I had a ipad mini 6.1.2 jailbroken and used smoothly. Until I installed the PDAnet from cydia.
After a reboot, my ipad boot up and shows the activation screen (which I of course had already activate my ipad). I have try every means to get it activate again but no luck. It said cannot connect with wifi, and shows error message 0xE0000065 from itune.

It did not totally reset my data as my existing wifi connection were still remembered.
As I have installed sbsetting, I try it on the status bar and it appears, sadly I didnt install openssh so connecting using ssh is a no go.

I have all my data backup but I dont want to lost the jailbreak capability. How can I save my 6.1.2, please?
