I dropped my N4 on the ground this past weekend and it now has both a shattered front and back glass. The digitizer does not work so I can't use the touchscreen at all.
Here's what I can share about the status of the phone:
It is still on, I can see the screen, and is fully charged receiving messages.
The power button and two volume buttons work.
The phone's storage is encrypted with the stock android encryption.
I have a 4-digit PIN enabled on the lock screen.
The phone did not have USB debugging enabled when this occurred.
I've tried to mount it to a computer to get the files, but nothing shows up as I believe I need to unlock it with the PIN before it will mount.
I can install apps remotely from the Play store.
I have the Sophos mobile app installed and configured but I don't believe there are any commands to UNLOCK the device, only to lock it and wipe it.
Honestly, I just want my data off of the phone and would rather not replace the screen and continue using it. I love the phone but it is way too fragile. Is there any way to transfer my data? I looked into connecting a mouse to the usb and using that to enter the PIN, but the N4 does not support mice. Since USB debugging was not turned on, I can't connect via ADB. Is there some sort of app I can remotely install from the play store to turn on USB debugging? Is there some sort of app I can remotely install to remotely unlock the device with my 4-digit PIN? If I let it die and then try to boot into recovery, will ADB work then? If so, how would I get the data off of the device if it is encrypted? Any guidance would be greatly appreciated.
Thanks in advance!
Is it running a custom recovery?
If yes, just go into recovery and do a nandroid, boot back into android and copy the backup.
If no, there's a thread somewhere with instructions on how to unlock your bootloader WITHOUT wiping your phone.
Unfortunately this is the only android phone I've ever owned that I haven't touched and left completely stock... No custom recovery, no custom ROM. I'll try to look for the instructions on how to unlock the bootloader without wiping the phone, but if I do a nandroid and boot back into android how will I transfer the data? I'd be stuck at the screen where I have to type in my encryption password, and even if I got past that I still can't mount the device in Windows to transfer the data?
Anyone?

The only way I can think is flash an advanced version of cwm (if it doesn't already have one) that has a file manager and make a backup, and copy the recovery to a location on the SD. Then mount USB storage and copy everything over.
Edit: actually, you could mount USB storage in cwm to copy files over, then make a backup through adb on to your computer, there's some tutorials on how to do that

do you have adb installed? cant you copy the files in bootloader mode to the computer? havent tried yet, and im on my work laptop right now, cant try it.

as far as I know no. In bootloader mode is only fastboot, not adb

what i dont understand is how you cannot connect the phone with mtp... that should work without debugging.
EDIT: sorry, youre right, when the device is encrypted, you have to unlock it before mounting.
looks like you made pretty damn sure there is no way for you (or anyone else) to get access to the data on your device :/
although i dont know about unlocking without wiping. maybe that could work.

Google search a program called Motorobo; equivalent to what service providers use.

Hi all,
I unfortunately broke my Nexus 4 some days ago. The screen is still working fine, but the touchscreen is not working at all. I am using AOKP (jb-mr2, android 4.3) and I have ClockworkMod Recovery 6.0.2.3.
With adb on recovery, I managed to pull back all the content of the sdcard. But I would also like to save all the apps and apps data. I tried, on recovery to use "adb backup –apk –shared –all –f /backup/mybackup.ab" but I am not authorised (error: device unauthorized. Please check the confirmation dialog on your device.). I also tried after normally booting but I can't connect with adb:
List of devices attached
0200eb4d4b0e6615 unauthorized
My screen is locked with a password, the usb debugging is not activated. Does someone know a way to activate usb debuuging, so that I can connect with adb to allow the backup of my apps?
Thanks all,,
Jean.
Hi all,
I greatly need your help or some advice. I searched for more than 6h yesterday and Im surprised I couldnt find a solution to my problem.
Typical stuff : I broke the screen of my Nexus 4, that is completely stock 5.0.1. The phone is unrooted, bootloader is locked and obviously USB Debugging is disabled.
I need to backup some data from my phone : pictures, notes and if possible my contacts.
When I connect my phone via USB to my PC, I cant browse my files since my screen is locked. My screen is not responding at all, so no way I can unlock it. Only thing I can do is install new applications on my phone, but no way to launch them since I'd need to unlock my screen again.
I have installed adb and fastboot in order to try and use Android Screen Control, but I dont have USB Debugging enabled.
So I read that I could sideload a kernel that has USB Debugging enabled by default.
I got into Recovery Mode, and tried sideloading a zip file containing a Kernel found on the forum, but I always get an error saying the footer is wrong and the signature of the file didnt pass verification. I guess I can only sideload OTA updates ?
I tried fastbooting CWM recovery, that also didnt work.
adb devices command lists my 'recovery' device.
At this stage, all I need is to either be able to unlock my phone so I can access my files via USB (i tried few apps without success), or to enable USB debugging so I can connection using sideload, use Android Screen Control, reset the pattern lock, and backup my phone.
Also, USB OTG isnt enabled by default on Nexus 4, so that's another dead-end
So what are my options ? Where could I find a kernel that has USB Debug enabled, and how can I sideload it considering phone is not rooted, and bootloader is locked (unlocking it and whipping data defies the purpose).
THANK YOU for any advice!
There is nothing you can do with a locked bootloader and no custom recovery. Sorry man, but you're not going to be able to access your data.

