Brick recovery - Bosion PX6 RK3399 - Black screen, no lights, no buttons

Hello,
i have a "Bosion" px6 android 10 (really 9) headunit which was from aliexpress.
i had an issue with the "autokit" carplay app showing artifacts, and the solution from the seller was to downgrade.
i was originally on
OS VER: KC1E0129-P01-11.1.4.9.1 - BLINK161 - 20210118
MCU VER: STM32-20210109-11-BD6-56
The seller provided me with
os_update_KC1E0124-PA1-1.1.4.8.1_20200729_180609
mcu-202007071001KC6-1154.upd
The update steps provided by them was as follows:
First update OS then MCU
i updated (or downgraded) to the os update successfully, but was missing lots of apps, DSP, BT phone etc, i then installed the MCU update, around 10% in the unit went black and has been in that state since. i allowed 1 hour before switching ignition off and back on but headunit still black screen no response or lights.
Not sure what went wrong? Was the file they provided incorrect?
What can i do in this situation?
Ive attached an image of the headunit.
Ive tried all sorts of recovery options ive read on here and on YouTube with no luck so far - Hopefully someone else can help me.
Thank you very much
