Dear friends,
I have solved the problem myself but I want to share the problem I faced to you, so as to contribute a bit of knowledge.
Precondition: I always use a magnetic stand to charge up my z2.
What happened: Last night I was in my grandma's house and I forget to bring my magnetic stand so I used the standard usb charging. That night, a power outage occur. Total blackout. I didn't notice because I was sleeping.
The next day when I unplug the phone, I noticed two things: the battery was at 47%, almost the same as the previous night, which is understandable given the blackout occurred. Secondly, all hardware buttons (the power button, the volume adjuster, and the camera button, as well as the magnetic pins) all fail to work. I was only able to open my phone because I enabled the double-tap-to-awake thing. The usb port also didn;t work, i cannot connect to a pc, and neither can i charge up.
Solution, I pulled out and re-inserted the micro-SIM card while awake, this automatically rebooted the phone. After that, it all worked.
Thanks for reading.

Too bad that last thursday I used the charger from a kit similar to this (link found in the forum 3 months ago).
(h**p://w*w.befr.ebay.be/itm/Dock-Sync-Cradle-USB-Charger-For-Samsung-I9100-Galaxy-S2-II-Plug-/260876977248?pt=PDA_Accessories&hash=item3cbd7ac460), directly (without the cradle)
It was the first time I use the power adapter directly to recharge my phone.
And since thursday my phone detects unexpectedly usb connection (and says I ave to close all aplications to use with Kies etc...).
I suppose it is no coincidence and that this fu***** charger damaged a capacitor or another electronic component of this kind inside my phone!?
What do you think ?
What can I do? Send it using warranty? Disable USB detection (how?)?
Thanks a lot in advance for your help!
Edit: Now the phone is not recognized when I connect it to computer (usb) or it starts the car mode!!!
A lot of people have this. Try brushing the usb connector on the bottom of your phone using a CLEAN and DRY toothbrush.
I had this problem, this fixed it for me ever since. Also bending the connector a TINY bit to the middle of the hole may help. But watch out, as it's horribly thin.
Two connectors are bent because of your new charger, or dust is causing the problem.
Thanks for this first answer! But...
Three others things (I've cleaned the connector as you said to):
The screen lights up by itself, too! And 9 times out of 5 when I press the power button (in order to lock and switch off screen) the phone just freeze and the only way to get it back again is to remove/replace battery!
By the way the battery drains faster than usual!
Do you still think it's only a matter of dust/connector (just asking but strange coincidence...)!?
Hello I have exactly the same problem since 2 days first it started thinking its connected to the USB, second thing is it wakes up soon after you have put it down and if you press the power button it freezes I have tried it more than 50 times and it freezes every time (when its connected to the charger only froze once) and today when i try to connect it to the USB nothing happens.I have tried Hard Reset , restore to a stable setup with CWM but it wont help. This happened when I got home after I was 2 hours outside working and it was very cold and moist but I only had the phone outside my pocket for 1 - 2 minutes to make a call and some very tiny drops got on the screen.I regret taking it with me if I only knew that was going to happen. One other thing I had an App to track the battery state and now when the phone thinks its connected yo USB but its not the program says my battery is over voltaged. What happened with your phone . Can someone help
Hi guys,
I've had me evo3d from the first day it came out here, august 6th. Never had any problems at all. Until now. Srry about the novel... I've highlighted the most important parts for your convenience.
About 2 weeks ago, i dropped my phone from about 60cm, but with no apparent damage. Later that night, my battery went completely empty (not unexpected, it was a long day). Plugged it into the charger when i got home, led flashed to indicate a completely empty battery then stayed on to indicate charging, no problem. Then it stopped charging after a little while and didn't resume.
I took the phone apart so see if maybe some wire had come loose from falling. None had, but after putting it together again, it did charge again for a moment (also showed flashing leds again), and then it stopped again.
A friend of mine suggested it might be that battery's contacts, so he scratched them with a screwdriver. This actually seemed to help and everything was fine for about a week and a half.
Now trouble has started again. Taking the battery out and blowing on the contacts (NES cartridge style) worked at first, giving me about 10 minutes until it died again. But it seems to be getting worse, and by now it will only turn on or even just charge sporadically. Always flashing the led, indicating the battery is completely empty.
additional info:
It's not the rom that's faulty, as i hoped at first (re-installed an old rom after trying some ICS-goodness the day before all this started), because it also crashed in Recovery at least once. And i've already installed a diffrent rom without any success.
