[Q] Controlling Nexus 4 on the PC after breaking screen, possible?

Hey guys,
Haven't been here for a while. Okay, so I have a bit of a dilemma and every solution I've found requires something I just can't do. Here's the situation: my screen is broken, it has a lock screen, not in developer's mode, not unlocked.
This means:
I won't be able to transfer my files over, as I have to get past the lock screen
I can only install applications from Play store on my computer, but can't launch them
No use for any method that requires phone to be rooted
Can't even activate any USB options to transfer files some other way
Still need to be able to control it to create backups and such of important SMS messages, get files off
Does anyone have any suggestions at all? I don't want to have to resort to replacing the screen, as that'll end up costing me enough time and money where it's more cost-effective to purchase a new phone; however, I really need what's on my phone as soon as possible. Thanks in advance.

I think I have a solution for you: http://forum.xda-developers.com/showthread.php?t=2177440 Specifically, you'll want to read this post:

So typically, just as I fill my claim to repair my nexus my wife drops her, smashing the screen even more than I did so she has absolutely no use of her screen. I went through the process again and though I'd post it in a more simple fashion.
1. Reset Nexus into recovery mode (power & volume down)
2. Connect to PC via USB. Install the USB driver from the SDK so that it appears as an ADB device
3. Fire up the updated toolkit. You should see the nexus as a fast boot device
4. Unlock bootloader
5. Using option 10 on the toolkit load up CWM on the phone. This gives you ADB access so can you pull files off the device via ADB although I could access the SD card through programs like Droid explorer.
6. If you want to carry on further and get into Android properly, you'll need to wipe the cache from within CWM
7. Reboot and hold down the volume key to get back into recovery
8. In the toolkit select root options (option 4) and load temporary image (6) If it hangs on the google or nexus logo you've not wiped the cache.
9. With this second phone I couldn't access it through droid explorer as it was popping up as an MTP device but I could pull the files via command prompt or through the toolkit
10. If you have any use of the touchscreen at all you can run the following command which will then mean that any touch will unlock the device
adb shell rm /data/system/gesture.key​11. You can activate bluetooth via adb if you have a mouse or keyboard available but you will need to be able to press okay on the screen
12. Any changes you make in the unstable android image such as lockscreen, bluetooth, enabling debugging, etc will remain in place when you restart the device.
13. You can relock the bootloader if you wish via the toolkit. You just need to be in recovery mode first.
Hope this simplifies the process

In the future, always enable USB debugging in case of incidents like this. You can then use ADB commands to do a heck of a lot of things. Of course, it does make your phone data vulnerable if it gets stolen, but I'm willing to take the risk, plus 10 wrong PIN tries = reset anyway.

where did you get the screen for $79???

hi, what does this mean?
2. Install the USB driver from the SDK so that it appears as an ADB device

1. It means that if you have the SDK Manager installed on your computer, somewhere between the last packages at the bottom of the list, you'll see "android drivers" (or something similar). With those drivers, your device will show up in "Device manager"(the Windows' one) as an adb device.
2. But if you don't want to get the SDK Manager and be quicker, you can download only those drivers, directly from the "Google developers" page and install them manually by going to "Device manager", right clicking on the Nexus 4 (it will appear with a yellow triangle on it, maybe), then "Update driver", "...BROWSE computer...", then click again on "Browse", then go to where the drivers have been downloaded and select the entire folder by highlighting it and clicking ok (or something). The folder with the driver would look like this "latest_usb_driver_windows" and inside you'll see another folder called "usb_drivers". That's what you need to select and install.
So that's what you need to do to make your phone appear as an adb device in "Device manager". And, of course, adb let's you do a lot of stuff to your phone through your computer, but probably you already knew that.

[Q] Nexus 4 screen cracked, need someone fluent with ADB to help

So that's it, my Nexus 4's front glass is broken to where I can only use half the screen. I want to unlock this thing and use ShareKM (Lets me use my mouse and keyboard from my computer on my phone) and Airdroid too I guess. The reason I need help is I can't type in my PIN to unlock the phone and even if I could, I doubt I'd be able to navigate to either ShareKM or Airdroid to start them up. Is there any adb command or otherwise to forward the pin to my phone through usb and then a command to start up the apps? I just wanna be able to use it and get some stuff off before I send it in to be repaired. Thanks in advance.

Not sure about unlocking the pin through adb, but you could use adb pull to copy the files that you need off the phone.

Maybe try this tool
This will only work if your phone is rooted and I hope you enabled usb debugging and unknown sources, otherwise I don't know what to do...
If you will have passed the lockscreen, you should be able to install ShareKM and Airdroid via ADB (if you have the .apk). But I don't know if it's possible to activate ShareKM without using the touchscreen.
But just to get your data off your phone, simply use
Code:
adb pull /sdcard/
then you have a backup of your music/photos/etc

Use adb while in recovery mode. Twrp supports that. Pull the sdcard like the above post suggests.

ADB not working

Hi guys...
Yesterday my new PH-1 arrived and today I wanted to use ADB with the app "custom navigation bar". My problem is: i can`t get it to work... I´ve used adb several times with different phones, but with the PH-1 it can´t connect with my Windows 10 computer. Is it possible that I can´t get it to work because Ì´m using a different USB-C cable (took 3 different from Xiaomi another manufacturer)?
How do get it to work? Everytime I connect the phone with the computer, I get the message USB debugging is on and I use MTP to work, but the phone doesn`t show the RSA key fingerprint. Any suggestions?

