Screen destroyed, phone turns on data recovery help needed - LG V20 Questions & Answers

My v20 screen is completely black on boot after a nasty fall. I cannot get into the phone via adb, vnc, etc.
I had the restart pin set and am completely lost on how to recover my data now. I read about the OTG hdmi, usb adapter but will that even work when I cannot see the screen?
Need help, thoughts, opinions, etc... :crying: :fingers-crossed:

I work at ubreakifix,we have a decent amount of stores in America check to see if ones in your area if there is one they should be able to(if they have the screen in stock) temporarily slap a screen on there and move your data over for 49.99

If the body is bent, will it work? I'd Just prefer getting the data off on my own( using the otg cable), since I have to pay a $200 deductible to get a replacement phone...

[Q] Tricky and sticky situation!

So I have an LG G2 on my hands, I've dropped it twice now and the second time the screen shattered. And now it won't register any touch at all. My dad is going to India soon and he's going to look for someone to fix it there (because its cheaper in India I think). But the problem is, I want to back up my data before he does it and I don't know how to any more. I've tried plugging it into the PC but it won't register the device any more, tried installing usb drivers via device manager but no luck. Can'd do anything on the phone either because no touch. I'd be happy to be able to do a remote wipe, don't even care about the data any more. Just don't want anyone else to have the data (no there're no nudes on it, but other sensitive / personal data).
Any suggestions?

The phone can still boot, right?? If you have one of them USB on the go cables/adapter, then you could just plug in a mouse to operate the phone
Oh god why didn't I think of that! Brilliant! You, sir, are amazing. Many thanks!

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!

Verizon S5 - ClockworkMod Recovery? (Broken screen, need to enable USB debugging)

A very good friend of mine (whom I would like to earn a box of brownie points with) cracked the LCD on her G900V. The phone still works, alerts go off when she gets Facebook messages, etc, so that is good.
Initially I was going to use the MHL cable in conjunction with a USB OTG cable to gain access to it so we can get her photos off of it, as well as backup her SMS's and other things she didn't have backed up (read: everything). Unfortunately, for whatever reason, her phone will not display with the Samsung MHL adapter. It works on my Note 3, S4 and a busted LCD S4, but not on her S5. I think something else may have happened that caused the LCD to not work. It has been cracked for a while, but usable. Then one afternoon it just went black.
What I need to do is get USB debugging enabled so I can use ADB or AndroidControl to get the data / pictures off. After reading and reading, I came across a thread where it says CWM has debugging enabled by default. GREAT! I'm able to get the phone into download mode (ODIN recognizes it), but I can't seem to find an appropriate recovery to load on it.
Any help?
I'm 99% certain unless it was a developer device it has a locked bootloader, so not possible, sorry man.

I had the same problem with my S4. The screen broke and I could not veto the HML cable to work. I used it before to watch movies with the S4 so it must have been something to do with the broken screen. I didn't want to sell or give away my phone (or turn it in for warranty) with all of my personal data on it. My final solution was to swap the motherboard to another S4 and recover my data. While I was at it I wiped all of my data and encrypted the phone so nothing could be recovered from it.

Another possible variation on this is if youre already taking it apart, maybe just take out the internal sd card, im not sure how it works on this phone but on my old windows phone you just undid some screws and moved some foil stuff and the sd slot with the card was there, just dont confuse this with the already exposed one.

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!

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.

SM-G900V - Broken screen. MHL/Mouse/Keyboard(?) possible all at once? [SOLVED]

Phone fell out of my pocket and got run over. Screen is completely black and the digitizer is done as well. If I connect it to my PC, it comes right up, but I have no way to enable USB file transfer mode so I can't "see" the SD card or internal memory. I tried to use [email protected] with Android Control, but it appears USB Debugging is turned off on the phone as ADB tells me the device is "unauthorized" and [email protected] gives me a "Rejected" status when it connects with the phone. (Yes, I did remove the ADB keys from my PC's ./user/.android folder and tried again)
Recovery is stock so no ADB access to open a shell and tweak anything. I haven't run across an ADB enabled recovery that I can install on this unlocked bootloader. (I can get into download mode and Odin recognizes the phone.) so I thought I'd try the "simple" route.
I bought an MHL adapter and an OTG cable thinking I could use a spare monitor and a mouse to turn on USB debugging or, at a minimum, turn on USB file transfer so I can get my data off the phone. I connected everything up and I can see the display, but mouse movement isn't being passed through the MHL cable assembly. If I plug the OTG cable directly into the phone, the phone does react to mouse movement and clicks and I can get lucky and launch apps, but I can't see WTH I'm doing. The odds of me turning on USB debugging like this are slim.
Anyone know of an MHL adapter that will allow "piggybacking" a USB mouse or an ADB enabled recovery I can flash to the phone? Maybe some uber-secret method to turn on USB debugging without access via ADB?

