Homepod flashing volume keys repair

How to repair bricked Apple Homepod with flashing volume keys. from disassembly to NAND chip reballing all in one video.
from our experience faults like these occur due to the CPU not recognizing the software so we try to reball NAND and in some cases the fault clears but in other cases in which the NAND ic or the OS in the NAND is corrupted somehow, are non repairable for now. we are still working on a possible solution on this problem.
