ultrasn0w 1.2.8 and problems with decoding iPhones
This week the untethered jailbreak solution called evasi0n was officially launched, and with it has come a long awaited update to ultrasn0w, version 1.2.8 is now available on Cydia. Although many owners of iPhone 3GS and iPhone 4 terminals expected to decode their terminals with an old baseband, ultrasn0w 1.2.8 unfortunately does not do this properly for everyone. More specifically, ultrasn0w 1.2.8 does not decode most iPhones, although they are having an old baseband and the problem seems to be from the new iOS released by Apple.
Those from Dev Team have updated without much pomp their program, though normally officially announced this, and it gave me something to thought. Seeing that users can not decode devices, it was clear that somewhere in the middle is a problem and unfortunately it affects many people. At present, those who had tethered jailbreak on iOS 6.x and used ultrasn0w fixer with ultrasn0w, must completely uninstall ultrasn0w and fixer, to reset their terminals and then try to reinstall ultrasn0w to making it functional. Custom IPSW made by sn0wbreeze seems to be a source of problems for ultrasn0w, many of those who used this method to update to iOS 6.x have noticed that they cannot use ultrasn0w.
If after a new restore you cannot use ultrasn0w on iOS 6.x, then it is advisable to wait for any new updates. It was said since a few months ago that using old basebands for new versions of iOS is problematic, and now we see exactly what this means.
