Hello Devs, OP fans, lurkers alike
So I've had quite the quirky experience recently. Thought I had a brick in my hand for a while. Then strangeness.
Last week, I left my phone on top the car after gassing up. Half mile down the road, it slides off. My music from BT goes out. I return to find the screen smashed, display black and unresponsive.
Back inside the car, BT connects immediately and my song picks up right where it stopped. The capacitive hardware still works, vibrates when I tap or hold the BackHomeRecent, turns the "screen" off when I hold home.(or at least Android thinks its turning off).
So I decided to replace the screen and digitizer assembly with a new one. After transferring all the components as per a 50 step procedure found on ifixit, I go to power on. Nothing. No lights, motorcars, not a single luxury.
Maybe charging will help? AC USB yeilds nothing. But then my pc recognized it as USB Bulk 9008. At this point, I'm just about to give up and go buy another phone, figured its Bricked enough for me.
An hour later, my Android alarm clock for work goes off. Screen still black, but the led lit up. I had to pry it open and remove a screw to detach the battery connector to shut it up.
Obviously Android still works. Defective replacement screen, perhaps? Maybe I Fudded the reinstallation Elmer style? Is there hope to save my device?
PS. Dev Options were off during the accident, PC didn't even recognize anything while it had its cracked screen.

I was on my computer when i remembered i has something written in my tablet's notes that was important. I took it out of my bag and noticed it wouldn't turn on, it was out of battery (hadn't touched it for about a week). I just plugged it in the proper asus charger and put it down and went straight back on my computer.
I decide to check on it after 2 hours thinking it would be near or fully charged. I pick it up and noticed it was on a blank back lit screen. I unplugged it and then the screen turned straight off. Wondering if it didn't charge at all i re-plugged it in. There was no google logo (rooted), instead it turn on with a lit black screen and off and repeating a few times and then small thin artifact pixels run across the screen (red, blue and yellowy colours) and then stay at a black lit screen like when i first picked it up. I had just noticed a small buzzing sound while this was happening and still does so when stuck at the screen. I'm pretty sure it was buzzing when i had found it.
I redid what i had done (unplug, replug) and watch to see if it did the same thing. It did. I tried to power it off while it was at the black screen and it did, but then it would turn back on and etc. Same if i tried to enter boot loader or any key combinations.
I've tried disconnecting the battery and reconnecting and same effect (tried it without battery attached also)
I have a feeling it is dead now and i have no other ideas (checked many forums but got nothing).
Any help would be appreciated.

It's surely hardware failure, have take some humidity or something like that?
Try press power for 60 seconds, if you wont see any Google logo there's some hardware failure you need to RMA ( http://en.wikipedia.org/wiki/Return_merchandise_authorization )
found the fix
I found away to fix my nexus 7. You could be right how it might have a minor hardware fault, live in australia in the high hot tropics (high humidity). I decide just to plug it into my computer usb charger instead of the proper charger since it had a lower max amp output. Against my ear, a much fainter buzzing is still heard but this time, there was nothing. No power, no back lit black screen, just a very faint buzzing. Decided to let it sit just to see what happens. After an hour or so, i decided to press the power button and noticed there was a battery charging signal. To my delight, I'm sure it was in working order now so i powered it on and oh how relieved i was.
I determined that my device might have had a small hardware fault that made it draw to much power from the 2 amp original charger and thus why the tablet could not boot up properly (from battery depletion). Either that or my charger could be bugged to. But the thing is, since it charged to slow from the usb, i plugged in the proper charger and it worked fine. Just have to try not deplete my battery i guess.
Thanks.
Hi, I bought a G2 (Verizon model) off eBay with a cracked screen. When it arrived I plugged it in to see if it would boot, it had a red LED come on and windows made a USB noise but nothing was displayed on the screen. I waited a few minutes and tried to turn it on. It said it was on 4% battery and not enough power to boot. Fair enough, seems to be working. I unplugged it and took it apart then transplanted the parts into a new LCD I got from aliexpress. Was a pain in the ass, that glue and tape is tough to fight with but I finally managed to wrangle free all the parts and get them over.
Put the phone back together and now when I plug in the USB cable there is no LED and no USB noise. I'm sure I plugged all of the parts back in. I don't know what a part at the bottom near the charger is though, could it be as simple as this part being responsible?
Here is an album of my phone if anyone can spot anything I missed

