No exploit will work... LG fixed that.. damn lg
Anyways why did not you search before, there are a no of threads regarding rooting.
Use cwm injection method and flash your rom again. http://forum.xda-developers.com/showthread.php?t=1512203
By the way you should try other custom roms here as well rather than stock.

First of all, since you're new to this board please read the Welcome To The LG Optimus Black Section..... (Please Read If You're New)
Also, read the [HOW TO]The Big N00B how-to! since it will answer most of your questions.
Second, if you would have searched you would have found your answer already, but i'll help you (i'm in a good mood today too ).
You can find an already rooted v20E firmware HERE.
Just follow the steps from THIS post but instead of using the V20B firmware files use the ones from the V20E firmware (i've already given the link to the V20E above).
Good luck and happy modding

Can't wipe data/factory reset

Smartflashtool has stopped working
Hi, my OB also has v20E firmware installed by default. I 've tried to root the phone by using smartflashtool method that has already been described above. However, whenever I tried to root my device, it always ended up in failures. The smartflashtool program either showed "Timeout error is occurred" (sometimes) up or "Smartflashtool MFC has stopped working" (most of the times) at various points in the rooting progress
I used all of the programs mentioned on the posts above but still no luck
- Installed LGSmartPhone_ModemlinkDUNDrive_WHQL_ML_Ver_1.0
- Installed LGWindowsMobile_USBDriver_WHQL_ML_Ver_1.0
- Installed LGUnitedMobileDriver_S4981MAN36AP22_ML_WHQL_Ver_3.6
- [patched]V20E_SEA.bin
- V20e_SEA.fls
And currently, my phone cannot boot into the main phone screen (it can only display LG logo at best). Please help!

Hi, thanks for your reply. Unfortunately, I haven't gotten to the point where the phone was rooted successfully (100%), whenever I tried to run B_SmartFlashTool_Extern.exe, it always ended up in error. What did I do wrong? I've used the appropriate files and installer, haven't I? Now, I'm totally freaked out because my phone has run out of battery and doesn't show any sign of charging even though I've connected the charger
Oh by the way, I've already used the patch rom for V20e, but still no avail and already tried running the program with admin rights

Question about root
Hi, I just root rights to V20O not only to root recovery, how to do it. Recovery mode without dissolving it.

Help Please! Phone in a power loop after ICS 3D LG Korean ROM Flash!

Anyone else having this issue? Procedure I followed was at "[ROM][ICS][P920] First ICS 4.0.4 Full 3D ROM Ported From SU760". Honestly, I'd really like to post this in the appropriate thread, but can't yet. I am experiencing the phone powering to the LG screen and off repeatedly upon plugging in a charger as well as hitting the power button. I had hoped it might just need juice but no dice. Does this really have anything to do with CWM? There is something about a modified USB cable in the original post that refers to a "screen issue" but there is no clarification to what issue. Here is my original post with a follow up:
Thanks!
OK maybe I should clarify

I do get the "S/W" screen with Korean text when I boot into download mode (if my terminology is correct i.e. up vol + power + connect usb cable to pc, then insert battery. How can I recover? Start over? How if I can't set connection settings on the device? ACK I have been at this far too long and must rest, hopefully with shiny new replies in the morning.
So to clarify, I had the ROM running fine. I was about to flash a zip, but was tired and had not loaded it onto the external SD. I am using the CWM referred to in the original post here:
"[ROM][ICS][P920] First ICS 4.0.4 Full 3D ROM Ported From SU760".
The app went through the motion but did not install anything, I assume. Then I hit "Boot to recovery." Could that have caused this? Now I get the LG screen and then no power, up to 3 times if I hold power. I am hesitant to follow any bootlooping procedure since I don't know if they apply to this phone and if that is the problem (it appears to be, but I am new to this. I WAS feeling nice that I was able to get ICS up and running). I cannot seemingly boot to recovery to reflash or downgrade. Also, when I connect to pc in download mode I get the Korean "S/W" screen with circular arrows and Korean text, but LG Flashtool does not connect. I recall hitting "Recover" in English during the original ROM flash. Please help!

I think it could be a bad ROM.
I assume that you can't boot to CWM/recovery mode and reflash a different ROM.
If I'm correct, I'd try to reinstall CWM via USB if possible...

