Hi, I have an Iphone 4s running 6.1.2, jailbroken. I was wondering if it is possible to update it to 7.1.2 NOT ios 8.x. I have tried downloading the appropriate ipsw and restoring through itunes but i constantly get errors 3004 and 3194. I have also tried running a restore using latest Redsnow however when I load up the 7.1.2 ipsw, its says its not supported. Any thing else I can try?
