Question in the title. The scenario is: owning both CFW enabled 3DS consoles (same model, same region... For example 3DS XL). One is second hand regular edition and beaten up but has beautiful serial number. For example FW123456789. The other is limited edition (Pokemon, Zelda, Monster Hunters...) ( may have an IPS panel or quiet hinge as bonus...) with random ugly serial number. Serial sticker swapping is done, but can't do a motherboard swap and afraid the repair shop would put a scratch on supposedly perfect 3ds console. So need to fix Decrypt9, 3DSIdent... display the ugly serial number! 3DS scene has gone so far so now new I think it's time to fancy some unnecessary stuff.
