Main board processor identification

Hello all!!

I am having issues identifying the processor type and micro sd letter on my Creality 4.2.7 board. It looks like something(isopropyl alcohol?) spilled on the chip and dissolved most of the writing on the chip. The top half of the chip has no writing so I can’t just read the type off the chip :cry: I’m looking to flash the firmware and can’t proceed without this info. Any assistance would be appreciated.

Thanks all,
James

You should be able to simply search based on 4.2.7 and your printer model and whether it has a BLtouch or not. Some more information on that might help someone to locate the firmware.
