Erisin ES9000A Bootloop. Which MCU Version?

[FloSchel]

Hello everyone, I hope you understand me, my English is not so god und Google help me with translation.

I have a problem with my Android navigation system. Device designation: Erisin ES9000A.
Unfortunately, the device gets stuck with the Android logo when starting and then does not go any further. I can get into recovery mode and now wanted to reinstall the MCU. Unfortunately I don't know which version I need. I can not look in the settings because the system does not start.
Is there another way to find out the correct MCU version?

On the Mainboard is a designation:
Kd-hct-mb 2014/06/24 Rev-1.5
On the circuit board where the Rockchip is on it is a designation: MTC_RK3066_Revo. 3a 2014.03.27

It was very nice when you can help me.

If you can get into recovery, have you tried to factory reset? That should get you back to booting so you can get mcu and system details to better address your issue of updating.
