Dug out my trusty Z3TC 16GB WiFi to browse the web and its dead and refuses to charge on 4+ different chargers. Won't respond to power+vol up or show any activity.
Software was fine when I last checked, running CM12.1 and no issues.
Anyone see a similar issue and know if the battery is likely to have failed or something more fundamental?
I'm ordering a pogo pin charger to see if that works, had a couple in the past but the connecting wires in the stand broke.

Happened to me. Try this: NEVER LET IT GO FULLY DEAD

Yup, saw that thread. Looks like I'm out of luck as I certainly can't resolder any of the components.
did u try with a quick charger?
Peace to all
I've tried most chargers and I have a lot of them, including original chargers for Z3 and Z4. Even trickling on a slow charger should recharge after 24 hours but nothing.
Wish I'd remembered to keep it charged, can't even get a bootloader up.
Try this??
Press the volume up button and power button together for 10 seconds. This should cause your device to vibrate 3 times and then show the battery charging screen.
Nope, I've tried all of these already. Probably need to open it.
weird dude.as far I know,li-on batteries need to fully discharged once in 30 charges.I made it once (it closed from battery) but nothing weird happened to me.I am always on KK 4.4.4
or u can try press the tiny reset button near to usb port.here says that nothing is being erased.

Good news! Thanks to everyone here who convinced me to persevere and not sell this tablet as broken!
For 4 days I have been charging the tablet and trying power+vol button combinations a couple of times each day and finally, on day 4, I was able to first get a red led. After the led went out about 10 mins later I tried vol+power again and got the emergency battery graphic plus red led. Led went out after ten mins again and had to use vol+power. Seemed to go a bit strange at that point and charging halted. Swapped chargers and waited.
Next time was the trick, got red led, it went out and I was able to get the normal, smaller charging graphic. Let it get a couple of % for safety and hit power, resulting in a full boot. Tablet is booted at 4% and charging OK.
Thanks to everyone that helped out.
glad to hear!so can u tell us the working process so just us to know just in case?....

Exactly as per above, keep repeating the power & vol- sequence and putting on charger for a few hours. Exact brand of charger doesn't seems to matter, the one it worked on was a no-name two-socket UK plug charger from Amazon. Obviously a 2A+ charger will help. The cable used was a generic Samsung 1m (3ft) lead.
Just repeat the process and leave it on the charger in between. I'd recommend not charging a unit like this unattended in case the battery is damaged and there's a battery failure, I've seen a lipo fire and they're ugly.
Thanks dude!enjoy the best tablet! ?

Dude glad you got it working. I love mine but i have it rooted. hoping that the latest stamina battery return update is rootable

Hi everybody,
after several weeks of rest in my desk, yesterday I decided to use again the MW600 with my Xperia X10. I tried to turn it on, but nothing happened.
I realized that for sure battery was completely drained, so I put the device in charge for the entire night.
This morning, when I unplugged it from the DC charger, pressing the ON button nothing appeared on the screen! And furthermore I noted that, during charge, no animation of battery charging appeared on LCD: only a "static" icon of battery, as if it already was fully charged.
I have also tryed a reset by press&hold ON button, but no icon appears on the OLED screen!
Any idea?
Thanks in advance!!
Paolo
UP! Any idea? ^^
someone said holding the power button for a few seconds while plugging it in may help.
Hi,
thanks for your reply
Just tried, but nothing happened! :'(
mine got bricked too.. it happened after a work out. maybe it's not designed to handle continuous vibrations while running i guess. i took mine apart and was surprised to see a battery similar to the size of a AAA battery squeezed in there. it's 3-4x bigger than the one used in the DS980. i pulled the battery and put it back in and it still wouldn't turn on. anyway, i got suckered in to buying another one but this time it's white.. can't wait.
So bad to hear... it is possible that completely drained battery means permanent brick?!
well, when i plugged in mine after it was bricked, it would show the charging animation moving as if it was actually charging but the thing is it doesn't ever get the full charge symbol. then once i unplug it, it wouldn't turn on and shows no sign of life.
you have to replace the battery..
i read somewhere that those battery will die eventually so have them replace?
how long uve been using it?
about 6 months
My MW600's Display died las week. the Head set would connect to the phone normally but nothing displayed. I used it for 2 days and it was dofficult to control. So i contacted SE and they asked me to mail it to them. Havent returned my MW600 yet.
My MW600 also just died in this fashion a few days ago - the battery indicator says fully charged when plugged in, but it won't turn on once i disconnect from the charger - i use mine alot for work-outs (running) also -
did anyone find a solution to this?
If i need to get a new internal battery where do i get one of these from?
thx.
ps. - tried the "keep on charger;hold power power button ;disconnect while still holding power button method" but no luck