Thanks for responding!
Someone IS out there...
I can't seem to boot the phone itself into CWM recovery no matter what. The phone was not left in debug mode, unfortunately. I am looking into using ADB to perform some kind of boot loop recover, but at this point am not confident in doing so. Any ideas here would be nice.
I see a boot loop recover guide on the forums, but it seems to assume I am able to boot the phone into CWM recover.
FYI I am not fluent in 'Android speak' but am getting there.
So if I am able to get a COM connection to the phone in download mode (which seems to be the case, as I mention with the S/W screen with circular arrows and Korean text- I do see a connection in Device Manager) is it possible then, to reinstall CWM as you mention? How? Would that, then, hopefully, revert it to a state where it is not, seemingly, attempting to implement some non-present process on booting?

OK Finally!
OK so NO one seemed to be able to help with my direct issue but I was able to at least reflash to the 'stock' Korean ICS port and get the phone up again. Ho Hum. Maybe I'll start an Android reflashing business. I will be trying AcidHazard mod to flash out all the bloatware. And DEFINITELY will be more careful with ClockworkMod.
This is what I did:
http://forum.xda-developers.com/showthread.php?t=1448803

Alright forget what I said about further flash for now
I was gonna try to flash in the Acid Hazard music rom which looks awesome, but the Prada CWM I installed (mentioned in the original xbsall ICS ROM installation procedure) once again caused a boot loop and I had to reflash the xbsall rom again. Until I see a CWM that I know will not cause this, I won't be booting into recovery. As I'd like to make a Nandroid backup, what is up with this CWM being a problem with my phone (ATT LG Thrill P925)? Anyone?

[Q] Did I BRICK mine? :( Please help me resurrect it from the dead!

Hi there,
First things first I'm a big noob when it comes to tweaking/flashing/anything with a phone; and life just confirmed it.
All I wanted was to make pics without shutter sound, to capture powerpoint screens in college instead of having to write ten sentences in 10 seconds. I couldnt just turn the shutter sound off! After some reading I thought I needed to both get my P880 rooted and needed CWM Recovery; I managed to do everything exactly as stated here:
Rooting:
http://theunlockr.com/2013/01/14/how-to-root-the-lg-optimus-4x-hd/
Installation of CWM Recovery:
http://theunlockr.com/2013/01/14/how-to-install-clockworkmod-recovery-on-the-lg-optimus-4x-hd/
After that I tried to install this rom via CWM Recovery -> install from SD/zip file -> CWM_deodex_rom_v10e_signed.zip
http://forum.xda-developers.com/showthread.php?t=1871858
I did that because this mod had the camera mod I wanted installed already.. The installation went fine, the phone stated.
But when I hit reboot, it got stuck in bootloop.. All I can do now is press PWR + Vol down (read that after some googling) and enter 'Android system recovery <3e>'.
It shows this list of options (above a picture of a dying android with a red exclamation mark on top of it)
reboot system now (done that few times now, gets stuck in bootloop everytime.. Well I think it's that. It gets stuck at the LG screen, it's my interpretation that that is the correct use of the word bootloop)
apply update from external storage (well please dear lord let there be an escape through this option)
wipe data/factory reset (no results after hard resetting, still bootloop)
wipe cache partition (did this too)
apply update from cache (not this, why whould I)
wipe nv partition (did this too)
Toggle Console VART Log (and well, I don't think this option's going to save me)
I wanted an option to turn off the shutter sound. Well, things changed. Right now I'm willing to do anything to get the phone back to life! Google couldn't really help me out.. Well better stated: I can't help myself out using google, so I'm asking for your help! Please all XDA tweakers, modders, hackers, etc. unite and help! It is appreciated A LOT! Please state what I need to do now, I just want to get it back to a working state. Or please confirm that it is not completely BRICKED ;x
edit: I followed some advice from the unbrick-thread http://forum.xda-developers.com/showthread.php?t=1843830
Now I'm stuck @ S/W Upgrade - Please wait while upgrading ... screen. Please help me out
edit 2: What I'm doing now.. via the LG PC Suite -> Lg Mobile Support Tool -> Recovery (you need to fill in either IMEI or S/N and model)
Status: Downloading the LG Mobile Phone Software Update program. Est time left: 44:40 for 400mb.. Nice server

Re-flash using LGFlash Tool.
Use compatible .dll depending if its v10x or v20a.
Search a little, there's a lot of info about that

Wait, my stock v10c's camera already had the function to mute the shutter sound. Why did you need to do anything else?

