CWM has a recovery mode. I had a nasty error like that, and on the 970 I just rapidly pressed the volume down key (or something like that) and the phone returned to CWM.

the stock ics you flashed maybe locked that's why your getting security error from LG, I've tried this when I flashed using smartflash with the kdz files. Just make sure you dont inject CWM into the file when extracting it to .bin & .fls file so that you won't get the error

[Q] how to remove clockword mod recovery

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

Here's howto remove the ClockWork Recovery Mode:

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.

[Q] Help. Thrill wont boot (at&t logo), messed up pretty good

1. Rooted
2. Don't think I had USB Debugging on prior to this situation
3. Didn't flash a rom (dont even know how)
4. don't have clockworkmod
I installed the root required app LCD density changer by beansoft... tried permanently changing my lcd density (resolution) to 200, looked back at phone several minutes later and it was stuck on the at&t logo. I didn't do a backup like they said, in case anything goes wrong (didn't expect anything to go wrong.........). Now, everytime I try to boot my phone, i get stuck at the At&t logo screen (NOT infinite loop... just frozen logo). I have tried factory reset multiple times... but ofcourse that didn't work because that doesn't affect system preferences ( like the density/resolution).
Beansoft suggests this to fix the issue... but i can't get it to work
densitychanger.blogspot.(com) (towards the bottom, where the highlighted green text is)...
How can i get that file onto my phone's memory? My phone wont even turn on. I tried putting it on the microsd card, but the file doesnt show up in recovery.
Someone please help me... I just want my phone working again... By whatever means... Flashing a new rom, the update.zip method by beansoft... idk ... just want it working...
HELP :'(
P.S. I dunno how to work adb... every time i try and use it, i get the "device not found" thing... ( i have the drivers installed)... So if that's how I have to fix my phone... PLEASE be very descriptive in instructions....

the 200 dpi setting does not work on the Thrill, which is why you are stuck in "bootloop"

Well looks like you're kinda screwed since you don't have clockwork installed, I'm not sure if you can install a new ROM... but have you tried EVERYTHING in android recovery?
If you don't know how to get to recovery... it's Hold down volume key + 3d + power, until it vibrates then use arrow keys to move around and 3d to select if you dont have clockwork...

Do you havet the emergency mode like most LG smartphones?Here is how you check pull out the battery and the plug it in(so your phone turns off) and then hold down the volume up +voulume down and power button if it worked you should see a yellow screen and a "Emergency mode!!" title.Then google for a kdz update tool and a kdz firmware for YOUR phone.You will also need the LG mobile united drivers.If you are on windows go to control panel and disable the lg modem.Then connect your phone(in emergency mode) to the computer open the update tool then click on select KDZ and navigate to your KDZ then in phone mode select emergency_something iys the only one.Than click flash KDZ and after about 5min your phone should reboot and it wilk work.Its importiant to note that you will lose everything on your phones memory its like you flash a rom you start out fresh you also loose root.Good luck!

Im having the same problem as the person before me, but my phone is stuck on the lg logo screen. My phone is rooted and I do believe I have installed clockworkmod when root manager asked me to. My phone froze on me while going through the root manager app, when I tried formatting it through the reboot screen I ended up with E: can't mount CACHE:recovery/ command, E: can't mount CACHE:recovery/log, and E: can't open CACHE:recovery/log.
I've tried following instuctions from this site: http://www.lg-phones.org/how-to-flash-lg-thrill-4g-to-android-2-3-gingerbread.html
Until the last one cause i don't have an option to instal stuff from my sd card

You don't have clockwork then.That is your stock recovery.I had this problem too.I flashed the wrong recovery and i got stuck on the LG logo.I fixed it using fastboot flasher idk is it the same combination but on my phone it is volume up+call+power button.Uf it is correct you should see a sign saying fastboot mode udc_start or something like that then use the fastboot flasher to flash a recovery image for your phone.After the flash is complete reboot your phone but first do a NORMAL boot so you can see if the problem is solved.If it worked then you can safely boot into recovery.

Thank you for your support guys, but as it was to difficult, I just got a new one from at&t
I am in similar situation but I am rooted AND I have CWM on my phone. I can boot into recovery just fine and install from sd card and all that jazz but when I try to boot normally I don't get past the LG logo. It just hangs there forever. Do I just have to get a flashable ROM onto the SD card and boot into recovery and flash??
I have already tried wiping data, cache and dalvik to no avail.
Any suggestions??

I rooted phone, everything fine. I flashed CWM, everything fine. When I rebooted system from CWM then phone booted but hung at the LG logo. Now only thing I can do is boot into recovery or boot to the LG logo for hours... Don't even know how this could have happened as I haven't flashed anything, just root and CWM...

