same, I have no support for H+, i have only H.

I put CM 10.1, and voila, i have H+, very strange...

How is it that, on the stock rom and custom (zaiben) rom no support for H+, and CM 10.1 i have H+..

Is there a solution to this problem?
[LG Optimus 4X HD] @non4:
I think H+ is only displayed in 4.2 roms, stock just displays both as H

Werewolf v005 update

Hi. I recently installed werewolf v004 ROM and kernel. I want to update to v005. Can I do that by flashing the v005 kernel or do I need to re-flash the whole ROM? Sorry for the noobish question :p

the easier way is to simply update the ROM. no data loss, nothing :D except for updated CM sources :p

How to prevent screen from dimming?

Is there a way to eliminate the dimming of the screen after 10 secs of screen on? It is quite irritating. Any setting change, to keep it at the level of brightness set, will be of great help. Tried searching the forum but could not find any answer. I have V10H rooted.

Thanks.
[LG Optimus 4X HD] kelly66:
I am not talking about the screen timeout. Timeout is set at 30 secs but after 10 secs the screen starts dimming unless you keep touch the screen. Is there a way to prevent this dimming? I want brightness to stay at the set value until it times out.
[LG Optimus 4X HD] kelly66:
Thanks, FD1999. Actually, timeout was set at 15 secs earlier (not 30 secs) hence 5 secs prior to timeout time it used to dim. Now I have set it at 60 secs and it dims at 55 secs. So it is only dims 5 secs prior to time out time. What a big relief!

Upon upgrading to JB my rooted phone went back to normal or automatically unrooted

My phone automatically unrooted when I upgraded it to Jellybean. Is the root process the same if it's Jellybean? I am stuck at installing the apk file in my phone because it says that 'unfortunately, SystemBackupTest has stoppe.'

Please do guide me with this friends.

hello,

what's the meaning of UNLOCKED LG 4X ? Does it mean UNLOCKED bootloader or an open line phone ?

thanks :p
[LG Optimus 4X HD] @non4:
Depends, if you mean it says unlocked where you bought it it means sim, however if its someone here talking about it 9/10 times its the BL. Especially for ROMs, no ROM requires sim unlock so if it says unlocked you know what to do ;)

[LG Optimus 4X HD] hpham1191:
Hello, I just got the Optimus 4x HD and have a couple questions. How do you know if your phone is branded? It's definitely unlocked because I'm able to use it for AT&T. My version seems to be P88020b.1e581aa4d9, which I assume is v20b. Am I out of luck in the modding department?

I'd really like to install a custom rom, but I haven't been successful in unlocking the bootloader and installing a custom recovery. The phone is rooted, but that's as far as I've gotten.

Thanks in advance!

Hey so I just bought my lg optimus 4x hd and it's trying to scan my SD card but it's not working

It stays stuck at 61 % (I tried deleting all the files, formatted my SD-card with SDformater too but still not working.

Yes I tried turning it on and off again but it's still not working, also tried removing the card and all but nothing is working for some reason...

Also when I try checking for new software updates with the Software updater version it says it's the most recent OS version while it's still on 4.0.3...
[LG Optimus 4X HD] profyler:
Do a hard reset (make backup) and check with another \sd card , may be you have a faulty one.

To have jb, you need to know what carrier you are and whats the phone origin (country)
[LG Optimus 4X HD] Ozomahtlii:
Looks like that fixed it for the SD card, Thanks!

And my phone is from Spain, bought it on amazon, and isn't the carrier not related at all to the actual android version?

Edit: after a lot of googling I found out you have to install it through your pc, I'm used to my nexus 7 where it came on my tablet and not through pc, thanks a lot

[LG Optimus 4X HD] eatfoodnow:
So I just got my O4X in the mail today (unlocked version off amazon), and I'm wondering what my first steps should be. I have my service set up with Straight Talk, and that's about it.

Ultimately I want to have the latest stable CM on there (looks to be CM10.1.2), with the most up-to-date firmware and everything. I just don't know what order I should do things in, when/how I should backup, etc. I'm pretty familiar with UNIX/Linux but not with Android yet since this is my first smartphone.

If anybody has a complete (from stock phone to CM10.1.2 with updated firmware) guide they'd recommend/write for me, I'd be very thankful.

I also want to save my contacts since I've already put in some of them.
[LG Optimus 4X HD] Aei10:

i had a xperia mini already, it worked really slow even in simple tasks such as loading gallery, as you know it has 1GH cortex-a9 cpu,

1- LG 4xHD Has 4 tegra3 cores plus 1 core instead of reducing battrey use, i wanted to ask you, can this single core process the tasks easily without any hang?

2-when the other cores operate?just in gaming?or when the single core doesnot be able to process?

3-is there any Probability to appear dust under the screen?

4-is there any chance of pixel burning after a time working with this phone?
[LG Optimus 4X HD] @non4:
Lol, the original x10 mini pro was surprisingly smooth! It only froze up when using live wallpapers. Pure stock never rooted!

1: A program called tegra over clock can lock the phone into the LP core, the phone is still usable, but it will feel like your xperia :P

2: They will operate as and when required, to cope with any heavy app, including games. If you use a custom kernel with cpuquiet enabled, use the "runnable" gov, it only activates a core when a process can actually use it, deadly efficient.

3: No dust in mine, it has happened but its rare

4: Unless you mess with the thermal protection I doubt it

[LG Optimus 4X HD] amraii:
Thanks for your response;

in fact i prefer original room to custom room;by this supposition that we just use of the original room 4.1.2 that released from LG instead of using custom room, do we feel leg with the single core?

this single core really made me worry and is changing my decision to buy this phone...

should we install tegra over clock program our self?or it is installed on p880 by default?

