hey u went to dump eid_root_key and my controller is not connecting back my ps3

Does it turn on at all? Try turning the PS3 on from the power button and then plug the controller charger and controller in. Also, try following this tutorial made by Kryptus to see how it is done.

I don't think you need a spoofer on DEX Firmwares.
