N7 Repair - what electronics are IN the bezel? - Nexus 7 (2013) Q&A

So.... I had a VERY tough week at work and was exhausted, stumbling getting out of my car... and dropped my Nexus 7 (LTE!!!)... Screen was still fully visible but non-responsive and glass extremely shattered over the entire surface.
Like an IDIOT, I believed some of the tips and only ordered the glass/digitizer and not the LCD. Well there's $50 down the tube as you CANNOT separate them without destroying the LCD (do not believe anyone who says otherwise)..
So.... Hairdryer would not soften the glue at all so I had to buy a heat gun. On the lowest setting (for safety) it barely softened the glue and required a LOT of persuasion to get the glass loose. The LCD was (as pointed out by those who have actually done this) destroyed in the process... OK, now $100 for the full glass/LCD combo.
However, I have ONE huge concern. During the process, the bezel on the top got overheated and the plastic is damaged. The bezel still snaps securely to the back. However, I noticed there is a small circuit board *inside* the bezel with three metal contacts. What is that? Is it possible that's damaged? The plastic around it shows definite signs of heat damage. Since you CANNOT order a replacement bezel for a N7 2013, and since this is an LTE device, I'm pretty committed to fixing it still. But I'm nervous about ordering parts with the damaged bezel if there are irreplaceable electronics that have been damaged inside the bezel...
So... my question: What is that circuit board that is molded inside the bezel with the metal contacts? What are the odds it was destroyed?
(Posting photos in a few from the phone)

Here are the pictures.
In one side you can see the contacts. The other side the circuit board in question is visible in a small opening.

EDIT: I looked at the part from iFixit, and the bezel is quite different on the LTE model from the Wifi model. It appears that this is the wifi antenna ... the bottom of my bezel has another similar one which is probably part of the LTE antenna. ... so the question is, what are the chances the heating damaged the wifi antenna... not sure what I think about a 4G only tablet...

UPDATE
Okay... I figured out the wifi antenna (and LTE 4g antenna at bottom?) are actually stickers... it appears they're not damaged as best I can tell. Hope so. The bezel is warped noticeably at one end, but it still snaps into the back side of the case just fine, and the circuit bords fit. So hopefully... *crosses fingers*... it is still repairable.
Honestly, at this point though, I wish more people who had actually DONE the repair would have suggested that it is NOT something to be done by end users. Reassurances that it's "easy if you follow the directions" are highly misguided. At this point I would have paid ASUS for a repair and come out ahead, once you count the resale value of a device that now has a visibly damaged bezel if I even get it working again. I've never had a problem repairing devices in the past, but this one is not as easy as so many "guides" make it sound.
I should have realized sooner that most of those who said it is easy are also in the business of selling glass/digitizers (USELESS!!!) and LCD/Glass/Digitizer combos.

quite similar experience to what i had trying to repair my old n7 glass, only did i order the glass/lcd combo from the beginning. cracked it while trying to fit it in the warped bezel tho.

Yeah, breaking glass due to the warped bezel is what worries me. Unfortunately the LTE bezel appears to be different than the WiFi, so buying a cheaper one and swapping the bezel doesn't appear to be an option either.

Replacement Ribbon ANTENNA Flex Cable for HTC TP2?

Here's the story, bought a used HTC Touch Pro 2 for cheap and found out that the idiot before me glued the battery cover to the phone!
Apparently when they removed the door, likely to remove their sim card, they damaged a flex cable which i believe is an external adhesive backed antenna. See picture below for broken flex cable antenna.

