There's no need for a USB mod. The firmware is written to the SD card when in emuNAND. I tried 7.2 as well (I have a USB mod, but did not need it). I reverted back to 7.1 with emuNAND tool. No e-shop either way, but at least system settings work on 7.1. Not to mention you do not need to update to play online.Just wait for someone with usb mod so they can restore their nand if anything happens xD
ED: inb4 nintendo applies a sneak update that updates the fpga of the gateway and bricks it or makes it so the launcher doesn't recognize it as a gateway LOL
