[Solved] USB OTG external storage is not writeable - Xperia Z3 Compact Q&A, Help & Troubleshooting

When i try to copy files to my USB external storgae, the app tells me that i need to give it permission. i selected the USB storage but it fails, and Total commander says wrong location, even i choosed it correctly. When i press cancel, it ask me to re-mount as read/write as root and it works. Only Total Commander can do that, but it keep asking for permission.
My device is running Lollipop 5.1.1 with latest SuperSU
do you mind checking my platform.xml in attachment that was located in /system/etc/permission/ ?
EDIT: because the annoying lock thing was turned on, on SDcard adapter again. oh my god...

Internal Storage2 ????

I connected my diamond via USB to the computer, I set it to use as a drive. There was a rush and I had to disconnect the USB cable without first stopping it. Now the directory "Internal Storage" has only backup files, and there's another directory called "Internal Storage2" which has the data originally in "Internal Storage". How do I fix this?
Thanks
Check to make sure the files under Internal Storage aren't important, then delete it and soft reset. Should fix it, I think.
thanks for the reply, but when i try to delete it give an error saying sharing violation. any thoughts?
thanks
nvm it works, I renamed "Internal Storage" to something else, then softreset. it didn't let me delete b/c of files used for IE.

[Q] MTP access of the SDcard (extern)

Hi
Would like to know if, when you try to access your data stored on the external SD via MTP, you can see all of your files ?
(Using Windows)
This MTP thing is a real mess for me, I can never have the full access to my files. With the Razr i I only have 2 folders with some media files when I open the device with Windows explorer... there should be a plenty of folders and I don't know why I don't see them and how I can see them!
Tks
PS: even with the internat storage I don't have full access. for example, if I create a zip file with some file explorer on the phone, it never show on the MTP device!
Give me back UMS !
That's normal, MTP is a very special mode, so you can't modify files or see some files..
But I don't understand why there isn't an usb mass storage when the phone is connect ?

I would love to have the answer
@ this time: no UMS on the Razr i ...
Then use PTP, it maps /sdcard and /external1 to your computer, you can clearly access them via a normal file manager.
PTP is worst ... it's made only for pictures!
There is no USB Massstorage from 4.0 upwards cause google decided to remove this feature....
ptp is made for pictures but it also can be used for normal files but mtp is prefered....
i am on ubuntu and after a nice little tutorial i am mounting my phone via mtp and i can modify and see everything, its mounted as usb would...
havent tried to see the external card because its ext4 formatted and running arch linux so

I know Google decided to remove ums on the stock Android. But it's not on obligation and constructor have all right to put it if they want.
BTW, I saw same screenshot of a razr vd or a razr maxx which has ums!
I'm running Windows and use Total Commander. There is a great plugin "totalanddroid" that gives me access to all my files (SDcard and internal memory). It uses adb and runs with USB connection or Wifi connection. I tried to find some adb explorer that runs without Total Commander, but none of them is really working on my machine. But maybe you'll have a bit more luck (my phone is not yet rooted, sometimes this seems to be a prerequisite).
NICE

MTP file delete from SD does NOT create free space

Hello folks.
I've been deleting files form SD card, using MTP. Deletion works without error, files are not shown any more.
However: The SD-card does not show any more free space as before the deletion.
Any suggestions?
Device Moto G 2. gen
stock rom 6.0
Hello folks.
I'm wondering if my question is not clear.
I have 30MB left on my SD, even though I did delete a bunch of stuff.
I really could use a hint - would like to copy some new content to it, once I get more "free" space...
Well, how have things turned out?
You know about the extra restrictions regarding external storage added in Android 6. You can barely use the SD card as it is, let alone have Windows do things to it.
Have you tried checking the storage with a file manager? ES File Explorer and X-plore could be granted some sort of write permission - see if the files are still there and delete them through your phone - although those two have a recycle bin option, make sure you uncheck it first.
And start using Temasek's custom ROM in the first place. If you're using the SD card as much as I do, that's the only reasonable option when it comes to Android 6.

Cannot find zip file in Storage/MicroSD (TWRP)?

Not sure if this has already been posted, so please forgive me.
I'm nearing the final step of rooting my P10: flashing the root file. I'm using SuperSU root, I downloaded the file on windows, then dragged it into the internal storage via USB cable. Booted into TWRP, but could not find the zip file in internal storage, nor can I find it in the MicroSD, because the folders in my MicroSD are all encrypted. SDcard in fact shows 0mb, hence after researching, i try to mount Micro sdcard, but i am unable to check the box in the mount section...
Yes I am using the latest versions of the root and TWRP. I've also disabled the lock screen password. First time rooter, I have no idea how to carry on, and am very frustrated, am I suppose to like format my sdcard? Please help, any solutions/alternative root methods would be greatly appreciated, thank you!
Edit: Realised I actually don't have my sdcard attached in my phone, so i guess the sdcard 0mb is called for. Still can't find the file in internal storage though.

Problem with using a thumb drive as expanded memory

I've had a Chromecast with Google TV for about a week. I added a usb stick for added memory . I'm in developer mode and have unknown sources on. Using the X-plore file manager, I sideloaded games with obb files onto the drive with no problem. However, a few days later, the Chromecast got laggy (unrelated I hope) and I had to do a factory reset. Since then, X-plore will not show the USB drive if I'm using the USB stick as device storage. I'm pretty sure that was the way I had the stick formatted before. When the stick is formatted for external storage, I can't transfer data to it. When it's formatted as device storage, it's not recognized on the file manager. Also, the file manager won't allow for an obb folder. I get a msg saying it's not allowed.
How did I screw this up? Please help :fingers-crossed:
Thanks from a confused noob
is it fat32?

Yup.
I think I figured it out last night. After I factory rebooted it, I didn't change some of the storage permissions on the apps .
Can't seem to get passed read only error with x-plore. Do I need to format to fat32 and how. PC is old and only gives me option for exfat and ntsf. Thanks in advance
