Zenfone 2 not charging or booting - ZenFone 2 Q&A, Help & Troubleshooting

So, the other day I accidentally dropped my Zenfone. When I picked it up, it had been shut down. I couldn't boot it up anymore after the drop. After like maybe 1 hour I opened the phone up and reattached the battery wire. Then I got it working. But then the problem was that the phone got really hot, even when I wasn't using it.
I waited until the battery was completely dead and then tried to recharge. And now the problem is that the phone won't charge at all. It still gets really hot. When I plug the charging cable in, it just vibrates, shows that it is charging, but then just after 20seconds it stops.
And now I'm asking, what should I do? I also tried to disassemble everything and then assemble everything back again, but with no luck.

Battery not charging after bike trip - is it dead?

Hi!
A few days ago, I was on a three-day biking trip where my Galaxy Nexus was in a back pocket, trapped between a sweaty back and a very heavy backpack.
I had it turned off for most of the trip, and never charged it once on the trip.
When I got back, I tried to turn the phone back on, but nothing happened. I thought that it must be the battery sucked out, so I tried charging it, but no response (it didn't even show the charging symbol). Then I kept it plugged in for an hour or two, and it charged again! I thought everything was all right, but it wasn't.
My problem is that it doesn't charge when the phone is turned on, and only partially charges when it's off. When I plug in the charger and it's off, it shows the lightning icon, then the charging animation for a few seconds, but then it's starting again at the lightning icon, then a few seconds animation, repetitively for ever.
I think something's wrong with the phone's micro-USB power plug, as I've tried two batteries (one of them I didn't bring on the trip) and it does the same thing with both.
Is there any way I can try to fix it myself, or will I have to send it in for reparation (and will that work), or do I have to look for a new phone?
Thank you!
Have you tried charging with a different cable directly from USB on computer, or from a car charger (to eliminate your wall charger and cable)? I'd try that before assuming there is a problem with the phone itself.
Did you find any solution for the problem ?
Hi,
Were you able to find the solution for the problem ? I am kind of facing the same problem :crying::crying::crying: . The lightning screen shows up and then charging screen shows up for 2 cycles and then it goes back to lightning screen .
Regards,
Tas
Water damage comes to mind when you said sweaty back.

A bit late, but I always put my phone in a zip lock bag while biking. Thought if it after seeing condensation on the screen after a few hours on the bike. You can still interact with the touch screen without removing. Best of luck getting things up and running.

Galaxy S II Won't Turn On or Charge!!!

BACKGROUND:
At first, it just started turning off for no reason (probably a month and a half ago).
Then this week, it would start to randomly turn off, and start vibrating constantly when charging. After fiddling with the buttons, it would eventually find itself into download mode and then later turn itself on.
NOW:
Monday morning, after several days of draining the battery to 0% (due to me solely charging it for an hour a day), the phone went dead. Then, that night, upon trying to charge it and turn it on, it remained stuck on a black screen. After taking out the battery, it would continuously beep while still connected to the charger. As soon as I put in the battery, it would become COMPLETELY unresponsive, with and without the charger. After fiddling with it for over an hour, I put it down and slept, leaving the battery and charge in the phone.
Tuesday morning, I clicked the power button, and the phone flashed to the lock screen. It displayed it was at 0% battery, but I think it showed a charging sign. I used the phone for almost 2 minutes, checking my texts, before it again went completely black. The phone became completely unresponsive (no beeping or anything, regardless of anything I did). I connected it to a wall charger again, and left it there for the entire afternoon.
Then when I picked it up at around 6 o clock, I discovered that the continuous beeping stopped, and it would only beep after holding the power button for around 5 seconds. It could beep regardless of whether the battery was out or not.
After charging it all that night, I found I could make it flash the Samsung logo for a fraction of a second after holding down both volume buttons and the power button. I looked it up, and supposedly it brings you to recovery mode, but I believe my phone is switching off immediately after bringing up the logo.
At around 12, Tuesday night, I again decided to hold down the power button (just to reassure myself of it still somewhat functioning), and it powered on for around ten seconds (!!!) . It got all the way to the end of the pink loading bar screen, but then beeped and restarted. The second time, it lasted only around three seconds, without even getting to the loading bar screen, before powering off. It became completely unresponsive afterwards, no beeping, regardless of where it was charging and whether the battery was in or not.
Wednesday morning (today), after having left it charge all night, the phone still was completely unresponsive. I then left it to charge the entire afternoon (until now), and it was still completely unresponsive. I took it apart and played around with the power button, but it didn't seem to be stuck. I've now put it back together and leaving it connected to the wall charger once again.
What I've Tried:
Tried connecting it to Kies (computer doesn't even recognize it)
Tried putting into Recovery Mode (unresponsive)
Tried putting into Download Mode (unresponsive)
Switched chargers (unresponsive)
Held power button (beeps, now doesn't do anything)
Held both volume buttons and power button (beeps then quickly flashes samsung logo)
Cleaned off some of the micro usb lint with a tooth pick (coincided with the stopping of continuous beeping, not sure if it caused it)
What I think it could be:
Faulty power button (this is what I thought it was, but now it's not vibrating)
Faulty battery (I kept draining to 0%, but if this is the problem, it doesn't explain the phone not displaying anything when it's connected to a charger w/o battery inside)
Faulty usb charging port (I've heard it sometimes causes vibration problems. wouldnt explain the restarting).
Fried motherboard (phone has had some water damage, but I'm not sure if it's the MOBO, considering its symptoms)
HELP WOULD BE GREATLY APPRECIATED.
Not Alone
hey, this isnt really an answer, but maybe something to bump this up. Mine went last night.... won't boot, won't charge... goes into download mode but no matter how many times i switch cables, install Samsung drivers, install Keis, or anything imaginable- i cannot get it to communicate with my PC. if i could i would be able to fix this problem.
i really hope that someone will take a look at these issues and give some input. my call to Samsung was useless, i wasted hours with redundancy. I bought the phone used off Ebay in mint condition... have taken it apart and cleaned it with no avail. i fear that soon the battery will be dead and there's no way to charge it. sucks. Samsung really should recall/replace this because so many people have similar issues. whether it's the USB Flex or the battery or the motherboard they should be responsible. looks like ill be getting a nexus 4 afterall.
please let me know if you figure anything out.

