Orange Pi 4G IOT and Android 8

bitflame

I got my Orange Pi 4G IOT. It work, but have Android 6.0 as firmware.
I want flash Android 8, downloaded from Mega storage. But when I try to flash, I get an error that the partion tables are different and need make "Format All + Download".
In User manual it is written:
"It you select Format All, you will lose the calibration information which we worked before sending
out products. If this situation is inadvertent, please contact the Orange Pi service and obtain the
calibration parameters through the machine code, and re-flash the calibration parameters."

Can someone give instructions on what to do after making the "Format All + Download"?
