[Sostanco]

Hello, i have a fat ps3 40gb model with sem-001 board, when i try to turn on it take green led for about 30-40 sec then it self shutdown with yellow led! i have alredy try to remove battery and swap with another hdd, replace the power unit but it do always the same. The bluray drive work since i put a disc inside and it boot up, and sure shutdown after 30 sec

The usb port do not work and i'm not able to enter recovery mode. I use progskeet to read the nand and i found the last 2 update, 4.20 and 4.31. Any suggestion? Thx
