    Downgrade it's possible? (TV 4xx0 serie)

    Hi, I have a 42PLF4307/H TV and since upgraded to FW 0.87.0 I have an issue with 1080i and 3d activated.

    I like to know if it's possible to downgrade FW to 0.74.0 (because there was no problem with this FW).

    I can't try because I have no more FW 0.74.0 file, but I suspect TV don't permits downgrade.

    Many thanks for reply.

    Hi,

    unfortunately, the same problem with 88.0 , but I can't downgrade without 74.0 file (it was the original FW already present in my TV so I have never downloaded the file)
