Motorola Defy Mini :: Won't Boot - Red Moto Only

I restarted my phone yesterday, or rather tried to - but it will not boot - it gets as far as the shimmering red M symbol but no farther. The only way to shut down ore try again is to remove the battery. Have also tried with USB connected, and with sim card removed. Battery shows 90% charge when USB connected.

Have tried hardware reset but it never shows the menu.

This phone is only a couple of weeks old and Im severely disapointed, my first time back to Motorola after many years away. It seemed like a good phone, but this is a great inconvenience.
