Update #1: Until @i0n1c has a chance to fix the i4 version, we’ve removed the i4 untether from redsn0w (making it a tethered-only JB for i4 right now).
Update #2: redsn0w rc14 includes the fixed i4 untether from @i0n1c. You can re-run redsn0w rc14 right over the tethered rc13b to transform the i4 JB into an untethered one.don't forget to thank!!.. thank you.
