This setting can be reverted using the `--enable` flag to turn on SUPL TLS again.
Note: For a working TLS protected SUPL request you need updated root certificates in your modem (see option 2).
Now that you disabled SUPL TLS transport you must change your `gps.conf` file.
It can be located at `/etc/gps.conf` (Xperia X, ...) or `/system/vendor/etc/gps.conf` (Xperia 10 II).

#### Option 2: Upload additional ROOT certificates ####
Well, if only Google should know your SUPL request data you should use SUPL TLS transport which is the default modem setting without patching.
However to get this working you need a valid root certificate injected into modem via QMI but missing libhybris bindings and libgeoclue parser support for gps.conf file will not allow this at the moment so you have to upload the required certificates to modem manually.

#### It's not working for me ####
I've tested `suplpatch` with Xperia X and get an A-GPS fix in less than 10 seconds even if the device wasn't using GPS for many days and ephemeris data was expired.
#### A Word On 4G SUPL Support ####
If your device is connected to a 4G network (LTE) **SUPLv2** is mandatory to query the SUPL host and make things working. Sadly SailfishOS currently has no configuration options for this and hybris bindings to override the modems default setting when GNSS services are started.
Deactivation of SUPL TLS was verified by proxying requests from a public server to supl.google.com and examing the requests. No TLS hello package or other handshake overhead was send so TLS deactivation works as expected.
A solution for this is to change the modems default SUPL version from v1 to v2 using the `--supl` flag.
```

I've tested `suplpatch` with Xperia X, X10 Mark 2 and X10 Mark 3 and get an A-GPS fix in less than 10 seconds even if the device wasn't using GPS for many days and ephemeris data was expired.

#### Pro-Tip ####
If you don't worry about your privacy you should simply disable SUPL TLS as TLS handshake uses more traffic than plain SUPL request/response itself.
@ -193,10 +234,23 @@ _Is this an official tool released by Jolla?_
- **NO** it's a community members attempt to help fixing your A-GPS problems
_What does `ERR: Unable to open '/dev/diag' device (ioctl DIAG_IOCTL_SWITCH_LOGGING fails (12)).` mean?_
- Your modem driver has some problems and you should reboot your device to fix it
- Please check your --aosp value as it must match the Sailfish OS AOSP base (this is NOT the Android base used in aliendalvik container!). E.g. Xperia 10 Mark 2 is AOSP 10, Xperia 10 Mark 3 is AOPS 11 where the intial Xperia X uses AOSP 6 as Android base.
_How do I ... on my phone?_
- If you are not familar with Linux shell or editing tools please wait for an official A-GPS solution by Jolla
_Can you add feature ... into the tool?_
- This is not a hacking tool for your device modem so don't expect to see VoLTE/VoWifi profile modifications or unlocking of locked radio bands ever
_Is this working for Jolla or Jolla C phones?_
- Sorry but it's sadly not working (modem security / diag driver issues)
_Is it working for 4G networks?_
- To get SUPL working with 4G networks please set the default modem SUPL version to v2 (--supl 2)
#### Changelog ####
v0.0.2.0
- Added support for AOSP base 11 to get `suplpatcher` working with Xperia 10 Mark 3
- Added a new flag to modify SUPL modem default version (needed for 4G SUPL support)
- CyberTrust and ISG root certificates created for second subscription (SIM2)
