[V - LT25i] SOD, heatissues and random reboots.

How's the progress on finding out what is causing all these issues? Anyone got any idea apart from turning off WiFi?
I've tried AOSP (kangXperiaProject 4.1.2 r3), The SuperSport version, and in the 4.1.2 i didnt have the SOD problems, but some other missing parts / issues made me go back to stock.
Now I'm having issues with it rebooting basically every time I unlock the screen. (reflashed with my own FTF, and relocked the bootloader to stock).
Any ideas?
Other XV dosnt have SoD with the stock 4.1.2 ROM, i think is a hardware Problem.
Some SoD users become a new motherboard(contact the sony support) then is the SoD go away. But the sony support make mostly the firmware new, but that dosnt help.
I have my SoD XperiaV send back to the dealer and become back my money. I wait and buy ist to an other time, i thing some charges of the Xperia-V are bad.

Random reboots

Hi. I hate this phone.
After three months since I got it, one day it turned off by itself and never turned on again. I sent it to customer care in the store where it came from, and they changed the battery. The moment I got home, the phone had the same problem. So I tried Sony PCC to repair it. It turned on, I installed some apps and suddendly it turned off again. I suspected it was because I deactivated bravia engine, but I'm not so sure that's the problem. Anyway, I decided to downgrade to Android 4.1 version .254 with root. Now the phone seems to be working. But sometimes it just reboots by itself. It happened once when I was scrolling Facebook, and twice when I was using Chrome. It just reboots and restars like nothing happened.
Is this a Ram problem? I can't put the latest firmware because the phone doesn't work AT ALL with it. What can I do?
Hi. Try to flash 254 fw with flashtool. It could help.
Flash the latest FTF via Flashtool
I have quite similar issue on my Xperia SP (random reboots). I have latest official rom installed via PCC.
Try switching off Stamina Mode and see if it keeps happening. It seems to work in my case.

Wifi/Bluetooth Won't Turn ON

I recently updated my HTC One M7 from Android KITKAT to lollipop via OTA.. Before the update my wifi/Bluetooth are both working fine, at the first few hours after the update, my phone seems to work just fine then suddenly my wifi/Bluetooth are not turning ON, phone restarts randomly and stuck to the HTC One logo page. I search the web and follow the idea of rebooting to safe mode, rebooting to recovery clear cache/partitions and hard reset my phone many times but none of these works. I decided to revert back to kitkat (RUU) but still no working wifi and Bluetooth. I even tried to run the jelly bean which I believe is the original version when I first bought the phone, to my frustration, I STILL DON'T HAVE A WORKING WIFI/BLUETOOTH. Any solution?

Sony Xperia C6603 auto reboot

I have a problem that my phone automatically reboots itself everytime my mobile data is on even when it's not overheated. My phone is using android 5.0.2 build number 10.6.A.0.454 (HK version), kernel 3.4.0-perf-g8fa3dae that comes with it, and it was rooted.
This problem only happens since I update to 4.4.4 or later versions. It never happened on 4.3 (originally installed on the phone).
Anyone got the same problem or any solution for this?
Did you try to wipe data/cache/dalvik?
did you try to fix permissions?
both with recovery

I am having the same problem, it's rebooting it self only and one thing i measured which is actually strange that while it is under charging then it does not reboot itself so what should be the problem??
Help me to sort out this ASAP.
I had also that issue recently. After so much rom flashing i decided to try to replace the battery and it worked. Just try to replace battery may be that wil also work for you guyz.

Random Shutdowns and Reboots?

The other day, my friend gave me his old Xperia T as it had started to act up and eventually stopped turning on entirely. I took it home, downloaded a generic 4.3 ftf and flashed it. Although the phone now boots, it occasionally reboots or just flat out turns off (without warning - the screen just goes black and I have to turn it back on again). I have tried flashing a few different ftfs, and the problem still persists. Does anybody know how I can stop this and finally be able to abandon my Arc S for good?

I'm fairly certain my problem is just with the battery, as I've installed a 4.0.4 ftf,a 4.1.2 ftf and a 4.3 ftf and the problem is consistent on all of them. Once I've bought a new battery, I'll let you know if the problem still persists.
