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.

Like the title says:
I just tried to upgrade my Optimus 2X via PC software. The package downloaded fine but in the middle of the upgrade process the PC software crashed(!) and now I have a phone which is stuck in the upgrade boot screen saying:
"S/W Upgrade
Please wait while upgrading..."
So, what now? Any way to get this thing working again?
First, remove your battery and put it in your phone. Boot the phone up and see where it goes. If it goes into S/W mode again, that sucks. If it goes to the LG boot screen, put the battery out again and put it in. Press Power + Volume Down buttom to go into the CWM menu. From there you can restore your backup (if you made one) or mount the SD card and put the (rom).zip file in your SD card. Then just flash the zip from the CWM.
The update process by LG is pathetic. Many a times, I had the same problem as you. It would just get stuck. It is because of faulty drivers on their part, unable to maintain a connection with the phone.
You can try to NVflash clockwork mod recovery (CWM) and then recover your data.
i have the same problem.
i've tried everything without luck.
mine stopes att 4 procent and pc is trying to install some new device
lge mobile composite usb device.
there is no way to work around this issue.
i have tried absolutly everything.
wipe, clean, drivers this that. hard reset, variations in installing, i don't know what else i can do,
this is the message that cousing all of this.
this is located just in upgrade mode
the device is called
LGE mobile composite usb device
Universal Serial Bus controllers
LG Electronics Inc.
Location : Port_#0001.Hub_#0004
Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)
Thanks for the infos. I managed to install a stock rom and baseband with SmartFlash yesterday. Just a few minutes ago I used LG's update tool to update the phone to Gingerbread.
So, problem solved. If anyone has the same problem, follow these instructions to update the baseband:

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 :[
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??
Hi,
Am a novice when it comes to rooting, unlocking android devices. So please excuse my ignorance and my long-winded style of writing. I want the expert users to educate me on this issue and so I don't want to miss any trivial (or not so trivial) information.
1) So, I got Samsung gear live from ebay. It came with a sprat-userdebug 5.0.1. After googling I found out that it's a user/refurb build and can't be updated to 5.1.1
2) Thanks to rootjunky! I used Gear live restore tool V3 and unlocked the bootloader (option 2). Faced few issues in getting the driver. However, fixed everything and unlocked it. Flast TWRPd it (option 8). Flashed recovery (option 4) and bootimage (option 5). Then I sideloaded stock image from 4.4W.2 (using boot.img and system.img). That was the version I found after googling.
3) Then I tried to update it via OTA download. Download completed and it went back to recovery mode and did't apply the download. There was an error message that said something like "Unable to verify the download"
4) Tried multiple times and no luck with that
5) Then tried to sideload new version 5.1.1 LCA43 from xda wiki page. However, when my device went to recovery mode, my pc lost the connection and i wasn't able to sideload (received - device "null" not found" - error from adb command)
6) Until this point I was able to pair my device with my samsung S5 phone and only problem was not able to install the update
7) Then I reset my watch to factory setting, restarted multiple times, went to recovery mode to boot as a new device etc. No luck
8) Then I did something I shouldn't have done (or I think I shouldn't have done). Used option 7 root gear live. When the system went to SH mode, I panicked and closed the cmd prompt and hard reset the device by holding power button
9) After this step, I was not able to pair my device with my phone. Now the version says 4.4W.1 - KGW42N
10) Tried resetting my device, restarted it, used recovery mode to restart it, revoked all debug access, deleted adbkey from my PC, uninstalled android SDK, all drivers, etc. Reinstalled it again with no help.
11)Suddenly android wear in my phone sees my wifirouter as a device (strange)
11) When I plug in the device to my Pc, I could see it in my device manager. When I use recovery tool it says unregistered device and asking me to register it via my phone. Where as am not able to pair it with my phone. Tried to pair it with a new phone (moto e) and no help either
12)Somewhere read that disabling wifi in the phone before pairing works. Tried that and no luck
So here am with a bricked device that stays in the screen where it says "install android wear in your phone" and detects nothing else. Am able to go to bootloader mode, recovery mode from the device. However when it's in recovery mode, my PC doesn't detect it. Even the recovery tool says unregistered device.
Please help in unbricking this device and thank you for reading thru the whole problem. Any help would be much appreciated!
Use Gear live restore tool v2. Lots of known issues with v3
Thanks for the reply. I will try this. However, how will I make my device discoverable? Now, none of my phones detect my device.
So I guess I will get "Unauthorized Device" error when I use recovery tool. Could you please let me know if there's other way around? Or am i missing something?
I've never used it
Pretty sure all the info you need is in the thread
http://forum.xda-developers.com/gear-live/development/utility-gear-live-watch-tool-t2846696
No luck. Tried V2. Tool doesn't recognize my watch. It says 'Device Unauthorized. Please check the confirmation dialog on your device'. My device is stuck in 'Install Android wear on your phone' screen.
unbricked using v2 of the tool. Now trying to update the os version. Will see if I can get lucky this time. Thanks for the help!
All is good now. Now my gear live is running on 5.1.1 with latest updates.
Good work
Please can you tell what exactly you done, as I'm on the same root.. and I'm using win 10... but without any luck so far..

Simple procedure.
Just download v2 of this tool
Make sure to install USB drivers
Unlock bootloader - option 2
Then use option 6 to flash it. Then you'll get new OTA updates.
Refer rootjunky video - https://www.youtube.com/watch?v=x7oRjESQh_o
I'm not able to pair my device with my phone. Now the version says 4.4W.1 - KGW42N,
and ... I tried V2 and V3. Tool but doesn't recognize my watch. It says 'Device Unauthorized. My device is stuck in 'Install Android wear on your phone' screen.

Follow this procedure.
1)Make sure all drivers are installed properly in your PC
2) Make sure when you connect your device to your PC, it's discovered as unauthorized device. It's ok
3) Long press power button in the device and swipe from top left to botom right corner when you see samsung gear live logo
4)This will get the device to bootloader mode
5)Now connect the device to your PC and run V2 of the tool. Your device will be discovered in fastboot mode
6)Now select option 6 to flash the device to stock. It'll flash it
7) Now swipe down to highlight start and swipe from right to left to start. If it goes to Raw dump code = 6. do a hard restart by long pressing power button. You'll get back your device in original setting.
Check rootjunky youtube video to get the live demo of this procedure.

How did you get past this? I'm stuck here now too.
-- update after trying that procedure again, it worked to get to fastboot mode. Now I'm doing that 'option 6' to flash it.

sounds like USB driver issue. Please install correct drivers and follow the steps mentioned above. It should be unbricked.
Where can i find correct drivers? Additionally my Gear Live doesn't turn on and has only black screen.
I am confused on how to use the tool. My watch is stuck at the Install Android Wear App and won't do anything short of turning it off. How do I enable developer mode \ debugging without being able to get to the watch settings. Please help! Thanks

You need to factory reset first of all. After that let connect to your wifi, the updates will download on their own. They put a new one out today. I can't go into how but if you look at the forum and search the answers are there. There's even a tool to use.
