3550A Crossflash, RELEASE PLZ!

Did you try changing it back again? The drive converter does NOT switch a 3550 to a 4550 drive, but only changes an internal ID.

Yes, nothing is help. I change it back, and flash different firmwares, but drive still broken, then it roll up it tray, nothing is happen later, only a sound, that it wants to speed up disk many times.
