Hello, Its been a long time since I don't ask anything on the forum, but in this occasion I haven't found any solution to what's happening to my Xperia Z, I'm gonna do my best to present the issue.
A couple of days ago I updated my Xperia (unlocked bootloader) from Existenz 1.5.5 to the latest 3.0 and the phone was completely fine for 2 days until it started shutting down by itself constantly and with no apparent reason, so I started to get worried, the first thing I did was try and reinstall the ROM thinking that I had some something incorrectly, I has no luck with that, on the contrary the phone died on the middle of the installation and it got bricked. My next step was to try do do everything from scratch, flashing the stock rom 10.5.1.A.0.283 to root it, install recovery and try flashing the Existenz after. I managed to do everything with lots of unwanted shuts downs in the middle but I managed. Unfortunately the phone kept on having the same problem so my last option was to try and use the Sony bridge on my mac to try and make a factory reset but it didn't let me because it detected the unlocked bootloader so I relocked it with flashtool, after that I tried again and it worked, it installed the official stock rom .101 and guess what..... same issue again, when I try to turn the phone on it shows the sony logo and turns off, if I try to turn it on connected to the AC it turns on but if I start playing with the menus and options it disconnects again, ofcourse if I turn it on connected and once it's on I disconnect it it shuts down almost instantly, At first I though the problem could be software, then hardware so I tried to check the battery status in the service app and it said good battery health so now I'm completely lost.., I've found this: http://forum.xda-developers.com/xperia-z/help/hardware-fix-xperia-z-charging-booting-t2760911 but I don't know if thats my case. I was gonna go to a sony store and ask them what could be the problem, but now I'm living in Brazil and it'd take lots of time and money to get ir fixed here.
I really need help here, sorry if I posted on an incorrect place.
I just found a video of someone with the exact same problem, in case in helps: https://www.youtube.com/watch?v=zkvLchJ_0oU
UPDATE: I rooted it, install recovery and once im in recovery it doesn't turn off by itself what tells me that may not be a hardware problem, at least not battery related, all this just makes me feel more confused!!
UPDATE 2: I rebooted the phone to load the recovery again and the battery indication went from 89% 2 minutes ago to 11% this second time, maybe it's hardware after all..
Battery.....
TapaTalked from my Xperia™ Z (C660²) running Ultimate PureXZ Ultra!
I seriously don't think is the battery, I think it's something related to the energy but I'm not sure what. As I said before the battery went from 89% to 11% quite fast but when it was at 1% it stayed there for hours, if it was the battery wouldn't it had turned off? after it finally turned off I left it charging for about 12 hr and today morning I try to turn it on without it being connected and no luck, it kept shutting down after the Sony logo. Sometimes when I turn it on with the cable connected it loads the OS and I unlock the lockscreen, diconnect the cable and extraneously it stays on just with the battery power, I manage to put the ScreenOff timeout to 30 mins and it stays on all the time, as long as I don't do certain things like opening the camera, phone or sometimes it just randomly turns off from anywhere. I know it's not the rom because I've tried 4 different ones including the official installed by Sony Bridge....
If the issue is software related what could it be?? the bootloader? the bios power management? battery stats? maybe restoring TA backup(because I just relocked the bootloader using the option o flashtool, not flashing the TA backup)?
I'm concerned about buying a battery, installing it and seeing no change as I've read happened to some guys with the same problem.
I really like my phone but after this I'm not so sure i'll buy another Xperia because this has happened to so many people and apparently there's no solution, my phone is out of warranty and I life in a foreign country (Brazil) so you guys are all I have...
Same Problem Here ... Impossible to flash either from fastboot or from CWM or TWRP
Hi, I am having exactly the same problem. I was trying to revert to stock kernel from CM10.2 and was following one of the many guides here on XDA. The phone was not passing the «SONY» Logo, and immediately after such logo it simply went completely black and the phone is off. After two days of trying several things, including Fastboot of Stock ROM, fastboot of different boot.img files including Doomlord, using Sony Bridge for Mac, all of which did not solve the issue, the problem now is that when I try to flash any ROM, the flashing operation begins and then after approx 15 seconds the phone goes black and switches off. The battery is at 82%, so I am quite sure it is not a battery problem.
I am more and more convinced that the internal filesystem (or simply RAM) needs to be formatted at low level from scratch.
The only problem is that I do not know how to do it: how to do LOW LEVEL Formatting of RAM? Any instructions out there?
Any other suggestion?
Thanks

