    Hi there, does his new jailbreak fix the 3.1.2 Iphone 3gs bootrom issue? Eg. I restart/switched off my phone and I had to re-run blackra1n every time i reboot my device.

    Thanks, hope I could get an answer soon.

  2. Hayqal says:

    Cheers, looking forward to the tool fix:) Thanks Reshadat.

    Is Non-MC in reference to the model number beginning with MC for the i-Phone 3GS? Mine is MB717LL. So to better understand, is mine going to be a non-tethered jailbreak (like Blackra1n) should I use Sn0wbreeze? Or is mine considered the new boot-rom and be a tethered jailbreak? I have the beta version of Sn0wbreeze but am hesitant to try it.

  8. VuLN says:

    Oh thanks, i appriciate that!

  9. Saeed says:

    If the phone is still unlocked @step 10…how on earth am I supposed to get to Cydia?

    • Reshadat says:

      Your phone is jailbroken at step 10. so you must have cydia at this step. Then install ultrasn0w from Cydia.

      • Saeed says:

        Well, it didn’t have Cydia the first time around. I then restarted the whole process from scratch but it stopped midway during restore citing error (2) or error (1604). I tried to work around 1604 using iREB but I can’t put my phone in DFU mode. So what do I do now, any ideas?
