Unless you have included only part of the message by Chuwi then it does not state anything about the condition of the device when you return it. They only request for all components and this is usually the norm for RMAs.
After we found an older, less powerful processor than advertised in the Chuwi CoreBook X and CoreBook Plus, Chuwi has finally officially commented on this scandal - and offered customers a possible solution. However, Chuwi is still not commenting on the extent of this possible fraud attempt.
