[Q] Unrooted S3 not recognized by Mac/Android File Transfer app

I tried going into "Media Device (MTP)" and then tried "Camera (PTP)". Neither seemed to work. Any ideas?
Specs: Mac OS X 10.7.4, 2008 pre-unibody Macbook Pro, unrooted T-mobile Galaxy S3 (white)

I tried for like 30 minutes to get my phone to work with a mac. Ended up using Airdroid and just transferring files over wifi.

I personally use wifi file transfer.

Thanks, Airdroid looks great. But for transferring large files, wi-fi is pretty painful. Just for the sake of brutal comparison, I found I was getting less than 1/10 the transfer speed (on video files 300-500mb) over wi-fi. Guess I'll have to get windows running on my mac again...unless there's a way to actually do file transfer over usb on my Mac..? (without cracking open my phone and removing the msd card)

I've run into the same issue myself. The phone is recognized, but nothing ever happens as far as the drives popping up.
Best workaround is to just use parallels if you have access to it...

Another option is to pull the SD card and plug that into your Mac. Luckily I have a PC as well so I don't have to come up with a workaround.

Info on the Marshmallow update for Turbo 2

I had a little chat with "ASHLEY" from Verizon's Live Chat. Apparently (and she told me this after i factory reset my phone) the marshmallow update is getting little patches so that everyone's phone is prepared... a little annoying since i almost got to installing but i had to take my phone off Wi-Fi for 6 1/2 hours while i was at school, and so the update i would've gotten was canceled by verizon or something... I even had downloaded part of it.
Just a little FYI.

Thank you for the update. I just picked up the phone. I deferred the update when I set up the phone and now I can't get the download back. Now, I most likely know why. I'll wait a day or two. If I can't get the update back, I'll hard reset the phone. Sighs...

Verizon's Twitter support just confirmed a hold on the marshmallow update. Any exact date then?

I had the OTA update notification on Friday but no wi-fi at work. Got home and the download failed and then got software up to date when checking on the phone. Plugged the phone into my pc Saturday night and the Verizon Wireless Software Update popped up saying an update was available. In less than 20 minutes I was good to go.

Except my device NEVER wants to pop-up on the software upgrade assistant, and it's on MTP mode. Any help with that? I'm on Windows 10 too.

Some have reported the the Verizon software update assistant works if you connect your phone to your pc/laptop via USB 2.0 -- but not USB 3.0. That didn't make a difference for me. We've got 3 Turbo 2's: two of them got both updates successfully OTA. One of them never got it OTA, and still gets nothing when we check for updates. I've tried connecting that third DT2 to my laptop and using the software update assistant - with the phone connected at different times to each of the 4 USB ports on my laptop (3 of them are USB 3.0, 1 is USB 2.0), and I've toggled MTP mode on and off, but no joy: the update assistant never recognizes the phone. However the laptop does, indeed, recognize the phone, and lets me open a file browser window and look at files on the SD card.
Only variable I'm not confident about here: when I connect the phone to the laptop, there's the typical Windows popup that asks what I want to do when this device (the phone) is connected to the laptop. Note: the update assistant is NOT offered: just typical options such as, "transfer media files to PC". Not sure which to accept, I've ignored that prompt -- wondering if perhaps I need to select one of these options in order to complete the MTP connection properly?

None of my USB ports work. I've tried uninstalling and reinstalling everything, with no results. Unless there is a manual solution available, I guess I'll have to wait through this 2nd straight Verizon branded false alarm.

You can run it and check for updates manually once it's installed. Just to be clear, when my phone is connected to my pc if I pull down the notification menu on my phone and tap the usb notification there is an option to install software that, when checked, adds a cd installer in windows explorer on the pc to install the Software Update and Repair assistant. @jonstrong I just ignore the pc popup or select take no action.

I had similar issues, I installed SUA on my laptop and it would not detect the phone. Installed it on my desktop and it recognized the phone. Both are running Windows 10.

What cords are you using to connect? Sometimes that can make a difference.

