Xperia Z Wont update

[Florin1]

Hello!
I just registered to this forum, but I have been checking it since the beginning.

I've got a problem updating my Xperia Z.

I followed all steps that Sony PC Companion told me to do, but i keep failing.

I've got to shut down my phone- Wait for 5 seconds -Plug the USB in while pressing the volume down button.

When I try the last step the LED goes Red/green really quick, and after that just nothing happens.

I also get a notification (translated) If you fail updating, don't worry! just begin again @ step 1.

I have tried it like 5 times, but it wont succeed,

Sorry for my horrible English :smileyhappy:.

Thanks for Reading/Helping!

is your phone a locked bootloader or unlocked bootloader? if you unlocked it then that would wave your warranty, just asking this to see

mu phone is unlocked.

I manage to do the update by using diffrent computer, sems that this problem is a computer problem with old software , not a one caused bu the phone!

I tried to update my phone.
But it didn't install completely.
It will just take not more than a minute and then will just turn on.

I tried doing all that is mentioned here and still my the PC Companion won't start the process. I have xperia M. Is there any other way round? I have already repeated the process six times, and yes, I held the volume down button till 3-4 minutes. But still the update did not start. And that power button + volume up button thing does nothing on my phone. Please help!

Hey I have a similar problem on a Z5 premium it downloads over the WiFi takes hours then gets to 98% stops and starts the full down load again and I can't get Sony Companian to update it for me either
