[Q] Why is MTP inconsistent?

Let me preface this post with a few of the background details.
using Windows 7 (64 bit)
all drivers are properly installed
currently using BAMF Paradigm v1.2
the issue that I sometimes experience has to do with recently created or deleted files. Let's say I delete a file, using Root Explorer. If I then plug the phone into my computer (connected via MTP, Windows will still show the deleted file. But of course, I can't copy it or manipulate it in any way, because the file has already been deleted.
And sometimes the opposite happens. Let's say I back up all my user apps with Titanium Backup. While I know that the internal SD partition isn't wiped when wiping data to install a new rom, I still like to have my Titanium Backups copied off the phone and onto my computer, for further redundancy. What I often do is use Root Explorer to make a zip file from the entire Titanium Backup folder, to make it so that I only have to copy one zip file over to the computer. But if I plug the phone into the computer immediately after making this zip file, it won't show up up in Windows. But I know that the file is there. I can see it in Root Explorer, and I can even pull it off the phone using the Gnex root toolkit (http://forum.xda-developers.com/showthread.php?t=1400871).
If I wait a day or so, then the files shown in Windows "catches up" with what is and what isn't actually on the phone. In general, this is something that I'm used to now, and I can live with it, because I don't actually need to plug my phone into my computer very often.
My question is, why does it behave like this? I've seen this on 3 different computers (all Win 7 64 bit, and all with properly installed drivers), and across multiple ROMs. So I'm assuming that the issue is with the MTP transfer method?
Thanks in advance for any insight.

I've noticed something similar. Happened to me on:
CDMA 4.0.2 stock ROM, rooted & CWM installed
Windows 7 32-bit
All Drivers (FastBoot, ADB, etc) working properly
I noticed when I installed CWM, made a few backups I could see the folder and files using Root Explorer or any File Explorer (ES for instance) from the Market. Still wouldn't show when connected to the PC through MTP.
After a phone reboot, they appeared.

also happens on Galaxy Tab 7.7
only a reboot will fix it

[Q] cant copy files to the phone from pc

i have, on sprint, the galaxy s3, NOT the i900 or whatever that means. mine says model number SPH-L710
i have it rooted with the phantom rom installed, with superuser permissions. however, not sure what happened
but for some reason, i can no longer transfer files, any files, from my pc to the phone. this includes pictures,
music, documents--anything. the files are my personal files and music i ripped, and never had a problem
copying before, and all this just started. unless im hooking it up wrong, which i doubt--using the usb cable from
pc port to the phone directly. it does show the charge icon, and in the usb settings, usb debugging is checked
and also checked on media device (mtp). another option which isn't checked is camera (ptp), unchecked.
what happens when i try is, on the pc i get a box that pops up and says--do you
want to copy (file name), your device might not be able to play or view the file. i do have 2 options, to skip or copy
anyway. well when i click copy, it goes through the motions, but its not on the phone. no matter what file i try, a
pic, small wav file, etc....just will not copy and no
where one the phone is the file. another issue that seems to be going on is, the best way i can
explain it is--when the phone is hooked up to the pc, is it possible for whatever it is thats running to make the
phone able to receive copied files, go to sleep? because another error message i get when trying to copy is
it sits there for awhile, then eventually says "device not responding, disconnected" and on the phone itself its
on the main home screen like i wasn't doing nothing.
ive rebooted the phone several times, same results--nothing wil copy to the phone....
sooo, what am i missing?
update--- since that post, something else now happened. the phone flashed on, saying "sd card not mounted"
when it is. it is in the right way and all that, but when i go into settings/storage...at the very bottom it says
sd card, insert sd card
lol...so what the heck is that all about? the card is definatelly in there, and astro file manager shows some
files on the card but........

Well, it could be a couple of things.
First of all, make sure you have the Samsung USB drivers installed. It could be a corrupt driver, but probably not. It won't hurt to reinstall it, anyway, just to be sure. Here's link:
http://downloadcenter.samsung.com/c...nt_L710_GSIII_Samsung_USB_Driver_v1_4_6_0.exe
Make sure your phone is not locked when you're trying to transfer files. If you have a PIN or a PATTERN lock enabled and it locks, it will disable the MTP application from trasferring files.
Try reflashing the ROM as well. Maybe the MPT application got corrupted somehow?
As a last resort, you can restore your phone to stock unrooted status and see if that resolves the issue.

