Have you tried booting into recovery? Power+volume down...

Did you try to boot without the SD card? It helped me once.

Assuming you are running a custom recovery image, go to it via the bootloader menu (Turn phone on while holding volume down, then navigate to recovery using the volume buttons and selecting recovery using the power button). You should then be able to flash the same ROM you currently have installed. If however this is a completely stock device then you could run PASSIMG.zip via the bootloader to save your current install. If you need more info just ask

i cant able to access recovery mode

how to wipe??
where is wipe option...let me tell u that i cant able to access recovery menu ..without recovery menu i cant wipe or flash the phone??
is that true?

If you can flash a rom use 2.1.1 not 2.1. Assume you are doing that thru fastboot from pc.
Also, try the 3 finger reboot to get to recovery.
Hold down pwr/vol-/trackball at sametime until phone boots into bootloader, then navigate to recovery option. Then wipe all and restore a good bu. If this happened while dl'ing apps, one may be bad. Get all of them off phone and do one at a time.

Ok, understand now.
You may have some options thru fastboot and the pc. Do you have SDK installed on pc. I am not good at that, someone else may have suggestions along those lines. Unless, as I asked, you already have used that method to flash amon ra 2.1.
If you can thru fastbboot with SDK I would still flash amon 2.1.1

help me

I am out of ideas, sorry
Someone will get you going
Sounds like you are using SDK, it may be the way to wipe and get back to an original phone state, then reupgrade. I don't know sdk very well.
Did you try the other idea of trying to get to recovery with sd card out of phone. If you do that you may want to back it up while out of phone if you have a sd card reader
Good Luck and wait for more help

Why does this thread say solved??
Just restore a stock image.
Follow the wiki guide for unroot/restore. Use the passimg method, with the FRG33 zip, which can be found by following the link on the word "here" on step 2...

Thanks for your input DR
The back to stock and passimage was where I was thinking he needed to go. But, know nothing about doing that without a lot of research of my own.
Anyway glad he got it--what did he do to fix
ken

Looks like he did exactly what I posted. Funny thing was, it was a thread on another forum, where I had suggested the same thing to someone else, and he'd picked up the trail... xD

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?

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...

+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.

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.

Cannot get into recovery

I have a LG Thrill that is stock ICS. If I boot the phone and check all the buttons the buttons work, however when I try to boot into recovery the phone just boots or turns off. I hold the 3d and volume down button then push the power button until a vibration and lg logo then release the power button. I've tried to go thru adb to reboot into recovery but I cannot see the device in adb.

Have you actually installed cwm recovery?

No, I'd love to be able to install CMW or TWRP but the guides I have found all say that I need to be able to boot into recovery.

You can install CWM (or TWRP) by flashing it with Fastboot, but you will need to place a recovery image file named "cwm.img" in the CWM folder in the Fastboot pack. Some available packs (check the Optimus 3D dev section, same device, Euro flavor) have the image files already included, I think.
The method I have mostly used is to flash xbsall's rooted ICS with recovery.
http://forum.xda-developers.com/showthread.php?t=2195753
His rooted ICS uses a type of recovery that is in system partition (not recovery partition). So if you want that, or you do not want to flash your device, use Fastboot (or one of the customized variants)

First, thanks for the help. I now have superuser available and couldn't be happier. The reason I decided to do this was that I couldn't get the wifi to switch on and even with the super user access it won't. Should I assume that this is a problem with the phone or is this something that would work if I were to roll back to gingerbread?

It's most likely a problem with the ROM/kernel you're using. I'd switch to another.

I can't say thanks enough for holding my hand so far. Is there a good guide that you would recommend for me to look at. Some of the ones I've viewed here have different information for each of them. Is the reason that thus phone is so different from what I'm used to due to the omap processor?
Sent from my SGH-I727 using Tapatalk

I had the wifi problem a while back; it was due to me installing a custom ROM without doing required wipes in recovery before installing it. Not sure how you got to ICS, but if you follow the guide I linked above it should solve your problem. You don't have to install the custom ROM if you don't want. Just stop after installing rooted ICS. Be advised that driver install for pc is fiddly, hence the detailed install instructions.

Can anyonne throw me a line here. When I install the omap drivers for the phone (step f4.1-4.5) the phone still keeps disappearing from the device drivers. Even disconnecting and reconnecting with the volume up button pressed isn't helping. Any ideas? I've tried uninstalling all of the drivers, using system restore to roll back, different cables. It used to work, now it doesn't any ideas?

If you mean the way it keeps blinking on and off, be ready with the mouse. Watch for when it appears and quickly right click on it, you kind of have to catch it. Then point it to the driver in the Fastboot folder (not the one in the omap4flash installer folder) as described. Once that is done you unplug phone, then replug, volume up, and let the two LG drivers install. All LG stuff on pc should be uninstalled and pc rebooted before beginning with all this. Also, some antivirus software can mistake the driver as being malicious and delete it when unraring the Fastboot folder, without it notifying you. And if you have a custom bootloader on your phone you may need to skip running omap4flash installer; they seem to not agree somehow.

error boot image signature means the bootloader is locked. so u didnt install the recovery and so thats why u cant go in recovery. u just deleted the stock recovery by mistake. now u either go ahead and try unlock , flash recovery and install new rom if u want to go away from stock rom, or use kdz to restore.
<<EDIT>> i dont understand that o4x. i just told you whats ur situation there. now use search and find the solution

