Restoring 6.1.2 to 6.1.2 ?

Hello, i'm trying to restoring to 6.1.2 on iPhone 5, i am already on 6.1.2 right now, but tweaks made my phone to enter bootloop.
Sadly my power button broke up too. I've been tried countless ways including trying to make DFU Mode ipsw installing.
I think DFU is only solution, but itunes doesn't even let me install it with its 21 error.
Is there any more solutions to make it or am i gonna lose my jailbreak and update to 6.1.4 ? What if i will uptade my mobile substrate via ifunbox?
Ah btw, i got my shshs saved for older versions but i am not sure things working in this way for i5

 

Looks like i am not able to delete the thread but problem is solved here

 

Ah now! Of course here's my solution!
1) I installed openssh via ifunbox, than ilexrat.
2) Than opened sshterminal via ifunbox and cleared all tweaks
3) installed mobilesubstrate, cydia, prefencesloader and mobile terminal again via ifunbox
4) tried to restart but it was still bootlooping
5) than used evasi0n jailbreak
6) than it started to boot flawlessly. 2 days and still everything is working perfectly.
7) its kind of selfie way to solve it, i don't know if this sounds possible or not to you but it works anyway

----------

thank you btw, my solution isnt restore based, but it works anyway
