tool 1 works only if the owner authority of the account with the lost key was changed within the last 30 days
the second one also doesn´t work, it allows to change the recovery account (if I would have the keys), but not to do an actual recovery (the field is greyed out):

Recovery is to recover an account who's keys have been changed. Aka Hacked/Attacked.

Recovery still requires having the original owner key before it got changed.

Ok, so if keys were lost, no way of recovery possible?

Recovery is only possible for 30 days after changing the owner key.
Owner key lost = account lost
