Pix 515 635 upgrade errors


So I have this pix 515 that was donated for use in a lab environment for testing, I already got my activation key for 6.35... but during the tftp upgrade in monitor mode i get <11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11><11>.<11>

on my tftp server it shows download percent of 0-300% and so forth. the pix then reboots and takes me to the spot to enter the activation key provided by cisco. I enter the key and get 2 checksum image failures and it reboots... that process will repeat and i cant do anything with it ???

I was wondering if RAM is the culprit. I dont want to buy ram for it if it could be something else causing the issue.

I have not got anything to help, just to state that I have the same problem. I have inherited a PIX following an aquisition and it will not boot. I get the 'Checksum verification on flash image failed' message.

I succesfully uploaded pix635 image, without seeing any of the output you have on your tftp server. When I reloaded I also got the same message annd the Enter Activation Key prompt.

I would like to try erasedisk.bin but I suspect faulty hardware.
