Hi, has anyone had any luck with the latest (about 3 weeks old now) ROM for the BV9800 Pro? I have tried numerous times to install it to no avail. Could anyone give me any pointers?

I have put a brand new sd card in. Formatted it as external storage. Downloaded the ROM to it using my computer as well as using the MEGA download app. In both cases it downloads fine. I then go to settings->system->advanced->about phone->wireless update and use the 3 dot menu on the top right hand to tell it to do a local update. It reboots, shows the spinning update, then fails.

When I checked the logs I see a bunch but the most pertinent seems to be the following:
