Need help controlling phone with broken screen - Nexus 4 Q&A, Help & Troubleshooting

I know there are a lot of these threads but my intention is a bit different. This phone I gave to my daughter a few months ago and she cracked the entire screen (no touches register whatsoever). I want to take the phone and repurpose it to simply act as a webcam and point at my 3d printer. The phone is rooted and nothing on the phone needs to be saved. I bought an OTG cable without really reading into it enough to see the default one won't work.
So here's what I want to do. Somehow get some kind of vnc server/anything installed so that I can control it. The wifi currently connects so I'm good in that regards. The one damn hurdle that has stopped me is that the phone does not currently have debugging enabled so I cannot install apks over adb.
Any ideas would be greatly appreciated. The value of this phone is far outweighed by the price of a new screen so an actual repair is not in the cards.

LCD/screen cracked. Need help ASAP Please

Not sure how it happened as it was working fine but all the sudden my LCD/screen is malfunctioning. There's a big burn spot in the middle of it and I can't make out anything. The phone still works. I upgraded to the AT&T Tilt yesterday. Not sure if I'm going to keep it or not, as it takes a micro SD. Anyways - I had this program to backup my cemail and pim files when I had to have my 8125 replaced a few months ago. Well, now I need to be able to pull them off the phone or at least run the backup to get them to their current state only I can't see the screen enough to navigate around. I saw a program, pocket controller that will let me control the phone on my desktop but I need help installing it or a similar program. I can't see my screen at all so I'm doing it blindly here.
Is there anything I can do here? Should I keep the Tilt or Return it and send the 8125 in to get the screen replaced?
I was in the same situation. I bought a new LCD from Ebay for ~$60 and replaced it myself. I got one from the seller lcd4pda (item# 280163983616) and it came with the necessary tools to replace it. It was not very easy to replace the LCD and I broke several plastic hooks along the way while opening the phone, but in the end I have my phone working. Oh, I am not affiliated by the seller in anyway, I was just happy about my purchase and wanted to let you know about that.
I don't know about controlling your phone from your PC, but you can copy any file from your phone while your phone is connected to the computer. There should be a link to your phone in "My computer" while it is connected where you can access the files on your computer.

Help me get an antique xda going

Hello, I will start by saying despite my aged condition i have only recently (in the last week) been seduced to the ownership of any sort of mobile phone. I have one that works fine. But in my investigations a friend offered and gave me a XDA exec (O2) mainly to stop me moaning about the silly way text messages are entered with out a Qwerty keyboard. Unfortunately the phone seem to be dead. Or at least in a coma (as it has some life signs).
The symptoms are, White screen, not much else, odd times my eight year old got the keyboard lights on and thats about it, plain white screen. I have investigated the net for answers and tried. Reset (power, back light and reset), taking out battery and replacing, taking out the battery over night, i investigated 02's web site which i found of very little help, the user manual there etc presupposes some sort of information on the screen ! I seized on the idea that a Rom Upgrade might help but all links to that i have found are dead.
I installed Activcync to my PC and the phone syncs up allowing me to see that there is indeed things on it the windows files etc. Which gave me hope that it isn't totally dead.
So any suggestions? can i do anything with this impressive looking paperweight?
Hi,
From your description I would say you have a hardware fault regarding your screen.
Either the cable is broken, not correctly connected or the LCD itself has a defect.
What let's me conclude that is:
- you say you will get a white screen: this means the backlight is working
- you say ActiveSync will recognize the phone and you can browse its contents: this means that the device is working (except for the screen) and that it is not like stuck in the bootloader, or so
- you say your daughter managed to get the keyboard lights on: this means they are working... this, by the way, only happens when the device is in the dark and thats probably why you did not manage to do it yourself
From now, your options are:
- sell the device as broken and get up to 100 Euro on eBay for it
- buy a working Universal at eBay, at prices starting at 140 Euro (better condition will cost more)
or
- get the PDF that explains how to disassemble the device
- check if all cables are properly connected
- check if there is something you can (and know howto) repair
and eventualy
- buy a new display, which will cost 100 Euro or more
So to tell the truth, the easiest option is to actually sell the phone as broken and get a second hand one, which is not broken...
Or get a second hand one (not broken) and keep yours for spare parts.
Cheers,
vma
ah thank you for the step by step reasoning there, i have to agree...
I don't want to sell it, it was given to me and if i cant get it going i'd rather pass it on in the same way.
I will look for the pdf and see if i can confidently have a look inside... many thanks.
A small investigation inside reveals no obviously loose cabled etc.. Oh well!
again many thanks.
I've passed it on to someone who is more electronically knowledgeable than me, i hope he can get it going and use it...

