    My OP2 is retiring. it is still in good shape and can be traded for some extra money. My concern is how to delete all data on the phone. It seems factory reset not enough. What is your thought on this?

    Try wiping the data from recovery if it still doesn't work then use kill disk. It should delete everything beyond recovery.

    Go to recovery- select advance option and click on format data. This will clear everything in your phone.. let me know if you have any questions.

    Select rest all data in settings and once selected you have an option to erase internal storage along with the system data. That should theoretically delete all data on the phone.

    What does it mean 'kill disk'? Thanks
    You mean boot into recovery mode?

    No, this is not secure enough. I read a post on CENT and that is why i am asking in here for a better solution.

    P.S I found out an solution that can permanently delete all data on Android:

    If you really want your data off of the phone burn it... True story :) HOWEVER, in theory, if you wipe the data completely, and I mean even the system partition, when you reflash the ROM and setup the phone with another account all the pointer nodes in flash memory will start relocating.

    i would:

    1) factory reset
    2) fill-in memory with random data ( with a terminal application and dd command ) (there are applications like "fill device" that should do the same

    Repeat these steps few times.. (if you are paranoid 10 times)

    switch off your phone
    press the volume up+power+home simultaneously.
    a screen will appear. using volume buttons, scroll and find recover move. select it using power button.
    on the screen that comes next, select English.
    then use volume buttons to scroll down and select factory reset. press per button.
    confirm again by scrolling down to yes and pressing power button.

    Ok so if you are really paranoid about your not-really-deleted data you can do this:

    1. Wipe all the memory, including user data, app data, caches, system partition etc.
    2. Re-flash the ROM and login with an account that doesn't have anything important to you, maybe create a new gmail.
    3. Keep using the phone for some time until you sell it, then wipe and re-flash again.

    This should overwrite most if not all the previous precious data of yours.

    Reply here what happened! You are welcome.

    If you so concerned about your precious hidden data post formatting then don't sell it
