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...
@ 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.

power button but it goes back to "Bootloader. Reboot . Reboot Bootloader . Power Down" menu after
showing the Nexus X logo for a split second)
Have i bricked my phone ? I am starting to panick here... Help pls !!!
[Additional Info]
Before this problem i was running CM Rc2 with no problems. Rooted with 1-click root program found
here in the forum. Used Rom Manager to flash CM Rc2. I also applied the 720video mod as well and
metamorph my statusbar. The backup files made by Rom Manager prior to flashing CM Rc2 are kept in
my computer and is not in my sd card.
Hboot -0.33.0012
Radio -4.06.00.12_7
try reflashing the amon_ra recovery in fastboot.
how do i do that ? when i press the Power + Trackball button .. it shows a Red rectangle wid wid FASTBOOT written in it.. i select Bootloader, it shows HBOOT wid a blue rectangle. After that i select Fastboot and it shows back the Red rectangle wid FASTBOOT written in it.. do i have to use the adb command method using Android SDK ?
I havent use it before so i am practically new to it.. I think i need to install Java for it to run as well ...
oops double post
Intall droidexplorer and see it it will connect to the phone while powered on in any state. If it connects delete a file or 2 from cache and try to reboot it from droudexplorer.
Sent from my HTC Magic using XDA App
will that program work with my N1 ? and my phone is stuck at the first logo.. it wont boot.. I just have to power up my device and it will detect it ?
i just rechecked DroidExplorer's requirement:
====================================================================
Requirements
* Windows XP or later ( looking for someone to branch UI for mono development )
* .NET Framework 3.5 SP1
* Rooted Android Device w/ Busybox
* Windows USB Drivers (usb-drivers-r2) - will be included in future
o The Droid/Milestone & other Motorola devices require Motorola's USB Drivers, have not yet confirmed
* Enable USB Debugging on device under Settings -> Applications -> Development
====================================================================
I have to have USB debugging enabled.. How do i do that when i cant even start up my phone in the first place ?
Lots of problems lately reported by those who used 1-click root and ROM Manager, and didn't actually know what they're doing, and once something went wrong - they don't know how to get the phone back on track. I'd suggest putting a disclaimer as a sticky in the forum - "1-click root apps and ROM manager are bad for health, if you don't know what you're doing. Go through the guides first, and learn how to flash ROMs on your own!"
So, my suggestion is: go to Nexus Wiki, open "Guides" section, open the section that deals with returning back to stock using PASSIMG.ZIP method, and follow the steps. From there, if it helps you and the phone is restored back to stock, you can do whatever you want. I suggest doing it using the guides in the Wiki (except for rooting itself, perhaps).
the 1-click root worked.. there was not much of a problem rooting it except for the AmonRa or Clockwork not registering at the first time.. my problem came after i try to use the Type Fresh apk.. Here's what i exactly did.. i accidentally click restore default fonts on Type Fresh and it prompt for reboot of my fone..(I havent changed my fonts yet).. Instead i clicked no and i uninstalled the program(stupid thing to do).. Reinstalled it and then changed all the fonts listed in the program to Comforta.tff... Applied it then tried to reboot.. And thats where i am at; STUCK...
I read the amonRa installation guide via Fastboot and it shows that i need to unlock the bootloader.. Well the 1-Click root does not unlock the bootloader but still i could use AmonRa or Clockwork recovery and even install custom roms..
[1.]Do i still need to unlock bootloader to install recovery ? or i was thinking of sending it back to Google for replacement saying my fone won't boot, since it still has a locked bootloader... (will take few months since i am somewhere near China/India)
[2.] Will they even replace/fix my phone since it has custom rom with locked bootloader?
[3.]Can i check if my fastboot is working before i unlock bootloader ?(if that is the only option i have)
[4.]Can a bricked phone do the power button + trackball menu at all ?
i will look into the passimg.zip option as well.. Since my phone is rooted with locked bootloader, will it un-root it ?
[5.]And where is this guide in the wiki ?
http://en.wikipedia.org/wiki/Nexus_One ? (can't find there)
http://wiki.cyanogenmod.com/index.php?title=Nexus_One ? (can't find there)
And since anyone can flash custom roms without unlocking bootloader using 1-Click root, Cyanogen's wiki should update this portion, here (http://wiki.cyanogenmod.com/index.php?title=Full_Update_Guide_-_Nexus_One)
"In order to flash a fully stock Nexus One with any ROM, you must first unlock the bootloader of your Nexus One and install a custom recovery image. If your Nexus One's bootloader is already unlocked, skip this section. "
ok so now i have unlocked my bootloader.. installed AmonRa and successfully installed Cm rc2 again.. tks for the guy who insisted i install my recovery AmonRa via fastboot.. to others.. No thank you.. Damm i hate the Unlocked logo.. Goodbye warranty... !!!
Gosh... I should have spelled even more?
The Nexus One Wiki is a sticky thread on the top of the page:
http://forum.xda-developers.com/wiki/index.php?title=Nexus_One
If you click Guides and Tutorials, you'll see - 3. Unroot / Restore your Nexus.
There are 2 methods, I've meant the PASSIMG.ZIP one. It would restore the phone to the stock image of your choice, without unlocking your bootloader and without resorting to fastboot, but completely reflashing all the images on the phone.
If not sure, what to do - you should have waited.
Not that there's any harm in having fastboot actually working, though. And the warranty will still be honored, as long as the phone has a physical problem. Plenty of threads about it.

