if you had a BEGIN TRANSACTION before the update:
ROLLBACK

otherwise, you will have to RESTORE the database with a FULL backup of before that, and in case your db is in full recovery mode, you have to do a t-log backup (before the restore, of course), and you can restore to the point in time before that errror.

as I said, you will need a full backup BEFORE the problem...

you might want to check out to stop any activity on the db, and try out third-party tools to read the t-log, to get the updates to undo the work: lumigent logexplorer is one of those tools.
