I suspect this has to do with the way the new firmware is compiled (some compilation flags have changed since the previous version). I’ve reversed those flag changes and updated the reflash zip file:

it’s now named og_1.0.8.bin. Give it a try and see if it works. If not, please submit a support ticket so we can arrange to have it returned to us in order to check why the new firmware isn’t working for your particular unit.
