______________________________________________________________________________________
Firstly, I've spent the last three days scouring XDA and some other forums searching for solutions and trying various options.
The screen on my N4 has cracked and I've lost the use of the bottom half of the touchscreen. This means that I can't unlock my phone.
The phone is insured and will be repaired, but there are photos of my son's first birthday on the internal memory that I don't want to lose. I'm concerned that the phone will be factory reset during a repair or I'll receive a replacement. I'm trying to access the internal memory remotely to backup these files before I send the phone off. The problem is that I hadn't enabled USB debugging before the accident. The phone is completely stock including the bootloader.
So I can access via fastboot but not via adb.
Q1: Can I pull file from the internal memory via fastboot
Q2: Can I enable usb debugging via fastboot
Q3: The phone is set to display as an MTP device in windows but as I can't unlock the screen, none of the files are showing. Is there anyway around this?
Q4: Purely via fastboot, can I unlock the bootloader, install CWM so to use ADB within it and then return to a stock bootloader?
I think they're my options. Any answers to the above or alternatives would be appreciated.
All of the other threads regarding this, the users seem to either already have CWM installed or they're looking to perform a factory reset. I did consider resetting the device via the bootloader in order to bypass the screenlock but I understand that on the N4 this wipes the internal memory as well.
Unlocking the device isn't needed to pull the files from it, just plug it in and get what you need from the internal memory

On mine if I plug it in it appears as an MTP device but with no files. I then have to unlock the screen and select USB something-or-other from the notificationss bar, then the files appear in windows.
Strange, mine never needs to be unlocked...I'm using Windows 8 Pro btw but it also works fine in work on Vista Business
Only other thing I can think of is the fact I'm unlocked and running a custom ROM, I've never used my N4 stock. It was on CM within 30 mins of receiving the unit!
So over the last week I've managed to solve my problem. I've seen several other people asking for help with no luck so I'm posting this here in the hope that the search function will bring it up.
Firstly, my phone was completely stock running 4.2.2, unrooted, with the locked stock bootloader. USB Debugging WAS NOT enabled. I had pattern lock enabled when I dropped the phone. The screen cracked and the bottom half of the touchscreen was unresponsive.
The phone was insured, but I wanted to backup photos from the device before sending it off for repair/replacement.
HOW I FIXED IT.
Please note, you need at least some part of the screen to be working, specifically, some part of the screen where the pattern lock is.
You only need two pieces of software. The Android SDK and the Nexus 4 Toolkit http://forum.xda-developers.com/showthread.php?t=1995688
If you are running 4.2.2 you will need to update the toolkit. I also had the standard issues of installing the USB drivers for the N4. You need to get to a point where is shows up as an ADB device in Windows Device Manager.
As I didn't have USB debuggin enabled I couldn't connect tothe phone via ADB, but if you put it into recovery mode you can use Fastboot. Hold down the power key to turn the device off and turn it on while holding down Vol Down to load up recovery mode.
If you then start the N4 Toolkit, you should see the device listed as a fast boot device.
From within the toolkit unlock your bootloader.
Flash a temporary bootlader, (option 10) as the touchscreeen was broken it has to be CWM.
Once in CWM you can start to use ADB. Open up a DOS command prompt in Windows, go to your SDK/platform tools folder/ to access ADB.exe and you can use the pull command to copy folders to your PC. At this point, instead you can use applications like ADBexplorer or DroidExplorer to do the same thing through a nicer GUI.
If you'd like to still be able to use your phone, although without the touchscreen, you can load an unstable image to get into android and then use ADB to start changing system settings.
Firstly, before exiting CWM, clear the cache. Without doing this the phone jsut hung on the Nexus symbol while loading the image.
in the toolkit go to root/unroot options and select load unstable image(option 4 and then 6). This will fire you up into Android and it should be set up as you left it.
I wanted to enable bluetooth so to use a keyboard (I didn't have a mouse but this is a better option) from the DOS window type the following command
am start -a android.bluetooth.adapter.action.REQUEST_ENABLE
You should eventually get a pop-up on your screen saying that a request has been made to enable bluetooth. Hopefully your screen is working enough to select enable.
Then I use the workaround to disable the sceenlock, found here -> (http://www.addictivetips.com/androi...e-pattern-unlock-on-android-via-adb-commands/) I found method 2 worked for me. I imagine this will be stopped in a future update.
Method 1
adb shell
cd /data/data/com.android.providers.settings/databases
sqlite3 settings.db
update system set value=0 where name='lock_pattern_autolock';
update system set value=0 where name='lockscreen.lockedoutpermanently';
.quit
Method 2
adb shell rm /data/system/gesture.key
If either of these methods are successful you will be able to unlock the phone with an pattern, hence why you need to be able to touch some part of it.
From then, my bluetooth keyboard was already mated to my phone to I was able the navigate the menus to turn on USB Debugging, turn-off the screen lock and a few other bits and pieces I needed to do.
I then restarted (I was still working within the unstable image) and on reboot, all my changes had al been applied. No screen lock, bluetooth enabled and USB Debugging enabled.
Hopefully this will be of help to those in a similar position. Thanks has to go to the toolkit though which provides all the necessary access to carry this out.
I should probably add, you can use the toolkit to relock the bootlader if you're concerned about that and if you can't click the screen to enable bluetooth or mate a keyboard or mouse, once you have USB Debugging enabled you can use software like Screencast to control you phone's screen from a PC.
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.key11. 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
Does unlocking bootloader via toolkit not wipe everything? How are you unlocking bootloader and still able to pull data off?
EDIT: it appears fastboot oem unlock on the Nexus 4 *does not* wipe data!