Yep, have all this working. Replacement phone works so my config is correct. The issue is USB debugging got turned off somehow. If I can get in via ADB, I can tweak the files I need to turn it back on. Or, I can find a MHL/OTG combo that works and just turn it on via the screen. Hell, if I could view the ADB key on the phone, I'd modify that file on my PC and it'd probably work.

Read this one as well. I'm not sure what all gets nuked in the process nor have I researched ADB enabled ROMs. I have 2 files I *need* to get off the phone before I send it back. If I had local copies, I wouldn't sweat it and I'd boot into recovery and since I'm familiar with the order of the menus in there, I can probably do a factory restore. Unfortunately, the 2 files I need were updated/created while I was doing the errands that resulted in the broken screen.

Yeah, I've seen a bunch of those, but have read several reviews that state it does not work with the S5. I wish I could find one locally just to try it out and if it doesn't work, I can return it without too much hassle.
Just spent almost an hour on the phone with Verizon and Samsung. The 2nd tier person at Verizon said that if the phone was still activated, they *might* be able to get in remotely and tweak the USB Debugging setting for me. I would have to acknowledge the request on the screen, but that may have been doable via blind mouse clicks after seeing where the dialogue was located on the display. Unfortunately, the phone was already deactivated and without a working digitizer, I would not have been able to temporarily reactivate it.
Samsung was slightly better than useless. I had to explain several times, to two different people, the specifics of my situation and they couldn't seem to grasp the idea that both the display and the digitizer were dead and all I was looking for was a way to get MHL and OTG working at the same time. That concept seemed completely foreign to them and they couldn't tell me if the dock they manufactured for the S5 would do what I wanted. The capper was the last person I spoke to all of a sudden said, "Thank you. Have a nice day." and hung up while I was asking a question.
I called Asurion again to see if I could send the replacement phone back (Because the sound quality is so bad it's almost useless. Even the Samsung Advanced Support guy said the quality on his end was crappy.) and just get this screen replaced. They told me "That service is not available in your area (I'm in a city of approximately 1.3 million - surely they'd have a vendor here?) and "we don't replace the digitizer, only the glass." When I asked, "How is that possible when the glass, the LCD and the digitizer are all one unit (At least I've not seen the separate components in my searches) that you can replace the glass?" The response was a seemingly scripted, "We don't replace the digitizer." When I asked if I could just send this replacement back and replace the screen myself, they said the phone would no longer be insured. Same as if I had a "professional" swap it out.
At this point, it appears I'm dead in the water. I'm still going to research the feasibility of cobbling my own cable(s) together before I have to return this phone. This seems so simple to solve, but it's proving to be an exercise in frustration.
Having a little success in "driving" the phone now with the use of an MHL adapter and some swapping of MHL and OTG cables and a keyboard. I've verified USB debugging *IS* enabled, turned it off, revoked previous privs, turned developer options off, rebooted the phone, turned developer options and USB debugging back on.
I installed the Samsung USB drivers on my notebook and installed Android Control and [email protected] and tried again. Still getting an unauthorized response from ADB with a request to check the screen for messages. Unfortunately, as soon as I unplug the USB cable from the phone to plug in the MHL adapter, any message that may have been there disappears. I did this same thing on my replacement phone and after a couple tries, I got the Authorization message and was able to get that one "talking" again.
At some point I had installed a screen mirroring app on the old phone and managed to get WiFi working with some blind mouse clicks and got the mirroring working with a keyboard plugged in. It's VERY slow, but I was able to turn on BlueTooth as well. I ran out of time for the trial version of the mirroring app and can't seem to make it work again so....
I'm off to buy a BT keyboard and mouse. The plan is to try and sideload Samsung Smart Switch, use the BT KB/Mouse to "drive" and the MHL adapter to "see" and transfer data that way. Alternately, if I can get the screen mirroring working with BT KB for control, I could, in theory, reauthorize the USB stuff.
Alternately, what's the trick to making ADB work via TCPIP? I've been reading a few threads about it and actually got a brief response (Still unauthorized) early this morning (0230-ish) but have been unable to repeat that. Trying with my new phone ADB tells me it can't "see" any devices and "unable to connect to :5555"
Found a thread on Stack Overflow that mentions adbd insecure needing to be disabled, but I have no idea where that might be done.

And here is a chicken and egg. For you need USB debugging activated in order to provide you with an ADB shell. At least as I understand it.
Smart Switch is already installed, but I can't access the confirmation dialogue(s). If I can get the thing talking to the PC, I'm golden. I can pull my data and then do a factory reset.

