  2. Can I do this process in Mac OS X 10.3 Lion that was released in 2005? My PC is damn too old so I can use that version only on my VM

  3. Does anyone have a copy of s0meiyoshino they could post a link to? The one on Github no longer contains all the necessary files

  4. Hey guys! Anyone trying to downgarde an iPhone3,2 device it won’t work. I’ve tried on mine, and it said: unsupported device. It only support 3,1 I guess after all.

  5. Worked wonderfully. Thank you very much. Now just in case, how is it possible to undo this? Because there is this weird boot animation that looks like a terminal. I don‘t mind it, but I just want to know if this is permanent or not, even on 7.1.2.
