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?