Hey, I'm from Argentina and I can't get this battery here. I found out in Amazon that there are at least two dealers, found one around $8 and another one like $15. I completely unmounted my headset and I'll try to get one of those amazon batteries but I will have a long time to wait now. I guess you can buy one and try to replace it. The unmounting proccess is really easy, you just have a screw under the power button (under a sticker) and you have to loose the clip (pushing sideways with the screwdriver tip. After that you have another screw and it's only that, just need to unmount the track controlling buttons.
Mine died during a motorcycle ride, I could revive it (it was weird because it had battery fully charged and it never happened to me) and then in a running marathon it just died after 15 minutes.. Since then it won't wake up. I read the battery lasts around 18-24 months only, I bought it in January 2012 and used it daily since then, so I guess the battery just died..
..............
Mine is doing the same thing. It's staying at only 2%. I'd try to set it to factory settings but way too risky with the battery that low. Let it charge overnight and everything. Going to play around with rebooting it a few times or charging it while it's totally off. The light on the power supply is green and working fine. The LED on the tablet is solid red.
EDIT: After many attempts and trying to reset it, trying to boot up while holding down the volume down button and plugging it and unplugging it from the charger while booting, nothing seems to work. It refuses to boot up at all. LED on tablet will flash red three times when I hit the reset button when it's unplugged. Light is solid red while plugged into charger and will flash three times red when I try to reset it while it's plugged in. Going to contact Sony tomorrow for warranty support if I can't get my problem solved here. Also I was not in possession of this tablet for the past few weeks, I had given it to a friend who was trying to sell it for me and he said the tablet wouldn't charge past 12% for a long time. So it looks like the problem has been getting worse over time and now the tablet seems to be pretty much dead. I had only used the thing for like 3 days too.
---------- Post added at 11:42 PM ---------- Previous post was at 10:54 PM ----------
After about 20 minutes with technical support chat just now they recommended to send it in for servicing. I'm going to call tomorrow for more information but I'd rather not send it in. I'm down in Chile right now trying to sell this thing. I had a friend bring it down for me and I don't really have room to bring it back just to get serviced and then have to sell a might-still-be-broken tablet back home in the USA. If anyone has any tips for getting this thing to get back to normal please help out!
Oh, the chat tech suggested unplugging the device and then holding down the power button for 30-45 seconds then plugging it back in for about 2 minutes and then try turning it on. It didn't work for me but give it a shot!
After letting it sit overnight I tried turning it on again and voila! It booted! At 2% battery still. Been trying to charge it for over an hour now and still not up to 3%. Situation seems pretty bleak. No suggestions from anyone? I'll be returning to the States in a week, I hope that someone has an idea of what to do by then.

It sounds like either the charger or the tablet's battery is defective. If you have access to a voltmeter, test the charger to see if it is outputting 10.5 VDC. As shown by the diagram on the bottom of the charger, the two center pins of the plug are used for charging the tablet, so connect a voltmeter to those two pins. The pin closest to the cable is the negative (or DC common) pin.
If the voltmeter indicates the charger is outputting approximately 10.5 VDC, then it is likely the charger is good and the tablet's battery is defective. If this is the case, the tablet will need to be sent to Sony for repair.
If the voltmeter indicates a voltage significantly lower than 10.5 VDC or no voltage at all, then the charger is defective. If this is the case, you will need to get a replacement charger, hopefully for free from Sony if the charger is still under warranty.
Having similar issue
I am having the same issue, sort of. I got my tablet the 08/08. As soon as I got it I updated to ICS, so I can't really say for sure if the update is to blame as I didn't use it much before the update. At first I got flickering on occasion on the screen. Like some random app, that I was not currently on, came to the front then disappeared again. Right now it is the 10th, at 1:32am and yesterday at around 4pm I had turned it off to go to the gym. I come back and it is not turning on. I set it on the dock and the green led turns on, and I manage to power it up. The screen though starts showing random messed up images like when you get bad reception on tv. I know the logo and power on clip it shows and I can see those colors but all warped. Then it disappeared and it showed the password screen fine and the screen was ok from then on. I lifted it off the port and it turned back off. I put it back on the dock and turned it again, showed the same weird images. When it was up fine, I went to battery settings and it showed the battery at 100% but where it says how much time I had left, it has 16secs. The dock and charger where fine since I got them. But I will check the volts.
I have an s-off rooted droid dna and i went to flash a new rom today(i have flashed a few before) and it failed twice so i pressed restart in TWRP and the phone shut off and nothing else....
i tried plugging it in to a power source, computer and even wireless charger but nothing.
i have also tried to hard restart it every way possible including pulling the battery quick and trying again.
was hoping someone on here might know something I am missing.
thanks.