Sorry to interrupt your discussion: But wasn't this thread titled "Frequently Asked Questions about the LG Optimus 4x HD"? Aren't you going a bit too specific in different areas to fit that?

[LG Optimus 4X HD] Ozomahtlii:
First of all, the problem I'm having is that my phone will not turn on completely 9 out of ten times giving this error:

[LGE_security] ERROR: boot image signature

[LGE_security] 5 seconds after power is turned off for Battery saving

I'm having this error probably because I tried partitioning my SD card using ROM manager, an app in the play store which had a function partition sd card

As I had no knowledge of what to do I just pressed it as an idiot and chose some options and since then when I turn my phone on it gives me that error and powers off again.

I'm trying to install cyanogenmod with this app but it needs to reboot to do as such and fails every time as I have to manually power it on and off multiple times before it turning on completely again

Anything I can do about this?
[LG Optimus 4X HD] black@pirate:
HI, I will receive my O4X tomorrow. Before I have it in hand, I'm doing some research whether it is being loved by developer or not. (my last device, asus fonepad, is negelected by almost all dev on this world :( ) Now, I've a little question. Please bear with me if I sound noob. :D

I want to know whether it is possible to unlock bootloader in stock ICS? (guess not, but I want to be sure :) )

If not, do i need to upgrade Stock JB or any other custom JB will suffice? ( I've read somewhere that we can install custom recovery in ICS, so I'm guessing we can flash custom rom?? )

Thanks
[LG Optimus 4X HD] Flying_Bear:
you need stock jb to unlock bootloader. ;)

custom recovery on ics doesnt work like normal recovery, you start it when your phone is already on, and you cant install custom roms
[LG Optimus 4X HD] black@pirate:
Thz for clearing up. So, I am going to download stock JB rom now. Just one more question, I don't know what kinda version of P880 I'll receive. I live in some remote country in South East Asia (if you wonder the name, it is called "Myanmar" :D), so in my country, we have various versions of device. We have international version, Asia version, US version, and for LG and Samsung, also korea local versions. I just don't know what versions I will get. But after trying to read all the threads here, I guess I can flash whatever version on P880, right? So it is safest to download Europe Open coz it is the only version in which bootloader unlock works best?
[LG Optimus 4X HD] Flying_Bear:
myanmar, aka burma :p you still have those unrests with buddhists and muslims? :p rohingya still persecuted? :p

and yeah, you can flash any kdz version, and bootloader unlock works on any version. if you're gonna replace stock rom with custom one, it doesnt matter which one you flash ;)
[LG Optimus 4X HD] black@pirate:
Wow, I can't believe My country is that famous :D but not for a good reason :( Thz for your help. That really clear me up.

For your question, I'm afraid I can't answer it. If i write something wrong here, I can be arrested coz the goverment spies are always lurking. (Just Joking :P)

Actually, right now, I'm killing a rohingya with a rifle shot in the head, coz he was setting fire to my car. LOL, (joking too)

JB problems

I updated my phone optimus 4X HD to JB. Now, when I install a new app , its speed becomes very slow for a moment. Always its RAM is full and total free memory when I kill all apps is about 200 meg. In my phone, when HD games want to load their data, they are closed without any alert. :(

Please help me.

How can I solve this problem? :confused:

should I rollback to ICS? :rolleyes:
[LG Optimus 4X HD] dimi89:
Yes when you install new app stock JB tend to get really slow for about 3-5 secc then it goes back to normal (lg was playing a bit with launcher).First thing you should do after upgrading to JB is Factory reset and then start install apps from scratch because apps tend to misbehave when you just upgrade OS without wiping.Do thins then test your new device for at least 5-7 days and report back.As for low memory,you should know that free memory is wasted memory in android and that device will kill automaticly apps that you arent using if some app that you are running demands more memory.also read LG forum,posts etc.
[LG Optimus 4X HD] akmepe:
tnx

TNX

I upgraded my phone 2 month ago, then I did Factory reset. In spite of all that, the before mentioned problems exist.

I can't understand this expression : "then start install apps from scratch" .

Why the HD games leave when they want load?
[LG Optimus 4X HD] dimi89:
I ment that you should install apps all over again after factory reset.I dont know what HD games are you playing are they fro market or you found them somewhere else and downloaded them.

it's not unlockED, it's unlockABLE
[LG Optimus 4X HD] youngchaos:
And it's not reversible,right?
[LG Optimus 4X HD] Flying_Bear:
it seems to be reversible, by using fuse method; some people have sent their device to LG repair center with unlocked bootloader, and they got it back with permanently locked bootloader.
[LG Optimus 4X HD] youngchaos:
tell me,is for you worth switching from Ascend P1 to LG P880 ?! But i like modding,like switching Roms.. With Huawei i have 0 problems ,with LG i have to unlock the bootloader and cross fingers to have no need of Warranty.. mh?! Worth?!
[LG Optimus 4X HD] @non4:
Well its quite easy to downgrade to ICS and then they can't tell its unlocked without upgrading. If the device is in a state where you can't downgrade they probably wouldn't be able to tell in that case either ;) more of a concern is my water sticker turning pink over time, its never really gotten wet apart from occasional raindrops and sweat (I unload 1000 tyres by hand from a lorry in 30mins :D) but a good case would probably prevent this.

[LG Optimus 4X HD] Fluoxetine:
Problem could be that you are using an ota incremental update from 05 to 24. that's a 2 week jump, perhaps you need to go to 06-07-08 etc. So i suggest downloading the full Rom from Mokee dev page of the latest nightly.

Status 7 is usually get.prop error, that which identifies your device. It aborts if it's not the right device, so may have been also a corrupt download, or as i said above just too big a jump for an incremental update.

Okay..Seems I will have to flash the latest Mokee ROM rather than trying the incremental update. Anyways, Thank you so much :D
