GLK240128-25 stopped responding after firmware update 8.4 to 8.6

Hello,
As mentionned in the subject, after I update the firmware version of the GLT240128-WB from FIRMWARE-8.4 to FIRMWARE-8.6, it stopped responding.
I am currently using a microcontroller to send data via serial RS232 protocol at 19200baud.
PCB Rev. seems to be "4.0".
I just wanted to know what changes were made beside the "Current Font" changes from 1byte to 2bytes.
I looked around on the website for product changes, didn't seem to affect my commands beside Current Font.
It seems I am only able to clear the screen, and not write any character on the screen at all, cant set brightness.
Tried with mogsharp 1.1.8, I am able to do everything with the software.
If you need additionnal informal, it may be provided.
Thank you in advance for the help,
Eddy.
Issue has been resolved many thanks to Daniel.
Turns out the issue was within the command "Current Font".
What i send to the GLT240128-WB was "0xFE 0x31 0x00 0x01"
But the correct sequence is "0xFE 0x31 0x01 0x00"
