This is the important part that you may want to try using device manager on your PC to find the WWAM Modem COM Port:
Ok all is solved with the EM7565. I'm not sure how much I was originally doing wrong but here is what ended up working and it's basicly what everyone said to do.

Put em7565 into mbim using putty on Windows.

You will see the com port of the em7565 under device manager under modem.

Log into putty using serial and choose that com

Usb comp needs to be 1,3,1009 or you could do 1,3,100D

At!entercnd="A710"
at!usbcomp=1,3,1009
at!reset

I chose 9 as that's what everyone else did.

Next change the script from jhend up above using vi or a good text editor in winscp

Then create a startup script of this under system startup.

echo "1199 9091 0 1199 9079" >/sys/bus/usb-serial/drivers/qcserial/new_id
exit 0

I'm sure there's a better way than a startup script. I'm sure jhend or DM can add that in somewhere.

Don't copy and paste. You get hyphens instead of minus signs.

Everything works as intended.
As for the startup script, the corrected script mentioned above is:

Code: Select all

echo "1199 9091 0 1199 9079" > /sys/bus/usb-serial/drivers/qcserial/new_id
exit 0
But, I really believe those PID/VID's are already included in the newer GoldenOrb firmware and I am not sure what purpose they play.

However, you could always enter it and reboot, and then delete the script when it is no longer needed.

And, as a last resort, there is one more option.

Several (including myself) have successfully used this method to restore the Modem composition on the MC7700, MC7354, EM7544, and MC7455 (and probably a few others). It has, however, never been tested on an EM7565.

I extracted and used some of the files from the newest Sierra Wireless drivers to prepare this work around. It may work and it may not.

There is also the chance it could brick your modem so use at your own risk.

1. Download the contents from HERE and place in a folder on your desktop.

2. Extract (unzip) the ModemFix.rar file to obtain the ModemFix folder.

3. From your PC Control Panel, uninstall the Sierra Wireless Mobile Broadband Driver Package.

4. Shut off the PC (not reboot) and then, after a couple of seconds, power back on.

5. Drag and drop (or copy and paste) the folder “ModemFix” on the PC’s "C:\" drive.

6. Plug the USB adapter with modem into the PC USB port.

7. Open a the Window’s Command Prompt (“cmd”) to run as Administrator.

8. Run the follow command:

Code: Select all

cd C:\ModemFix
9. Then, run the command:

Code: Select all

driver.exe WIN8BUSDriver=1 USBCOMP=8 DisableUsbCompAutoUpdate=1 GPS=1 GPSAUTO=1
10. Follow the prompts to install the Sierra Wireless package.

11. Reboot PC.

12. When the modem comes back online, update the EM7565 modem firmware using the GN2_999…. firmware file.

13. Re-flash the modem a second time using the same GN2_999…. firmware.

14. With any luck, your WWAN modem COM port is back.

I did the same mistake of typing 1,1,1009 instead of the 1,3,1009. Unfortunately my modem does not go in QDLoader mode - it shows the DM and NMEA ports but no QDLoader. in Windows the "Snapdragon" is showing with a band under the "Other drivers" section (No compatible driver found).

Is there a way to hardware reset the modem?

The ftd2.exe fails because it cannot find the modem either

Hi Jim,
I received my USB to M.2 adapter today and attempted to follow your EM7565 restore AT commands tutorial.

When I get to the fdt2.exe step I get the following output:

The trick from Rooter did work. I had to do this:

echo 1199 9091 > /sys/bus/usb-serial/drivers/option1/new_id

on my WRT and the connect with picocom /dev/ttyUSB0 and set the correct 1,3,1009 and I got my modem back!

Thanks!

One of the members on the Hacks Facebook group, clarified how to fix the issue of losing the Modem COM port. Coupled with the post above, we will help to better describe the fix.

The modem can fixed while installed in or behind a router running OpenWRT/GoldenOrb/WiFiX firmware.

Using PuTTy, login the router using the IP address 192.168.1.1

Once in, run the following command:

Code: Select all

echo 1199 9091 > /sys/bus/usb-serial/drivers/option1/new_id
Then repair the config with:

Code: Select all

picocom -b 115200 /dev/ttyUSB0
Then place the modem in MBIM composition with the follow commands:

Code: Select all

At!entercnd="A710"
At!usbcomp=1,3,1009
At!reset

And, that should do it.

I just put together a WE-826-T2 with a EM7455, the Mini PCI-E to M.2 (NGFF) Key B Adapter with Top SIM Card Slot with the pigtail jumper cables.

I tried both wefix goldenorb files. But it always says modem present not connected. I've tried an att sim and a verizon which are both working on other routers.
I've been reading all day and it seems like this thread would provide a fix but I can't login via PuTTY. Is there a tutorial for that? Thanks

Going to MODEM > MISCELLANEOUS > AT-COMMAND TERMINAL, are you able to issue any AT Commands?

It won't let me input any AT commands. When I type one in, it disappears and nothing happens.