I managed to get my hands on the latest version of LGNPST - I suppose that's what you mean with LGFlash Tool.
But how do I know if the phone is v10x or v20a.. ? I think all methods to look that up are blocked, since Im in bootloop with only android system recovery <3e>
Thanks!

Many Problems with installing Cyanogenmod on LG Optimus 4X HD...

Hello everybody,
so I'm as new to this forum as I am to the android world. Just this Wednesday i bought a new LG Optimus 4X HD on amazon.de
Thought it would be nice to start of with Cyanogenmod.
So I started my search for some good "How-To's"...it were many I went through and I already invested many hours in getting this running. Sadly it still doesn't work. I actually wanted to stay with one How-To but at one point there's always a download not working so that other sources are needed.
So what did I do...
-I rooted it yes (at this point I needed to download "Rooting Toolkit for Optimus 4X HD" which wasn't downloadable so i switched to another How-To, btw. first How-To: http://androidlegend.com/android-4-2-1-via-cyanogenmod-10-1-for-lg-optimus-4x-hd-p880-cm10-1/
-Installed "LG 4X Recovery 1.2" and installed this way CWM.
-At another point here I installed ROM Manager, installed it and went into Recovery and here happend the first problem, kernel panic.
Said something like "couldn't load kernel/wrong kernel", kernel panics...Me panics too
Anyway, force kill -> auto reboot -> still kernel panic -> again -> batterie out and a few times with usb cable connected to PC -> Batterie again, works :good:
Ok so Clockworkmods Rom Manager seemed to be not that good... did recovery boot with LG 4X Recovery, tada works, I go into the folder with the Cyanogenmod-zip and want to start the ROM installation and it says Status 7 (of course I googled Status 7 and searched here in the xda-boards for it, nothing helpful found yet)
Installed older version of LG 4X Recovery (1.1), still same fault.
I uninstall the ROM manager, redownload and reinstall, try to backup -> Kernel panic.
I search for a different How-To, yet nothing good happened. Others go something similar and say "at booting press On-Button and Volume down-button at the same time", I do that -> Kernel panic
I have no idea whats wrong with the kernel...but normal booting works fine.
Next I read something about needing to unlock bootloader, have a workthrough aka this http://forum.xda-developers.com/showthread.php?t=2224020
After I enter "adb reboot oem-unlock" in DOS command window it should say something concerning "open bootloader", but not in my case, just a normal reboot happened (this is what it looks like at least). Checking the hidden menu also doesn't show anything as I don't have the option with the boot-loader status there.
Next trick, I go to LG Recovery again and first wipe the whole stuff and try then the Cyanogen istall, still doesn't work and as I wasn't able to backups before (tried Titanium but it froze at 12% and the stuff about ROM Manager is told^^) I now had a clean factory install, all my work before lost, nothing rooted and still a kernel which panics when I do the "safe-boot"(this volume- and on-button-thing).
I also tried 3-All-in-one solutions, neither of them worked. (2 german ones, and one english one)
So I think thats it, ah wrong, still not finished. I also tried to install a new kernel to erase that f****ng problem with the kernel panic. I choose to use WerwewolfJB_v005 http://forum.xda-developers.com/showthread.php?t=2256899
the easy and fast way made the same as the try before with the "open bootloader"-try, just normal restart. When I enter the second line in the command line, it just says "waiting for device".
So yeah, thats it. I don't know what else to do. Does anyone know what I could also do, or is this case unsolvable? Is the Smartphone broken or did I make a mistake at any point? What should I do?
I'd be super glad if anyone could help me here. I hope I described my case well enough. I hope I didn't forget anything.
Thanks in advance!

