Unstable and lost PC connection - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

I have upgraded my Samsung galaxy tab 2 10.1 tablet, GT-P5110, to Marshmallows with a Custom Rom, CM13. A smooth process. which appeared successfull. However with two problems. The system is very unstable. It crashes and restarts frequently for no obvious reason. This behaviuor is so disturbing that the upgrade must be considered a mistake. Is there a remedy?
Also I cannot t usb-connect to a W10 PC with the driver installed via Kies. A unit correctly labelled GT-5110 appears (icon displays a music device!!) but the folder, expected to show the files, is empty. The unit is clearly not identified correctly. USB has been set to MTP on the tablet. Trying the Samsung MTP driver available in W10 does not help. I have also enabled Android debugging (ADB) in the tablet with no difference. An error in the CM13 installation? Or is a different Samsung driver needed? I can get around some the problem by using the networking capabilities of the ES filehandler but still the error is annoying.

[Q] Connecting android tablet as testing device

Hello everybody!
I have a problem related to connectivity between my desktop (Windows) and tablet (Android 4.1). I bought a new device (Colorovo City Tab Vision 7) and now I want to use it for testing of my applications, because emulation of android is very slow on my computer, although I forced it to create snapshot every run.
I have downloaded SDK with Google drivers and also some unofficial drivers I found on web. When I connect my device, it first appears 'Other device' (label is CTVision7) and it's marked as unknown. I tried to install drivers (Google) for it, but windows said that they aren't suitable for my device, as it's not able to find them in specified directory.
After these attempts I tried unofficial drivers. Their installation worked and now my device appears as Android phone, what seems to be good.
But when I run
Code:
adb devices
or launch application in eclipse, there's not avaible device.
I have turned USB debugging on, so it should work.
Am I missing some step to make my device avaible for debugging, or are my drivers wrong? Is there any way to get drivers which surely work?

MTP driver apparently OK but not in explorer

Hi, I recently changed to Win 8.1 (x64) and for some reason the OS is not recognizing my phone or my tablet (both have MTP interface).
Apparently the drivers (MTP & ADB) are correctly installed, I see both of them on the device manager with no errors, and I can even connect through ADB. Also, in the devices and printers site I see them under the unspecified type. I also see them on the safely remove menu (but the icon is a generic device, not a multimedia one).
I've tried countless solutions, and also all types of drivers. Sometimes I get error 10, sometimes nothing.
I've read one solution that is to install the media feature pack for N versions of Windows but that's not my version. But then I remembered that I messed up with the system codecs not long ago. Maybe there is a connection?
Apart for MTP and ADB devices in device manager, I have a hidden device under "other devices" category with the name of the phone (GT-I9300 in this case). That's the name that should be seen on the explorer to access the phone's files.
Anyway, I can't explorer any android device through MTP.
Any solution or approach to find the error?
I will provide any info you guys need.
Thx in advance!
Anything? I've been trying things literally all day and I'm starting to feel very fustrated...
I've tried this:
http://forum.xda-developers.com/galaxy-s3/themes-apps/guide-troubleshoot-mtp-driver-t2518821
And nothing at all. It's not the phone because I only changed from win7 to 8.1, I did nothing to my phone. And also it's not just my phone, also my tablet or any other mtp device. Also, the driver seems to work well on device manager, the problem is that threre's no device in explorer to open it.
Any ideas??? I'm freaking out!!
Problem solved. Guess what was the cause: the Media Scanner Optimizer Xposed module. Don't know why though. If anyone knows how to fix it please tell me, otherwise it will remain deleted from my phone.
Thanks.

What should the USB port of an S6 or T705 look like to a PC?

I have
Samsung S6, 5.0.2, rooted
Samsung T705, 5.0.2, rooted
I have the USB drivers installed - the ones you need to flash with ODIN.
The S6 is not recognised by the PC at all via USB.
The T705 presents via USB the following directories
http://peter-ftp.co.uk/screenshots/2015-10-25-191104.jpg
so works as fully as expected. The directories are R/W as they should be.
Is this normal?
Is there any way to access the phone's stuff over USB - at least the DCIM directory (photos)? Presently I can do it but only over wifi (various methods).
The computers I have here all run winXP SP3 but the fact that the T705 works fine suggests that win7 etc would not help.
I think you need to reinstall the samsung usb drivers:

I did - makes no difference. I even installed the S6 specific ones. The T705 continues to be visible but the phone isn't.

