Malformed settings file will cause infinite boot. #13
Description
Weekly release 20180610 on my 3T causes a bootloop when downloading and flashing from system update(bia twrp bluespakv8.61) on my 3T. System was not shutdown since 20180603, so the bug may have be introduced then. Downloading and dirty flashing older weeklies did not restore my system. Wiping dalvik cache after each flash.
Watching the logcat shows the following repeatedly (causing the infinite boot):
06-10 21:18:25.325 6637 6637 E SettingsState: Failed parsing settings file: /data/system/users/0/settings_ssaid.xml

Investigating the file I found a malformed entry. After fixing the entry system boots correctly. I don't know what caused the malformed entry, but a malformed settings file will prevent the system from booting. The malformed entry was for an application installed yesterday. System was flashed today. There was no reboot between application install and system flash.
Malformed entry looked like this:
...
<setting id="61" name="10216" value="<PACKAGE-VALUE>" package="<COM.PACKAGE.PACKAGENAME>" defaultValue="<DEFAULT-VALUE>" defaultSysSet="false" tag="null" />
</settings>id="64" name="10218" value="<PACKAGE-VALUE>" package="<COM.PACKAGE.PACKAGENAME>" defaultValue="<DEFAULT-VALUE>" defaultSysSet="false" tag="null" />
</settings>
The DEFAULT-VALUE, PACKAGE-VALUE and COM.PACKAGE.PACKAGENAME are replaced with with specific applications to my installation. You can see the </settings> tag is embedded inside of the last package tag. The last package is still installed on my system, however I did uninstall some applications after installing that package (packages that had been installed before and after that package).