I am also new to this stuff but maybe i could help you anyway
What is the Firmware Version of your phone?
(Sorry for bad english )

The old "adb reboot oem-unlock" didn't work for me on UK, v234-000 either. I followed this thread instead and it worked perfectly first time.
As long as your phone has been turned on and connected to the network for long enough on v20x you should be fine - once you get the notification from LG about your phone being registered or similar then you'll be fine, normally a couple of hours.
Just reflash your phone to stock, wait for the notification and try the two-step method from the above post and you should be fine.

root , recorery and unlock boot loader
you must have your bootloader unlocked in order to flash kernels
( this worked for me but I can't guarantee it will work for others you can only try !! be aware when messing with firmware and bootloader you warranty could be voided )
make sure your phone is rooted you know if it is rooted because you will have superuser installed in your apps ( grey square icon with green android head on it ). if not I used this method to root my phone so try this http://forum.xda-developers.com/showthread.php?t=2180688
if your phone is rooted next you will need a recovery this will help to backup your phone and create a restore point so in case any thing goes wrong. to install a recovery go to play store and download rom manager ( clockworkmod ) once installed open rom manger and select recovery setup. then select install or update recovery then select your phone ( lg optimus 4x hd). then select flash clockworkmod recovery. and then wait while it downloads and setup . hopefully when finished it will say succesfull. ( make sure phone is rooted or it wont work ) to check clockwork mod is working you can reboot into recovery through rom manager or power off phone then hold volume down key press power button to power up but keep holding volume down key until recovery boot up. ( be a wise option to backup phone now in recovery)
next to unlock bootloader ( so you can flash roms with kernels) go to this thread, http://forum.xda-developers.com/showthread.php?t=2224020
and download the BL_unlock_new .rar file when its download copy it to your desktop on pc and then extract it to desktop on pc . now make sure your phone is not connected to your computer go to phone settings,then go to development options, and then select usb debugging on. once debugging is on now connect your phone to pc wait for it to connect you can keep your phone on charging mode. now open the BL_unlocking_new extracted folder on desktop on pc and double click on the BL_unlock file a box should open up on your desktop asking you to tap a key to continue so press a key now your phone should reboot and some white writing will appear on screen .on your desktop the bottom line should say please... now tap a key on computer it should say press any key to continue < waiting for device> now disconnect phone from computer look on phone screen it should say now ready! now hold power button for 10 secs and let phone reboot. to test if bootloader is unlocked on phone go to dail pad and dail this 3845#*880# you should get the hidden menu on your screen scroll down to bootloader unlock check and select then select bootloader unlock check and hopefully it should say unlock...
now you have root , recovery and bootloader unlock, now you can download a rom for this phone copy rom ( should be a zip file ) to your phone then open rom manager on phone and reboot in to recovery or power off phone, hold volume down button then press power button should now boot into recovery then you want to use volume keys to scroll down and select wipe data/factory reset with power button then scroll down and select advanced then scroll down and select wipe dalvik cache then you want to select go back then select install zip from sd card then select where you saved your rom sd card or external sd card then select rom then select install...
hopefully if that's helped you or anybody else ...

If the OP can possibly get his bootloader unlocked following the official method then he should, rather than using that file. Nobody really knows what all the 'fuses' that are blown by using that file do and that would certainly result in his warranty being voided in any country, whereas in a lot of countries his warranty won't actually be voided by using the official unlock method.

Ok, thanks for the answers so far. But still, wasn't able to get any further.
@Dexxon: Firmware version is 4.0.3
Besides: Kernel Version is 2.6.39.4 and there's also something written like "[email protected] #1" in the hidden menu...is this normal? AP Bootloader Verison unknown and AP OS Version is 2.6.39.4 also this jinwoo...
@SimonTS: I tried to unlock the bootloader with your link and advices (which is the same as i tried before).
Got a message saying "Thanks for buying this LG Phone..blabla" and I guess thats what you mentantioned about that informing.
Battery was loaded to 100% so i connected it to PC, said "LG Software Mode Connection" on the phone (before I always took that "data exchange connection"), went to the adb folder and made a command window there, entered "adb reboot-bootloader", smartphone reboots, should stay in LG window screen, but it doesn't. It just boots totally normal into the home screen.
@Hursty uk: As I said in the first post. Everything regarding the ROM Manager from CWM sends my Phone into kernel panic. As this is quite hard to get a normal reboot again (even battery out for some time and back-in doesn't solve this) I really prefere to not use this option. As it is just frustrating and doesn't help.
And yes it is already rooted (I have SuperSU and I checked it with the "Root Checker"-App) Everything says it is rooted. I rooted it with that method: androidlegend.com/how-to-root-lg-optimus-4x-hd-o4x-p880
Ah I really don't know what else to do. Is something just wrong with my device?
btw I also can't do a software update with the LG Software from there website, so I could at least go 4.1 instead of 4.0.3 atm...
When I try it that way, and install the USB-Drvier for LG P880 the SW-Update button stays grey and is unclickable even though the phone is connected.

