Hello. I have a strange new problem on my phone. I have very slow charge with my charger original device, and fast charge with USB which connected only PC. Power-bank have same problems. I installed too much 9.0 roms and all have same problems, reinstalled kernel, original kernel, updated TWRP, installed and non installed Gapps, etc...
Sometimes i can fix this problem on one time, on/off original power save function, and in custom kernel changed settings fast charge from usb.

Hey guys, just want to root my LG G3 (never rooted before) these day but failed for many ways. But computer said the MTP is not working while I entered download mode (code 10 error). I have tried a lot of way to solve the problem but still not success. Mine is in 5.0 with software version V21A. Someone told me V21A is unable to root. Is there any solution to it? Wanna downgrade back to kitkat cuz 5.0 drains battery in really a short period of time.
Hi, be sure to install the right mtp drivers for your phone. Do a quick web search on that. Also, disable any antivirus on your phone and make sure that you use the right usb cable. Some usb cables are not designed for data transfer - just for charging. The stock cable should work.
Hi. I was using G3 D855 on stock V30H (rooted, with TWRP) Yesterday i've connected my LG to pc via USB, but it only charges. When i disconnected phone it still was charging (flash on battery icon)need to reset. Same on original G3 charger. I was thinking thats a Rom error so i've flashed newest clean Fulmics, but the effect was still the same! Next step was flashing KDZ with LG Flashhtool. Phone was not detected when i plug usb when phone in DOWNLOAD MODE. My phone is on warranty.
Here's the questions:
1. Can i fix that, or is that hardware problem?
2. If it's hardware problem can i go back to stock with stock recovery via TWRP without using LG flash tool?
3.If no, can LG cancel my warranty because i'm rooted and on custom rom?
Sorry for my english.
Please help me
Try USB OTG cable, if the usb doesn't get powered/recognized then the usb port is probably dead. Also under dev settings theres USB options, check if its not on charging only.
Hi everyone! First i'd like to apologize for any english mistakes, since i'm brazillian! Here's the thing... Recently, i`ve updated my LG G3 with a 6.0 Marshmallow rom (from lg-roms website), and after some tests, i've decided to go back to 5.0 Lollipop. But here's the problem: when i tried to load the new room via lg flash tool, i get some errors, saying that my phone is not connected (just when i'm in the download mode). When i try to flash with the phone on, the lg flash tool recognizes him, begins the installation and reboots the fone to the download mode, but when the download mode initializes, the software shows the same message (that he is not connected). Also, i`ve tried to root the phone with kingroot (a bunch of versions) and i never get succesful. Can anyone help me with a solution so i can go back to 5.0?
Thank you gustavorossy for your post,
Same problem here. In addition, to make the phone recognize the pluged usb, I have to :
1- turn it off
2- plug the usb cable
3- turn it on with the cable pluged
Otherwise, if I turn it on without the cable pluged, or if it reboots during utilization, the phone don't detect the charger nor the PC or any other connection, till I follow the steps above. So it makes it impossible to go stock for exemple.
Except it, everything is working well and I tried to install various custom ROMs none of them fixed the problem.
Thanks a lot for any help.
hey everybody!
i was using my galaxy a3 2017 (SM320FL) for half a year with lineage os (15.1) and flashed the latest build (Lineage 15.1-20180821-UNOFFICIAL-a3y17lte) some weeks ago.
i allways noticed little bugs etc. but all in all it worked for me.
since a week now, the phone won't boot into the system anymore if not connected to charge. i can still boot in download mode and recovery without plugging it in but not into the custom rom. as soon as i deconnect it (when using the custom rom) it reboots and gets stuck at the samsung screen.
that wouldn't be that bad if the usb connection was not dead as well. that happened a few month ago allready. i tried to connect it via odin, kies and smartswitch in download mode and recovery. but nothing. i also reinstalled the drivers via kies. i also flashed "ressurection remix oreo" to check wether it works with different roms but it didnt.
does anybody here have an idea what i can do to make the usb connection work? or is there a possibility to flash the firmware without it?
device SM-320FL
Android 8.1.0
TWRP 3.2.3-0
Bootloader: 0x030c (?)
EDIT: the problem turned out to be broken cables. i tried with a third one and usb is working fine.
Is there anyone who can tell me why my phone shows 0 percent battery after installing any pie rom and also it doesn't connect to charger and pc.?
I also got the same problem, I fixed it by installing the stock ROM
