I have DRX 500ULX (recently bought from bestbuy). I guess it’s a latest model. I installed 2.0F firmware (maybe I didn’t read the sony instruction carefully, it appears that only older model 500A needs it)
- Should I have upgraded with firmware 2.0F ?
- Does it degrade the performance. Is there a way to safely uninstall it.
Thanks in advance for your advices
