Hello all..
I'm sorry if this is the wrong section, but I can't connect my problem to anything similar..
I've been removing system apps on my phone and, unfortunately I selected Lg Home in a group, and without noticing I deleted it.
I did restart it after it.. and the problems started.
I was able to select the custom Home by LG somehow, but I'm enable to go into settings (getting "Unfortunately, Settings has stopped.")
After that, I noticed that I cannot do really anything on the phone.. my PC no longer recognize my device, usb debugging is disabled.
In addition, I cannot get into fastboot (boot loop, when I'm holding the keys),
I cannot go into recovery too.
I could only get to the LG hard reset page, did reset the phone.. with no success at getting anything back.
I have terminal emulator and SuperSU on my phone (it's rooted).
Is there anything I can do with the terminal? Like send LG drivers to my PC, or restarting in fastboot/recovery?
I even tried to flash the original ROM with LG Flesh Tool.
With that program I cannot get phone information, and when I try to flash I get a message saying that Upgrade stopped due to an error.
It asked me to restart and bla bla.. still same
I did try it from download mode, but my phone did not got recognized on the PC again, so nothing there too.
Whenever I connect the device to the PC, windows is searching for drivers for MTP Usb Driver (and fails everytime). Note: I did have those installed before I messed up the phone.
I have ADB and I'm working with cordova, so I tried to install another andorid on my pc, and it got recognized right away (every driver was installed without doing anything, and I can shell it).
Any advice?
Thanks.
Sorry for spamming..
But, nothing really??

So I tried to root my phone, it worked, and I wanted to oc it. I used ROM Manager, and bricked my phone, since I installed a program (dont remember what its called) that turned my phone into EXT4, when it needs to run on EXT3 or something. So now its stuck at the LG/ LG with loading bar screen and cannot turn on. I'm trying the flash it with nvflash, but it wont work. I got my phone into APX Device mode once, but I failed and had to try again. But now, my computer won;t recognize my phone and I think I'm doing something wrong, because it wont show my phone as a APX Device. I'm obviously new to this so help would be appreciated.

Some people have reported that they have to try repeatedly before it will start in APX-mode. So try again and again before giving up, make sure battery is out and that you firmly press both volume-buttons while plugging it in.
If it absolutely, positively cannot enter APX-mode, then your last hope is Smartflash-mode. Does it start in Smartflash mode if you hold volume-down while plugging it in?
Oh, and make sure you're connected directly to a port on the motherboard.
EDIT: You can try deleting the APX-device from the PC too, to get it rediscovered and reinstalled. Unzip the attached archive and run the batch file in it. (It sets a parameter which allows the device-manager to display hidden and "ghost"-devices before starting it.) Select "Show Hidden Devices" from the View Menu, find the APX-device(s) ("NVIDIA USB Boot-recovery driver for Mobile devices") and delete it/them. Then try to reconnect in APX-mode again. (Have the driver ready.)
Just got my phone into download mode after using the jig, and i have been able to connect to my pc before i seriously F'd my phone by messing with a setting in cwm. I have downloaded and redownloaded drivers from samsungs website, along with installing Kies and that does not recognize my phone. (also i would like to add i am unable to access the phone since it wont turn on without the jig, without jig it just goes into a boot loop.)
THis is what happens when i plug my phone into the computer:
plug in usb (to computer and phone)
let it do its thing to recognize device...
pop-up stating "unknown device" so i click it.
then right-click the unknown device which opens up another window
from this menu it shows Install driver, Update driver and 3 other options.
when i press install driver and update driver, it tells me that the driver is already installed in "device unknown."
At this point i throw computer at wall after 2 days of trying to figure this out.
so messed around and the problem only happens when it is in download mode. but when it is not in download mode it shows up but no use to me because i am trying to flash it to stock. soo i dont know why the error 43 only shows up when in download mode. any help would be great.

