In to other word, I can not even switch to initial mode using usb_modeswitch?
Ok, I will try to reset using AT commands

usb_modeswitch is made for switching from default mode (install mode) to target mode and not the other way around.
It is unusual that a stick doesn't return to default mode when re-plugging it, I have only seen that before when a user has disabled the cd-rom with AT^UDIAG commands. No cd-rom - no default mode.

[ursus]

Bingo!

I couldn't imagine that modes could be switchable using AT commands.
I dosvered that HiLink mode can be switched to serial, using http://192.168.1.1/html/switchProjectMode.html
from this blog http://blog.phoenixhaven.net/category/haxx/
But I couldn't understand why there was reference to 12d1 1c05 so I decided it is related to some other revision of E3131

now as @LOM suggested I tried AT command
and used AT^U2DIAG=0
now my E3131 is always in 12d1 1c05 mode

Here is a list of other Huawei modes:
AT^U2DIAG=0 Modem Mode
AT^U2DIAG=1 Modem and CD-Rom Mode
AT^U2DIAG=255 Modem+CD-Rom+Card-Reader Modem+ Factory Defaults Setting
AT^U2DIAG=256 Modem+Card-Reader Mode
AT^U2DIAG=257 Disable Application Port
AT^U2DIAG=276 Reset to factory Defaults

AT^U2DIAG=119 to return to HiLink mode

ursus, I tried the same command it works with me also and I have now Product ID 1c05.

Now the conclusion is that I have tree different ways to switch the usb modem to serial port each one has different target Product ID

12d1:1001 (using MessageContent 55534243123456780000000000000011060000000000000000000000000000)
12d1:1442 (Using http://192.168.1.1/html/switchProjectMode.html)
12d1:1c05 (Using At Cmd AT^U2DIAG=0)

If as LOM said 1442 serial port interfaces are for maintenance and and diagnostics purpose.
Why their exist both 1001 and 1c05 ?
Why the modem didn't convert from cdc ethernet (12d1:1f01) to target (12d1:14db) when using MessageContent 55534243123456780000000000000011060000000000000000000000000000, as LOM said, but instead (12d1:1001) ?
What if switchProjectMode is not exists and I can't use command like AT^U2DIAG=0, how can I know that a specific MessageContent can be used to convert the modem to serial ports (if no way is known to let the windows driver to convert it manually to serial port mode), I mean is it just tring different MessageContent and see the result ?

I think you need to realize that the vendor never intended you to play with these commands at all. The only supported mode switching is the one done by the Windows software installed when the device is first plugged into a Windows machine. That is the only mode which is safe to use.

usb_modeswitch can be configured to send the exact same command the Windows software sends. This is safe, and allows the device to be used the same way in Linux as in Windows.

Any other mode is unsupported and can potentionally make your modem permanently unusable. The vendor may have implemented a number of different modes in addition to the supported mode. Which product IDs these use are completely up to the vendor to decide. But the fact that these modes exist does not mean that they are supposed to be used by any end user. Feel free to experiment, but be aware that some of the modes can be a dead end. Some of them are most likely only intended for firmware development or device testing. And there is no official documentation for any of this. If you get stuck, then you are on your own.

Hi
I have a Huawei E3131 , and I want to unlock it, but the issue is that I don't know how to use and send a MessageContent like "55534243123456780000000000000011060000000000000000000000000000"

which switches some 12d1:1f01 versions into 12d1:14db with serial type interfaces.

knowing that I work under windows 7 !!

[Josh]

Did you have a look at the usb_modeswitch main page?

[yassine]

Thanks for your reply, I have worked with it, but when I executed it, the system appears a message error that the System can't recognize the Dongle ! Unlock !

[Josh]

That is the whole point of mode switching. The "old" device is going away, and a new one appears.

Check the result with "lsusb", before and after.

[yassine]

thank you, can you please explain to me more, because I don't understand how can I work with it !

Hi,

i'm also trying to switch a E3131 into a serial device with usb_modeswitch on a raspberry pi on wheezy. I need to do it without using the page http://192.168.1.1/html/switchProjectMode.html .

lsusb tells me: 12d1:1f01

If I visit the page on Windows, the devide is switchting to: 12d1:1442 with two unknown devices, I can't find any drivers to get a serial port under windows.

So i tried to use usb_modeswitch an the raspberry to get the two tty devices, for using at cmds:
usb_modeswitch -W -v 12d1 -p 1f01 -V 12d1 -P 1442 -M "55534243123456780000000000000011060000000000000000000000000000"

But this doesn't work:

I tried also many other combinations of target pids and meassage contents, without any changes.

Josh, can you help me, please? If necessary, i can send a E3131 device to you.

Best regards from Stuttgart
Dom

[Josh]

"Doesn't work" means that the USB ID does not change - did I get that right?

[dom]

Yes, no change of the PID.

[Josh]

Hmm, if you are runing manually, there may be an improvement when adding the -I parameter.

[dom]

Thank you Josh! That's it!

This cmd switches the E3131 directly into modem mode:

Code: Select all

usb_modeswitch -W -I -v 12d1 -p 1f01 -V 12d1 -P 1001 -M "55534243123456780000000000000011060000000000000000000000000000"
