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

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.

edited last post with a warning you could void warranty !!
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.

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...

man, what is your phone status now?

+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.

You couldn't go to S/W mode? Charge to full, battery out and in and then volume - and powerbutton? There my knowledge ends, sorry Next time read instruction.

Did you try to hold the - key down while plugging in a usb? (pull out your battery) if that succeeds then you should use kdz flash tool to revert and AIO Tool by OS_Hacking to get a proper recovery.
Hi Experts
My Optimus 4X HD (jelly bean) has been rooted and boot loader unlocked successfully. CWM touch recovery is also installed and I was all set to flash cyanogenmod ROM 10.1.2.
My device is stuck at the LG splash screen after I selected normal boot from the 4X Touch Recovery app.
When I try to enter recovery mode using Volume + and Power button, get the warning message from LG; "This mode is for data backup at service center..." and does not allow further. In short I am not able to boot in any mode.
Is there a way to bypass the warning message from LG and enter recovery mode.
I have checked ADB is working fine once I power up and connect via USB. I can see the device in ADB Devices command.
I am also able to enter another console (volume - and power button) but there is no recovery option. Just data reset and wipe cache partition etc are available.
Is there a way to enter recovery mode and flash recovery image or flash ROM from ADB
Please advise.
Thanks
Soumya
Touch recovery app is for ice cream sandwich, you needed to install proper recovery from ROM manager or manually. Reflash your stock image then do your homework

I am trying out various ways to get the stock image installed . Tried from KDZ file, LG Mobile support etc. All have failed so far.I'm Still trying.
Is there a way to skip the LG service warning. I guess the service center folks must be using some way to bypass that warning.
The warning says "This mode is for data backup at service center, please remove battery and place again abd then use power button....."
Somehow this has affected my 32 gig SD card which is unreadable now. That had all the recovery images etc, will try to use another one. The sd card is simply unusable now. :crying:

you're doing it wrong - don't use volume up and power. just hold volume down while plugging in the cell phone into computer (no need to press power button at all).
this way you'll go into s/w upgrade mode, where you can use kdz flasher to flash 20a kdz file.

This forum is for the LG Optimus 4X HD. We use completely different methods to root and unlock our device, so don't expect to get any help here. Also, you should never just post your stuff onto the end of someone else's thread unless you are posting about the same thing - it's very rude.

No one here can help, completely diferent device. Youu need to post in the forum specific to your phone if you cant find it post and the general android forum. Asking for advice on a device forum different to your device is a sure way to end up with a brick
This is place where you can ask such question @akshay aks

Sadly, you are not alone with this problem. My experience was similar to yours. I solved it by throwing the phone away and buying another. Unfortunately, my second P7 has faulty flash memory and is almost useless. I'm now awaiting the delivery of my third P7. I suggest you buy another and avoid EMUI 3.0. Good luck!

A question? How can you do factory reset through settings when you have a bricked phone? I find this very strange!
If by any chance you still can load the OS, get the quickboot app in the market. It will get you to fastboot and than maybe you can install recovery.
All in all, I still don't understand, is your device bricked (can't load OS, just constant reboots - loops), or you just can' downgrade to EMUI 2.3!
Good luck

Thanks !

To install quickboot you need to load OS which you apparently cannot at the moment. Did you try this: http://forum.xda-developers.com/ascend-p7/help/stock-recovery-stuck-bootloop-t2875935

I totally bricked the phone ... i wrote in fastboot "fastboot flash boot boot.img" and after that the ph0ne begin to restart in timeless circle .. and still do it ... please help emergency ))
Try the method on the first post: http://forum.xda-developers.com/ascend-p7/general/reverting-emui-3-0-to-2-3-t2934277
I fix it ... turned out i was installed wrong boot.img .. may be of huawei p6 and the stock recovery which installed doesnt work .. now instaled working and everything is ok Thanks 4 wish to help me !
I have a similar/the same issue as some people above described.
I reverted from CWM recovery to stock recovery (same stock recovery img as I used before succesfully). Now the phone can only boot to stock recovery (Reboot system now, Wipe data, Wipe cache, are the only options.
The phone is not detected by adb on that screen, so I can't try to reboot to bootloader using ADB. I also can't get into bootloader from volume button + power, because the phone boots immediately to recovery after I turn it off.
Fortunately I managed to solve it, so for reference:
Remove SD card
Place full (no incremental update) update.APP file on external sd card in /dload folder (B609: https://mega.co.nz/#!akcBCZBJ!4jLhlNsH54H-3DHeK3xPkzT3fWIHBR6QtbOllubdz5Q) using a different device (computer)
insert SD card
turn the phone off from the recovery loop by holding all three buttons (VOL+POW) at the same time. It's a bit tricky, but keep trying until the phone is off
Insert the USB cable in your phone and connect it with your computer (haven't tested if it simply needs power, or an ADB enabled computer)
Then immediately press all three buttons again
You should enter recovery again now, but the phone will immediately start flashing the update.APP ROM.
You will lose all user data though!
same problem here
Hello to all,
I had the same problem that my phone doesn't go on and time after time boot fails,
i read this solution and it works great i am updating my phone.
only i take the power + vol down and when the logo came switch vol down to vol up.
thx for youre help and sorry for my bad english
