[Q] Sony Xperia Z1 - Completely dead (no led/no nothing) - Xperia Z1 Q&A, Help & Troubleshooting

Hello.
Please take your time to read this message.. It contains detailed information about this case...
I have a broken Z1 phone which I'm trying to fix. It all started with the phone turning off randomly, and wasn't possible to turn it back on. Not using the power button/red reset button or using power + volume up together (this worked previous times).
When the screen died, I could see white blocks of pixels moving around a few seconds before it completely shut down. There were no signs of life after that, the LED was completely dead as well. The computer didn't notice the device if I connected it with a USB cable. If I tried to charge the phone, the LED wouldn't turn red.
I decided to wait for a week in order to see if the battery could run out of charge. So after a week I took the USB cable and started to charge it. The LED turned back on, with a red color, which is correct when it is charging.
I thought it would work to boot - but nope, it did not work at all. Now is the time I decided to open up my device. I used a heat gun to heat the back edges of the phone. I then used some palastic tool to open the back cover from the phone. It all went very smooth and I disconnected the battery from the phone (removed the cable from the motherboard).
I let it be for about 10 minutes. After that I inserted the cable back to the motherboard, and tried to boot. This time, nothing happend again.. So I started to charge it, and a screen came up saying 1% battery... So I let it charge the battery for a few hours until it rached 100%.
The battery is now 100% charged. The phone still refuses to boot up the first time. The second time I tried, it worked. I was able to connect my phone to my computer, so I took a backup of all files. I downloaded Sony PC Companion, and made a factory reset. This went very smooth as well.
I thought everything was fixed after this - but nope. The phone randomly shuts down a few times, and each and every time, I'm just starting it again (it did crash both when I was using it, and when I did not). I was speaking on the phone with it yesterday for 1 hour (used a bluetooth device), without the back cover connected to the phone. The call went very good and the phone didn't crash anymore that evening.
I thought everything was good, once again. So I was letting my phone be powered on during the night when I was sleeping. When I woke up, I went to check the phone - and it was: dead.
Since this, I have not been able to power it on again. No matter what I do. I have tried to disconnect the battery, check for cables that aren't fixed and so on.. But everything seems to be OK.
My thought was that the battery was bad, so I went to a store in order to check if the battery is OK or not. They tested the battery with some kind of device, and said it has about 40% charge left.. And they didn't see any issues with it.
So... now I'm wondering, what kind of parts do I need in order to fix my phone? Is it just a new battery, or is it the whole motherboard that is gone? What do you think? I know you guys are very experienced, so I have high hopes of help from you.
Regards

Hello!
Sorry to hear about what happened to your Z1, I'm currently in the state that my phone has a red LED when connected to anything and stays like that, PC doesn't even recognize it.
I see your problem is different, I'd suggest you to start here and hope for the best. Unfortunately I can't do that to my phone because PC is not recognizing my device.
Good luck
Regards,
~J2C

Thanks for your reply. I have already tried that, however, my PC is not recognizing the phone either - so I'm not really sure how to proceed.

Well, thank you...
I decided to take apart the device even more, and I found something on my motherboard, which probably is rust.

Hello.
Have you tried Volume up + power button pressed together for about 10-15 seconds? Do you feel any vibrations, how many?

Download Sony PC Companion, plug in your phone and follow the instructions in order to reset your phone. If that doesn't work, then you have probably had water or some other hardware failure.

Is this problem will cost me a lot of money if I'll bring it back to Sony for them to repair?

Not if you repair via Sony PC Companion. It will re-install the system on the phone, so in case it is a software error, it will be fixed.
However, if that doesn't help, then you need to check if you have any warranty valid on your phone. Even if you have warranty, it is not sure that Sony will cover costs for repairing your device. For example water damages will most likely be refused, and you'll have to pay for it yourself. I don't know how much it would cost though.

How to unbrick a "dead" Milestone.

