Thanks for replying. I was using DRX 1.8 and sometimes I had problems with leds wakelock. I also think it's hard to believe my phone just bricked during the night, but it seems it's falty. On the day before I noticed something strange, the phone was hot without load. I rebooted and thought the problem was solved, then went to bed. I've charged the battery with my wall charger time enough to make it work if it was discharged, so far the phone doesn't turn on. Even connecting with USB cable without the battery makes nothing, no device connected.
My problem is exactly like in this video:
Just to alert, I saw today that Zopo released JB 4.1 for ZP900 on the forum zopomobile.