Hello everyone!
I'm a new member from today but I have read (and read and read...) the threads here and on every forum I could find, in desperate search for an answer to my questions, but so far I have found none.
Don't shop my head of now but could someone please be so kind and help me root my LG Optimus 2x by giving me a step-by-step info AND include the correct files AND then tell me what to do to have them installed?
There seem to be all too many different alternatives and I am really confused!
Here's what I've done so far -
I had Gingerbread installed and got the phone rooted with SuperOnecClick.
Upgraded then the phone to Ice Cream Sandwish 4.0.4 with LG Support Tool and lost root.
Tried to root with SuperOneClick again but constantly got stuck at # 5 or # 7 (waiting for device).
So, how do I root and where do I find the correct firmware for this?
Android
4.0.4
Bandwithversion
1035.21_20121130
Kernel-version
2.6.39.4
Version
IMM76L.LG-P990-P99030a.1211302332
Software

Superuser (not rooted)
SuperOneClick
Hi there,
Since you upgraded to official ICS, you can't use SuperOneClick to get root access again, but fear not as there are alternatives. Here you will find three different methods to root your device. In your case, I believe you need to use either the second or third option listed there.
Be aware that the third option will wipe your device, including your internal SD card, so it'd be a good idea to backup first, just in case. All three methods are harmless, but you never know.
Thank you for your reply! Now I'm on and a step closer in fixing this.
So, my phone cannot be rooted because of Official ICS?! Oh!
- that was new news to me and it could have saved me countless of hours if I had found that information out sooner. A pity I did not write here weeks ago!
I have some more questions though and I think I'm going for the 2nd option in the link you gave me.
"Put your phone into nvflash mode". Do I need a tool for that? (Here I was linking to a nvflash-setup, but as I am a new memeber I am not allowed to post outside links yet). Or do I just hold down volyme + power in order to get into that nvflash mode?
By "unzipping attached archive" I assume it means zipping it on the PC and not on the SD card?
When doing this procedure, do I have the phone in Charging or Mass storage mode?
Just a few questions I hope you (someone) have to time to give me an answer to - Thank you!

You can get it rooted, only not with SuperOneClick ^^

To enter nvflash mode turn off your device, remove the battery, then press and hold Vol- and Power at the same time and plug your phone to your PC via USB. Then follow the rest of the instructions.

Yep ^^ you need to extract the files from the zip to your PC.
Ok, next question :
"boot into cwm and flash SuperSU Root.zip"
How am I suppose to flash anything when the telephone is black and I'm not into it and only work from the computer?
How do I do that?
I'm stuck with a black screen only on the phone.
I heared nothing or saw nothing that sais (sound) that the phone is connected through the USB, but I have followed each step and are now stuck at above question.
Greatful for more help!
MissLight said:
Hm. I have now read more closely on the linked site. Why am I to download ICS again, I already have the same ROM?
Or do you mean I have to change the official ROM to this one in order to root properly?
Click to expand...

No, there's no need to reflash ICS. The second method listed there just flashes the unlocked bootloader + root + custom CWM, and it won't touch your data & settings.
MissLight said:
I tried Volume down + Power without battery. Nothing happened, the phone was stonedead even when plugged in with USB.

That's OK. When in nvflash mode, you won't see anything on screen. All you'll get is the sound it makes when connected to USB.
Don't worry, you're nearly there! Keep going!
Edit: just realized I made one small mistake. To enter nvflash mode, you need to press and hold both Vol+ & Vol- at the same time (this also requires removing the battery first). Sorry about that!