Just follow this to update the drivers http://forum.xda-developers.com/showpost.php?p=27205737&postcount=4571 , same thing as what you have done earlier but this time , when it searches for new drivers, you can do the selection for it.
But first reboot your PC after pulling out power cord ...and try the quick solutions first
Ok sen, so i tried to install the driver manually but i am stuck at the part where i have to install something on my phone to allow it to sync with the computer, since my phone will not even boot up. I am starting to think my dear Capi is going to be a paper weight =(
Rooted LG D405n, nothing done to the software beyond that (unless you count having zooper/nova launcher configured on it). Gave the phone to a friend for a short while and she decided to update the software using the LG software update on the phone. After she selected install on the latest update which came out not long ago and was supposedly going to update the apps, it restarted and got stuck on boot screen with Boot Ceritification Error [560].
I've tried this guide http://forum.xda-developers.com/lg-l90/general/guide-flash-stock-kdz-offline-lg-l90-t2803479 but I got stuck on step 4. because I cannot make the PC recognize the device (it does not show up at all), so the LG tool can't install USB drivers. If i try to do it manually (it gives me an option to select a device from a list) it doesn't seem to do anything, just gets stuck on the Downloading USB driver window.
I can put the phone in Firmware Upgrade Mode just fine, but it doesn't seem to do anything useful. The PC still won't recognize the device, however I can hear the 'usb pluged in' sound (I'm on Win7).
Did a factory reset, didn't help.

You could try the LG Support Tool. Not sure it will work but it's worth a shot. The problem with the phone not getting detected by the PC is the fact that 1) The OS was upgraded by your friend and 2) The factory reset you performed . Both of those acts would have disabled USB debugging hence no device detected.
I unfortunately have no encouraging information to give you.

It appears that I have fixed it.
Since The tool would not download the USB drivers by itself I went to the LG website and got them manually, installed them and restarted the PC.
After that I launched the LG Mobile Support Tool, but it still didn't see the device.
However, I clicked Options and Upgrade Recovery. It asked me for my IMEI. I put the phone into Firmware Upgrade mode and the program started upgrading the phone.
After it was all done, the phone restarted, and the software update simply said that instalation failed, I have lost root but everything else seems fine. Rooted again with towelroot and I'm back in game.

Well I'm glad you managed to fix it.
Since this issue appears to be solved, please insert '[SOLVED]', without the quotes, at the beginning of your thread title.
Hello,
after root and bootloader unlock I was trying to instal recovery. Application says that recovery was installed succesfully, but after reboot it stops at logo LG. Now I have only 3 ways - recovery, upgrade and charging mode. Wipe data/factory reset didn`t help. I tried to install soft from beginning by LG Mobile Support Tool, but it didn`t recognise my phone, even after install drivers. Two months before it works good (LG software), but now it has problems. I used LG Flashtool (http://forum.xda-developers.com/showthread.php?t=2179126), but it still doesn`t detect my phone (device is in upgrade mode ofc). At the beginning I could change setting "LGE CDMA USB SERIAL PORT" and disable "PC MODEM", but now I can`t see that in devices manager. In addition when I plug in my LG, Windows sounds like its connected. Now I`m working on 8.1, but when I tried this same operations at 7 it also didn`t work. I was searching a sollution, but I didn`t found it. Do You have any ideas? Please help me, I need my phone alive. Thanks for replies.
I`m sorry, if I wrote this in wrong place.
I have half-bricked P880. Bought just a week ago.
My ROM is stock V10C. I’m trying to get rid of that crap ROM, but so far without success.
I have rooted the phone but flashify is the only app saing that the phone is not rooted. Every other app which requires root is normally working. I can’t unlock the bootloader because phone can’t be recognized by any computer, using different Windows, USB cables etc. It just shows charging but PC doesn’t see any connected device. Nor the phone shows any connection option when I connect it to PC by USB.
I’ve tried to install TWRP (without success) and CWM (successfully) but the phone can’t be load into bootloader. Just an LG logo will appear and this error message:
[LGE_SECURITY ERROR] boot image signature
Critical failure: Unable to start kernel
Unrecoverable bootloader error (0x00000002)
I think it’s still locked.
This method hasn’t help either…
http://forum.xda-developers.com/showthread.php?t=2251407
What’s more, the error message appears almost every time I try to turn on the phone. Sometimes it takes 10 attempts until the phone will finally boot into Android.
Yes I’ve tried basic things like playing with USB debug mode, LG PC suite option/USB tethering… please don’t respond to my question by that kind of suggestions, I’m no rookie in flashing roms and Android problems.
Only hope for me is to flash kdz file via PC (when the phone is off and battery out). BUT I’m unable to do that, due to problem that the phone is again NOT RECOGNIZED by PC. Of course I've tried every kind of LG driver but the problem is in the phone, because the PC won’t even notify by sound that a phone has been connected to it. So I need to change the corrupted bootloader… somehow.
I’ve already searched everything to this issue on XDA and elsewhere - without any solution. So I’m 95% the phone is half-bricked without any chance to flash new ROM.
If none of those things that you said doesnt work, as last resort you should try this

