[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.

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.

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

you installed cwm without unlocking bootloader. re-flash 20a/20b (jellybean 4.1.2) kdz, then unlock your bootloader, then install any custom recovery you want/need

Have i go bak to JB anytime?

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

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

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

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

Wait...
You just rooted, but didn't unlock the bootloader? If you want to install CWM on this device you HAVE to unlock the bootloader first!
And do you see the 1st bootlogo (not moving one) or the 2nd bootlogo (this logo is moving)?
Try to pull out your battery for at least 10 seconds, then plug it in again and start flashing a new KDZ, I guess there will be no other way, since the recovery will be corrupt...

Do you see two red lines at top . If so your bootloader is locked and don't allow cwm recovery to work Try use power + vol up while phone connected to pc it should get you to so called recovery mode from there try reboot and it should work then you have to unlock bootloader to get cwm recovery to work
Another thing I didn't try myself but installing cwm recovery is replacing file dev/block/mmcblk0p1
Maybe if you have the original file copy it over there return you back to stock recovery

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.

i dont know flash kdz ( ithink my device got bricked)

Once you have the cwm power+volume down press together and wait till cwm shows up. Then you can use as you probably planned to do with onlocking and flashing cwm.
On your pc you can download rom and transfer via usb /mount usb or smth like that
Then follow instructions of rom devs to install.

If that doesn't seem to work, you should force an update through the LGMobile Support Tool. Then start over again. You probably didn't unlock your bootloader properly (you can check it in the hidden menu or in S/W Upgrade mode), or you flashed a wrong recovery.. Good luck
