[Q] Random reboots Xperia M2 - Sony Xperia M2

thanks for and help

I don't have reboots. Roote, with Locked bootloader.
How did you get reboot? What you did/install on your phone? Try doing factory reset of repair with Pc companion.
Good Luck.

I've tried Pc companion and a factory reset through the phone but it still keeps cutting out and rebooting when ever the screen goes off, its only 2 month old. only normal apps from the play store have been installed not any from the internet downloaded.
Thanks

Try to take logcat to see what is the problem. Download Android sdk tools, in tools folder you'll find monitor.bat, there you have logcat option.
If you have warranty just take it to Service.
Good Luck.

Finally i got it solved. Only when i made
the 3ª hard reset but this time with the
"backup data" settings turned off and
the "Automatic restore"turned off in the
same settings, it worked. I think some
aplication update was causing the
problem and it is happening in a lot of
M2 devices. It is a shame that we can't
downgrade the apps frm the store.

Which app was it then?, I use both those functions just fine so can't be using it.

i have the same problem just it won't give me the factory mode
what should i do?

[Solved] Hard bricked my Xperia J...

Hello everyone,
Yesterday I've tried to update my Xperia J to the new Jelly Bean firmware, but before that, I've done a full wipe and format system and cache through CWM. After that, I reboot my phone and it never goes after the Sony logo. I've tried to repair it with PC Companion, SUS and Flashtool, but everytime it starts to flash new Rom, the green led goes off and nothing is done.
Is there any solution for this, or should I go to the store and pray that it isn't to expensive to fix it?
Thanks in advance.
Anyone have a suggestion?
Re: [Help] Hard bricked my Xperia J...
Its not hard bricked.Its really normal for green light to go off while flashing ftf.Just wait for the flashtool to complete preparing files and then connect your phone in flash mode(green led) after the prompt appears.It will instantly start the flashing process (and yes, the green led goes off as soon as flashing starts so dont worry).
You may also experience a strange problem where the flashtool gets stuck at 0 percent. You can fix that by trying some older version of flashtool.
Good luck

Thanks a lot for your help, I'm really getting stucked at 0 percent at Flashtool. I can´t even repair it with PC Companion, that's why I was afraid that is was an hard brick. I'm going to try with an older version of Flashtool as you've said.
Thanks again.
EDIT: I've tried with an older version of Flashtool and still no luck, always getting stucked at 0 percent. I read somewhere that my problem must be that my phone at this moment don't have any operating system and that probably I couldn't fix it at home. Is this true or is there something more I can do?
Re: [Help] Hard bricked my Xperia J...
Well i used to get this problem with my flashtool.Installing an older version did the trick for me.You can try flashing from some other system

Unloked bootloader????

Re: [Help] Hard bricked my Xperia J...
If you got unlocked bootloader then you can fastboot flash fxp kernel followed by the rom itself.This will atleast make your device functional again.

Unfortunately my bootloader is locked.
I will try again, but this time on my computer here at work.
EDIT: Still no luck in another computer. I guess I will need to go to Vodafone Store at the end of the day and see what they can do with my phone.
Good news!!
I've installed PC Companion here on my work computer and it repaired my phone. Probably there's some kind of problem with my computer at home. I'm already flashing Jelly Bean normally with flashtool.
Thanks a lot for your help balboarocky.
Use Flashtool for this

Really hard Brick sony xperia J
under clockwork mod (after using int for installing cyanogen) i want to erase some data because my Cyanogen install was bugged (i forgot to Md5 checksum, so the files was maybe corrupted),
but i was very tired.and it's more than possible than i erase boot or systeme,
since that NO Led, No fastboot or Flashmode connections,
Do you think my Xperia is dead from dead (tm) .
Edit : to make the phone react and avoid bootloop i have to remove the battery and use it like the "power button" to take my phone in Flashboot, reflash Cwm and my phone work again ....

[Q] Z3 D6653 Stuck in Sony Xperia Startup Screen

Hi All,
I tried to update the system software to Lollipop via PC today. in the middle of the update an error occurred saying internet connection was not available (in fact there was no problem with the internet connection). i followed the instruction to re-connect the phone to the PC via the USB cable. now the phone stucks at the Sony Xperia bootup screen and when i connected my phone to PC via the Sony PC Companion, it only detects my phone as "Sony/Sony Ericsson/Tablet" and not Sony Z3 (D6653) anymore.
Anyone knows how to resolve the issue? best if i can continue to update to lollipop, or if not restoring to the old setting would be great too.
Thanks Guys
Cheers

i tried that but it doesn't work it gives me an error when i connect the phone
and my bootloader is still locked
Can u still access the recovery?
I'm assuming yes then why don't you try a custom ROM.
Just search the XDA Forum. Your ll get official ROM as well.
perss volume up and power for a while
It will shut down your phone
Then, dont connect your phone to pc
use xperia companion and choose repair
Finally press volume down and connect to pc
I tried that and it didn't work but i fixed it
i can't access recovery or use xperia companion because it gives an error but i fixed it by downloading an ftf and flashing it with flashtool i then updated my phone to marshmallow with xperia companion, but thank you for replying

Bricked Z5 - keeps restarting while flash

Hey there
i have some serious problem right here:
I somehow got stuck in a Sony bootloop after trying to flash a ZIP file with twrp. After that I tried desperately to wipe everything possible, so I somehow deleted the OS. However, Flashtool does still recognize the device and I can still enter twrp. Sadly, when I try to flash a stock rom via Flashtool the Z5 keeps restarting on is own thus interrupting the flashing. What is the problem? IM really desperate right now
Help pls
You need xperia companion software fix.