Please help if you can
Phone will turn off if I tap on the blue dot shown in the picture. I can not turn it back on unless a charger is plugged in. After it is on, it will stay on without the charger plugged in. It will sometimes turn off when in pocket or face down on table, but I have consistently been able to cause it to turn off when putting a little pressure on the blue dot. Any idea on what is under there that could be causing this?
I grabbed a screenshot from a teardown video. See the attached picture.
As you can see on the screenshot from Luniz2k1 it could be the battry, cable or something other on the board. While you press on the blue area it bends the whole cover so the force will be transferred to other components too, not only on that single point. If you don't have warranty just open it and, maybe try again pressing on that point with an plastic tool.
I'll give it a shot, hopefully it is not too hard to open up. Thanks everyone!
Wow, how surreal. I had the very same issue with a Moto G4 Plus that I bought during that major discount Motorola was offering on their site on Thanksgiving, down to the letter. I just RMA'd it since I had recieved it like a week or so later and found that nobody online had the same issue.
My theory is that there might be something shorting out as you pressed down. There's not much else that comes to mind as to why the entire phone could shut down.
Have you managed to fix it by yourself?
Unfortunately not yet, but as long as I baby it it will stay on. I keep a pocket juice and us at all times in case the phone needs a jumstart
you may try to check the wire....if by pushing wire it get turn off then there is the problem in battery wire....then you need to change it..
Unfortunately my 5 month old phone dropped into water and stopped working :crying:. After much research, I have successfully opened up the phone following this excellent demo without causing any damage to the screen and body.
As shown in the pictures below there are rust near the connection slot between screen and the mother board. Actually that is the only place I've notice any visual anomaly. After thoroughly dissemble everything from the mother board and clear all the rust with 99% alcohol then putting them back together, I'm still stuck on the following status:
- When disconnected from wall charger, and long press the power button, the LED lights had a very brief green flash, then went dark. After that when I touch the finger reader in the back, the machine vibrate as if it is trying to read the finger print, but the screen stay black (dead).
- When connected with the wall charger, the LED first show flashing red light for about one minute, then stay solid red for another few minutes, then turn off. Again, the finger print reader is responsive to touch, but the screen still stay dead.
- Finally, when connected with the 360 camera, the camera lights up and the internal fan also spin up, making me believe that the phone battery could be functional.
I tried pressing down power + volume down/up buttons simultaneously for 30 seconds to enter the bootloader, but the symptom stay the same, the screen remains dead.
I've also purchased a brand new screen replacement from a reliable vendor and tested it on the phone, still the same symptom. So I assume it is not the screen issue.
At this point, I would appreciate any help in:
1. Diagnostic. What does the 1-flash green light, flashing red light and solid red light means? Does the fact that finger print reader vibrate upon touch tell anything about what's working and what's not?
2. Other way to check the battery?
3. If I want to purchase a motherboard, given that I'm on AT&T, does the replacement need to come from another AT&T phone? I found one on Ebay where the seller mentioned the IMEI is clear but carrier is unverified. How does the comparability work?
Thank you for your help!
Hi! I would like to help you with this problem. First we would need a better picture of the motherboard, where the damage as been created. (Screen port)
Second, you could always give a call to Essential, I think they offer a replacement for 200$? Still cheaper than a new phone and don't worry about purchasing a phone that doesn't come from AT&T, I have the Telus model and it's the same as every other essential phone on the market.
Hi all-
My MZF went for a swim a couple weeks back. Put it in a bag with some DO NOT EAT desiccant packets for a few days, actually got it to turn back on, except the Power Button didn't work and the camera crashed every time I tried to open it.
I replaced the camera module and volume rocker/power strip with OEM used parts from eBay. Phone came back on, power button and camera worked, and everything actually seemed good until I plugged the phone in to charge.
I came back a little while later and the screen is black. Phone still vibrated on fingerprint touch, and when trying to power up/down with the power button. Did not come back on reboot, and every so often can see a very brief flash on the screen. No sound either. Thinking I somehow fried the display when I plugged it back in. Thinking about getting a replacement, but all the used ones on eBay are scratchy and/or burned in, and all the "new" "OEM" ones just seem shady.
Anybody ever done anything like this? Looking for any insight!

I replaced the display on my son's a couple months ago. Went well and looks great, but from your description, I'm leaning more towards a bad battery or charger port.
Thanks, appreciate your post! It was charging properly and holding a charge before I dismantled the thing, so I don't think it's the port or the battery. (Granted I could have screwed it up by doing so.) While the screen is still dead, it does vibrate when I press the power button or do a hard restart (hold all three buttons), as well as if I touch the fingerprint scanner after letting it sit for a few minutes. Which makes me think it's booting up into the OS just fine, I just can't see it. Have an OEM display on its way from eBay, hopefully it will do the trick! I'll let you know!
