Hello all, I have a good condition iPad Air (1st gen, exterior wise) however after I updated to iOS 11 previously, it was never able to complete the update. It always have a part where it would stop updating and producing error "-1" if I'm not mistaken. With the iOS 12, it was able to complete the update but when I try to activate it with iTunes or without this error message pops up.

What I do know is the SIM card slot isn't working anymore, and previous googling I recalled error "-1" is FW update to the GSM band data corrupted or some sort. Is there any ways I could by pass this? Jailbreak?
