I wish the OP luck, but seeing that brand new XPR7550e's sell for $450, & a flat rate repair is $350, that radio was worth $100. Did someone tie a rope around that radio, & attach the other end to a truck bumper & take it for a 10 mile ride. Even if the OP can bring it back to life, & it works properly, the cost of a new case can push the price well north of $500, much more than brand new.
