Qualcomm diagnostic tools
I trying to mess a little with the GNSS (~GPS) settings in the NVRAM (I want to see if the SBAS entry is there and if it's aready enabled + possibly turn it on if's there but turned off).
I tried to set the phone to "modem" mode with EFS Professional but I can't find any USB drivers what Windows 8.1 x64 accepts, so PC tools can't connect via the emulated COM port (which isn't exist without the proper "modem" driver...).
Is there a beta version of the Samsung driver pack (newer than 18.104.22.168) which supports this phone?
Is there a hidden menu inside the phone by any chance (which can be accessed without using the USB modem mode)?
By the way, it's an i9195 (T-Mobile HU) with CM10.2 nightly.
