Failed Cross-Flash...

Thank you for the write-up. I have started on my spanking new D857 but came a screeching halt along the way:

the LG FlashTool linked to is the KDZ-only version

attempts to flash using the LG FlashTool with the supplied DLL and v10d .TOT file will fail due to the incorrect partition (refer to below or attached log); tried with both "Board Download" and "Upgrade" to no avail

And now, my phone is stuck in "Firmware Update" mode... :crying:

Currently downloading the v10f KDZ file to attempt to use the (other) FlashTool with the "CFE" mode to try and do a complete re-partition and flash... Will update everyone later.
