I have SIM unlocked my 5s and had to do a restore for it to apply. So I did a backup then restored from that backup.
The thing is, before that, I did a semi-restore because I didn't want to lose the jailbreak (which is stupid because I lost the tweaks anyway so...)
So yeah, now my phone is acting up, I cannot send MMS, iMessage doesnt work anymore and my 3G doesnt work: even though I have the lil 3G icon displayed, it says "no internet" -_-
I want to do a full restore in order to get a clean 7.1.1 system that I will jailbreak after.
I still have the 7.1.1 restore .ipsw on the computer.
Can I do that or will it force me to upgrade to iOS 9 at some point?
