To use Cure firmware (or original for that matter) the device MUST be capable of turning on. Likely you have a different problem due to a faulty hardware component anyway therefore any software remedy cannot help anyway, sorry.

Try removing the battery for a while, even overnight. Sometimes that will work to drain all residual current from the device and when reconnected to a power source it will liven up. If not, you will need an electronics technician to trace the fault but if it's the flash chip that's dead it won't be worth repair costs.
