I have a locked iPhone 3GS. New BootRom: 359.3.2 Baseband: 05.11.07 (eligible BB for unlock) Current version: iOS 4.1 Platform: Lion 10.7.2 With Ultrasn0w 1.2.5, I would be able to unlock it on iOS 5.0.1. Before that, as we all know, I need to jailbreak it first on iOS 5.0.1. With Redsn0w 0.9.9b9d, I successfully created a custom IPSW (NO_BB_iPhone2,1_5.0.1_9A405_Restore.1.ipsw.) from original iPhone 3GS 5.0.1 IPSW. Went into Pwned DFU mode and tried to restore the custom IPSW with iTunes 10.5.1. Without TinyUmbrella (v5.10.01), iTunes refused to proceed with the restoration on the custom IPSW. With TinyUmbrella, TSS server on, able to bypass Apple (gs.apple.com). Proceeded one step further but failed on Error 11. (due to absence of BBFW file). Problem is, I need the BBFW file to be removed so that I can preserve my baseband for the unlock. Therefore I cannot put back the BBFW file to overcome Error 11. Now I am stuck. Can someone offer me some solutions to complete the jailbreak? I have read quite extensively to self-help. Is there something I am still missing? Thanks much.
