Hello
i have a ps3 and usb jailbreaker which is grey and it doesnt have any brand or other thing on it
i bought it from alibaba 2 months ago
it works perfectly with old games but i learned it needed to be updated
i find some updates files but dont know how to use them
i read process are different from model to model so i dont know which is my jailbreak model and couldnt find any good how to about it.

mine looks exactly like this without the brand on it.
Thanks alot
