Mainboard for phone is the most expensive part of mobile phone. I dont know if buying that would be smart buy. You will be better off buying completely new phone, I think it will be cheaper.

Searching S3 16gb mainboard

Both microphones on my i9300 are failing so I am looking for a used but fully functional 16gb mainboard to revive it. It must be one that operates wit European SIM cards. If anyone has a somewhat broken phone with an in tact mainboard pls send me a pm.
Cheers
P.S. Hope this inquiry is ok .. in the forum rules I only saw that selling is prohibited.

[Q] Where is the ESN/IMEI stored on the S4?

Hello all!
So, my S4 has been having some problems lately. I'm pretty sure my motherboard is bad, it's been heating up a lot and randomly telling me I have no SIM card, or that my SD card has been unmounted unexpectedly.
So, I was planning on buying an S4 on eBay or Craigslist that has a broken screen/digitizer, because people sell them cheap and I'll be able to swap the motherboard and SIM/SD card slots from it to my current S4.
My only question - if I buy one with a bad ESN, is that stored on the motherboard? Will it affect my current S4 in any negative ways if I swap the motherboard in?
Thanks!
Are you sure it isn't just a module fault? (The sd and sim tray are in the same cheap module)

IMEI is stored in the EFS Folder linked with the board..
Press Thanks if I helped

I'm not exactly sure, it could be now that you mention it. Where would I buy a new module at?
Oh, I forgot to mention, occasionally the phone also sits at the AT&T logo when booting without continuing, and I have to hold down the power button and restart it to get it to boot.
I think there esn will go with the motherboard, but not 100% sure about that.

[Q] Question with a note 4 demo unit

Hi all of you, i´m thinking to buy a note 4 demo unit i know that it can´t be used like a normal note 4 but here´s a but, i´m also thinking to buy a note 4 normal mother board and my question is, if I can replace de normal motherboard in the demo unit and have a full phone working, I want to do this because is more cheap to me if I buy separately and make the phone working, sorry if the post don´t go here, I will be really really thanksfull is you can help me thanks in advance.

Not sure about the others. But the phone seems like not able to get opened up as easy as unscrewing the screw. Probably will leave some scratches or damage to the digitizer etc. Is the price differ that much?
PS: What about IMEI number?? If you are buying demo unit I don't think you will have any valid IMEI from the demo phone.

He could just use one from an old phone (or maybe his carrier doesn't care about phones without IMEI-numbers).

If you have the demo units that had been used during launch then your going to need more then a Mobo. The screens don't actually work so you'll need one of those. Also a battery. Then the Mobo. Working Spen, because the demo units don't actually work. Then you need to get the equipment to flash a IMEI if the Mobo doesn't have one. Just at the price of Mobo replacements your better off buying a real Note 4 straight up.
ok I want to do that because I already did with an S5 I purchase a demo unit then just replaced the motherboard with another that I have, and now I have a fully functional galasy S5, but I don´t know if it is the same with a note 4 by the way the demo unit of the galaxy S5 is the g900x model and use it with a g900h motherboard

this is really old and all, but:
i opened a note 4 live demo unit last week:
the antenna cables between the mainboard and the bottom/usb PCB are missing including the connectors on the boards(s),
so it would appear that you at least need to add those cables, and either solder the connectors on the bottom pcb (or replace the whole bottom pcb, which is likely easier).
and beyond that, i cannot tell if the actual antennas are maybe missing too.
(and maybe one of the two cables is for wifi, which could explain that wifi is rather weak on my note4)
I believe that demo units are actually fully functional units of the retail product. The only difference is that the OS has been customized so it contain additional retail demo bloatware.
i own three note4 demo units (off ebay) and used them for years, with wifi tethering to a low-end phone for internet.
here is a picture of a disassembled note4 demo unit (right/top) compared to a regular (gsm) unit (bottom/left).

please observe the missing cables and unpopulated pcb connectors.
i dont't know about the other radio hardware.
i've had an offer from somebody who can supposedly turn a demo unit into a functional phone with a software fix, but the missing cable speaks against that.
otherwise the main difference is that demo units have the "samsung retail mode" app installed, which does all kinds of annoying things, and blocks any removal of itself through regular means (unless you know it's password), but getting rid of it is rather trivial, because the bootloader of the demo units (that i had) is not locked. you can just flash a new rom (AND wipe userdata)... or even just a custom recovery, and delete the retail-mode app from the system through the recovery.
but even then, no cellular radio.
and no gps(!), supposedly because gps is handled by the same chip.

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.

Looking for a good motherboard and don’t know which is the best. Don’t worry. Here we are introducing the best motherboard for Ryzen 7 3700X. It is a really impressive launch from AMD and its third Generation of Ryzen chips.
With it, you’re getting 8-cores and 16-threads, with a boost clock speed of 4.4GHz. With some other unique and fastest chip from the Ryzen 3000 series, we can’t wait to see what the future holds for AMD processors.
