How to install fieldtest?

I am trying to find a way of installing FieldTest.apk on my HTC Wildfire S. Trying to install right away yields:

[evad@v3350 Downloads]$ adb install FieldTest.apk
961开发者_Python百科 KB/s (127564 bytes in 0.129s)
pkg: /data/local/tmp/FieldTest.apk
Failure [INSTALL_FAILED_SHARED_USER_INCOMPATIBLE]

So I did a bit of googling and discovered apktool which I've used to decode apk and remove android:sharedUserId="android.uid.phone" bit from AndroidManifest.xml, but then I've got:

[evad@v3350 Downloads]$ adb install FieldTest.apk
1247 KB/s (77631 bytes in 0.060s)
pkg: /data/local/tmp/FieldTest.apk
Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES]

Did you build your app with JDK7? I met simmilar situation with JDK7. When I have switched it to JDK6, it was resolved.
