iPad Mini touch replacement went really really bad.

I changed an iPad mini touchscreen, not first time doing this.

Well the thing is that everything went to s#!t.

My standby wake button doesn't work.

My touchscreen stopped working. i even tested another touchscreen with the little connector board already soldered and didnt worked either. Then i tested both touchscreens and worked properly on a different iPad Mini.

The battery is at 78% and im getting the full charged icon.

It is restarting itself every 5 to 10 minutes.

I was able to perform a restore via itunes, but the issues persists.

I disconnect and reconnected the battery, the issue persists.

Any help, please!