Now I've taken apart the housing and the antenna just adheres to the housing and has contacts that touch the main board.
What I want to know is where can I buy JUST the antenna ribbon??
Thanks!
And this is why I buy stuff brand new...
eBay could help you. Are you planning on fixing it yourself?
I've looked on Ebay and haven't seen this particular ribbon cable.
Ebay does offer the FULL housing for the TP2 but it is not the T-Mobile version housing.
The full housing they offer does come with the ribbon cables preinstalled but have yet to see anybody convert from the T-Mobile TP2 to the Euro/North American TP2 housing.
Yet, I don't think it would be difficult to convert over but you will need a new digitizer as the faceplates are different as well as the front keypad ribbon cables but the costs are not within reason.
Called HTC today to see an estimate on the repair. They told me from $100-$309 USD.
seriously??..
anyways..apparently my phone is also missing the sticker containing the IMEI and Serial Number..because of this, HTC will not repair my phone.
what to do...what to do..
also contacted www.cellulardr.com and they also required the S/N to order the part.
Anybody kind enough to share their T-Mobile TP2 S/N with me to get the part number? Or even better, contact cellulardr.com and get a part number for me?
THANKS!
If the ESN/IMEI is missing and it was "cheap"... sounds like stolen goods.
Sorry to say, but you got what you paid for... caveat emptor.
The minimum $100 you can spend on getting the part, plus whatever you spent on the phone and your time could have gone towards a legitimate and in excellent shape device. I don't think anybody here is foolish enough to share their S/N with you.
this can easily be fixed and very cheap.
I have an htc magic and replaced the housing cover, and if you remove the antennas(in this case we have to remove de bluetooth and gps antenna to fit on the new cover 'chassi'), but those antennas will get trashed if you remove them, those antennas are just a sticker with some thin metal between a bi-adhesive tape and a paper tape.. a three layer thing with metal in the middle. First I got pissed... why these antennas aren't provided with the housings, or why I can find who sells them... I scratch my head and I thought.. why I don't make the god damn antennas? And I just did, how?
You'll need three things:
- a piece of aluminium foil, that it's used to wrap sandwiches.
- thin Bi-adhesive tape, there are some with 4 or 5cm (2inches), that's what I used.
- Paper adhesive tape. (i used the leftovers of printing cd labels)
With that, u just put the bi-adhesive tape over one side of the aluminium foil (i put it over the polished side of the foil), on the other side, u stick the paper tape, but leave a piece uncovered to make contact with those things that sticks out of the board, then just cut it with scissors with the right shape for the chassi and stick it on it.
I must say that the result with me was brilliant, I get gps signal very fast, even faster than with the original antennas, and with bluetooth, no problem. The wi-fi and network on the htc magic shares the same antenna and it's made of the same material, if needed I'd do the same.
Hope you understand me, my english ain't perfect.
regards
I've unfortunately done exactly what you've said and I removed the GPS antenna tape not realising it was actually important (d'oh!) and as such my GPS no longer gets any signal.
Thanks for writing above about a replacement antenna that could be made, but can you please tell me where on the motherboard the actual GPS contacts are? Sadly I have absolutely no idea where the tape was, I only know that I removed it!
Thanks!

Creaking w/ battery cover?

Anyone else's battery cover creak when it is pressed below the camera? I find that when I first put the cover on, it's fine, and then after a few hours, the creaking starts to show up. Wondering how normal this is.
I haven't heard anything from mine yet. One thing I used to do a lot on my Nokia N97 to stop that kind of creaking was to *LIGHTLY* bend out the pins that secure the back cover. Be careful not to overbend them or you'll end up shopping for a new back cover. I don't know how much that will help though, because from what I saw when I put my sim card in, was that all the connectors where located on the edges of the cover.

No creaking hear. But then again, I didn't go looking for it
IMO, it's not a problem unless it happens without looking for it. All phones have some creaks if you start pressing on them from all different angles. Especially on parts that snap together.
Interesting. I definitely wasn't looking for the problem. it just happens all the time with normal use, because usually my index finger rests there when I'm on the phone, etc. Good to know it may just be mine though. Battery cover should be easy enough to get replaced.
My colleague pointed this out to me with his SGN, mine does it too. He placed a small adhesive padded sticky just below the cam. As i have a case, it doesnt bother me.
Any idea what he stuck to it exactly? That solutions sounds good enough for me
Not quite sure, will try to find out. It was a bit thick in my opinion though as the case stick out a bit around the lenses. Could probably take a scalpel to it tho to thin out the padding.

Got my nexus yesterday and noticed this. Although its not a big deal, its annoying once you notice it!
Do you guys know if Samsung would send me a new back cover for this or would I have to get the whole phone exchanged?
I have the same problem when I press on the green areas of the image I have a little creaking, but it feels when I press a little hard, but still bothers me because it's a $ 700 phone, I bought my phone on ebay to a Chinese seller, so I think I'll have to find a solution for myself.