Oh! That explains why. My next question was published above your question and still remains.
How do I "boot into cwm and flash SuperSU Root.zip"?
Edit : This procedure does somehow not work on XP so I changed to Windows7 and have now come a bit further. The only thing remaining now is that the computer sais that it cannot find the USB device.
I have downloaded the LG modem and USB firmware but maybe I need something else? Does the firmware in a folder on C: just as NvFlash and SU-folder.
Got OK with USB firmware and all set to go now.
But, in NVFlash Recovery it sais :
Please pick bootloader, or exit (1,X)? (I pressed 1)
Attempting to flash bootloader...
Nvflash started
USB device not found
Program will now exit
So, I'm stuck.
The phone can be found both in Mass Storage mode and I got a OK that the drivers are installed.

Alright, it sounds like you still need the APX drivers. I believe you can find it somewhere on the Development forum (find tonyp's threads, I'm sure he has posted it there). If you already did this, then remember to hold and press both Vol buttons when selecting option 1 so Nvflash can connect to your device and do all the magic.
Don't give up yet, you're a few seconds away from rooting your device (and learning stuff at the same time ^^).
Tried exactly as you said but still no luck. But I'm not giving up!
I found a APX driver. Installed and unziped in the same file as NvFlash. Rebooted PC and tried again.
Still no luck - "USB device not found".
What am I doing wrong?
BEFORE removing the battery from mobile, shall I have Mass Storage or Charging marked?
Do I need to have USB Debugging marked or not?
Latest Update :
I managed to install Nvidia usb boot recovery in the device manager and it's OK.
The device is now found and I got the phone into S/W Upgrade please wait while upgrading-mode.
And there I am - stuck. Nothing more happens. It has freeze.
What do I do next?
A question : How do I "boot into cwm and flash SuperSU Root.zip" - how do I do that?
Nice! Has nvflash finished flashing? If so, it should be safe to unplug the device now.
Put the battery back on, press and hold both Power and Vol- at the same time until the second LG logo appears to enter CWM. From there, select "Install zip from SD card" (or something similar) and select the SU zip file you previously stored onto your sdcard. CWM will then flash the necessary files to root your device! Once done, reboot and enjoy!
Hi again! It's not going as well unfortunately. Very mysterious. *laugh*
"until the second LG logo appears to enter CWM. From there, select "Install zip from SD card"
When pressing Volyme - + Volyme up + Power I get a black screen. Nothing more happens.
And after flashing the flash-boot in NvFlash the phone goes into s/w upgrade please wait while upgrading-mode.
And there it is. Stuck. Nothing more happens. I repeted the procedure for 5 times. I only get to the s/w-mode.
After 3 hours I unplugged it and will restart my search today for what's blocking it to continue.
Hm? Hmmmm....? Any suggestions in what might be wrong?
You have to push and hold only Vol- and Power this time ^^ That will get you into CWM if the flash-boot.bat went right.
Great, I'm in!
But I managed to place the SU zip on wrong device (internal, not external).
How do I get out from cwm-mode, there's no "exit" options?
There should be a Reboot option, use it and your phone will boot as usual. When you're done moving the SU zip file to the external SD card, power off your 2X and do as instructed above to enter CWM again ^^
Thank you for replying so quickly!!!!!
There is a reboot option BUT I unfortunately pressed adb sideload (hoping to install the SU.zip that way, but the device is not to be found on the PC at all in that mode so I can't reach it through cmd either!).
So, I'm completely STUCK at adb sideolad-mode.... (sorry). I'm starting to get grey hair.
Hahahah XD don't worry, just remove the battery and put it back again ^^
*BIG SMILE* Guess what? I have root access! *jumping up and down of joy*
THANK YOU! THANK YOU! THANK YOU so very much for your guidance!
I believe in passing knowledge forward and I will do my best to help others noobs with what you just learned me!
For a stubborn noob like me I was not reflecting over some obvious things though. As that the SU.zip had to be placed on SD-card (and not being unzipped in C: )
And that I had to get the Nvidia APX in order to make NvFlash to work properly (and search through Google to find it and how to make it work).
And that when I'm stuck in CWM I can always remove the battery.
Once again. I'm very glad and THANK you and all credit to You!
You know, I decided to help you because of your will to learn and do stuff by yourself. Many come here and ask for help without trying anything by themselves first, so I actually enjoyed watching you learn ^^
See? It wasn't that hard. All it takes is a lot of reading and patience.
Good job, and welcome to XDA!
Anyone else having this issue? Procedure I followed was at "[ROM][ICS][P920] First ICS 4.0.4 Full 3D ROM Ported From SU760". Honestly, I'd really like to post this in the appropriate thread, but can't yet. I am experiencing the phone powering to the LG screen and off repeatedly upon plugging in a charger as well as hitting the power button. I had hoped it might just need juice but no dice. Does this really have anything to do with CWM? There is something about a modified USB cable in the original post that refers to a "screen issue" but there is no clarification to what issue. Here is my original post with a follow up:
Thanks!
OK maybe I should clarify

