I am looking for a used jamin motherboard (a working board) if anyone has one for sell. Mine is completely dead. Maybe some one here has a jamin with a broke screen and wants to sell the motherboard. or a board with something minor wrong but that still works.
Have a look in e-bay... there's lot's of spare parts for our prophet's there... Be careful with what you buy...
Yes. I have been looking on ebay with no luck yet.
Hey guys my phone won't recognize the sim card anymore so I need a new slot. Does anyone know any websites that carry it in the us for the price of Ebay? I want it for cheap, but can't wait two to three weeks to get it. Also, is it possible to purchase just the center housing for the kaiser, the part between the faceplates which has the power and camera buttons on it? I don't want to have to buy a full housing if I don't have to since I already replaced the faceplates. If anyone has any info lmk and list the website. Thanks.
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.
Hi i need to buy charge board which is at bottom of phone but i couldnt decide which one i must buy https://s.click.aliexpress.com/e/bB3FUtUU this one is looking like good but i dont know is it fake or original. Maybe there is not an original one but i dont want to break my phone. What would you suggest?
Looks good to me - normally you have to solder on the vibrator unit taking it from your old board if it's not original.
Bought a copy for my idol 3 from ali and it worked fine go for it.

Thanks i have bought it
Hello, I have an s8 sm-g950u that has a problem reading SIM and sd card. I have been researching for a fix but have about come to the conclusion I will need a new mother board. My main question is.. about which to choose. I am in the US and know the nootloader of this phone can't be unlocked. If I were to purchase a motherboard of an unlockable model would it work in this phone? What things would I have to be concerned With? Would it change.my imei and other identification numbers... would there be any other things needed to be done to make it work in my she'll? Would I have to replace any other parts? Knowing the motherboard would be shipped from Ali express, for around 100 bux, it would be used. Should I be concerned with That? Which would be the best motherboard to choose? The g950f I presume? Any and all advise would be excellent. Thank you xda
If it's like the Galaxy S7, you'll also need the G950F daughterboard that has the USB port on it. Also, I've read that the G950F uses Samsung camera modules and the G950U uses Sony camera modules, so your cameras may not work after the swap.
It might be easier just to find a G950F with a broken screen to buy.
Thank you for that info. I was not aware of either of those tips. I am hoping this thread gets bumped a bit with this reply. I am hoping for just a bit more info if possible.. Or even opinions on a new model that would be comparable to the s8.. maybe wider.. I have been reading on phones for days.. I had no idea there were so many to choose. Perhaps a Chinese variant with equal to better specs