I have this problem also. It is even worse with the extended battery cover. I love this phone overall but I am not impressed with the build quality.
Just to confirm, my SGN has exactly same weak spot on the back cover, but I'm fine with that It's still better built than my previous SNS with it's loose plastic frame
Yeah, plus on mine there is at least 2 mm between the battery cover and the phone itself just below the camera. Quite annoying ! I think I will put some ducktape.
Sent from xda appel ( Sorry for my bad english, I'm french)
I find this "creaking" almost being a feature I like to press and tap the back cover while waiting when the phone does something, such as downloads from market and so on... it keeps me occupied
I added a small bit of cotton fabric between the battery cover and the phone and it seems to have solved the problem. I just cut a bit about 1cm by 3cm and placed it below the camera. This way I don't have any sticky mess from tape in my phone and I hardly every open the back. Maybe I will super glue it eventually but it works fine to just wedge it in there for now.

I just solve my problem 2 days ago, I did was disassemble the phone and remove the housing and put it back, Now I have no creaking even in the battery cover, my phone is now like a rock.

[Urgent] flash LED / rigid flex damaged?

Hello everyone.
I have a question for you.
I've send my phone back for warranty because one of the leds stopped working.
Problem occured when my upper flash led became blueish and after a while i couldnt even take pictures with flash because it made photo completely blue.
Eventualy, that led died.
Now i got it back from repair and they wrote down something like that:
"Mechanically damaged phone (bruised), consequently damaged rigid flex.."
So, I am asking what exactly is "damaged" rigid flex? As far as I know, rigid flex is some kind of "tape"-like part of motherboard? Some kind of connector? And if this is true, how the hell could rigid flex be damaged INSIDE OF OUR ALUMINIUM PHONE?? The phone was never disassembled neighter dropped. It has 3 scratches on the back above the battery slot. I got them when i was at the beach and phone slided (not dropped or anything) for about 5cm on the little rocks there, nothing MAJOR really, even the scratches are small. Also that couldnt effect that rigid flex.. And if rigid flex would be damaged, as far as i know, both leds would be gone + camera or some stuff??
Thank you guys for your answers and your time spent reading this
With Love,
miHah
I don't know what that means, it sounds made up. I just replaced my upper board with the LEDs on it icant see it getting damaged any way other than a bad led. The board costs $50 on eBay. Did they charge you? I never send back for warranty they always try to back charge. You can always find the parts on eBay. As you can see they are solders to the board. The black cable connector beside them is the power. Maybe that was damaged?

No they did not charge me anything, they just refused to repair that.
I demanded photos of "damaged" things because I am curious if they even opened the thing. I think they didn't as I am looking at those pics.
Those LEDS and the mainboard looks completely different from yours. Or is it only me?
Also, they provided me the "bruised-phone" photo (reason why they refuse to repair it under warranty). Wanna see?
Thank you for your answers!
They are taking you for a ride, the "Flashlight"/LED cable is under that mylar tape that they didnt even remove. I would complain make them tell you exactly what was damaged. you can see visible damage to the LED.
My phone is a telus the bigger black rubber thing is a noise cancelling mic to the left of the leds you can see the 4 solder points just above your leds.
where the wire i soldered to the board was where the gps antenna connectors was and they are right of the leds on your pic. They are the same board just mine is out on my desk yours was still in the phone.
Those boards are different. Make sure if you have the European DHD that you don't purchase a board for the Telus Desire HD or Inspire.
Is that discolorization on the board from it getting wet or from the LED exploding? Wow, can't believe they refused to repair your phone because of some exterior wear and tear.
It was never exposed to water or steam or anything. The closest incident it could get wet was once when I took a shower it was in my bathroom while there was a little steam on the high level of the room but that couldn't have had any effect on anything.
LED Exploding? How could this happen?

These boards are almost identical. The only difference is the noise cancelling Mic. I have a telus desire hd and replaced the board with a euro. One. It worked perfect.
Just watch the teardown video and replace it your self. It takes awhile, but not real hard to do. Took me about 1/2 hour.

Camera glass replacement?

