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.


Polkomtel one is generic as there's no operator ID in end of firmware version. Which means T-Mobile has requested some sort of LTE modem firmware customizations from Huawei. I haven't noticed any difference in functionality myself, but depending on your operator there might be some.

You can check version after opening SSH connection to router using "lteat" command.

Did you spot it? #27 is different. Not that I would much idea what that means or if it matters. Quick googliohakuplaza search says it doesn't matter as long as SIM card used works with modem firmware. So it's not like some frequency would be disabled or other nasties.

This forum post provides bit more information of these registers, but not much about #27 we're most interested.