Doesn't matter what cord I have, won't detect. I'm screwed at this rate.

I can not get the Software Upgrade Assistance (SUA) to work on my Desktop PC but was able to get it to work on my wife's Desktop PC. I tried on my laptop and found that the Verizon Software Upgrade Assistance (SUA) works (recognizes the phone) on the laptop's USB2 ports but will not work on the USB3 ports. My wife's PC has USB2 ports and My PC has USB3 ports. All the above computers are running Windows 10.
Based on my testing, it appears that the Verizon Software Upgrade Assistance (SUA) does not work with USB3 ports.
Try using a PC or laptop with USB2 ports.

Won't even recognize on USB2. Repeating: Screwed

make sure that your phone does not have USB debugging on. Also make sure you are using OEM cable (from any brand really). COnnect to a USB 2 por and go to www.motorola.com/verizonsoftwareupdatewin (if you have a windows computer) or replace win with mac
Download, install, and run software assistant... unplug your droid turbo 2 a couple of times until the software sees it... then it should work

1. my signature is old... lol
2. don't let your phone lock/ go to sleep while it is downloading

For anyone who's still having trouble getting the update on their Droid Turbo 2 - my experience might be worthwhile knowing about:
We've got three DT2's (would have been four, but my son opted for an iPhone). The first two were offered the update when the first big wave came around - before they shut it down a second time; we accepted the 2 step update for those two phones, and they were both successfully updated to Marshmallow over a week ago. The third DT2 however never got the offer, and punching "check for updates" never found the update either -- even as recently as today, March 19.
I had tried connecting the third phone to my laptop via USB -- and made sure to use the USB 2.0 port on my laptop (the other three USB ports are USB 3.0), and made sure the phone was set to MTP mode. Still no joy. Never offered the "CD Install" option on the phone, even though I had checked both MTP mode and Software install on the phone under USB options.
Finally this evening I tried the same on a different laptop, and tried a different USB cable as well. This time, the phone actually offered the CD install option, and was able to prompt the laptop to download and install the Verizon Software Upgrade Assistant (VSUA). It was till touch and go for a while: once I fired up the assistant, it still didn't seem to recognize the phone the first several times I tried it. Finally -- I let it sit for a couple of minutes with the VSAU loaded and the phone plugged into the laptop, and this time the phone showed up in the Upgrade window. I selected it and clicked on the upgrade button. I was amazed at how long the download took, as I remembered the "1 of 2" upgrade being pretty small -- with the 2 of 2 being the 1.1GB file.
Finally - the download completed, and the update began. That also took a long time, but I could see the progress indication, so I was encouraged. In the end, this single upgrade completed, and then the Android "upgrading" process began for what I recall to be 40 programs (probably what my daughter had installed on her phone) -- again -- I was surprised at how slow this was, but I made a point of NOT disturbing it.
Anyway - it finished, rebooted, and after this SINGLE update, the phone was all the up to the latest update for 6.0 for the DT2 -- the same version I'm at after doing the 1 of 2 and 2 of 2 updates the week before last -- 24.24.11 kinzie_verizon.verizon.en.US . It seems that the VSUA got my daughter's phone there with a single update -- something that surprised me. Maybe there's a new update file out there that does this in a single pass? Don't know.
But -- the take away for anyone still frustrated by not getting the update yet should be: you probably CAN get it, if you're patient enough, and are willing to try a couple of different cables, and possibly different PC's (one of my laptops couldn't deliver the update, but another was somehow able). Seems that it's still on their servers waiting to be downloaded, and VSUA can actually function if you somehow get the magical combo of computer, USB 2.0 port, proper cable, and LOTS of patience and willingness to try something repeatedly.

Well I Finally managed to get the VWSUA going on an older computer. Upgrade in progress...

Upgrade complete. I'm now on Marshmallow. Thank you all.

USB 3.0 File Transfers hang.

