My LT18i won't start! The notification lamp just keeps blinking red.

I also removed the back cover. Those two white spots have turned red... What do I do?

It is fully charged...

When I try turning it on, it just does a single vibration, then nothing happens.

Hi, any good if removing battery? When did this happen?

[#3]

Happened Wednesday... No luck with the battery, no. When I plug it in to windows, it says "Device not recognised" :S

Try to repair software with Update Service. Here's the download link, http://www.sonymobile.com/gb/tools/update-service/. Download and install to PC/Laptop, launch it and follow on-screen instructions.

Keep us updated.

As said, the computer reacts not. I have browsed the threads to find your solution, but PC manager can't find the phone.

Have you tried Update Service? The one I have suggested in the earlier post.

Trying right now, will keep you informed.

Ok, fingers crossed!

Yep. Still working on it

Dammit! The phone apparently disconnected mid-reboot, and now I can't make it do it again!
