Liteon flash help

please can anyone help. i have a 24102b and its been fine till i flashed firmware to 5s5a. It still works ok, but dosent seem as good at copying games. i want to flash to an older f/w but the liteon flash util wont let you do this. Has anyone got any idea, i want to go back to version 5s54, is this a good version?. Ive read about flash utils like pflash, Can anyone tell me what flash util to use, which f/w is best for this writer, and details of how to use the flash util.Please on;y give advice if your experienced at doing this as i want to get it right, you can email me direct
