Introduction

This guide is for the removal of the daughterboard. The daughterboard contains the Micro USB port.

  • Power down your device.

  • Use your plastic opening tool to wedge between the seams around the sides of the device. Pry open each side, one at a time.

  • Do not pry near the USB port at the base of the device as you may crack the rear panel.

I had a heck of a time doing this, spent ten or twenty minutes carefully prying, and I STILL cracked the case. At least on mine, the case was held in VERY well and required prying pretty much everywhere before it would let go. The tools I bought from iFixit really helped, but still a royal pain to open.

a couple of obscure things that might help in opening:

guitar pick. get a few; they are cheap.

a prying device made for the sign industry: its called"lil' chizler". I have found that this to be the most helpful opening tool.

Flip up on the WHITE part, facing away from the cable. I sort of struggled with this part, but fortunately didn't do any serious damage.

This is the correct way to do it. Flipping up the white part is what you have to do. I tried flipping up the black part and some of it broke off.

I found that I had to flip up on the black part here. I broke a section of the white trying to flip it up.

This comment saved me on this step. Indeed the secret is to flip up the black part of the connector, located opposite the side where the cable inserts.

This is wrong, these comments should be deleted so as to not confuse more people.

Jeff Andrews -

It's possible there's more than one color variation in production on these Nexus 7 ZIF sockets. To complicate matters, it looks like the guide's original author/photographer may have simply yanked the ribbon cable out without opening the socket, so there's very little visual clue here as to which is the right section to flip up. Based on these photos, I'd say Hannah's tip is probably correct—you want to flip up the thinner portion of the socket, opposite the cable (regardless of its color scheme). If someone who has successfully completed this step could supply a better photo, that would be super helpful!

Jeff Suovanen -

I revised the text so there's no long any mention of the coloration of the socket.

I believe I broke the ZIF attached to the mobo at this step; is there any other way to reconnect it during reassembly or will I require a new mobo?

This was my first time with this kind of ZIF socket and found these instructions/pictures ambiguous. In hindsight I see what was being described (actually used the replacement daughterboard as my guide). May I suggest this phrasing:

The ZIF clamp hinges on the side opposite of where the cable in inserted. Using the flat end of a spudger or your fingernail, flip the thin portion of the connector up and away from the insertion side of the connector.

charles fineman - Reply

Correction of Charles' Oct comment: The ZIF clamp hinges on the same side as the cable is inserted, the side towards the battery. The cable runs over the battery and into the thick connector, with contacts both on the side closest to the battery and on the side away from the battery. Beyond the contacts on the side away from the battery is the thin part to be lifted. Using the flat end of a spudger or your fingernail, flip the thin portion of the connector up and towards the insertion side of the connector. You can leverage gently against the big copper-covered area on the side away from the battery, in lifting the thin (white in the current picture) part of the connector.

some better macro photos of the zif socket would help a lot, in closed and open states

For anyone like me who has only experience with metal connectors similar to iPhones, this is a "switch-on/switch-off" connector.

The cable doesn't pop out by itself, you have to pull it out yourself.

Light to moderate pressure required.

Please make the pictures clearer as Iain Lennon said. I too was a fool to not read the comments and broke the connector off of the motherboard.

I couldn't get a grasp on the sticker enough to peel it off, so just punched through it with the screwdriver. I don't know the point of removing the sticker, since the warranty is voided anyway by either time or the mere act of disassembly.

How come the battery is still in place in the picture? I couldn't get the battery out until I'd removed another 3 screws...1 on the daughterboard (step 11) and 2 on the motherboard (step 16).

Mark Birbeck - Reply

Both hidden screws were holding the battery tray in place. I was not able to remove the battery as described in step 9 before removing the screw from this step

Is there a reason you suggested removing the screws at this point? I found it to be more of a hassle having the board moving around as I did the next several disconnects. Unless there's a good reason, I would suggest leaving the screws in until the foam and the connectors have been detached.

According to these repair stories, it worked fine without any mentions of a need to calibrate: Nexus 7 (2nd Gen Wi-Fi) LCD Board

Great guide, easy to follow, the only input I would add is that stating which direction the zif connectors open would be helpful for newbies like me :)

Hello i have a problem with a spudger in the daughter board, i crashed one of them will replacing the screen, i need to know how to fix it or the best place to buy a used daughter board

Hady Allam - Reply

My nexus 7 2013 wifi is charging fine with the existing board, but when I connect it to PC, it doesn't open the USB connection. Now, do I get the replacement or is this is a software bug?

manohar.m - Reply

Try a different USB cable.

I posted this in the Q/A section but I thought I'd post here.

I purchased a replacement USB board on Amazon provided by ifixit for my Nexus 7 (2nd Gen) tablet. The installation was easy, but after turning on my tablet the left half of the screen would not respond to touches. Charges fine though (which is why I bought the part). I let the tablet charge then I swapped the old part back in. Viola! Screen works fine. Is there another step I need to perform with this new part or should I send it back for replacement?

Answer your question