After an unfortunate rooting session with my Motorola Milestone, the phone now returns into an "dead" mode. It refuses to start at all. I tried charging it and see if it starts by itself, but it doesn't budge and the little while led doesn't lit. The only time when it lit is when I connect it to the PC. I tried putting in it a new battery, taking out the SD card and SIM, but to no avail. I remember seeing a video where a guy used a dissected USB cable to spark the phone into turning on again, so I take it I'll have to use a "hardware approach"? Please help.
I tried following this guide, though without success. The phone still has that white LED lit when it's connected to the PC.
After a reply on this thread I also made, it might be possible that the battery is charged, but the phone refuses to boot at all. Is there any way to unbrick the phone in this state?
Do you think your device is really BRICKED?
If so, you can try to flash your original sbf file into your phone. Guide here: http://forum.xda-developers.com/showthread.php?t=696845
If you are using a Linux, google for "sbf_flash".
I agree with my front floor..ermm, u dont need to worry about its 'dead'. just flash original sbf can rescure your phone.
I had the same problem too, but good news is I tried to revive my phone successfully recently, btw your phone is not 'dead', it's just staying in limbo state, the solution is to pull out the battery and don't connect to any usb, don't try to power it up, it must be completely out of power wait about 12 hours, and then try to power your phone, I think there is some capacitors in the phone which retain the phone state, to make it out of power will wipe out it's state, good luck

"My phone is in limbo state... "
That's a pretty cool statement.
From technical view, it might have happened that something caused a kind of deadloop when reading scratchpad SRAM inside OMAP processor.
This SRAM, as well as the internal RTC is powered by a small battery soldered on the mainboard, while the phone is shut down and the battery is taken out.
What you did was, to wait untill this battery became uncharged.
All SRAM and RTC setting as well then gets erased.
Afterwards the CPU will start up with empty scratch SRAM, might be called a "real" cold boot
Normally the phone should not behave like this. Even if SRAM is not valid the phone should boot up...
...but anyway as you observed it like this, it might happen.
@andoruB:
Apart from that, the Milestone is hard to brick in general.
Might happen though, if you do evil things while flashing new firmware.
Especially while flashing bootloaders...
If you got some more information about the things you did, would be helpful!
Good luck anyway!

how did u root it? can u give a more detailed description? and hows ur phone? sometimes, the milestone would just shut off and wont come up if the battery is gone. Try charging it for maybe 2-3 hours, untouched, and see what happens.
Have this exact problem. Was doing a nandroid recover when the phone got stuck. Pulled the battery out. Placed it back in, pressed the power button. Nothing.
Led lights up only when connected to the computer's USB. Battery was charged before Nandroid recover. Used nandroid a lot of times but for some reason, my stone stopped playing nice.
I just removed the battery. Hoping this works. Can someone please post if you got this same issue resolved? I like this phone no matter how slow it goes sometimes. Thanks!
I completely forgot about this thread, sorry guys!
I don't remember exactly what happened, it's been so long... but I do remember I left the phone "inactive" (it's not like i had much of a choice! XD ) for 1 or 2 months, with the battery out. After I got hold of a wall charger, I plugged in the battery, after I plugged in the charger, and what do you know? It worked! It started charging (was 60% charged, fully charged, I unplugged it, but after putting it to charge again just to make sure it was fully loaded before I would flash a new ROM, it was charged up to about 80%, weirdly, so I guess it was a weird battery problem)
I do remember I didn't do anything to it, so I'm not sure what to tell you guys to do, except leave out the battery for a month or so ^^;

Xperia T won't charge when switched off

I have Xperia T on official 7.0.A.3.195 firmware.
It is not rooted and boot loader is locked.
Problem is the phone won't charge when it is switched off and I guess that is not good because none of my previous Sony/Ericsson phones behaved like that.
I have read somewhere that this behavior is specific for some versions of CWM, but obviously that is not the issue with my phone.
Also I have found that problem could be related with chargemod file in phone/system/bin, which should be changed, so if someone can send me that file I can try to solve it that way.
Anyone else with xperia T experiencing this issue?
Any other idea how it can be solved (I have already tried factory reset)?
Thanks.

If you have not tampered with the phone I would be unhappy with it and take it back to the shop for a replacement.
Or you could repair in pccompanion.
Mine wouldn't charge properly when it was on and I just got it tonight and then when it was off charging was on and off like it was getting unplugged and plugged in again I pressed the power button and now I think it's charging but it didn't turn on I hadn't brotherd to press the power button again just yet

Charging on and off loop happened to me as well at first, then I unplugged and plugged the charger again, but nothing was happening.
After I switched the phone on it started to charge. Now it charges normally when phone is on, but still noting when phone is switched off.
I have also tried firmware repair in PCC and it didn't help, so I think I will return it to the shop and ask for replacement.

