Hi , I have an iphone 4 which had with JB, a while back started to go slower and to hang, so I decided to make a backup and then restore to factory settings through itunes , so automatically I updated to ios 6.1.3 . ( at the wrong time I got the idea of updating ) and by failing untethered JB , I 've been all this time with a tethered Jb " redsn0w_win_0.9.15b3 " but forced to choose ipsw " iPhone3, 1_6.0_10A403_Restore " each once just had to make a boot .
The case is that I have a nightmare since then, going slow, stumbling , gets very hot, it gets caught , apps fail, the battery super- fast without using the cell is discharged , even makes me unwanted connections that I ever has blown the monthly data connection at the phone company .
Now at last there is already untethered JB for ios 6.1.3 but then, when I try to do I get the cell appears to have a JB and done, so I do not roll over and this is what I need:
- Restore to factory data , to remove any traces of JB , toxic or virus apps ( go you know ), but without updating the ios, ie staying on ios 6.1.3 .
- I would not lose the contacts , calendar, call log, email and settings, etc. . I do not know if this can be done from the backup without crap put back on the phone.
- And finally make it untethered JB for ios 6.1.3 p0sixspwn - v1.0.7 -win with the hope that everything will be nice as before.
See if some expert can guide me a bit . Thank you.
