Can someone please tell me (or link to a tutorial) the best and safest way to undo/ remove the glitch hack and return to stock. I have a zephyr with unreliable boots and want to revert to stock, and sell the console for cheap. Currently it has dashlaunch and dashboard v14699, but when i dumped the nand, it was at v9xxx something. Do you recommend simply flashing back the original nand?? Thanks
