[Q] MTP not working after installing CM 10.1.3 (i9305) - Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help &

After going through a ton of hoops to get this thing rooted, then ****ing flashed, I (naturally) run into another infuriating issue that is USB drivers don't seem to work, I hear the USB connected sound on windows when I plug it in but nothing appears, connecting as a Camera (PTP) seems to "work" but I can only see some(?) of my files and nothing can be copied to the phone. I have no SD Card, only the internal memory, so mass storage is not an option either. It shows up in Device Manager as "Google Galaxy Nexus ADB Interface" under "Android Device"
Things I've tried:
-Rebooting the PC(Many times)
-Rebooting the phone(Many times)
-Powering off the phone, taking out the battery and leaving it for 5 mins then powering on again
-Reinstalling Samsung Kies and Samsung USB drivers(infinite times)
-Factory resetting the phone and skipping all account prompts at startup then connecting the phone(seems to work for some people)
-Connecting with USB debugging off
-Connecting with USB debugging on
-Changing the USB Port.
Please help, I'm just about sick of this phone and it's countless issues, can't believe how hard it is to customize.

So here's a development. I tried turning USB debugging on and it installed some drivers then restarted my PC, now MTP mode works but only when USB Debugging is on, so at least that's good.
Still if anyone knows a way to fix this(ability to connect via USB with debugging off) that would be great. I don't imagine it's safe to have debugging on all the time.
Edit: also I got an idea, if there is a way to run the Phoneutil thing on CM10 that would be wonderful, I probably need to change the qualcomm USB settings from there or set those options in the main menu to PDA/PDA. The *#7284# code doesn't work without touchwiz.

I believe this is what you need.

Seen the post a while back, wasn't hard to conduct a quick search. You're not alone on the MTP hate boat.

Thanks man.
Would you mind explaining that permissions bit though? I don't quite understand it. I've found the folder and can't delete it because of the permissions but I can't understand his explanation of getting the permissions... lol.
EDIT: I can't find "upperfilter" either.
I had to change permissions on that object to do so, then inside permissions take ownership and tick child keys and subkeys
Uncheck inherit from parent
If it pops up a dialog pops up choose add from the options
You will have to do this for several tabs in this permissions of the registry.

Well, windows sucks on that department. The process is a bit buggy and shows you WAY too many warning and unnecessary windows. So this is what you need to do. After locating said registry key, i'd advise you to export it (it's a backup).
Then try to delete it's contents. You've noticed you can't, it says permission denied. So you right click on the denied folder and chose permissions.
You'll notice it's all blank. Press Advanced on the bottom and you'll notice on the next windows, up there where it says Proprietary, it says you're not the proprietary. But there's a placeholder link that does allow you to change who is. Click it and type in (search if you need) your current windows username (assuming your username is an admin on that machine). Accept everything util you reach the first window you got when you chose "permissions". Instead of pressing "Advanced" you pick "Add" and add your username again, give yourself "Total control" on the tick boxes below and press OK. You'll be back at the registry keys. The process to pick up the new permissions is a bit buggy. You'll need to refresh them now and you won't be denied access to the contents of the key you've just altered but you'll find out another key where you need to repeat the whole deal again. Think this'll happen 3 or 4 times. When all's done you will have no trouble deleting everything.
Now, this is the part i managed to do. My control panel part, is no where like what was stated in the OP (maybe because i'm using win8.1). I'm still figuring that one out. Removing the reg key, seems to have had no effect whatsoever in connecting my device to the computer, everything still works albeit through MTP.
Oh yea, i never had an issue with MTP not working. I just want to remove it because it's a limitative uneeded piece of crap. Slow transfer speeds and blocked access to my stuff during an operation (copying stuff) is just retarded.

Thanks. I just found a huge timesaver called run as system that opens any exe as the SYSTEM profile, so you have sufficient permissions to delete whatever you want.
I removed the whole folder and the issue persisted, then I don't know what I did and USB stopped working completely, with and without Debugging. Gahhhh...
I'm recovering the original firmware now and starting from scratch on this.
Will post any updates/progress.

