Can't "downgrade" from PIX Firewall 6.3.4 to 6.3.3-133

[timothywilson]

Using TFTP we cannot seem to get the PIX firewall 6.3.4 to downgrade to 6.3.3-133 version. We get an "unspecified error". We have TFTP installed on the laptop connected to the PIX via console and CAT-5 cable. We can ping the FW and have set the pathing configuration in the PIX: tftp <ip> c:\temp\pix633-133.bin. Is it not possible to downgrade? If not, how can we wipe the current OS off completely and start new with 6.3.3?

Problem solved. Note to self: In TFTP set the View-> Options-> Root Directory to the location where the .bin image file is.....
