No, tablet computers store their data in Flash memory a type of electrically writable read only memory (a solid state replacement for harddisks with no moving parts to break). Flash requires no power to retain data, once that data has been written.
I have no idea.
To erase your Hudl tablet, go to the "Settings" app and scroll down to "Backup & reset." Select "Factory data reset" and then confirm by tapping "Reset tablet." This process will erase all data on the device, returning it to its original settings. Make sure to back up any important data before proceeding.
Go to Settings > Device Info > Erase & Deregister Device
yes it will
No.
With a scan tool or by unhooking the battery.
Do you mean HOW TO ERASE or did they erase by themselves and you want to know why?
diconnect the battery then connect it
No. Replacing the battery will not wipe the phone. Make sure the phone is off before you disconnect the battery though!
Nope
Should be able to just disconnect your battery for a few minutes and it will erase the codes.
