goosey , the problem with the version numbers are that the manufacturers do not practice proper versions control. As they find cheaper alternative hardware, they modify the firmware to suit the hardware. However, they do not update the version number. So there could be tens or hundreds of variants of v9.0.52 which are not the same.
What is happening now is that likely you have flashed a firmware that is not compatible. The log only tells you that the file has been flashed into the player, it does not tell you that it is compatible.
What i can suggest is to try all the v9.xx firmwares for your screen size here
