SamyGO

Might your tv ran out of free space if you transfered 2Gb file? COnnect via telnet and remove

I`m trying to understand what was initial cause of restarts. When last TV worked well and what did you (or didn`t you, but someone, or nobody) right before it started to reboot as you say.

If it starts software upgrade procedure with your given firmware, then means it accepts it. If it says no software upgrade found then means it does not accept it

Do you hear any noise coming from tv? Like "click" or so?

I'm not very sure about d5500, but as the rule, the most recent versions of firmwares of any series block SamyGO.

If everything works, the stay on your current firmware.

No DNS trick anymore.

To gain tv access PVR decoder uses netcat, wich can be recognized as potential risk by some antivirus software. No worries, nobody wants harm you

Nothing to be soldered. Just plug the connector. It must work out of the box according some experience. Just I'm not sure about certain model.

thats correct. And by reading all this stuff you will understand whether you need root or not

If your tv accepts 0000 firmware, then it should downgrade. If not, then means you are to late.
