DS-2CD2155FWD-IS Brick

[jwp]

So I managed to brick my DS-2CD2155FWD-IS trying to revert back to the stock R6 5.4.5. The camera pulls the file from TFTP, but never proceeds with the upgrade. I realize this is due to protection from 5.5.x to 5.4.x. I upgraded the camera to 5.5.61 for reference, and I am trying to go back to 5.4.5.

I then tried the R6 fake firmware posted in another thread, but still the same result. It pulls the R6 fake firmware down via TFTP, but never proceeds with the ugprade. I am able to SSH into the camera after TFTP via 192.168.1.64 with the login "root/hiklinux", so I am able to get to a shell. From here I try "/bin/upgrade", and receive the error message below.

I even tried to revert back to the stock 5.4.5 firmware, and nothing.


[ERROR] [MIN]BURN digicap package error, can not upgrade!!!!

I am at a loss here. Thankfully I can get to a shell, so it's not a total brick. Any suggestions on what it could be?

From what I've seen - the 'downgrade block' would not trash the camera, but simply reject the older firmware, leaving the original in place.

That's the usual 'downgrade block' error.

What does SADP show, if anything, for the status?

Have you tried re-applying the 5.5.61 and if so, what was the result?

**edit**
I'm not sure a 2155FWD is an R6 camera - though I'm not familiar with that model. Isn't it a G1?

Bingo, I was using the R6 firmware.

Reverted to G1, and it's fine.

Thank you.
