UNLOCKING MODEM:
As usual, modems from cellular operators are delivered blocked - they can work only with SIM cards of this operator. The list of plmn-codes allowed for use can be viewed with the commandat ^ simlock? .
Of course, this situation does not suit us - we want, having bought a modem, to use it with any sim card. For this, the manufacturer laid the opportunity to unlock the modem. This is done by entering the unlock code (nlock code ), calculated by a special tricky algorithm from the IMEI modem.
Calculator to calculate codes can be downloaded here (there are versions for windows and linux).
To unlock, follow these steps :
- Calculate the unlock code using the above calculator. Of all the codes it calculates, the code is used. v201 or code v2 .
- Insert someone else's sim card into the modem (sim card of another cellular provider, not the one who sold you the modem).
- Connect the modem to the computer.
Further, the control program (for stick-modems) or the web interface (for hilink-modems) will ask for the unlock code, which must be entered. All - the modem is unlocked and will work with any sim card.
In addition to entering the code through the program and the web interface, you can also enter it via the AT command. This is especially true for stick-modems under linux.
The team looks like this:
at ^ cardlock = "unlock code" - code is used v201 or code v2

*****

RECOVERY ATTEMPTS:
The number of attempts to enter the code is limited10 attempts . If the wrong code was entered 10 times, the modem blocks further attempts - more, the at ^ cardlock command will not unblock it, even if you enter it with the correct code. If you still managed to exhaust all input attempts, that's okay - they are easy to recover.
This is done by such teams.:
at ^ datalock = "unlock code" - code is used v201 or code v2
at ^ maxlcktms = 10
10 is the new number of attempts (you can enter any number from 1 before 255 ). You can then enter the command at ^ cardlock with the correct code and unlock the modem.

Total:
consistently enter AT commands from top to bottom:
at ^ datalock = "NCK code" - code is used v201 or code v2
at ^ maxlcktms = 10 - you can enter any number from 1 before 255
#
at ^ cardlock = "NCK code" - code is used v201 or code v2


Attention!!! Huawei modem E3131 Beeline with firmware 21.157.31.00.161 - the code does not unlock. It can be unlocked by this (21.158.00.00.1020) firmware. Thank you so much Kulibin y

Hi, I can’t pair the GU in the car with a whistle, the VINSE system just does not see it, it seems to me that because of the incorrect AT command, the modem is not switched to only modem mode, who will tell you the correct command?

This model does not need to be flashed to unlock! just get the unlock code in the topic on the forum:Here you can get device unlock codes for FREE.

With a new bug it works faster, holds a weak connection more steadily.

A similar problem .. But! In win7 first determine how to correctly set the composite device with built-in cd firewood, put the "modem only" (says ^ GETPORTMODE: TYPE: WCDMA: huawei, MDM: 0, DIAG: 1, PCUI: 2). Then in w7 sees two com (type all ok) modem port. BUT: The State (CE 6.0) to the host USB - silence (not determined a new device), on port State for flash drives sees this device as the sd, in WIN XP is defined as a composite device, see SD and CD-ROM, modem no (clear firewood not :))! Offers to run the wood from Beeline c virtual cd-rom (as it and be something should not!), The modem will appear after the inspiration for the vision in XP, (and again asserts that negno only mode modem!) And a virtual cd-rom disappeared, but it It does not solve the basic problem in the CE. Help who than can .. :)

Total:
After the demolition of wood Beeline - again composite device, cd-rom + SD: (ie: regardless of the modem configuration on an XP system, (WIN7 like a little differently) without firewood device is defined as a composite device, regardless of the used commands from the post # 3, if the wood has - at the teams submits, if the wood is not - automatically defined as a composite, regardless of what shows getportmode, and for the Council of Europe is unacceptable, ie there is a device in general is not defined -.. probably need additional modem commands. and other dances with a tambourine IMHO. Help someone than it .. :)

