Insert a working emmc into switch, you can dump your prod.keys, however, if you don't have the original nand backup, you won't have the switch unique prodinfo, please check your sd card, atmosphere will backup your prodinfo for youI have an unpatched switch that has a bad Emmc.Whenever I press the power button of my switch, it shows blue screen.If I inject hekate payload into switch, hekate works, but sd card isn't detected.I have an extra Emcc chip from an another switch.I can't dump nand backup and prods.key from a bad Emcc due to sd card undetected issue. I removed sd card slot and tested it on an another switch.Sd card slot is working.Is that possible to dump nand backup from a bad Emcc without a proper Emcc dumper ? Sorry about my poor English as It is my second language !
