Very likely one NAND chip is shorted to ground.
You can try injecting 1V and see what gets hot there.

3 SSD Nands are getting warm/hot, and there was scorch marks on U9080.
PP2V5_NAND_SSD0 is 1.5Ohms, removing U9080 and U9000 has made no difference to this resistance.
After injecting 1V without the two SSD controllers present nothing gets hot
So would it be accurate to say at this stage one or more of the SSD NANDs have internal short? Or the only way is to take U9080 U9000 from working board and test?

If still short to ground at L9080/81 after removing U9080, at least one NAND is bad.
