I have a rooted Galaxy S3 GT-i9300 with Android 4.3.
I've rooted it using this method: https://www.youtube.com/watch?v=3gYjoW22h7c Now, I would like to erase all the data, but don't loose the root access. Originally, I was going to go to Settings and press Factory Reset, as I used to do before I rooted the device. But then I read in androidcentral that that could "bootloop" (https://www.youtube.com/watch?v=OKXTD1-fqbc) my device.
In summary, how can I do to securely wipe all the data (the option called "Factory reset" in Settings) on my rooted S3?
