LG G3 not working, USB device not recognized, does not boot. - G3 Q&A, Help & Troubleshooting

Hey,
I have a LG D855K. Have custom recovery and cyanogenmod 13
Probably did a stupid thing and tried to updated something I wasn't 100% sure on...
So the phone when you turn it on the LED flashes blue and red.
Trying the factory reset, it comes up but I am unable to select any options.
Tired plugging into computer but I can't get the computer to recognize, just comes up as unknown device.
Does anyone have any ideas? I think I am going to have to bin it
Thanks. Any help will be much appreciated.

Try uninstalling LG drivers on your computer then install again. It works sometimes.

[Q] G2 stuck at boot logo no download mode no recovery device manager wont recognize

ok i see lots of threads about G2 stuck at LG logo with no download mode etc but none specific to my situation so figured id start my own.
my phone is stuck at the lg logo when i try to boot, when i try to go to download mode it shows the blue dots but windows, flash tool, nothing will recognize the phone as being plugged in, and not even the little sound windows makes when a usb device is plugged in, its been a little while so i cant remember EXACTLY what the last thing i did that bricked it was, something i did on command line with aboot something, i can try to dig it up if absolutely necessary but it would take some digging...when i try to boot into recovery it freezes at the "loading recovery screen, when i try to go to download mode it sticks at the blue dots and wont respond to anything, when i try to do a factory hard data reset it says "hard reset processing" or something similar then freezes there, ive tried reinstalling the drivers, using different pcs, read through countless threads, but have had no luck, any ideas what i can do to unbrick my brand new g2?? thanks in advance

This is what i would do....looks like your cable works, looks like you know how to get into Download and Recovery Mode. You have to get it to be detected, if it boots into Download mode it should work. Try re-installing the drivers.

with the phone off (completely), hold volume button (up i believe), and plug usb into computer. This should bring up download mode. If volume up doesnt work, try volume down. If you get just to the dots, then your download mode is broken.

Flash stock zip kernel from artmod thread.
the problem is. I can't upload any files to mobile phone. if i connect to pc, it turns on, goes to recovery, so I click on mount storage, and other mount option, nothing happens. My computer detects phone as F180L with a exclamation mark.
If i go to download mode, and then try to flash any KDZ file from all the f180 KDzs. It gives me errors.
LG Support Tool on entering serial number and model name says "check out serial number and model"
ADB never detects my phone. So I can't upload anything.
No option to upload files via SD Card.
ok, so I have no clue what happened :crying: phone was in download mode. I did nothing, but only installed LG Support Tool USB driver, while the mobile connected.
Then I installed Microsoft .net framework 4.0. And my phone is now qhs_usbdload. it's officially bricked now. I have no clue what happened. This is all that happened before I restarted and selected "reboot to bootloader" and its dead. So there's nothing left to do but throw it out
WTF OKAY! I have no clue!
But, after seeing that qhs usbdload. (i have seen that before with other phones). I complete lost any hope.
So I for feeling contended, downloaded qpst, and emmc software download, and selected MPRG8064.hex and msimage.bin.
Then like I expected it threw an error "image download failed, cookie if present not received"
so I lost hope disconnected my phone and put it there. After a few minutes thought I should try one last time.
so I connect it my pc and VIOLA it turns ON!?
now I have that same rebooting to recovery problem. I have no explanation for whatever has happened to phone in past 3 hours. I have been with phones for years. This is the weirdest thing to happen ever :angel:
Now someone, please help me?
1. Why is this in Development section?
2. You can't mount internal SD as USB storage. Use adb push or adb sideload instead, that will help you to get the files onto your phone.

Some user got that problem before. I am not sure about how they solve it but I guess that they flash their original KDZ back. If your phone can enter download mode, you should try LG Flash tool 2014 and flash your original kdz to restore incorrect system image.
About adb cannot find your phone, try to remove adb driver from device manager and reinstall LG usb driver.

My phone is acting weird. Sometime it would start. Sometime the red light would blink. Sometimes the red light wouldn't blink at all. Then sometimes, it starts. And then it doesn't.
I have no clue what is going on with it.
But it went to download mode many times again, it would go to fastboot, bootloader, recovery etc. Then sometimes it will not respond to any buttons at all! I know its battery is down, but idk if it's charging or not?
I don't know how to know whether the phone is charging or not. I left it charging for 30 minute, and it didn't even buzz. :crying:

One thing you can do (I've done it in the past a couple of times) is to crack your phone open, disconnect the battery, and charge it with an external charger. That would at least give you a full battery to start with...
Regarding the charging problems, I had that once. I was able to startup the phone by simply using a 2A charger instead of the LG's 1.2A.
When I had this issue it was charging while in recovery. Please look at this post and flash your kdz.

thanks. but after charging it. I couldn't turn the screen off because it goes in recovery. I turned off the phone after good 30 minute charging. Then went to sleep. And in the morning I connected it to pc. by holding volume buttons for download mode. It didn't go to download mode. Only it's red light is blinking. and no display.

