this works. I have verified.
It seems that you can skip a step or two. The key is that you drop back to 4.1 official and let the error 1015 occur. From there, you can redsn0w up to your desired firmware.
If you get 160x errors, use iReb or Tiny Umbrella to fix boot loop, and your golden.
My problem is that I need to boot untethered to use unlock for my carrier. Redsn0w does not work for this and sn0wbreeze cant get around this DFU loop problem. So, I am still stuck trying to get 4.3.3 on my 3GS with to a 6.15 BB with no fix. |
