Pearl Expert upgrade to v8 without recovery usb

[chien0721]

I’m about to upgrade the pearl Expert console from v6.1 to Titan v8 or v9. However, when we had our console repaired last year, the Taiwan dealer lost our recovery usb. I heard my colleague that their console couldn’t work ideally after upgrading and neither could she downgrade the system. Since he console is venue’s property, I have to assure it can work well no matter what version is. Any suggestion for a backup plan? Thanks.

you create your own USB, the oldest available is v8.

You may want to upgrade the RAM of the console and make sure all the ECN's have been performed
