I replaced successfully my display. As soon as I close it (putting back and front part of case together) my phone shuts down immediately and booting is not possible anymore. When plugged to the charger the LED is blinking (white). So I switched back to my old display only to observed the same behaviour. Without the back part of my case both displays are working and I can boot the system. Also my phone is working when connected to a charger without any battery attached.
Anybody has a clue how can I close my case without ending up in the EDL mode? Should I replace the battery? Currently my battery is only 80% charged!
EDIT: I manage it to close the whole case. By doing it really careful and slow. But after I reboot or shut down the phone. Same behaviour cannot boot and plugged to a charger the LED is blinking! I have to reopen the case to boot my phone.
EDIT (2): After a while my phone is shutting down to restart it I have to take off the back part of my case, plug my phone to the charger and then boot untill system starts. After that I can close it carefully again.
Just suggesting the generic things in case you missed them:
Check if you're shorting out something. You might also be putting too much pressure on certain components when you close it up -- align properly. Check that your ZIF and flex cables don't misalign when you reassemble the phone.
I'm not familiar with our A1's LCD -- but you may have used too much or too thick glue causing more pressure than normal.

Hello,
This is a message in a bottle : my phone has just decided to jump out of my pocket straight to the ground (nearly 80 cm), and now it simply refuses to start.
The screen itself is not broken, the device looks ok, but it does not start.
When I remove the battery and plug the power cord, the red light is on, but when I do the same with the battery inside, the red led remains off.
I have also tried to reset, hard reset, removed the SIM and plug the cord, etc, with no success.
If you have an idea, I'll welcome it.
I can't figure out what can be wrong : there is no mobile part in the phone right ?
Thanks for your support
Gaofi

you probably cracked the Mother board or shook loose a solder joint. will it take a firmware or go into bootloader. could it just be your screen try to turn it on then wait and se if it will activesync this will tell you if your screen is broken
Now when I plug it into the charger, it just goes to the Core Cell splash screen, for like a split second then turns off, then does it repeatedly... I donnu, how to charge my phone, I donnu what to do, please help.
like i ttly hope someone can halp...i donnu wut it iz.
i wuz in yor phonez checking ur batterys, and it looked mkay to meh.
lol.
I don't know WTF is going on here... My phone is like constantly just reloading the same thing, every 4 seconds, it just loads the Splash screen for less than a second, turns off, then does it again, this is while it's plugged into the charger, when it's taken off the charger, nothing happens, I can't ever turn the phone on...
You've obviously got a bad phone.....take it in to your local store T-mobile and have them look at it.
Have you tried plugging your phone into the computer to try syncing/charging it that way, or just into the wall?
I tried the computer, that takes longer to get the splash screen to come up, & there is no T-mobile in Australia, plus I don't have a stock rom, and HSPL.
Try taking your battery out and making sure that none of the pins that make contact with the battery are bent or broken. It is easy to bend the pins and it can prevent charging of the battery.
Another option may be to hold the volume down button during this startup loop and see if you can get into the bootloader. It should charge in the bootloader and it may stop the looping. After charging for a while just restart and all should be well.
I have also had this and other strange things happen when the battery is depleted or very low. I try to not get below 10% anymore just in case.