I had exactly the same problem. I got mine on 3rd Oct, and after about 7 days of use, I discharged the battery to 0% and it automatically turned off. Since then it refused to charge when power off, and as I have 0% battery, it cannot be turned on, making the phone totally unusable!
I finally managed to get it work again, here's the steps if you also find your phone dead.
When 0% battery and auto power off, if you press the power button, the LED light should flash quickly a few times and off.
Now press and hold the power button and when LED is still flashing, plug in the charger (use wall charger not USB on PC). You should remain holding the power button, otherwise the LED will turn off and no charging again.
After about 5 min, it will be charged to a minimum amount required to boot and the screen will be turned on. Now press the volume up key while still holding power button to reset the phone.
I saved my phone just like this, but even now it still cannot charge when power off. Searched this forum and some say it can be fixed by changing the chargemon file? It would be much appreciated if someone can share it.
Thread moved. Please ensure you post in the correct sections in future as all questions belong here in Q&A.
Thanks

Just to inform you that in the end I have sent my phone to the service center and thay had to open it, remove battery and connect it again.
After that it was possible to charge the phone when switched off. I got it back now and it still works OK. Hopefully it will stay like that.
Shame on you SONY

I bought my XPERIA TX today, I have the same problem.the most issue is when your phone is off then it will not charge at all and LED charging will not work.
You have to switch on the phone and then it starts charging.
This is a big fault of SONY and now I understood why SONY is loosing reputation in mobile market.
I have the latest firmware of 7.0.A.3.220
Like 2 weeks ago my xperia t wouldnt charge too. Fix it then like they said here with a hard reset, volume up and reset. But yesterday i had the problem back. The charger was like on and off cause my notification was busy saying "unplug from socket to save energy". I unplugged the charger from my phone and like 3 seconds later it was BOOM, with a nice flash and my charger died taking out a fuse too. Luckely i just took out the charger, dont wanna know what could have happened if my phone was still on the charger when it short-circuited.
So if you have the same problems.. watch out!
AW: Xperia T won't charge when switched off
Hi, i had the same issue with my Xperia T.
Disassembleing the case and disconnect the
battery for a few minutes solved the Problem
in my case.

How to open the TL?
I have been looking for a way to open my TL can have you any clue as how to so that? I need to remover the battery like you said to get the phone to start charging again.
Get It Replaced!
If your phone is doing this either call Sony +1-877-7XPERIA (1-877-797-3742) and explain what is going on. You're going to need the info from the pull-out tab found in the SIM/SD bay. It will take a few weeks and some Shipping money. OR your provider will probably replace it for free if you can get it to fail infront of them. (PROTIP: Let it die while using it and do not plug it in for a while)
Your phone will very likely get worse until it fails completely. My experience is here: http://forum.xda-developers.com/showthread.php?p=43383759#post43383759
Your phone SHOULD charge like every-other phone. If it is acting funny get it replaced ASAP
I keep coming back to these threads whenever my Experia T is acting up again. I finally bit the bullet and went the hardware way as described in other posts in this thread and also in a comment on Youtube https://www.youtube.com/watch?v=KWox7kCygRE
"In the end I fixed this problem by removing the back cover (one screw in where the SIM card goes) and detaching the battery supply from the phone. After a minute or two I reattached the battery supply (its a little yellow tab beside where you plug in the charger) and put the cover back on, plugged into charger and it started charging as normal."
It's surprisingly simple, to be honest.
Did you manage to modify the chargecom file to enable charging while in sleep?
Cheers

[Q] Phone bricked, red led flash twice

So I have my Z1 for 5 weeks now and I used some times in my pool in home to take some pictures, I've always been cautious with the flaps and everything, I even immerse it in rice overnight when I use it in water just to be safe. Today I used normally, took some pics with girlfriend, everything worked great, after taking the pictures I left it on the table and about 1 hour later I tried to use it and it was blank (me and the phone were completely dry by that time). If I connect to wall charger or USB the led flash red twice and then blanks. I'll leave overnight charging now but I have no idea what to do. Tried turning off using the red thingy, turning on holding volume up or down but nothing works.
Can anyone help or I will have to send it for warranty?
Oh, and I checked and not a single drop of water entered the phone (apparently).

You seem a little paranoid about water, if water had messed your phone up you probably wouldn't even get a red flashing light (as the motherboard would be fried) so you don't need to worry about water damage.
Firstly, presume everything you had on your phone is now gone. Sorry!
Follow these simple steps:
Press & hold the power button and volume up until it vibrates 3 times, then you can go ahead and try to turn it on. Quote me when you reply so I can see it.
Could you also plug it in to your laptop, does the computer read that a device is being connected?
If that doesn't work, we'll try some other stuff and explore some threads! Lots of links for bricked phones. Sounds like it's bricked..

