tessi писал(а):downgrade the LG C9 is not possible
Besides downgrades being impossible, I have trouble upgrading my C9 from 04.71.05 to 04.71.15 or 04.71.25 with LgDTVUpDater.I successfully used this software+script package a few times in the past since 2017 (and an LG C7).But now I can't even figure out what could possibly be wrong (I receive no clear errors in the CMD windows and only vague warning-like messages with dual-server).I obviously tried both old and new methods, went through the manual interface IP settings several times, tried different computer (both with wired ethernet and WiFi on both the PC and on the TV as well) deleted the entire working folder and started from scratch after reading the translated instructions yet again, etc.This is the first time I am unable to get it working.The TV sees the DNS server (s) but finds no updates.It's an EU model, so I use the RU file as usual.
P.s.: Sorry for English but I couldn't resist after somebody else broke it.
