Okay, I'm a noob and I don't know how to copy the files over to do the 1.51 SP1 update. Would someone be willing to do a complete step by step guide on how to copy the files over via SSH and then run the script? I imagine I am not/won't be the only one searching for a step by step tutorial on this.
Hans, Thank you so much for pulling this together!
However, I am concerned as I pulled down the ItusrestoreImage from dropbox and scanned with my ESAT NOD32 Antivirus it reports "C:\\ITUS Shield\Shield_FW_1.51\router.tar.gz » GZIP » router.tar » TAR » ./usr/lib/ettercap/ec_dos_attack.so - a variant of Linux/Flooder.Agent.AK trojan"
My thought was this was a false positive initially, but since downloading it ESAT has been reporting more folders unable to be scanned.
Just registered - thank you very much for this Hans!
Noticed that the curl command downloads the accessinnov captcha page rather than the upgrade script, so I had to manually use vi to create it. You may want to place this in a route that isn't protected by the captcha.
