Types and features of modem firmware:

COPY(with a small edition) . ORIGINAL .

For this modem, there are 2 fundamentally different types of firmware - STICK and HILINK. Firmware interchangeable, that is, in any modem you can flash any firmware.

STICK

With this firmware, the device behaves like a classic USB modem: there is a command AT-port through which you can establish a connection using the PPP protocol (RAS). This is how almost all previous-generation 3G modems work. The speed is limited - no more than 20-30 Mbit at the reception. In addition to the PPP mode, there is an NDIS mode. In this case, the modem emulates a network interface through which data is transmitted, and only control commands are sent through the AT port. In this mode, the speed is not limited. The main feature of the stick mode is to establish the connection and support the operation of the channel using the OS of the computer to which the modem is connected. At the same time, the computer receives an IP address directly from the cellular provider through a DHCP request, and the modem acts as a network bridge, transmitting the packets from the computer to the cellular network and back without changing them.

The initial USB stick stick composition is a virtual CD-ROM and microSD card reader. In order for modem ports to appear, you need to switch the composition. Under windows, this is done by carrier software available on a virtual CD, or by the huawei proprietary program Mobile Partner. Under linux, switching is done by the usb-modeswitch program. It is possible to prohibit the transformation of songs. This is done with the following command:

AT ^ SETPORT = "FF; 1,2,3,16"

In this case, the modem immediately after switching on will look like a modem, 2 AT ports and a NDIS network card. CD and microSD will be excluded from the configuration. This mode is extremely convenient for using the modem in various home routers. To switch back the composition with switching, use the command:

AT ^ SETPORT = "A1, A2; 1,2,3,16, A1, A2"

Version numbers of stick-firmware always start at 21 — for example, 21.318.05.00.00.
Included with the Stick-firmware, the so-called Dashboard is flashed into the modem - an image of a virtual CD that appears in the system after the modem is connected. On this CD are the modem drivers for different operating systems, as well as a control program with which they establish a connection to the Internet, read SMS, make USSD requests, etc. There is a universal version of this program from the manufacturer of the Huawei modem (Huawei Modem), as well as specialized versions from specific telecom operators.

HILINK

With HILINK firmware, the modem works in the router mode and is presented to the computer as a network interface (usb-ethernet-rndis). The computer receives network settings from this interface via DHCP, and then goes through it to the Internet, like through a regular wired LAN. The modem assumes all care for establishing a connection and maintaining the channel, the computer does not even notice that access to the Internet is through a cellular network. In this mode, the modem has its own local IP address (usually 192.168.8.1), visible from the computer as a default gateway (default route), as well as an external IP address obtained from the cellular network. Routing is performed between the network of the cellular provider and the local network (modem-computer) using the address translation mechanism (NAT). Provides port forwarding from the external network (port forwarding and DMZ).
The modem is configured in this mode via the WEB interface available in the modem and accessible via its local IP address. Also through the WEB-interface information is available on the state of the modem and the signal of the cellular network, connection management, reception and transmission of SMS messages and USSD commands, SIM menu and much more. This is especially valuable for Linux users, as well as for those who have a modem connected not to a computer, but to a home router. Modem configuration via AT commands, as in stick firmware, is not performed in the normal mode of hilink firmware, although it is possible in the special DebugMode debug mode.

The initial HILINK modem USB composition is exactly the same as that of the stick - a virtual CD-ROM and microSD card reader. Switching tracks under windows is a small program mbbservice, run from the built-in CD. Under linux, this is done by the usb-modeswitch program. Regularly modem developers do not provide a mode without switching tracks. Nevertheless, it is possible to make such a mode by some modification of the firmware. At the same time, the built-in SD card reader is lost, however, it becomes possible to use a modem with any router that supports usb-rndis network cards.

Version numbers of hilink firmware always start at 22 — for example, 22.318.05.00.00.
HILINK firmware consists of two parts - the firmware itself, and the WebUI (web interface). The first firmware is the main firmware, then the WebUI.

