Unable to flash filesystem in WSL environment

[Merculous]

I'm trying to restore with an Ubuntu WSL environment and I've been able to get to restore mode during an erase restore however I get this during ASR.

Here's my idevicerestore version:

idevicerestore 1.0.0-223-g61a76ce (libirecovery 1.2.1-4-g2405a80, libtatsu 1.0.4-2-g1d31ade)

I'm restoring a 3GS with latest iOS flag aka 6.1.6 or 4.1.

I am using WSL USB Manager for USB passthrough.
