Need help with old Nexus 4 - Nexus 4 Q&A, Help & Troubleshooting

So I basically went into my drawer today, and found my old Nexus 4 and might I add its looking far from okay
Anyway, the problem is, the display will light up when turned on and the phone will obviously function as normal, apart from one thing, the display won't actually show a picture, just what looks like the backlight, and the touchscreen therefore will not respond, I basically have no screen for the phone
I need to get rid of this phone but first I want all my files gone, or at least I want them all backed up on my PC, as we as this I need some sort of screen mirroring software I can setup on my PC to actually see my messages, so here's what I am asking for
1. Is there a way I can push every file from my phone to my PC?
2. Bearing in mind I have no display/touchscreen so I can't install apps, is there anyway I can mirror the screen to my laptop?
I will add that the phone does have root with a custom ROM (I think CM11) and I am not sure if ADB debugging is on, I haven't checked this phone for 7 months
Thanks!

Boot into recovery then adb pull /data/media/0 to your pc (c:\yourfolder)

[Q] Can't get Nexus 4 (broken digitizer) to control on my computer

Hello guys,
This is my first post in here although I come to the forum from time to time to stay updated about new stuff. I hate to post this but I'm quite desperate now.
I own a Nexus 4 which I rooted and unlocked with no problem at all, a few days ago it fell off of my pocket and the screen is smashed now. Although it's still working: I can see what's going on in it, the digitizer isn't working so I can't really do anything with the device.
I really need to control the Nexus 4 on my computer (through a VNC I guess) to do some last things with it, but I can't get it to work. I'm running TeamWin Recovery (touch version) and last stock ROM if I remember correctly.
So the thing is: all I can do is reboot in recovery (in where I can't do anything, since it's a touch version) or turn on the phone as usual. If I'm in recovery, I can connect with ADB and use Android Screen Monitor to connect and explore my files (but since the device is OFF, just in recovery, I can't see the screen or control it). If I turn the device on, I can't ADB anymore, I always get a device not found error.
I tried with several drivers and different VNCs with no luck at all. I managed to install some VNC-servers apps pushed to my Nexus 4 using Google Play on the computer, but I can't open them (obviously).
I don't care how to do it, I just need to see and control my Nexus 4 on the computer knowing that I can't use the screen on the phone at all.
I've read for hours and tested stuff for days, with no luck at all, I hope you can help me on this.
PS: The device is connected to my WiFi network and also by USB, but I can't open any of the vnc-server apps with the phone and can't get adb to work so I'm a bit clueless here. Probably there is a very easy way to do this and I'm just messing around.
Well, thanks in advance.
1. Since your phone is rooted, use the tool kit and make a full backup to your Computer.

[Q] Cracked Screen, backup/restore options..Pro's needed.

Hey guys,
I cracked my s5 screen and need to backup everything and restore it onto another s5.
Phone info: NO ROOT, Pattern-locked screen.
I tried a lot (I mean A LOT) of different methods, and if I would be able to successfully backup/restore with a few easy steps, I still would like to have the following questions/methods answered.
They are as follows:
1. USB debugging mode is enabled, so i can use adb commands, which I have already. I have done the pull /sdcard/ command. I was able to get pictures, videos, downloads, etc. But I dont think it backed up any apk's. Any idea as to which pull command can fully backup the phone including apps, and if possible also text messages??
2. I have purchased a usb OTG (On-the-go) which allows me to connect my mouse to my phone. I cannot see the screen so i tried to randomly swipe my lock pattern, but i wasn't able to. So, what I thought of was to connect my phone to my mac, and use android screencast (which shows my phones screen on my mac monitor) while also using my mouse to control my phone. However, the USB OTG only has 1 usb slot, so I can either connect my mouse, or take out the usb otg adapter and connect the micro usb directly to my phone that connects to my laptop.
So the question is. Can I connect two micro-usb's into my phone simultaneously? One would be the usb-otg adapter( to connect my mouse into) and the other would be the micro-usb that would connect to my mac(in order to see the screen.) This way I would be able to control my phone with a mouse, and see my screen on my laptop monitor. I use mac btw.
3. If I can't connect two micro-usb's into my s5, can I enable bluetooth to connect to a wireless mouse via abd commands or any other method?
3. Can I root my cracked-screen phone? And without losing any data?
4. Is there a way to disable the pattern-lock on my phone using adb commands? I have read solutions to this for older galaxy models, but they didn't work for my phone.
Yes, these are tough questions, and I hope some of you have the proper knowledge and patience to answer them.
Please be specific, and note the Question # you are providing an answer to.
Thanks

Your post doesn't quite make sense, which I think is because you're leaving something critical out or making an assumption that you aren't telling us about. e.g. you cracked your screen.. okay. I'm sure that is frustrating but how does it cause you any significant difficulty in using your phone?
There is something that you're not telling us. We can't see your phone or tell what you are thinking.. did you forget to mention that you broke your digitizer? Or perhaps broke the LCD, so that your screen doesn't power up? Or something else?
Tell us what the actual problem is, because a cracked screen per se would not impair normal phone use. If we don't know what is going on, it's hard to offer good advice on how to proceed.
If you do a search, you can find posts describing how to bypass a pattern lock if USB debugging is enabled. If you can't view your screen directly for some reason, there are various ways to root or even easier, assuming an unlocked bootloader, simply install a custom recovery.. which is only a few clicks. Then boot to recovery mode, allowing you to run a root ADB session and use the dd command to backup your partitions.