Hi there,
I was recently put in the same situation, i.e. I installed ROM Manager and then ClockworkMod. When I open ROM Manager --> Recovery Setup --> Install or Update Recovery --> Click on "ClockworkMod Recovery" --> I get "Error while downloading from server. Please make sure that you have a stable internet connection and that your SD card is inserted and have free space!". I have made sure that I have both, therefore I do not understand why I get this error. When I select "Reboot into recovery" in ROM Manager my phone restarts and then I get the same error as ruznik.
When I try to boot into recovery manually, i.e. switch off phone, Volume UP (or DOWN) + Power button, I get the same error as ruznik. However, my phone boots normally which is always a relief.
I uninstalled ROM Manager and tried to boot into recovery and I got the same error as ruznik. Then I installed back ROM Manager and in the Recovery set up there is already "ClockworkMod recovery", which probably means that ClockworkMod was not uninstalled when I uninstalled ROM Manager.
I have rooted my LG P880, but I believe I have not unlocked the bootloader (I suspect that CWM + bootloader not unlocked is what is causing the error with booting into recovery?). I say I believe, because I did the rooting some time ago and I do not remember if I have unlocked the bootloader as well.
I would like to uninstall CMW. However, I understand that this is not a very easy thing, therefore I would be happy to reflash my EUR-XXX Jelly Bean 4.1.2, root and then unlock the bootloader. However, although I have properly installed the drivers (as this is not the first time I will flash the EUR-XXX), my phone does not connect to my PC, although it charges from the PC. I have tried with two different cables, I have enabled debugging, I have Media Sync enabled (I tried also the option LG software as I have LG PC suite installed), I have tried to connect it to different ports, I have tried to connect it to different PCs, but still nothing. Note that this is happening only with my LG P880, because I can connect properly my Iphone 4S to all 3 PCs. Also, when I open my LG PC suite, I cannot connect the mobile phone to the LG PC suite via cable, but I can connect it via Wifi connection.
I am a bit reluctant to unlock the bootloader, e.g.
youtubedotcomslashwatch?v=sBeirPeT2rQ
youtubedotcomslashwatch?v=iqEop-ThNug
because I do not want to brick my working phone when I cannot connect it to my PC so that I can flash it (sorry for the broken links - I am not allowed to post links because I am new to XDA). Therefore, I have two questions:
1) Is there anything I can do to connect my phone to a PC? I believe that everything went wrong after I installed ROM Manager and then CWM via ROM Manager.
2) Is it safe to unlock the bootloader while the phone is in the current state? I am not sure if the phone will restart and then will not be able to turn on again because it will be bricked? And since I have not managed to connect my phone to a PC, I am not sure how I will be able to flash the software?
Apologies for long email - I tried to be as descriptive as I can. Thank you in advance for any suggestions.

[Q] Rooted 4x hd doesnt boot into CWM (or any other recovery)

Hello together,
i used search and the suggested topics but i cannot see the same problem as i have.
Recently i rooted my 4x hd with success (i used Kingo Android Root, as i found here in the forums) because i want to install Cyanogen Mod, installed Rom Manager and downloaded the CWM Recovery (not the touch one, the lates it can find, 6.# or something was it) through that. Then it got installed and finished without error. Of course i gave Super SU right to Rom Manager. Its shown as installed in Rom Manager too.
So the problem starts when i want to boot into the CWM, no matter wich way (through volume down + power or in Rom Manager with the "boot into CWM" option. When i try this all i get is 2 lines in minimal red font on a black screen. I forgot was was written there but it was really hard to come out of that. Finally the phone booted normally. I tried it 2 more times, with same results. I also re-isntalled the CWM over the Rom Manager, it just stays like this.
Whats wrong?

You did unlock your bootloader, didn't you?
If not your bootloader gets screwed and you have to reflash kdz (search for tutorials).
You can't boot into cwm because if the BL is locked, you don't have the permission to change recovery/rom
(not actually permissions I think but easier to describe it that way).
So the recovery is now corrupt and there's no way beside the one I already mentioned
(you can try to unlock your BL but I don't know if it's possible in your state.

Thanks for the fast answer. Makes sense,
In the tutotial i followed that time was unlocking bootloader not mentioned, i didnt do this by hand, no. Honestly i thought this will be done by the root tool.
Edit: found your answer to that, sorry.
Anyway, so can i still do this now or did the bootloader got already srewed on first try when accessing CWM?

Sorry I was a bit incorrect. The bootloader should be fine (at least when you reflash kdz as the stock recovery will get flashed as well). After that you can unlock your boot loader and flash any custom ROM.

Thanks.
I did it in another way, i think it solved it too (probably its doing the same...). I downloaded the LG Support Tool from website and used the Option "Repair Upgrade-Errors/ Behebe die Update-Fehler" without to really know what happens (hehe) and it seems to reflashed some important things, without to wipe any data though. Anyway, the root is gone now but i can go into the LG Recovery at least.
What bugs me a bit is the question if this LG recovery is the standard or if theres still a problem? Because the "recovery" i mean is only a picture with an LG Logo and something like "LG Recovery Mode -- Service Center. After put out and re-insert battery use the power button to keep using the phone."
Is this the real recovery? I had a lot of phones but never saw a recovery like this...
