Clean Flash

Clean install any ROM - Properly:

1) Backup apps & or app data via Migrate/MyBackup Pro (i recommend, as do many, using Migrate or MyBackup Pro over Titanium Backup - Ti has a horrible history with myself and others of borking restores...MyBackup Pro has never let me down) - leave set backup location to internal (its faster and less prone to errors) and then copy the Migrate folder to external sd card (if using Migrate) OR copy rerware folder to external sd card if using MyBackup Pro
2) Backup Downloads/Pictures/Media etc - DCIM/Pictures/Music/Movies folders to PC
3) Reboot to recovery (TWRP)
4) Wipe > Advanced Wipe > Tick all except MicroSD Card, then swipe to wipe
5) Press Back until you see the option to Format Data
6) Format Data, then type "yes" and swipe to format data IMPORTANT: this WILL remove Downloads/Pictures/Media etc - DCIM/Pictures/Music/Movies folders, make sure you have a copy - Step 2
7) Press Back until you get to the main menu
8) Reboot > Recovery > swipe to reboot to recovery
9) Advanced > File Manager > external_sd > tap Android folder, tap blue folder in bottom right corner, tap delete, swipe to delete. Press back, locate LOST.DIR, tap blue folder in bottom right corner, tap delete, swipe to delete
10) Install > locate ROM file > swipe to flash
