(adsbygoogle = window.adsbygoogle || []).push({}); Hey im new to hacking and I need to know if it's even possible to jailbreak with only a USB stick anymore?
And if so, how do I get awesome file manager and what firmware must I downgrade to in order to download it?

You cant downgrade with usb, you need e3 flasher or some other downgrade stick. And for file maneger u need to be on 3.55 and use CFW (Custom Firmware) on it.
