Need help with jailbroken iPod touch 5th gen

[Crypt]

I have an iPod Touch 5th gen jailbroken on iOS 8.1.2 with PP jailbreak tool.

 

After changing something in the springtomize tweak and respringing, my screen just went black after sliding to unlock. It used to backlight but not anymore (might be wrong, it's hard to tell). I am able to activate Siri by holding the home button but she says no internet connection (my iPod was connected to WiFi so not sure why). If I hold the power and home button for a while I see the apple logo but once iOS boots it goes black

 

I have two tweaks installed that might conflict/glitch and do something like this. They are f.lux and Dim. Dim allows you to set brightness lower than you can through normal apple settings and I'm pretty sure you can set it to 0.

 

I'm not sure why this happened but I need a solution without restoring as it'll update my iPod to an un-jailbreakable firmware. 

 

I'm not able to see the library folder in iFunBox to delete these tweaks.

 

I NEED HELP??? Any way to control the iPod whether it's through a computer or the iPod screen?

You might be able to get into a console of some sorts, but even then I'm not sure you can fix it. Don't know a whole lot about jailbreaking, only device I've jailbroken was the iPod touch gen2 and even then I didn't go that far with tweaks as it already was slow as hell.

I could buy a lightning AV cable but they cost $60 in Australia And there's no cheap Chinese copies 

 

EDIT: Not sure if this would even work actually

can you put it into DFU mode? if so you can still restore it via itunes(bah ) and then you'll have to jailbreak it again(and then be carefull with conflicting tweaks)

a restore is probably you best option here unless you get lucky and it suddenly works.

I believe there is a program that allows you to load any recent version of iOS onto it if you get the iOS version file.
