Same here with the IC, and now, a year after eMMC chip replacement, my MCU1 is acting up as well. I suspect they did not replace my eMMC with the upgraded chip.
Since I have only a month left on my CPO B to B warranty, went to VN service and asked to see the chip ID and status. They would not let me take a pic of the codes on their screen, and I did not write down the numbers like I should have. Info on a prior post here would have clarified the matter, but did not find it.
They said they cleared the memory, and I should reboot every day for a coup days, and the problem will go away. RRRRIGHT.
I had to install V11 before the visit, as they said they would update anyway, no matter my wishes to the contrary. Hope the chip can handle it
Will post the commentary on the invoice later, but I smell BS on the SC's part.
