I install the bootloader and extract the iso file to external HDD or just burn it on DVD RW. The blue boot screen after the system startup is accessible and there is an icon of the controller and flash disc or DVD. But when I press the X button on either of the two, the system freezes. The symptoms are as following:
The screen does not change. DualShock cannot be connected again if disconnected (no luck with a keyboard, too).
If I use the DVD, it seems to start reading it just before dying. If I use external HDD, it gets disconnected (even the via-USB power supply).
The PS3 can only be turned off after holding the I/O button for about 5 seconds until the second beep. If I don't do this, the green LED would be flashing, but the system wouldn't shut down.
The eject button works fine in this state.
The PS3 is 40GB Japanese version.
Can anyone help, please?
I have tried downloading the bootloader and iso again from another source (all from this forum) with no improvement.
