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.

Help with backing up N4 with cracked screen

My Nexus 4 LCD cracked upon impact today and the digitizer is damaged. I want to backup my phone before I repair the LCD, currently it is:
- Rooted
- USB Debugging is enabled from settings
- Device is set as "Camera" and not "MTP"
I want to use the tool http://forum.xda-developers.com/showthread.php?t=2786395
But I cannot tick the box for USB Debugging when using the tool, so I used the following in ADB in Recovery (TWRP)
Adb shell
echo "persist.service.adb.enable=1" >>/system/build.prop
echo "persist.service.debuggable=1" >>/system/build.prop
echo "persist.sys.usb.config=mass_storage,adb" >>/system/build.prop"
reboot

However, the device doesn't show up. In device Manager (Control Panel) and while I'm in recovery I get "mako" with a yellow triangle
for which I cannot install any driver (I downloaded them through SDK).
I think it's a driver issue and I want to get sorted to have access to my phone, any ideas or experiences would be welcome!!
Thanks!

It's probably not showing up because camera is selected instead of MTP, but my question is why do you want to back it up.... just Repair Lcd and it should be just like it was before lcd broke....

Good question, I suppose I worry that something might go wrong while disconnecting/reconnecting the mobo.

I have a business repairing phones.. nothing is going to happen when you disconnect the lcd and reconnect the new lcd... But if your phone has a frame I would Repair the whole frame and lcd together... Its much easier then just repairing the lcd alone

Well that's comforting, thank you! I'm trying to get the OEM part from LG, I found it in the market here in Saudi but it's not original, just a grade A quality LCD + frame.

I use either Amazon or ebay mostly Amazon because they have prime which means you get shipping free and some items you get in 2 days so if you order it on a Friday it comes on Sunday... Its free for a month and then $99 after that or you can keep making a new email every month to beat the system

Is there any other way to get to my files on the N4? or at least control the device with the cracked LCD?

Is your bootloader unlocked? If so flash twrp using fastboot. Then boot into twrp and you'll be able to copy and paste files from your device to your pc. If you can't see anything on your screen it might be a little hit and miss but it should be possible.

Yup bootloader is unlocked, I have twrp already but how do I choose the options in twrp? The screen doesn't respond! Also how do I copy files using twrp?

You don't need to choose any options (assuming you have one of the newer versions). All you have to do is boot into it. Boot into the bootloader, hit vol down twice and then power. Let it boot and plug your device into your usb cable. The device should show up on your pc.

That's the problem though, I had set it on Camera instead of MTP, so now I only get access to files like DCIM and NOT the rest of the files. Is there any way to circumvent this and have access to all the folders?

Have you tried booting into twrp? Twrp defaults to mtp mode so I don't think it matters what you set the device to.

I got into twrp, but again i had "mako" in the control panel device manager, so neither Camera nor MTP worked BUT then:
- I installed some drivers from the N4 Toolkit, namely the samsung drivers, and they worked. NOT MTP though, I am able to get into recovery and use ADB Pull commands but again for some files transfer is interrupted by "No such file or directory" that cancels the operation - so I need to somehow transfer directories/subdirectories individually..anyone can help out here?
- Other thing, though drivers are now installed correctly now, I still can't get to MTP and I think that might due to the fact that ive enabled USB Debugging. From my experience on N4 and N6 if I disable USB debugging I can use the device as MTP, if I enable it I cannot, I can only use Camera if it is enabled - so second question: can I disable USB Debugging through ADB somehow?
Thank u all!

Ok, I don't know the status of your device. I know with the latest twrp you can boot into it and access your device through mtp. Adb pull is a pita if you don't know the specific location and name of files. Here's what I'd do:
1. Google 15 second adb install xda. That'll install the usb drivers and fastboot with system variables set so you don't need to worry about the path to fastboot.exe.
2. Download the latest twrp image from here http://techerrata.com/browse/twrp2/mako. Rename it twrp for simplicity.
3. Boot into your bootloader and open a command window in the same folder as twrp.img is in.
4. Run the command
fastboot boot twrp.img
5. You'll be booted into twrp and with your device connected to your pc you should see nexus4. From there it is as easy as copying and pasting files from your device to your pc.
When booted into recovery it makes no difference if you have usb debugging checked you not

DUDE THIS WORKED!
One thing. The screen goes black, doesn't go to twrp but Nexus 4 shows up on my PC as MTP. Files are accessible. When I restart the device, TWRP is back to the old version I had.
Not important. Thanks a million buddy. God Speed!

Glad you got it working. Twrp is your old twrp because I just had you boot into it. Not flash it. If you want to flash it, fastboot flash recovery twrp.img

Broken digitizer Nexus 4, trying to control phone from PC

Hi there, the title explains most of it, I'm trying to control the phone with k.janku1's control tool, here : http://forum.xda-developers.com/showthread.php?t=2786395
The phone has USB debugging enabled, is in MTP mode and ADB will find the device fine when I'm in recovery but when I reboot the device ADB won't find the device when it's turned on. I don't know if I'm being stupid or not! I also have all the drivers installed etc

Never used that tool (I did not even heard of it before) but I do rely and suggested to all of my mates to test Chrome extension Vysor, so you could give it a try.

I can't get Vysor to detect the device, I have USB debudding enabled but I'm not able to use the device at all as the digitizer is broken

Ah, I've just read Vysor's troubleshooting guide, it says to be on PTP but I'm on MTP
Is there a known way to change to PTP from MTP with a broken digitizer? I can still see everything on the screen as it's just the digitizer thats broken so I can use recovery via using the volume buttons & power button

There is no problem with MTP, only changing the mode may help to detect some devices. If you are on Windows I strongly suggest you to download latest USB drivers. Eventually check your setup with another android phone.

Nexus 4 - Broken screen, no touch, need to unlock

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.

Activate USB Debugging

Hello Everyone!
Can somebody inform me on how to activate USB debugging when the screen is locked with a pin and the phone has stock software? Samsung phone with Nougat SW.

...
I have gotten this far with my windows 10 laptop which has adb tools installed:
Boot the phone the phone into Recovery Mode.
Select System Mount
Connect to PC and open CMD and change folder path where adb tools is located.
type adb devices in terminal
Now, the issue is that I see is a number followed by "unauthorized". I am trying to use commands such as adb shell, but seems like I am not allowed? I'm assuming it's because the phone is not USB Debug Enabled. I have a different phone which has USB Debug Enabled and adb shell commands are working perfectly. Any way to use shell commands or work arounds? Thanks in advance!

It is not possible to activate Debugging Mode with a locked screen. AFAIK it never was and it never will. And this is good as it is.
