I do not know for sure, T210 is aarch64 while T124 is last gen on
armv7 so there definitely will be some compatibility issues. Nothing
that should not be possible to resolve though. I  don't have access to
T210 devices and most likely will never have unless there will be a
device donation or very cheap one on used device market.
