Thanks for the tool - I have a question: Having got root on the 20A I click on option 2 for unlocking the bootloader. Can you provide a procedure for how to proceed? After the reboot into unlock menu I hit the volume up button and "Download mode!!!" appears. Nothing happens after this - no files are transmitted. If I pull out the USB cable, a new line comes up:"Running factory reset for the first bootloader unlock!! Please wait". I have waited for 10 hours.
[LG Optimus 4X HD] peppethustra:
After that message, wait 30 seconds, pull out battery and re-insert it, then reboot the phone with power button..check bootloader status on hidden menu (3845#*880#), if it says "unlock" you job is done.. ;)
[LG Optimus 4X HD] brunek:
If I unlock bootloader and install recovery with this tool will I lose all data on my phone?
[LG Optimus 4X HD] tool_king:
Yes. A factory reset is part of unlocking the bootloader .
[LG Optimus 4X HD] pvfos:
Sorry, this dont work either. The problem could be the installation of the fastboot once Downloade Mode is visible. The computer cant find the drivers. Can you help?
[LG Optimus 4X HD] pvfos:
Installed Fastboot (CT_HsPhone_General_Drivers.rar). Got unlocked. Thanks.

Hello,

i have the same problem to unlock my bootloader. Can you give me your way for unlocking yours ?

Thanks
[LG Optimus 4X HD] pvfos:
What I did was to execute option 1 in "All in One" and then install the fastboot driver (http://xdaforums.com/showthread.php?p=38953792). Then unlock by option 2.

Hey OS_Hacking! :)

You did a really nice job on this tool, it's SO useful! :D

I found out that the bootloader unlocking step works with some of the 262-000 devices, too! :)

I tried it with your tool and... just look! :D

Maybe you can add it to the OP, so everyone can see that some 262-000 devices are unlockable with this tool, too! :good: :victory:

BTW, had a german 20A and a Vodafone.de SIM-Card in it before unlocking... :cowboy:

So you can press "thanks" if you want :D

I think factory reset time depends on how many files and apps you have installed on your device before unlocking ;)

Hi OS_Hacking,

Can I flash the EUR-XXX firmware by kdz then use this tool to unlock bootloader?

[LG Optimus 4X HD] roger321974:
why the dev profis here have no solution for the bootloader? post an copied manuell is easy, but for 50 percent of the people dont work, because LG has his fingers in there or LG have make mistakes.

the guys who have bootloader unlocked and have skill in android systems can search for a solution for the 50 percent persons. i think we can stop the experiment to unlock bootloader for all the people who havent unlock.

all peoples have to do something aka update driver, use other OS and more. nothing helps.

Deinstalled the drive again, installed the additional driver from this post an installed the included driver.

Bingo - it worked! :laugh: :good:

Yesterday I updated to 20a from 10h, phone is EUR-XXX.

Rooting did not work with [All-In-One], so I used this.

When I use option "2" - unlock bootloader, the phone reboots, I see a tiny red line of words (too small for my old eyes) in the upper left corner for some seconds.

Then phone reboots again and starts in charging mode. :(

:confused: What should I do to get into the unlock mode? :confused:

Installed under Win7 x64 is "LG United Mobile Drive 3.8.1" (I tried the integrated driver too).

Everything was running with administrator privileges.

- uninstall all LG drivers

- unplug phone from USB

- install driver from here (I used the left button with asian-fonts)

- start all-in-one-tool as admin

- choose install driver

- attach phone to USB

- check in device manager to see if everything has been installed for the phone

- start "2" - unlock bootloader

This worked for me.

Good luck! :good:

Could this tool be updated to include the new bootloader unlock method, i.e. the one that works for every bootloader?

[LG Optimus 4X HD] Afro:
Normally, if you used this method from the AIO-Tool, it should have done a factory reset after unlocking itself...

If not, you're just lucky or you didn't get the unlock :D

no didnt used the AiO-Tool, just a *.bat file. and after manual reboot, under hiddenmenu it says "Unlock"

I believe you can. Just try it your self first, if you can't unlock with this AiO, use other method to unlock bootloader (use find in this forum) and then you can go back using AiO to install cwm

Unlock Bootloader

Hi!

Thank you very much for your tool - so usefull.

Unfortunately everything was fine, but unlocking the bootloader. I've found a solution here:

http://www.android-hilfe.de/anleitu...g-alle-bootloader-oeffnen-tester-gesucht.html

It's as easy:

1. root your phone

2. install any script Manager from Play store

3. download the script from the webside

4. execute the script with your script manager - but don't Forget to grant root

Good luck!

[LG Optimus 4X HD] xetz:
Sorry for being a noob...

1. Can anybody tell me what is "Un-Secure Boot" for? Is it so that I can flash custom ROM/kernel?

2. What is "Gmod-Boot-Menu"?

Thanks
[LG Optimus 4X HD] Afro:
Hey, see you have to turn it off. But after that, you have to turn it on with Powerbutton + Volumebutton (-), to boot into LG's Recovery and choose the second option (I think :D )... :)

1. I don't know exactly what it is, maybe another guy can help you better... Of course it's the opposite of secure boot.img :D

2. "Gmod Boot Menu" is a recovery menu in form of a collection. These options are implemented:

-Team Win Recovery Project Recovery (TWRP)

-Clockworkmod Recovery (CWM)

-Aroma File Manager

-Fastboot

-Reboot

If you choose one of these options, it will reboot and do what you chose.

