[Q] Sony xperia z turns off without any warning - Xperia Z Q&A, Help & Troubleshooting

I have sony xperia z model c6603 kitkat. It used to turn off without any reasons. After it turns off, I cannot turn on the phone without connecting the charger. After connecting the charge it shows that the phone has no charge even if it has enough charge and after pressing the power button it turns on.
I was so frustrated I rooted the phone, unlocked the boot-loader and flashed the original ftf of sony kitkat using flashtool just in the hope that I will not face the same problem. But I again faced the problem. I even tired flashing AOKP but the phone always turns off without any warning.
At the moment I have flashed cyanogenmod but the problem is always here.
So, I have come to the conclusion that it is not the problem on Sony firmware and next version of android(if they release) for Sony will not solve this problem. My question is do any one have any idea what is the problem? Is there any kernel or app that will help me?

Xperia Z; Dead problem After update to .434

Hi
any report about death problem of Xperia Z after updating new firmware (.434)?
Thanks
:good:
That title of yours is a bit off, you make it sound like you have a dead phone after updating
Hehe
No, i just wanna know if this happened or not.
If problem solved completely so we can use it more and etc
However i used it alot before update
Sent via my Sony Xperia Z | C6602
As far as I know, Sony hasn't received any reports of death phones due to the software issue of 350fw with the new 434fw
Sent from my C6603 using xda app-developers app
That is good news.
Can not wait for 4.2.x to release, did download krab his 434 NL FTF file just incase I get software problems.
Kind regards, Stefan.
But since the update after my nightmare began, First, ROOT many times without success (this is my problem), to complete the ROOT, try to go and get LINK2SD, but every time you create a EXT2 restartafter will not be able to enter, just kept restart, need to be removed the SDCARD, Anyway, if sdcard including not turn on, and subsequently I leave a message in the official website, and they told me to try a factory reset and clear memoryeverything, I have tried, but resolves containing the sdcard normal boot, but often a memory file something will restart to now, I have not yet been solved, I am thinking how to completely cleanpainted on the software, who can teach me how to clean, I also tried FLASHTOOL, but I try many time, it just is hold on at flash strat point, then over 30mins , is still....... i very bad lucky

yes like your phone died with the 434 update ?
there seem to be quite some reports of a damaged kernel version with this update that uses a lot of cpu in standby and damages it through heat.
Updated the phone a few days ago, powered it off today and it did not boot. Now its in repair

Sleep of death is still present in .434 Phone was fine for a week after updating, but the problem has happened once a day for the past 3 days. Wake up in the morning to a dead phone. Able to perform a reset with power + volume up.
Not happy, where's this fix we were promised! Sony never said .434 was to fix SOD, it was all stupid rumors.

i had the exact same probleme with my asus transformer pad for 5 months and asus delivered several updates promising to fix the probem, but it did not work, this happened with android ics 4.0.3.
after half a year they managed to fix it.
so until it's not completely dead, just wait for a working update.

[Q] Xperia X8 brick?

Hello everyone!
I'm trying to fix my phone for 2 days still no success.
My problem is:
When i turn on the phone it does nothing,only the screen lights up for like 2-3 seconds after that it turns off.
It keeps doing it again and again until I take out the battery.
It cant even show the sony ericcson logo.
Battery works i tried it with another phone!
PHONE WASNT ROOTED OR FLASHED OR ANYTHING LIKE THAT
Solutions i tried :
Sony ericcson update service - no use
Flashing original firmware with flashtool - no use (btw flash mode works as long the flashing process works like charm)
Hope someone can help me out because there is no more warranty for the phone
Thanks in advance
Erik

Probably a hardware issue, I guess it is time for a new phone.

Try to do factory reset or flash stock rom. If not helped that means there is hardware issue in CPU or battery

[Q] my sp only turn on while charging

I have an issue, last nite my sp was normal, but this morning facing a problem
My sp cant used when not connected to charger, when i open an apps it becomes bootloop,sometimes not just boot loop, its sudden shutdown by it self.
But when i connect my sp to the charger, its become normal, i can used it for anything, i try ubl and use custom kernel but still got the issue.
The day before its happen, my sp facing big drain battery, and i do recalibration on my battery using an app from playstore.
I need a help here, is this battery hardware or i can do something to fix it?
Happened to me once, turned out to be a hardware problem, had to get it replaced. Have you tried wiping everything and flashing stock firmware? It may just work!!
Not yet, im in stock 4.3 existenz ultra 4.0.0
I think its same as stock rom.
