thanks to the /system partition I downloaded using SP Flash Tool, and mounted with mount -o loop ~/Downloads/system.img /mnt, I was able to find out where the Adups FOTA app was hiding using apktool and looking at the manifest and resources. it's under the innocuous-looking name Wireless Update. sly bastards. I notice it's no longer showing on my primary phone, but still is on the backup. no idea why the discrepancy, I did the same actions on both phones.
how to find it: look at the AndroidManifest.xml file under the <application> tag: <application android:allowBackup="false" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:largeHeap="true" android:name="com.adups.fota.MyApplication" android:supportsRtl="true" android:theme="@style/Base.AppTheme">. if, as here, you see @string/app_name you then need to look at res/values/strings.xml to find it: <string name="app_name">Wireless Update</string>.
