Xperia Z "sudden death". Anyone else with this problem?

Hey guys,
Unfortunately I have encountered a sudden death with my Xperia Z yesterday. I had:
- Unlocked bootloader
- Stock kernel
- Stock based rom
- Recovery for locked bootloader, because I was still testing it.
I wanted to try the whitebalance.apk from Xperia ZL rom to seeif it worked or to debug if it didn't.
Anone else had a sudden death or a similar problem like softbrick? Let me know and post as many details as possible.
I've tried everything so don't say:
- Try a hard reset
- Try fastboot
- Try Flashmode
- Try charging it for hours
EDIT: More details:
- C6603
- No LED
- Vo vibration
- Nothing after hours of charging.
Only thing I haven't tried is connecting in a dock, because I don't have one. Black97 told me he solved the issue by connecting to the dock.

Do you still have any led notifications(red,blue,green)?
Did you manage to use the white balance settings?could be the value set burns the screen??

would u pls tell ur xZ is; C6603 Or C6602?
and kernel

Off topic I know, but I bricked by Xperia U by removing the battery through a freeze. It wouldn't boot or charge. But I left in on charge for an hour, and it booted. As well as that, it had downgraded from V4 of a ROM I was running to V3.
On a brick that makes no sense, fix it in a way that makes no sense.

Have you got a old Xperia sitting around? Bring them to us!

I added more details, I've really tried everything, I recovered several Xperia phones from soft brick, so I don't think any of these will help, but I'll connect it to usb and charger again during the weekend. I need to sent it back to the online store on monday.
EDIT: More details:
- Stock kernel
- Stock based rom, slightly modified stock rom
- Unlocked Bootloader
- C6603
- No LED
- Vo vibration

Any Feedback when connecting to PC?
Any Device recognized? I actually think you messed up your CPU/Mainbord somehow... ...or is it a memory/flash problem?
Hope you can solve it

Try recalling what you did before the sudden death, like installing the apk or modifying the framework.

Hello krabappel2548 !
- to understand that not really worth to unlock bootloader !
- XZ is so sensitive that he breaks so fast ?
I know you as a consummate professional ( I do not think it is because of you, rather I go on a platform quite sensitive to the Sony ...)
I bought it a few days ago and I'm going to do some custom rom and kernel for it - but now I remains to think about that ....
Good luck & hope that you resolve the situation :good:
( sure, I need to unlock bootloader first : )

Hey please remove your back cover and disconnect your battery ( batter connector would be there) for 1 min and dn screw it again. Try to switch it by pressing the power button fr 30 secs or power and lower button together fr 10 secs! The phone ll switch on!

Battery cover on the Z is unremovable.
My guess is he just had an unlucky device. I've read about one dead Xperia Z before on another forum so it's entirely possible. Doubt it's related to anything else.

Did you experience any extraordinary heat from the phone before it crashed?
Maybe try smelling for burns or something.

Recover your phone with SUS, i recovered my x10mini several times.

U can remove the back cover by using tork screwdriver

Rooting and flashing roms

Hey,
Looking into flashing some custom roms onto my xperia z however I was wondering what I lose as soon as the rooting / flashing begins?
I remember when this phone out there were problems with flashing where you lost the brava engine and also the drm services. This still the case?
Also can you return things to stock with 100% of everything working again?
Cheers
Scott

You will not lose anything just from rooting.
You will however lose your drm keys and Bravia engine if you unlock your bootloader.
There's loads of info regarding this so search and read.

i thought i saw that they have a rooting apk file but ive never heard of it working, u can jus use a friends pc and root the phone though because the rooting files aint even large or take up space

Thanks. I will go ahead n do it on my gfs laptop whenever she brings it. I wish there was an apk but that's fine.
Sent from my LT30at using XDA Premium 4 mobile app

The apk is called Framaroot, but I don't know of it's confirmed working on our devices.

I'd suggest you to wait for a laptop rather than attempt anything not confirmed, because if something gets messed up you can't fix it without a laptop again. So enjoy the bloatware!

if you have a ta backup you can unlock and relock the bootloader without any problem like the first day. even the sony cant realize that.but if you dont want to unlock the bootloader i think iHackers and RomAur are best.fast and stable
but you may have some issues with Xposed Framework (which is really handy) in LB.
but these two i think are the best based on stock roms
for note,I'm using iHackers v4.1 with unlocked bootloader

Ya I have many ta backups. But I shud unlock only after 6th Oct,my lifestyle is too dangerous to ignore warranty (I KNOW SONY CANNOT IF I RELOCK,STILL.. As I have no personal pc..ll buy in Oct)o thanks anyway.. M downloading ihackers 4.1 minimal version now.

If you relock bootloader via TA backup, no one can notice that .means sony cannot realize it and your warranty stands.
and i think,i think,if i'm not wrong, rooting the phone will break the warranty .. ! again i'm saying, i think

Sorry, I just saw the rules..no best' rom thread allowed. I tried to edit but in vein! Sorry...
Hmm...m searching Sony.Co.in about this pal... "Does root void warranty? "

The battery drain was due to bug in Play services, recent update has resolved the issue to a certain extent
If rooted then you can install wakelock Xposed module.
For keyboard lag there was an update for the keyboard few weeks back try updating and see whether it resolves the issue.
For SD card issue check this thread

No I didn't root my phone coz i dont want to void my warranty ... Is der any other sd fix for non root user??......

There you go:

Does rooting void warranty? How's anyone ever gonna know it was rooted incase the warranty is going to be needed? I doubt they analyze each phone that much.
Regarding the keyboard, sometimes it lags a bit. Especially if it has been running for 24 hours or something. I've made a Tasker profile to "reboot" my keyboard app every 8 hours to keep it responsive.

Battery drain - The battery drain is caused by Google Play Services, which is not under Sony's control.
Keyboard lag - I had this to start with. It went away after a few reboots, along with most of the other lags in the settings etc.
SD card write - Not a bug, or anything that will be fixed by Sony. External SD permissions were changed by Google for security reasons and OEMs had to implement them or risk failing the certification for Google apps. Root and use something like this app to make the external SD work the same as before.
Edit - I see this has already mostly been said. When I entered the thread it only showed me one reply, then the others showed up after I posted. Strange. ?

It's possible that OTA updates might fail, as a system file is modified. You will always be able to use PC Companion/SUS to update though.

OTA updates might fail, or they might work. It's hard to say 100% either way.
When starting an OTA update, a check is made on the system partition of your phone to see if files have been removed or modified. It depends what is checked during this process. I have no way of knowing what a future OTA update from Sony will check, so we'll have to wait and see. ?
