Hi,
I have a G3 D855. It was rooted on 4.4.2, i was trying to unroot it and mistakenly erased the 'aboot' through fastboot (Totally My bad). after seeing hundred of videos and reading threads i de-assembled the phone for short pin because my phone was dead but when i plug the usb cable device manager shows 'LGE Android net'. after short pinning while the battery is out phone screen turns on displaying battery icon but i receive the error of USB NOT RECOGNIZE. changed the cables installed every version of drivers + qualcomm drivers, disabled the driver signing on the windows but still same message.
Help please. its getting on my nerves now.
Hello,
My LG G3 has had a problem for a while now, and it is out of warranty so I cant get a replacement or refund and I would like to get it working. There is currently no MAC Address on the phone, so it cannot connect to the internet or use bluetooth. I was planning on rooting the phone to try and fix this, but I was stopped when the phone wasn't noticed by my PC. It does not give me the option to change between MTP, PTP or just charge but instead shows that the phone is charging as if it were plugged into a wall. I cannot access the files as there is no phone showing up on my PC, but instead found that the phone was down as LGE Mobile USB Serial Port (COM5) under Ports in Device Manager.
I have tried factory resetting the phone but this does not work.
Any help would be appreciated. Thanks
Hello friends!
New registered user here but have already read tons of threads regarding G3 troubleshooting. Anyway, have decided to post this problem and if a similar situation has already been posted (and solved), please provide link.
For some strange reason, my G3 have decided to stay in the LG logo (I understand that this is the so-called boot-loop). This happened when the phone suddenly restarted while watching a YT vid and the battery still at 30%++. The phone just keeps on restarting until such a time that it never got pass the LG logo.
Here are the things that I have already tried to no avail:
1. Enter Hard Reset page via hardware keys (Power + Vol Up buttons). Have chosen "Yes" to hard reset device but alas, it never got pass the LG logo.
2. Downloaded PC suite, KDZ flashtool, and LGUP. Installed all three software. Connected G3 to PC and entered download mode (Vol Down while inserting USB cable). Unfortunately, unable to fully use either of the three software since the PC cannot detect G3.
Number 2 is quite strange since I have downloaded and installed all G3 drivers. This I know since a friend of mine who owns a working G3 unit was detected by the computer and can sync with the PC suite.
For some strange reason, everytime I connect my broken G3 to the computer, it is not detected by the PC and was not even listed in the device manager.
Any help and advise would be highly appreciated
I already downloaded all necessary tools (KDZ, LGUP, and flashtool) to flash the ROM but I need the PC to see the G3 unit to be able to do so.
By the way, before the bootloop scenario: the debugging (or is it developer?) options are disabled and I'm not sure if the bootloader is locked or unlocked.
I hope all this info is of any use.
Thanks a lot in advance
Have you tried simpler solutions first? Like, trying another USB ? Or another USB port from your pc? This maybe hardware related rather than software. You should try that before anything else. (Maybe you did?)

Thanks for the reply. Yup, have done those. Tried a different cable, different USB port, and borrowed a working G3 unit. The good G3 unit was detected by the PC but when I connect my broken G3 (same cable and same USB port), the PC does not detect it (not even listed in device manager).
Because of this hurdle, I couldn't flash with LGUP (it states no handset was connected). The KDZ flashtool basically says the same message.
By the way, my debugging options are disabled before this whole problem started. Could that be a reason why the PC won't detect the unit?
Dear all
My LG G3 started to get bootloop and I'm looking for a way to install TWRP that might fix the problem. I know how to install TWRP if it boot into the OS but now it can't boot. Do you know a way?
Flash it by fastboot
adb or fastboot doesn't recognize my phone. I put my phone in download mode, is it correct?
USB-debugging is allowed?
I don't know as the phone can't boot up. Therefore, I can't check or turn it on. Am I stuck?
Clearly you can't check it now. But do you remember that you made developers options visible? Anyway.
1. If USB-debugging is allowed, look on PC-side: does OS give a connect-message when G3 plugging in? ADB-tool ok?
2. Otherwise try to start over by flashing firmware.
When I connect my phone to PC in download mode, a driver fail to install (LGE Android MTP Device). I'm not sure if this cause adb not to recognize my phone.
For the 2nd option, Will my collection of data lost permanently?
1. ADB doesn't install device drivers. So take care, that OS connects correctly with G3. Then ADB will succeed.
2. Probably yes.
Bootloop is caused by hardware failure. I fixed it.
Good Day, All I tried Flashing my LG K10 M250Y with the latest firmware but during flashing the cable was loose and one of the pins didn't make contact so it stopped flashing, Now when I try to connect to LG UP it keeps telling me Uknown device, but it sees the device on com9, I am also unable to see the device on ADB or fastboot.
Turning the device on gets you to the Spinning LG circle but it gets stuck there.
I can see the device in my Device Manager LGE AndroidNet USB Serial Port COM9
Any Ideas how to Unbrick this Device, And No I Cannot Flash Via LG UP as it doesn't recognize the device.
Please please, any help would be appreciated.
Does it go into the download/laf mode?