Good thing it's not water!
Did it for over a minute and nothing happens. I've tried that earlier too.
Plugging it on the PC makes the sound of device connected, the red light turns on for a while (about 2 or 3 seconds, no blinking) and then it turns off with the sound of device disconnected.

I've already tried some solutions there and will try others now.
PC Companion won't detect phone. Same with Update Service.
Worst case I'll leave it charging for 12 hours. Thanks for the help, I'll come back later with some feedback. I'll probably get in touch with warranty tomorrow morning.
I'm experience this problem with xperia z after washed the phone. I thought is water damage so I'm just leave my phone. Buy new xperia Z1.... But after 1 month i check back my phone surprise!!!! Is revive again....
Almost 12 hours on wall charger and no sign of life. Still just blink twice the red notification light.

Try all the steps again, otherwise I really not sure what's happened. Some people report days later it comes back on, etc. Hopefully someone else may have an insight to what's happened, but personally I don't think your phone is buggered.
Has this been resolved? I just ran into a similar problem with my week old Xperia Z1 Compact. It was working fine until one afternoon, it was hot and wouldn't turn on. Got the blinking red lights and won't charge. Also won't do anything with the Power and Volume+ Combination.

Bricked Z3C, help :(

Hey guys, i had some serious trouble here. My Z3C is now bricked (I'm not sure whether it's softbricked or hardbricked). The Rom is stock. I plugged the charger (magnetic) from 5pm and I went out for some works, and 3 hours late I returned home and found out that my device couldn't turn on. I've tried many ways like combo VL+ and Power, or Reset Button, but useless. Can you help me with this, thank you so much.

does your pc recognize the phone when you plug it in w/ usb?
if not, then the phone is most likely dead and your best bet is to take it back to the store for a repair/replacement

well i've brought it to the store already. They connected it to PC, then the Sony/Xperia logo appeared on the phone, but the device still .... I don't understand, I used the stock ROM, no root, no bootloader,... but this brick problem still happened. And after scavenging the internet for solution, I found out that there were many users had this problem like I did.
hopefully my device will be fixed without being teardown or the waterproof ability will become weak.

well if the phone responds when connected to a pc then it's not dead, which is good, so you can try to reflash the stock rom with sony Emma

Well my phone is now awake, after a electrical stimulus process. The technician said my device's power was weak. Maybe I should buy a Z2a to use along with my Z3C, well, for precaution purpose.
And I used the stock rom all the time, and I still didn't understand what've caused this problem. But thanks for your great help man. I am really appreciate your support.
I'm really curious, what magnetic cable were you using when this happened?
Was it some cheap magnetic cable or Magnector X or some other?
what the heck is "electrical stimulus process"?
mine gone dead just after 2 weeks of usage. the service center mentioned that it was the motherboard and battery failure. so i guess the best part of the phone is the lcd, huh?

What he probably meant is: if your battery is completely drained so that the circuit of the phone does not even recognize the battery anymore as to allow/start charging, it often helps when you connect the battery for a short time (few seconds) directly (without the circuit in between) to a power source/charger. This bings it back to life and charging it in a controlled manner via the phone charging circuit is possible again.
Well, in my case, my Z3C battery wasn't completely drained. I charged it when it was 17%, then I went out for about 3-4 hrs, and when I came home, the problem happened.
The store technicians figured out that my battery was hibernate, so they used high voltage electric to charged it, then it came back to life, just like we use electric shock method to save people.
Does it make any difference what is the charger?
well, I have just had the exactly the same problem.
And I can tell the magnetic charger cause this. I plug in with 65% battery left ( I charge it overnight as a habit) and In a morning it's completely dead ( like anyone who has this problem ). I was so panic ...
It could be the magnetic charge draw the juice out of the battery and make it completely drained instead of pump power to the battery, I guess.
can you please specify how to bring it back to life please !! thank you !!!!

Z1 Sudden Death!