Was the battery very low when you were doing this?
I had something similar (but different) happen the other night. I left the phone on a wireless charger and when I got up in the morning, the phone was completely dead. It's possible that I missed the charger and that the phone simply depleted its battery, there is no know I can tell.
I tried several different USB cables, wall chargers, wireless chargers, computers, and nothing would make it happy. Either nothing changed at all when I attached a power source or else the LED would blink on and off but it never gave me a solid charging light. I tried various charging techniques for 10 hours before I called Verizon for a replacement phone.
Later that night, I put it on a different brand of wireless charger and again it did nothing and finally put it back on my google charger at which point it started charging. It ended up charging just fine after that.
Although, it still wouldn't charge on some combination of cables, USB ports, etc. that used to work and that work with other devices.
I suspect that the charging circuitry is flaking out on the phone and somehow the different wireless charger made it reset some internal state or some other voodoo magic happened.
There isn't any great advice here other than to keep trying different power sources and see what is happening with the LED.

How long did you let it charge? I'd charge it overnight and try in the morning. If you got the phone from Verizon on contract, go and say the phone just died while charging and won't turn on now. I did that three times when I had a Lucid and I got 3 new ones free...

thanks for the reply and i did charge it last night from 10pm to 12 today and nothing. as for the verizon thing, i bought it off ebay with a cracked screen so i cant do that haha
how long was it disconnected ( i would leave it for about 5 minutes), and once you had it back on did you leave it on a ac charger(and not a qi one) for at least 12 hours? EDIT: just saw post above it didn't load for some reason lol. Dont hold volume down at first hold just power for for about 30-40 seconds the soft keys will flash then keep holding the device till you see white screen(if you get that) then let go and hold just volume down.

Just out of curiosity, what ROM / Kernel were you running when this happened?
Hi all,
My phone cut out at about 10% battery charge earlier and wouldn't turn back on. I thought it was probably just bad battery stats. But now I'm home, even after an hour on charge (and 30 mins on another charger) the phone won't turn on. It also shows up as an unrecognised device in device manager.
Whats weird is that when I first plug the charger in, rather than seeing the blue battery logo, I see an unfamiliar green battery logo as attached.
Has anyone got any ideas on how to fix this? (Tried booting with the volume up and volume down buttons held)
It's also come at quite a frustrating time, I may not be able to reply until Sunday night as I'm off camping in the sticks for the weekend.
Thanks

Sadly that didn't work.
The battery appears to now be taking a charge (300mA/h according to a USB multimeter), but I haven't been able to even get SP flash tools to recognise the handset sadly.

That is the conclusion I'm coming to, sadly there doesn't seem to be a UK stockist of the battery yet, but I guess in the mean time I can see if the seller will honour any form of warranty on the product. For now, I'm back on my old G3 and it doesn't even begin to compare. I loved my Elephone.
Bad luck my friend.....I have a samsung galaxy 2 and one day run out of battery and never awake again....weird things
I think it should be cover with warranty.....Is one year in China
Type a email to Elephone support and they must be assist you because the phone is less than one year in the marketing.
I hope you will have a possitive news from Elephone
Thanks, I'll let you know how I get on.
I have the same problem a while ago with the green thing logo while charging , I even try it on wireless charger but it has the same thing with the green logo of battery ...but luckily it charge normally with blue logo
I have seen this on my screen a few times when I ****ed my bootloader during flashing. Device ended up being semi-bricked. I could not flash via SPtools because my device didn't get recognized. I was able to fix it luckily!
Hi all, sorry for the delay in responding.
So, the first problem was the battery. You need to charge it beyond 3.8v I think to get the phone to turn on, probably better to get it to 4v so you have enough charge stored to use the phone. The phone can't charge the battery below a certain threshold (around 3.7v) so you have to remove the battery and use a lithium-ion battery charger (any phone battery charger), these are available for about £2 on ebay.
In my phone the USB port had also stopped working for data transfer. I tried changing the board with the USB port on to no avail.
I replaced everything but the screen in the end to get it working.
Are/were you on stock OS or had you replaced it with another rom? Just for a bit more clarity of the problem.
I've had the S23 Ultra (US, unlocked, from samsung.com) for a couple of months. I didn't root it, drop it, or splash it with water. I charged it last night, but when I woke up this morning, there was no sign of life: a black screen, no sound, no reaction to charging (even after long charging with a different charger and the cable), no reaction to a long press of Power + Vol Up/Down, and nothing detected in adb.
So I have a few questions:
Has anyone else had a similar experience with their device?
Any suggestions on how I could resurrect it?
Do you have any ideas about what might happen? Throughout the two months, I used the same old low-current (850 mA) Motorolla charger. The charger is still operational.
My current plan is to contact Samsung Support.
Any advice is appreciated! Thank you!
Have you tried using a higher capacity charger, like an official Samsung charger plugged into the wall? Have you tried a wireless charging pad to rule out an issue with the USB-C port? Samsung still uses the lowest grades soldier pennies can buy on their most premium devices.