NST Broken Screen, advice sought

I've got a simple touch that got stepped on, now Joseph Conrad has an interesting hairdo (can see where the crack is).
I've got ADB installed and working well for my other (various) Android devices, so using that is an option if I can figure out the Nook side.
The light next to the USB port goes on when I plug the Nook in, so there's some logic working in there.
Questions:
Can someone suggest a way to test if the device is good excepting the screen?
Is it worth replacing the screen on this device and if so, where could I find one?
Assuming screen replacement isn't an option, I'm considering random fun projects for this hardware. Anyone got recommendations?
The first random fun project I'm thinking of would be a WiFi repeater, mostly because I need one in the house here. Total awesomeness would be getting DD-WRT working on it
if u expert in adb ... then u can use and install program named "screenshot" and then run it and take print screen from ur nook and pull pic from ur sd card from screenshot directory .... all that via adb
but i dont know how ... it's just a theory ..... but it will make sure that ur device working or not and is it screen Issue or not
thx
That's a good idea, speedman.
You don't actually have to install any software.
The stock "screenshot" works well enough.
Ok, the colors are all screwed up, but still.
Code:
screenshot /sdcard/snap.png
Oh, yes you can buy screens from NST's gutted for parts.
It just that they cost about as much as a used NST.
If it were mine, I'd do some hacking.
I've already got a console UART connector soldered to the board.
I'd see about expanding the key matrix and seeing if I could get some I/O pins going.
JTAG would be fun to play with.

[Q] Broken Screen Challenge

Hey guys,
So I've been loving the crap out of my nexus 4... that is, until a random stranger on a crowded subway knocked it out of my hands as I was taking it out of my pocket. So the front of the screen is messed up pretty bad glass-wise; the lcd works fine but the digitizer is messed up so I can't use the touchscreen at all.
I'm going to have to shell out on a new screen soon, but I'd like a workaround in the meantime. I figured if I could get a bluetooth mouse connected I could at least navigate around my phone, but of course I need to use the touchscreen to pair with the mouse. Or maybe not, that's why I'm posting.
Can it be done? Through adb or some other means, could I pair a bluetooth mouse without using the phone directly? The only method I could think of might be to pull the bluetooth address config file and insert the MAC address of the mouse into it to potentially trick the phone into thinking it had already paired with it. Does that make sense? Even if it does, I'm most likely going to need some guidance in figuring out how to actually pull it off.
Let me know if it can be done somehow, and thanks! :fingers-crossed:
should have knock the guy out and drop his phone...sound like a fair deal...eye for an eye

Ha ha maybe I would've, but the station was so busy that I couldn't tell who bumped into me... It was on an inclined walkway so the phone actually slid away from me by a few feet, by the time I got it whoever did it was long gone
Click to expand...
Click to collapse
Use the play store webside to load a remote desktop app on it so you can take over it's screen (assuming those apps exist and it's not stuck at the PIN entry screen)
I haven't found any screen sharing/control apps that don't require me to use the phone to generate a code/url, but I'll keep looking
well I figured it out... for future reference you can use the input keyevent lines to navigate around the phone. It's a bit tedious but it's only until I connect it to a bluetooth mouse

ThinkPad Tablet Dock/Charging Fix???

I come to you guys to hopefully get some information. I've been trying to find a way to charge my old ThinkPad Tablet without hoping I with the "charge the tablet long enough to be disappointed" lottery. I know originally the tablet either was designed or was just unable to charge quickly over USB, and I was OK with it, until an update or some other issue caused it to randomly cut out from charging some time after the screen goes off. It seems others have had similar issues when I've researched this in the past.
Unfortunately the tablet is very much off. No way of getting any response beyond a single vibration. No way of getting anything, without hovering over the tablet for more than 40 minutes in the hopes that I can get enough juice without damaging the USB port (which might be... it feels a little loose).
I remember some time ago I had seen people trying to reverse engineer and make some kind of power cable that attaches to the dock but I don't seem to see it anymore, and what I have found seems to have no more pictures regarding what was done or how it was obtained. And I'm willing to just shell out cash for a dock, however that's the next big issue. The dock seems to have vanished off the face of the earth. Sure, places list it once I FINALLY have located the part number, but it's out of stock. Nothing seems to work.
So my questions to you all:
Is there an updated place with the how-to to create a charger of my own? If not, is there any place I can obtain a dock that will work with the tablet? Another lenovo dock I can modify, even if I have to hack it apart (not if the dock connector is unique to the TPT or is something from other lenovo products)? Does anyone have a dock they're willing to provide to me for a reasonable
price?
...Do I have a $450ish brick of a birthday gift from a few years back?
I missed using it. It wasn't perfect but it was, at the time a great tablet for me. And I've been itching to clean it up and see what I can do to hack/modify the tablet/android/whatever... but I can't right now, while it's effectively a paperweight...
Anything? I really am hoping someone has some kind of information I can use. Somewhere I can buy stuff, or a good link with details on building/hacking together a cable/dock...
