I thought about this a little more and there is another possibility apart from flipped bit(s) on the flash: The RAM being broken. And now that this cpufreq issue came up again it makes me think: what happens if the device gets stuck in trying to calibrate DDR RAM at to low voltage for many hours or days? Can that break the RAM? Maybe we should have listened to MediaTek engineers who very clearly and repeatedly stated that they recommend running MT7622 only at full speed and only ever did QA in that way?
