Motherboard swap? - Nexus 4 Q&A, Help & Troubleshooting

Recently cracked the screen on my n4. After looking around for a screen replacement without success I decided to buy a new n4.
I was unable to recover my data - photos videos etc. as I had a lock screen pattern and was unrooted.
So question is can I just transfer the mainboard from my old n4 to the new one without any issues?
All I want to do is get my data from the old then put the new back in.
Any help is appreciated. Cheers

G1 Has Lines on the Screen -Searched already

Hey guys i searched these forums and i searched on google, couldn't find any information. I dropped my phone today from less than 1 foot and it turned off and when i tried turning it on my entire screen was white except for the top which had black lines and you could tell the phone was responsive because of the way the lines moved. What do you guys suggest i do? I can't figure out a way to make my screen work normally.
Your screen is broken, simple as that. Time to get a replacement!
Where exactly do i get one? And what is the part called which i need to replace? My phone doesnt even barely have scratches and my screen stopped working -.-. I hate my life.

Ummm... T-mobile would be a great place to start... Just tell them it stopped working. Unless you bought it off warranty or without insurance, then you can buy it or any part for it where ever you can find it.
Yeah, no warrenty on it. What is the part called though i have no idea what the screen part is called so i can order the part.
bump. anyone?
You might need an LCD replacement part for the G1 if it is damaged... Other possibles could be the ribbon cable somehow got dislodged/damaged so you're not getting an image. Can you still make calls from it?
Yes it receives calls, its just the screen. would this be the replacement? http://cgi.ebay.com/OEM-LCD-Screen-...ries?hash=item43994d9bc5&_trksid=p3286.c0.m14
bumping for help

[Q] Nexus 4 with broken (fullly black) screen and no USB Debugging

Hello xda-developers forum,
I realize this has been asked before, and I've read through many threads here and elsewhere, but I'm not getting a definitive solution that works for this particular situation.
Here are the details:
Phone Model/Make: Google Nexus 4
Carrier: Wind Mobile (Canada)
Screen is cracked/broken, completely black.
USB debugging is not enabled.
Completely stock ROM, have not made any customizations to the phone.
I have adb set up on my laptop, but don't know how to proceed in terms of loading into bootloader (?) and flashing, pulling data, etc.
Mostly only need to retrieve photos and videos. Already synced with Google for contacts (but not photos, unfortunately).
If you need more information, please let me know.
Is there any way I could retrieve the photos or are the precious memories lost forever?
Thanks in advance!
I dont know what cause you that problem.
but i suggest you to install driver on the computer and with tool box install stock rom in your phone.

Installing stock ROM would wipe his device, if he were able to, which he obviously can't.

A new screen should work, as long as that's the only thing that's damaged. It's up to you whether it's worth the $45 for a new screen assembly or $60 for the entire front unit (less frustration and possibility of screwing up than just the screen assembly) to save the photos on your phone. Those are USD amounts - I don't know how that translates into Canadian or if shipping will be extra. Swapping screen assemblies on the Nexus 4 is actually fairly easy - especially if you buy the assembly already installed with the bezel. I've done it myself probably 20+ times trying to get mine to work (I eventually did). There's plenty of teardown guides and videos on youtube on how to do it. Get yourself a new battery while you're at it, for $20. Maybe you've already replaced your phone, but either way you can get practically a new phone for $45-80 depending on what you want to replace, or a cheap back-up (always good to have) for whatever you've replaced it with. Plus all your precious memories back.
You cannot unlock the bootloader without losing everything so your best option to restore important data is to replace the screen. The battery is glued pretty hard to a breakable piece so watch one of the YouTube videos and decide what all you want to replace. Ifixit had a good video that I used when I had to replace the logic board in mine.

[Q] Broken Screen on my Nexus 4

Hello,
I dropped my Nexus 4 (EG960) couple of months ago, ordered a new LCD + Digitizer and started to replace the screen myself.
Everything went just smoothly, I removed the broken screen, put the new one, put everything back together, slowly and safely connected all components, turned on the phone and.................
Guess what? The phone is turning on, but I can only see stripes of different colors all over the screen. I can see that the Google animation is working in the background and that the phone successfully booted. I can actually still see a line where the previous crack was.
I tried reassembling and reassembling everything slowly but still see the issue.
I can attach a picture if needed.
Am I missing anything?????
Thanks,
Liran.

Well it's great and all that you took apart and put back together but I'm not a big fan of repairing screens, digi,etc I think no matter who fixes it will never be the same as before if you could I would try to sell it and just get another one.. Or take it to a professional and try to get a warranty with repair.. Just a thought..
Sent from my Nexus 4 using XDA Free mobile app
And still I did, and wonder what to do next. If to try and replace other components or just give up.
Option 1 is more suited to me.
Thanks a lot
Same thing
Does anyone know a solution to this problem? I replace the screen, the same problem.

We can just guess.. Maybe you damaged a flex cable or a connector/plug. If the problem persists with a second screen then I think its something on the mainboard as suggested..
maybe this helps?