I picked up this cable to support high speed file transfers with my new Pixel C: http://www.amazon.com/iOrange-E-Bra...01ABXMQLQ/ref=cm_cr_arp_d_product_top?ie=UTF8
Plugged the A end it into a USB 3.0 port on my computer and the C end into the Pixel C, then attempted to copy over a folder with a little over 2 Gig of files.
It immediately Hung while transfering the first file. I canceled, and tried to simply open one of the directories on the tablet from my windows file explorer and it took forever just to open an empty folder. Unplugged the cable, and plugged it back in to another port and tried again. This time I got almost half way through the 2 Gig directory transfer when it hung again. Tried another four or five times, and never got past the first dozen files or so.
Unfortunately, my PC and the Pixel C are the only two devices I own which support USB 3.0, so I'm really not sure which is the problem. Anyone else have any luck doing large file transfers to the Pixel C over USB 3.0?

I know this is an old thread, but has anyone else come across the problem or found a fix? I'm having this problem with my Pixel XL at this very moment. Very annoying!

Computers don't recognize XL2 to transfer files

I've tried multiple cables, multiple computers, multiple USB ports with no luck. With my original XL, it pops up file explorer and I have to swipe down from phone to select transfer files and can access them. Works with all the same cables, ports and computers I tried with the XL2.
I've also tried to use the included USB-C to USB-C to transfer between XL and XL2. I get the notification on my XL that it's connected to my XL2 and can access the XL2 files, but I can't access my XL files from my XL2. Doesn't even show it's connected. Tried all the pull down options on both phones with no luck.
What am I doing wrong? This should be the easiest thing to do and had been on every phone, but not this one. Please help!

Did you set the connection type to data transfer?

I had the same issue and with a little searching I figured it out.. Make sure the phone is set to "Transfer Files" in the notification window drop down and download the Google USB drivers zip and install the driver after unzip. Right click the driver file and select install.
Since this is a new account XDA won't let me link yet so Google search for : Get Google USB Drivers

I'm having a similar issue, and we're not alone. I'll copy what I posted on reddit.
Asus ROG Maximus Hero IX motherboard. Tried with multiple cables. Wifes OG Pixel detects it is plugged in right away, my 2XL has to be screen off and set down for a couple of minutes, then the phone recognizes it is plugged in and starts charging and is available for data transfer.
Seven minutes and twenty seconds before it started charging, and another twenty seconds before the computer recognized it as being attached and ready for data transfer. I'm going to do it a few more times to see if there is a pattern.
Edit: Second time was seven minutes for both, third was three fifty one for both, eleven thirty three on the fourth.

I'm not having this problem at all. Once file transfer is enabled on the Pixel I get a popup in Windows asking how to handle the connection to the Pixel 2 XL.
I is a different story with my Nexus 6P -- I can do adb commands but the Windows does not attempt to access the storage on the device.
-- update on Nexus 6P: if I toggle the setting to PTP mode the Nexus shows up in Windows Explorer. Then when I toggle back to MTP I can see the storage.

Using Windows seems to be the common problem when connecting Android Phones to a PC.

I don't get any connection option when I connect my XL2. It's like it's not even connected. My XL works perfectly fine with same cords and computers which throws me for a loop.
I'll give the shot about changing to other options and back to file transfer and see what happens.
I may need to wipe the phone and start over or maybe it's see sort of bug. Just kinda sucks, just need to make sure I can access the phone and one of the main reasons I got the 128gb version

I have encountered similar issues when using Windows, but my laptop dual boots between Windows/Fedora Linux. I only boot to Windows when I have to. Linux has no issues communicating to Android Phones. Maybe find a Linux Bootable DVD and give it a spin

When you look in the Windows device manager do you see an entry for LeMobile Android Device? This caused a problem for me in the past. See this post for a possible solution: https://www.reddit.com/r/Nexus6P/comments/5nc64z/adb_drivers_showing_up_as_lemobile_android_device/
A shortcut to the steps in the article is to simply expand the LeMobile Android Device node, right-mouse click on the Android Composite ADB Interface, click Change settings at the bottom of the General tab, go to the Driver tab, click Update Driver; Select Browse my computer for driver software; browse to the directory where Android Studio (or adb tools downloaded from https://developers.google.com/android/ota) files are located; make sure Include subfolders is check) and replace the LeMobile Android Device driver with the Google driver.
(If you have to do this, more than likely you will have to do it each time you reboot.)

