Special Instructions to Users on Custom ROM Firmware:
- It’s not just important to root the device but also you need to ensure that you have disabled the Lag fixes if any installed from the recovery mode. You also need to ensure that the Dalvik Cache in your phone too is wiped off so as to ensure that just in case if any data cache is there that too is wiped off completely.