Mines wouldn't connect using the usbc cable it came with I had to use a regular usb to usbc cable for it to work

See your device manager. To see if you are seeing "Mata". You have to download the google usb driver and update it from there
I have S8 from my previous computer but i need to re install the driver again

https://www.youtube.com/watch?v=LbAq6d2Du0U
You can also try this tuturial hope that it is working for you.

Try this > Download and install the essential usb driver > go to device manager and update the driver. Choose the option where you can change the source and select the driver in the list > go to the Essential Folder in Program Files and choose the file named "essentialadb.inf" for your pc. That should work
It's and old thread but if there is someone new to this...

My essential wouldnt work with the previous ADB i had installed that had worked fine with all my other devices.
I installed https://forum.xda-developers.com/showthread.php?t=2317790 and worked just fine. Make sure your device isnt connected as anything other than charging. The previous ADB i was using didnt acknowledge my device but on first try with Minimal i was prompted on my phone right away

I had the same problem when attempting to flash my ph-1, when trying to use the cable that came with the device. I used a standard USB-A to USB-C cable and everything worked just fine. I noticed on the 8.1 update notes for side loading that the team indicates that the cable that comes with the phone is "Primarily" designed for charging and not data transfer. So I'm guessing that it is of lower quality and doesn't handle the transfer speeds.

Hold either volume button while connecting cable from phone to pc, it will detect automatically. It may work.

Recover with dead screen

Hey guys,I hope that all the awesome people here can help me to solve a huge Problem.
My GF had a Galaxy S5 Neo,she thought it would be a great idea to drop it directly on the screen so it broke and won't show anything anymore.
No we need to backup some important files from that device.
Gladly I was able to remove the lockscreen protection with her Samsung Account,but still not able to do more.
The device is on the latest official update,not rooted and no USB debugging enabled.
So I tried to get in recovery and use adb,witch will work every now and than,but I found out that the adb in stock recovery is limited,so now way to do anything there.
If I had enabled USB debugging,I could easily use visor to controll the device.
If I connect it via USB to my PC,it shows up,but as an empty device.
And I can't change the USB mode,because screen is completely dead.
Can I change the USB mode without the screen?
Can I enable USB debugging without the screen?
If I could change at least the USB mode,that could help out at least a little.
Long story short,I need an way to backup file from that thing.
If there is a solution for this,you guys would really help me out.

Hey, i have similar problem, i cant unlock the phone so i have empty device at computer, i was wondering if you have any news on it

You Need OTG
Assuming
- you have stock 6.0.1 and
- you have enabled Developer options,
Here is an easy way:
1. Wait for boot to complete.
2. Once you feel like you're at the Touchwiz home screen, attach a keyboard to your S5 Neo.
3. On your keyboard, press Windows + N (Quick Settings tray).
4. Press Tab twice and Enter (Settings).
5. Keep on pressing Down Arrow for 5 sec.
6. Up Arrow one time and Enter (Developer options).
*** You can now (A) enable USB debugging and/or (B) change USB configuaration to MTP ***
7(A). Down Arrow * 7 times and Enter (USB debugging).
7(B). Down Arrow * 22 and Enter (USB configuration).
8(A). Right Arrow and Enter to allow USB debugging (OK).
8(B). Press Down Arrow and Enter (MTP)
9(A). Connect your phone to your PC *** You MUST keep your keyboard connected ***
9(B). Connect your phone to your PC.
10(A). On your computer, run "cmd" and type "adb devices" to authorize. *** You will see "unauthorized" from your cmd window ****
10(B). On your computer, you will see your device connected.
11(A). On your keyboard, press Tab * 3 and Enter (OK).
12(A). On your computer, type "adb devices" again to see if USB debugging works properly.
Note that this may or may not work for you depending on your firmware/settings.

Broken /Black display - How to transfer Data to my PC (MTP Mode)

Hello everyone,
i looked up similar but havent found a solution to my problem, so i hope you can help me on this one.
My OP 5 fell down, resulting in a broken screen. It is still fully functionally but completely black and i can access the phone via fingerprint as long as its still on. I need to get in MTP Mode to be able to transfer all the Media (e.g. the last year of my kids growing up in pictures)
Dev Mode is activated, so after i plug in my USB Cable to connect it to my PC i think i emember that i can access the selection (Charging/ MTP etc.) over the dropdown menue.
I just have to find the right spot to click.
Can anyone of you maybe screenshot the scenario?
1. After the USB is connected and the debugging window appears
2. The screen when you can select the connection mode?
I tried to use the Program "apowermirror" as well but i cant see where i have to click on the Screen when it says " allow usb debugging" when it tries to connect via USB. So a screenshot of this could work as well.
Additional Info: the bootloader is unlocked and i have TWRP, so maybe there is also a way ?! im a total noob regarding this...
Thank you very much in advance for any help on this.

Maybe in twrp you can with adb command, install adb on your computer and search (google) about the command "adb pull" or maybe just reboot twrp (power off and power with vol down) you can access storage. Have you some security? Pin or pattern?

hi, try the program through MyPhoneExplorer, you can via Wi fi
