BetterPowerDown cydia tweak brings classic iOS 6 style power sliders.
Furthermore, if you are a current RePower user, you can enable the RePower functionality built into BetterPowerDown and have respring/reboot sliders that are also styled to either 7.1’s or 6.x’s!
No Partialzipping required! The iOS 7.1 images have been redrawn from scratch to ensure they’re high quality, and the iOS 6.x images already present on the filesystem are used to ensure an accurate iOS 6 experience.
Configure options from Settings app.
