Very great guide on the teardown for swapping the motherboard. I have 2 questions if you wouldn't mind clearing up.
1. When you remove the back cover from the screen, is it glued into place or does it use small snaps to hold onto the device? How hard is it to reattach the back cover?
2. After buying a new motherboard for installation will I need to flash it with bios/firmware/OS to get it working or will it come as a ready-to-go motherboard?
Thanks for your help!
Great guide, excellent pictures, helped me resurrect my Nexus stuck on the Google screen. Thank you!
However, it should be emphasized that steps 10-15 are completely unnecessary and should be skipped if you are only looking to replace the motherboard.
Agree on skipping steps 10-15 for motherboard replacement. The daughterboard was not in the way at all.
Great guide and good instructions. I was able to swap out a faulty motherboard without any problems.
Two things I found that might need some addition/update on the instructions;
1) I found a #00 Phillips easier to use than the recommended #0 Phillips
2) You should probably add one more step to explain how the camera is attached with a ZIP socket to the underside of the motherboard. That would help in reconstructing the tablet in case, like me, your camera does not come up with the motherboard.
Great work and thanks for the help!
Hello,
i would like to ask some help. I did everything exactly as you mentioned upper, however my screen is not able to handle my touch. Do you have any opinion what should be the problem?
