Any way to unlock a V20 with a broken screen with pin required on restart? - LG V20 Questions & Answers

I JUST got a replacement v20 (like literally sent back my first V20 on thursday) for a v20 that wasn't quick charging. And I left it on top of a car when pulling out of a gas station and it fell off and promptly got run over. First cellphone I've ever actually broken or even cracked a screen on. So annoying.
Anyway, the phone was still working using my bluetooth headset but I didn't realize and the battery died shortly after. I'd like to try and backup a few things on the phone before switching over to my insurance replacement (specifically let Whatsapp backup automatically run at 3am and backup SMS messages) but I have the PIN required on restart option set. Everything I find online about getting an android phone unlocked with a broken screen seems to be talking about the screenlock and not the PIN on restart feature. Before I go buy an OTG breakout cable to use a mouse and HDMI monitor will that even work with PIN on restart? Can I connect to the phone with ADB before it actually boots into android (and set the USB connection as something other than only charge; not even sure I've set USB debugging yet since the phone is so new for me)?
It won't be the end of the world if I can't get into the broken phone, my photos are automatically backed up to Google drive, all my contacts, emails, tasks, calendar etc are cloud based (exchange server or gmail). Really the only thing I'd lose would be SMS's since last week, whatsapp since last backup, and my call log. But that would be really annoying to my pseudo OCD; I have an uninterrupted record of every text message I've ever gotten since treo in 2004.
Any help much appreciated.

I can't say for sure if it'll work or not but if it were mine the first thing I'd personally try would be (which you mentioned) an OTG with a USB keyboard or mouse. I'm crazy OCD myself so I know exactly what you mean about your unbroken backup of messages, I've basically done the same thing and like you said it wouldn't be the end of the world if I had to miss some.. but it would still suck nonetheless! Anyway hope it works out with ya.

Thanks. yeah I ordered an OTG adapter for HDMI and USB off amazon. Figure if it doesn't work for this, at least it's a good thing to have. And if it doesn't work at all for the V20 amazon'll take it back.

I'm pretty positive that the OTG adapter will at least work in general (not sure if it'll work for your situation but hopefully it does) because I basically made my own OTG adapter and it works just fine with mine. I made the adapter years ago by cutting off the female end of an old usb extension cable I had and splicing it together with the male end of an old micro usb cable, and then to use it with this phone all I had to do was plug the micro usb end into a usb c adapter and it still works just like it should. So I'd say if my Frankenstein setup still works then you shouldn't have a problem with yours at all lol.

Did it work?
So I have to know... did it work? I have the identical issue. Dog ate my phone, I have a PIN unlock on reboot, no display. I really want to make a backup of my settings before I wipe because I've finally got the phone the way I want it.

Hey man, sorry for the late reply. It did not.

Weird USB issue

I've been tethering my phone with PDAnet and just recently it has started to act up. The only way my computer will recognize and sync with my phone is if I put a little downward pressure on the usb cable (phone side). Then, if it gets jostled to much it'll disconnect and say "USB device not recognized" when I try to plug it in again. It will start working if I put my computer into stand-by or shutdown. But only once. What is going on?

Your USB port is flaking out. I have had it happen to 2 titans. They start as you describe and then get worse and worse until the port stops working completely. Then you take it back and get the insurance replacement (hint hint...if you do not have insurance on your handset this would be a good time to get it). When I complained to the guy at the alltel store the second time he said that it was common enough that he might even say inevitable.
Personally I think it is a poor design because the mini usb port on the titan (and the apache) are not really supported very well by the plastic housing. They fixed this with the touch pro (have not seen a diamond yet) so I am guessing it was a pretty widespread problem.
Not the answer you want I am sure, but the above has been my experience. If you need to drag it out (i.e make it last a little longer so the insurance you just added is not immediately and suspiciously followed by a new claim) you can always sync/tether using bluetooth instead. It is a little slower (1 mb) but not too terrible.
Why are you using PDA.net? Windows internet sharing works very well and is built in (free).
I use PDAnet because my provider would frown upon traditional method of Internet Connection Sharing. However, I appreciate you sharing your experience about the Titan with me. I love the phone, but maybe it is time to put her out to pasture.

