A

I saw same filename with same content:

3242456a412a9598cff06b52efd7c66a13f8a750

So I copied the other files from BP without visible success..

B

I saw logfiles inside logfiles :D

1 earlier attempt was to replace file inside TPK....

appcessoryservices.xml

Without success... replaced with BP file...

ECG have other channel...

<serviceChannel
id="99[B]2[/B]"

Instead 991 from BP...
