It's hard to know what happened. But, do note that we STRONGLY advise people to use the supplied power supply and do not warranty units that are used with other supplies.
In particular, weak supplies can cause problem during upgrades, just when reliability is most important.
I would suggest that you repeat the operation with the Eventide power supply. You can usually get rid of the corruption that causes the "No algs" message by performing an "update purchases" operation on H9 Control.
