I'm using this guide to jailbreak http://iphoneblogr.com/2011/03/jail...-using-pwnage-tool-firmware-bundles-tutorial/ but at the last step, the guide says to enter cd desktop/tetheredboot ./tetheredboot iBSS kernel This DOES prompt me to enter DFU mode, but once my phone does and then the injection attempt starts, it fails. Here's what my terminal shows: ibusb:error [darwin_reset_device] ResetDevice: device not responding Exploit sent Reconnecting to device libusb:error [darwin_close] USBDeviceClose: no connection to an IOService Waiting 2 seconds for the device to pop up... Connection failed. Waiting 1 sec before retry. Can anyone PLEASE offer some help on how to fix this? My Cydia app is starting at me on my home screen, but when I open it, it instantly re-closes. Thanks so much.
