I'm hoping someone can help. I have an LG G3 D855 phone and is factory unlocked and running Lollipop 5.0. When I first got the phone (second hand), I was able to connect the phone via USB to my PC and was able to transfer files back and fore no problem. Until about 3 weeks ago, I am now unable to do this. The PC won't recognise the phone at all, all the USB connection does is charge the phone and I can see no option to get the phone to change to file transfer mode.
I had a look at Storage in the settings menu and I don't have the three dots that some people have spoke about. I have factory reset the phone and this hasn't fixed it.
I have tried using a different USB cable, this was the same. The drivers are installed (phone was recognized before). I have also tried the LG Suite, again same result. I also had a look in Device Manager for ACER something or other and this wasn't there.
I am currently having to use Bluetooth to transfer files back and fore to my PC and this is a bit slow. I'm assuming that an update LG have done has somehow broke the USB settings. I am also unable to root the phone (tried this before the USB stopped working and nothing worked) and possibly go back to KitKat 4.4.2 to even try that.
My phone has software version V20u-EUR-XX, Kernel Version 3.4.0 and build number LRX21R.A1439960697. There is no update available for my phone in the Software Update center.
After quite a bit of searching, it seems that this is a common issue but I have not found a solution to this. Can anyone help? Is there any firmware or software that I can try?
Thanks.
Assuming the OS is Win8/8.1 or Win10, have you already tried this?...

Thanks for the reply. I am using Windows 7 Home Edition 64 Bit and had had a look for the ACER Composite ADB Interface in Device Manager and it wasn't there. Post #18 in the thread you linked to, I have no idea what kdz file I would need. Does this method need the USB to working?
Thanks for the reply and help.
I have D85520T_00.kdz and D85520U_00.kdz files. Can someone tell me if these are OK for my phone (and latest) and what the differences between the two are (apart from the file names?) Thanks again.
I couldn't tell you what the differences are between software revisions, only that 20u is newer. And I believe 20w is the latest available. I would probably try reinstalling the latest drivers from LG...

... then again check to see if your PC recognizes the phone. If the "Charge phone--> Tap for more USB options" notification doesn't appear after installing the latest driverset, I'm not sure what else you could try. The LG Flash Tool needs to be able to communicate w/ the device when it's in Download Mode. You might be able to find something in the [Guide] LG G3 Stock Firmware (Go Back to Stock) KDZ & TOT Method thread related to the same problem you're having.