It seems like there's no solution and I don't think my battery is broken so I won't try the Hardware Fix since I don't wanna break my phone more than it already is, tomorrow I'll try to go the a Sony service store and see what they think the problem is, since I unlocked my bootloader and relocked after I think they will be able to see this, I think it ain't gonna be a problem because my warranty was void long time ago, and it's 1 year anyhow.... I hope they recognize it's a sony's fault issue and they decide to fix it with no cost, very unlikely but hoping is free gcecchini, i'll keep you updated, also if you find a solution let me know.
Hi Ringox!!! I'm having exact problem as your's.. This all started when I upgraded to 4.4.4 . First it was giving some weird problem like when opening camera , the phone shuts down. Then a time came the device was not charging.. The device boots up when connected to wall charger. But as soon as charger is removed the phone shut's down. Without connecting the charger when I tried to power on, it shows sony logo for 1 second the shut's down. I tried installing every stock rom , custom rom, kernel etc and it didn't solve the problem. I also bought new battery but same problem. I don't think it's software or hardware or battery problem but may be bootloader is corrupted. May be when we flash bootloader ( as in samsung) we may solve this problem. But I cannot find any tutorial an instruction to flash bootloader.
Also from quickstyler thread I can confirm that I have same problem as him, the sony mobile battey test app shows same error battery temperature -30 C . But his hardware fix didn't work either.
By searching for the problem on youtube, xda, google and other sources I can confirm 1000s of people is getting this problem ..
Please developer and member , help us provide solutions and tips what we can do next...
I have news, after one month waiting for Sony to repair my phone they've finally said it can't be fixed and they said the problem is the motherboard which is approximately 130 dollars plus installation, so I decided to park my Xperia and buy a SGS4. Something interesting that happened is that now the phone starts and sounds, just with a black screen all the time with the backlight ON, maybe they fixed something and broke something else, I don't know. If anyone knows a solution to this rather than changing the motherboard I'd appreciate the answer. I wanna fix it to give it to my mother, but I won't be buying any other Sony smartphone ever again, their service is a disgrace and I couldn't be more unsatisfied with them.
This is a very strange problem. I never saw anything similar in my life and I searched for someone with a similar problem but I cannot find anything. So I am posting this thread, maybe someone here knows what I should do.
This tablet has been riddled with problems, but this one makes it close to useless. I had several problems since I got the tablet where it won't wake up after sleeping and you had to reboot the thing, where the dock is not available after sleeping and you have to undock and redock it, where the battery drains while sleeping etc etc. Annoyances but I can live with them. I know there is a fix for the dock and you have to send it to Asus, but shipping is expensive so I'll learn to live with it.
This problem though.. this is a big one. So just to clarify, the tablet is rooted with the original 4.4.2 ROM. I did not make any changes in the past week. Yesterday morning, I woke up and used it normally. Later that morning I unplugged it from the charger and that's when I noticed this problem. So while it is connected to the charger the tablet will function normally. After I unplug it the tablet will freeze after a few seconds, reboot on its own and then it will boot until the icons start coming up. Usually after this you get the lockscreen, but instead the screen will black out. After a few seconds the icons start coming back and the the screen will black out again and so on. This loop will continue forever unless you plug the charger in. When you plug in the charger, the icons will come up and after you get the lock screen (instead of the black screen), and you can use it normally. If you unplug it again, the boot loop starts again. This behavior is the same whether using the dock or not.
I don't want to do a factory reset just yet if I can. Last time I did a factory reset, the tablet would not boot and I had to send it back for a replacement. When I get to the fastboot screen, trying RCK I get the dead Android with the red exclamation, and cold booting does nothing.
Any suggestions please? Any kind of log I can get to help? I can post a video if the problem is not clear.
Thanks.

Hi, to start this reply, I'll let you know that I am no professional at any of this stuff. I am a regular person that has had experience with flashing ROMs and whatnot. In my opinion, this seems like a software (maybe hardware) related problem. So there are a couple of options you have here.
1. Are you still under your warranty period? You could return it and get another one (easy fix)
2. You could try to factory reset, and if it doesn't turn on, rma the tablet (which it sounds like it may be cheaper to just buy a new one anyways)
3. You could try unlocking the bootloader. Then install a custom ROM (kind of risky, but might be less risky than #2)
Overall, you are not in an amazing spot with your tablet. It saddens me to see all the problems with asus's tablets. I have been with them since the transformer prime because of their laptop like tablet makes it easy to use in school, but its always been a struggle staying with their lineup. I have returned their tablets multiple times. Please update when you can