To unlock the bootloader following either of the official methods requires you to be running v20x (The LG Stock v4.1 code) first, so that is why the commands are doing nothing for you.
For the moment, forget about CWM, Root, Bootloaders etc - the key thing is to get your phone working again. Can you reinstall stock v10x software following the guide on this page?

He might as well just flash JB with flashtool, saves him flashing ICS just to flash JB straight after

that would of been my next answer @SimonTS . A while back a flashed something on my phone and it got stuck at the lg bootup picture what I had to do was re-install original firmware ( through KDZ files) to get my phone working. I would try the link @SimonTS suggested .

Indeed - sorry, having a slightly dense day and was more thinking about getting him back to the stage at which his phone was working correctly before.

To unlock the bootloader following either of the official methods requires you to be running v20x (The LG Stock v4.1 code) first, so that is why the commands are doing nothing for you.
For the moment, forget about CWM, Root, Bootloaders etc - the key thing is to get your phone working again. Can you reinstall stock v10x software following the guide on this page?

Thanks for that link, I tried it but that also didn't work (at least I guess so...)
I did everything like said at the link but at the last point the program (kdz_fw_upd.exe) crashes. Tried it 3 times, every time as administrator like mentioned in that forum post. I'm using Win 8 64bit btw...
Screenshot is in the attached .jpg. My system is japanese, but I think you can figure out what this kind of window means. It just says that the program isn't responding and needs to be shutdown.
I tried it like mentioned with putting the battery back in when the log starts and without putting it back in, in both cases the program crashes after a few seconds (~10 secs) when started.
Where do I actually see which V**x version is installed? If v10x or v20a? Surprisingly the LG Support Tool said I have v10H when the phone was still connected after the crash. And it offered me a SW-Update. But I haven't done that one yet, not sure if that would work correct...

@ chrisus
man, what is your phone status now?
in what situation you are actually?

+1 this. Also, there have been many problems with running these apps using Windows 8, and you need to make sure you're not using a USB 3 port as they being other problems in to the equation.

Ok so I've flashed JB with the LG Updater (without batterie and volume down button pressed connecting to PC, than start the update -> meanwhile putting batterie back in)
JB worked just fine and I also don't had the problem with the kernel panic when booting with volume down and power button.
So I thought, everything fresh and also different, I might give the ROM Manager App again a try (after I rooted it that way: http://forum.xda-developers.com/showthread.php?t=2180688 )...well, wasn't that smart. After I installed the Recovery for P880 in the ROM Manager, i made a normal boot (just for sure), back in the app, i wanted to go into Recovery mode and again kernel panic, bit different this time cause it does a shutdown after 5 seconds^^
Anyway, this way it didn't work, from now on I also couldn't go into safe mode anymore, same kernel panic.
As this kind of recovery doesn't seem to work, I tried the "old" way with the "LG 4X Recovery" I mentioned before. After recovery installation i just wanted to boot normal aaaand nothing happened. It stayed in the LG screen. Restart and anything didn't help here so I backed back to v10H with previous methods. Now I just got a security error saying "morning call is empty", no idea what that means but I just did the same method for JB again.
Worked afterwards, so I wanted to try it without ROM Manager Recovery installed and just LG 4X Recovery, (after rooted again of course) and it didn't boot again. Same game again.
So now I have JB installed, I'm going to root it now again, but I don't know what way I should go for doing the Recovery Part. I'm stuck on point 3 here
Any advices? btw thanks a lot until here, at least I made it half-way-through to JB now. Worst case I'd stay with that one at least.