I DID IT. 6 hours of pain, I finally fixed it. Guess what the big thing is? Outdated ****ing drivers... god.
The drivers in this thread are outdated and do not work for androids past 4.1:
[WARNING! + GUIDE] Backup and Restore IMEI / NV Data Procedure for GT-I9305
Do NOT use the USB drivers from this thread.
For anyone having this problem:
Uninstall Samsung Kies, at the end you'll be asked if you want to remove usb drivers as well, accept.
Uninstall USB drivers from to make sure they are completely gone
Reboot your computer
Reboot your phone (doesn't make sense, just do it)
Reinstall Samsung Kies
Install up-to-date version of the drivers, look up version 1.5.29.0, filename SAMSUNG_USB_Driver_for_Mobile_Phones_1.5.29.0.exe (Not posting the link because I'm not sure it's clean, don't want to infect anyone)
Plug your phone in
Ta da! You can now transfer files from your computer to your phone and vice versa using the DREADED, ABYSMAL ****ING Media Transfer Protocol
If this does not work, redo the first 2 steps, plug your phone in while you have Device Manager opened (Right click on my computer then choose Manage) and look for any devices showing up after you plug it in and uninstall the **** out of them, removing their drivers as well, make sure you do this with both MTP and CTP(Camera mode).
After that proceed from step 3 and you should be good.

Can't connect to Activesync

i need some help
when i connect the usb with my tilt
it just charges the phone
You want to give a little bit more information?
Yes, that would help. What happens when you connect and what version of active sync do you have and what Windows OS are you running?
Step one: make sure you have activesync v. 4.5
step two: disable your norton or mcafee or whatever virus protection you have
step three: go to start, control panel, switch to classic view (on the left side) click on windows firewall and disable it.
it should connect at this point.
leave the device connected and disable one at a time when you hear that little activesync noise you've found the program that was causing the problem. Ta Da! let me know if that works. PM me if anything else.

Hmmmmm, hard reset or in device manager check for your device's driver and delete it, then try again.

r u asking me to removed all usb drivers?
coz it doesnt say which one is which
Sometimes this is a simple cable problem.
Try a different USB Port on your computer, or a different cable. Also check that you haven't damaged the USB connection on your phone (some people do this by poking it with their stylus when trying to soft reset).
I had a similar problem, no idea if it is the same or even similar, but with mine RAPImgr also locked up and spiked the CPU usage to 50% (ie maxed out one of the cores - have a look in task manager). This only started happening with my Kaiser, wasn't happening with the Hermes....
Anyway, the way I solved it was to go to Start -> Settings -> Connections -> USB to PC and disable the "advanced network functionality" (ie uncheck the box).
If I had already plugged the phone into the computer, rapimgr would already be locked up and the only solution was to reboot (killing the process spawns a new one and when you finally find its parent's parent to kill, it takes out something vital which causes the machine to force a reboot).
For it to connect to my Vista box, I have to have this setting enabled. For XP I have to have it disabled.
Hope this is of some help.
I too was having this problem - i uninstalled ActiveSync from my PC and reinstalled it from the MS site - works fine now.

File Transfer Problem?...

Hey everyone, kinda new to htc phones...or rather, smart phones in general, and this diamond touch is my first, just got it...
Anyways, im not a total "noob" or anything when it comes to phones, but i can't figure out if im just stupid and don't know how to transfer files onto my phone via usb, or if there is an Actual problem....
I have my "USB To PC" Settings set on the "Disk Drive" setting, and when i plug my usb in my phone > PC i dont get any messages saying anything like the usual "Mass storage device found" etc. etc. on my computer, all that happens is a little PDA looking icon pops up in "My Computer" and when i go into it there is nothing there, Nor can i create anything in it.....
So needless to say im at a lost...i know i could just transfer music/videos and stuff via bluetooth, but that would take a VERY long time.....
Anyone have any suggestions?...
More Info:
- Yes i installed the disc it came with
- Running Windows XP Pro
- Tried soft re-setting
EDIT: Ok i take that back, that PDA looking icon is there 24/7 i thought it just popped up when i plugged the phone into my usb drive, but i guess it's always been there since i installed that disc.....so, literally nothing happens when i plug it into my computer :S...
Any help at all?...
for real...

when you plug in usb and choose 'disc drive' on your device, you should go to 'my computer' and your pc/desktop and select g-drive, or e-drive, or one of em, open it, and you will see the folders/contents of your device 'internal storage'/storage card.
this thread is old, so I'm guessing you've already got it figured by now.

