Hallo,
wo bekomme ich denn ein neues Mainboard her? Ich komme nicht mehr ins recovery und vermute Mainboarddefekt.
Helge -
I followed your instructions to the letter. Got it all put back together, but before affixing the back glass, I powered up the Pixel 3 to make sure all features are working. The touch screen does not work, now, but it did before. Any advice?
Hi Philip,
Does the screen light up? If it doesn’t, I would suggest disconnecting the battery connector and double-checking the display connector to make sure it is properly seated. As I looked into your question, I noticed that the step was missing a disconnection procedure—so thank you! I’ve amended that step.
Hi, I met the same issue as you, the touch didn't work after replacing the mother board. Do you know why? And have you fixed the problem?
Where can I buy the motherboard? Is the 128 GB motherboard different from the 64 GB?
You can find the motherboards on ebay here https://www.ebay.com/sch/i.html?_nkw=goo...

Older devices may require 2 or more minutes with a very hot iOpener. Also note, the photo shows the opener on the FRONT of the phone. The heat needs to be applied to the back of the device!
Rick Johnson -
I just realized that I was trying to pry apart the front of my Pixel 3… and have separated the class from the display. ??♂️ Even though the rest of the directions show the back, it would be nice for the first picture to also show the back, just to be safe.
JR Raith -
Agreed, I’ve done exactly the same and completely broken my display. I probably should’ve paid more attention to the initial steps before diving in but the step could do with a new picture for sure.
Daniel Fryer -
Thanks for the comments! I’ll add a note in the step warning people to make sure to pry the back cover, not the screen.

I prefer my favorite opening method with something like this. Dental floss. So thin it can slide in the gap. A little sawing to get it far enough past the edge to lift and get the first pick in.
John Hoffstetter -
I found another wonderful tool. I used something like medicine packaging which is aluminum foil with plastic. It’s thin and strong enough!
Christie Lin -
I also went for the hairdryer, dental floss, and then the provided picks and this worked. Not easy to get that initial seal broken but once that's done the rest is pretty easy.
James -
I needed 20 nerve wracking minutes with a hairdryer
Amy schneider -
My battery had bulged and opened the case for me!
Warmed it up a bit with hairdryer
Floss helped also.
David Lincer -
I found I wasn't able to get the edges hot enough. I ended up using my heat gun (for shrink tubing) instead.
