[Sony Xperia 1 II ROMs, Kernels, Recoveries, & Othe] spicard:
This is super interesting, really looking forward to it, but can't get the partitions to write.

Luckily, the failure did not effect the stock android, so its not bricked but no lineageos yet :(

This is the xq-at51 and I did unlock the bootloader. TWRP installed fine.

Here's what I did:

And here's the partition list I get:
