I 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 !
