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, I have a Verizon LG G2 that is stuck in download mode. I was trying to unroot my phone using this method:
theunlockr(dot)com/2013/10/31/unroot-lg-g2-verizon/
Then, at step 12, where it was flashing the stock image, it stopped and got stuck.
I have tried using the LG Mobile Support Tool to restore my phone, but the process gets stuck on 10% and gives me an error. I have tried to install the drivers, but adb never recognizes my phone. I have a second LG G2 that adb did recognize, but it doesn't recognize the one in download mode. I am unable to access recovery via adb or button combinations. Every time i turn the phone off it goes straight back into download mode only when it's plugged in, otherwise it goes black and the only thing it does is vibrate when I hold down the power button. I don't know what else to try, what should I do?
Thanks.
Edit: the LG Mobile Support Tool recognizes my device as "LGVS980" and the Software Version as "VS98024A."
I attempted to get twrp via autorec awhile back and had issues. I thought all was reverted but when this 27a update came out it bricked my lg g2. It boots to the LG screen then nothing. I can hold down power and volume down and get to factory reset but does nothing when it is accepted. Windows 7 PC does not recognized the phone as being plugged into USB. I can not get into download mode. Am I screwed?
Exact same issue

Mine did the same thing about a week ago. I downloaded the LG download recovery mode files and transferred them with a Linux computer to sdcard of phone. Then when I tried download mode it showed up on my Windows 8 computer running LG support program and return the phone to full stock. Then just root again with stump
after flashing the material concept and twrp the phone booted up normally i installed all my application and rebooted after reboot the phone blocked in the startup screen ''launching applications''
I tried to connect it to the computer with flashtool but does not recognize it . what can I do?
Hello everyone. I am in real trouble here and I will explain why. I have recently tried to get the custom recovery with a locked bootloader (philz touch) on my device by following a thread. As far as I know I followed the guide properly but when my device rebooted it bootlooped 10x and then when my device booted it froze at the lock screen and restarted. now my device bootloops several times before boot and once it boots I get 1min at the most before it freezes and restarts. Also sometimes it fails to boot at all and it gets stuck in an infinate bootloop and I have to pull the battery. when I connect it to my laptop with a usb cable it is only recognised if the device boots but I only have a few seconds because the phone reboots and disconnects when I try and enter recovery or download mode my screen goes black and the only way to get of this is to pull the battery. I have also tried to connect to my laptop when on this black screen but i have had no success. If I turn the phone off and connect it to my laptop via usb when I am on the "battery charging screen" it appears on my computer as a unknown usb device. i do have all the drivers ect. my device is rooted with baidu root if that helps. ive heard of a little device called a usb jig would that be useful to me? sorry if this is not worded very well or looks like a book. Im not a idiot but not quite "tech savy" i would like to think i am somewhere in the middle. I have been using this site for years for various devices and always managed to succeed. help would be apprecited. Thanks
UPDATE: I have tried to factory reset from the settings but for some reason the button is greyed out and it wont let me press it! also I cannot connect to wifi or mobile data these are greyed out aswell and when I try to connect via the sliders in the settings menu they are also greyed out!!!

Hi, you need an unlocked bootloader for it to work properly. You can find how to unlock the bootloader by going to Sony's website and see where it says to unlock the bootloader or just look for it on Google. To get back to the stock rom (Android 4.4.2 KitKat), you will need Flashtool and the stock rom. You can find the rom on Google by just typing "sony xperia e1 d2005 stock rom". To get the recovery just try looking for it on XDA. And USB Jig will not work for Sony devices. USB Jig is only designed to work with Samsung devices.
