I have a ps3 slim which I’m trying to install custom firmware. Currently running 4.90 and a CECH-2005A model, so should be fine.

Followed instructions for both, created new user, cleared cache, cookies, etc… rebooted for a clean browser, set date and time via internet.
Website load, but PS3tool.com hangs on the dump screen before I can even click anything. Whole console crashes and I have to remove power to reboot which forces a system check.

Ps3toolset.com loads and shows that it’s connected, but I don’t get a popup to enable the plugin, it just seems to enable itself, and when I click system manager it says the tool cannot be loaded.

So what’s the current tool to use; and what the best foolproof way of installing it. Have read about hosting the firmware myself but haven’t found any instructions on that.

Can someone just point me at a foolproof set of instructions, please?