[Q] LG - P970 bootlooping

Hey guys, i really need some help asap. I really know i will be called a noob for asking this, but i had flashed V20n into my Lg Optimus Black (P970). After i installed Zeus mod on it i got a few bugs, very rarely and some times it wouldnt start. I used to take the battery out for a few hours and everything worked perfect. The last 2 days to it refuses to open. Stays on the LG screen and the buttons flash (has reached CMR screen, i have done a format and then restarted it, and nothing works now AGAIN). I have used easy flasher, trying to install the v20s from 3 different forums but none of them helps. I would really appreciate if i could get some useful fast answers or other link refferals. I have absolutely no personal time within the day, and i will need to know fast in case i need to take it to the service center.

If not, download it (use search to find it), then go to my noob how to, download the patched v20s provided in there and then it should work fine again. Dont forget to flash the superuser.zip and do a data, cache, dalvik wipe.

great, lg emergency recovery tool tells me this model is not supported for upgrading =.=
Similar problem, I was on Huexs´s 6.4, was rooted, recovery was working, then I flashed v30d by tantrums, was using it without problems, then some problems with sd card, from that point I am not able to run recovery, so I tried to flash patched v20 with Smartflash, but when it goes to rebooting, it always stay in bootloop. Only way for me is flash v30b, then root it with Unlockroot, but thats all, I can normaly use phone rooted, but I am not able to push to phone recovery image, so I can not flash any zip file ( like new kernels. etc.).
Managed to flash V30b
i managd to flash the v30b by the kdz updater but... Everything was working normally. I shut off the phone so i can go to sleep and i put it to charge. the picture i got is the lg logo with a white faint line down the bottom of the screen again. I unplug the charger and remove the battery. The next morning it worked perfectly again for aprox. 9 hours, that i was at school. Then i try texting my gf and the pictures below show what happened... WTH? Any help would be deeply appreciated :-/

@robusto try flashing v30B. then root your OB and flash TWRP recovery. You can do it like this:
1. Install goomanager
2. Open goomanager and provide root permision
3. Hit menu and choose 'Install OpenRecovery'.
Now you have TWRP Recovery and you should be able to flash any .zip file.
It worked for me.

@robusto try flashing v30B. then root your OB and flash TWRP recovery. You can do it like this:
1. Install goomanager
2. Open goomanager and provide root permision
3. Hit menu and choose 'Install OpenRecovery'.
Now you have TWRP Recovery and you should be able to flash any .zip file.
It worked for me.

I am now on stock V30B Europe, rooted by unlockroot, uninstalled garbage and apps, whitch I dont need, using Holo launcher and LMT and am satisfied, bechmark with antutu 3100. Only I am not able change kernel, what could be phone speed up, but nevermid. I can live with it. Only can be good to convert some kernel.zip to same file, whitch can be flashed with kdz flasher or smartflashtool. Anyway thanks for ideas.

HeinekenAmstel, try to left out of phone the battery for one day, then try to flash kdz v30b for your country from here http://lg-phone-firmware.com/index.php?id_mod=1, but connect phone to PC without battery in. And may be is good to do it on PC with WIN XP. For me this is working better then on PC with WIN7. Good luck.

[SOLVED][ERROR] Device stuck on boot! Error: Boot Image Signature

Guys,
I'm relatively new to flashing recovery and ROMs..
So, sorry if this is a noob question..
I really need urgent help!
I am on V20a (ESA-XXX) and have successfully rooted my phone.
I tried installing CWM using this method..
http://forum.xda-developers.com/showthread.php?t=2180138
I used the unsecure boot provided by gordon0001
http://forum.xda-developers.com/showthread.php?p=39918805&highlight=unsecure#post39918805
After i restarted my phone, it got stuck at boot!!
Its gives the following error and turns of in 5 seconds..
[LG-Security] Error: Boot Image Signature!
The phone doesn't start and does not go into recovery either..
The phone is not even recognised by my PC.. keeps restarting (to error screen) if i connect to pc..
Please, someone help me.. I'm really scared.. I don't want to lose my phone.. :crying:
I read a similar prob, but no solution found..
http://forum.xda-developers.com/showthread.php?t=2223697
PLEASE HELP!!
SOLUTION:
Reflash .kdz via Software Upgrade Mode (hold Power button and Volume - )
Dude, reflashing your phone should work. As long as SW mode is still accessible, your phone isn't dead yet. Follow the instructions on this post http://forum.xda-developers.com/showthread.php?p=35971349 Be freaking sure all necessary drivers are properly installed.
Or you can put your phone in recovery mode (power + vol +) and reinstall the stock rom using recovery LG tools providing your Internet connection is fast and stable

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

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

I solved the problem flashing back to stock rom.
From this page http://lg-phone-firmware.com/ you may download your original stock rom.
WARNING: IF YOU FLASHED YOUR PHONE WITH A CUSTOM ROM, NEVER TRY TO FLASH BACK TO AN ORIGINAL STOCK ROM.

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

Had the exact same problem as TechnoBraker however if you held the power button as the phone turned to "power save" and you timed it perfectly it would start normally and as long as i didnt try to go into recovery mode it was fine

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

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

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

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

Could be due to wrong drivers. Reinstall them and try again.