[Q] USB Tethering

I use my Lumia 920 as my main communications device with unlimited internet/tethering from my provider. The Wifi internet sharing feature works fine but is a HUGE drain on the battery. Plus I have concerns about the safety of wifi!
Ideally I wanted to tether to my computer using USB but there doesn't seem to be a lot of information about regarding this with WP8.
Has anyone found a way to do this? Have I been missing something obvious?
I would recommend against using your phone as a router, it will simply die a lot faster due to high hardware stress.
http://microsoftarena.net/usb-tethering-in-windows-phone-7/
WP8 should be similar.

Thanks for the link, unfortunately, this doesn't work on either the Lumia 900 or 920. Nokia don't seem to have built the option the same as Samsung.
As for the hardware stress, thankfully in the UK we get a 2 year warranty! It'll be up to Nokia to repair/replace if my phone dies using one of the built in features
For the record, wired tethering does work on the Samsung Ativ S. The trick was finding the drivers for my 64-bit PC.
First, you need the Diagnosis app for Samsung phones. This is included, but hidden, on each phone. To access it, type ##634# (##MFG#) into the phone dialer. After it's run once, you can launch it from the Apps list like normal.
Next, to access the USB control, type *#7284# in the numpad that the app displays.
Select "QC RmNetComposite" from the USB Path Control radio button options. This will take the phone out of its default MTP (Media Transfer Protocol) mode, and make it act as a Qualcomm USB modem. The phone will need to reboot when you select this option; let it do so.
When the phone boots up again, it will not appear in Windows Explorer or the Windows Phone app. You'll get a "Found new hardware" notification, but the odds are that the drivers will fail to install automatically. We'll need to install them manually.
To do that, first download the attached ZIP file included with this post. Extract its contents somewhere handy.
Next, open Device Manager. This can be done from the Start menu/screen, or by opening Computer Management, or by typing "devmgr.msc" into Start search or the Run dialog and then hitting Enter. It will require Administrator permissions.
You should see four "Qualcomm composite device" entries that don't have drivers. We only need two, maybe even one, of them. It's possible to tell them apart, but for simplicity's sake I'm just going to tell you to do the next steps for each of them.
Double-click one of those entries, or right-click on it, and select Update Driver.
Choose the "Browse" option, and navigate to the folder you extracted from the ZIP file. You don't have to go any deeper, so long as the "Include Subfolders" option is checked.
Hit Next and, if a warning pops up about unsigned drivers, choose to install anyhow. There is actually a signature; the drivers will work on 64-bit Windows. I don't know what that complaint is about. If it just says that it couldn't find a driver, that's fine; that's one of the two devices we don't need, probably.
Once you have the Qualcomm USB Modem and (possibly) Qualcomm Diagnostics devices installed, you're ready to configure the modem in Windows. To do this, open Network and Sharing Center (or Network Connections in XP) and chose the Create new connection option.
Select a "Dial-up connection". Don't worry; it's neither as slow nor as noisy as a classic modem.
This next part is probably carrier-specific. For T-Mobile US, it was ridiculously easy: type a name for the connection (doesn't matter what), in the place for the number you dial, put "*99#" (without the quotes), and leave the password and username blank.
Try to connect! If it doesn't work, look up the WP7 settings for wired tethering to your carrier; they should be on this forum somewhere.
When you want to get back to normal (MTP) mode on the USB port, just repeat the first three steps but choose "MTP Mode" instead of "QC RmNetComposite" and let the phone reboot again.
Something which may help: I found that the PC would lose data connection while the phone used it. To make the PC's data connection more reliable, turn off data usage on the phone. The modem should still function. There are a ton of other tweaks to configure the modem driver which might also help, but for basic usage, the steps provided here work.
I recommend copying the driver bundle onto your phone (or its SD card) so that if you need to tether a PC that isn't already set up, you can get the drivers without needing Internet access. It's quite possible to copy Zip files to and from the phone via MTP mode.

my htc 8x dosent work with these code ##634# work but *#7284# doesnt work
these drivers don't seem to work for windows 8.1. Any idea where to get them?
No, sorry. It took me hours of searching to find them for Win7. They should, in theory, be pretty standard drivers; you could maybe find ones that work for an Android phone with the same Qualcomm USB modem and tweak the INF file to get them to install for the Windows phone. I don't have an easy solution, though.
The USB tethering code (*#7284#) doesn't work on my Sprint Atic S Neo. Is this a known issue on the Sprint version of this phone?
For some reason Windows 8 x64 doesn't like these drivers. It complains there isn't a hash for the file. I guess back to test-signing mode....