When it crashes, it doesn't just die instantly. Instead, it freezes for about 1/3 of a second. When it crashed in Recovery, during this freeze the text got a weird yellowish background-color and a different font color as well.. but the parts of the screen without text retained their original looks.
What else could i try to fix this? I don't know anyone with a shooter, but i've heard pyramids battery works as well, is this true? Can i try one of those to see if it's just the battery that's tripping?
Let me know if you need any more info.
Thanks a lot for your help in advance!
I didnt had the same problem, but I had something similiar.
Try this:
1. Unplug from charger
2. Get battery out
3. Wait a bit, and put battery in
4. Press Volume Down + Power button
or
4. (better solution) Press Power + Volume Up + Volume Down + Camera button
5. Phone will start
6. Just plug it in
It's known as "Chargning bug" when you flash some roms
It's the charging bug due to flashing clockwork recovery-- search the forum there are many similar threads and solutions
Hi,
Thanks for your responses. But that's not what's happening. In fact, i have an old clockworkmod that's never been a problem at all and i never updated it.
I tried your solution, though, but it only allowed my phone about 15 minutes of charging before it died again.
If it charges, it charges just fine while the phone is off.
Hello,
I have an unrooted Z2. With around 30% battery left, I put it in the charging dock on my desktop yesterday evening. After 1 or 2 hours, I noticed that the phone is completely dead - no LEDs are blinking, no vibration, nothing. I tried pressing the power button alone, in combination with VolumeDown, VolumeUp, CameraButton, for more than 30 seconds each. I tried pressing down the tiny red button next to the SIM slot for awhile. Nothing. Phone is dead like a brick.
The only result I'm getting is when I plug it into my computer (ubuntu 14.10) - the LED bar on top is showing a constant red color in this case. Doing the button presses outlined above in this situation is also pointless.
I'm installing flashtool for Linux right now, the connection is pretty slow and it will take awhile. I hope to find out more afterwards. I'm a newbie when it comes to flashing sony phones, only found out now about flashtool. Any advice/tip on how to proceed, or if it even makes sense to dig into this, is highly appreciated.
Thanks in advance!
Hello,
are you perfectly sure your dock was connected properly and it hasn't discharged your phone? Maybe there was something wrong with it.
I had similar situation while I was low on battery and I was creating backup in recovery. Then I fell asleep and I have found my phone completely 'dead'. I connected it to the wall charger and nothing. No led, no nothing. I have even connected it to my pc and also nothing happened. Then I connected my Z2 to the wall charger and I left it like that. And after few hours, out of the blue, just turned itself on, just like my old Nokia n95.
I'm sorry it's not quite solution you looked for, but give it a try. Essential is to charge it via wall charger.
Good luck!
Do what @amon87 says OP. Charge it on a wall charger for a minimum of 3-4 hours; If that doesn't work, can you specify whether you were using a legitimate Sony dock or a third party dock? If it was third party, it could possibly have caused a hardware problem with your device via the magnetic charge pins (not extremely likely but not unheard of). Worst case scenario, send it back to Sony in the next few days. The warranty will cover it if you haven't caused water damage or anything like that.
Thanks for your replies! I also hoped for a sudden discharge, so I removed the device from the dock, plugged the USB in directly, and left it overnight - still nothing. Also, I have the original Sony dock, and have never exposed the device to any water.
Found out the model number in the meantime, it's D5303, if it's of any help. Flashtool does not see the device, unfortunately. I just found out that Sony describes an option to restore your device through the official PC companion app - I'll give that a try when I'm home, and will report back tomorrow.
Otherwise I guess my only option is the warranty.
There's also an option to quickly plug in and out charging wire to kick-start the battery. Unfortunatelly i have no further ideas to help you out.
Don't give your hopes up, try again. There's been a thread of a guy whose Z2 turned itself off and it seemed dead, but after a day or two it just turned on.
So, of course it's also not detected by Sony's "Bridge for Mac" app. Plugging it in and out brought also no results.
As the device is still covered by warranty, and I have yet not tampered with it, I've sent it in for repair! My pocket feels so empty now, i wonder how life is going to be without a phone. Apparently they need 5 - 10 working days.
Thanks for your kind support, guys!
Sorry to hear that. Hope it will get fixed!
Hi folks
Have an issue i think its straightforward battery replacement and ordered one off amazon already but will take time to get to me
Just wondering if anyone has same issue or can clarify /verify my suspicion

Thanx in advance
I had a similar problem. When the phone turned off itself after discharge the battery, I can't turn it on. Even after plugged charger some minutes does not LED indicator light. And after several minutes with charger, phone is ON. My old battery is bad, with my new battery all the same.

