Latest modem.bin LTE dongle firmware for Huawei B593u-12

Latest modem.bin firmwares currently available are T-Mobile customized 11.533.03.03.748 (2013-09-30) from SP105 and generic 11.433.61.00.00 (2012-12-04) from Polkomtel SP103. While these are customized for EM920u according to few forum posts I've found they work equally with Huawei USB LTE dongles such as E392 part of same MDM9200 family.

What's inside Huawei B593u-12 LTE router?

There ain't many pictures showing innards of B593u around and even less ones with any details. This obviously needs to be fixed.

Well, that was easy

I think ethernet switch and wireless aren't supported by opensource drivers so even with OpenWrt booting on Huawei B593u-12 it's not much use. USB connected LTE module is not detected, my guess is that some GPIO needs to be toggled to enable it. PCA9555 GPIO expander would need some work too. Also 256MB NAND-flash is missing, only 16MB SPI flash is found.
