I've got the LG P970 phone running on Gingerbread with a broken screen. By broken screen i mean that screen displays nothing - it's lighten up, all black with color lines but it's touch sensitive (i believe). I've got important data on it and I want to get it back. Unfortunately USB debugging mode is disabled on the phone so adb devices command on linux shows empty dialog.
So here comes my question: is there any possibility to remotely turn on usb debugging mode on android device?
This is how I solved this problem (on a Samsung Galaxy S4):
This assumes that the phone's screen does not display anything, but the touch input still works.
Figure out how to take a screenshot on your phone without using the UI. On the Galaxy S4, you can use hardware buttons to do this.
Unlock your phone's lock screen, and connect it to a computer.
Open the phone in a file manager.
Find the location where the phone stores screenshots.
Take a screenshot on the phone. Look at the updated screenshot.
By doing this, you can perform an action on Android, take a screenshot, and see what screen comes up. After doing this awhile, you should be able to find the USB Debugging menu.
Simple, use a new phone say an S4 to your cracked broken S4 and get to the video port (several youtube videos on this) hook the new screen to the old phone and now you have access to debug set usb or transfer all the files its just as simple as plugging in a working screen!

I really hope somebody can help me with this.
I have xperia z5 premium, power button stopped working a month ago or something, but the phone was working perfectly fine. Of course, I made a mistake and did not charge it in time and it turned off. Now I can't get it to turn back on because the button is not working.
I explored all my options and I realized I can do fastboot reboot through fastboot and adb. However, I can't seem to get my phone to go into fastboot mode.
I hold volume up button (which I know for a fact is working), I plugin usb, and instead of getting that blue led light everybody keeps talking about, I just get a red led and then a green one after the sony logo that signals the phone is charging.
I installed ADB and xperia z5 premium drivers and I still can't get it to work. When I type fastboot reboot it says when I try adb reboot or adb reboot bootloader it says "error: device not found".
I've also installed xperia companion app and when I plugin my phone it shows a screen where it says: "Your device is locked
Unlock require
Unlock the device using password or fingerpint if needed
Allow data access
On your device, select the option to allow data access"
I've tried doing the same thing with adb on two different pcs, always get the same result. Phone just gets to charging screen and keeps charging instead of going into any mode.
I also tried holding volume down button and plugging in usb which is supposed to be recovery mode or something, but that doesnt work either, I also get charging screen. And I'm 100% sure both my volume up and volume down buttons are working.
What am I doing wrong?
P.S - Debugging mode is not on, im 100% sure since i never turned it on.
Somebody please help!
Thanks!
try downloading the sony xperia flashtool and boot your device in fastboot mode by holding down the volume down button and inserting the usb cable a blue light should appear, open up the flash tool and wait for the device to be detected if not detected, goto c drive then inside the flashtool folder there should be a folder named drivers, open it up then install the drivers for your device. back to the flashtool... when your device is detected, click on the lightning bolt icon and select fast boot mode, then you should see a window pop up and click reboot device into system.
hope this solves your problem
I was trying to enable USB debugging option on my Samsung Galaxy J1 Ace (SM-J110H) handset. As you already know that the screen is black/dead but except that the cellphone is working just fine. Somehow I managed to enable the USB debugging option by using an OTG cable and a USB keyboard(and off-course a lot of screenshots). But still unable to authorize USB debugging for my pc as I'm not able to click always allow from this computer.
So how do I allow/ authorize USB debugging from my pc? TIA
Ι would write it here as a comment, because answer is not based on facts, however on black screens I try to remember the basic buttons and can use some of my phones even blindfolded.
However when I was having a similar problem, I used a tool called ADB that made it possible to access some of my Lenovo A390's shell features via Windows CMD and managed to turn on USB-Debugging and even download some backup files from a password-holder app I used in that time.

There was also a stack exchange topic that helped me run through the process.

Hope that helped.
Have two phones. The one with the dead screen and a working one. Download any app that can mirror an Android to another. Use the mouse to download it. Install it in the two phones. You can download apps like airdoid. Create account on the good phone, then login into the same account on both phones. U will be able to control the other phone with the working phone so that you accept the debugging prompt when it appears
Samsung J3 Pro -Mobile screen is damaged and does not show anything, however its touch is working and I can receive calls etc.
I have tried Vysor and MyPhoneExplorer to view the mobile screen on my laptop. but it ask allow usb debugging. However my usb-debugging is also enabled.
Note: I have setting saved on one of my machine. I can access and view display on Vysor and change the setting on that PC. when I use another Laptop it ask for
allowing prompt option for usb-debugging. How to do on that machine.
Touch on these parts of the screen to do this.
trying to understand how things works,
From reading Android site, I know that utilize Secondary display & Presentation
But upon connecting Android device to laptop, how should I make it a USB appear to part of selection.
Is there anyway I can utilize browser like chrome to display the screen from Andriod device?
I notice Vysor able to do this, how is the big picture works?
thanks
I'm using Eclipse+ADT on Mac OS. I have a Nexus 5 connected via USB, but it does not show up in the Android Device Chooser when I run my app from Eclipse. Actually, it did show up once, and I could deploy my app to the phone, but then it just disappeared from the Android Device Chooser.
The really weird thing is that the device is listed when I run
adb devices
on the terminal. I even get the debug messages from the phone in Eclipse's LogCat, so it clearly is connected and recognized – but it still doesn't show up in the Device Chooser. I have tried all the solutions proposed here (rebooting the phone, turning debug mode on and off, restarting adb, restarting Eclipse, etc.) – to no effect.
Any ideas?
I had the same problem. I couldn't see my Nexus 4 in the Device Chooser list even though I could see it in the DDMS. I found out it is just hidden from view. Click the device chooser list and scroll up with your mouse wheel. The device should now be visible in the list.
Eerily similar to what I just spent the last hour figuring out. OS X, Nexus 5, shows up in adb devices, tried everything under the sun.
In my case, it turned out that even though the device wasn't listed, I was able to press the OK button and it launched just fine. (seen below)
I'm not sure if it also helped, but before I stumbled upon that solution, I edited my Launch config options to change from "Always prompt to pick device" to "Launch on all compatible devices/AVS'S" and selected the "Active Devices" options. I ran that and it worked! I expected the device to start showing up in the above menu afterwards, but it didn't. Then I realized it didn't matter and I could hit OK and it would build. Go figure.
The solution of blazeline worked for me but it was a little bit tricky to scroll up to make appear the device.
Another way to do it and to make appear the device more clearly is to disconnect your device when the Device Chooser List is opened and to reconnect it. It will clearly appear now in the device chooser list.
Eclipse is really sometimes strange...
My case was same as mentioned here and obviously i did all tricks with no success but solution was very logic:
device i was missing in pickup list had lower API then allow by AndroidManifest.xml
