Ok so, repaired like 20 Xcover phones this far and first time i encountered this issue, the Phone starts up just fine When the digitizer is not connected to the lcd But When i inserts the digitizer into the lcd the Phone wont boot at all, ive tried two different digitizers now. I figured there must be some short cirkuit in the connector But the connector is working just fine, anyone knows why this problem occures?

I found the fix, it is a different touchscreen for the two models.
