    i have succfully did the wipe data/factory reset &
    Wipe Cache partition but i am not able to find the ADVANCE option to Wipe Dalvik Cache
    kindly help me

    1. Install 3C Toolbox (Android Tuner) from Google Play.

      Go to Apps Manager > Manage > Turn on the appropriate boxes, do not turn on “fix permissions” Or “Update System Apps”, there are 10 boxes to turn on for what your trying to do.

      Turn on ” Notification” bottom right to show a synopsis of what was performed in your notification bar afterward.

      Hit “Okay”

      The device cache, dalvik, trim, etc.will be cleaned and databases optimized. Upon reboot your Apps will be recompiled and Dalvik will be rebuilt. You will see it go through one app at a time, it takes 2-3 minutes dependent on the number of System and User Apps on your device.

      You may also schedule this to be done, i.e. daily, weekly, etc.

      I use Android Tuner on a daily basis. Its a great app, with great developer support. Spend the couple dollars AFTER you use it and decide it’s for you. After SuperUserSU, and BusyBox, (sterickson) it’s the first App I install after updating, or flashing a new ROM.
