Hey guys, i have an iPhone 4 on baseband 1.59 with T-Mobile USA, i have 5.0.1 on it and have all my shsh blobs saved with tiny umbrella from 4.2.1 to 6.0. I made a custom ipsw with redsnow because i wanted to update to 5.1.1 and i stitched the blobs to the 5.1.1 custom ipws, put the phone on pwned dfu mode with redsnow and went on to update by clicking the shift+restor and choosing the no BB update custom ipsw with the blobs stitched to it, it started restoring and then like 2 to 3 mins into the restore if gave me an error and the phone went to recovery mode. So i put it on dfu mode again and went back to 5.0.1, now, what was the problem? why would it give me an error when it started restoring and go to recovery mode, and why it goes smoothly when i go back to 5.0.1? What can i do to update to 5.1.1 and preserve my baseband, and once again i have all my shsh blobs saved
