Right, so I got myself an AT&T LG G3 D850 from eBay refurbished and unlocked. And I'm pretty much in love with the device, but sadly I'm having some major issues with it.
First off, it absolutely refuses to switch to MTP or any other mode when connected via USB. The USB configuration seems stuck in Charging mode. I've hunted through the XDA forums again and again for a solution, but none of the ones provided have worked. I've tried several different cables, factory reset, several ROMs with no luck. If you plug the device in while it's turned on, whether to a computer or wall socket it won't even charge. In order to get it to charge I have to power off the device, turn it back on, connect the cable on the LG boot screen, and then it will charge the battery. I'd assume at this point its a bad USB port, but why would it still be charging at all if that is the case? Which leads me to believe this is related to my other problem...
I rooted the device with King Root successfully, installed TWRP manager and flashed the latest TWRP for my device. Since then I get an error screen on boot that says "Secure boot error 1003". When the device is turned off, it flashes between a screen with a battery icon that has that same error message on it, to the battery charging screen.. shuts off the screen, then does the process again. So the only way for the device to charge is the above mentioned method.
Just today I discovered that apparently the bootloader on these devices needs to be unlocked before flashing (no mention of this was found in the rooting instructions I followed). I'm guessing this secure boot error message is because my bootloader is still locked? Could this be the cause of my USB connection issues as well?
Currently I have a CM 13 nightly installed with TWRP and other than the above issues, the device seems to work fine otherwise. Before hand it was on stock Lollipop. Between all the threads I've read about this, I am just straight confused and lost at this point. I apologize if this is a re-posted issue, but I can't seem to find any info about it otherwise.
As a side note, I discovered the cable they shipped it with is damaged and doesn't work. I'm using the cable for my old Samsung Galaxy S4 (SGH-i337 - Canadian model). Could that also be an issue?
Thank you so much for any help! I really like this phone and I want to get it to work.

Sorry if this is something that has been covered before. I searched, and searched and didn't find my exact problem. Any guidance you may have, including links to the appropriate threads is greatly appreciated.
My Q shutdown today while it was sitting in my pocket during a meeting. It was way too soon for my battery to be dead, but I tried charging it, both by USB on a computer and on a stock charger just in case. The backlight on the screen comes on for a few seconds every minute or so, regardless of whether its on hte charger or not. The screen is black otherwise. The battery is HOT, even after being off the charger for a long time. I tried soft-reset and booting into recovery with no luck. Plugging into USB on a computer that has Moto Device manager installed results in the computer alternating between recognizing and not recognizing the device every few seconds (seemingly in concert with the backlight turning on and off) but it does not recognize it long enough to load directories, etc. RSD lite will not recognize the device.
I wasn't doing anything with the phone at the time. It is rooted but not unlocked.
Any ideas? Will I run into a warranty issue since it was rooted even though it's not unlocked?

Have you tried to force reboot (Vol down + Power button for about 7-10 secs)?
Yes. Thanks for the reply. That's what I meant by soft reset. What the issue, I figured out, was that my battery had decided to self-destruct. It didn't have enough charge to even boot the phone successfully, so it was not possible to put it into recovery mode or anything else. I took it to Sprint and they replaced it under warranty.

I have an AT&T Note 3 SM-N900A. I Installed X-Note Rom on it a while ago, but I recently have been having problems charging the phone and was going to take it to an AT&T Device Support Center to fix it. I tried to install the stock firmware N900AUCBMI9 using Mobile Odin, only to see the a boot up screen that says "System Software not authorized by AT&T has been found on your phone . Please turn off your phone and go to the nearest AT&T store for help." I tried to get the phone to connect to Odin on my Windows PC, but the computer will only say USB Device not recognized, and it won't show up in Odin at all. The weird thing is that it says USB device not recognized even while the Note 3 is off. The phone also stays on while in Download Mode when connected to USB with no battery.
I was wondering if there's anything I can do to at least ensure that the people at AT&T can't power up the phone and see this message. I should have just left it on the custom rom, this looks way worse. I'd rather have a hard brick at this point, at least they wouldn't be able to see it was rooted and flashed. I really screwed this up, if I knew I'd be having issues I would have never rooted it. Any help would be extremely appreciated. Thanks for your time.
Dear community,
I have a serious problem with my beloved Nexus 5 (black, 32GB).
Yesterday I recognized that the Device doesnt detect any kind of USB-connection.
Neither on a charger, nor on a computer/notebook. I tried several different cables and computer/chargers, but no differences.
When the device is powered off everything works properly. The Nexus is charging and I even managed flashing Android 5.0.1 via fastboot a few minutes ago (hoped that the system was the problem, but it doesn't seem so).
Device isn't rooted or modifed (recovery, system) in the moment cause of the os-flash.
Do you have any idea what the problem could be? :crying:

Hey @BrainChecker
first of all it doesn't seem to be a Hardware defect, if it's working fine, when phone is off!
Seems like u created some kind of problem with connecting to ADB or any update etc...
I would recommend to backup all stuff u need and then going to recovery and make a factory reset.
If all is working fine u already see there was a problem in system.
If u have still problems, it seems to be deeper (but don't think so), which means kernel, bootloader etc...
Much success!
CHEERS
Thx for the fast reply
I reflashed Android 5.0.1 now, but I have still problems.
Now, the device is charging normally, but still doesnt connect to computer. And the charging symbol doesnt disappear when I plug my Nexus off...

