Upgraded to firmware 2129 before knowing SamyGo
Posted: Mon Mar 16, 2015 8:55 pm
Hi, people!
I know this is totally newbie, but *sigh* that's what I am. I've been wandering around the forum for a couple days and, yes, I know I should not have upgraded the TV's firmware. The fact is I did it a couple weeks ago and I didn't know about SamyGO at the time.
Now, as I should expect, installing SamyGO is not working as expected. I mean, the installation process works flawlessly, including applying data.zip, but, after everything is done, I don't get FTP and TELNET ports opened. In fact, netcat returns this:
Before installing SamyGO, I only had port 6000 opened, so something changed, which - I think - is good.
So I'm posting here to know:
1. Is there anything I can do in order to force FTP/TELNET ports to be opened? Modifying SamyGO in some way, maybe?
2. In case #1 is not possible, is it possible for me to do a firmware downgrade?
Thanks a lot, guys! Awesome work!
