Xperia Arc bricked by OTA

[#1]

Hello!

I just received an OTA to my O2.de Xperia arc. De download worked an update stared (it turned of my phone and I got the box with arrow and 4 dots). During the update my phone did automatically turn off (batteey wan't empty) and now it doesn't turn on anymore. What happened? Is there anything I can do? I tried removing battery, hoding the power button, connecting to PC companion but nothing works. Did the OTA brick my phoene? How can I restore it?

Cheers,

Juhani

So. Apparently OTAs mess up your phones if bootloaders are unlocked.... That is just stupid. I bought SE phone because I wanted to support their open approach to phones (ie. letting people to unlock boot loaders). I think it is all BS if the OTAs you push then brick phones that used the unlocking...

Well. If anyone else encounter the same stupid issues le the people at XDA sort you out at: http://forum.xda-developers.com/showthread.php?t=1126358

Hi there,

If you have unlocked the bootloader you should have been aware that you cannot update the phone OTA as it will brick your phone. The information is stated on the page here http://unlockbootloader.sonyericsson.com/.

There are solutions at XDA Developers as the page also says.

Note : If you have an unlocked bootloader you will not be able to perform the update just like this.  You will first need to relock your bootloader

Go to this link to download the relocking file

You will also need a program to flash the phone with this relocking file.

After relocking your bootloader using flashtool, use SE Update Service to re-install the original software.

Also when it says that your phone has the most recent software. Just overwrite it.