I don't know if this will have any effect but on the pc, plug to the usb ports on the back that are direct to the motherboard instead of usb headers on the top/front of pc.
I have this issue with a TomTom satnav and a Mio miview dash cam. Unless they are plugged in on back pc / with Windows 10 doesn't recognize

That sounds easy enough, but it's dumb (to me anyways) I should even have to do this to get the computer to recognize my phone when it'll recognize my original XL and of course wife's S7. My phone gets plugged to the computer almost every day to copy files off of, at worst every other day.

I went to the device manager on 2 computers and surprisingly nothing showed up. It's like I'm not even plugging it in, while as soon as I plug in my original XL it pops right up. When I attempt to plug it in, it doesn't even attempt to install any drivers like it sometimes use to. I'm going to install the ADB tools when I get home today and see if that helps any to recognize it.
Just tried it on my work computer which does have ADB on it with no luck or anything in device manager
I literally went through all my USB-C cables I could find yesterday, probably 12-15 at least, and I DID manage to find one that worked..... a 6" cable, lol. I can't figure out why this one works and others don't, very more odd is it's the same brand as other longer cables that don't work. Not sure what to make of it, other than voltage loss with the longer ones....just enough to make it not work.
I do have a 2nd XL2 that should be due in this week, was suppose to ship on 22nd. I was going to return it, but now I'll have to take it out of the box and at least test if it works with the computer. I'll report back.
Open to any other suggestions if anyone has any. Thanks again for the replies!

Nothing at all, it's like it's not even connected. Just kind of dumbfounded on why when my XL never has had an issue. Attached a screenshot. The one with the triangle doesn't have anything to do with the phone though, it's always been like that and never bothered to mess with it.
The 2nd XL2 shipped yesterday and due in Thursday, so will be curious on if it has an issue. Hopefully it works as intended and I can just set it up and send this one back. Fingers are crossed for sure.

Are you updated to the latest ADB drivers? Right down to, you might have to remove and reinstall. I'm pretty sure I read that it's required.
"Good judgment comes from experience, and a lot of that comes from bad judgment." - Will Rogers

If the Pixel 2 is plugged in your screenshot indicates that it is present on the USB bus. It's like the drivers aren't completely loaded.

I haven't seen it mentioned if you have turned on USB debugging in your phone's Developer options. I'm pretty sure that is required for the computer to see it.

I had it enabled for a while, but no such luck. I'll give it another shot, haven't had it on while at work. Also will uninstall and reinstall ADB as well.

When this has happened to me a few times, reinstalling the Windows MTP drivers has worked. Someone else posted these instructions that worked for me.
1. Go to C:\Windows\INF
2. Find the file "wpdmtp.inf"
3. Right click the file and click 'Install'
4. Once that is done, simply plug your phone and it should work.

Pixel 2 XL doesn't mount on computer any more.

I was hoping the December security patch would fix it but nope... Nothing
Any ideas?
Running Windy 10 pro. I've connected it to my laptop and my desktop same problem.

Do you still have the dongle that came with your pixel? If you use it to connect it to a USB flash drive, wait for it to show that it's connected, then plug your phone into the pc and it should work.
Worked for me twice.

most likely the pixel driver is acting funky. I imagine if you were to uninstall (the driver) and have it install again, it would be right as rain... Once you get to the Device Manager, it should be straightforward and easy.
I'm hoping you know how to do all of this already and can save me a step-by-step guide, but I'm very willing to if you need.....

I had this problem yesterday...
tried two pc with windows, one linux, three cables ... still error.
solution was dust in usb-c port. Clean it and phone can connect to pc again.
