When you say updated the EFILive software, what version did you update to? Also, if you have a FlashScan V2 device did you also upgrade the firmware at the same time (required)?

As at time of this post the latest software versions are:
- 7.5.6 Build 133
- 8.1.2 Build 115
- 2.06.41 V2 firmware

Please see these guide for more detail on upgrading software and firmware:

- Firmware

Once you have these versions installed try a flash again.

Cheers,
