PLEASE HELP!!
SOLUTION:
Reflash .kdz via Software Upgrade Mode (hold Power button and Volume - )
Dude, reflashing your phone should work. As long as SW mode is still accessible, your phone isn't dead yet. Follow the instructions on this post http://forum.xda-developers.com/showthread.php?p=35971349 Be freaking sure all necessary drivers are properly installed.
Or you can put your phone in recovery mode (power + vol +) and reinstall the stock rom using recovery LG tools providing your Internet connection is fast and stable

hey dude, i have flashed 7 times exactly since this morning only. and i have gotten that error 3 times of those 7. so it should not be a problem
Thanks!
After a few attempts, was able to go to the s/w upgrade mode.. (power + vol(-) )
Reflashed .kdz and it's all good.. (had to root again)
Actually, i was freaked out more coz it's my new phone and i didn't find others with the problem..
I hope that this thread would help if anyone faces a similar problem in the future..
Thanks for the prompt response, guys!

You needed to unlock bootloader first, either "adb reboot oem-unlock" or download terminal emulator, root the phone and type:
su
echo 40000000c8 > /sys/firmware/fuse/odm_reserved

I solved the problem flashing back to stock rom.
From this page http://lg-phone-firmware.com/ you may download your original stock rom.

And once again:
flashing stock is not at all dangerous. it will not brick your device or something else.
Sometimes you even have to re-stock your phone.

you installed cwm without unlocking bootloader. re-flash 20a/20b (jellybean 4.1.2) kdz, then unlock your bootloader, then install any custom recovery you want/need
Have i go bak to JB anytime?

Bootloader unlocking is only available if you're on JB. If your boot image is faulty you need to revert back to official JB.

German here too
So if I understood you right, you tried to install CWM without unlocking your boot loader? So now you got a boot image error? I'd suggest to try LG Mobile Support Tool and flash V20A/V20B and then unlock Boot loader. Even if you're on "official JB" as of now, installing CWM without unlocked bootloader screwed your boot image and there's no way to do anything without flashing back a kdz.

Hey,
I have tried to do the Update to the Firmware by LG Mobile Support Tool but there is a Error every try. I have tried it about ten times but the Update fails every time. What can I do now? :/
There is no Error Code or something.
Can help a factory reset there?
Or should i falsh the Original Recovery with the All-in-One toolkit?

Wait...
You just rooted, but didn't unlock the bootloader? If you want to install CWM on this device you HAVE to unlock the bootloader first!
And do you see the 1st bootlogo (not moving one) or the 2nd bootlogo (this logo is moving)?
Try to pull out your battery for at least 10 seconds, then plug it in again and start flashing a new KDZ, I guess there will be no other way, since the recovery will be corrupt...
Do you see two red lines at top . If so your bootloader is locked and don't allow cwm recovery to work Try use power + vol up while phone connected to pc it should get you to so called recovery mode from there try reboot and it should work then you have to unlock bootloader to get cwm recovery to work
Another thing I didn't try myself but installing cwm recovery is replacing file dev/block/mmcblk0p1
Maybe if you have the original file copy it over there return you back to stock recovery

please search in the general forum for p880. it's stickied.
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?

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 .

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.
I have root and unlocked bootloader. I did an update of lg and thereafter blocked, do not know if this was the problem.
Install the CWM by room (room enox iodak08 +), I can enter the bootloader, installing, when reboot the sistem entering the boot but does not start with the system and back to CWM after being taken. I can not get into the room and I can get into CWM. I've done factory reset and wipecache, I returned instal to the room, and nothing, enters the boot but does not start with the room.
I'm in a tricky situation, I stopped to have a mobile phone and I stick one paperweights. Need a little help.

Install or reinstall latest drivers from LG and try again when it does'nt work change usb port or try it on other PC.
Good Luck..
as I am in CWM recovery, removed the sd card and put a room.zip and flash. Did the installation but when "reboot sistem" back to cwm recovery.
The problem is that the Phone was locked into CWM recovery. And I have no way to recognize the phone on PC. Is there any way to unlock the CWM recovery v6.0.4.5?

no. boot into s/w mode and flash kdz. there are plenty of guides. if your pc cant detect your phone while it's in s/w mode, then reinstall drivers

It has been stated time and time again that your must NEVER carry out a vendor OTA on a rooted or modified device. It causes a problem 90% of the time as the OTA has no flexibility to deal with something it isn't expecting to find - so you get exactly what you have.
Just be thankful that it is almost impossible to hard-brick our device or you really would have a paperweight. Instead you just need to search and read a little to get it back up and running.

You need to get your PC to recognise the phone, thats the first step in this repair (unless the usb port is broken, there's no reason why it wont recognise, whats your OS and version, usb 2 or 3?)
why not put cm10.1 on a microsd and flash it from there?

it still won't work, after upgrading it ota while having custom recovery installed, a person will be locked to recovery for some reason (atleast other people were). the only way to fix it that i know of is to reflash a kdz

cmon, pay some attention you don't need to turn on the phone, or boot into the system itself to boot into s/w mode. now, there are tons (like 3 or 4 guides, plus many other topics opened by people with exact same problem like you) threads that tell you what to do (hint: figure out how to boot into s/w mode), so i'll let you search around for the guide.
I suggest using this method: http://forum.xda-developers.com/showthread.php?t=2682146
It's easier, faster and safer than flashing a .kdz file. (Plus, it tells you how to get into the s/w upgrade mode!)
Greetings from my Nexus 7 FHD!

I think this method also flashes a kdz, but does it automatically for you. But yeah, this one is easier than manually flashing. Thanks for posting it
Also, thiy method will format internal sd card. My suggestion is to do a data/system format from cwm before you go in to flashing a kdz, either manually or automatically, so you don't end up with formatted internal sd card
A big thanks to SimonTS, JoinTheRealms, Flying_Bear and balloon27. This is a fantastic forum and you guys are spectacular. Due to professional reasons only going back to the forum after seven days, I go to the sea and I'm without net. Got this getaway just to thank you for the care provided, the mobile phone is the same and will just touch it after a week. Once again, thank you very much.
I just make the process advised by balloon27 (http://forum.xda-developers.com/show....php?t=2682146). I have my 4X hd back .... yupi, yupi, yupi, yupi, yupi, ..... you guys are just the greatest. Once again a big thank you all of you. The 4X HD is working like a charm, a thank-you to the forum.

Solution
Above post is mine.
I was stuck at LG Logo for 2 whole days.
You have to flash your phone.
I flashed my phone with same v20a (4.1.2 JB) firmware.
now its working absolutely fine.
Download LG Flash tool
Download Firmware.
pull battery out, Put it back in,
hold VOL- and Connect usb cable
then your phone will be in S\W mode.
then run Flash tool and select Firmware file,
and flash it.
your phone will restart automatically, then pull out cable and let it start on its own.
DONE.!
for LG Flash tool and Original V20A firmwares google and search.
as I am new member I am not allowed to post links or else i would have posted all the new links.
Its easy, all the best..!
so no hope for me?
can't flash KDZ, it just dosen't work, or freezes, or app stop responding and force-closes, when flashing by flashtool it errors after 17 sec...
any ideas?
LG service center
Hi again friends.Unfortunately I'm going to use lg service center and show phone to them:crying:.What should I say to them?Can I use warranty?Do they realise I rooted my phone and my warranty voided?And finally if warranty doesn't support it, how much it costs to repair?