Thanks for the drivers
I found it interesting that additional features appeared in Ativ S T899M after diags turned on (##MFG# replies with Odyssey_121205 on diagnostics page) EXCEPT the ability to gain better control of APNs.
With my Ativ S (T899M again) the #7284# does nothing when entered into the diagnostic app.
I was wondering if there is a decent listing of all (or at least some) of the diagnostic codes.
whoops!

There's even more things hidden in there that's available by using the native toast launcher in the hacking forum.
I have a Sprint ATIV S Neo and *#7284# does nothing.
However...
##3424# takes me to the proper screen (Micro USB Test).
Still haven't found drivers for 8.1 yet though...
You'll need to use the Native toast launcher to bring it up.

Hi everyone, especially the writer of the quoted post, i know this is a old post but i just want to tell how to install the driver on Windows 8.1 64 bit in case if someone ended up here.
Windows 8.1 64 bit won't allow users to install unsigned driver like the driver he attached (Actually, the driver is signed, but i forget the reason why windows recognize it as unsigned driver. Please refer to the previous post). So, to make windows allow that, use this instruction:
http*://www*.howtogeek.*com/167723/how-to-disable-driver-signature-verification-on-64-bit-windows-8.1-so-that-you-can-install-unsigned-drivers/
nb: remove the star. i'm new here, so i can't post a link.
After you follow the instruction, then install the driver as the guy described.
I've tried this method, and it's work!

Ok, i've figured it out. Here is a link to my post.

my main problem is "Device handshake failed"

Hi folks
this is the first time for me with WP 7 i am with the Android since the G1 lol.
i got an a focus s from a friend and i said to my self , why you don't try it? its locked to at&t, so the first thing i have to do is unlocking it.
at that point the problems started!!, i checked the unlocking cost via code, the average is 30$ which is expensive for 80$ phone!!, so i choose to unlock it via fastgsm and unlocking via USB cable.
i followed the instructions and everything seems to be OK till the last step when the phone reboots to the download mode, the program shows "FAILED" i had contacted teh customer support for fastgsm and they tried to help me, with o hope, thereafter i didscovered that there is somethign wrong with the connection of teh phone to the PC.
i start to read and read and read again "noting that i am expert in android things" and finally i decieded to use the CAb sender and/or the "sharp7eighter' to update then SIM unlock.
both programs with the same error "Device handshake failed" noting that the phone is connected and shows i937 in my compute but it never ever recognized by Zune, always says "no device connected"
sorry for my bad English, but i am very sure there is something i can do to :
1-go back to stock
2-update my phone
just to connected the fastgsm program to be able to SIM unlock it at acceptabl;e price 15$.
please and thanks

Fastgsm stopped working with the focus s when the newer firmware got updated, I think it was version LE2, I know I had to pay for more expensive unlock although in theory we can achieve unlock without paying anything with gsmtools etc, but this is risky as I don't really know how, it would require some experimental work!
As for connection issues
On keypad of your phone type ##634# and click "Call" button to show Diagnosis screen.
Type *#7284# onto Diagnosis screen, select "Modem, USB Diag." For fastgsm, and "zune" for...well, zune and confirm selection
Restart and let me know how zune sync now works

so, the safest way is pay the 30$, correct? noting that the firmware is in the attached pic

Its zune, Not zune diag, select the top option and reboot, it should work then

OK, there are a bunch of things we are going to try
Firstly are you in a position to hard reset your device from the boot loader?
If so do it, If not turn it off instead
turn your PC off
Plug USB cable in to a different port on the back of your PC, do not use a hub, it has been known that some hubs can affect sync
Turn both pc and phone on, assuming you have used a different USB port windows will install new drivers
Load zune and try again

i didn't use the phone yet, so i have no data to lose.
for the hardrest i did it many times, from setting , about, reset your phone then turn it off, press the three buttons together (power+camera+vol down) and format.
i don't know what you mean by headrest via bootloader.
and i changed the USB port and used 3 different types of USB cables, with no hope
and the strange thing is, when i plug the phone, the zune starts automatically and shows no device connected !!!
i am very sure that the previous user for the phone manipulate wit the software, so all i am trying to do is revert to stock, and i have another question regarding the download mode, when i was using the USB method from fastgsm to SIM unlock (screenshot attached), it shows that the PC detect the phone and read all information, but when it restarts to the download mode, it "FAIL".

