I assume bekit 1105 AND 1126 were both attempted? The 1126 one has the switched partitions, which some of the newer devices have.I can't find the erase command but there is a format_all and that didn't work. However, when I ran the VerifyPartition switch I get:
ERROR: Partition with Id 0 does not exist.
ERROR: Verify partition arguments check failed: 0
This is what I suspected had happened. I think the update may have wiped it and crashed or something along those lines and that is why I don't see the logo boot screen.