Unlock modem. Recovery attempts to enter.

COPY(with a small edition). ORIGINAL.

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

Tell me, how did you achieve the work of the Dir620 and E303?
I burned zte192, who worked in conjunction with the kinetics of 4g, took in the Euroset to replace 303 not tied to operators, but they did not make friends with the kinetics. I read your post that works out of the box, took 620, flashed 1.3.3 ... and he does not see 303 (

Also it is not at all clear how to enter AT commands in 303?


help out

Yes, there is no wisdom there, the latest firmware, no AT commands are needed, after the firmware, make a reset on long and then create a session with the data of the opsox

The modem does not connect! Please describe in more detail how. (and most importantly, why with the data of the opsox if the authorization on the modem passes?)
And do not throw off, maybe the config so that everything coincides with me exactly?

At the same time in the Dc-unlocker included the ability to call / answer.

Tell me how and at the same time how to disable flash download (only modem) in Dc-unlocker did not see these items. plz! And how to install a dashboard.
Thank.

So I understand Huawei has 2 different E303 modemsMobile Broadband
1 - uses "technology"Plug and playand can work with mobile partner
2 - uses "technology"Plug and surtand has a web interface
... for example, my Mobile Partner does not see the E303 HiLink ...
... of course, I can do what I’m doing wrong, but as far as I understand, the Mobile Partner dashboards from the E303C are not suitable for the E303 HiLink (and most likely it shouldn’t, since these are two modems of different design features).
... of course, and for the E303 HiLink, there are dashboards that are different for different cellular operators, and the Huawei E303 HiLink is the most likely to have a native dashboard, so to speak - but where can I get it?

People who could activate voice communication ..., or who was able to deliver the dashboard described above (http://genuess.vx6.ru/huawei_e303_c_driver(dashboard) )
when I try to install it, I can’t find the port ("Error code 10: port not found"), did anyone have such problems?

Perhaps this dashboard is not suitable, but nevertheless also could not find the "native" (

People who could activate voice communication ..., or who was able to deliver the dashboard described above (http://genuess.vx6.ru/huawei_e303_c_driver(dashboard)) when I try to install it, I can’t find the port in any way (“Error code 10: port not found”), didn’t anyone have such problems? Maybe this dashboard doesn’t fit, but nevertheless also couldn’t find “native” (

He did not deliver, I wrote above ... The thing is that in the above dashboard there are no drawers for E303 HiLink, so the installation’s “Vizart” cannot be installed (I apologize on the laptop the letter “y” does not work, but to write with Using the on-screen keyboard is inconvenient) not only the port, but the device as a whole ...
I have a Web UI for the E353 (which came up for the E303 HiLink) version 11.010.05.03.5021 from the company "Three", so when you put it you do not need to disconnect anything," Vizart "will install a draver instead of a network port 2 com will appear, it is properly put on and, accordingly, everything will be installed, after which "Vizart" will return the network one.

[ART_SHA]

Then please tell me where you can download this Web UI.
And as I understand it, with the help of it, you can “recognize” the E303 for all things? Specifically, I am interested in the possibility of voice activation.
P.S. on the website of the company Three honestly did not understand :)

[alex1299]

also e303 hilink stitched web from e353. Now the above ports are included as follows:
http://192.168.1.1/html/switchProjectMode.html
Most likely, they were also included before. But the benefits of this are few. Dig further.

[alex1299]

only one port is enabled during the upgrade: "pc ui interface". What is there for the data is transferred, I do not have enough knowledge to understand, but what is interesting, at the beginning of the update, the response of the device is this "7200B-SKCBADZMГѓ {~~: ВЎn ~~ EHUAWEI E173". Neither the E303 nor the E353 is found at all. Probably, you need to look at the e173 thread ..

alex1299 @ 07/31/2012, 18:47

also e303 hilink stitched web from e353.

For God's sake, explain in more detail how I stitched. For the entire forum and give a link to the firmware.
