[help] - LG Optimus 4X HD

hello !
I'm a in trouble with my friend's Optimus 4X HD.
We tried to install CWM but i made a mistake. i instaled the apk of the recovery but since this, the phone juste dont boot up. The LG logo just blink over and over ...
We still can acces the stock recovery (tried wipes but did nothing). And we also can get acces to the download mod (strangely only withe the battery in the phone. if it is out the screen display stranges colors ... )
We tried to fix it following tutorials showing how to flash a .kdz but all the softwares shown just crash.
If you have any idea ...
Thanks a lot ! And sorry for my english :s

Force an update using the LGMobileSupport tool while in download mode. The option is in the upper right menu's. That should bring the device back to life.
On why you got in a boot loop: you tried to flash a custom recovery without unlocking the bootloader. Please read a little more before you try again.

hey guys, thank you for your answers
we already tried to follow the tutorial you sent sonyc2011, but i dont understant why, most of the softwares we are supposed to use just crashes.
But we found an other tutorial (type : "How to Return / Unbrick / Downgrade LG Optimus 4X HD" to find it) that worked perfectly !
So we installed the old ICS rom, we updated it to 4.1.2, then rooted it. now we are working on unlocking the bootloader. And we will THEN install the recovery .
Thank you again for your help and sorry again for my bad english !

[Q] how to remove clockword mod recovery

Hi all
This problem that I have is pissing me off so much. I rooted my phone and then unrooted it, and then my Android Market icon was missing. Now, whenever I want to do a factory reset, the phone goes back to ClockworkMod Recovery every single time. I want to get rid of this CMR. Also, I've tried to stock original rom on my phone but it does not work at all. What is happening? My phone is LG Optimus 2x P990. But I always get this error where I can't apply the DLL file. This really annoying me right now. I've tried everything and NOTHING works. I regret rooting my device.
Please help me thanksss

You can flash the original image using SmartFlash.
Get your original Firmware image from here. The instructions for SmartFlash are here
how to flash the zip
sorry I am completely new to this. How do I apply the zip? Do I boot into recovery mode and install zip from there? I have done this with other zip files before and it always ended with:
'installation aborted'
im trying it now, but its stuck at:
'Restoring stock recovery image'
smart flash
smart flash doesn't work for me. I always get this time out error.. I really don't know what to do now. The recovery stock file did install but then I chose 'reboot system now' in CWM and it got stuck with the LG logo. Now, it's back to ClockWork Recovery Mod again!! i don't understand. Please help.. Many thnks
what type of error?
your device-manager on your pc recognizes your 2x, when you connect it as described in the instructions?
THis is the error:
00:00.0 Sec ownload Start...
00:07.5 Sec :We can't communicate with specific port
and now, I can't start my phone. It gets stuck on LG logo. I tried the remove CWM method, it worked but when I rebooted my phone, my phone would not start at all. P. Please help.
yep it recognises it but it always gets this time out error... what should I do? Please help.. Many thanxx
Does the COM port get detected automatically when you plugin the phone ?

Same with me. Go on trying at some point it will work. It happens with me everytime i flash with smartflash. Myself also waiting for a definite solution to this problem. i think the problem lies with usb drivers. I also tried with taking out card and sim but cannot pinpoint the problem. Any successful flasher may upload the drivers. Moreover i also disabled programmes like antivirus etc running in background. Waiting for a more definite problemfree flashing solution.
I think, install drivers to smartflash, no other drivers, and later smartflash.

[Q] [HELP] Bricked my OB and the tutorial is not working.

Hey guys, can you help me out? :/
I was using shootme (or a diferent app to record the screen, dont remember the name), and than all became black.. tried to reboot, but it was bootlooping.
Than i tried to use the emergency recovery tool on LGMobile Update, but with no success.. Tried this (http://forum.xda-developers.com/showthread.php?t=1275315) tutorial, but when it comes to the R&D Test Tool do its job, it doesnt recognizes the phone (even after i install all drivers possible).
With no hope, i have flashed this v20a (http://forum.xda-developers.com/showthread.php?t=1310093) and i'm stuck on there.
Can you tell me what i should do to flash CM again? Or NOVA, seems to be more stable for me.
Thanks

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

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

key volume + and usb plugged
or use r&dtt method => http://forum.xda-developers.com/showthread.php?t=1111771
Ok, I'm totally freaked out now. I can't even start the S/W update mode anymore although I've been charging the phone for about 15 minutes. No, I don't know how to use r&dtt method, tried to read the post but I don't which one is r&dtt method. Can you help me? I've checked the charger and it felt warm after 15 minutes of charging though

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

[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!
nvm: just found this thread http://forum.xda-developers.com/showthread.php?t=1861854, found out that you are an awesome guy!
just flashed to v20a, she's back alive

bricked: LG optimus 4X HD / P880 won`t boot (boot loop)

Hi,
i had CM 10 on my phone. But i wanted to go back to the stock rom, so i flashed the kdz (v20B_00). After finishing that, the LG P880 restarted, but it stuck at the LG sign. I don´t know what to do right now.
Information:
- The bootloader is unlocked
- before I flashed the stock i had root access ( not sure if I still have root access after flashing)
- I tried to flash with several times but it didn´t help
- I can still put the phone into S/W mode
- if i hold volume down and power I can choose between some tasks like rebbot system, but if I choose one, the phone won´t do that. Instead it only shows me the Android-guy and a red triangle
I am frustrated now and I am really hoping that someone can help me now.
(sorry if there are any grammar / spelling faults because my English isn´t too good )

Which system did you use to flash .kdz? (Some people have driver problems with Win8+)
What happened after your try to flash failed? (screenshot, informations?)
As long as you are able to put your phone in S/W mode there's still hope
