Android File Transfer on Mac not working correctly-- any ideas? - LG G6 Questions and Answers

Here's the situation. LG G6 us997, oem unlocked but not rooted. USB debugging is enabled and File Transfer (MTP) is the selected mode.
When I connect via USB to my MacBook pro (running osx 10.12), I am able to use adb to connect to my phone (push/pull files, etc). I am also able to connect to LG Bridge to initiate wifi file transfer (i.e. it recognizes my phone via USB).
However, when I open Android File Transfer it gives me a No Device Found error. If I switch the USB mode on the phone to "charging" and open AFT, I am given an error that suggests it sees the phone but knows it's not in File Transfer mode. It tells me to switch to MTP and reconnect, but then I again get the No Device Found error.
Here's the really strange thing. I performed two experiments. First, I plugged my G6 into another Mac (a mini) that had Android File Transfer installed, and instantly the file explorer popped up, working perfectly. That suggests to me that my cable isn't bad, and that my phone settings are probably okay.
But then I plugged my friend's Samsung Galaxy S6 into MY computer, and Android File Transfer popped open as it should, working perfectly. I'm not sure what this suggests. The weird thing about THAT is that plugging that same S6 into the afformentioned Mac Mini does NOT work!
So I'm stumped. I can always push/pull files via adb, but sometimes I want the simplicity of a drag and drop GUI, you know? A little more info: I think LG Bridge and AFT (and LG pc suite which doesn't work) can conflict, so I've definitely uninstalled those applications to minimize variables, rebooting between tests. I've also rebooted my phone between changes, and locked and unlocked it, and toggled File Tansfer to Charging modes repeatedly, and plugged and unplugged the cable, tried different usb ports, and switched cables.
Any ideas?

can't connect to pc...usb device not recognized

hey guys.
i've been using the xoom for about 3 weeks now. i have the latest motohelper driver. i'm using windows 7 x64. i've been able to access and transfer files before no problem. I rooted over a week ago and also have had no problems moving files around. accessing the sd card from the pc has also worked.
now yesterday I send my wife to move a file over, and she tells me it's not working. sure enough, no matter which usb port on the pc I plug it into, or how i disconnect and reconnect the cable on the xoom, windows gives me the USB device not recognized message.
I've tried rebooting both the PC and the Xoom. i've reinstalled the drivers. i've enabled and disabled usb debugging on the xoom. still get the same message. under device manager it shows as Unknown Device. if I go and manually select the Motorola MTP drivers it tells me it can't start the device.
we haven't done any recent software changes on the PC or the Xoom. specially not within the last two days for it to go from plugging in just fine to USB Device Not Recognized.
any suggestions?
thanks.

ADB not working

Hi guys...
Yesterday my new PH-1 arrived and today I wanted to use ADB with the app "custom navigation bar". My problem is: i can`t get it to work... I´ve used adb several times with different phones, but with the PH-1 it can´t connect with my Windows 10 computer. Is it possible that I can´t get it to work because Ì´m using a different USB-C cable (took 3 different from Xiaomi another manufacturer)?
How do get it to work? Everytime I connect the phone with the computer, I get the message USB debugging is on and I use MTP to work, but the phone doesn`t show the RSA key fingerprint. Any suggestions?

Mines wouldn't connect using the usbc cable it came with I had to use a regular usb to usbc cable for it to work
See your device manager. To see if you are seeing "Mata". You have to download the google usb driver and update it from there
I have S8 from my previous computer but i need to re install the driver again

You can also try this tuturial hope that it is working for you.
Try this > Download and install the essential usb driver > go to device manager and update the driver. Choose the option where you can change the source and select the driver in the list > go to the Essential Folder in Program Files and choose the file named "essentialadb.inf" for your pc. That should work
It's and old thread but if there is someone new to this...
My essential wouldnt work with the previous ADB i had installed that had worked fine with all my other devices.
I installed https://forum.xda-developers.com/showthread.php?t=2317790 and worked just fine. Make sure your device isnt connected as anything other than charging. The previous ADB i was using didnt acknowledge my device but on first try with Minimal i was prompted on my phone right away
I had the same problem when attempting to flash my ph-1, when trying to use the cable that came with the device. I used a standard USB-A to USB-C cable and everything worked just fine. I noticed on the 8.1 update notes for side loading that the team indicates that the cable that comes with the phone is "Primarily" designed for charging and not data transfer. So I'm guessing that it is of lower quality and doesn't handle the transfer speeds.

Hold either volume button while connecting cable from phone to pc, it will detect automatically. It may work.

Android File Transfer not working since VNS-L31C16B125 upgrade (Mac)

I'm running VNS-L31C16B125, EMUI 4.1.3, Android 6 and trying to connect to my Mac (10.11.6)
Since the latest Huawei firmware upgrade (which I installed last week) the Android File Transfer dialog is not opening when I connect my phone to my Mac via USB. The phone charges when connected to the Mac by USB, but the transfer options do not open on connection and the Mac tells me no phone is plugged in. I had no issues previously.
Things I've tried:
- Changed the USB cable (using the one that came with my phone) - no luck
- Checked 2x different cables with another Android phone - both worked 100% with the other phone (Samsung)
- Tried different USB ports - both work fine with the other phone I'm testing, but not with my Huawei
- After updating my phone I noticed that Dev Mode was disabled - I reactivated Dev Mode by tapping the build number, turned on USB debugging, selected USB config and selected MTP, restarted phone and computer - no luck
I can't find any other options or suggestions online. Hoping you guys can help.

File transfer not working on custom ROM?

When using the stock OOS, I can connect my phone to my computer and the file transfer works just fine. My phone shows up on my computer as normal. However, whenever I'm using a custom ROM (so far all of them have had this problem), file transfer does not work because I can't get my computer to recognize the phone. Debugging is on, and the configuration is also set for file transfer. Oddly enough I can get my computer to recognize the phone if it's in PTP mode, but it immediately dissapears when I select file transfer. I haven't had any luck finding a fix for this.

LG K20 Plus struggling with USB file access, and with Bluetooth casting.

I have two issues with my MetroPCS LG K20 Plus and my Windows 10 computer.
The phone has debugging mode enabled, but is not rooted.
(1) I cannot see any Android files on Windows File Explorer via USB. The device shows up, but no folders. I also do not seem able to use any Android-to/from-PC apps that communicate across the USB cable.
(2) I am struggling to find a portable way to cast my phone screens to a Windows 10 PC. I have tried Bluetooth, but the related Android Settings options appear to be missing. I can pair to the PC successfully. The PC shows the Bluetooth connection as "Connected", but the phone shows "Connecting" for a while, and is then unconnected.
Can you suggest ways to enable this functionality?
I cannot install PC software to do it because I might be in an environment where I do not have access to the WiFi network, or am unable to install software or browser extensions or drivers on the PC. I cannot use WiFi for file access for the same reason. Cloud access from a public PC is a security risk.
It seems that LG (or perhaps MetroPCS) is deliberately trying to thwart casting and USB file access, and I cannot think of why they would do that.
I also have an issue with connecting this phone through usb. Windows 10. Says device can not be reconized. May have wrong lg usb driver version not sure. Needd it to read so that i can unlock the bootloader.
