"Huawei e3131 (Revision e3131-s2 text under SIM card place) IS nightmare
" -- indeed. But now it works
I can show you the path but you have to walk it by your self..
Stuff you need to get before:
Search google for " MobilePartnerforwindows.zip " , can be older version also. It´s not very model specific.
Install it and search for file "ewser2k.inf" it should be located at c:\program files\huawei\drivers\x86 (depends are you x32 or x64) etc.
Copy whole c:\program files\huawei\drivers\x86 directory to c:\temp\x86
Open file ewser2k.inf and search for section topic " [QcomSerialPort] "
Add following lines below section topic :
%QcomDevice01% = QportInstall01, USB\VID_12d1&PID_143E&MI_02
%QcomDevice01% = QportInstall01, USB\VID_12d1&PID_1442&MI_00
%QcomDevice00% = QportInstall00, USB\VID_12d1&PID_1442&MI_01
%QcomDevice01% = QportInstall01, USB\VID_12d1&PID_1448&MI_01
Search google for " E3131Update_21.158.00.00.1020.B757.exe " This is the only that i managed to get e3131 working (3.8.2014)

Huawei e3131-s2 device comes with never firmware already inside and I tried also with latest firmware " UTPS23.009.05.02.1020_MAC23.009.05.02.1020.exe ".
RESULTS with original or latest " UTPS23.009.05.02.1020_MAC23.009.05.02.1020.exe " inside:
USB device is detected ok by "miktotik routerboard 915g 2HnD" with fw 6.10.
You can also send AT commands to device via "/system serial-terminal usb1" and everything looks fine.
Even the dongle light will be solid blue and everything looks REALLY GOOD..
BUT that <<< #!¤%¤%!#¤% >> e3131 will always hang with ppp status "link established" and will not never-ever get WAN ip address.
3) com port communication program , for example teraterm "ttermpro.exe"
ok, suppose you now have necessary files. Let´s proceed.
hilink mode is the 1.st problem,
connect e3131 to laptop and get your self "online"
When you open yur browser to http://192.168.1.1/
you should see some huawei connection status information. Good.
Copy paste this: http://192.168.1.1/html/switchProjectMode.html
and press enter. NOTE: url IS CaPs sensitive.
Huawei disconnects to offline and windows device manager will start for searching new drivers.
Everytime point driver search manually to c:\temp\x86..
If you edited ewser2k.inf file correctly, drivers will be found ok.
NOTE: you will need to install those 3 device driver files each of 2 times.
First round is for "huawei device" and after it installs second time for device like "a65bd63245.b65d654f"
ok. If everything went ok, you should now see some communications ports devices.
is temporary change only.
If you remove/powerdown huawei e3131 device before part B) , it will go back to hilink mode.
Thanks for "nimbo78" tip, confirmed that below link for cyrillic version of "3G_Modem_Mode_Switcher_1.0\3gsw.exe" works ok and fast after clicking couple times "1.st button on the left"

Another slower way is connect to huawei e3131 usb dongle via teraterm "ttermpro.exe"
Point to device manager com port which has "user gui" description.
You can confirm that you are connected correctly by giving command AT and you should get instant reply OK.
Give command AT^U2DIAG=0 and you should get reply OK
This will change e3131 device default to modem mode instead of hilink mode
( If you need to change it back, command for hilink default mode is AT^U2DIAG=119 )
Remove and re-insert e3131 device.
If you get com ports again and are able to connect via teraterm "ttermpro.exe" everything went ok.
Install firmware executing " E3131Update_21.158.00.00.1020.B757.exe "
NOTE: during my fw "downgrade" device manager found new devices in the middle of fw update process which was paused..!
I pointed driver search to "c:\temp\x86.." and after drivers were installed ok, firmware update proceed ok.
It´s your device and also risk =)
ok, now you should have got "fimrware update succeed" notice and you are ready to connect huawei e3131-s2 to mikrotik.
Mikrotik init command is
and dial command ATDT to number *99#
After week of 24x7 testing, "huawei e3131-s2" works stable with "miktotik routerboard 915g 2HnD" with fw 6.10"
Sorry bad spelling due hurry, wish you a Good Luck, and remember Sharing Is Caring
