This is from manual.The prossesor is Novatek NT72567 and downloading of profile is different

G. USB OPERATIONS
USB Operations is used for updating panel, audio, video, etc. configuration parameters on the main
software. Necessary files should be copied in the USB stick root directory not in a file. In addition, the tool
called mksquashfs needs to be copied in the root directory. Below files can be updated;
ptf.ptf
PQF.bin
PCF.pcf
preset_list.sdx
AQ.bin
bornova_hwprofile.bin
bornova_swprofile.bin
logo.bin
hdmiedid.bin
vgaedid.bin
PRODUCTION_CREDENTIALS.bin
hdcpkey.bin
After making ready USB stick contents, plug the stick in to TV and run Usb Operations in one of the two ways,
via service menu or running test tool command of "USBOPERATIONS"
The update will be finished within couple of seconds. If everything goes well, you will get following messages
in bold format at the uart output,
>>> Update RO success <<<
...
>>> Update ROFIX success <<<
