More and more errors after jailbreak

The first problem is everytime I open my cydia app it comes You have to apt-get update and i have done it now like 1000 times and still the same...

The second problem... Ohh. Haha, It is about cydia everytime im unstalling a tweak. it taking ages untill i can get back to home screen and eveeeerytime it is crashing by the hidding apps that is popping out and some crash apps to, something IOS.... dont really remember.. but anyways, im using also sbsetting, can it crush it something or?

The third problem is, when im rebooiting the springboard, it also taking ages to me to reboot it and it is kinda annoying....

I also cant get it to restore because of i have many thing like contacts, privite messenger that i really need to keep and a backup will mess this up again.

So i really dont know what to do to fix everything.. it really love this phone because it has everything but i really dont like how everything is crashing so please help me

All tweaks i use!

Btw, sorry for my english

 

OH okey, i will remove it then, but can i still write about cydia then?

 

Oh okey well, do u know how to help me somehow:/?

 

And how can i take back all my photos to camera roll, all contacts, privite and importent messenges?

 

But then all my tweaks and saved files will still be saved in my phone and will ********* my phone again... This is crazy... i have delete almost all my tweaks and still..

 

But how can i save all my contacts atleast?

 

Is it safe to use Itools to save contacts and so on?

 

Thanks Ya'll, i just restored and it feels alot better now. 15x faster than before hehe

 

Yeah, i had like 2GB installed from cydia, now im only using like 500mb.. So it is big difference!
