Hi guys,

I am looking for some info about how to enable Diag Mode, in order to get to the phone through QPST+QXDM. But until now, I got Nothing...

I read some post, but most of them refer to HTC devices. Does anybody knows if we can get connected to the Sony's Qualcomm Chipset? I am trying to do something similar to what ASCOM TEMS Invertigation kit does, but using Qualcomm environment.

Link Here!

Also this is the info that I have from Sony's Neo V chipset: Link Here!
Thanks!
Bonzi

Good info, but the path that it mentions is not available in my ROM, It also doesn't specify which Rom should we use. (I am using 4.0.4 Pureness)

adb shell, su, echo 1 > /sys/devices/virtual/usb_composite/modem/enable

shell@android:/ # find / -iname *modem*
/system/usr/share/alsa/pcm/modem.conf
/sys/devices/virtual/android_usb/android0/f_modem >> /device >> Link a > /sys/devices/virtual/android_usb/android0/f_modem/device
/sys/class/android_usb/f_modem
/sys/module/smd_pkt/parameters/modem_wait_timeout
/sys/module/msm_rmnet/parameters/modem_wait
....

# find ./ -iname *enable*
./platform/chargalg/power_supply/chargalg/enable_monitoring_ambient_temp
./virtual/timed_output/vibrator/enable
./virtual/android_usb/android0/enable
....

I found the path in 2.3.4 but when I activated the adb link fails and I have to reboot the phone. Could it be because the BootLoader is Locked?
Any DEv that could help me ?

Also there is a Diag folder on /sys/devices/virtual/usb_composite/ folder. I changed the enable flag to 1 and the phone disconnect the adb session...

Thanks