I broke the glass behind the bezel and in front of my camera. I've checked everywhere I can think of and can't find it. Does anyone know where I can find one?
I thought the glass was part of thw bezel?
Nope. If it was, all the ebay stuff would work. Unfortunately, no glass included. One more post and I can finally start helping in the dev section! By way of rigorously testing the roms and reporting every little issue

I tried googling for it but could only find the bezel. Your best bet would probably be to find broken inc phone cheap (good glass of course), and take the glass out of it and put it in yours. You could probably get it direct from htc, but who knows what they would charge you.
Back in August the entire glass element AND the bezel wouldn't stay on the phone, so I had to replace the entire back housing just for the lens.

Then a couple months after that, I dropped it from about 3 feet while sitting on a chair and cracked the lens. Been like that since, but it doesn't affect the photos as far as I can tell. Unless the sunlight is hitting it at just the right angle.
Also replaced the speaker 3 times, until I found out I can just use a magnet to pull metal shavings off of it
And yet, I've never broken the glass. It's been dropped off the top of my truck (long way down), dropped in a pool w/100% submersion, and fell out of my pocket while on an ATV and run over. Soft ground saved it there as it was able to sink in. Never had a case either.

do you have a place called "tap plastics" in your town? they can make you an acrylic one that will work. http://www.tapplastics.com/ they just need the dims and thinkness of the glass used to be. or take it in to them. shouldnt cost to much.

The same thing happened to my camera lens too but i cant tell any difference when taking photos.

Broke back camera glass cover, after replacement camera won't focus UPDATE: fixed!

My issue is the title. The back glass (or whatever material) cover over the camera broke somehow (I really dont know how, I took it out of my pocket and it was broken!) while I was on vacation last week. I just now received a replacement of the entire plastic piece and glass cover that you see when removing the battery cover. It fit perfectly, and looks quite nice, however my camera is now unable to focus. I actually noticed this same issue after only removing the plastic cover and having the camera bare (without the glass cover at all). I have cleaned the lens fairly well with a nice cloth (one that I got with my eyeglasses and I have only ever used on my eyeglasses, that also stays away in a little sleeve), but that doesn't seem to have made any difference.
I found a few threads on this issue searching around. Some of which people said that the cover was required for focusing to work, and some that said it still didn't work after replacment. It appears I am suffering from the latter. Unfortunately, there were no solutions posted for that further problem besides "return it to samsung".
My phone is well out of warranty, and I would rather just try and repair it myself or just sell it off for parts and get a new phone.
Anyway, I was wondering if anyone here had an opinion as to why this issue may be occurring, and if anyone had experience fixing or at least ideas on what may be done to solve this issue. My random theory was that some piece of the broken glass fell into the lens module and has somehow restricted functionality of the lens, thus resulting in the failure to focus. In this case, it seems my best option is to drop $30 for a replacement camera module and perform that replacement. I was looking to see if anyone had any success stories regarding that job, or perhaps a simpler route I may be able to take.
Thanks in advance!
This is of interest to me also. I ordered a replacement lens cover from Ebay and it came in; what I have is the silver and black "frame" and a black circle with what appears to be the actual lens cover glass. For one thing, if it's going to ruin focus I won't do this. For another, the black circle appears to fit on the outside of the silver and black "frame" and doesn't appear to stick to it in any way. Has anyone performed this repair and have any suggestions?
The replacement I ordered came in the same way you mentioned, the plastic frame and then actual glass cover, except in mine the glass cover has an adhesive strip pre-applied in a ring. If yours doesn't, I suppose you should use something like a thin amount of glue or double sided tape.
I actually tested my camera first without the frame and cover at all before I even got the replacement (I simply removed the broken one as it wasn't providing any protection anyway), and found that at that time I wasn't able to focus. I put some blue masking tape over the lens to shield it until the replacement part arrived.
I actually found a replacement camera module on ebay for only about $15, so I've ordered that and will attempt the repair when it arrives. I'll update this thread with the result of that effort.
Back with an update.
I received the replacement camera module today. After following a simple guide I googled for, I managed to replace it. (fairly painless process really...)
As for the result....

Great success! The overall repair cost was only ~$20. ($5 for glass cover, $15 for camera module) If anyone else finds this thread, just ensure you get the "i747" supported part!
