Downgrade - is it safe? - komame - 12-19-2017 06:37 PM Hi, Is it safe to downgrade the firmware to very old version (v8151)? I want to perform performance tests of HPPPL code execution with old firmware and take measurements. RE: Downgrade - is it safe? - Tim Wessman - 12-20-2017 01:44 AM Yes, it is. Just be aware that you can't move data files backwards in general so they may be lost. Upgrading on the Mac does require being up to a certain level of firmware as well, so if that is your main platform be aware you'll need a windows machine. RE: Downgrade - is it safe? - komame - 12-20-2017 11:34 AM OK, I will do hard reset before downgrade and use windows machine. Thank you, Tim. |
