Qualcomm DIAG/Modem drivers for Xperia PLAY

---

After I seen two threads regarding QPST/CDMA Workshop, I decided to give it a try too.
However, I had the problem with drivers, which I luckily solved.
Drivers source: http://catalog.update.microsoft.com/...b-1c1e40cfc14c

So, here's the solution for everyone:
1. Unzip the attached archive.
2. adb shell, su, echo 1 > /sys/devices/virtual/usb_composite/modem/enable
3. Open Device Manager. Under unknown devices you'll find two "SEMC HSUSB" devices.
4. For both, install drivers from the folder.
You'll get unsigned driver warning, ignore and continue with installation.
5. Reboot phone.
6. adb shell, su, echo 1 > /sys/devices/virtual/usb_composite/diag/enable
7. QPST/CDMA workshop should detect the phone now.

I won't link QPST (I don't know if there are any copyright barriers), but you can find it extremely easy on Google. You want QPST 2.7 build 355.

If you're asked for SPC code, it's default 000000.

Now, I need testers: anyone with locked bootloader, or bootloader unlocked with Omnius/SEtool, please open EFS Explorer and tell me if there's anything inside cert, client-cert and client-key folders. Alternatively, try to find any SE/SEMC certificates in EFS.

Best regards

Strange. What error are you getting?

Thanks no error messages at all!

Good. Is your bootloader locked?

No new hardware are detected, even with modem enable set to 1

Just turn on modem mode and install provided drivers for both HSUSB devices in Device Manager.

When I set the modem to 1 the adb stop working and the sa102 dissapear from the device manager but there is now new hardware detected.

Yes, that's what should happen - you should have two or three HSUSB devices under unknown ones. Install drivers for them.
