Hello,
first of all I'm not the man who can make a new and highly 'must have' app for my device. I only have a problem but it seems only one of you can help me on it.
I wanted to use an usb-otg-device (camera) on my cell phone but it doesn't work. I found out that usb-otg is the problem (I even didn't know before that it exists) becaus it is not activated on my device. So I wanted to try out how to change this. Information on otg is hard to find since the community mostly seems to assume that all cell phones out there have this feature and a special cable is needed so all answers on such a question goes on this cable. I just not able to find out which devices allready have this (it is not mentioned) and I have the evidence that not all types of cell phones to be sold nowadays have it ... my smart phone I have.
So I wanted to see if I was able to make my phone have this feature by hacking the os on it. Now we will come to adb from the package. I wanted to see if the proper module for the kernel is anywhere there and how to make the device loading it at boot. I just don't know if the usb curcuit is able to do it this way but without the proper driver it's not important. And if the driver is loaded and it works not anyway I really have a problem. But first of all I have to activate the driver (hoping it is allready able to work with a curcuit with no otg ... just as the normal driver; a thing I have to find out too). But the first thing I have to do is to find out what is happening at boot, which is the design and options the kernel uses and so on.
But now my new problem: adb shows an empty list of devices at the pc even the driver has sounded at install. The cell phone is set for developers and usb debugging is on. I plugged it of and on and start 'Minimal adb and fastboot' the device is not plugged in and also with the device allready connected but that is no defference ... adb devices shows an empty list.
So: How can I access my cell phone?
Thanks and excuse me if this is allready answered ... I didn't found any thread

Hi,
I realize that there might be an answer to this already, however I have been searching for a while and no such answer has presented itself. I have come across other threads on this forum that explain how to get in. However my concern is that these are really old posts and perhaps point to an older version of Android?!? The reason I didn't follow those tutorials is I am afraid of wiping off any data that might exist on the phone (which is not something I would like to do!!!)
So it is as follows:
LG NEXUS 4 - 02 NETWORK UK
NOT ROOTED
STOCK EVERYTHING
USB DEBUGGING DISABLED
CRACKED SCREEN\DIGITZER - NO TOUCH RESPONSES ACCEPTED
So my question is this, can I access the files on here including all music/photos/contacts/messages etc and back up to a WINDOWS PC. Please forgive me if my responses sound noobish to you, as I am not familiar with Android, so might ask some daft questions.
Thanks in Advance
Anybody? I fear for trying anything as I do not wish to loose pictures etc.
Stock Everything
Not Rooted
No USB Debugging Enabled
Can I enable usb debugging through adb?
you do not need usb debugging enabled to transfer data from device to pc, my question is, when you plug your device into your pc, does your computer recognize it as a mass storage device and can you see your phone in the list of devices with removable storage ?
Cant turn on usb debugging after system update even when its plugged into the pc it wont turn on.. i can still transfer files from phone to pc and pc to phone im not sure whats going on here. Theres no bug reports either and you cant verify apps over usb..

Do a factory reset ?
That didnt work it hasnt worked since day of the system update and that was on a fresh install of the rom before this one.. i think thats just how the system update is...

I made this video showing settings and dev settings in the boost mobile j7 after system update... kinda give people a better look at whats going on. I posted it to the public on Facebook so hopefully it gets out to the right people..
Heres a screen recorder that works without root..

What Is USB Debugging Mode On Android? [MakeUseOf Explains]

usb debuggingIf you use an Android phone and you’ve searched forums for solutions to problems, you’ve probably heard the term “USB Debugging” every once in a while. You may even have seen it while looking through your phone’s settings. It sounds like a high-tech option, but it really isn’t; it’s quite simple and useful.
One beauty of Android is that it has a lot of built-in features, many of which are advanced. If you want to supercharge your phone with mods and whatnot, you can; if you want to use it just as it was out of the box, you can ignore the advanced stuff. USB Debugging is a feature that all users can benefit from, though, so you should know what it does and when to use it.
What Is USB Debugging Mode?
USB Debugging Mode is a mode that can be enabled in Android after connecting the device directly to a computer with a USB cable. The primary function of this mode is to facilitate a connection between an Android device and a computer with Android SDK (software development kit). As the name might suggest, Android SDK is a software suite that’s designed to aid in the development of Android apps.
Ever wondered how a programmer creates apps on the Android? They definitely don’t code them straight on the phone device! That would be nightmarish at best. Instead, they utilize the environment of the Android SDK to code apps on a computer, use USB Debugging Mode to transfer those apps to a device for testing.

