I have checked the ROM details and found this in the target-file-package:

<root>
<buildnumber>P2 Lite_Blackview_20170622_20170622-1454</buildnumber>
<language>en-US</language>
<oem>miracletek6753_7.0</oem>
<operator>other</operator>
<product>P2 Lite</product>
<publishtime>20170622160419</publishtime>
<versionname>P2 Lite_Blackview_20170622_20170622-1454</versionname>
<key>build/target/product/security/testkey</key>
</root>

As you can see it uses the testkey and not the releasekey

Can you please provide a ROM which is signed with the releasekey instead?

Thanks for your feedback. I will report that so that the next version should be signed correct.
