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

Gpad bricked, what can I do?

I have been trying to get this thing upgraded to 5.0 for a day and half now, and i just flashed it for like the 10th time with lg flash tool to try to take it to stock. The rom i flashed that bricked the device I found in this thead: http://forum.xda-developers.com/showthread.php?t=2698267
All of a sudden it won't turn on, won't respond to adb or enter recovery with the volume down + power combo.
All i can see in device manager is qhsusb with an exclamation point. I struggled to update this and once i finally did, the device still isn't recognized by the computer in any lg programs or by adb and wont turn on What can/should i do at this point??

I managed to find out that the phone is in something called bulk mode and even found a tool that gets lg phones out of bulk mode. The program located in this thread here: http://forum.xda-developers.com/lg-g...s-usb-t2933830.
It has my chipset in it(The APQ8064) and can connect with the phone. It passes the first two tests (AP, and EMMC) and fails the SDRAM test. If i can figure how to fix the last test and make it succeed, the tablet won't be bricked anymore. Any ideas?

Help recover completely bricked G3 (D855)

I was trying to put TWRP on my G3 (D855) but it failed for some reason but the stock recovery was deleted. So there was no recovery in phone. I gave it to a friend to try putting TWRP in it, he also failed and somehow corrupted the partition. He said the phone is completely bricked now and is not even turning on.
Any suggestions what I should do?

Too few details provided.
Can you enter download mode?

How? Which tools to use?

Its neither turning on, also no LED light when I put in the charging cable with adapter. When I plug it into laptop USB, it shows "LG Android USB Device" in Device Manager - with yellow exclamation mark. Please help.

I noticed one thing. Even though on the cover it says D855, but when I opened the phone, on the mother board I saw D851. What does this mean?

The motherboard should be right, its tmobile. Did you have fm radio on it? If not then tmobile for sure

(i installed slb1 without battery and then unpluged phone, put battery, hold volume up, putted usb back into phone and tried to put phone into download mode. IT WORKED!! )
And Thanks for replay

I was in the middle of unbrick my g3 from hard brick to soft brick. I flash firmware using lg up at 99% then the phone died as it tried to reboot. It won't boot at all. As you said when remove the battery and connect charger, i can see my motherboard working with exclamation mark. As soon as i put the battery, motherboard out and no sign of life. Is this sign of bad battery or what. I don't have spared battery

I recommend first, to users with similar problems, to try first my guide in following link and after the pins in motherboard-tot files

I have D858HK hard bricked for 2 month and i use v10d to flash every partition. Then it won't boot into recovery. When i use v985 .tot, it successfully boot into recovery. Also on LG Smart Board diagnostic, my model not detected. Even if i manually select, nothing happen when it reboot. Right now, i have no idea whats wrong as i spent countless of hour on google and XDA.

I already follow your guide. The thing is, my device not detected on LG Smart Board Diagnostic. When i manually select my device, everything ok then it boot with blank screen with red and blue led. I can't even enter download mode. I use win 10 64bit with all driver installed and disable integrity checks and everything

LG G3 not responding ( no boot, no download mode, nothing)

I was hoping someone here could offer me some guidance on what to do.
I've got a LG G3 D855 (international)
So I tried putting TWRP on my phone as a recovery but I must have done something wrong.
My phone isn't booting at all. It's not even responding to putting a usb cable in. Only if I connect it to a usb cable without battery it shows the logo that I don't have a battery inserted.
Did I completely destroy my phone?
edit: My phone is now showing up in the device manager as a Port(COM LPT)

I think you flashed the recovery image as boot image. Get the boot.img from your original Rom and flash it as boot image in recovery.

The phone didn't make a connection to my computer and was not recognized by fastboot, etc.
But I've just received it back from the store and they repaired it.
Thanks for the help!