I fixed the issue last night, I chucked my Battery into the Freezer, for like... more than 8 hours, woke up, and plugged my phone back together, and it charged, without booting up and restart
So all good
Obviously, your battery was terrified by what happenned to the chicken and the turkey in your freezer and decided to behave!
I really don't think it's a good idea to put a freezing cold battery into a warm handset.....that's a recipe for condensation and rust and/or water damage.
I was running Android ICS for a while, and all went great. My brother used the phone and it had some trouble, so I needed to reinstall. I rebooted, tried to get to recovery, failed to push the buttons on time, and it went on booting normally. I then removed the battery to restart faster again. I putted the battery back in, and the phone wouldn't react anymore, no power on, no charging, no nothing.
It worked great, but is it bricked now?? Is there anything I can do?
Turns out that there was something wrong with the battery connectors. Fiddling around with them suddenly made it poweron again.
they bend very easily, it happens a lot, and the first response to 'suddenly wont power on' is always check the battery pins.
my phone did not power on before because the bad pin too.
This happened to me once and i thought i bricked my phone. Turns out you need to make sure the metal connectors on the phone are tucked in and touching the metal pads on the battery.
IT ALL STARTED when my wife dropped phone and cracked the screen slightly and touch in some areas stopped worked.
Me being a technical person, went ahead and bought an lg g2 lcd+digitizer replacement off ebay and made sure it was OEM and had the LG logo on it. The phone is an ATT phone by the way and made sure it was for D800.
The part arrived and I went on my merrily way to replace it VERY CAREFULLY. The screen fit in perfectly and I reassembled everything carefully, connector by connector screw by screw.
When the time came to turn it on, it actually turned on and booted normally and the screen worked, the touch worked (altough some letters on the keyboard were douple/triple tapping,etc.) I ignored that and ran into a problem where when being on a call, the screen turns black as normal, but won't turn back on at all until a hard reboot is done. I went out and researched that this was the proximity sensor malfunctioning and that the replacement screens do not come with some sort of grommet that holds it close to the screen and blocks peripheral light. Well, I was annoyed, and went ahead and opened it again to see If I can remedy the proximity problem.
After some adjustments by the proximity and reassembling the phone, it booted up. I saw the LG logo, followed by the ATT startup chime and then, poof. All dark!! So what follows is a succession of fail after fail to try to get it back up and running:
-reopened phone, reseated connectors, nothing, same problem
-reopened phone, found that i hadn't routed the antenna wire correctly and that it had some metal part in between the wire that may need to be making contact with the metal on the frame. Still nothing, same problem.
-a bunch of hard resets, same problem.
-Try to go into restore mode, clicked yes on restore. Even worse after restore all I get to is the lg logo.
-As a last resort, went into download mode by plugging in USB to computer and phone, holding UP vol button. It went into 'download mode' and I went ahead and followed instructions on restoring the factory firmware flash. The process was 15 percent complete when it died, shut off.
-tried the flash process one more time and it went to 22 percent and died.
-knowing it's a hardware thing, I reopened phone and triple checked everything again. After reassembly, phone is TOTAL BRICK. No power, no LG logo, with usb charger and power outlet charger. No restore mode, no download mode, NOTHING NOTHING. Last known battery level was 13 percent when I was doing firmware flash attempt.
WHAT IN THE WORLD IS WRONG. Any experts know what I can check at all?
I managed to revive the power some how by disconnecting battery ribbon cable and holding power button to drain residual charge followed by reconnecting battery cable and plugging in charger.
I started the firmware flash and it failed at 8 percent because phone shut off. I swear to god..
nevermind. After the last post it wouldn't start again, disassembled, and basically found that the lcd ribbon cable connector pins were jammed beyond use. I'm pretty sure this wasn't the problem though in the first few times I opened it because screen worked fine. I disassembled more and found that the super glue I used totally burned into a small portion of the frame where the back of the lcd sits on as if it were some kind of acid or something. These may have been the culprits but I still think there was something else going on. If it hadn't been for that piece of **** proximity sensor this wouldn't have happen. The phone is a total loss and threw it in the trash. Done, RIP.

Thought you were going to say wife haha. Sorry to hear about your phone, just don't go giving your phone to your wife anymore . Thanks for sharing your sad story .
Have had the phone for a while now but for some reason recently the phone will randomly shut off. Some times it will immediately start booting back up but more often then not it will just stay black. holding the power button does not turn it back on and some times even holding the power down and the power button doesn't work I just have to wait. I'm not sure whats going on.
The problem is this most recent time it did this and the light was solid blue. after a while a green light started to flash slowly while the blue was still illuminated but the phone would not power on no matter what I tried. I took the back glass off and got to the battery plug and unplugged it (thinking that it was just a hard freeze) now i have no lights and I can't power it on. I don't even get a battery or any lights when I plug the power in.
Has anyone seen anything like this or could give me any other troubleshooting steps I could try to follow? I've put the wireless charger and retainer and screws back in but haven't resealed the back glass in case I have to go back in.
Seems to me like the MMC (memory management controller) chip is dead.
That's a motherboard swap isn't it?
So I opened the phone as disconnected what I think was the screen and some other plug on the bottom left of the mobo maybe the touch synthosizer? I let it sit for about 15 20 mins charging. I plugged all the connectors back in and it booted properly.
Why did that work?
Now that it's up I did a factory reset put apps on one at a time and using Snapchat causes the phone to shut off.
