Hi this is my first post so if I'm repeating this post, I'm sorry. I have a 3Gs with 4.1 installed.. i managed to get shsh blobs for 6.1.2 but the activation ticket is not included in it.. only my 6.1.3, 4.1, 4.2.1 blobs have activation tickets. when i try to make a custom firmware using sn0wbreeze in ifaith mode it says my 6.1.2 blob doesn't have a valid activation ticket. But as dumb as it look i just edited the shsh blob and pasted the activation ticket of the 6.1.3 blob to 6.1.2 blob and ifaith accepted that blob and created the custom firmware. but when i update my 3Gs using that custom ipsw.. the updating completes and itunes says it has successfully completed.. but my phone doesn't reboot. it goes in to a soft DFU loop. how can i fix this please help me.. and yes i could always go to 4.1 though this doesn't work. i cant go for 6.1.3 as there is no untethered jailbreak for it ... i have blobs for 4.1, 4.2.1, 6.0.1, 6.1.2 and 6.1.3 out of them 6.0.1 and 6.1.2 doesn't have activation tickets.. all other blobs do Update - Its ok if i have to go to 6.1.3... but is there a untethered unlock for it! ill be glad if anyone can post me how to get it done!
