Hey guys.
Basically I've recently replaced my whole screen assembly on my Nexus, but it turns off after a few seconds when it's not on charge.
Sometimes it'll last about a minute but will instantly turn off. I've tried a factory reset and it still does the same thing.
I've bought a replacement battery, just making sure that there's nothing else wrong with the phone? any advice etc would be appreciated.
Thanks.
If it started after you replaced the screen, then its likely that something isn't seated properly on the inside. I changed my screen too, so have a look at the battery connector and the connector that connects the bottom board (the one with the charger port) to the top one.

It was doing it before I changed the screen.

In that case it probably is the battery. New one should fix it.

I replaced the screen and digitizer but when I tried to power up, nothing happens. I thought it was a low battery issue so I left it charge overnight. Still nothing. I put this battery into another Nexus 7 to see if it is a battery problem. That Nexus booted up and shows the battery at 100%. So the battery did charge as it should. I tried putting the battery from the second Nexus into the first Nexus and It does nothing. I have checked all of my connections several times and everything seems to be fine. It did power up before I replaced the screen and digitizer.Any ideas?

This might be a hike but try using the old digitizer. It's very possible you have a bad digitizer since the battery charged full.
I tossed the old screen and digitizer already.
Its possible it has turned on but the screen isn't working try plugging into a computer and see if it recognises anything

OK if you have two nexus try swapping the motherboard over try not to bend the springs on the mb for the circuits on the back they are made of phosphor bronze and break easily

That's going to be my week-end project. The "good" N7 is one I use every day.
One thing I would like to add. When I was charging the battery, I did not have the back cover on completely and I could faintly a voice saying "alert". When I snapped the cover back on I could no longer hear it and it charged. Does that "alert" mean anything?

I've never heard of that before. The nexus should function without the back although WiFi NFC and Bluetooth won't work as the antenna's are attached to the back

I did get my laptop to recognize the N7.
I got a new LCD flex cable and still nothing.
I put the new S/D into my working N7 and all I get is a screen that is half black on left side and half on right side looks like the backlight is on and nothing else. So is the S/D defective?

Sounds like the screen/digitizer is defective. Return it for a refund or exchange.

Weird problem but my phone has a screen that shows a distorted display or sometimes just speckles of random color. It seems the problem mainly occurs when the phone has a SIM in, gets hot, or maybe humid.
I ran stress tests on CPU and GPU for hours with no sim and it worked perfect. Then I put the sim in and later the display went crazy (this is not a touch screen issue). Then I took sim out and it went back to normal. I thought I fixed it by blowing out sim slot, but then the problem reoccurred. I had to take off back of phone (while it was on) and it was immediately rectified. It makes me think that something is getting pressed down too hard. I tried disconnecting the video cable and reconnecting it to see if that will fix it, but this particular phone has not been opened since the factory so it seems weird that it would suddenly get a loose cable.
Any ideas appreciated. I would like to fix it.

Had this issues after replacing my display!
Antenna cable is near the display eletronic parts in the lower part of the phone, near the usb connector, you've to put a tape on the eletronic, or you'll ever have this interferences when you use the antenna! (Antenna is the grey cable), display elettronic parts are a little square, betwen battery and USB connector, and have the grey antenna cable on them beacouse the antenna connector is near in this part of the phone! Sorry for my bad english, hope this help you!

I haven't replaced the screen on this phone, but when I took off the bottom piece the connector just fell of lower control board. I snapped it back in and we will see. Maybe it simply got loosened somehow by shaking etc... Hopefully that rectifies the issue. Thanks. I was going to swap the lower board (I already swapped upper one) but maybe I can avoid that now.

Can you post a photo taken by other phone (not a screenshot from your G2) showing your G2's current problem?

