Thread: Possible Guide/solution to hactivate without official sim card

    Default Possible Guide/solution to hactivate without official sim card
    I have a 3gs old bootrom on 4.0 stuck at emergency calls only screen. I have been trying a lot and have this idea:

    1. Use Umbrella to save shsh blobs on file for 4.0.
    2. Restore to 4.0.1 ipsw using iTunes
    3. Cook a 4.0 custom ipsw using Pwnage Tool with activation selected.
    4. Use TinyTSS for 4.0 shsh blobs. More info/guide here.
    5. Use iTunes to restore with the above custom ipsw.
    6. If it's successful, you will bypass emergency calls screen and you can launch safari and visit

    Will this work?

    No, it wont. A phone MUST be jailbroken in order to accept a custom fw. If you have shsh's for 3.1.2 you can downgrade to that and use blackra1n to hacktivate the phone.
