Can You Enable USB Debugging On a S7 with a non working screen? - Samsung Galaxy S7 Questions and Answers

My gf broke her galaxy s7 by dropping it. The screen is totally black, but the phone starts up and what not ( can hear the noises). I had the insurance through AT&T so the replacement phone was only $112. Anyways is there anyway to enable USB debugging on the phone from the PC. I have downloaded minimal Adb and fast boot, but when I open up the prompt and typed in "ADB shell." It said no devices or emulators found. The phone is showing up as a G930A on my PC, but when I goto access it everything is blank. I have tried Dr fone (does not support S7) and smart switch. Is there anyway to get into this phone. I am trying to make sure I have all her info saved before shipping the phone back.

I know of no way to enable USB debugging without a working screen. If the phone has a passcode, this will reduce the likelihood of being able to enable the debug option.

There is no passcode, but based on your info and what I have been finding searching around no one seems to think its really possible.
Thanks

[Completed] Screen inaccessible(no display) usb debug disabled cmd help

Nexus 5 running 5.1 stock
I had recently and sadly had an accident with my phone where the screen is completely useless. Shattered is a harsh word, but it's sitting in that condition. It does however still turn on. There are parts of the screen that display, but for some odd reason, its completely mirrored and upside down.
I have Android tools and drivers installed. And knowing something like this might happen, I had USB debugging enabled. BUT, for even stranger reasons, I'm guessing it's disabled because through cmd on platform-tools, it says it's unauthorized. Though the little window of display my phone pushes, I'm guessing I'm getting a dialog asking for USB debugging to be enabled. I'm not too sure how I got to this window, but it randomly appears on restarts of the device, and half the time, it just restarts normally like any restart.
I was wondering if there was a way I can push a command line using cmd on my PC to accept or continue from the dialog box that I literally can't see.
I looked far and wide on Google and this beloved website, but am having a hard time finding a solution.
The device is bootload unlocked, running stock on Lollipop.
I do not know if rooting and installing TWP will affect my data, as it is the only thing I really don't want to lose. I wish to keep stock as I am completely fine with it and I have tried custom Roms, but I still wish to continue using stock.
I'm not too familiar with some words used in explanations on this site, so please respond as if I'm 7 years old :silly:
My initial goal was to (while having usb debug enabled) fastboot (i think i'm using the right term) Mobizen, then mirror the screen on my pc, and control the device to upload everything to my cloud storage.

Help retrieving pictures - Broken LCD

Hello,
I've got a GS3 that I need to get pictures off of. The digitizer and lcd are both broken. The phone turns on but the screen is black. There's a lock code on the phone so I have to unlock it to put it in media mode, which is the problem. The phone is not rooted and it's got stock ROM. I've been searching for two days now for a way to get the pictures off of this phone. There's solutions out there that involve connecting a mouse and entering the unlock code but that won't work as the screen will not turn on. Tried adb but the device is not detected. Any help would be GREATLY apprecitated.
Got it figured out. Hooked up a keyboard to the phone (as opposed to mouse as other forums suggested) and was able to type in the unlock code. I had kies running so as soon as I typed the unlock code and hit enter I unplugged the keyboard and plugged the phone into my computer and I was able to transfer everything to my pc via kies.
Glad to see you posted your solution. That will go a long way towards helping others.

How to recover data black/broken screen S7

Hello, few days ago my phone's screen stopped working. So I cannot access my phone since its locked behind pattern lock. I tried with ADB but I keep getting ADB Device Unauthorized and I don't know how to fix that.
As far as I know I believe USB Debugging is enabled. I tried a lot of ways with useless one click apps, mirror screen apps but nothing work as I need to unlock phone to give permission to the computer to communicate with the phone, but I cannot do that since the device screen doesn't work and I cannot see anything. I have an OTG cable and tried to unlock with mouse but its easier said than done.
Can someone give me any tutorials.
It requires a couple of your phones internal software switches to be set in order to access your phone via the USB interface. If you have not already set these switches before the screen got broken you may be out of luck.