Yes, the digitizer is cracked as well, and my screen is black. That is the reason I am using Screencast to view my screen on my laptop monitor.

I am guessing you can see the screen on your PC. Well, you can open up Google Play on your PC browser, search for the app "Helium backup" and let it install on your phone. That app can backup all your app data and other stuff as well I think, but I know for sure that it can backup the app data, which I assume is what you desire. The data can even be backed up to a Cloud. From there it should be easy to restore on your new S5. Also, the messages etc. are backed up on your Samsung account, that shouldn't be a problem as well.

Backup w/ Broken Screen? (TWRP Installed)

Hey guys, I recently broke the LCD on my Note 3 running stock KitKat ( :crying: ) and realized I hadn't done a nandroid backup in quite some time...
I tried the obvious adb pull, but for some reason I couldn't even get into adb shell or see my device in the device list like I had previously.
I'm all out of ideas now...
Could somebody please throw some help my way?
Does your phone even boot up? Do you get sound, vibration, anything to indicate it's still working internally beside blank screen?
Are you going to try to fix it? buy new one? upgrade to Note 4? Me and my wife used to own GS3 and when she broke her screen, I swapped motherboard with mine to copy pictures mostly and some other stuff, but we werent going to fix it, since I decided to get her GS5.

I'm getting a replacement through the phone insurance. It does turn on and function perfectly normal, the screen just has a tiny, tiny fracture point with a crack spanning across the screen horizontally, rendering the bottom half unusable. The top half is functioning though.
I cannot unlock my phone or make a backup with the bottom half not working.
Try using a bluetooth mouse or wired mouse with otg cable

Could help, made for exactly your problem. If you manage to get it working download Nandroid Offline backup, which allows you to make a Nandroid backup from Android itself, rather than CWM/TWRP.
EDIT -- Just checked and it works an absolute treat. Providing you had USB Debugging enabled before your phone got broke, it should work fine. It even has the option to swipe to unlock or disable a pattern unlock if you had one enabled.

Thank you for the link - it looks like it would be a great solution, but unfortunately I cannot enable USB debugging with the code given :\. I may be out of luck
Well, if nothing else works and data on the phone is that important, then you need to convince the insurance company to send you new Note 3 first and swap the MB as I suggested to retrieve the data, then put everything back to original. I have not done this on Note 3, but GS3 was probably one of easier electronics repairs I've done, just follow one of many youtube videos, to make sure you don't break some wire, before disconnecting. Possibly a shop could do that for you.
Well, freakin sweet deal. After being on the phone with the insurance company and US Cellular for two and a half hours and having them tell me everybody was out of Note 3's and they would only give me $400 bucks for my old phone minus my $175 deductible, I received another call from management at the insurance company apologizing and letting me know that they'd offer me $725.
It just so happens the new Note 4 is $770, so thank the Lord I'm in a good spot!

possible to extract content from an S4 with a broken screen?

Broke the screen on my I337 *AGAIN*. It`s an easy enough task to replace it (done every galaxy I`ve ever owned, plus my LG G Pro. Yes, I`m rough on devices) but I`m not really feeling the $80 for a new screen and LCD for a second time, what with the thing being three generations old and all.
I`ve got some data store on it that I need, contacts and whatnot, and with the screen not responsive, I can`t get it to unlock, let alone into it to back anything up to the card. Is there a way to get into it with my laptop? I`ll put a screen on it if I absolutely must but I`d rather not.
If you have ever enabled USB Debugging in the Developer section of the phone you are very lucky as you can use ADB (DL) with the appropriate sgh-i337 driver for windows. Using this you can grab any file you want from your phone. Just check for a tutorial on how to do this. This will def work.
Otherwise check if Smart Switch would do the job. And I would recommend downloading the driver from the soulution i gave before then install Smart Switch - So it doesnt have to find the driver and all since its present (or maybe it wouldn't download at all). Second method, im not that 100% sure if it will succeed.
Thank you, that should help a lot. Debugging is generally activated the day I get a new phone because I just can`t seem to leave the ROM alone for long LOL.
Glad I could help you

Screen doesn't work anymore! Please Help!

Hello there,
today, it just happened out of the blue, my pretty new S7 does only show up a blank grass green screen now! It can be turned off and on, touch works. I just can't see anything at all anymore. I really need a way to mirror the screen to the PC or something... USB debugging is not active :crying:. There are some apps installed, I need to use because I have to create the backup files in them!
What would be the easiest way to get access to this?
The phone is connected to my WiF if that helps.
Thank you so much!
I need help really urgently. (
Put it in download mode and reflash in odin

If you can aquire a mhl cable for your s7 you will be able to output the video output of the s7/edge to a tv/display. Just search mhl cable for s7 edge on amazon or ebay and you should be good to go.
Edit: just read the s7 and the s7 edge don't support mhl so you might be out of luck.
@Rydah805 I want to backup my data .... and I don't think that would help at all. The screen is pretty much done.
@amar95353 I read online that there is no more MHL support on the S7 anymore.

