I gotta ask, what is the purpose? Curious :)
I don't know if you'll be able to go back one version. I believe if you load the factory reset file (there's a tutorial from CaptainKangaroo on IPTVTalk.org), it will rollback all of the updates to the stock firmware but it will update to the latest version when you do update instead of loading each of them separately. Think of it this way, you might be able to rollback to v.1.0 but when you get the notification for a firmware upgrade, it will be to v.3.0 instead of v.2.0
just came across this thread and wanted to ask- it's not the tv service but when the firmware updated most of my apps wont work correctly with the dreamlink remote. anyone else have this issue and is there a fix?
I'm not sure about the dreamlink but.
Every device I have ever put custom firmware on has had the ability to rename or edit the header.
You should be able to find instructions.
