This guide maybe useless but do-able

Assumption :

Switch A has an SX OS License, it doesnt matter if the console is healthy or not, we just need its eMMC module
Switch B is a healthy and working console

How it work

1. Backup the Switch A NAND to the micro sd card if possible, but if you got a bad or defective unit, then remove the eMMC module only along with its SX OS license.dat
2. Backup the Switch B NAND to the micro sd card, and remove the eMMC module
3. Install the Switch A eMMC module to Switch B, then restore the Switch B NAND into it
4. Copy or use SX OS license.dat from Switch A into Switch B
5. Use the latest SX OS version , e.g 2.7.1 beta, and boot the SX OS
6. Done

So each SX OS license is tied to a specific eMMC module (the eMMC chip), because each eMMC chip has a unique serial number

That's it..

Solder wires from the connection points from the motherboard directly to SD card reader, if your SD card adapter on your baord is missing pins.

i bought an entire new as card reader from ifixit, and had an uncle put it in for me as i’m not good with all of that. it ended up still not working so i planned to just buy another switch. are you saying that this will help me?

if you can solder wires then yes.

could we rewrite the emmc chip serial Number ?

I don't think so. Why would you do that?
