Motorola i860

I recently installed Webjal to upload some files to my i860. After loading a picture, I tried to access it and my phone shut down. Now when I turn it on, it shows me "i860" on the white screen like it's supposed to do, then goes blank and the screen goes black 2 minutes later. No amount of button clicking makes any difference. I must remove the battery to get anything to happen, but it only repeats the same routine. Can anyone help me?