It was the lower connector like was said earlier in the post. I had already swapped the upper board with the other phone and the problem continued, when I went to mess with the lower board the connector was loose and upon tightening it down it started to work. I have had an instant of glitch two times in the long period since then, but it goes away immediately. It seems the connector need glued down or something who knows. I am happy though it is working well enough to last me until something comes along that makes me want a new phone.
I don't know if this is the right section, anyway because it isn't specifically hardware related I posted here... for admins feel free to move in the appropriate thread.
My G2 dropped on the floor and as result I got a complete broken display plus not working touch.
The device, touch apart, worked without issues so as 1st step I made a full backup of sd-like content (music, pictures, etc...) to my laptop.
note: even if touch didn't work I was able to access the device trough adb and a very useful utility (http://marian.schedenig.name/2014/07/03/remote-control-your-android-phone-through-adb/)
Next I ordered a replacement for the display, looked for instructions and changed by myself... and the phone didn't boot or even charge... nothing, the only signal of life was when attached to the wall charger the led blinking in red eight (8) times consecutively then no blink for a second and again blink for 8 times and so on in an infinite loop.
Of course I started to look for solution and tried every kind of combination but none worked.
I started to think that I missed up something during the display replacement or the battery fault or even I fried in some way the motherboard, anyway for what I read it supposed that could be that the battery gone under certain voltage or minimal charge so the motherboard circuit didn't recognize as "good or safe battery", it is simply bypassed by charge circuit.
note: I waited for the new display about 10 days and the device (fully charged) slept (turned off) in a drawer so I don't think it was totally discharged
I disassembled and reassembled again the device but nothing happened so while looking for a solution I saw a video on Youtube (https://www.youtube.com/watch?v=MZwknmWCmOE) solving a issue similar to mine so as instructions I took an old charger (800ma), cut the charger connector and exposed the 2 internal wires (one red and the other gray/black).
Then I opened the device, disconnected the battery and attached directly into the battery connector the two charger wires (in this way mobile motherboard is bypassed).
I used a small piece of tape to stop and make touch laterally the 2 wires to the connector, something like: dark wire -> [ battery connector] <- red wire
Keep in mind that the connector is something very small like (0) where left parenthesis is for dark wire and right parenthesis for the red one.
note: you can't wrong with wires, because the positive (on the battery connector) has a small white triangle.
Of course I found a way to don't move/mess wires before connecting the wall charger... I put another piece of tape at 20cm on the table to keep the cable charger fixed near the phone, then I attached the wall charger...
remember: attach the charger to the wall ONLY when you have finished to place/fix the contacts!
Waited just 1 minute because exposed charger wires was very close and didn't want to fry something... but it was enough!!
Reconnected the battery and voilà the phone turned on!
The phone turned on with almost 80% of charge, all seemed to work... except that I found 2 issues... I suppose because the case didn't match perfectly anymore (I opened the device 4 times and disassembled-reassembled twice)
1st speaker didn't work, so I reopened the device and checked the speaker connector, I discovered that the speaker didn't touch very well so I put a small stripe of tape under the connector (the small vertical green stripe in the lower side of the phone) to lift it and making touch stronger with the speaker module (the black part the come out), here on Youtube for reference: https://www.youtube.com/watch?v=XE2FPmFUrQQ
2nd GPS didn't work very well (discovered after a couple of days) so I reopened the device and applied this solution that worked perfectly: https://www.youtube.com/watch?v=dfS4LpfcLfg
This is my story in the hope to help someone, if you have apparently a total dead phone and the only signal of life is a 8 times blinking red light... now you know what to do!
Regards,
Davide
Thank u for share your story
Congrats on fixing your problem!

You mentioned the alignment of the phone wasn't the same as before....
Did your battery swell or change shape at all during this process?
If so could be a sign its on its way out and needs replacement.
A dying G2 lithium ion battery changes physical shape and completely alters the internal alignment of your components.
May be worth an extra 10.00 to replace your battery at this point with a new one

thank you, I was a bit frustrated because I thought to have broken the motherboard, even if it wasn't very easy I didn't surrend and I won!

