Stucking at the Boot Loop: Wipe Your Data & Cache

If your Android phone stuck at the boot loop and can't boot into the home screen after flashed a new ROM, it's probably you forget to wipe the data and cache which might cause such error. Your phone tries to get into the home screen but actually the leftover data or cache stopped it, so it will reboot over and over again. So wiping the data and cache in the recovery mode could probably solve your problem. To wipe the data and cache:

1. Shut off your Android phone and boot into recovery mode. Normally you could press the Volume Down and Power to do that, but it's different for every phone, try to Google how to do it with your specific phone.
2. If you are using ClockworkMod Recovery, navigate the menu with the volume button and select it with the Power button. Scroll down to Advanced, and choose "Wipe Dalvik Cache", and then go back to the main screen and choose "Wipe Cache Partition" after that. Lastly, head to "Wipe Data/Factory Reset". Please note that all of your apps and settings would be deleted.
3. Reboot your Android phone.
