MSC Massstorage Mode doesn't work? - Xperia Z3 Q&A, Help & Troubleshooting

Hey,
I got the Problem that MSC mode for USB options doesn't work for me. It shows a blank icon in Windows and tells to insert drive.
I'm using a 128GB SanDisk microsd card if that could be the fault..
Thanks in advance for any help

Still having the Problem and it's rather annoying

Today i reflashed from LinOS15 back to 6.0.1 and on first connect, Windows installed driver and showed the device correctly n Mass Storage Mode.
Now after restoring apps etc. it again shows a blank sdcard in Windows explorer. Does really nobody know what could cause this or how to fix this ?

So i figured out it's the priv-app "enhancedusbux" which broke USB MSC (Mass storage Mode).
After restoring, USB Mass Storage mode is working again.
Maybe it helps someone

Reg Issue?

Hi guys,
I have a T-Mobile Ameo 16Gb but im unable to see the internal storage on the device. All i have in the memory options are Storage Card. Not the internal storage.
Anyone got any ideas?
Presumably you don't have it connected to the PC in 'disk drive ' mode do you?
If that's the case then the drive is demounted from the mobile OS.
Have you tried a soft reet? It may also be worth going Start/settings/connections and tapping USB to PC and making sure Activesync is selected.
If none of that works then I'd try a hard reset and if that doesn't work the device is probably faulty .
Or... somebody has uploaded a rom from X7500/X7501, which does not have drivers for 16Gb Flash Drive.

Hellfire 2.1 USB Mass Storage Faulty?

I'm new to Android custom roms and just flashed my G2x to Hellfire 2.1. Everything went pretty smoothly as I have relatively strong tech knowledge and followed all the guidelines carefully. The phone is now running a lot faster and everything looks great, with the exception of USB storage. After extensive searches I can't seem to find the solution to the problem.
The phone doesn't have an external SD card and I store everything on the internal SD. Under CM settings I have set the phone to use the internal SD. Latest LG G2x USB driver has been installed on Windows.
Now by default, USB debugging on the phone is ON. When I plug in the USB cable, the "Turn on USB storage" screen doesn't show up on phone and no SD drive is detected windows. When I turn USB debugging off, the "Turn on USB storage" screen comes up, and after clicking "On", Windows correctly detects the drive.
But after the phone reboots (USB debugging is now off since I set it off before reboot), the USB stops working again. This time the "Turn on USB storage" screen does show up on the phone, but after clicking it to turn on, Windows does not detect any drive. Basically nothing happens. However, the strange thing is if I go to turn the USB debugging back on, phone again prompts to turn on USB storage, and this time if I turn it on, Windows detects the drive. Then I turn off the debugging again, and it still works fine (screen comes up and Windows can detect).
So basically it works until the next reboot. No matter how the debugging option is set, the USB simply won't work right away. (If it's set to off, the problem described in the previous paragraph applies. If it's set to on, the phone simply won't show the "Turn on USB Storage" screen as stated initially in the post.
I have gone back and force and tweaked various settings all with the same result. I have also made sure to test this on different computers with fresh installed G2x drivers and they all exhibit the same problem.
Your help will be appreciated.
Assuming you flashed it correctly using nulifier to wipe and than flashed I would reboot to recovery go to advanced and fix permissions... Reboot turn debugging on and check use internal storage. The reboot again and than see if that fixes it for you.. I have 2.1 flashed and when I mount both sd's mount internal and external so it should be working for you if not you might have a corrupted download and would have to redownload and flash again

Do you mean you have both internal and external SD, and when you plugin the USB cable (I assume you have USB debugging on), both cards mount to the OS as two drives? Could you please do me a favor by taking out the external SD, and see if the internal SD would still mount correctly?
And btw are you mounting under Windows or Linux?
Thanks a lot.

Didnt work for me
DJLamontagneIII:
I finally got an external SD in. I reflashed, left USB debugging on. When I plugin the USB cable, the phone's "Turn On USB Storage" screen doesn't come up, but I noticed that in the pull down's notification/running it's there, below the "USB debugging turned on" ,so if I click that, the "Turn On USB" screen shows up, and after clicking to turn on, both drives mount on Windows.
Is this how your phone behaves too? If yours actually have the "Turn On USB Storage" screen pop up on front (just like the stock ROM does), what do you think is causing mine to behave in this way?
Thanks again.

[Q] Internal SD Card as Mass Storage Device Problems

I'm having a problem connecting my device to a computer as Mass Storage. It was working fine for a while until it got unintentionally unplugged while I was connected via ADB as root. The device will connect fine as a Media Device (MTP), but when Mass Storage is selected the drive letter comes up but is greyed out (how it looks when you have a corrupted usb drive). Prior to the problem you would get the internal sdcard partition. I'm also having a problem with Samba Fileshareing bombing out temporarily before enabling wifi sharing, but if I click "wait" on error screen Samba finally starts sharing. None of this behavior was present while the mass storage was connecting properly.
I have no external SD Card installed, I'm rooted, I've applied the 6MB OTA update and have all the latest moto drivers on my computer.
I tried fixing this problem by first doing a factory reset (no luck) then I fastbooted back to the stock image and reapplied everything. None of that fixed the issue.
I think the device is having a hard time unmounting the internal sd card partition? I'm not sure what's going on and I've searched to the end of Google. Any help would be hugely appreciated.

[Q] usb problem?

Hi,
When I connect my phone in usb mode I see my SD card on my computer but not the phone's internal storage (latest HiSuite is installed). The MTP mode does not show all my folders and files that's why I really need to see the phone in mass storage mode.
Also, whenever I connect my phone to the computer, USB debugging mode turns on even though I disable dev mode. I tried factory reset twice and install/uninstall HiSuite but it still does not work.
That would be awesome to have some help.
Thanks
Can you guys at least let me know if you are able to connect your phone's internal memory in mass storage mode?

MTP mode should display all folders/files in internal memory. However, same as you, sometimes, the computer does not show all. What i do is just disconnect, then reconnect. Oftentimes, it solves the problem. If not, then i both restart the computer and the phone, then it will be ok.

S2 plus(GT-I91059) cyclic redundancy error in mass storage mode

So i just flashed android 5.1.1 on my galaxy s2 plus and everything was running smoothly until yesterday I started getting cyclic redundancy error in my mass storage mode (which was working fine since update until yesterday). I can however copy files from PC to sd or internal storage using MTP mode. I can even copy files within phone on both sd and internal storage. However whenever I switch to mass storage mode (Use a app USB mass storage enabler Also tried without using app from options) it shows the sd card but gives me cyclic redundancy error while copying and card is not seen on the device as soon as i unplug the cable(is original if u will suggest that) it is seen again. I aslo ran chkdsk but card shows no error.
I encountered the same problem a day before and after copying a few files in mtp mode the mass storage mode statred working again but not this time. Please help