Possible Solution To "Vibrant Won't Mount"

I don't know if this has been brought up before (search didn't find anything), so I thought I'd share. Both my son and I have a Vibrant. I have flashed just about everything out there (can't help myself ), but he has yet to take the plunge. Anyway, I wanted to pull some video he had shot during the New Year's Celebration, and couldn't get his Vibrant to mount. It would do the usual business about asking to mount and all that, but my laptop wouldn't recognize it. It would recognize mine just fine. I asked if he had ever hooked his phone up to his PC, and he said that he had, but hadn't had any luck connecting lately. He also mentioned that he had recently bought a new charger for it. On a hunch, I looked at his charging port, and yep, you guessed it, one of the usb tabs on the phone was all jacked up. (it was pushed all the way to the back of the slot, like there was a bad fit on the new charger??) Anyway, with a little coersion, I put the tab where it was supposed to go, and VOILA!! Connection problem gone! I realize that this will probably only help a few folks, but I figured it can't hurt...And no, I didn't think about getting a pic of it prior to the repair, sorry....Oh and sorry for the long post
Cheers!
Good observation I had the same thing happen on the other side My laptop's internal usb connection had a piece break off, and it took of investigating to figure out what actually happened

No charge, no sync - loose MHL cable port.

Only had mine 3 weeks and its broken already. I have been using a desktop charger and have not been forcing it in at all, not once, I have always been very gentle inserting it it, anyway it no longer charges, it looks like the connectors have pushed themselves back so they are not flush anymore and thus no longer connecting to charge or sync.
Not happy about this at all, I had my desktop charger for my HD2 for 18 months with no problems at all, this suggest a very weak connector.
!!! BE CAREFUL !!!
Going to call in at Phones4you and see if they will swap it, I don't hold out much hope though.
Wow bad luck man, but really you don't need the F word to express your frustration.

was it an official desktop charger or 3rd party?
DO a factory reset using code *2767*3855#
(please not this will wipe everything including built in memory, so do backup before you proceed. Backup possible by moving content of internal memory to SD card by copy paste in file manager)
I had a problem when my phone stopped charging after I upgraded firmware, It would also launch Connected to computer screen when it wasnt . Thought its dead.
Did factory reset using this code and its working flawlessly ever since. Seems to be some kind of bug which happens out of nowhere as 2 people I know have experienced this after upgrading to KE2.

I was going to ask exactly the same thing...
I think the OP means that the micro usb receptacle has come away from the board and has been pushed back into the body of the phone. I hope this is not going to turn out to be a common problem as it's something that seemed plague to the Nokia N900 and it took ages for Nokia to acknowledge a design/production fault.
great advice, now it wont boot at all, just goes round in circles....
F**cked.....
anyone got any ideas?
Hi, the charger isnt really the issue, i haven't had any problems inserting the phone into the charger, ie no resistance which suggests to me it was week or loose and has gradually pushed it self back over the last 2 weeks since I have had the charger. If thats the case it would have done this with any charger or cable.
Just spoke to phones4you, they are going to exchange it for me, they didnt even grumble after I told them what happened which I thought was odd, heading off now to pick it up.
Will be interesting to see if your wifi is any better on the new phone stoolzo. Maybe you could let us know. Thanks.
good old phones4you
got it already, yes I really have. Phones4you are just round the corner in PC world. Will check my wifi tonight and report back on the other thread.
Please change the thread title. All type of people view xda.

remove and reinsert battery
i had this issue when running custom kernels. somehow doesnt happen with stock.
issue happens like this:
u go to bed while charging
u wake up and the phoneis off or very hot with battery and temperature warning
u reboot and it doesnt reboot, doesn't boot, just goes in circle battery display/reboot cause it doesnt seem to charge neither have enough power to boot.
removing battery + cable then putting both back = it boots again and charge normally

************************************************************
Yeah, did all the usual things, I have bricked phones before and always managed to turn them around but we have no CMR to flash anything from ROOT/SD so when it wouldn't boot after a factory reset I knew I was in trouble
The MHL port being loose was the tell tale sign of a fault as I hadn't misused it at all. When I compared it to my new phone I got today it was defo a little further back, just enough to prevent it connecting.
Good old phones4you, fault report to phone exchange in under an hour, impressive.
Just in case the charger had anything to do with this I am going to get rid, dont think it did but I don't want to risk it.

