Hello.
I own a S7 and my phone was in official service and my motherboard was changed (along with the camera, speakers).
I asked the guy at the service why i have the same IMEI if my motherboard was changed and they say that it was rewritten to the new motherboard.
Is that possible?
Of course it is. As a matter of fact, you could buy s7 mainboard with blank IMEI and write your own if you had appropriate tools for that
Yep. It's written by a special piece of kit called a Service Box. Expensive little things...

My device recently survived quite the impact, the screen got shattered, top right edge got deformed a little and then the ON/screenlock button stopped working the next day, but otherwise the phone was fully functional. So I sent it back to LG for repairs and the next week I get it back in the same condition, with a note saying it's not repairable/board cracked. I called them up, and got an image of the motherboard showing no cracks whatsoever, yet they still didn't want to re evaluate their conclusion when I created a new RA. When I got the phone back the battery was dead and even though I charge it I cant turn it on, until the button is replaced. LG suggested I contact Google for repairs, Google said I should contact LG. These people are helpless, they don't know anything. I could do the repairs myself, but I can find all the required parts online. Can I get some suggestions on my next step?
"Thank you for contacting LG Customer Service.
We are sorry to hear about the problem you are experiencing with your LG device, however, your phone has already been inspected by our technitians at our repair facility and, unfortunately it has been determined that it is not repairable.
We recommend you contact your carrier for any replacement possibnility."
not much to do but to repair it yourself if you want then, or maybe look for one on swappa?
for parts http://www.etradesupply.com/lg/android-models/lg-nexus-5.html or ebay
btw it looks like you need this http://www.etradesupply.com/lg-nexus-5-lcd-screen-and-digitizer-assembly-with-frame.html
Screen and battery are no problem, i could replace them any day. The power button (blue circle in the pic) doesn't work, if that's the issue, I would need to replace it, but I can't find any replacements. I actually spotted a tiny crack on the board (red circles). Ugh. Would i have to replace the whole thing?
Maybe its best to sell it for parts and buy a new one, that phone looks allmost like a total-loss. Maybe some of the internals are damaged also and total repair would be too expensive.

I have issues with the power button too because mine get stuck lot of times and it's verry annoying. I've contacted LG service center but they said that because it is soldered to the mainboard the only option to repair is to change to mainboard. I'm shocked . I haven't got warranty here because I bought it on Play Store in Canada and I'm living in Europe.
Btw I've started to research this issue and the parts and it seems these switches are the same as Samsung uses in their new galaxy phones. There are tons of pieces on ebay from it. But changing it is hard. You need a good heat gun which is able to point the heat to a small area and you have to heat the switch only. If you heat any other parts, then you phone is dead...

But I'm not hundred percent sure that these are good switches for us, they just look the same :/

I've done the repair on a Galaxy S3 using the part from Ebay. Let me tell you now that it is a pain in the ass if you don't have good micro-soldering skills. I don't, lol, but my father does and he got it done for me. Be warned, you will mess up the board if you don't know what you're doing, but it can be done. Maybe find someone local who can do the swap for you.
buy a new one, cause this one is a dissaster! keep it for repairing parts...
I'm currently trying to replace the motherboard on my galaxy S7, AT&T (SM-G930A). Since I'm taking the entire mobo out, does that at all allow me to put a motherboard from a different cell carrier (ex. verizon, t-mobile, unlocked, etc.) inside it? If not, what's preventing it?
It should not be any problem to do that right? I would just make sure that the new motherboard is the same model as the original.
I've done this type of repairs on galaxy s4 and almost every iPhone except 7 and it was never any problems.
How did it go, did you manage to change motherboard? And is it working?
I haven't replaced it yet because I want to make sure that I can do it in the first place. The thing with the samsung mobo's is that for different carriers there are slightly different models - for example, Factory Unlocked is SM-G930V, T mobile is SM-G930T, etc. I want to be able to use a same motherboard but different variant because I'm not on AT&T so I wouldn't be able to use it as my phone. In your repairs, did you ever notice if you changed out a motherboard for a variant from a different carrier?
Hi All,
I was changing a broken lcd for a P20 and ended up 'breaking' the part circled in the photo. Is there a way to replace it or do i need to replace the entire main board? Where would i find the main board if i need to completely replace it?
You cannot replace a "mainboard" yourself unless you have a donor device to get one from... Maybe buy one with a broken screen, but without being able to confirm functionality you are just rolling the dice.
Manufacturers don't sell these as replaceable items, the mainboard is what holds the identity of the device (serial number, IMEI's, etc) so you must send it in to them, or have an authorized repair center, repair it.
Anyone know of vendors I can contact to get an estimate/quote to repair my Joying Android head unit?
My credit card company has insurance which "extends" the original manufacturer's warranty, but they are asking for a formal "repair" estimate; they won't accept evidence of the cost of replacing the entire unit.
It's a pretty niche device so wondering if anyone knows vendors who will perform Joying electronic/board repair? Location doesn't matter as it can be shipped.
I already tried contacting Joying themselves, and awaiting a response, but not sure that they even offer this type of service outside of warranty.
Thanks!
What's wrong with it? What are the symptoms?
In any case, try one of those cell phone repair shops/chains. I remember quite a while ago that they repaired game consoles too.
It sometimes powers off then back on, and I think the bluetooth module and SIM card module need replacing.
I reached out to a couple of those types of shops locally but I think this Joying unit is pretty niche so they don't service it.
Is it possible it's a power supply issue? Were the wires crimped together or soldered together? Maybe take it out and hook it up to a power supply on your kitchen table or desk for a while to see if it happens again.
