Okay, it's unanswered.

Took the board to a specialist, they replaced NAND with same type/capactiy NAND from an iCloud locked board, still the same. When i plug the usb-c charger it switches from 5V to 20v and then reboots in a loop instantly. PPBUS_AON is switching between 12.06V-12.36V (even with disconnected battery). Tried to restore (via iTunes and Apple Configurator 2 too), error 4042.

A bad battery can cause this behaviour? I noticed that it has 12.06V and cannot charge it.

Or what should i check next?

Thank you.
