Ok I think my modem is not a standard e353 any more. I flashed the firmware linked successfully but the modem still doesn't work. The light flashes green but then doesn't switch to blue like it is supposed to.

I have an identical working model next to me. Am I able to read the firmware out of the good one and load it into the bad one to get it working? My guess is that my carrier ordered a special version of the device just for them.

The full model number of my modem is e353tu-6. And the firmware version of the working one seems to be newer than all of the other ones I've been able to find.

Yes according to Mobile Partner the IMEI matches what is printed on the box and the modem.

The firmware version that I have installed in the modem is 11.810.09.20.264 however the firmware in the good one that I also have is 11.810.13.02.302.

Any more ideas?

That did the trick thanks. If only I could find a firmware that has voice support. This is the main reason that I bought the modem in the first place.

Correct. According to dc-unlocker there is no voice support in the firmware. Any ideas where to get a version that does support voice?

Thanks for helping me out by the way. At least I have a working data modem again. Would be nice to get voice capabilities as well though

Huawei EM820W

Hi there,
Thanks for sharing that nice development !

I've a nice problem to resolve.
Due to 3G android RIL issue (3G disconnections with USB falling to another PID) I've removed the EM820W from the tablet.(original f/w 11.810.09.19.00)
Original vid : 12d1 pid: 1404
I've unfortunately flashed it with the last Huawei official f/w rel 11.810.10.02.00.
This has turned the modem into an MBIM modem compatible with Win8 only !
New vid: 12d1 pid :1571
I've been able to switch the modem back to a standard mode with Win7, hacking the drivers.
Now it shows the USB virtual COM ports and dc-unlocker can talk with the modem.
Here is what it shows:
Quote:
selection :
manufacturer - Huawei modems
model - Auto detect (recommended)
Found modem : EM820W
Model : Huawei EM820
IMEI : 33333333333333 (faked IMEI)
Serial NR. : W9V5TB1211813526
Firmware : 11.810.10.02.00
Compile date / time : Jan 16 2012 09:50:02
Hardware ver. : MD1EM820WM
Chipset : Qualcomm MSM8200A
SIM Lock status : unlocked
Wrong codes entered : 10 (unlock attempts left : 0)
Now the question is how to flash the modem back to an older release?
I've a firmware file that looks correctly extracted by your flasher.
Unfortunately Huwaei flasher returns 'No response from Com port'
It reports a 3G PC UI Interface (COM13) which looks correct when I check in the device manager under USB controllers.
The modem diagnostics in the device manager does return the correct information, and dc-unlocker can also communicate with the modem.
I've tried to run revskills as advised in an earlier post but to no avail.

Any suggestion to resolve the communication error ?

Thanks in advance.
Yves

Config : Win7 Pro - .net Framework 3.0 3.5 and 4 installed
Modem in mini Pci-e slot dedicated to Wifi

Huawei EM820W (follow-up)

Interesting !
Now the modem can communicate with Huawei flasher.
For some reason likely due to the MBIM config, there were two modem instances in Device Manager:
Under Network cards:
- HUAWEI Mobile Connect - 3G Network Card #2
Under Modems
- HUAWEI Mobile Connect - 3G Modem

I've disabled the first instance to keep only the modem enabled.
Now Huawei flasher returns:
Quote:
Reading info ..OK
-------------------------------------------------
Firmware:11.810.10.02.00
Hardware: EM820W_1G MD1EM820WM Ver.B
Imei: 33333333333333-3 (fake IMEI)
-------------------------------------------------
It looks better and promising.
I'll keep you posted on further progress.
Regards
Yves

First of all, I would suggest you to install the latest Huawei modem driver.

Second, look at results of AT^SETPORT? and AT^SETPORT=? commands execution.

Question: Why didn't you try to flash your modem in a usual way, i.e. with original EXE-updater?

Huawei EM820W (follow-up)

Hello vve,
Thanks for your reply.

Since the modem is now MBIM compatible it has a totally different behavior.
Only Win8 can play with such a beast .
I cannot use the usual EM820WUpdatexx.xx.xx.xx.xx.exe because :
1- I've not found that update.
I've only the Android update files that are also correctly parsed by Huawei flasher.
2- As the modem is in MBIM mode, as soon as there is something changing in the driver, i.e. switch to diag or PC UI mode or whatever, I'm loosing the communication as all USB Com port are disconnected. This is really tricky.

I've tried to to flash the modem with Huawei flasher 1.1, but the same problem occured.
As soon as Huawei flasher has switched the modem to another mode for programming, I've lost the communication. (the 4 USB com ports have vanished in the Device Manager.)

When Huawei Flasher has switched the modem for programming, the vid/pid have changed from 12d1/1571 to 12d1/1568 which is normal for firmware updates ,I guess .
( same behavior in Android but former vid/pid were 12d1/1404 and 12d1/1003)

Now the question is :
what drivers do I have to see in the Device Manager when in firmware update mode.
If I know that I will try to hack the driver so that it will not loose the communication.
During my first test, it returned to MBIM mode.

I told you that it is an interesting question !
Never update a modem to Win8 MBIM if your intent is to use it with another OS.

Regards
Yves

BTW, thanks for the new drivers. I'm using hacked driver version 4.20.05.00. Will check what's new in the new driver set.

Again, have you installed the latest drivers?

What about AT^SETPORT?

Huawei EM820W (continued)

@vve,

Yes I will use that driver set. Thanks.
I'm analysing the drivers and will use them. Report soon.

However, I've to hack them as they don't include yet the new vid/pid.
Try VID: 12D1, PID:1568 in Google !
This is the reason why I need to know wich drivers are being used during the update process.
Up to now, everything is OK, but I'm loosing the com ports as soon as the HF switches to update mode.
The modem returns to the Win8 MBIM configuration with another vid/pid.
This is a totally new modem mode ! Very easy with Win8, very annoying with other OS !
It's really difficult to switch it to the standard Win7 or older mode.
I suppose HF will use these drivers during the update :
ew_hwupgrade.sys
w_hwusbdev.sys
But perhaps others ?

Regards
Yves
