Your device's components are rated to withstand ca 10,000 flashes. Someone want to help us out with the math? It takes about 15 minutes to flash and setup
Flash * 10,000 = 150,000 minutes = 2,500 hours = 104.16 Days of continual flashing to burn out your device
If you flashed your phone on average 3x's per day it would take you...
10,000 div 3 = 3,333.33 days = 476.19 weeks = 9.15 years of continual flashing to burn out your device
My recommendation: FLASH AWAY!!! Who keeps the same phone that long anyway?
I buy one at least every year, and every other year it is discounted!
