  2. PwnageTool fails to build the IPSW on:

    2010-06-21 19:44:25 – Converting root filesystem to UDRW image.
    2010-06-21 19:44:25 – FAIL
    2010-06-21 19:44:25 – Failed to build custom .ipsw file.

    Any ideas?

  3. Hi,

    I am on 3.0.1. old baseband with jailbreak by redsnow and unlock with ultrasnow.
    can I use ur custom firmware too or do i have to update to 3.1.3. first?

    Thanks for your help.


  4. @Frank: Du musst auf jeden Fall auf eine CFW 3.1.2! Und dass geht atm nur wenn du shsh’s dafür gesichert hast