I understand what you mean but no I don't think so... it seemed the same size
anyway battery has less than 1 year of life and never showed symptoms or bad behavior, right now is running as before... I can pass easily 24h without recharge

Have you found the source of your alignment being off?

I checked and found nothing in particular... just a bit near the sim "area", but it seems just a sort of plastic adaptation... as mentioned before I opened, disassembled, reassembled and then closed it 4-5 times (in just few days)
Please for advice! I had to replace the motherboard on my G2 D802, I think everything done correctly. After turning the phone on, the display remained black and refused to turn anymore. I put the old board with that previously loaded, but now it is the same result. I asked friend and took his board and ribbon cable (kit) - Alas, the result is the same, namely: pressing the power button, the phone vibrate briefly flashes the upper led diode green and blue - the screen is black. When is connected with the PC being recognized, even updating software in this state. I think the display has a problem or his ribbon cables .... I do not understand much. I hope someone advise me what I can do or where to read !!
Thanks in advance !
It's very possible that the ribbon cable broke if you weren't careful. If that's the case then it's not something you can fix and you would need a new screen. It could also be that you aren't seating all of the connections properly. Take it apart again and note ALL of the connector locations. While you're in there, VERY CLOSELY inspect every millimeter of the pcb and ribbon cables for damage. If you don't see anything, carefully reassemble it being sure to squarely lines up the ribbon cables before firmly seating them(you can mess up the whole board if you press on them too hard if they're askew).
I reviewed the cable but nothing impressed me. Because I am the second owner, assume that it is possible to display is not original, but some cheap fake. Is it possible this option ?? Attached pictures:

From the pics, that display does not look like it's fake. The letters and cable itself looks to be identical to the one I took out when replacing my screen. If it worked fine before taking it apart, it should still work with the new logic board.
Btw, when I was replacing my screen I didn't correctly seat one of the two ribbon cables that go across the battery and my display was also black even though the display cable itself was correctly installed. After taking it apart again and methodically taking note of every connector on both sides of everything and very carefully putting it back together, it fired right up. That's why I said to check EVERYTHING - it doesn't necessarily have to be the display/cable.
Good luck.
I'm unsure if I'm having the same problem as a person who decided to replace his screen assembly had, but I'm in a situation where I can't tell if it's a software issue or a hardware one.
I've checked the cable under the battery and everything looks great, it even reseats just fine. the other ribbons are plugged in just fine...
I'm not sure where to begin, please help!
Any thoughts at all? I banged my head against a wall all night!

I can't imagine it would be software if it was working before you took it apart. My first thought would be dinged ribbon cable under the battery of course but you said its fine. You could check terminals on motherboard and ribbon cable with a magnifying glass or camera on zoom mode to make sure nothing got bent and no debris got into the connection when reassembling. Not the first time I've seen someone damage the display when replacing a battery on this forum unfortunately. There's a few cases of this in the oem battery thread.

Sure does look fine. The only thing I notice is the debris or whatever it is on the solder pads halfway down the left hand side in the motherboard picture, it's in two spots. I wish you luck.
Nope! nothing
Mine had a problem of a pink hue after the battery replacement I did, I'm pretty sure it's because I separated the screen and LCD a little at one time..oh well least it don't die randomly

Sooo I got another (Broken) nexus 6p for $30 off ebay and swaped the motherboards. I plugged it in and got a red flashing light - I then replaced the battery with my new one and all that happens is when I plug it in I feel a vibrate. I try to turn it on and it vibrates... exactly like the problem I had before. Ugh, it must be the socket (? I think that would be the term) and not the screen. hm.

The phone you bought had a bad motherboard and good screen assembly? Anything come on screen if you hold power and volume down buttons simultaneously for 5+ seconds? Or hold volume down while plugging it into a computer. Any joy if you install your original battery from original 6p? Kind of lost without being able to see it. Just throwing out some ideas.
I have your same problem... did you solve it?