Transferring files (MTP) doesn't work

Hi.
LeEco 2 Max (4/32).
ROM: ResurrectionRemix-MM6.0.1TeaMSpaiN-LeMax2
Rooted.
USB connecting is working (works transferring photos [PTP], works battery loading).
But I can't add other files (music etc.) from computer to LeEco.
I checked on other laptop: works fine. So problem is in my laptop (Asus), maybe with drivers.
What should I install to fix it?
"AdbDriverInstaller" doesn't see the device also (in every mode).
Do You have any ideas?
It isn't important problem, you don't need to fix it.
Not important for You, important for me. That is why I am reading about this, right? Not for fun.
Problem is important: I can't copy music or audiobooks on device.
If You can't or don't want to help, don't help. Easy.
Did you already solve the problems? there should be an option to update the Android drivers by plugging the device several times in. That's at lest how I've installed my Le Max 2 for the mtp process. After those drivers have been installed automatically, my laptop recognized the phone withoit a problem
No, I didn't.
You're right it should be automatically (like on my other machine).
But here I have problem. On Huawei Ascend P6 I knew I should install HiSuite and for few hours everything will be OK.
But not here.
Maybe do You know something like HiSuite for Huawei but for LeEco?
I don't know if it would help, but when you connect the phone to the laptop, go to device manager and uninstall the driver found for the device, then unplug and plug again. The driver should come automatically, at least in theory, and hopefully the good one.
I need to say that I've had an issue similar to your long time ago and it was due to windows. After reinstalling windows again, the problem was solved. I know now nobody does this, but at that time, this is what helped.

The same thing is happening to me...
I plug the mobile to a pc (windows 10, windows 7 and kali linux) by usb and it's only capable of charging; neither MTP, nor ADB, nor OTG...
Heyyo @zaroc, is that with TWRP or a ROM? Please provide which versions they are

Issues with connecting Redmi Note 4X to Windows 10

Hello. I'm a happy (?!) user of Win 10 Pro x64 since few days.
I want to connect my RN4X Snapdragon to PC, using usb on my pc's motherboard.
However, despite setting option, that I'll listed below, my phone is still not recognisable as useful stuff.
Without changing anything on my phone since my last flashing topics (Feb and March this year), I was fully able to connect easily to pc with win7 x64. I also was able to connect (using Xiaomi's cable, cheap replacement does not seem to work) phone to win 8.1 x64, where only the basic adb fastboot were installed. But, I cannot do the same on newest Windows.
I've done:
1. Installing minimal adb and fastboot 1.4.3. for all users (I'm the only one account here, but not sure if that's matter)
2. Having programming option enabled, usb debugging enabled and all that good stuff.
3. All four elements on that list - https://************/how-to-fix-mtp-devices-not-connecting-on-windows-10/
4. I've tried to install it as adb interface, installing it manually, installing it by using *.cat files from xiaomi_usb_driver archive, that contain that kind of stuff for newer windowses (it's from this side, if I remember it right - https://www.xiaomiusbdrivers.com/2018/02/download-xiaomi-usb-driver-2018-for_4.html)
5. Almost all stuf from here - https://www.jihosoft.com/android-tips/windows-10-cannot-recognize-android.html. Because I do not have Samsung, Odin mode is not an issue
6. I've tried to install my Redmi 4X as MTP device. However, my phone during each connection to PC started himself in charging mode (I can change it). Even changing it doesn't changing anything, though.
7. Editing the bulid.prop, adding there few lines describing how the phone should behave. I've saved it, but my original version of bulid.prop does not have anything in there about types of connection. I don't remember it word by word, but I've could check in history if anyone will find it interesting.
Drivers for usb 3.1 are pre-installed with mine version of win10 (I cannot install drivers given on my motherboard's dvd attached, system says that I'm currently having them).
When I try to install it manually via device manager, on the first time it says, that is other device, identifed briefly as MTP. However, installing it either as Android ADB interface, fastboot interface or third option does not give me anything. What's worse, even when I've pick windows/INF as my source of drivers for this device, it does not list on "lemme pick ddevice type" MTP type devices. I'm using win 10 in polish, so it might be that I'm blind or does NOT understand translate.
What else could I do? I can of course use wife's laptop with 8.1, usb sticks or other stuff, but I would like to have it sorted out.
Does otg still works to your device?

Not sure. How to check it? We use to have 16GB OTG to USB2.0 (other end was micro usb B), but we must have put it somewhere during moving out to new flat, cause I cannot find it now.
gonna bump it, cause there's not any clue yet.
Same here.