Hi, regarding that. I was able to sideload exitrecovery.zip file. It goes to 100% then nothing happens. Nothing happened on phone screen as well.
And can you send me link to that stock zip kitkat? i have a miui.zip and few other roms that I have not tried. thanks
Edit: also what should I do about adb, am i doing correct?
Becuase in adb devices, my device is displayed with deviceID sideload
And i have only pasted adb folder, with a dll and a zip file, there is nothing else, do I need to install SDK?
I tried lg flash tool 2014 again, and it flashed, I swear yesterday I tried to flash it, and after clicking on it, it never showed me country and language selection menu, so it would sit there and do nothing. now I don't know how but it did it :laugh:
thank you so much you'all

[Q] Boot loop: Can't enter Firmware Upgrade mode

I'm posting a question as I've spent days searching with no luck.
I have an LG G3 that while in normal use got very hot and turned off. Now it gets stuck at the LG logo and doesn't boot. I tried a normal factory reset but this just goes back to the LG logo and nothing happens.
So I'm trying to get into the download mode "Firmware Upgrade" screen to flash the stock rom. I hold down volume Up, and plug in the USB and it gets to the little "Download Mode" icon but does not continue to "Firmware Upgrade" and the computer (I've tried 3 different systems) wont recognize the phone.
Interestingly at some point while being in download mode it switched to fastboot, I have no idea how this happened but I was able to run commands on the phone using fastboot.exe, however I have not been able to get back to fastboot since.
Also I'd really like to be able to recover the data on the phone.
Any help would be appreciated.

Thanks I tried the drivers you've provided but still no luck. The computer won't detect the phone at all, it doesn't attempt to install drivers nor does the phone show up as a generic device.

I hope not, this phone was purchased in Media Markt in Germany and it's not covered by warranty here. LG Australia said it would cost up to $260 for them to fix it and the phone could possibly be downgraded if the mainboard needs to be replaced. I don't know if it would be possible to claim the German warranty.

Soft Bricked? Hard Bricked? Lg flash tool wont work... cannot get into download mode?

Hi i have a D85010f that is running 4.4.2 on TWRP 2.8.0.0.. i was in the middle of downloading a rom with no OTA and AN OTA popped up saying that it will begin in 30 seconds. I quickly shut the phone down and now it will only boot to twrp. i cannot factory reset or flash another rom. I cannot get the phone into download mode. My windows 7 device manager will not show me anything related to port settings to change to COM41. i can usually fix my own problems but this is ridiculous. This phone is 4 days old. Am i missing something? apparently some BOIS do not unlock the ports in windows 7 or something? This is such a headache/
CAN ANYBODY HELP ME BEFORE I THROW THIS PHONE IN THE GARBAGE?
so i got it to say factory reset status 2. the drivers keep installing and then failing and working for a second then failing again. W T F. how many/ what drivers do i need to get this **** running. i switched the COM to 41. but the MTP device driver keeps failing. WHAT DO I NEED TO DO THIS. ive ruined my whole afternoon on this ****ing phone its really annoying how finicky this whole android BS is. Truly.
really helpful community we have here.
kill the thread i figured it out. but now am running d85010d idk if thats bad or not
sreent shoot driver i see and sreent shoot lgflashtool flahs error

I followed this video step by step. lgg3rootdotcom; the video thats says "how to unroot/unbrick lg g3" you have to dl the lg flash tool and have the lg g3 MTP drivers, then DL the stock rom for your device (d850 51 ect). set up the COM41 serial connection through windows. YOU CANT GET THE PHONE INTO DOWNLOAD MODE UNTIL YOU HAVE THE COM41 CONNECTION ANNND THE MTP DRIVER!!!!
as for battery not charging... that never happened to me. maybe plug it into the wall not the usb of the computer.

I think I might've hard bricked my phone!

I tried uninstalling xposed from my phone by recovery and it caused my phone to go into a bootloop, I entered recovery and tried to do a factory reset to see if that'll fix the problem but now my phone gets stuck on the "SONY" screen and I can't get past that. Even connecting a USB to my computer doesn't detect it, Is there anyway to fix this? :crying: :crying: :crying:
Get flashtool if you don't already have it, then download the firmware for your exact device model, then click the Lightning button and then follow its steps
I've tried that already but my PC doesn't detect the phone, I can't even get it into a fast boot mode. It only charges my phone when I connect a USB. Edit: It's fixed now, I was using the wrong USB. Thank you!
