Set Huawei E3372h from hilink to stick mode
Inhaltsverzeichnis
1 Problem
Problem: The Huawei LTE Modem E3372h is a dual mode modem and needs to be switched into the hilink mode.
This is particularly important when used with a Mikrotik RB951 Wifi router.
2 Fix1 recommendet by Mikrotik Support
The original mode was: AT^SETPORT="A1,A2;12,1,16,A1,A2" I set the modem to: AT^SETPORT="FF;12,1,16" usb power reset, and it started working as a PPP interface. ------ I found theese settings using AT^SETPORT, and AT^GETPORTNAME: AT^SETPORT="initial_mode;normal_mode" map: 1 - Mobile Data Modem (MDM) 5 - GPS interface 6 - control interface 12 - PC UI 10 - modem? 16 - NDIS A1 - Virtual cd A2 - TF card reader FF - Dummy (disable modeswitch when using this as the initial mode?)
3 Fix 2, found elsewhere
Since an easy mode switch only seems to work with devices in stick mode, and as I had a more recent device with a more recent firmware, I needed to take a more complicated way. But no, it is not complicated. See by yourself:
I followed the instructions given here:

3.1 Preparations
This guide assumes you have Linux and a compiler installed and you know how to use GIT. So:
git clone https://github.com/forth32/balongflash.git git clone https://github.com/forth32/balong-usbdload.git
Go into these directories and enter "make". If you have a decent GCC compiler , "make" will produce according binaries.
Take a browser and visit the page https://www.lteforum.at/mobilfunk/firmware-versionen-hi-non-hilink-e3372h-inkl-mod.2691/
Then download the file linked behind E3372h-153 21.180.01.00.00 general (a 7z archive), unpack it with
7z x Huawei_E3372h-153_21.180.01.00.00_Firmware_general_3Ginfo.ru.7z
It will give you a file called E3372h-153_UPDATE_21.180.01.00.00.BIN
3.2 Open the case
The stick can be opened using a TX5HF screwdriver. You just need to unscrew both screws near the USB plug.
Use a flat screwdriver to carefully remove the rest of the case.
3.3 Set the stick into an init mode
Use a crocodile clamp or something else and connect the plug's ground to the first of the round contact pads. This will shorten your stick and set it into a boot mode.
The Russian guy explains how to do that: https://www.youtube.com/watch?v=0RsFQH-lAQg&feature=youtu.be
You will now have a serial device at /dev/ttyUSB0
3.4 balong-usbdload
Now flash the first part. I guess, it erases the stick.
root@note:~/git# ./balong-usbdload/balong-usbdload -p /dev/ttyUSB0 balong-usbdload/usblsafe-3372h.bin Аварийный USB-загрузчик Balong-чипсета, версия 2.03, (c) forth32, 2015 * Удалена процедура flash_eraseal по смещению 000004b0 Компонент Адрес Размер %загрузки ------------------------------------------ raminit 00000000 3412 100% usbboot 57700000 5922289 100% Загрузка окончена
I don't spear Russian, but this looks like success.
Your Stick will now create three serial interfaces:
- /dev/ttyUSB0
- /dev/ttyUSB1
- /dev/ttyUSB2
3.5 balongflash
Now flash the new firmware to the stick. Try with all three devices. I was successful with /dev/ttyUSB2 (the last I tried):

I guess pretty much that this means success.