I think its connected as a MTP device, that probably explains it..
OK,
Im going to hazard a guess with drivers being the problem
with the device connected I want you to do in to device manager and uninstall the driver for it, make sure you click delete driver as well.
then Disconnect the device before it can start installing it again
then go to http://www.nirsoft.net/utils/usb_devices_view.html and download the program at the bottom, make sure you choose correctly between x86/x64
this little program will allow you to view and delete all USB devices connected past and present. basically select the device, right click and uninstall it, you will need to run the program as admin
Have a field day and delete anything and everything that might be related to the phone, if you whack something that isn't related all you will have to do is reconnect it and it will install the drivers again so there isn't much to worry about.
try that and see if that removes what I think is a driver conflict. mind it might not be obvious what is and isn't related so best err on the side of caution and keep only those that definitely are not it!
Note it might be Samsung, or i937 or Windows phone or WP7 or more annoyingly USB composite device of which you will have many, just mind one of these will be a keyboard and mouse, if it stops just unplug and plug back in, windows will take care of the rest

Question Connection & Transfer Issues/Problems: Snapdragon S21-Ultra-128G Factory Unlocked directly from Samsung to Windows-10-Home PC Laptop.

Using USB-A as well as the USB-C the phone is connected. It reads the phone, but only pictures, videos, and audio files can be seen on File Explorer, not docx, pdfs, apks, zips, or exe files, etc.. Apparently the PC/Laptop only read the phone as a Multi-Media Device.
Can only transfer Media files from Phone to PC. Can't transfer any files from PC to Phone.
No issues with other phones: s9, s10, or s20. Even tried other brand new laptops running recent Windows-10, same issue.
I have uninstalled and re-install the Samsung USB Drivers. Windows 10 automatically updateed the drivers just for it to remove the "caution" symbol in the Device Manager as a multi-media device.
Is it a Samsung issue? Or is it a Windows issue?
Any help would be appreciated. Thanks!
After updating optional Samsung updated drivers on Windows 10. That did allow me to bring files over to the laptop. But I am not able to carry over files to the phone.

try with another cable

Thanks for the reply. It seems to do the same thing even when I use the cable that came with the phone. Could be a Windows 10 issue?
This is a 4-year-old laptop that's been acting rather strange since the Windows 10 updates the past few months. It's about time for a factory reset anyhow. Hopefully it will work after the reset.

That didn't work either. I even did a factory reset on my laptop and still the same. I will factory reset the phone and maybe that will fix the issue. (Is there a possible setting in the phone that can cause this?)
FYI, pictures on my phone in the file explorer can be seen, but files like APKs do not show up as if they are not there according to the laptop file explorer, even when I try to view hidden files they don't show up.
Maybe this helps https://www.diskpart.com/articles/s...move to further,Disk Management and try again.

Thanks for the help. Unfortunately none of these worked.
Even on a friend's brand new windows 10 laptop of a different brand, still have same issues.
Remember, my phone is connected. But, certain files like APKs are not even shown. I can transfer the files that can be seen to the Laptop. But I can't send any files from PC to phone whatsoever. It will show the transfer window, but after about a minute, the window will close with an error beep/alert and the transfer will stop.
Seems like only pictures, videos, & music will show on the file explorer, not apks, zips, or software type files. No issue with older phones on s20, s10, etc..

It seems that PTP option is set by default, maybe you can check in the dialogue under developer options that by default is set to transfer files.
Also you should disable all the related security actions over USB under security and developer menues..
In the meantime till you can solve it you can transfer some files through adb push command, it´s a little tedious but can save you by now. Also is the app Link.
It´s really strange some time ago without trying exactly everything though I couldn´t communicate my A70 with PC but then for other reasons I did a clean installation of Windows (not using preserve files and apps) for repartitioning purposes and surprisingly it started to work just fine.

Thanks for the advice. None of the above helped. Maybe just have to wait until the next Windows 10 or Samsung Software update, and go from there. *Shrugs*
Update: It seems to only connect as a Multi-Media Device. I'm guessing that is why it only shows Images/Vids/Music. Nothing else appears on File Explorer, not even docx or pdfs. I can only send the media files to the PC but no files can be moved into the phone.
any help would be gladly appreciated!
Thanks to all those who tried to help. After doing a factory reset on the phone, as well as a the Windows Samsung 2.17 USB drive update. Everything works fine now.
