My Nexus 7 32gb WiFi, running stock 4.2.1, is stuck on the Nexus 'X' symbol loading screen after boot. It stays there until the battery goes flat. The issue is that I have not enabled developer or debugging mode, meaning that I cannot connect to the PC via the adb.

Is there another way that I can flash a new ROM? Apologies if this is a question answered elsewhere, but all recovery methods that I have discovered so far require 'USB Debugging', which I currently do not have access to.

You don't need usb debugging to flash. You need to unlock the bootloader and boot in to the recovery. – Ryan Conrad Jan 30 '13 at 4:22
But how does one unlock the bootloader without having USB debugging enabled? – BiGXERO Jan 30 '13 at 8:37

All you need to is boot to the bootloader by holding the Power button and Vol Down at the same time for a while. – Liam W Jan 30 '13 at 17:40
