[Q] Noob Question - Please Help - LG Optimus 4X HD

I'm a total noob when it comes to rooting, I don't understand any of it. So, here is my problem: I've got an LG 4X HD running Android JB 4.1.2, after I installed the official update a while ago. I'm tired of the newer official updates not coming to this device, si now I want to root it, put 4.4 KitKat on it and make the led notification work. So, if someone can guide me step by step through the rooting process, I would be really grateful. I have read all the posts regarding this device, so please don't give me links to other posts.
Thanks in advance!

You can't just root it and then put KK on it. If you have problems with rooting you will find it unbelievable difficult to unlock bootloader what you need to do in order to install a KitKat custom rom.
I would suggest you to whether read more and try it or just don't do it. If you don't understand how to root you LG 4X HD you will run into big problems

I have just managed to root it. Now I'm trying to unlock the bootloader, but when I'm in /cmd and enter "adb reboot oem-unlock", it says "error: device not found". Can you please help?

You need to install the right drivers (maybe manual).
But those questions been answered many times, please search XDA for the solution.

Go to setting - about phone - software update
uncheck 'wifi only'
then select software update
If your region have any update, you will get it.
But keep in mind in case of any messing you must need PC, so i recommend do it only if you can hold for PC.
I go with getting ahold of a PC..
Possible to OTA update on 3G but it will be painfully slow..
As for custom ROM's see if you can use a friends PC - AS it's handy to have the installation steps there for reference if you've not done much of this type of thing..
Thank you so much master ketan, I'm afraid I can't use a pc since I just moved far away from home, and still new here, and has to make new friends, and anyway wish me luck!!!

Still, it is a bit risky to update to ICS without having access to a computer. If there is some problem will not have access to tools for troubleshooting. I would prefer to wait until having a computer in hand. cheers.
success ive successfully mamaged to upgrade the software, and then finally able to flash cwm and rooted the device, next step flashin a custom rom=),

Yes, there is a lot of reading to do, if you want to study it all.
I dont think SuperOneClick is meant for ICS, I will recommend you to look at this:

And then I would suggest you try option 2 in "How to get root". You dont need to download ICS, you already have it.
Good luck.

[Q] Rooting problem

I´m in need of big help, i was rooting my device with smart flash tool and it all went well until the phone rebots and appears the message "security error" under the LG logo. What do i do?
Please help, it´s an emergency.
You can see alot of questions here with that security error issue. Just download a kdz of a gb rom and extract it. Then flash with sft

And will that make the phone usable again? Another question, why did that apear? My phone is locked to a company, and the ics rom that i was using was the original but for unlocked phones, it´s that the problem? Do i need to use the rom for the locked phones to be able to root it to ics?
It will. Aslong as you can go to s/w download. I dont get what you just said cause im no expert. i rooted my phone wth stock ics with unlockroot.com . but i have the ku5900.

My phone it´s locked to a company,(like at&t, vodafone, etc etc), and i was using the stock rom from lg (v30b), but for my country that version is only avaliable for unlocked phones, and i was using it.
Then you did something wrong maybe. I had that security error when i tried to flash cwm with ics.

Linux question!!!

Hello. I have one question. I am having an optimus 4x and i am running v20a....262.001. First of all i loved cyanogen on my old optimus 2x and i want to use it also on my optimus 4x. I know that i have to use euro open v20a,to unlock bootlader, so this is what i have tried: downgrade to v10,update to v20a euro open though kdz updater, and the results?? Cmv was still there(do not know how ). I believe some of my drivers are to right(btw, i am using win7 64x). I am not the best linux user, but i think i can handle them... so i was wondering how can the hole operation be done from linux environment. I use linux on an external usb flash, so i can boot it whenever i want. So iwas hopping that someone could guide me to do the downgrade, and the upgrade the rooting, the recovery install, the bootloader unlock and the cyanogen install.... all from linux environment..... :angel: :angel: THANK YOU REALLYYYYY FOR YOUR TIME IN ADVANCE!!!!

You can't down- and upgrade on Linux. KDZ flashing only works on Windows.

Ok. If i downgrade to Windows, can you guide me to the rest of the procedure??

Android 4.3. ROM failed

I am having problem installing Android 4.3 on my HTC Nexus One. I've already opened a thread for that and the guys there recommended me to ask you here.
This is the source thread - I will really appreciate any help that you can give. Spent all day trying to solve this without any luck. Thanks.
In the op of the 4.3 ROM you want to flash, there should be the partition size needed to work. Do you have the blackrose bootloader? If so, what is your partition sizes? If not, then this will need to be done first, just check developer forum here for download and instructions