I'm not entirely sure which threads you've been reading. Once you have the stock v20x ROM on your phone, just leave it alone for a few hours and make sure it is fully charged
After that, try to unlock the bootloader before doing anything else. If that works then you can worry about CWM and custom ROMs.

ok.
now i suppose you have a functional rooted JB 4.1.2 device.
from that you have to going on to rest of the steps to have CM installed on your device.so if it is not that (functional rooted JB device) is need to flash again JB and rooted again.
if you have the proper kdz file the tutorial for flasing is there: http://forum.xda-developers.com/showthread.php?t=2069723
and the tutorial for rooting device is there: http://forum.xda-developers.com/showthread.php?t=2180688&highlight=root+jb+4+1+2+
after that make some reboot of device to verify that:
1. the device boot to system normaly a few times (just let the device boot itself)
2. the device enter in S/W Upgrade Mode (with the device off, put the USB cable in device and PC or in device and AC adapter and press VOL DOWN + POWER) a few times
3. the device boot in Stock Recovery (with the device off, press VOL DOWN + POWER) a few time.
if you can manage to do this tree steps a few times normaly then you have a fully functional device and we go to next step that is Custom Recovery
the chance to make this steps without errors is more big if you start from scratch meaning fully wipe the device and flashing stock LG software on the device.
so, let as know here when you are ready...

he should unlock bootloader before flashing custom recovery.
so, dont use rom manager before you unlock bootloader, that's why you get kernel panics.

[Q] LG Optimus 2x stuck after flashing

Hi,
I’m trying to upgrade my Wind Mobile Optimux 2x from 2.2 to Android 4.2.2 (CyanogenMod Nightlies). The Clockworkmod identifies my phone as LG G2X; I tried to manually select Optimus 2x but flash recovery failed. I kept it as LG G2X but each time that I tried to flash with a P990 ROM (Optimux 2x), it was unsuccessful and I had to factory reset it by pressing Power and volume down key.
This time, I selected P999 ROM (LG G2X) as I read that it’s the same as Optimus 2x for T-Mobile...but now it stuck at the LG logo (with blue/purple background lines) and pressing Power and down key doesn’t work anymore and it stops at logo again instead of resetting.
If I hold the volume down key until second LG screen, it shows: S/W Upgrade Please wait while upgrading... and it stops there forever...
What should I do to resolve the problem? And is there a way to go back to factory setup mode?
Thanks

First of all, check the sticker under your battery for whether your phone P990 or not. Please let me know what type of phone do you have P999 or P990

It's P999. I spend several hours to research about it and tried different applications...One-Click-G2x-recovery-flasher-04-28-12 and CWM_5.0.2.8_P999 cannot flash the device and give the partition download fail error, maybe because I previously used AIO-P990-ToolKit_v5.6 to nvflash it as APX drivers are installed and USB cable is working well. I tried different custom recovery versions using AIO, ICS-cwm-6.0.3.1, ICS-cwm-6.0.2.5 (before knowing that I have to use G2X), ICS-cwm-5.0.2.8e and ICS-cwm-5.0.2.0 but was not able to flash it as it goes back to recovery mode after rebooting, instead of running the new O/S.

I can do for you a nvflash for your p999. It will recreat all partitions and etc and will flash cwm p999 recovery to your device. Search custom roms on the optimus g2x forums. It will take some time since i have to download a stock p999 rom and gather the necessary files
Download my attachment and run flash.bat. It repartitionate your phone to p999 layout and flash cwm as well. Do not flash p990 custom roms with cwm to your phone, because p990 and p999 partition layout is different.

Thank you for your reply. I finally could flash it using G2XCleanUpBatch5028. It turned out that CM7 unlike what I thought is 2.3.7 not 4.x and I already found some problems in it...I'm trying to find the original Wind Mobile ROM and a way to install it back on my phone to keep it as my factory reset backup to return back to it in case that I could not find a reliable custom ROM.
By the way, I'm wondering what's the difference between your attachment and the one (G2X_V21E_00_NVFlash) that comes with 450MB ext3_system.img file?

My version of nvflash I skipped the system image, because I assumed that you are going to flash a custom rom. So that 445 mb differnce is teh missing android OS.
You can find your original rom at http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=0000000000000000 , replace the zeroes with your IMEI number. It will give you the download link for your current stock rom. It is in kdz format. If you having troubles flashing kdz, then give me the link to your kdz and I am going to make you a nvflash rom from that.