I had the same thing happen to me. I fixed the problem by going into device manager and clicking on to mtp and updating it..
Sent from my SPH-L710 using xda app-developers app

I had the same thing happen to my SdCard and now it is kinda dead... before yours gets damaged, remove it and insert in a PC with a sdcard reader. Run command prompt (Start>Run>cmd and enter) and do a scan disk or check disk by entering "chkdsk /x /f driverletter:" use the drive letter assigned to the sdcard then enter, let it do it's thing.
This will fix the file system and you shouldn't more problems with the sdcard not being read. As for the MTP, do as the other member said and try updating the MTP device in in device manager or uninstall the drivers and install directly from Samsung.

Problem copy files to int and ext SD

After 24 hours of search through the web I could not find a solution, many ideas but nothing seems to work, cause I can't find the exact reason:
What is the case? I try to copy a .zip to my device, the process starts and finishes after around 60%, I see the file on PC and device but the size does not fit (it is BIGGER!), md5 also. After a while the file vanishes completely and there is nothing......
R/W permissions should not be the prob, cause I can install apk, can delete files also and paste SMALL files unto the device (as it seems).
Someone with a little help, even without solution I would solve it by myself if I only knew, what's going on. THX :good:
Edit: Tried to connect with Kies3 and it started an update to latest firmware and Kies also failed to install something to storage

Update External storage
Well, internal works fine, but all files copied to ext sd still vanish after reboot and even after disconnecting usb from pc.

Not all files showing up in windows file explorer.

I am using windows 8.1 (tried on 2 different systems with same OS) and viperone rom 2.5.0 on my HTC one M8. (this is a problem i always had even on the stock rom, I thought that a custom rom might fix it but i was wrong).
When i connect my phone to my computer, it gets detected instantly.
It finds the internal sd card but also the external sd card.
HOWEVER, when i go to the internal sd card (So the memory the phone has by default) There is no Android folder. (you know, the one with the .com-facebook blabla files in it)
When i open a file explorer on my phone I can perfectly see all the files and folders on my Internal SD card. But when I use the pc to find these files, allot of them don't show up. Even some files in the ROOT of the sd card are not showing up, and these are simple .png and .log files. AS IF WINDOWS 8.1 DOES NOT DOESN'T RECOGNIZE THE FILES, and therefor decides to just not show them.
- YES i have turned on Show hidden files and folders -
Oh yeah, sometimes these folders do randomly pop up in there on the pc but then the are gone just as fast as they appeared. Also transfering files is very, very slow and gets interupted from time to time because windows "Cannot connect to device" or "Lost connection to device".
I keep wondering, why can't it be easy like an simple usb stick/drive. Those things are just plug 'n play. I recon that android should have this same option but it keeps disappointing me
I remember the good GingerBread days where you pressed the button on your phone CONNECT STORAGE TO PC. And it worked every single time, without delay or other crap. Just like CWM with its USB Storage function.

Look for a folder named "storage", in there you find the folder "emulated" and in there is the folder "0" open it and you'll see all the folders you have on your phone

SD cards are not reachable

Hello!
First I don't really have much experience about android. (I know it is not a good start)
About a month ago I bought a note 8.0. I also bought a 64 GB SD card. I would have liked to use the SD card with root access for all applications.
So I rooted the device and I installed and ran SD KitKat fixer. It was not success. I found this article: winaero.com/blog/unlock-external-sd-card-writing-for-all-apps-in-android-4-4-kitkat I did the steps but I couldn't modify /system/etc/permissions/platform.xml not even with file explorer (with root permission). I could save the file but the file didn't changed. After that I made a mistake. I copied the file to the other partition. I changed the file and copied back to the original location. (I left an oroginal copy on the SD card but it could not be reachable after the change) After this the device could not read or write any of the sd card partition except the system partition. I connected the tablet to my PC, I see the SD cards, I can open them, but they are empty and I can't write them. In the system setting (on the tablet) the SD cards are visible.
1. I tried to modify back the XML file but I can't open it with file explorer.
2. I reset the the tablet. It didn't work.
3. I tried to connect the device to Samsung kies. I wanted to make fore reinstall but kies couldn't build the connection.
Error message:
Failed to connect device.
Connection or use may be restricted if the device access (including writing)
is prohibited by your computer's security program, or for any other reason.
4. Keyboard is not working I connected one with USB. I can connect to my wifi network. I tried to connect to google play. It accpeted my login datas but it couldn't connect to google servers.
Because I can't write the drives of the tablet from my PC, I can't copy a rom to the device.
File explorer is not working on the device. It can be opened but nothing can be seen.
I think I can't take back the tablet where I bought it beacuse I lost the warranty with the rooting.
Can anybody give me advice what should I do?
Could somebody please make available the original platform.xml for me?
