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.

Dear all,
Last night I tried updating to V20N (Dutch) using the standard LG Mobile update tool, so via USB. After the downloading step, the update tool proceeded to install until 15% has reached. The tool says "communication error between PC and phone" or something like that. It tells to disconnect USB and remove battery and try again. I did this 4 times, but the phone itself stays in "S/W update" mode.
Before perfoming a hard reset (and losing all of my data) using one the unbrick tools, I solved this by using the option "recovery and emergency" in the options tab of the LG update tool. After 20 min recovery my phone was back and guess what? It had been updated to V20N 2.3.4
Now it feels more snappy, no more lag while sliding the screens. Apps running smooth. No idea about the battery life.
Same issue here can u please explain it further or a step by step guide.

In the menu of LGMobile Support Tool choose "Customer Support"
then click on "Recovery Phone"
in the pop-up window enter either IMEI/ESN/MEID or Model+S/N and click "Check"
Then the Mobile Update Tool should pop-up and start downloading+updating
Lots of succes!
Had the same issue a while back, even the emergency/recovery flash from LG tool did not work. Eventually the smartflash method worked for me, going back to v10a and the offical update with official LG tool to v20n worked after that...very strange...

Exactly the same thing happened to me just last night. I was prompted for a V20E (PHL) update. After download and install my phone got disconnected and was stuck on the S/W update screen even after I removed the battery several times.
I found a recovery step by step here and gave it a try. I unplugged the USB, removed the battery, reconnected the USB, pressed vol(-) (not sure about this it was already midnite and I was desperate) and pressed the power button. LG app connected and I chose recover. Entered IMEI and it started downloading again. I tried to get some sleep and a few minutes later I heard the phone startup sound. Hooray! Initially I thought I was back to V10D but the version confirmed I was now on V20E. Double hooray! Still a fail for LG though. Will the same adventure happen when ICS comes out (in two years or so)?
The problem is, that you probably had a cust ROM with ext4 support and that doeant work with stock ROMs, --> bootloop

No custom or root. I was running a plain-Jane V10D before the upgrade.
You should report this bug to LG.
I emailed customer service. They apologized and asked me to bring it to the nearest service center
same thing happened to me.. but what i did was i went to LG mobile in MOA and let them restored my phone but mine is V20b.. is V20e a newer version?
V20B was announced last month. I tried upgrading to that but it went into the phone disconnected error so I decided to wait until I can visit the LG kiosk.
Then V20E came out so I thought let's give it a try hence my adventure. V20E is still 2.3.4 though.
I can't post links yet so try to search for the firmware list. It basically says V10A >> V10D >> V20B >> V20E.
ah i see... thanks man.. i'm still new to these stuff i need to read the threads here to learn how to flash and maybe try V20e
Hi
I'm helping out a friend, which O2X I have rooted and flashed WIUI on to (I previously owned one myself too)
For some reason the phone started to get hot after a while and used up the battery fast, until one day where he couldn't even turn it on again.
Now, he has been trying to fix it himself with NVflash, but no luck, so now its up to me and you guys.
I have used the smartflash tool and flashed the EURO OPEN stock ROM and everything went succesfull, but when the phone reboots, the LG logo appears, and it bootloops.
I tried both with battery and no battery in, but still no cigar.
Any suggestions what I should try next?
PS: If I try to turn on the phone normally, nothing happens. not even a blink from the screen, but I can get into S/W mode and APX
Try lg update tool, choose recover as option, then choose imei as entrance

EDIT: The software says the update is not compatible (dunno if translation is correct, but you get the point)
Update is aborted :/
No more suggestions on what to do?
Tried:
NVflash
Smartflash (Flashed EURO OPEN rom)
LG Update tool (recover function)
The phone still won't boot.
Smartflash is the only solution like you said that the phone can boot in s/w mode try to dig some answer in smartflash thread or search in google i know you can find some answer there

Assuming you have carried out the procedures correctly, looks like this device is actually defective. Probably not what you want to hear, I know, but...
Before giving up completely, you can NVFlash it again (using the original 10C NVFlash from Modaco) and post the log here. Wouldn't get my hopes up though.
I bought a Optimus Black and i wanted to delete old account, so i reseted all phone options in settings. After that phone turned off for 5 seconds and turned on with LG logo and flashing keys. And it's not end. The only thing i can do is turn to SW Uptade Mode, when i pushing Volume up button and connect with USB to my computer. SmartFlashTool didn't work, B2CAppSetup.exe don't want install. Can I do anything else? Is it BootLoader broken?
i dont know what is B2CAppSetup.exe but if you want to run smart flash, you should install usb drivers first.
Look this page for drivers. http://www.lg.com/tr/telefon-destegi/lg-P970-LG-Optimus-Black
sorry, B2CAppSetup.exe is LGMobile Support Tool. I have USB drivers, and Smart Flash worked corretly (i think, there is a text on green background "... completed" at the end), but phone reseted and still have a bootloop.
you flashed cwm integrated bin file?
if so, after opening cwm, did you make wipe data?
if you didnt, it will bootlop
I did everything according to the tutorial http://forum.xda-developers.com/showthread.php?t=1448803 and i can't open the cmw.
try this
it is cwm integrated bin and fls files
flash with smart flash tool
after flash, cwm opens automaticaly
after that choose wipe data
and reboot phone

If it still doesn't work after flashing with Smart Flash Tool then take it into repair shop. It's a hardware problem.
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?

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.

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)

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.
