Skywolfeye T199 Rotating 360º LED Flashlight COB Work Light

Hello everybody,
I ordered this flashlight (Skywolfeye T199 Rotating 360º LED Flashlight COB Work Light) from Aliexpress and doesn’t work upon arrival.
I checked inside if some connection is wrong but everything seem to be ok except the MCU chip that doesn’t respond to input switches.
It has 3 MOSFET transistors HM2302A to drive T6, COB white and COB red. These transistors seem to work but the chip doesn’t activate them.
I want to make it working and I’m thinking if this MCU can be replaced (has no references nor marks…)

I found some drivers with 3* AMC7135 or 2* AMC7135, maybe suitable for the T6, but how to connect it if the switch is not in tail, just a momentary little switch acting in MCU?

Thanks for any help
