Transformation of Galaxy Note 4 LDU to the normal smartphone - Galaxy Note 4 Q&A, Help & Troubleshooting

Hi,
I've got Note 4 Live Demo Unit. I have just upgraded the software, so it displays now, that the version of smartphone is not SM-N910X but SM-N910F. I consider of changing the display and motherboard. And there is the question - what I must look for? Is there specific displays for different types (like N910C, N910V...) or it is univesal?
Will the calling function work after replacing motherboard? Which motherboard is compatible with N910X? Is it N910F? What about IMEI? Or it is much more better to buy another broken phone and replace components from it - there wouldn't be any problem with IMEI?
Thanks very much for your advice.

Note 3 LCD replacement question

Does a Sprint Note 3 screen work on an AT&T/T-Mobile Note 3 ? I have a friend that can replace Sprint Note 3 LCD/Digitizers on broken Sprint Note 3's and was wondering if I could replace a broken/damaged LCD from an AT&T or T-Mobile Note 3 too? TIA
I got my answer via Samsung chat:
info: Please wait for a Samsung Agent to respond.
info: You are now chatting with 'Daisy'. There will be a brief survey at the end of our chat to share feedback on my performance today.
info: Your Issue ID for this chat is LTK1125601008151X
Daisy: Hi, thank you for contacting Samsung Technical Support. How may I help you today?
david: i have a galaxy note 3 with a broken glass.
david: can you tell me if the replacement LCD for a Sprint Note 3 and a T-Mobile Note 3 are the same?
david: or are they different part numbers?
Daisy: I am sorry to know that the device glass is broken.
Daisy: I would like to inform that the LCD for the Sprint Note 3 and a T-Mobile Note 3 are the same.
Daisy: Samsung do repair the device screen and fix it.
Daisy: Samsung provides one year standard warranty for the device from the date of purchase. Unfortunately, physical or liquid damage are not covered under warranty service cost includes accordingly.
david: so then the screens for a CDMA Note 3 and a GSM Note 3 are the same?
david: if so, can you provide me with the part #?
Daisy: I will explain you David.
Daisy: Samsung does not sell any spare part and we do not recommend to replace or repair the device LCD screen.
Daisy: It may void the device functionality.
david: yes
david: i understand.
david: the work would be performed at a local repair facility
david: however I was told that the LCD for a Sprint Note 3 was different than a T-Mobile Note 3 and was provided different repair costs.
david: this is why I'm trying to see if it's in fact the same part for every different carrier variant of the Note 3.
Daisy: I would like to inform that the Note 3 model is same for all Carrier.

This helped me a lot i was looking for a replacement for my N900W8 and was confused as what to buy, now i understand if you order the LCD only it can be istalled to any note 3, however if you happen to buy it with the frame then im afraid you'll only be able to install it to that specific carrier/model you bought it for unless you also buy the usb flex AND the corresponding back cover for that frame. Thank you for this post OP

This makes alot of sense. I was wondering why there were n900A and n900T assemblies on ebay that said they weren't compatible with each other. So I guess to get the best price, it's wise to buy the frame and the lcd/digitizer seperately and just use the self adhesive on it for a quick install. I'm glad to hear the connections for the lcd will work perfectly with the main board.

Sorry if this bumps this but I found this tread via a google search so I want to set the record straight that if it part includes the frame around the glass and LCD the parts are not compatible and could have a price difference.

[Q] N9005 LCD Replacement

Hi guys,
What i wanna ask you is a bit technical.
I got a screen burn-in on my N9005.
I am about to replace the LCD, but the problem is to find the LCD replacement in my country. Samsung only sells N900 here. And they couldn't help me to replace my screen. I found that N900's LCD are available here. Can I use the N900 LCD to replace mine?
Yes I know that I could order the N9005 LCD from ebay or alibaba. But it will take a time.
Please help. Thank you.
Hi, so did you fixed yours ? I am wondering the same thing.
Can I use lcd from the n9000 model for my n9005 version ??
I can't be fully sure, but I see no reason why the LCDs should be different. Ask the Samsung guys, how it is different from Exynos to Snapdragon.

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.

New motherboard

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

Replacing S10+ motherboard

Hi everybody... So let's start to form the beginning
I have an s10+ model SM-9575U1 and his motherboard is broken at all and I live in Brazil, so basically you cannot find another SM-9575U1 model so easily, Here goes my question (I know it sounds stupid, but...) its possible to put another motherboard model like SM-G975F, or maybe buy a used s10+ model SM-G975F and change some pieces like my battery and screen in this another model? Or maybe someones know where could I buy for a reasonable price another motherboard?
The c port pcb is likely different and there could be other incompatibilities.