Hello!
Yes, it's right. I guess it's my turn to get the sudden death of my beloved Xperia Z1.
It's dead, but I don't think it's completely dead and I'm hoping for some help from tech navy's around here and from other people who got the sudden death issue so here's what happened:
I woke up early in the morning at around 8 am and the battery was at 9% and I had no time to put it on charger because I'm in a hurry, so I said I'll put it on charger in car same as always. I use the magnetic cable that I removed from the dock (cuz my sis lost my charging cable, I have to use my magnetic one every time) and I almost always charge my phone in the car with that cable. The phone was working perfectly so I locked the screen and connected the magnetic charger and the charging light didn't come on so I wanted to check if it's charging.... and found out that it's dead (no charging LED, not turning on, no Power + Volume up vibration, no nothing) so I went back to the house and put it on my mother's charger (Micro USB) and got a red LED light as if it's charging, but it's not. still doesn't power up and everything and yes, I've tried the reset button near the SIM card, nothing wants to work.
I took it to Sony service center later that day and they said it will take 3 days because of the traffic they're having, and I have no warranty because I bought it on release which is more than a year ago. After 3 days, they told me that it's a motherboard problem and it got water damaged (while the last time I put it in water was about 2 weeks before that day, and he saw that the white thing is red) and it can't be fixed pay some money and take a new one (just phone no boxing no nothing) and I said no thanks and took the phone to another shop and he checked it and told me that he can't fix it.
I cracked open my phone and I can't see any water damage in it, everything seems to be perfectly fine. I've tried everything I could think of, everything I read on the internet, but nothing seems to work, and the pc doesn't even notice that I connected my phone, I've tried connecting it in fast boot, and flash mode, but nothing works it just keeps the red LED light on. Disconnecting the batter didn't help at all.
I called Sony service center and asked them if I can buy a motherboard from them and they said that they don't even have replacement parts for any Z series phone because they're not authorized by Sony to repair the waterproof/resistant Z series phones (The service center here isn't Sony, but it's an authorized service center by Sony) so at that point I lost hope to get it repaired.
All that happened back in January, but now that summer is here, I want to fix it somehow. But I have no clue where to start, and I'm not sure how to confirm that it's the motherboard that's damaged. is there a way to find exactly where the problem is? I have a soldering iron and everything needed to repair the phone, all I need is to know where's the problem! I can buy parts off of internet, and I will if I need to, but I'm not gonna buy a whole motherboard from ebay because I simply can't trust that motherboard.
Sorry for the lengthy post, and thanks for any help you'll give.
Regards,

Bump
Bump?
leave your phone for a weed and try to charge it . if your phone still led light I think your battery die not your phone .
Your battery is dead, if you have taken it apart already just buy a new battery or buy a micro usb lithium battery charger from ebay and hook it up to your battery (by itself) I posted about my experience here http://forum.xda-developers.com/xperia-z1/help/red-led-flashes-charging-solution-t3141345 If you have access to voltmeter you can check the battery voltage, it is like 2.6v or there abouts. Your phone will not charge a battery this far gone.

I don't think that the battery is dead, because:
1- I get a STABLE red light when I put it on charger or connect it to PC.
2- I've tried a method that's said to revive a dead battery on a Z1 (or Z series) and it didn't work.
3- If it was really the battery, then this should've worked! But no, When I connect the motherboard with test point properly connected, the PC just doesn't recognize the phone.

I followed all those methods as well and none worked for me either. Measure your battery voltage with a voltmeter, it is the cheapest way to verify if the issue is battery or something else.

Hello!
I finally got access to a multimeter today and checked my battery's voltage and it was about 3V so I can confirm that the problem is not the battery.
It must be some kind of hardware problem, and I don't think that you really did try the test point fix and you just said yea yea bla bla YOUR BATTERY IS THE PROBLEM! No, it's not.
Any other suggestions?
Thanks!

3v is still to low in my opinion

I've charged it, and still not working.
Bumping cuz I want my good ol' Z1 back
I've experienced a "sudden death" once, it was really scary to me.
I've flashed a custom rom, rebooted and went to bed directly without waiting "android is upgrading" or whatever.
The next day I saw that my phone was not opening. There was no red led to indicate low battery, I plugged to charger for some seconds and didn't see a red light to indicate "charging" so it was weird to me. The solution was to charge it for more than 30 minutes and afterwards it went to 1%! Maybe you should try to charge with the cable like normally and wait for a while

Hope it works! 30 minutes was so long and worrying though :silly:

Nope!
You obviously had a dead battery, and I've already left it on charger for 2 continuous days.
I clearly have a hardware problem. Probably a dead chip as the phone died the moment I connected the magnetic charger.

If u disasassembled your phone then simply disconnect battery, connect phone to pc (with disconected battery) with pressed volume button down, if phone working u should see blue led light (flashmode)-if this happen then your battery is fault (maybe not, try to flash stock rom if u see flashmode), if not then it is mainboard.

I don't think that you actually read the first post, but no problem.
The computer doesn't recognize the phone at all, with or without battery. And I've posted a link a couple of posts back that leads to a "hard brick fix" thread and even that didn't work for me.
Anyways, I just tried what you told me to try, but no. No flashmode, no fastboot, no nothing.
