Hi there, apologies in advance if I'm mistaken, but unless I'm missing something here and this is a special case or something specific to this phone, you probably will need to back up before a factory reset, especially if carried out from within the phone settings menu rather than via recovery (in my experience at least, I've found the recovery reset will sometimes leave internal "sdcard" partitions alone whereas I'd found the reset via settings to zero the entire device, thus losing anything not backed up from internal "sdcard" type storage, such as photos, etc). But if you have nothing to lose from your internal storage, or everything is already backed up to the cloud, you should be right to go without backup. Apologies again if I've misunderstood the situation.

Cheers,
Mg.
