Nexus 4 - Broken screen, no touch, need to unlock - Nexus 4 Q&A, Help & Troubleshooting

Dropped phone, cracked screen, screen works but is unresponsive to touch.
Problem: Need to unlock to access data. This seems to be a common problem but I've been reading the forums and still cannot find a solution
Status:
- USB debugging disabled (presumably)
- No OTG support
- Not rooted
- ADB, running adb devices command shows no device
- Booting to android screen shows Secure boot: enabled, Lock state: unlocked (not sure what this means)
I've tried Vysor and k.janku1's tool, both don't work as presumably the USB debugging is disabled.
Is there any way to enable USB debugging? Or is there any way to connect to ADB? Or any way to flash CWM without ADB?
Any help would be greatly appreciated!!

What data you want to access? May be you need to see if you can boot in to fastboot mode, flash a recovery and then take it from there.
If you are able to do that then you can connect your phone to PC and access it as an USB stick.

Thank you!!! I have flashed the CWM recovery and can access it on my phone. Where should i go from there? I have tried 'mount USB storage' but the phone is not being recognized on the computer still, I cannot see the storage. I am trying to access mainly contacts and photos. Thanks again!

Your contacts should be synced to your google account. Get them from there.
I do not use CWM as it is not supported these days (although it was my favorite recovery back then). So can't help you. As @[email protected] suggested, flash TWRP.

Thank you both, TWRP worked and I could connect it as USB storage to my computer!
Another question is, would it be possible to enable USB debugging through adb/CWM/TWRP? So I can use those tools to control my phone via computer.

No, that's not possible as far as I know. If I were you, I would have flashed a custom ROM which has USB debugging enabled (Like NitrogenOS)
Don't know how can you flash that without touch. Check if some connector like this allows you to use your mouse with the phone.

[Q] Turn on USB debugging with broken screen & digitiser

I have a broken screen and digitiser - I can see nothing at all on the screen and it does not recognise any touch movements.
The phone does appear to turn on and is recognised by my computer.
I want to retrieve all my data - photos, videos etc - from the internal SD card.
Unfortunately I did not have USB debugging enabled when the screen broke.
Is there a solution to achieve thiis?

Connect with usb and copy your files to the pc You don`t need usb for that.
Thanks for your reply Gee but that was, oddly enough, the first thing I tried.
The computer recognises the device as a portable media player and there are no files found in the device.

Maybe my original post wasn't too clear.
I need to retrieve all my data from the S4, and the conventional method of plugging in to my computer via USB does not recognise any data. Would I possibly have to select to mount the card to view? Either way, this is not an option due to the broken screen.
My next thought was to use ADB to transfer over all the content of the internal SD card, however, my S4 is not recognised using ADB (I assume as USB debugging was not enabled when my phone broke?)
So, is it possible to enable USB debugging without use of the screen on this device?

do you have custom recovery on your phone??
No, the phone is entirely stock.
I'm still holding out hope that someone has seen this happen before and knows of a solution for me to retrieve my data?
Can anyone help me with this?

Can I flash customer recovery, though, as I can't see my screen?
You could install ClockworkMod Recovery and use ADB to retrieve your data while it's in recovery. You can put your phone in download mode by pressing and holding Volume Down, Home and Power buttons till it vibrates. Then press Volume Up to confirm that you want to enter download mode. You should then be able to use Odin to install ClockworkMod Recovery.

you can boot in download mode and flash it without screen. see if odin recognize it
In my opinion if u could turn on usb debugging that would not bring back your lost data. Not really sure though. You could do that by connecting a micro usb to hdmi cable to your tv and then i guess you could use the phone there, not sure if the touchscreen would work though but worth a try..

Thanks - I have flashed CWM via Odin successfully.
I have installed ADB but my device does not get recognised as an ADB device - have I missed something?

be sure that you boot in custom recovery, connect your phone, open cmd in adb folder (shift + right click) and type (no need to enable usb debug):
Code:
adb devices
you must see the serial number (in recovery mode)
Code:
adb pull /sdcard/
use attached adb folder

Because I can't see the phone I'm not sure the state it's in.
Is it just Volume-up + Home + Power to access customer recovery?
I can now see the device in ADB.
When I run the adb pull /sdcard/ command I get an
error: device unauthorised. Please check the confirmation dialog on your device.

hmmm do you read "recovery" in command line after the serial number?
there is a dialog box showed on your broken screen, try to tap on, maybe you will hit confirmation
EDIT: your digitizer is broken!......no way to recognize touch.....