Big voice talk problem and car mode notification

Ok so maybe I spoke too soon. Yesterday I was telling my brother that the Note is the most reliable phone I've ever owned.....then....
I started having issues with charging. My Note would not charge, then it would change after several resets. It would charge, then stop, then start again etc etc....making a lot of beeping noises.
Now, it seems to be charging, but Voice talk keeps loading, and I've turned off the home key activation option. I also get the notification icon saying to disable car mode.
I really hope someone can help, thanks in advance.
kris
Great, now it's not charging, again!
Actually when I get the notification issue from Voice talk, the battery starts charging for a second until the notification disappears and stops charging....
Now factory reset my phone again and charging worked while restarting and restoring but when loaded the voice talk app keeps coming up and going off, so I have a black flashing screen constantly....gonna try restarting/reset without restoring...
Hi leicashot, this shouldn't happen. Which firmware version are you currently running? I recommend installing the latest LB1 stock, unless you have AT&T Note.
Some users have reported similar symptoms when there was dust in the mini usb port. Try cleaning the device, and if all else fails, you should send it back to Samsung for repair.

I'm using the latest 2.6.35.7. Any idea how to try clean the port? Definitely seems like something is wrong with the port....
No charging issues for me but my Note started doing the driving mode thing at about 3am today and has been doing it on and off all day!
Exceedingly annoying!
are you trying to charge from a PC or a wall outlet?
I usually charge via mains but it wasn't charging or even plugged in at the time this started happening. It was just sitting on the table by my bed. I even powered it off but it switched itself back on!
Here is how to fix it.
Take out the battery and take a plastic edge like credit card or even a regular tiny small screwdriver and push the pins (strip) inside the phone. I mean, to take the screw driver and push in the pins back inside the phone, in inside the usb charging port. your problem will disappear. make sure your plastic flexible after-market phone cover has a big enough hole at the bottom to allow you to connect a usb cable easily to the phone, or else, cut open a bigger hole on the cover.
Good luck
so here it is again: you have to push in the usb port pins back inside the phone, straight in without bending them. you can also buy a usb charging port from ebay for 22 bucks and change it yourself in 10 minutes. its a hardware problem so stop resetting your phone.
Nop bro i dont think so, cuz it happened same with me sometime after i bought galaxy note same thing happened with me too. I mean exactly same. So before i didnt knew rooting and flashin roms and all so i gave to service centre and they put newer version of ron in it and my problem was fixed after that.

Indeed. I remain convinced this is not hardware and is software related. The main reason for my thoughts there are that as well as the driving mode thing it seems that some piece of software is trying to load up as it asks me if I want to run whatever it is in either Clock or TuneIn Radio. Bizarre. Also, the first time it happened it was bang on 3am. Everytime I turned the phone off it would come back on exactly two minutes later.
The second night it started doing it bang on 1am.
I'm waiting to see what time it starts tonight.
It doesn't (so far) do it at all during the day.
Going to give it a couple of days to see what happens then go figure out how to go back to a factory ROM rather than the the Rocket 22 I have on here now.

Same thing is happening to me. I tried pushing the USB pins in slightly. I'll let you guys know if it helped or not.

I've been having the same problem for a few days now.
I've just pushed the pins in with the corner of my charging cables connector and the problem stopped.
There was also a notification that flashed up saying something like: USB connector or device removed.
Voice talk is still managing to launch itself, even after pushing the pins in. I'm on stock LB2 so maybe I've finally found a reason to flash a GB rom?
Happened to me yesterday. Got a toothbrush and cleaned usb port on phone. Now seems ok

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!