Please HELP, i can get to step 5...but then, when I try to use ADB via cmd (ie. adb shell), it says "error: device offline". what can it be? I don't know if this is a driver related issue (i've tried the toolkit drivers and the SDK drivers)...i'm desperated, I can't access the phone!!
Thanks in advance
not working for me
i'm in same boat with cracked screen. i can get CWM installed but i cant enabled usb debugging without touching the screen so i cant get adb working. how did you turn on usb debugging without the screen
Thanks for the guide.
Im curious on why youd want to boot an unstable(temporary) image after pulling the files using ADB in CWM recovery. Why not just wipe cache and reboot normally into Android ?

Can someone please walk me through how to do this? My screen is completely broken, but I can still turn on/off, I have reason to believe debugging is off because when I connect the phone (a Samsung galaxy sII skyrocket) to my Toshiba laptop via a micro USB, it makes a sound to signal that it's connected. Drives E and F then open up (but are empty) and then disappear. I have no idea what's going on but I absolutely cannot lose all of the data on this phone. Pictures and videos from my old blackberry Torch are on here too, making up about 4 years of my daughter's life that I would lose if I cannot retrieve. Also, I am not super -tech savvy, so if someone could help me I would be forever grateful.
Please!!

My screen became unresponsive a while back. I ended up getting and OTG cable and plugging in a mouse. This allowed me to do everything as if the touchscreen was working. There's also an app called MyMobiler that let me plug in my device over USB and control my screen from my PC. Those two helped me enable USB Debugging, flash a custom ROM, root the phone, backup everything I needed, then restore the phone to stock. I hope this helps.
*Sorry for bumping such an old post*
Thanks for the really useful guide!
Could you or someone just confirm to me that unlocking the bootloader does not factory reset? The reason I'm doing this process is to access my personal data so it's important that I can keep it all.
I ask because at the unlock bootloader stage it implicitly warns me that there'll be a factory reset.
Thanks again!

In that case, I am confused as to how OP managed to unlock his bootloader. He actually states that the purpose of this was to retrieve data, like me.
Also, in a previous comment in this thread by jw95275, they claim that "it appears fastboot oem unlock on the Nexus 4 *does not* wipe data".
I am concerned about the conflicting answers so far, so will hold off for an explanation before I do anything. Thanks for the response!

This did not work for me. I have a Nexus 4 with a broken digitizer, locked bootloader, and usb debugging disabled. I need to grab some data off.
I've tried `fastboot flash recovery {{recovery .img}}` and `fastboot boot {{recovery .img}}` without unlocking the bootloader first, and via both methods, I get back "FAILED (remote: not supported in locked device)"
So I'm not sure how people are able to get into custom recovery without first unlocking BL/losing all their data. Can someone explain?

On some (few) Motorola devices (not nexus 4), you can fastboot boot without unlocking the BL.
I just got my Nexus 4 and installed SDK and drivers on PC. OK, so now I boots my phone into fastboot mode, I connected it to my PC, entered"fastboot devices" in command line, no problem, I can see the device with the ID.
But when I entered"fastboot oem unlock", the command line it says" FAILED <command write failed <Unknown error>>". And the phone stays in fastboot mode without any pop-up.
I use USB 2.0 ports on the backside of the computer. Also USB 2.0 on my laptop. None of them work.
I tried to factory set the phone, restart computer and phone, change to another computer, none of them worked. Maybe I should contact Google to ask for an exchange because mine can not be unlocked?
Any help is deeply appreciated.