So check ur source for firmware and there's also the 5.0.2 out.
Try to flash this with a clean system.
Much success.
CHEERS
Thanks. Source is the official Google-Site for Factory-Images, MD5 is okay.
Where did you find a 5.0.2 for the Nexus 5 ? I'm finding only one for the Nexus 7.
Problem still is the same (Sytem reflashed), and even with a custom-kernel the are still there.
I'm really scared
EDIT:
a little bit more information. I reflashed 5.0.1, made a factory reset and even reflashed 4.4.4 (of course with a full wipe). Still problems.
Deinstalled all USB-Drivers (with USBDeview), changed the used ports on my computer and my notebook.
I tried custom kernel (hellsgod) and recovery (TWRP), no changes.
Still same problem. Phone is charging when plugged in (in the some cases, but NOT in every case). Charging symbol doesn't disappears after plugging off.
Computer doesn't detect anything. Neither in system-tray, nor in the device manager. But I recognized that for a realy short moment the "plug-in-sound" sounds twice (connect and disconnect), also for a very short moment the phone shows the debugging-icon...
USB in general seems to work in the system; I can use USB-OTG as normal.
I'm a little bit under stress, because I will leave Germany in a few days for several months. And 1.) I will need a working phone 2.) I don't want to spend money on a new one (travelling is very expensive...) and 3.) I don't really have the time and the nerves to work days on these problem...
:crying::crying::crying::crying:
I'd say that you have lots of old drives on the computer. Take them all off. I pulled out my hair over this. I took dozens out from old phones and my Nexus then it loaded a driver and a message came on the phone asking to recognise the computer...
Thanks for the tip, but it didn't work for me.
I removed all former smartphones, massstorages etc with USBDeview but my problem is still the same.
I recognized that on my dad's computer even the Windows-dialog for media devices opens...but theres still only the same short appearing of the mass-storage and debugging-symbol. Klicking on the Windows-dialog ends in nothing...
Hello,
When connected to a PC, it is showing up as "QHSUSB_BULK". I only have official software from AT&T OTA, and phone is not rooted.
From my reading online, it means hard brick..... I cant get into recovery,download modes or anything at all now..... definitely not motherboard since the phone turned on over the weekend, when battery was almost zero and had to connect to charger to completely turn on.....
Tried downgrading to kitkat from lollipop because a continuous restarts.
Currently, neither fastboot nor ADB recognises this phone or I cant use LG flash tool to install official kitkat onto it. I have tried looking at various forums and couldnt find this exact situation of phone not turning on at all. Also phone is not showing up in disk partitions as well
Can someone tell me how to fix this phone, having this issue from almost 3 weeks now.
I got a same problem, In my case, I changed the battery then fixed the problem
ANy help guys...This G2 forum is too quite
Any help people.... Its been more than a month now
If you cannot get into DOWNLOAD or fastboot then you will have to open the device up and short out the 2 circuits. I just had the same thing happen to me when I ended up putting mismatched boot files on the system. It is time consuming and a pain but really not that hard. MAKE sure you have the right tools. I bought some off amazon before doing.
Dear XDA-community,
My Nexus 5 (D821 32GB) only charges while in bootloader mode.
Symptoms:
It spontaneously stopped charging in a normal way yesterday. By that I mean, that my Nexus 5 does not charge while switched on. While switched off, it loops the following way: it switches on, shows battery logo with the lightening, then goes to the logo that shows an empty battery (even though it isn`t empty, this logo usually shows loading progress, in my case it is not animated, meaning it just stays "empty"), after what the phone switches off and it goes back on again.
My temporary solution:
To circumvent that, I found out that it always charges while the bootloader screen is on (bootloader version: HHZ20h), and sometimes charges while in recovery mode (I have TWRP 3.0.3.0). So I used this method to load the battery.
My troubleshooting:
After extensive search on Google, the only reasonable thing that was said in one of the forums was that probably Android 6.0.1 detects some kind of danger to charging my battery and refuses to do it (I had the Xtrasmooth 6.0.1 custom rom with Xposed installed, stock kernel). Next thing I did was installing the app "Ampere" which told me that my phone`s battery, even though close to 3 years old, is in "good condition". Assuming that it is the OS that is messing with my charging issue, I completely wiped my phone, only leaving TWRP and an unlocked bootloader.
Please note:
I have tried all kinds of cables and chargers, even tried connecting to the PC to charge. My original charger works perfectly fine, and the charging port itself is clean. Like I said, the phone charges only while in bootloader. Battery life is also normal.
Question to you guys:
Here I am, with a fully wiped Nexus 5, ready to install a new custom ROM and being unsure what the issue might be.
Can anyone help me get my phone back to charging while the phone is on?
Is there a way to separately flash/work with usb connector drivers?
Thank you in advance :fingers-crossed:
Update 1:
Flashed latest factory image and returned phone to complete stock, problem persists. Why would the charging port not work while the phone is on?
Update 2:
Enabled USB debugging. Phone is not only not charging, but also cannot connect via USB to my computer as MTP (it is simply not recognized at all). In Windows Device Manager, it does not show up at all, even under "Other devices" (I uninstalled all possible drivers to see if it Windows 10 would react to it getting plugged in, it does not). I believe the problem is not the hardware of my phone (as it can charge and connect to the PC while in bootloader, fastboot commands work, could not manage to get the ADB commands to work in recovery), it must be some kind of internal driver issue.
Hi,
I have exactly the same issue. I have tryed all. I flash my Nexus 5 to Android 5 and the to 4.4.4 but nothing worked. Have you being able to fix the problem?
I also think this is not a hardware issue since I have changed the charging port and nothing happened and the same with the battery.

It could be a defective USB flex cable. There are 4 pins: 2 for charging, 2 for data transfer. It's possible for the phone to charge and not be recognized as a phone when connected to a computer.

5 pins...
Yes, there are 5 pins but I throught 2 were used for data, two for power. I admit I was wrong in this belief.
