Juniper SRX210 root password

I have been trying to access two Juniper SRX 210 at separate locations. The passwords documented are incorrect, and previous admin says he can’t remember what else they might be. I've tried everything except interrupting start up and disabling the watchdog check.

I know the some Junipers will reset to factory defaults, but so far it appears the SRX 210 will only reset the root password. I tried it on an old SRX 100, and it only changed the password.

Do you happen to know if the recovery function wipes the configuration as well as allowing the password to be changed?

Or does it just allow the root password to be changed while keeping the configuration intact?

if the below are already being tried out and of no effectiveness e.g. three ways to reset an SRX and J-Series device to its factory default configuration.
-Using the Reset Config Button (requires access to the front panel of the device)
- (likely not this since you not aware of login) Using the load factory-default Command (requires login to the CLI)
-Using the Root Password Recovery Process (requires console access to the device)

The a/m is more to describe the root password recovery method for Junos platforms. I understand also there is case of SRX Branch platforms and Junos 10.0R1, 10.0R2, and 10.1R1, a condition in which the password recovery process does not work. Hence after issuing recovery command, the system never reaches the point where the root password can be changed; instead, the system reboots. If that the case, below is the suggested as you stated to include disable watchdog...
