SRX

We have a Juniper SRX320 that I was trying to upgrade to the latest Junos 24.4, but has given errors during that process.

It was functional running 20.2R3-S2.5 with a basic config to allow network connectivity and ssh access.

Following TSB92728, I first tried installing 23.4R2-S3.9 using "request system software add" with the "partition" option. This did not give any errors, but after reboot, it's unable to load any kernel, per this error:

I then tried to install the image from the loader prompt using tftp, per the Junos Installation/Upgrade guide. However, this yields the following error:

I confirmed that this is not a network communication problem between the SRX and the tftp server. I run a packet capture on the server and see bidirectional traffic between the two devices for maybe 20 seconds, then this "error 60" appears. My guess is that there's some problem with the internal media on the SRX that prevents it from downloading the whole update image.

Any ideas?

I think this is effectively what I'm doing, except rather than grabbing the file from a USB drive, I'm grabbing it from a tftp server. (This particular device is in a space where it would be difficult or impossible to use a USB drive.) I suspect what's happening is the device starts to receive the file, tries to write it to internal media (eUSB), then fails because the eUSB itself is bad. So I guess what I'm wondering is, is there a way from the bootloader prompt to verify if the eUSB is bad?
