Chances of getting accepted are high, if the school has room and doesn't mind taking transfers and isn't overwhelmed with applications.
Chances of getting a scholarship are low, b/c most schools don't give scholarships to transfers. That's not to say they're aren't rare exceptions to this. If the school your "friend" wants to transfer to is a state school, he may be able to talk his way into an in-state tuition discount, for example. Scholarships for transfers are worth asking the school about but most schools will not give them because transfers do not help the schools' rankings - their LSAT / GPA numbers do not count for USNews - and most schools only give scholarships in order so that they can increase their rankings.