Thank you for a quick reply! However the autor of the method says:
i mean when you get stucked with S/W screen, and you can't flash the device in any way

In my case I can't say that I'm stuck with S/W screen. Because I don't even get in there. Any PC in my home (XP/Windows 7) don't even recognize that a mobile has been connected to it. So there is no S/W screen. The only way I can get in S/W screen is to keep the battery in, but it doesn't solve anything. Because the phone remains unrecognized to PC. Therefore I'm unable to flash anything. A simple explanation in here arose: the USB port in my phone is faulty. BUT, how that can be, when the USB charging works fine and even S/W screen appears while the battery is in?
Either way I'll keep your suggestion as the final solution(since I'm very skeptical of it and also dont have screwdriver small enought to take out those tine srews) if there will be no other responce to my problem.
I'm not very experienced in things like this, but when I was flashing kdz to my phone, my computer wasn't able to recognize the phone with battery out, so I did whole process with battery in (and it worked)
anyway if you want to unlock the bootloader you have to update to official JB (just flash JB kdz and then wipe data in LG recovery to prevent bootloop)
so first you have to connect somehow your phone in sw mode to computer
then flash JB kdz and wipe data in LG recovery (it should be back even if you've flashed twrp)
and finally root JB and unlock bootloader (for example this way I found by two clicks here at xda, just browse Optimus 4x general category: http://forum.xda-developers.com/showthread.php?t=2251407 )
I hope I helped you a bit
I agree with you SuperLamic. Especially with this:
so first you have to connect somehow your phone in sw mode to computer

My only hope is to flash kdz file using fastboot mode. However after days of searching on XDA, installing all kinds of drivers, trying different methods etc., I'm still unable to connect my phone to PC.
Any PC I tryied so far haven't even made a sound while pluging my LG to it. Nor it's vissible in the list of connected USB devices.
So now I'm sure that a USB port on my phone is faulty There is no other possible explanation. But thank you all for your suggestions anyway.
P.S.
There is maybe a tiny chance for workaround by unlocking the bootloader without PC. But this method doesn't work. http://forum.xda-developers.com/showthread.php?t=2251407 With unlocked bootloader I woud be able to solve the problem without PC. Right now I can't install TWRP nor CWM because they require bootloader to be unlocked. CWM in ROM Manager always says that installation was successful but actualy, it wasn't. Since there is always this error when I try to load recowery mod...
[LGE_SECURITY ERROR] boot image signature
Critical failure: Unable to start kernel
Unrecoverable bootloader error (0x00000002)
EDIT:
So I find out that only JB ROMs can be unlocked. It's not possible with my stock ICS. So there is really only one solution: repair my USB port on LG to flash kdz. But I'm afraid that these days a repair will cost more than the phone itself :[
