N7 Motherboard

Hi!
My Nexus 7 (32GB, 3G) likes swimming but motherboard do not.
So, my motherboard broke down. Asus service want almost 400$ for repairing it (New N7).
Can I buy 32GB, 3G motherboard for N7?

you could probably buy a n7 off ebay with a broken screen for less and swap your screen across for less than a motherboard will cost

[Q] LG Google Nexus 4 Motherboard Replacement

Hi everyone,
As in my title you can understand, i have a nexus 4 with broken motherboard.
My phone is purchased from U.S., but i'm living in Turkey. So i can't send my phone back to U.S. to change it to a new one.
I have another option, to buy oem motherboard and replace it self in my home.
So i found the motherboard BUT, there are T-MOBILE NEXUS 4. But my nexus from Google.
My question is, will it work, if i buy this motherboard and replace it with my broken motherboard?

There is no difference between the nexus 4 from tmobile or Google.

problem with micro sim
Very interesting discussion.
Maybe i have to do your same task, because my n4 don't read anymore micro sim
Do you think could be a sw problem or could be an hw problem and i have to change logic board? If yes could you send me where to buy it?
thx verymuch
PS: do you think is possible that UMIDITY (and not WATER( could broke my phone in this manner? (i have to change also battery and connector charge to usb)

I also live in Turkey , you should have shipped it back to where you bought it.
Call Google in these situations.

Nexus 7 Wifi motherboard on a Nexus 7 3G chassis

Hello,
I have recently bricked my nexus 7 3G trying to update to 4.3. It is in APX mode with no easy solution.
I was thinking about buying in ebay a nexus 7 wifi 16GB motherboard. The idea is to change the nexus 7 3G motherboard for the this one.
I have doubts if the wifi motherboard will fit in the chassis and if all the rest components are the same so all wires and connections and battery will work.
Does anyone have any advice?
Thanks!

My advice is to add those 30$ for the 3G version, if you don't know exactly what you're doing, you might screw them up both while swapping motherboards. Also, isn't ROM (or wherever system is) memory soldered onto the motherboard?
Right now first gen N7s are really cheap because everyone is selling them, I'm sure someone on XDA has one to sell, and you can lookup devices whole history based on users posts.
I don't really understand what exactly is you're trying to achieve by swapping MoBos? Have you done this before?
also have you tried this? http://forum.xda-developers.com/showpost.php?p=41860081&postcount=8 you probably have, but still.
Edit:
I had to re-read you post a couple of times to understand exactly what you're after, and here are my thoughts:
1) why buy wifi MoBo, if you can get 3G MoBo? It would make the whole process much simpler.
2) get a cracked screen 3G N7 on ebay, take it's MoBo and put it in you current N7. Throw away your current MoBo.
3) buy a fully working used N7 off ebay (or swappa). Sell your N7 for someone with cracked screen.
4) buy cracked screen N7, replace screen with your current one, sell it, add 100$ and buy new 2nd gen N7
if you do swap mobos, this might come in handy:

good luck!

I want a wifi Mono because it is cheaper. In a quick search in ebay you can find 16gb Mono for around 30$ or less and 3 MoBos are less common and much more expensive, around 130$
Personally 3 is not a must for me now. When I bought the no this was the only model and I didn't care to pay those extra bucks.
But according to how I use the tablet (mostly reading and video at home) I know 16gb with no 3h is ok.
I have the skills to change the mobo so that won't be a problem at all.
What I want to know is that a wifi MoBo would work in 3 chassis.
Thanks

It seems like the 3g and WiFi have different mobos, it may not fit, screw holes are most likely different.

Hi Mach... thanks for answering.
That´s just my fear. But in ebay there some motherboards with the whole chasis. For example, take a look at these two 16GB and this 32GB 3G. The frame are pretty similar. I have compared them from the photos and it looks the screw holes and connectors for battery, screen, speakers blah blah, are in the same location.
And as you can see, the price is totally different!
I wanted to know if there is someone with some experience could know that for sure.
Thanks!

Motherboard question - Help appreciated

Hey guys,
My Nexus 6p no longer receives signal, which is caused by a faulty soldered chip on the motherboard. All the service shops I visited can't fix it, they recommended buying a new motherboard instead. My Nexus 6p is the H1512 (International) model. The question is:
Can I put the motherboard from H1511(NA) to the H1512(International) mode and will it work? Broken USA models are selling cheap and I will pretty much try that, if anyone can give me a hint at the possibility of it working out.
Thank you

Graphics card guys having issues with solder have put their cards in oven at 250 for some length of time (I don't remember) to fix the solder to make a dead card work again.

Sorry to say but I can't see how this could possibly be economical or worth the effort. No reason it would not mechanically connect and function but the question is really: will the NA model work well in your location? A quick google of the bands in Bulgaria vs USA says no. No GSM overlap, No 4G LTE overlap and only one UTMS band on 3G (UTMS 2100). Another risk you take is the MB is already toast on the phone you buy (and the reason it was sold for parts). You really need to find a INTL MB for it to work in your country.

Zte Axon 7 USBC Chagring port pins broken

My kid tried to put micro usb cable into axon7 charging port, which broke the pins of charging port.
Axon 7 is not available in India and no service centers also. Is it possible to replace this charging port with some other phone port.
I went to local mechanic and he tried with OP2 and Pixel phone charging port. But they did not fit.
Any suggestions.

If you can't get a new port, it will need a new mainboard. Possibly better just to replace the phone.

He'll just need the USB PCB like this one ^^. Not a whole new mainboard.

That's good to know
So next question, how old is it? If over a year, maybe have a new battery in it whilst it's apart.

lol if you buy that you'll have to desolder the old one's pins and solder the new. They are SMD and have very little spacing so you'll need experience and a lot of patience to solder it right.
Long story short: Too difficult, simply buy the module that has the port soldered to it and replace it. It is as simple as taking the broken one off and putting the new one, then snapping the connectors in place

I just ordered this yesterday. USB PORT https://www.ebay.com/itm/For-ZTE-Axon-7-A2017-USB-Charger-Charging-Port-Dock-Connector-Flex-Cable-Part/163157945601?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649

Just wondering if you've had success with the boards you ordered and the phone connects to your service provider all right?
Want to ask a follow-up question since I actually had somewhat the same problem (my charging port melted from what I assume to be a faulty cable). I ordered the daughterboard like the one you linked from a Chinese seller, the phone booted up alright but it gets no service, so I'm just wondering if you've had success getting service after you changed the board? I also started my own thread https://forum.xda-developers.com/axon-7/help/a2017u-service-daughterboard-charging-t3841038

Yeah I did, I made sure that I connect the skinny one on the right as well as the main flex cable. The old daughterboard with the destroyed port gets service when I put it back in but the new one I got doesn't. So I was wondering if anyone has successfully used one of those daughterboards and gotten service.. Maybe the daughterboard comes from a Chinese version and is having trouble reading SIM from the American version of the stock ROM?

Check the contacts that touch on the antenna pads of the aluminum backplate. Maybe it's got something to do with that

That's checked as well, no problem there. Works with the old daughterboard but not the new one. I think that I got the Chinese version of the daughterboard and my phone is the American version... Was it the same for you when you changed your daughterboard/phone? Did you get service right away? If you have the US version, where did you get the board?
This is relevant to the OP as well since the replacement bought from Aliexpress most likely comes from an A2017 (Chinese) not A2017G(global) or A2017U (US).
