Re: [How To] Essential jailbreak/unlock/ssh thread!
In DFU you can:
1) use iREB to set it up to flash a jailbroken IPSW that bypasses some bootloader stuff.
2) downgrade the firmware
3) actually use the power button to "force boot" the device by holding the power + home button which sometimes kicks it on.
4) put it in DFU and jailbreak the current firmware with redsn0w which again may bypass whatever the bootloader or firmware is running into,
probably more stuff I'm too busy to think up right now.
