Can you just try erase chip command ( 01 CE FF 04 00 00 00 FF ) after the chip reset and try the programming sequence?
Can you please clarify whether you are using CYBT-353027 EVAL (http://www.cypress.com/documentation/development-kitsboards/cybt-353027-eval-ez-bt-module-arduino-evaluation-board ) or a custom board?
If EVAL, please do recover the device (by pressing on recovery button and resetting the device) and try sending the commands.
If custom board, I suggest you to keep a recovery button and reset button for the CYBT-353027. Do recovery procedure and then try.