Huawei E3131 - turn off Hi-Link mode and switch to modem mode

To disable the modeHi-linkon the modemHuawei E3131 go to
http://192.168.1.1/html/switchProjectMode.html

The modem reboots and two serial interfaces appear.
And then enter the following command in the modem in the console:
AT ^ U2DIAG = 0

If this is successful, he will respondOk.
To return to modeHi-link- send the following command:
AT ^ U2DIAG = 119

The modem requires disconnecting and reconnecting for the changes to take effect.
Working in modem mode, it will change its Prod ID and will look like this (in lsusb):
Bus 001 Device 082: ID 12d1: 1c05 Huawei Technologies Co., Ltd. E173s 3G broadband stick (modem on)

If you do not have a virtual terminal, it is created when you insert the device.
From there, you can already type in the console, such as in / dev / ttyUSB0:
echo "12d1 1c05"> / sys / bus / usb serial / drivers / option1 / new_id

Huawei E3131 - Disabling HiLink and turning into a dialup modem
Huawei E3131 - Disabling HiLink and turning into a dialup modem

I have been trying to retain my HiLink and reverting my new
Huawei E3131 dongles back to dialup modem based operation of previous dongles.
First step is to enable the serial console. Visit the following webpage
http://192.168.1.1/html/switchProjectMode.html

The modem will now be a rest of the serial interface.
If you are using a baud rate of 9600bps for example, use a terminal client of your choice.
I used minicom, which is available in most distros repos. And type the modem the following command.
AT ^ U2DIAG = 0

If this is a success.
Function in modem mode when plugged in.
To restore its HiLink functionality. Do the same and send the following command instead.
AT ^ U2DIAG = 119

Once the device has had its mode changed in this way.
It requires removing and plugging back in to take effect.
ID and it should look like this (lsusb)
Bus 001 Device 082: ID 12d1: 1c05 Huawei Technologies Co., Ltd. E173s 3G broadband stick (modem on)

If you don’t have a virtual connection.
It follows
echo "12d1 1c05"> / sys / bus / usb serial / drivers / option1 / new_id

From there you can dial out as accustomed using the first created virtual tty. eg, / dev / ttyUSB0

I do not have a router, sohttp://192.168.1.1/html/switchProjectMode.htmlI don’t understand what Hi-link mode is I don’t understand .. Once again: firewood is installed from the beeline, the modem is switched to modem only mode (AT ^ SETPORT = "A1, A2; 1,3,2" command from post 3), confirms its new mode ^ GETPORTMODE: TYPE: WCDMA: huawei, MDM: 0, DIAG: 1, PCUI: 2, but after the removal of firewood when stuck, it is again defined as a modem + CD + SD, which does not suit ...



Rep: (5)
I bought the E3131-Beeline in the office. I installed the firmware E3131Update_21.158.00.00.1020.B757 (initially 21.157.31.00.161) and unlocked it. I pushed the SIM from MTS. The program (of) did not find the SIM, then I read that I need to update DashBoard. Updated and now he does not see the modem at all: lol: (Modem CD-ROM only)
How to recover?

on which dashboard updated?
get the software update for the modem from the off site of MTS under win 8 and everything will work for you

Updated ON "Huawei modem plus"
If it’s not difficult to specify a link (not found), and even if you try to determine the dc-unlock modem or other programs, it is not detected.

program to update the port do not find

AT team for Huawei E3131
your modem is NOT Hilink; you don’t need to go to the specified address for it.
just apply at command



Rep: (5)
Rash_b @ 06/08/2013, 09:00*
apply at command

What kind ?
These do not help

Rep: (5)
Good day to all. There is Huawei E3131 (420D) from MTS, I want to buy a stationary Wi-Fi router for it, but I can not find anything anywhere which routers support it. I wanted to take ZyXEL Keenetic 4G, there is an impressive list of supported modems, but there is exactly E3131, technical support also did not confirm that it would work.
If there are users of this device with a router, share pliz.



Rep: (21)
I tried with a mobile HAMA router with ebay, the one that is using the battery, 100% worked.