If you have a microSD in the tablet take it out and try to boot it. I have seen the weirdest problems because of a card on the fritz....
Second possibility: Hardware. The behavior (working fine when connected to power) seems to indicate it doesn't get the charge it needs from the battery. Could be that it is going kaputt. It's not totally fried but enough that the tablet does not get a reliable charge from the battery.
Third option would be to reflash the firmware. That would eliminate a software problem. You will loose root if you do that...
Since you're still on the original firmware, I assume you did not unlock the bootloader and rooted with Towelroot - correct?
Whatever you do, backup everything you care about off the tablet now....
Thanks for your replies/suggestions. I could not use towelroot as it was on 4.4.2 (I think I read it is not possible). The bootloader is unlocked. This is my second tablet as I had returned the original one. I tried putting Cromi-X on it, and when I got to the step to factory reset it (using fastboot), the thing just was stuck in an endless loop. I could not even get to fastboot and my PC wouldn't recognize it. All it did was boot to the ASUS logo (and the message that the bootloader was unlocked) and reboot.
So this is the replacement unit and the charging issue was the problem. I say was because believe me or not the tablet is now smashed to bits. Since it must always be connected with a charger to work, I was carrying it around docked as I usually do and forgot that it was plugged in. I have resorted to an extra long extension cord with the charger plugged in to walk around. Anyway I forgot it was plugged in, the extension cord reached its limit and the charger cord yanked the tablet out of my hands and onto its side - screen facing away. I sweared, feared the worst and went to pick it up. The good news is that it still boots. The bad news is that the screen is completely smashed. The back cover is bent at one corner and the glass is smashed at that corner with cracks running to the other side. The touchscreen is not working anymore either. To add insult to the injury the tablet still only boots up with the charger plugged in..so there's that.
I don't know what to do now. I have contacted ASUS for a possible RMA but got no response yet. The thing is I don't feel like spending more money on it given the problems experienced. A screen with digitizer on ebay is about €75..so not exactly cheap.
I guess we can close this thread as it is now pointless. I hope no one has to go through my experience and that maybe it was a one off thing.
Thanks again to whoever replied. I appreciate it.
Hi guys. I have already exposed my problem as a reply on a post with similar issues and it has been bricked for more the one year, I have tried to recover it several time with no luck. I would like to try one more time before to decide to buy another smart watch.
I remember I was playing trying to unlock the watch and I made it working unlocked. Then I flashed the rom but unfortunately I chose a rom for a different watch, maybe LG urban or something, which resulted on a bricked watch. It boots but the LG icon stays for ever.
I have tried:
taping with to fingers at 10-11 and 4-5 hours on boot
swipping finger from 10-11 to 4-5 on boot
pushing the button for ever
trying to find a reset hidden button (seems there is not)
disassembling watch trying to find something strange
no way to connect to any computer. I was able to see computer detecting something plugged on usb but it refused to connect due to errors with usb-device communication (don't remember exactly which error). So nothing to do with adb
wait until charged and discharged
Pretty secure I have tried more, I am writing from a very bad memory
Do you have any advise? is there something else I can try?
cheers!
Try fastboot command during the boot...
Try flashing a new boot image.
Could you advise how to get fastboot? I mean if device is not even detected there's no way to issue commands, right?
No one? So I would have to buy a New one

Try seeking warranty repair?
What do you get in device manager when you connect it over USB?
Charge battery... than Power Off.. Put it it the deep fridge to cool down..
and try to bot after that...
Mine booted.
Greetings, for the first time ever in my life I never experianced getting a Bricked phone, it did not happen while flashing or doing something wrong. I just did a normal flash, it was sucessfull was running the custom Rom there since months. I just woke up grab my phone while it was charging (It was at 100%) used the Instagram app and it randomly froze, I was just thinking it's normal, every Android phone freezes sometimes somewhere , plugged out the battery plug in and tried to boot it up, but nothing no vibration, no lights nothing. After some time, in the holidays I decided to plug in the phone into my PC, I heard noises that my win10 laptop tried to reconize something, so I had still hopes for it that it still works. I heard about that a JIG will may work for it, so I bought one that was "inteded" to be for my S3 Mini GT-I8190 waited for it to arrive and plug it in finally, well you could guess it, nothing happend. I knew a friend who had the same phone and I asked him if I may plugin the JIG inside, all it done was just vibrate and nothing else. On other phones it just works flawless. I tried to look up for a debrick image for the phone but it seems there is nothing like it, like it never existed, only the S3 somewhat got it. The only thing now I could help people is, is how to get your system back while TWRP/CWM/Recovery is still there or get the recovery back while the system is still there. My only option now is create some how a own JIG, buy a JTAG and get a debrick.img but the third option appears nowhere here nor in a search engine (Or maybe only mine).
If you have questions, please aks and don't be shy. The current state of the battery right now is 2.8V (Must be at ~60%)
Hey guys,
I have a problem with this phone. I got my relative's note 8 for trying to fix ( i'm not android expert ).
As she says, for no reason phone freezed and shuted down. After that charging problem started, and battery doesn't show real percentage.
After that i got the phone, and tried to go factory reset in recovery menu. Now phone stucks at samsung logo. Sometimes it stucks at blue screen with "no command" text.
Phone doesn't works all the time also. For example, somehow phone charged %100, after that i tried to open it, it stucked at samsung logo. I tried hard reset, screen off and no more screen. After 4-5 hours it worked again, but stuck at samsung screen again.
I send phone to trusted local repair shop. They couldn't managed to fix also, they reported me that it should be motherboard issue and they can't do anything about it. I don't know did they tried to install stock rom again.
I see no reason for motherboard issue. No water, no big damage or something else happened to phone. There should be a way to fix this and i seek your support here.

I would go with what the repair shop said personally. They certainly know a lot more than I do. Unfortunately things do just break even with no error for the owner themselves.
It is definitely worth trying to flash stock rom with Odin though.

Thanks for your thoughts, honestly i don't expect it to work again, but before throw away i want to try all chances
