After that i went through this forum and downloded many fw and upgraded by following guide's steps of this sites.
Only one i.e., 9.1.50 displayed succsess but player is still givving white light.
According 'tadad1's n other post(s), i need a full firmware but i think i didn't find it. whenever i was upgrading it by
9.1.51 ver i'm getting firmware error.

Please help in recovering this player if it can be recovered.
Thanks in advance
