XDA Flame not work

[tox72]

Hi, I purchaseed an XDA flame on www.hi-mobile.net, on july. The display of this device not worked so their replaced it with new device. Yesterday I received it. I extract it from its box, I put sim card inside, I put battery inside and I connected it to AC power. Immediately the led become blink orange. I leave it to charge for 4 hour, then I remove it from AC power, I press on/off button but it not work, the screen remain black. I reconnect to AC power and led become orange, I press on/off button and it turned on but now the led turned off. After installation procedure, I see battery icon was with pressure point. I see in the panel where is write: "Main battery: Unknow" "Battery power remaning: Unknow". The I try to turn on the phone. In the wirless manager I tap on phone icon, but nothing happen. I try to tap on Phone menu and it write on screen "The wireless radio is not present". I see in the device information panel "GSM Version: P5C2", "IMEI: 353095010051772".
I'm disappointed of this device, and I want someone help me to solve this problem. Is not possible that I buy 2 device and 2 device not work!
What do I do??
Thanks, please answer as soon as possible.