I’m having the same issue, I’ve tried a new battery and all that happens is that the phone gets warm and the phone is complete dead. I don’t know what’s wrong with it.
I have two dead ones too here. one died in februar, the other yesterday.
No Solution found yet. Led is not working, phone gets warm while charging.
I really want to access the data on the Mainboard, i hope that someone will find a solution.
On youtube comments i have read from several others who experienced the same..
Same problem here
My phone had an argument with the toilet.
I dried it out and it booted up just fine.
Then left it charging. It got hot then froze. I striped it all down and dried it out again, but it now appears dead.
My wife has a G5 so I'm able to fully charge batteries in hers and try them in my phone, but to no avail.
If I put the battery in and press the power button, it vibrates, but no sound, no screen, not USB recognised.
I've tried everything to recover it including but not limited to:
stock charger
multiple different USB cables
plug in to PC
plug into PC while pressing volume up/down and various other combinations
4 different bottom modules (2 standard, 2 cam plus)
stripped it down completely and cleaned all the connectors with isoproply alcohol
Seems to be dead as a dodo.
I have pictures and videos of my son on there that I'd love to recover.
Has anybody successfully recovered data off of the internall MMC from a dead motherboard?
Thanks!

You can get data from your Google backup. If you had backups turned on go out to Google from a laptop and download the last backup before it died. It should have all your pics etc
I recently picked up this galaxy s6 edge from a friend that upgraded to a new phone. It won't turn on, neither to android recovery, nor to download mode nor the android. I charged it via wireless charging overnight and i tried for around an hour with a usb cable. What do i do?
same issue i am facing, i tried original charger, wireless charger and fast chargers from many different brands. but all failed. The device only gets warm/hot while charging and nothing happens. neither download mode nor recovery mode works. I am kind pf stuck without any solution, my device was used very rarely and its like an brand new device. Doesn't know what to do, if you find any solution then please let me know too. thanks in advance
Same problem. If I press power button very long, blue light comes on. Then it's stuck and stays like this until battery is flat. Battery charging is not possible: device heats up (tried USB and Qi), but battery doesn't take any charge.
So I opened the S6 and checked the battery directly. I can charge it directly with a lab power supply and when I plug it in and press power button, the blue notification light comes on again until battery is empty again. I can also see that only ICs get hot, but not the battery when plugging in USB.
So, it's definitely some hardware fault. I suspect power IC that is not able to power up the screen. But I don't know. I will investigate further but it looks difficult. However, I have seen many YouTube videos with same symptoms, but problem was always different than mine :/
Hi guys,
This thread is 2 months old, any of you managed to fix the problem?
I am having very similar problem. My phone was on a shelf for about a year and a half. Before now it was working perfectly. Now I can't charge it via USB or power adapter. When trying to power it up or get into download or recovery mode, nothing happens. Computer does not see it. Tried different cables, USB ports, power adapters..nothing.
The only thing that is happening to the phone is the battery logo appears when trying to charge it, though the green bar does not go over battery, only the empty grey battery with lightning icon in the middle. Also the screen does not go dark after a few seconds as it should and the red/blue LED does not turn on.
Is this the signal from the phone, that the battery is to deeply dischareged and cannot be charged again? I am googling all over the web and can't find anybody talking about what phone does in case of to low voltage on battery.
PS back does not seem to be bloated, USB port was working perfectly last time used
Please try to help, you are my last stop before opening the phone and start probing the poop out of motherboard to see what gave.
EDIT: something interesting happened just about an hour after my post. The battery suddenly started showing % of charge and the green bar started running, computer recognized the phone.. as everything should be.
My FIX: leave the phone pluged in and charging for about 3days and it will start working again.
My semi professional explenation of fix and problem: the phone has a ''backup or reserve'' battery. It is actually main battery but the last I think I read somewhere it is 20% of capacity, is reserved for phone exclusively for the clock and all other electronics that need power when switched off. Now these 20% probably were discharged due to laying around for almost 2 years.
It took me 3 days of charging to fill up these ''20%'' I guess. Probably because Lithium batteries are charged VERY slow at very start and end. This is safty procedure for ALL Li batteries.
If any expert can confirm my conclusion please do so, to help other people.
To answer partialy to my question: The phone tells you battery is ''deep'' discharged when you only see the charge icon without the green bar.
In the mean time I was writing this edit I came up to 4% battery and turned it on!
