shogun: once you have a CID53 phone it will stay CID53 for all eternity. JDflasher won't help because it's very very limited in what it can do. and i know because i have a CID53 k800i too. but i bought it like that. the best thing you can do is:

- not trying to mess with it
- wait for the new xs++ and hope that it will support CID53


kind regards