Just a quick update, can't even get the phone into download mode. I press volume up, insert the USB cable in to the PC and all I get is the battery charging icon. I'll have a further look this weekend - not good so far!
Thanks again for the replies and help.
Firmware W seems to be flashable only via TWRP or ClockWorkMod just now?
I have been able to get the phone into Download Mode a few times (not all of the time) and when I run LG Flash Tool, it just tells me that the phone isn't connected. I'm going to assume that the USB port is in someway defective. Can't think of anything else.
Have you tried w/ a different PC and/or OS? Have you tried connecting the phone via different USB ports (USB 2.0 compared to USB 3.0 or vice-versa)? And I assume you've already installed the latest driverset from LG?...
http://www.lg.com/us/support/software-firmware
Yes, I got into Download Mode once or twice on the laptop. I'm using LGMobileDriver_WHQL_Ver_4.0.3. I have tried USB 2 ports on both my Laptop & PC. I've tried driver 3.81 as well.
OK, got a new USB Charger port fitted just in case it was the port that was wrong and it's still exactly the same! I did a factory reset and have setup the phone for now. During the factory reset, it does pop up with Updating Android and has 169 updates. If anyone here has the LG G3 and has it working file transfer wise, can you tell me what version of the LG USB drivers you are using? Is it possible an LG update has caused this?
Thanks.
It's fixed!!! I think there was an update yesterday for Android Devices or Services, can't remember which was made available yesterday, installed that, reconnected the phone to the computer just a few minutes ago and it has finally been recognised! I can finally transfer files between the phone and the PC.
It was an LG update that has fixed this.
At last.
I'd like to say thank you for all the replies and help.
Hello.
I just tried to root my device and it seems I ended up soft bricking it.
I hadn't used it in a while and it was running 5.0.3.1 I did firt try the KingRoot method without any luck, it just failed. And since I had an USB A-A cable I wanted to try that. Everything went fine install_firetv2_recovery.bat ran successfully I got TWRP installed, flashed successfully sloane-5.0.5.1-rooted_r1.zip checksum was included and okey. It boots I can navigate it, but shortly after if freezes with a message that it's going to update now, so I assumed it had downloaded the new update in the background while I rooted it, blocking the amazon update servers in my router did not help, still get the message, taking it offline render the device useless. And I noticed it still had all the apps I had installed from before I rooted the device that I could wipe the update it had downloaded by resetting the device, I went into TWRP did a wipe, it said it had problems remounting and when I then rebooted I stuck at the white Amazon logo. I've tried the Alt+Print Screen+I method to fix it without any luck, I've tried Ctrl+Alt+Del, without any affect, and since the keyboard I connect to it do not light up I assume it's not initialized for keyboard input.
Anyone have any idea what I can do? :S
Edit:
I have also tried to run the install_firetv2_recovery.bat again after the issue occurred. With USB A-A cable connected but it say "error: unable to find target file" after "Reading 04EDFFF000" tries this one more time and then when it get the error again gives up and give me "Press any key to continue"
Edit2:
Also tried this fastboot method without any luck, it does not show up under fastboot devices (maybe I had to do something else to have this enabled?)
Isse has been perfectly solved with rbox's FireTV 2 Unbrick Image guide
I received this from a friend because it was bricked after an update ran against its custom ROM.
I have tried everything to restore it, but nothing seems to work. It starts up but only gets to the Amazon TV logo and just sits there. Here's what I have tried so far:
1. I connected it to my laptop via an A-A Male-Male USB cable, but my PC doesn't see it so I can't push anything to it via ADB.
2. I connected it to my network, but it doesn't pull an IP address so I can't push anything to it via ADBLink.
3. I tried using the remote to force a factory reset using back arrow and right, but it doesn't see the remote so that doesn't work either.
4. I connected a USB keyboard to it and used Alt+PrtScn+i to force it into recovery mode, but it only display a system recovery screen and doesn't give me any options and doesn't do anything when I press the "Home" key.
Any advice on restoring this Fire TV would be GREATLY appreciated:laugh:
My new Elements Fire TV doesn't update... now still version 5.2.5.0, whereas it should be 5.2.6.2.
It doesn't do it automatically, and nothing happens when I make it search for an update.
I was told by Amazon customer service to update it manually via USB port. It didn't work.
Anyone experienced the same trouble, and has any idea how to fix it?
What were the instructions that Amazon gave you to update via USB?
I downloaded the updated on my USB, and when I plug it in the TV USB port, the TV should upload automatically. But here nothing happens.

I tried that too, without luck.
I used this update: http://www.aftvnews.com/amazon-fire-tv-fire-tv-stick-software-update-history/
I am having the same issue. The tv detected the usb drive one time and then I encountered an error and it would not load the update. I tried downloading and running the updates on the link provided above but have not had any success. Anyone else have other suggestions? The TV is so sporadic and buggy now that it's almost unusable.

Yes sir i did extract the bin file and placed it on my USB, I tried it with a 8 GB USB Fat32.. Tried it on both USB 3 and USB 2 ports on TV.. It recognize my USB as a MEDIA PLAYER, but when i try to manually do software update from USB it shows the message " NO AVAILABLE UPDATE FILE , PLEASE INSERT USB DEVICE OR SD CARD WITH SOFTWARE PACKAGE"... I also tried to open the media player and open the bin file but it said I don't have any application to open it.
Try this.....found in older TCL pdf....
"Please save file ‘V8-xxxxxxx-LF1VXXX.bin’ at the root of the USB drive formatted in FAT32.
Put TV on standby.
Insert USB drive in ‘USB’ slot of the TV.
Press and maintain the power button of the TV until the front LED blinks.
TV will update SW automatically, and shows popup menu to inform the user is updating."

Repeat same until press and maintain the power button on TV (not remote !)....until the front LED is blinking.
As soon as it started blinking, you can release the button (take out your finger from the button).
TV will update SW automatically, and shows popup menu to inform the user about the ongoing update......
Upgrade will take some time around ~7 to 10 minutes.
Do not switch off, unplug the power cord or remove USB drive until upgrade is complete.
When reflashing is successful, TV should restart automatically after 5 minutes.
Remove the USB drive from the USB port.

Try V182 OTA file by local update in setting (or power button).
If same , try different USB.
