Not sure why these blocks aren't starting with "mmcblk", but this could be a problem.

Huawei P20Pro (Clt-L29) /sys/block looks the same and fails with the same error

Not sure why these blocks aren't starting with "mmcblk", but this could be a problem.

I believe this is very similar to the situation of #39. Do the sd* subdirectories contain individual partitions?

One reason that I've semi-abandoned this project is because it turns out that there are too many different partitioning approaches on Android devices, and without access to the devices themselves or some very detailed database of how they all handle it… I can't keep up.

If you are interested in writing and testing a PR that can allow tetherback to map partitions with a different naming convention, we can incorporate it.
