Deutsche Telekom Speedstick LTE V is available in the following revisions:
The revision can be found on the bottom of the stick close to the sim card slot.

Since Deutsche Telekom announced Dualstack (IPV4V6 PDP) support end of August 2015 you may assume their currently sold LTE dongles support it out of the box?

WRONG! Its 2016 and this &?%!"$ device still misses it.

Manufacturer claims IPv6 support for E3372 dongles.

IPv6 Single and Dualstack PDP supported firmware

MegaFon Firmware (

Besides that this firmware is not primarily targeted for the european or at least german market its compatible and works quiet well (no crashes, freezes). The used frequency band plan aswell as the cipher/auth sets match the ones we use.

I successfully flashed this firmware on a Huawai E3372h-153 on Linux.

Windows Updater

You could run Huawei's native updater to install the firmware. In order to proceed a firmware pin calculated from the IMEI is required (see LTE-ForumAT). However, in some cases upgrading still stops and fails with error code 16 or 19. (Pin hack is not required for this)

Balong Flash

In idle operation the dongle blinks green every few seconds.

Open your dongle carefully (two torx screws right to the usb connector) and release the clips on the two long sides of the case. Short USB ground and the left pin (see img0004.jpg), plugin the USB port and keep it shorted for about 5 seconds. The dongle should not blink and virtual serial interface should be listed in dmesg. (Double check the device names below). Next step is to flash the loader.


$ ./balong_usbdload -p /dev/ttyUSB0 usblsafe-3372hv2.bin

Once the provided code is booted the dongle led will start flashing in white. This may take up to two minutes and afterwards flash the firmware.


$ ./balong_flash -p /dev/ttyUSB2 -g0 E3372h-153_Update_21.

The dongle will now restart and boot the new firmware code:

Manufacturer: Huawei
Model: MegaFon M150-2


From this point your dongle should be IPv6 capable:

Connect the wireless network

I used QMI/NDIS and IPV4V6 PDP to get the Dualstack up.
PPP emulation with the virtual serial device rejected IPV6CP during negotiation. Looks like its not supported by the device at all.
