Won't boot after firmware upgrade, stuck on "SONY" screen. What do I do?

[beachtwig]

I'm using Sony Bridge for Mac. Tried updating to the new firmware. At the end of the updating process, I got the message: Update failed. Reason: UE communication failed (code 100, text: )).

I tried the repair function (Phone > Repair Xperia unit) in Sony Bridge, it seemed to go smooth but then failed at the end again with the same error message.

Phone is just a few weeks old. What can I do?

Do you happen to have access to a Windows based PC?

Ok, in this case please try running the update with this when you can get onto the PC:

Well i tried this.. it refuses to recognize the phone no matter what... just shows sony phone connected and when i follow the on screen instructions it keeps saying switch on ur phone and let it boot.. which is not happening given the state of my phone.

PS: THe sony service centre tried to bill me Rs 8.5k ( USD $ 160) to replace the motherboard when its clearly a software issue. I hope this issue can be taken up at ur end.

Meanwhile

what are the other options you propose.

[beachtwig]

It worked, the phone is up and running again. I find it a bit lame that I have to borrow someone's Windows PC to perform updates though.

In this case please try the other program I linked above, this will not require you to turn the phone on:
