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

hmmm What i know so its possible you just need to change the motherboard with IMEI .

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).
imgur.com/a/A1WKlJK
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.

I have been offered to buy a HTC Touch, but I am not shure if it's original HTC. Do you know anything if its exists a replica of this phone? I will post here some pictures of this unit. Please tell me if, it's an original HTC, so I can decide to buy it or not. Many thanks ahead!
It may be fake - I can't see external antenna connector above camera.
fake
yes its seems to be fake touch there our many fakes out there from china honkong you have companies that almost make any htc phone a copy of stick to the real thing

no HTC logo on front or back
made in china
i guess it's fake
It's probably an OEM one.
I believe they are manufactured by HTC themselves but are branded as a Dopod S1, i have one (though mine has got HTC logos on it) and it works exactly the same as a branded HTC touch. It still has touchflo and wifi and everything is exactly the same it is just a fraction of the price They are awesome value in my opinion, i paid $296 AUD for mine.
Not seeing an HTC logo, or the internal antenna attachment both seem fishy to me, same goes for the little big thats beside the CE logo on the body of the phone as my Touch doesn't have that.
Usually the failsafe way to check if its fake or not is to see if you can get the phone into bootloader.
maybe
maybe they just changed the external case (probably it was scratched) with a cheap chinese one?

Call HTC and verify the S/N and IMEI shown in the pictures is genuine.
Ahh one of the China replica's
1st: no antenna connector
2nd: You can see the green color from the PCB beneath the battery
fake! 100% sure!
Thank you all for hellping me solve my doubts! Finally I decided to not to buy this phone. Anyway his price was $200 and was brand new. When I told him that is NOT an ORIGINAL HTC, he didn't wanted to convince me MAny thanks again for helping me!
less than $100 in Shenzhen, China
you can buy this replica on the street.
I must say it is a very good replica, and it works, but it is not the same....
try entering bootloader... impossible... there's not bootloader menu, you can enter a kind of bootloader menu for SD only, pressing volume up and reset at the same time... I think it runs windows CE.
Good you didnot buy it !00% fake even the box is very different from original htc one
Hello,
I have recently bricked my nexus 7 3G trying to update to 4.3. It is in APX mode with no easy solution.
I was thinking about buying in ebay a nexus 7 wifi 16GB motherboard. The idea is to change the nexus 7 3G motherboard for the this one.
I have doubts if the wifi motherboard will fit in the chassis and if all the rest components are the same so all wires and connections and battery will work.
Does anyone have any advice?
Thanks!
My advice is to add those 30$ 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!

No idea then if its a store demo unit .
But see google multiple posts on people trying to make demo units work .
Does anyone know if Samsung's Note 4 motherboard replacements actually have a proper EMMC chip? Or are they simply giving you another defective motherboard with a short warranty?
I'm asking because Samsung in Canada wants $390 to replace the motherboard. Even the service staff guy rudely recommended against it. It only comes with a three month warranty.
So, I'm inferring they don't actually change the motherboard. They most likely just give you another Note 4 and hope it doesn't go bad in three months.
Also - Any suggestion of a robust android phone would be much appreciated. I seems like Samsung is the Ford of phones.
$390 seems excessive. In EU a used Note 4 is ~$150. Note 4 with a broken screen ~$90.
I plan to do the motherboard swap myself and would suggest you check out https://www.youtube.com/watch?v=OUDgGaFcCNY&t=287s and decide if you want to try it yourself.

Yes, $390 is excessive, but that's Canada for you..
If you're planning to do a motherboard swap, how will know if the new board has a good emmc chip? Are you buying the board directly from Samsung?

I'm planning to buy a used Note 4 with a broken screen. Possibly even N910C. Now, I cant know for sure the state of the eMMC chip, but it will be better than mine, that is dead
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.