That's strange. I managed to get it working on my Core Prime with a dead screen. Well broken enough. With no OTG support. And I wasn't aware of any dialogue on screen. I loaded up Switch in Windows and it communicated with Switch on the mobile fine AFAICT.
I can the phone recognized by ODIN and wouldn't mind attempting to flash something if it'll help. At this point, I'm considering this pretty much a lost cause so if something gets jacked, I don't care.

If your phone has a supported custom recovery then you have a chance.
Was able to recover an ADB key file pair from Saturday afternoon's initial attempt to get in to the phone. Still no joy. However! I *was* able to drive through the settings menus with a keyboard. USB debugging IS on and I was able to revoke USB debugging Authorizations
Click to expand...
Click to collapse
This started off well but if your phone had a list of keys already, even if you didn't know it is, then revoking the keys pulls rug from under your feet. So to speak. However, if you can satisfy the dialogue to authorise a new computer, then that's no problem and your in!
Am I on the right track with revoking authorizations? Any way to make the phone think I've never "touched" it with ADB? Again, the new phone connected right up with no input required from me.

I wouldn't have done that given it freshens the slate. But if you wanted to clear it to a near untouched state that is the way to do it. Strange the new phone was easy that way. In that case it would be a good idea to clear it if the old one acts the same.
Here is my story about trying to get USB debugging working:
https://forum.xda-developers.com/ga...how-recover-data-core-prime-sm-g360g-t3681433
Here is a guide I wrote from my story detailing how I hacked my adb key in to authorise my computer for USB debugging:
https://forum.xda-developers.com/android/help/guide-modfying-cf-autoroot-kit-to-t3725596
Now this details what's involved but my phone was fully unsupported by everything but the CFAR kit. Which I needed to hack. You shouldn't need to go to such measures. Just need a recovery with ADB enabled.

This started off well but if your phone had a list of keys already, even if you didn't know it is, then revoking the keys pulls rug from under your feet. So to speak. However, if you can satisfy the dialogue to authorise a new computer, then that's no problem and your in!

I was getting the "unauthorized" status of the device via ADB and had no way to compare keys. I revoked keys so I had a known starting point. Yes, if I can get to the dialogue to confirm the access, I'm golden. Going to try the BT keyboard/Mouse and screen mirroring this evening when I'm done for the day. Even if I get Switch to start talking and get my data moved over, I'm going to figure out the ADB thing - it's become personal.

USB debugging *is* on. I was able to verify that once I figured out how to drive "blind" with a keyboard. I was able to turn it off, turn off debugging options, reboot, turn debugging options back on, then turn on USB debugging.

Then you're half way there. Almost living on a prayer. And if you can do the above it should be a cinch to get over the line and get that computer authorised.
I'll have to try again but when I used Switch to move my wife's data from her Droid Mini to an S5, there was a confirmation dialogue on the Mini.

It may work different from a non-Samsung phone. I used Switch on Windows to back up data from my Samsung phone. It was able to do so without intervention on the phone. Well I didn't see any prompt on the phone. Since my screen was blank.

Aha. Well hopefully you can get it going without need of that. In my case my under supported phone wasn't locked.

Haha. Yes I know what you mean. You can see by the links I posted how personal I got.
I managed to CF-AutoRoot my phone before I got USB debugging even close to on. Of course I still couldn't do much with a broken rooted phone since all actions needed acknowledgement on screen. Later when I finally broke in and got the authorisation I still didn't have root access from an adb shell since that needed the screen working.
I had AirDroid installed. So once USB debugging was working I could do screen mirroring right away. That was a reward in itself. But it was the darnedest thing. The time I got it up and working suddenly the screen started responding to touch which didn't work before. I could brush my finger across the screen and hear the waters. So I quickly backed up my data. The next day, the screen stopped detecting my touch again. As well as AirDroid being unable control input. It's stuck in the corner and I can't use the mirroring to echo any touch to the phone. Most bizarre! I backuped my data just in time.
I used Helium to do a non root backup even though it was rooted. Worked well. Needed the mirror to see on screen.
I'm in! I was able to use my MHL adapter and a mouse via OTG to get the trial version of Stream Screen Mirror going. Once I got that going, I was able to pair a BT mouse/keyboard and use an MHL adapter to "see". Out of "spite", I fired up Android Control and authorized ADB access and voila! Remote screen and control. Pretty slow, but it works.
Sideloaded Switch via SMB and got it transferring data. It's grinding along now but will likely be another hour or so.
Thanks to everyone for the help.
That's good you got it going. Well done, I knew you would get there. Now if only there was a better solution than all this fiddling around.

No kidding... I can't imagine someone without any technical knowledge being able to move their data over in this type of situation. Oh well, it was a nice learning experience. I got a BT keyboard and Mouse for use with my Rapsberry Pi and now have a solution for the next time.
Actually, I think I'm going to root this thing and avoid all the hassle in case this happens again.
I agree with you there!