It may be your battery, u need to remember why they tell u not to run the phone that way, the batteries our phones run need to maintain a certain charge in order to work correctly, if like u said u only charged it an hr or so a fah for over a week and drained completely more than once u may have rendered ur battery unable to hold a charge, in effect not allowing the phone to run its boot process, I would try a new battery, because beyond that the only other logical explanation is a hardware failure, stuck power button wouldn't render the device unresponsive only when the battery was put in like that, it would bootloop, have u ever just held ur power button in? The phone vib an shuts down a. Vib again n shut down, not become unresponsive, I would try a new battery, and if it works, respect the charge lol

I would agree, seems to be the battery. I bought 2 batteries and a 110V charger on eBay for $30. They don't have the NFC antenna in them but I've never missed it. Not only that but charging that way saves the wear and tear on the USB port.

[Q] D855 not starting and not charging suddenly

This phone was stoped work suddenly during a call. Not droped, not water damage. Does not respond to pressing power, pow+vol - and pluging charger.

broken motherboard, bring it in for repairs
Mine has done the same tonight... I was using it, put it down for 20 minutes and then picked it back up. No power, no charging and unfortunately nothing in the other thread helped. Sigh, I only just got back from a holiday and really can't lose the photos on it.

Not Bootloop of Death... but something altogether different....

Good morning all,
I bought a used 5x on eBay which was sole as spares because it had a red charging light, wouldn't turn on and when it did it froze.
Sounds like the dreaded bootloop of death. Awesome, easy fix. £18 and it was mine.
I got the phone and stuck it on to charge, low and behold, red light. Ok, removed the motherboard, in to the oven for a bit.... stick it back in and it powers up enough for me to boot it and allow oem unlock. Brilliant.
But then, it stayed on... for hours, 14 in fact, working perfectly. Then as soon as I plugged the charger in it just stopped working, it became unresponsive, not even a hard reset did anything, no red light, nothing.....
So I repeated the motherboard in the oven and woop woop, it fired up again, no issue.
This time I flashed the latest Oreo build, and the 4 core boot.img on the BLOD thread and it stayed on again, for almost 24 hours. Then it needed a charge so I plugged the charger in and it just froze again....
I'm wondering if there is an issue with the battery, or with the charging port, any thoughts? Or questions?
Thanks guys
did you mean pull yhe plastic body on back, remove the screws ,pullthe joints of camera,speaker and other..then pull another hardware surface..and then i find the whole motherboard and just put it into oven??
Qualcomm's Power IC is dead

Unresponsive but can it be salvaged?

I was browsing the web on my G4 (US991) the other day when the it froze and restarted. I set it down while it was rebooting and came back 5-10 min later to find that the boot screen was still up. After another few minutes absence I returned to find it entirely unresponsive. It does not respond to any attempt to start or reset, no LEDs turn on and nothing appears on the screen when plugged in, and my PC does not recognize any device when it's attached. The only sign that electrons are still moving in it is that the battery will warm slightly when plugged into the charger for an hour or two (this did hot happen at first, perhaps because it was nearly fully charged when it died?).
While I wasn't present to confirm it, it sounds like the phone may have gotten caught in the infamous bootloop. However, its complete unresponsiveness seems to be worse than most cases. I haven't had any battery issues - it holds its charge decently, isn't bloated, and still shows 4V on my basic multimeter.
Should I buy a new battery, bake the board in the oven, or light a candle and christen it a paperweight?
