I am just a curious guy and some kind of perfectionist. I am trying to understand what is the relationship between open telnets and riskless root access. Does the exploit rely on open telnet or it actually use them?

You need backdoor in case of brick :)
I do NOT support "latest fw" at ALL. If you have one you should block updates on router and wait for it to STOP being "latest":)
If you want me to help you please paste FULL log(s) to "spoiler"/"code" bbcodes or provide link(s) to pasted file(s) on http://ctrlv.it/ Otherwise "NO HELP"!!!
If you want root DISABLE internet access to your device!!!!
DO NOT EVER INSTALL FIRMWARE UPGRADE !!!!

I can understand that. But I can't understand why cannot it be protected with a password?

Because that's how this telnet works and send password in plain text (which is how telnet WITH password works) is just stupid ;)

But don't you think that sending the password in plain text is still more secure than root access without any password?

It will protect the TV from script kiddies at least.

I don't believe in "security trough obscurity" :) Sorry ;)

I really don't mind to start a holywar. Could you please just say is it possible to enable password protections for telnet daemons or not?

P.S. In my opinion it is not "security trough obscurity" as if I will use ssh instead of telnet, the password will never leave the TV. In case of "brick", I will be able to enter telnet console, recover, change password and continue to use ssh. Why do you think it's not secure?

Don't know, don't care :)

Because IMHO it's pointless ;) It will not be "secure" anyway ;)

What a qualified answer! :ugeek:

P.S. GOT IT! You mean that you added another backdoor for samygo team, right?
P.P.S. As far as I understood, different telnets are for different TV models. You just enabling them all hoping that at least one will work correctly. So why cannot I disable not working ones after I found the port without "job control not running" issue?

P.P.P.S. I have an issue after rooting. TV doesn't power off first time. Instead of that, after pressing the button it shuts down for 5-6 seconds and turns on again. If I press the power button again before samygo getting loaded, it powers off successfully.