But, again, here’s the takeaway: USB Debugging Mode establishes a direct connection between an Android device and a computer and readies it for deeper-level actions. That’s the important part.
In some versions of Android, the USB Debugging Mode feature may be called Developer Mode. With such a name, it can be easy (and reasonable) to think that you’ll never need to deal with this aspect of Android if you never plan on developing anything. That’s not exactly true.
Why Is USB Debugging Mode Important?
USB Debugging grants you a level of access to your device. This level of access is important when you need system-level clearance, such as when coding a new app. However, there are a few non-development-related benefits from this new level of access that can give you much more freedom of control over your device.
For example, with Android SDK, you gain direct access to your phone through your computer and that allows you to do things you normally couldn’t, like snag instant screenshots of your device or run terminal commands with ADB. These terminal commands can help you restore a bricked phone–a useful tool for any adventurous Android owner. Without it, you’d have to get a replacement phone.

USB Debugging is also necessary if you ever want to root your Android device. Before an app like One-Click Root can dig into your system and deliver the exploit that roots the device, USB Debugging is necessary to allow that function in the first place.
Yes, the original intention for USB Debugging Mode was only meant for developers who needed to copy data between their computers and Android devices, to install apps on the phone without notifications, and to read log data off the phone. But even if you aren’t a developer, you’ll probably run into a few apps that require USB Debugging Mode to function properly, so this mode does affect you and you should know about it.
Start searching dialer codes for Samsung devices and do be careful on what you do in those service menus.
-sent from this device using this app.
Just tried that and cant get any codes to work in the dialer or in the apps.. and one says im missing su so i dont know im about to just flash back to the older firmware Security is nice and all but damn they killed it.
I found the problem it was samsung knox if you activate it or use my knox app it disables your dev settings so i ripped knox out of my phone now i have usb debugging..
I've been having this problem for a long time, can't remember how much exactly. No matter what I've tried, I haven't managed to get my computer recognize my opo. I am still running Cyanogen 13.0, as it was the latest OTA update I got.
When I connect it via usb, absolutely nothing happens (I've also tried two cables). I have the device manager open and it doesn't even flash as it used when I had similar problems, which means that the device is not recognized at all. Therefore, I cannot find/update/remove the drivers anyhow.
Developer options on my phone have a bunch of things but none seems relevant, apart from open/close Android debugging (adb) and select USB Configuration (Charging/MTP/PTP etc). I've tried several options, nothing seems to change.
I've also installed some Windows MTP drivers (see here) which were supposedly solving the issue caused by a Windows 10 update, but no luck (which could have been the issue, but can't be sure-I can't remember the last time I was able to browse my phone's memory).
Any ideas?

If win10 causing that much issues,why don't dual boot win7 alongside?
Edit- I personally use Win8.1 Pro and it works fine without any issues.
I've been running Windows 10 insider builds for a while and run Into the same issue at some point, I'm not sure on which build you are currently on, I've reported that on the insider HUB but got no reply. I found a "solution" which is selecting PTP in the options and the phone will be mounted as a media device and you'll be able to access DCMI folder and pass files. It doesnt mount always, but you need to try some extra times.
Another workaround is to use an USB drive and the use an OTG cable.
Apparently, it was just the cables' fault. I didn't figure it out immediately, as I had two faulty cables instead of one, but after all I came over a working one and the opo was recognized and mounted as usual.
Thanks anyway