Only applies to ADB, not fastboot

Hy There i finally got my nexus 4 two days ago, i tried to search Google about bootloader limitation if there is any? Im pretty freaked cause i previously used xperia S with bootloader impossible to unlock, due to a carrier lock.
So is there a metod to check if bootloader of my N4 is possible to unlock like in hidden menu *#*#4636#*#* wich i cheked but i dont know to what i should pay attention? or is there the other way to chek .
I know that unlocking and rooting should be possible in N4 but i hope u understand my concern cause i bought N4 trough carrier contract and a negative expirience with xperia s, thanx

No, a Nexus device will ALWAYS have an unlockable bootloader.
I don't know if anyone has said this yet, but are you sure you're in fastboot mode when you type: fastboot oem unlock?
that command only works from the bootloader, not from inside recovery or when your system is booted up.

I just rebooted into the bootloader mode, hooked it up to my computer. Typed
fastboot oem unlock
There was a warning just after, accepted it.
then I downloaded the latest TWRP (2.5.0.0) for mako (Nexus 4)
fastboot flash recovery name-of-recovery.img
booted into recovery, made a backup of my Stock rom, wiped /system /data /cache, used the following while in recovery
adb push name-of-my-rom.zip /sdcard
adb push name-of-google-apps.zip /sdcard
then installed both via recovery and rebooted into the fresh new custom rom.
If I had not installed a custom rom, and I were to leave TWRP into a non-rooted stock:
TWRP would instead warn me that it doesn't appear to be rooted, and if I would like it to place SuperSu on it, it would do so, and I would reboot into the stock system, launch SuperSu where it will ask me if I would like it to reboot into recovery and install the su binary. Which it does automatically, so stock-wise that was the cleanest way for me to get rooted on stock (with an unlocked bootloader)
---------- Post added at 09:03 PM ---------- Previous post was at 08:57 PM ----------
By the way just as a recap.
fastboot works in the bootloader mode.
adb works in recovery and in normal system (with usb debugging enabled).
i read that it can be fixed by unlocking and rooting. problem is it is a friends and he doesn't know what version of android is on it. also can't put it in usb debugging.
Install this using Fastboot which does not require USB debugging. Simply download the factory images package then extract into the ADB folder. Typing "flash-all.bat" will flash all stock images including the boot, recovery, system and data.
thank you that worked

Is there any way to enable USB debugging or ADB through the command line fastboot?

Is your bootloader unlocked? If not boot into fastboot mode and type the command fastboot OEM unlock follow the prompt on the tablet and it will reboot now try the flashall.bat again. There is no way to enable USB debugging without selecting it from the menu that's a question that has been asked many times before

No. Sorry I forgot to mention that. My bootloader is not unlocked. And when I tried to do the fastboot OEM unlock, that is the only time the screen changes and gives me the option to unlock. When I scroll to yes and push the power button, the terminal says erasing user data and then it just gets stuck there.
I suspect that there is some kind of reading or writing problem.

OK if the bootloader won't unlock that sounds like a corrupted nand partition which would mean the internal memory is unwritable. One more suggestion try downloading wugfresh NRT use the unroot back to stock option tick soft bricked and force write. I'm not sure it will work with a locked bootloader.

OK well it looks like you are at the new motherboard stage then. Fastboot OEM unlock failing is a pretty sure sign that the internal memory of your nexus has become corrupted and it is no longer possible to read from or write to the tablet. If you have warranty now would be a good time to use it. If not eBay is a relatively cheap place to get a replacement motherboard. Sorry I can't be of more help than that

I have the afore mentioned Nexus 7. Have all the toolkits and proficient in adb. Get to the unlock prompt for the bootloader and press power over the yes option. It comes back up in bootloader locked every time.
I am in an endless loop otherwise. I can load to safe mode also.
Have the 4.23 bootloader and was trying to take the ota to 4.4.3.
Used two different aio toolboxes both with no luck. Tried to force load a stock rom. No luck. It just keeps booting back to how the tablet was before the update then reboots before you can do anything.