Your SOL on data. You can try SmartSwitch on PC but even then you'll need to approve the backup via the phone.

Original answer deleted. I'm a complete idiot. I should have checked but believe I was given incorrect information from my sprint sales person on location of reset. Sorry.
I turned off the phone many times.
Phone works fine, just the screen doesn't. I found a lot of forum posts for this problem it seems common...
I didn't root this phone.
Now, I finally know what's the hole for LMAO! What does happen if I poke it? Update: Hey, that hole is not used for resetting the phone. It's for noise reduction.
I don't think this will help on a broken screen anyway.
slaldrich said:
i assume you turned your phone completely off and on again (not just the screen).
If you did that, did you try a reset? There is a little hole on the top of your phone and in your box, you received a little tool. Poke the hole and hold it in until something happens (a few secs). This sort of reset is like pulling the battery. You should not lose any data in doing this.
If you created this problem by trying to root your phone unsuccessfully... Then you will probably need to odin new stock software.

please dont put anything in that hole. This is not a reset button............... ITS A MICROPHONE and that tool its design to open the sim card bay.
Don't worry, I wont do that.
I'm so stuck here... and also I need to send this phone to T-Mobile! Right now I 'm using an iPad as a phone replacement. lol
Just wish I could save this data...
Is your screen experiencing this?
http://i.imgur.com/iOmtR2T.jpg
If so, it's a defective screen.
I got mine replaced already since it was under 30 days replacement guarantee. You can read more about it here: http://forum.xda-developers.com/showthread.php?t=3359221
But the bad news is you won't be able to backup anything. I had to sacrifice a lot of stuff as well.
This is exactly what my screen does look like! And I did not only had problems with the screen, I wasn't able to get my carrier's settings automatically, I have problems with the charging, it won't display my phone number in the settings and also sometimes the camera app freezes. I installed the updates which didn't change anything. This new smartphone which doesn't even has a tiny scratch, never fall down is totally wrecked. Really disappointed about this "top high end" phone. I don't trust, that it will work after they "repeard it". I have it since release.
It's like really a huge amount of data... Of one app it is everything from 2 years (7GB)! There is no possibility to create a backup, you can just send the data to a new phone via WiFi that's all. If your phone breaks everything is lost.
I realized many app developers don't take enoughh care of backup solutions.
Yesterday the screen got back to life but just for a short moment
So it seems like there is no way to get back this data...
Can I get back my WhatsApp backup at least? I was able to create a backup before the screen died. When I plug in the phone to PC I can see "Samsung Galaxy S7 Edge" in my explorer an that's about it. When I click on it there is no content to show.
I just got an idea how to enable the god damn USB debugging!
Can someone share here how to connect the device as a mass storage to PC (by screenshots please)!
I was just thinking, I can work my way to the Developer Options by taking screenshots but I need to access the media for this!
When I connect the device to PC and then click on Samsung Galaxy S7 Edge it's empty... There most be done something before.
Thanks!
You guys can call me a ****ing genius! I managed to install Teamviewer by taking screenshots and look at them on the PC (I set up the device as mass storage blindly) so I knew what to do next. It was still tricky but possible.
I'm recovering my data now.
Thanks to the Google voice app I was able to type in "Teamviewer"
Thank you anyway!

It wasn't really easy dude... The most difficult was to make this damn thing work as a mass storage device. So I could finally have access to the data on the Windows Explorer.... I was just touching on the screen like a maniac!
But this is a way to do it guys. If you own a Galaxy S7 Edge I recommend to activate USB debugging and install Teamviewer quick support (Samsung version, there are different editions) just in case the screen breaks. lol I install Teamviewer on all my devices now...
Hey! The same thing just happened to my phone an hour ago. Green grassy screen. It's terrible!
Ok, so what were the steps you took in order to get to where you can turn on USB debugging and backup your phone?
Well, what happens when you connect your phone to your Computer (USB)? If nothing, then you need to check connect the device as camera or mass storage, blindly! Which is kinda tricky... You need to pull down your notification bar and then select the USB options thing and in this menu which pops up you need to select camera or mass storage... But once you get that done, you're good to go! You will be able to take screenshots and view them on your computer instantly. You don't really need to care about USB debugging, you can just get Teamviewer Quick Support (for Samsung) that is really important, the normal version won't work!

Thanks for the reply. It actually looks like my issue was much worse. My phone degraded pretty quickly, since I wrote my post. It got to a point that while I could type on my lockscreen, it wouldn't go past and enter the OS. I didn't even have a green screen anymore, the screen turned to an off black. At that point, I gave up and sent it in for repairs. I think the motherboard got fried.
