Playstation 3 BRICK Black Screen, green led on and no HD or USB HELP !!

Hello, today I bought a PS3 with brick

without access to recovery and nothing but the green LED

Brick appeared Rogero 4.21, but not

made the patch and recorded the NOR and the problem continues as if nothing had done


removed after dump.bin with flowrebulder realized that the file is only 161kb bootloader_0, which would be common in 190kb 189kb

Can anyone help me with this problem?

thanks
