convert WiFi passwords from old Android wpa_supplicant.conf to newer (post-Oreo) WifiConfigStore.xml



This perl script reads old wpa_supplicant.conf on STDIN, and outputs new WifiConfigStore.xml to STDOUT



## Description

For me, upgrading LG G3 from LineageOS 14.1 (Android 7.1.2 "Nougat") to LineageOS 16.0 (Android 9 "Pie") resulted

in all my wifi password being lost. The reason is the information is no longer kept in

*/data/misc/wifi/wpa_supplicant.conf* but instead in */data/misc/wifi/WifiConfigStore.xml*



This script is a quick hack to convert (most of the) passwords to new format

so I don't have to remember and type them all again.



All of the project is released under Apache 2.0 license (see LICENSE file).



## Usage



* `adb root`



  (make sure you have first set permissions in developer settings root ADB)



* `adb pull  /data/misc/wifi/wpa_supplicant.conf`



   (or in whatever location it is in your device - maybe */data/wifi/bcm_supp.conf* or */data/misc/wifi/wpa.conf*)



* `./convert_wifi.pl < wpa_supplicant.conf  > WifiConfigStore.xml`



  (and check any warnings / error outputed on the screen)



* disable WiFi on your phone



* push new config on the phone (to correct location - check first where is current *WifiConfigStore.xml*):

```

adb push WifiConfigStore.xml /data/misc/wifi/WifiConfigStore.xml

adb shell chmod 600 /data/misc/wifi/WifiConfigStore.xml

adb shell chown system:system /data/misc/wifi/WifiConfigStore.xml

adb shell rm /data/misc/wifi/WifiConfigStore.xml.encrypted-checksum

adb reboot

```



Note that location of *WifiConfigStore.xml* on your device might be something other than */data/misc/wifi* (like */data/misc/apexdata/com.android.wifi*), so you need to verify that first (and update the commands above accordingly).



* enable WiFi on your phone



## Troubleshooting

* some phone require WAPI support, and others do not support it.

  If `master` git branch at https://github.com/mnalis/android-wifi-upgrade

  report errors when you try to upload `WifiConfigStore.xml`,

  try `wapi` git branch: https://github.com/mnalis/android-wifi-upgrade/tree/wapi



  This is because different phones have different config format requirements,

  see https://github.com/mnalis/android-wifi-upgrade/issues/6 for details



* if all else fails, please report new issue at https://github.com/mnalis/android-wifi-upgrade/issues



## TODO

* Never write XML by hand as I do here!  It will seem to work in most cases,

  and then break badly on some non-escaped value or similar.



* only config supports implemented currently are open networks (no PSK),

  WEP networks with up to 4 preshared keys, and WPA2 networks (with ASCII PSK);

  WPA1 may be or not be supported per chosen bit masks, but was not tested

  directly. Maybe support other (WPA1, EAP-xxx thingies)?



* set uid to 1000 or 0 ? or -1 ?



    * there are UIDs in "CreatorUid", "LastUpdateUid", "LastConnectUid",

      "CreatorName" => "android.uid.system:1000",

      "LastUpdateName" => "android.uid.system:1000"...

      are they all same or may be different?



* parse id_str (url_decode, JSON) for creatorUid & configKey ?



* where to put "priority" and "bssid" from wpa_supplicant.conf ?



    * possibly, bssid maps to DefaultGwMacAddress ?



* wpa_supplicant.conf: is "disabled" always "1" ?



* warn for all unhandled key/value pairs (or even better, handle them correctly)



* add options to select 'WAPI' (`$AllowedProtocols`) and `$ConfigKey`

  formats, instead of using different git branches (need to fix `make check`

  too then)



* FIXMEs in code
