[Q] Noob Q' : Why wiping ?
I've been flashing ROMs for quite some time now, and although I understand very well the need to do a full wipe when going from one ROM to another, I don't quite get why it helps to do so when upgrading to a newer version of the same ROM.
For example, I'm about to flash ARHD 30.0 for my HTC One, coming from 21.0, and they say Full Wipe is mandatory. I'm an obedient boy and so I will full wipe. But how come it's mandatory ? In my ARHD example, those ROMs are based on official HTC versions and in that manner are very similar to the official OTAs, but when official OTAs are rolling out, basic users rarely have to do a factory reset. What is so different about flashing a ROM ?
I'm just curious
Thank you !