Looks like you've tried everything basic and the phone's just dead. Could be a motherboard failure. Best to go to Samsung instead of breaking your head, as it's still under warranty. At least that's what I'd do in your position.
Wish you the best.
Try half an hour charging on wireless charger if you haven't tried yet
Saw this happen on a Note 4 back in the day. It wasn't really dead but in a weird power state. Fully charging for a few hours (even though it showed nothing) then holding power and volume up and down got it to reboot.

My old Note 4 went into this state and didnt manage to revive it with Power and Volume Up + Volume Down combo. The only sign that tells me it's not fully dead is the green notification light when I do the above combo.
About weird power states - I had Galaxy Buds Pro, which refused to take any charge - wired charging did not work and wireless either. Only way to revive it was to use wireless power sharing from the phone. Problem did not reappear later. Go figure...
Really? I "didn't root it" as if that is a bad thing
You obviously charged it with faulty charger. I experienced the exact same thing. I was about to cry but then i remembered i was testing a cheap, fake Samsung charger...
Then i plugged the phone into REAL charger, waited for 2-3 minutes, phone was alive with all its glory.

Had this happen on my old s21u. Contacted support and told them I had done all the steps you did. They had me send it in for repair (was actually 2 months after warranty expired but they still agreed to repair it free of charge) and ended up changing the main board, usbc port and something else. Never happened again after (didn't change chargers or anything). So yeah, contact support that's your best bet.

It will be hard to do it if he can't even turn on the device i any way... No combination of buttons work, no way to turn it on with charger or ADB...
As its apparently either dead or in power-off state you could try to start it into download-mode by:
1. pressing Vol-Up and Vol-Down together and keep them pressed
2. plugging in a USB-cable connected to either a powered-on computer or a charger while keeping the buttons pressed
Normally it should boot into download mode (you can release the buttons after boot-up ).... Maybe this helps if the power button is broken....

Can't a power surge damage a device? It can happen either during a storm or by using a non-recommended charger. It can fry certain components, even though phones have protection.

No, it was like... My fake charger suddenly stopped working and my other phone recognized the charger + cable as a DATA TRANSFER DEVICE. It is really hard to describe the experience. No charging, my fake charger was recognized as something else..
The experience was... My S23 Ultra blacked out. I thought it was charging. Then, complete darkness. Didn't respond to power button.. Nothing. I thought it was bricked. Then i got up and found my other charger. Waited.. 10 - 15 seconds later my phone was back again. God i swear, i was shaking with sweat. It has been almost 1 month, my phone is just fine..
That day i decided to go with only geniue products. Maybe my phone protected itself by bricking itself. I really dont know.
To me it sounds like what you experienced was just an empty battery .... without juice in the battery the phone cannot do anything and the defective charger did not charge the phone while you thought it did....
Update from me: I scheduled an appointment from the Samsung site with an authorized service center (Best Buy). They checked my phone and said that they couldn't fix it if it wasn't turning on, and I had to send it to Samsung. That was unexpected.
I sent the phone to Samsung, and today I got a message that they could not reproduce the problem. I wasn't able to communicate with the service worker yet. My concern is that it could be a bad internal cable connection that restored the circuit due to the shipment vibrations. If so, and they will not check it, I could end up with a phone with a faulty connector that could die at any moment (hopefully during the warranty period).
It's also possible that being in the weird power state was fixed by simply letting the phone completely deplete of charge so that it properly turned off, recharging, then rebooting.
I had this problem on my old s7 edge. It seems that samsung never fixed this problem. The screen would stay completely black, unable to do anything until the battery completely drained. The device itself was never rooted or modified. Pretty disappointing it was never fixed.