But it has some issues and the developer of this menu removed it from xda, it's to risky to use it :o

You are a gentleman and a scholar. THANK YOU VERY VERY MUCH! BTW I'm on jellybean in europe for anyone that cares. it was easy ; boot into recovery by turning device off and turning it on by holding power button and volume down button. A red menu should appear. After installing drivers start the windows program and press 1 to root. Then on the device bootloader select the option which says "ADB....." (for me, there was no ADB slidload option) - then connect device to computer and it should root. Please PM me if you have a problem, which you shouldn't have because this program is so easy to use!! :D

Hey Guys,

I am familiar with the LG L5 Methods but not with this one and i need some help.

Gonna buy this phone. But i need some help of you. Is everything working good in this All in one tool? Tomorrow i will get my phone and i am going to upgrade to 4.1.2 and i am going to install 4.1.2 MOD.

I understand everything until GBootmenu. I understand that Gbootmenu will give me a menu where i can choose how to boot ( Do i need CWM and GBootmenu? Ore is GBootmenu enough? ). but then i see Secure boot and Unsecure boot In this thread.

What is the Secure boot meaning and the Unsecure boot? Need some explanation thanks in advance.
[LG Optimus 4X HD] Rudjgaard:
GBoot is just a screen where you can choose to boot into cwm touch, twrp, fastboot or aroma file search

The tool works but the recoveries are a little buggy atm. Twrp almost messed up my display giving me a huge scare...secure and unsecure boot are just a way of booting with or without immediate adb support if i'm not mistaken
[LG Optimus 4X HD] gordon0001:
Yes, TWRP v2.4.4.0 has a criticial bug. I do not recommend to install TWRP v2.4.4.0 or GBootMenu (--> includes TWRP v2.4.4.0).

I tried to unlock bootloder but hidden menu says its lock what I have to do now?
[LG Optimus 4X HD] voon:
Same here ... with my P880 (Euro, Switzerland), I just get LG Security checksum errors when I try to boot recovery. I tried TWRP. When this gave this error, I tried the CWM option of this tool here, but same error. Unlocking doesn't seem to work? When I chose unlock, it asks the up/down question, when you chose up, I also get the red Downlaod Mode!!! Message ... when I unplug the phone, it says I have to wait, botting for the first BL unlock ... but nothing seems to happen.

EDIT: Found a solution for my euro 4.1.2:

1. use adb shell to get to your phone, su root (adb is around in many tools here ... use any adb. Requires LGs USB drivers to be installed and the phone is recognized by windows)

2. Use "cat /sys/firmware/fuse/odm_reserved >/data/local/tmp/odm_reserved" to generate a textfile in the tmp directory

3. Go there by filebrowser and edit that odm_reserved file. Inside is a large number: 0x0000000000000000000000000000000000000000000000000000004000000000

4. Change this number, so that the last two zeroes read c8: 0x00000000000000000000000000000000000000000000000000000040000000c8

(the forum inserts a space in the numbers, which doesn't exist in the file ... do not add a space, it is one big number)

5. Save the file

6. Now the reverse: "echo /data/local/tmp/odm_reserved >/sys/firmware/fuse/odm_reserved" ... not that it is echo here, not cat

7. That's it, your phone is unlocked. You can check that by going to the numberpad of the phone, enter "3845#*880#" for the secret menu and check the unlockstatus (further down in the menu)

Now you can happily boot CWM etc, that you installed with the All in one Tool.
[LG Optimus 4X HD] IceTeaDestroyer:
Thank you!

I will try it soon.

Turn on USB Debugging?
[LG Optimus 4X HD] voon:
Yes, for adb to work, USB Debug must be on. Just let the OS discover the device properly and switch it to LG Software mode. If you get "no device" from adb, then the OS hasn't recognized it or you havent set it to LG Software mode or something.
[LG Optimus 4X HD] IceTeaDestroyer:
I stucked at this point, I am so noob...

Sorry for small pic.
[LG Optimus 4X HD] voon:
Erm sorry, but I can't read anything on your picture ... might want to present a clearer image or type the error you get?

But from what I can guess is: You are only in a Windows directory called ADB shell? You actually need to run the command "adb shell" before doing the cat command. That will give you a (linux) command shell on the phone, where you can then run that cat command. You do not run the cat command on the windows cmd shell, but inside adb.

Hey $Parker,

OS_Hacking is not active anymore, his account on XDA is "currently disabled". He got named in credits, and I am still happy that he gave this tool for us.

But it had an old recovery and got no new functions, that was the reason why I talked with eagleeyetom and he gave me the ownership of this thread. He is a senior moderator and I guess he knows what was the right thing to do.

If you want to use the old tool, I don't care, just do it ;)

But in my opinion this great community has to get some updates, and I know I'm not the only one who thinks that. :D

Have a nice day,

Afro
[LG Optimus 4X HD] $Parker:
But even so .. You should ask him .

He wrote on the Optimus 4X facebook group that you didn't take his permission .

But if his account is disabled , this should be OK .

It would be better if someone handle his Tool .

Anyway , sorry if I was indecent .