A truck rolled over my ZenFone II - ZE551 ML [BACK/SOUND/CAMERA SEEM INTACT]

Hello peeps,
I had just recently got this phone, its been 2 months exact and yesterday this happened. It was upside down when it rolled over it (was on the road), I was surprised to know that its back merely seems damaged (see pictures to have better idea).
- Speaker seems to be working fine. (SIM working in it!)
- LED indicator is blinking too and working as it should.
- It turns on/off without any problem.
- The power and volume buttons are also working fine.
I had lock screen passcode on so can't access the data, but it connects to computer fine. I wonder if replacing the display and screen digitizer will be the only things I need to make it work.
PS : I had no screen protector/back case or anything on it.
EDIT 1 : Touch is still working. I just somehow like entered the emergency mode and I can hear the dial pad tones.
EDIT 2: Data accessed!!

I just disassembled it, apart from one thing everything in there seems intact, it may require soldering.

Don't think a tempered glass would've saved his phone from a truck lol. I'm impressed by how little damage it took actually
Please keep us informed if you find any damage other than the screen and back.
Wow sorry about that but also glad to see how it was able to withstand a beating like that :banghead:
Make a youtube video. It might go viral if you can show it still works ie: sound phone call. You might make enough money to buy a new phone.

If you had usb debugging enabled, you can completely remove the lockscreen and access your data. There is a reddit post detailing how to do it step by step. Please Google because I don't have a bookmark. I did this to my Z3 when i got damaged. If you didn't have USB debugging enabled, you'll have to find some hack to do that before attempting.
Also replacing the screen and maybe the digitizer (if damaged) should get your phone back up and running.

Hey if USB debugging was not enabled, you might have to find a way to do it. And I did try doing some Google search but couldn't come across anything! Really sorry but the thread was on Reddit and you should probably search for it there. I'm not sure of the exact keywords I used!
Touch is still working. I just somehow like entered the emergency mode and I can hear the dial pad tones. I can try entering the pattern now, but I don't remember if I had to like swipe after pressing the power button or double tapping the screen or it was just the code straight away after pressing the power button or tapping the screen, could someone please help me with the two options as how they work and also just send screenshot of the lock screen with pass code on so I have the idea about it and all?
EDIT : @thedisturbedone : I managed to pull the lock away as touch screen is working haha!
Is there anyway possible that I can use it via PC? Asus PC link requires the app running in background. Also anyway possible to backup the contacts now?
@ASUS_Khang : Have a look here.

Hey there, thanks for sharing...been away on Thanksgiving. You want to save your data? Hmm...good question. Here's what I would try to do:
- Contacts should be backed up in Google - so no worries there...you can access via. http://contacts.google.com I think
- Connect the phone to PC, Install ASUS PC Link. You should have the app running on the phone.
- I would then try to drag all the files you need to your computer,
- Or the other thing you can do is if the information is crucial....And I don't promote doing this, and this is not an official ASUS fix...because you will void your warranty..sooo anything issue that happens is on you and ASUS will not help you if something goes wrong...is to root your device, install Titanium Backup, and use that to save all your data (apps and everything) into Google Drive, or Dropbox. Then, you can restore that data back to your phone when it's fixed.
What about micro USB to HDMI and then follow on the big screen what you're doing?
@ASUS_Khang : I wanted to have your attention for the giveaway thing as my story is all posted here. Thanks for the input anyway.

I have recovered the data from the phone itself, the remaining things are notes/contacts which I can't do via connecting the phone to PC now and I had backed up contacts already so no worries.
Haven't read the whole thread, not sure what your plans are, but thought I'd share a recent experience.
My wife knocked her phone off a table at a restaurant a few weeks ago. Landed on the corner when it hit the tile floor. Screen shattered. Was still usable, but bits of glass were flaking off.
I ordered her a new screen & digitizer from amazon. Took about 3 weeks to show up. I replaced it using a plastic spudger tool I had from an old iPhone screen replacement kit, and some patience. The screen replacement kit I ordered came with some double sided tape to reseal everything. Took about 90 minutes to complete as I was taking my time. The replacement went flawlessly and you can't even tell her screen has been replaced. I'd recommend trying that before replacing the phone, unless you want to.

Seeking help extracting phone contacts from a broken phone.

Alright, long story short... I've been a user of a D-802 for the last 4 years. I was unlucky enough for the phone to be dropped from 2nd floor at work (don't ask how), the panel housing the screen is bent in right upper corner, which ultimately means this; I've fixed the screen two times, for it to be broken in less than half a month. Even more so, I ordered a new screen a week ago and it broke because of the bent frame 10 minutes after fitting the screen, as in, simply putting on the rear plastic cover, which broke the screen and the flex cable. Took it over to a repair store, they told me the phone has a broken cable on the screen and a new screen costs 90 EUR (not really worth considering how old the phone is.) and the motherboard was damp, too.
Now what I've got is a glorified brick. It turns on, the screen is black/non responsive to touch and it's stuck in file transfer or charging mode. Not really a problem, as I was able to retrieve all the photos from the phone through USB connection, however, what I'm really after are the phone contacts in there. We're talking about 3+ year old contacts that have a monumental value to me and I'd see gladly see them backed up.
Now, the reason I hadn't backed the phone is because it's rooted, obviously.
Out of ideas so far, will be eternally grateful to anyone with suggestions.

I think the easiest way is the same way you rescued your photos from internal storage. Search the system partition for database files like contacts.db or other *.db-files. One should contain your contacts.
Good luck! :good:
Thanks, but no luck on that behalf. Already tried that, also didn't find much luck with adb or other software, as it all requests USB debugging to be turned on.
