How hard was it to downgrade from 5.40.01 to the one your on now?
I been dragging my feet on downgrading, as I', clueless on all that router talk in the instructions.
I believe 4.31.20 is the last "good" firmware. There was a 4.31.25, but I believe that was just for UK sets.
Once the 5 series came out the Game HDR mode was dimmed, system response slowed to a snail pace and then eventually the dreaded glow appeared.
Anyway, the process is kind of a pain to figure out. The instructions are clear, but it is still a bit confusing at times.
I was actually able to complete the process over WiFi. It says you have to hard wire, but turns out you don't have to. My guess is it is safer since the connection is more stable.
Word of warning you may brick your TV if things go wrong.
a few tips:
- be sure to work directly off the C: drive. Don't use an added subfolder or unzip to your desktop. Just copy and paste the unzipped files to the root drive and work from there.
- completely disable the windows firewall. I was having problems until I completed this step.
- editing some of the files to accept 5.40.01 was a pain since the text file was not easy to navigate in the notepad app. Have to put files size and dates in there which is a chore.
Once you successfully get 5.40.01 on there replace the previously edited update files with a fresh unzip of the github files. I recommend this step since the files are already pre-edited to accept the 4.31.20 firmware provided at the github link. Saves you some text editing work.
Can't believe we have to resort to this type of nonsense. Thanks LG!