I do get the "S/W" screen with Korean text when I boot into download mode (if my terminology is correct i.e. up vol + power + connect usb cable to pc, then insert battery. How can I recover? Start over? How if I can't set connection settings on the device? ACK I have been at this far too long and must rest, hopefully with shiny new replies in the morning.
So to clarify, I had the ROM running fine. I was about to flash a zip, but was tired and had not loaded it onto the external SD. I am using the CWM referred to in the original post here:
"[ROM][ICS][P920] First ICS 4.0.4 Full 3D ROM Ported From SU760".
The app went through the motion but did not install anything, I assume. Then I hit "Boot to recovery." Could that have caused this? Now I get the LG screen and then no power, up to 3 times if I hold power. I am hesitant to follow any bootlooping procedure since I don't know if they apply to this phone and if that is the problem (it appears to be, but I am new to this. I WAS feeling nice that I was able to get ICS up and running). I cannot seemingly boot to recovery to reflash or downgrade. Also, when I connect to pc in download mode I get the Korean "S/W" screen with circular arrows and Korean text, but LG Flashtool does not connect. I recall hitting "Recover" in English during the original ROM flash. Please help!
I think it could be a bad ROM.
I assume that you can't boot to CWM/recovery mode and reflash a different ROM.
If I'm correct, I'd try to reinstall CWM via USB if possible...
Thanks for responding!
Someone IS out there...
I can't seem to boot the phone itself into CWM recovery no matter what. The phone was not left in debug mode, unfortunately. I am looking into using ADB to perform some kind of boot loop recover, but at this point am not confident in doing so. Any ideas here would be nice.
I see a boot loop recover guide on the forums, but it seems to assume I am able to boot the phone into CWM recover.
FYI I am not fluent in 'Android speak' but am getting there.
So if I am able to get a COM connection to the phone in download mode (which seems to be the case, as I mention with the S/W screen with circular arrows and Korean text- I do see a connection in Device Manager) is it possible then, to reinstall CWM as you mention? How? Would that, then, hopefully, revert it to a state where it is not, seemingly, attempting to implement some non-present process on booting?
OK Finally!
OK so NO one seemed to be able to help with my direct issue but I was able to at least reflash to the 'stock' Korean ICS port and get the phone up again. Ho Hum. Maybe I'll start an Android reflashing business. I will be trying AcidHazard mod to flash out all the bloatware. And DEFINITELY will be more careful with ClockworkMod.
This is what I did:
http://forum.xda-developers.com/showthread.php?t=1448803
Alright forget what I said about further flash for now
I was gonna try to flash in the Acid Hazard music rom which looks awesome, but the Prada CWM I installed (mentioned in the original xbsall ICS ROM installation procedure) once again caused a boot loop and I had to reflash the xbsall rom again. Until I see a CWM that I know will not cause this, I won't be booting into recovery. As I'd like to make a Nandroid backup, what is up with this CWM being a problem with my phone (ATT LG Thrill P925)? Anyone?

Hi!
I just rooted my brand new LG optimus 4x HD, and when I was going to install cyanogenmod on it, the phone stopped working. I pressed to restart in recovery and installing the rom, but when it was about to restart, it only says something like: unrecoverable boot loader, and something with kernel. I don't know what this means, but I hope there is a way to fix this, because the phone is brand new, and now I can't even start it.
Some suggestions?

Just flash original stock KDZ file with kdz flasher.
If you want to install CM, you do not need a rooted phone, but an unlocked bootloader.
Check the respective threads for details on how to unlock the phone and then flash CM.

ok, i'll try that in a couple of hours when I get home, Thanks everyone! I'll be back if there is another problem
in the lg pc suite that comes with the phone there is an option in "Device" for "emergency firmware recovery" this should be a relatively easy way to restore your phone if it allows you to do it without booting up otherwise use the method posted earlier. to get into the correct mode on the phone turn phone off, then whilst holding vol- plug in the usb (don't press power button) this should enter software upgrade mode.
after this you will lose root and if you unlocked your bootloader will relock it.

to get into S/W upgrade mode, remove battery, insert battery, hold the vol-, and plug in a usb attached to a computer (keep holding vol-).
hope this helps. also try a different pc usb port or a different cable (just to eliminate any variables)

Hi astr_x,
Do you have any example links for the respective threads you mention? I have tried adb and fastboot. I hold Volume down + plug into my computer and I get the Unrecoverable bootloader error that was mentioned above. In fact, I get this error even when I plug my phone to a normal plug (and not PC). Anyway, I connect my phone to my laptop (I always get the error mentioned) and when I type the relative adb+fastboot command in cmd (after installing all the relative drivers), I get "Error: Unknown device".
Any thoughts?

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.