I wish I had the same issue ?
I'm posting cuz I've literally spent hours and hours searching, trying things, etc, and am stuck. I have several PQs with various CM/LineageOS ROMs. It is not a ROM issue because if I plug via USB into my desktop pc running win 10, they all work as I want. Presumably, it's a driver issue or something related to my specific laptop - I recently bought an old used laptop, originally shipped with win7. After purchase I immediately removed all partitions and installed win10 from disc (fyi, you can d/l win10 iso from microsoft and use win7 oem key to legally install fresh win10, even now the free upgrade stuff is over - that surprised me).
I cannot, no matter what I do, get file access via usb to my phone. I've tried lotsa things. I don't remember if/what I had to do to make my win10 desktop see them - maybe it was automatic, i dont remember, if it wasnt, I easily downloaded/installed what was necessary - but nothing I've tried makes my win10 laptop load the drivers, although it does detect something when I plug it in, and something else when I select MTP on the phone (vs charge). But just exclamation points in device manager and nothing in explorer. Among other things, I've tried MotorolaDeviceManager_2.5.4
It's especially annoying as I have a video on my phone I wanted to send out tonite and can't, spent another couple hours trying. Bluetooth works fine for pictures but freezes at 10% for video, no idea why. But I'd much rather just use a cable than figure out any wireless BS.
Incase it's something specific to this laptop and someone is curious, it's a Sony VPCF115FM. That 'base system device' and "unknown device" are always "!", MTP with "!" only appears when phone plugged in.
Yea definitely a driver issue. When you plug the PQ into your desktop (which seems to work) what shows up in device manager?
Have you tried to right click on the devices with yellow exclamation points and update the driver from Windows update?
I never followed up on this, but still haven't found a solution, and kinda forgot about it. It does work in PTP mode. And works for a newer Moto (Lenovo) phone on this laptop. Yes, I tried the windows 10 device manager update auto search thing (in fact, just tried it again minutes ago before I read this). I'm about to wipe and install fresh as this phone is running crazy slow lately and wanted to copy everything off before I wipe which is what reminded me of this issue - funny thing is that a google search of this problem ("mtp driver motorola photon q windows 10") found this thread as the third search result and I completely forgot I posted it. I vaguely recall I read your reply but was waiting to see if anyone else responded and then just forgot to follow up when it wasn't on my new list...
PROBLEM SOLVED! It happened in TWRP too and sideload was failing (for another reason) but made me try to figure out MTP again.
Found solution here for anyone with similar issue:

Gotta update driver and manually select "MTP USB" from list of devices, in my case I found it under portable devices.
I have a device that's evidently called an Edge Mini tablet purchased from the prison system while I was incarcerated. Known issues are battery explosions as mine did. All I have is a circuit board in which Device Manager on pc recognizes something briefly and disappears.
I spent nearly $2k on music and would like to find help on retrieving it somehow.
All I know is that it has a custom Android build and and i cannot view the device on its screen, however thr computer reads it.
Much help needed!

I have never heard of the device that you are using, after doing a quick google search it seems that you should probably contact a business called the keefe group. They are the distributors and provide support for that proprietary device.
https://www.keefegroup.com/home/contact-us-105
Here is the User manual: https://fccid.io/2AHUC-EDGEMINI-AA/User-Manual/User-manual-3073167
If all you have is the circuit board , then most likely your chances are recovering encrypted data are not good at all.
Ideally, you would need to boot into the system and enter developer options, turn on USB debugging, allow an external device MTC connection etc., which allows you to connect to your PC.
On the other hand, its an older Operating system, with less secure software. Perhaps, for a technicians easy access the steps I listed above have already been setup. If so, try downloading the USB driver for that device, and then reboot your PC. If the issue is a driver issue, you should now have access to the internal storage and will be able to copy over your files, by connecting the board to your desktop, using the usb power cable. If the PC reads the device, you should be able to see the internal storage by going to this PC, and it would be under device and drives.
Are you sure that your files are not backed up to a server that you can remotely access? Worst case, I would look into that option.
Good luck.
