I guess many of you like me faced this pop-up message when running the Seas0nPass executable file.
I’m writing this topic to save you some time and have a better understanding.
No matter what version of Seas0nPass you try to run (older versions that used to work on your computer in the past), the same error message will pop up: " Unable to retrieve firmware details. Please check your internet connection and firewall settings. ".
Lately (early Dec.2015) I faced this when I decided to prepare to JB my ATV2 (currently tethered boot JB for 5.2.1) with the new un-tethered JB for 5.3 (Seas0nPass 0.9.6).
You’d spend hours trying to disable your antivirus and firewall, kill processes and/or set security rules, reboot, try with admin rights… Yes it is sometimes needed to disable you AV and FW, but the problem may reside somewhere else.
It took me a while and some research in a lot of forums to find out that Seas0nPass needs internet access to access some resources and if I followed correctly the experts, there’s in particular one website it relies on and that website sometimes is down!! Therefore in this case it’s pointless trying to find a fix on the client side :-(.
Well, this being said, I have no idea why it is down (maintenance?) and when it will be up again.
I won’t complain or nag about it because the Firecore Team did (and still does) an excellent job to help the community hence it is about being patient a few days until it is fixed.
Edit: (find below the solution I’ve found for my case)
