iPhone4 stuck with Apple logo after jailbreakme

[finalcut]

Hello,

As the title state, my iphone 4 is stuck with the apple logo

I've tried hit home+power for 10sec, the release the home while keeping the power for another 10 sec to enter in DFU. The phone then close. If I plug in my macbook pro, the apple logo gets back and stay there. If I powerup the phone without being plugged in the macbook pro, the result is the same.

what to do?

regards
