I'm curious as to how you upgrade the E9 - I got one for use with a project I'm working on and I'd like to switch the Web UI to use English (currently Chinese) and to update the firmware. It's a tad flaky in that it'll run for a while and suddenly stop mining & stop responding to the web interface. My only recourse is to power it down, wait a few seconds & turn it back on again.

Sometimes it'll mine for a day, sometimes for an hour or so.

Thanks for any leads.
