I have recently bought a used HTC Evo 3D from the internet. The phone itself is in perfectly working condition and the software is in its original state; that means it's not rooted, it's not running any custom rom and it's not branded.
However, the previous owner seems to have installed many apps from the market, the launchers are kinda different and generally the phone is very 'customized and seems sloppy.'
My question is: How do I get the device to its original, fresh, stock state? I don't want to install a custom ROM, I want to have the original android provided by the device manufacturer.
I know the device has the "factory reset" option in the menus, however I don't know what it really does and how thorough it is.
Wiping the phone and installing the system from scratch would be the best option for me, however, I don't know whether it's possible.
What are my options here?
- I know what rooting is
- I know what custom ROMS are
- I can root the device if necessary, but I don't plan on doing so if not necessary
- Android 4.0 gets an official release for HTC Evo 3D soon - does this change anything related to what I need/want to do?
