I'm new and tried to Downgrade my D6200 from FW 1028.
No success till now

DNS Trick doesn't work -> Error 601 and Error 606 on my 2nd TV ( C6800 )
Did anybody sucessfully Downgrade and has a step by step guide How To ?
Rooting as described on https://wiki.samygo.tv/index.php?title= ... cpu_models also doesn't work.
Kind regards,
Peter