If you are proficient in adb like you state,then drop the toolkits.
What commands are you using? Does adb recognize your device?
Toolkits or cmd prompt the result is the same. Bootloader acts like it is going to unlock but doesn't.

I too have this same issue.....
Once I get the unlock screen (using tool kit) and select yes.... it goes to reboot, but the tablet never comes back on...
Once I turn it back on, I never get passed the "Google" screen....
The tool kit ADB see's the tablet and runs through the "unlock" yet it never takes....
I assume that USB debugging is not turned on... but I can't get the tablet to start it up to turn it on...
Been trying SKIPSOFT ANDROID TOOLKIT.
Can anyone help?
Try the other toolkit.

Yes... I have attempted to unlock the device 3 times...
I have used 2 different tool kits and adb fast boot....
They attempt to unlock the device.... but as the unit goes to unlock, it goes to reboot and the unit doesn't come back on... If I manually turn it on, it still shows the unit as locked...
When using abd, the unit does try and unlock and then when it reboots it shows that it unlocked the device yet the device still shows locked..
I'm at a loss right now as to what I should do....
That's a problem. (Not being able to unlock with fastboot can be a sign of corrupted bootloader/partition/emmc)
Have you tried to factory reset your N7?

Yes... I tried a factory reset..... but, as of now, I can't get to that option... If I try to get into recovery, it just goes to an image of the android with a red "!".......
In that case, it's most likely a hardware failure.

That's normal
I got the Same thing when I try to boot to stock recovery
Long shot as this shouldn't be possible, but I figured I'd try asking here anyways. Is there any way to unlock a 6P that's pin-locked by Android's Device Manager?
The goal is to get the pictures off this phone. It was my brother's phone before he passed away and I've been holding on to it for the past few months - just haven't had the energy to try to deal with it...
-I have access to the gmail account.
-I tried changing the pin through Google's device manager, but since the phone was already locked, the new pin did not take. I get the message on the phone about the new pin, but it doesn't unlock it.
-Developer mode is not enabled (i.e. USB debugging).
-Not rooted or anything like that and most likely has the latest updates (t-mobile). As a matter of fact, the lock screen says that a new system update has been downloaded.
Thanks.
Try putting twrp in your adb folder, boot into fastboot and use "fastboot boot twrp.img"

The only way I can think of is by installing twrp on the phone. The only way it wouldn't work would be if he didn't have USB debugging enabled, which if he didn't then you might be out of luck... I'm so sorry.

Unfortunately, I am pretty sure USB debugging is not enabled...sorry that's what I meant when I wrote developer mode (I've tinkered with making apps, so I know what it is).
Thanks.
Same situation here and I try to figure a solution for many days.In my opinia the only way to bypass is a modified google account manager ! Could anybody help?
@clappe Just pretty sure? It wasn't mentioned in the OP, so I'll ask. Have you tried to install ADB on your PC and using ADB pull to grab the files from /storage/emulated/0/DCIM/Camera ? That's the directory to the location where the pictures are stored.
Also, to anyone mentioning TWRP. That's a flat out no-go. He stated bootloader was locked. You can't do that unless you unlock the bootloader.
Edit: He didn't say that, I assumed when he wrote not rooted or anything. Can you power cycle the device? Hold power until it shuts off then boot it up again. Do you see a padlock icon under the Google logo right when it starts up or no?
Edit2: Later today (after work, around 10 hours or so) I'll flash my 6P to stock factory images and relock my bootloader. I'll use device manager to pin lock it and pretend I don't know the password. I'll try a few things and see what I can do. Also, you have my condolences. Sorry for your loss.

Connecting the device to a Windows 10 PC, it will recognize the 6P, but using Windows Explorer will show no files.
Running 'adb devices' lists no devices.
When I power on the 6P, first I get the 'Google' text logo, then the colorful 'spinny' android logo, then the 'android' text logo. Then it goes to the usual lock screen (shows the time, background, etc). On this screen are the normal shortcut buttons on the bottom - microphone, padlock, camera. After a few seconds it shows the 'Locked by Android Device Manager' screen, this has a padlock symbol in the middle along with the pin code that I set online through Google's device manager.
Thanks.
Might be worth a shot to try to contact Google. You'll need proof of your identity, and the passing of your brother though. Best of luck. Sorry about your loss.
If you end up not being able to get a rep that can help via email or phone calls; you might have to do a hardmod.

Hardmod? I did a quick search and the only hardmod I found was to deal with temperature.
Thanks.
