iPod touch Problem with Ipod Touch 5G

Recently for around the past week i have had a problem with my ipod Touch 5g. To clarify and make it easier to understand here is what's happening.

1. The time on my ipod began to go out of sync this was the first problem

2. The wifi began to disconnect and reconnect. This started occurring one day after the time sync problem

3. The ipod screen will have a screen glitch ( the screen has black streaks come down and then turn off) and this will cause the ipod to reboot

Some additional information about the ipod:
32gb
Ios 7.0.6

Also it is jail broken using evasi0n7 on ios 7.0.6.

Now what i have tried doing is restoring and rejailbreaking, but i am unable to restore due to apple not signing 7.0.6 anymore. So so far i haven't done anything to the ipod since this problem has occurred. If anyone can help me with this problem/issue i would appreciate of highly. Also im triying to find a method that can allow me to stay on ios 7.0.6. But if no solution can be found then i will be willing to update to ios 7.1.1 if that is the only way to solve it. Thank for taking your time to read this.
