Hello
My ipatched switch seems to be bricked, i changed the emmc module and tried to flash it with donor nand, but i got confused in the process, so many errors along the way.
Please help.

As Hekate says, your emmc module might be broken or not all pins are correctly connecting.
In the worst case, the emmc module itself is broken but in most cases it's one of the datalines (other than DAT0) that is just not connected properly. As long as the CLK, CMD and power lines are working, the emmc interface switches to this so called low speed mode, using just 1 dataline.
Maybe one of the pins detached from the motherboard while removing the emmc board.
Just try to removing the emmc board and putting it back once more.

I think all pins are ok, it's another hardware problem because the switch doesn't charge

latest hekate will tell you that the emmc connection is not at full speed, this is similar to detecting faulty sdcard reader by hekate and it used to refuse to boot, the latest would simply inform you.

regardless if the emmc is for that console or not, it should init just fine, meaning it's probably your socket or the circuit that handles the emmc
