I installed a new chip ordered from Amazon today, it fixed the issue ! OFW now boots fine from eMMC. What a relief !

Well the seller sent me firmware 2.65 to flash (I have 2.74) but I could not flash it, after I drag the file, the chip disconnects and reconnects to the PC… And now my eMMC is even more corrupt (purple screen when trying to boot OFW). User data partition was deleted for some reason so I did a NAND restore. OFW is now stuck at logo again. EmuNAND still works. Still really bad experience overall. I ordered another modchip from Amazon this time. Let’s see if it fixes the issue… Now I really wish I left my Switch alone from the beginning.