S7 930U (Snapdragon) ADB connection issues

So I had a broken USB port for a while, but since I want to pull data off my phone (including, if possible, the apps that I needed 2FA to enable like WhatsApp and so on, since I'm currently in Europe for the next 6-12 months and AT&T prepaid doesn't allow me to receive text messages or phone calls).
I bought a replacement daughterboard for the USB connector, and pulled the back of the phone off, removed the old USB connection board, and replaced it with this one. However, I've got some weird problems and I'm not sure if its hardware or software related.
When plugging the phone into USB, there's no indication on the telephone that the phone is charging, there's no indication that the phone has some connection to the computer, the computer doesn't display anything about the phone or allow me to access storage, and ADB can't find the device despite trying about 7 different methods and combinations of drivers, ADB programs, etc.
So I'd believe that my new daughterboard is either broken internally or some other issue ... except ODIN works flawlessly, as I got the inital step of loading the combo firmware to work without issue. (linked here: https://forum.xda-developers.com/t/root_method_rev_b-11_bootloader_using_combo_firmware.4374741/). But I can't get safestrap to work, because it relies on ADB, and ADB still doesn't have any way to connect to the device.
When I start the phone in download mode, I'm able to pull up a device with the Hardware ID USB\VID_04E8&PID_685D&REV_0100, but ADB doesn't recognize it. When I start the phone in any other method, the device doesn't register in device manager. It's a similar story when I tried reaching the phone with ADB from my linux desktop, as "something" exists in download mode, but adb has no ability to actually see the device or make a connection.
As far as avoiding obvious pitfalls, I enabled development mode / USB debugging / OEM unlock in the stock firmware I was running before, and also enabled dev mod/usb debug in the flashed firmware from that page.
It's quite possible that flashing the Combination firmware already wiped my data, as I'm not sure if it does it or not (after scouring the internet, it's pretty much the only option to get root with the B/11 bootloader so it was worth a shot), but ultimately I'd like to try and resolve this ADB issue so that I can actually finish the steps and see if it will work or not.
I just don't know what to troubleshoot next to try and get ADB to work.
To add on to this, I tried reaching out to AT&T to see if I can use my S8+ (VoLTE and all that jazz capable) to receive text messages while abroad here, but they won't let me use the phone even though I'm already abroad, since if it's not compatible with their network in the US it won't be compatible with their roaming network abroad. So I really do have to do the ole root trick.

How do I enable adb debugging and otg with a black screen and no otg cable?

Hello, I just broke the screen of my OnePlus8t Verizon network unlocked phone. The computer I previously linked 8t with also has a broken screen. ... Rains it ..... My Phoe has some important information in docs and screenshots I need to get. I just turned off ADB debugging thinking "Oh I don't need that just yet" the very morning I broke the LCD. Good news, I can still answer it. I already have adb.exe except in ADB shell it shows as unauthorized. I need those files like yesterday. I have an otg/ADB flash drive, but I still can not connect to retrieve files. I can see my phone when I directly connect to comp without the flash drive, however, I can not access it. I have tried to put the phone into recovery, but I have no way to enter the pin as I have tried to guess where it is. How can I receive the data I need from my phone?
Thank You.
P.S. I have little knowledge and only learn what I need to know for whatever project, in other words, I can not code and I barely speak dos.
Is the touch screen still working then?
If it's showing "unauthorized" you can try to plug it into your desktop and then hit the "authorize" button on the popup that you can't see.
Here is where ok is on a different phone. It's somewhere near there on yours.

I have tried that. The finger print unlock screen only works ⅔ of the time. I have no way of knowing if it's unlocked. I keep my touch sounds silent. I keep trying to find where it might be. I have tried to slide as if answering a call. Is there a way to force the USB settings for media transfer? Maybe through Google? If any platform knows it's my phone is Google. I can go to the play store and push apps onto it. Unfortunately the two adb drivers I have installed on my Android didnt work.
Oh, actually, you've got it easier! The OnePlus 8t supports HDMI over USB Type C.
https://forum.xda-developers.com/t/does-one-plus-8t-have-video-out-through-usb-c.4465629/
Buy an adapter and hook up an HDMI monitor/TV.
Or just use a new monitor on the computer that is already authorized.
Is there any other way. Right now it is not with in the budget to afford any extras even with the price tag of $20. I am hoping there is a way within an adb shell to force turn on the adb debugging. I have developer options enabled. I would just rewrite the documents, except some of those items I need include the text messaging history. If I can't force the adb, can I remotely back up the phone? Is there a trustworthy app for that? I do have quick settings installed and if my memory is correct, I believe I have sideline installed even.
