46es7000 firmware downgrade.

[bilaltokay]

Hi,

I own a Samsung 46ES7000 model TV. I had previously rooted it using SamyGo and was able to use auxiliary applications like Oscam without any issues. About four months ago, the motherboard failed, so I purchased a second-hand replacement. The TV is currently functioning normally, but I haven't been able to perform the SamyGo root process; the SamyGo installation widgets do not appear in Smart Hub. I attempted to downgrade the firmware, but the "alternate firmware" option appears disabled, and the online downgrade process fails to detect the update from the USB drive. I haven't been able to perform the downgrade either. Even after resetting the EEPROM on the motherboard, I still couldn't root the device. I’ve searched the forums extensively but haven't found a solution.

Is there any other method available for rooting the device or downgrading the firmware?

Thanks.
