Samsung Galaxy Pop got stuck while updating to Jelly Bean My Samsung Galaxy Pop (GT-S5570) got stuck while updating to Jelly Bean with Cyanogenmod 10.1. It sticks at the Samsung logo at the start. What can I do to get it working again?
I would go to the forum section of your device with whatever site you use and find the links for Odin and Samsung's official Kit Kat release for your device and flash that using Odin. Then you will be stock once again then accept the update and all should be fine.