Use Nexus With Cracked Screen

Current problems:
Developer options not enabled and USB debugging mode not on.
Anyone know how to solve this?
What are you trying to do? You can flash a custom recovery from fastboot and use adb in that, none of that requires a working digitizer.

The problem lies with the phone not being detected by the computer because USB debugging isn't enabled.

Well I'm trying to install AirDroid so I can use my phone without using the digitizer since it's broken.
I plug it into the computer and try to push adb commands but can't.
I did find another way to work it by booting into Recovery which allows me to push in commands but not sure of what to do from here.
From recovery. 'adb install airdroid.apk' (or whatever your file is called)

How would I actually start up the App though when I'm back on?
Edit:
Sigh, I'm sooo lost.
Wish I can just use an OTG wire and navigate with my mouse but no, Google has taken that away from me too
Can anyone else help?
You can get applications to start at boot a few ways.

[Urgent help]Broke N4 Screen - Need to backup App Data - Rooted - Debugging Enabled

So as the title suggest, my screen is working but not recognizing touch. Basically useless.
Device is rooted, Usb debugging is enabled but RSA Key is not authorised to this pc.
Stock Lollipop with custom kernel.
Problem 1 -
I am already with CWM recovery. From what I have read from cwm recovery I must be able to get access to adb recovery mode so I can backup my app data from system but the device stills shows "Unauthorized" in recovery mode. I dont know why this is happening?
Problem 2 -
I bought the OTG USB Y Cable thinking I might be able to install a differnet kernel that support otg through external power source but then I read that most kernel require to manually enable the option in settings/tweaker app for OTG SUPPORT. I cannot do this becasue as i said my screen is not working.
Please help me out.
Does your computer recognize the phone in bootloader? If so I would suggest you flash twrp and then try booting to recovery. Then you can check if your computer recognizes it now.

Yes.
Already did that and it did work.
Was able to backup few imp. data.
I just have one more question -
Is there some kernel which support otg in Lollipop without me manually going into settings/tweaker app for kernel and enabling it?
Because I cannot do it manually coz the screen is broken.

Mtp not working in recovery mode

Hello
I am having issue with mtp in recovery mode for twrp
When I enable this. My computer does not see my phone in windows. I get the mtp device with the exclamation point in windows and am not able to see my phone to install anything.
I can only do adb sideload to install my apps. Mtp is fine when I am using it normally on my computer when I am not in recovery for twrp.
For additional information this is also happening when im on windows 10:
USB debugging disabled - MTP working
USB debugging enabled - MTP not recognized

Try this, this work for me. Saved my X727 after encrypted and format Everything.
https://docs.google.com/uc?id=0B9ZMWt4u_wSDVkp3UlMxS1liMUE&export=download
Flash it via Fastboot and re-flash from recovery (install/Image and choose "recovery".) Now you will see your Smartphone like a drive on your PC from recovery.
Hope works for you

Would this wipe my rom and data?
I don't know if this is a hardware or software issue. I was having issues syncing my phone with my computer. The computer kept freezing while I was going through my phone's files on it. But I found that switching my USB-C cable for a better one (a Benson-approved one) fixed the issue instantly.

Select Usb Configuration.

All the time it goes back to "charging". Isn't there a way to get it to MTP permanently?
When i am on TWRP is MTP enabled?

You need to activate the developer options there you find the option to configure that default behavior.

Don't work
Here on OOS 5 I just tried it, switched it in dev options from charging to MTP, connected to my PC and it came up with MTP.
Yes it works for the 1st time. If i try it again, it goes back to charging.. This is very dangerous if i try to install a custom rom which requires format data.. I couldn't transfer files via TWRP. Can someone help?

But this affects only the handling when booted into the OS. Twrp has its own handling... Perhaps you mean to enable USB debugging?
So you mean that when i enter TWRP, MTP auto-enabled? If yes, this is just fine.

Try it, I could access an OTG USB device from TWRP without problems regardless of that setting. You just have to mount it.

Works only the first time, then at the second attempt you get "recharge"
Yes i checked it. On TWRP the MPT is auto-enabled.