I've exactly the same problem, but my bootloader is unlocked and I'm rooted.
I'm also on a Nexus 4 with 5.0.1 and I'm trying to get control over my device from my Windows PC. But I don't know which kernel to use and how (yet) to enable USB debugging.
Help is appreciated.

All you need is a custom recovery to boot into to access your files. If you don't have one, download the latest version of twrp from here. http://techerrata.com/browse/twrp2/mako
Then flash that using fastboot. If you need help let us know.

Hmm, "error: cannot load 'open recovery-twrp-2.3.2.3-mako'.
Sure usb-debugging doesn't have to be enabled?

You have an ancient version of twrp. Install the latest. I'm positive you don't need usb debugging enabled.

Yes, you're so right! I also missed .img in the command
But what kernel would you recommend me to use so I have usb-debugging I can have usb-debugging enabled?
I am in almost completely the same situation! My N4 fell yesterday and shattered at the bottom right hand corner. No the touch screen doesn't work and there are sections of the screen that are black. However, I have...
root
cwm recovery
stock 5.0.1 kernel
windows 7
adb not working
fastboot working
usb debugging disabled
a need for usb debugging to become enabled.
I would like a kernel with usb debugging enabled and instructions on how to install it. Or if you have another fix, instructions on that.
So as the title says, I recently lost control of my phone and in a panic full wiped everything. I figured this wouldn't be such a big problem as the hardware was fine, however, I'm now realizing that without developer mode and usb debugging enabled I can't do ANYTHING. I've tried to reflash stock via adb but the device isn't recognized, likely for the above reasons. Under normal circumstances I would just plug my phone into my computer and use MTP to move a rom over, however since the default mode is USB charging and I don't have have an OS installed, it seems I can't change that.
I've been told that it's essentially impossible to brick a nexus nowadays, but I feel like I somehow managed and for the silliest reasons. . Someone please help.
Edit: I should mention that I still have access to TWRP somehow.

While in TWRP, use ADB Sideload and install the latest OTA zip from Google:
https://developers.google.com/android/nexus/images?hl=en
Edit: How did you reflash stock? Because you should be able to do the above, ADB push, or drag and drop via TWRP. You may have to mount the file system before doing so.

USB OTG pre-populated with a ROM maybe?
Hi all,
My mother's Redmi Note 7 have a broken screen and it seem to be somewhere in the motherboard rather than the screen itself (tried replacing the screen with a new one and the issue is still there).
There's TWRP on it, the phone seem to boot (I can see it on my PC, I just can't enable USB file transfer) and ADB seem to launch but get me an unauthorized error message. I'm trying to get it back (pull /sdcard/ for starter) and I know the decrypt password for /data/.
Is there a way to make it work through ADB despite the unauthorized message (already cleaned the key in .android and restarted)? Or can I remote in TWRP in some way? Last option I see is an OTG adapter for screen + mouse but the one I have from the PinePhone doesn't seem compatible so I don't know if other brand would work?
Thanks in advance!
