Hello..
I have a problem trying to instal cyanogenmod on my phone.
First I have all drivers updated, I can actually use my phone as pen drive, I have the lg software working and etc,
But When I try to use SmartFlash Tool, there is no connection the "Com Port" to select. The phone isn't found.
Then I tryed "Unlock Root Tool", and it worked well.
I used "Root Checker", and it says that my phone is rooted.
But now I need to flash a new room, but I can't access the custom recovery menu.
I installed clockworkmod, and tryed to flash the recovery menu, it says downloading until 100%, then change to flashing, and stays there. won't go anywhere.
when I try to flash rom from the rom manager, it stops working.
When I try to reebot into recovery, it reboots the phone, but don't go into any menu, it does a factory reset, and I have my phone clean again.
What can I do?
Thank you.

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.

So I was putting V21A on my p925g, got it on and working fine, rooted it, and then when I started to flash CWM, it started acting funny. It told me to mount the SD card, so I went into options and mounted it, everything seemed fine. I then went to flash CWM again and it told me to mount the SD Card again, so I restarted my phone, and thats when it stopped working.
When I boot into Android System Recovery <3e> it says:
E:Can't mount CACHE:recovery/command
E:Can't mount CACHE:recovery/log
E:Can't open CACHE:recovery/log
and if I try to wipe data/cache/ or any of the options, it says completed, then it says E:can't mount CACHE:recovery/log
So.. am I totally screwed now..? Is there a way I can have my device recognized by USB so I can re-flash V21A, or recover the phone?

Yes it boots to the logo, but the problem is I can't get it to be recognized as a USB device.. Therefore I can't flash, or do anything like that..
Edit: Also I've tried to get download mode to work, but I can never seem to actually get it to work.
Ok turn It off pull the battery out then hold down the buttons for download mode plug the usb in and put the battery back in all wile hold those button down and let go when it vibrats or when devise manger sees it

When I attempt to start my phone in download mode, in device manager COM&LPT section will show up with an Unknown device under it, then quickly disappear - There is a bubble in the bottom right that says there was a problem installing hardware.. Any ideas?

Haha thanks anyways, I managed to get it working. My problem was holding down the power button too long, which would shut the phone off.. >.<... Your thread is very good, and straight forward, ive learned quite a bit about my phone. Just a tip to others who flash the v21a - root using super one click, and then flash CWM via dark's flash manager, I tried to flash through rom manager, and it gave me the option for the optimus x2, thinking nothing of it, i flashed it which was the source of my problems.. im now using the King 3D rom.. has everything I need, the only downfall for me is frequent browser crashes..

Optimus 3D with an identical problem
Hi guys,
UK based noob here in desperate need of some help! My LG Optimus 3D won't boot past the stock Android recovery screen. When i select "Wipe cache" etc it displays "can't mount CACHE:recovery/log".
Using the method of pressing volume up & power button i can get Windows to recognise the phone when looking at Device Manager (it shows "LGE mobile composite USB device"), but ADB doesn't let me communicate with the phone and neither does any other program.
Please please please can someone help me?! How can i fix my phone?
BACKGROUND-
I got to this stage after doing the following: i used LG Mobile Update (after a LOT of messing about trying to get it to work) to update to Android 2.3.5. It kept all my data and settings but unrooted my phone. So i re-used SuperOneClick to root my phone again.
Upgrading to Android 2.3.5 didn't give me the updated stock email app, so i wanted to try and update that myself. I went into ROM Manager.. and here is where i think i made my mistake. Instead of flashing ClockworkMod Recovery as i would do normally to do a backup image of my phone, i instead went straight to "Backup existing ROM" in the main ROM Manager page. My phone rebooted itself.. and now i am where i am. Screwed!

I'm not exactly sure, but once I got my phone in download mode (volume up + power) I just used dark lestat's guide to flash the european V21A KDZ. Once I flashed that, I downloaded his recovery manager, and flashed CWM that way. The first time I flashed CWM via rom manager is what caused all my problems..

Yeah that's where I went wrong too.
I seem to be able to get it in some sort of download mode, but I'm not entirely sure. I use the volume up + power button technique. I used the LG update software to download a recovery image and it started updating the phone, but when it gets to 15% complete it says the connection between the computer and the phone has been lost. It's really annoying!
I'll re-read Dark Lestat's guide and try that. Thanks for your response.
Got it working! Dark Lestat's guide worked a treat. I honestly thought I'd bricked my phone.
First thank you for all the wonderful work there to help us make the best out of this phone.
Yesterday, I tried to install the CM10 ROM (cm-10-20121126-UNOFFICIAL-ancora_tmo) but encountered a serious problem. Since I flashed a custom ROM last time in Aug., I haven't updated the recovery (CWM-base Recovery v5.5.0.4b). When I booted into the recovery, I found it lost all its functionality. To be specific, any selection on menu options (reboot system now, ROMwipe, wipe cache, etc.) yielded no result but a screen with a circling arrow covered by a hat. After that only the power button worked and it would simply bring you back to the main menu. I tried to communicate with the phone in ADB mode and it worked (by that I mean I can reboot it from windows command shell: adb reboot recovery). Now I have no way to update the recovery and install new ROM from there.
Any help would be highly appreciated.
If you can communicate via windows then install Odin and flash from it. Full instructions is on the wiki page

This may seem stupid but how are you selecting something? You should use home capacitive not the power to select. This symptom is the result of tapping the power button, its kinda like sleep

I'd followed the instruction and found the Odin rebooted to the exact recovery! There it showed a few lines like:
Galaxy Exhibit CWM-based Recovery v5.5.0.4b
Finding update package ...
Opening update package ...
Verifying update package ...
E: failed to verify whole-file signature
E: signature verification failed
Installation aborted.
Now the phone can not boot into the original ROM.
When booted into recovery use volume keys to navigate in cwm. Also retry to download the ROM and try cwm before Odin.
Odin is on computer and phone is hooked via USB cable. It cannot boot into cwm if followed Odin. You ha e to download Odin and drivers for cell to be recognized.
Do a YouTube search for Odin and watch the vid it will show you. Be it noted that cell will need to be set into download mode and USB enabled.

Yes, I used the home capacitive to select those options on the main menu. No matter what I choose, however, the power button can get me the circling arrow with a hat. Another push on the button, you are back on the main menu.
You are deffeinitly booted into cwm so I suspect from the install error that the signature verification is what's failing. Try another ROM or redownload and try again

I've redownloaded the uvlg3.odin.zip package and checked its MD5. Everything is OK. Then followed the instruction on the Wiki page, but ended on the same CWM recovery screen with the same error message.
The problem is: it seems like the phone boots successfully into the recovery, but it only shows the main menu with no option functioning (like I described before).
Has anyone read about similar problem anywhere before?

Are you running Odin with your phone in Download mode? Like they said, Odin shouldn't re/boot into recovery automatically.
Also make sure the auto reboot option in odin is cleared.

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.
