I had no choice due to circumstances but to upgrade to 5.1. The only way to JB was to have a tethered JB. Well now every time I need to reboot I constantly have the same issue. I shut the phone, connect the phone to my pc and it constantly cycles. It shows the spinning wheel, asks me to enter my password and without doing anything it cycles back to the wheel and then back to the password prompt. Have very few jb apps but sometimes there is a need to reboot. I only bought the phone to use jailbroken but this is very frustrating. Here I am again restoring to factory settings and then rejailbreaking. Am I doing something wrong when I attempt to jb? I tried downgrading with tb but had many problems even with the blobs saved.
