G930W8 mainboard replace - Samsung Galaxy S7 Questions and Answers

Is it possible replace mainboard G930W8 to G930F? I have bricked G930W8 and living in Europe

G930W8 and G930F are the same motherboard layout (it's written right on the board "G930F/W8") so it will definitely fit. The daughterboards are model-specific, which I believe is due to the antenna configuration. I would stand to be corrected on that. I'm not sure that it's going to cause you any problems if you didn't have any signal/channel issues with the W8 before it became bricked.
There are sellers online selling the G930W8 and G930F motherboards as directly interchangeable, for what that's worth.

So the problem can only be with the antenna? Thanks for reply

Replacing the motherboard on the S7

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?

S8+ G955FD LCD digitizer replacement

I have a blurry spot on my screen, a Samsung S8+ G955FD (dual sim). I can only seem to find replacements for G955, G955F, which from what I gather are single sim phone parts. Will that still fit with no problems?
If not does anyone know where I can purchase the correct screen and digitizer from? I will have to have it shipped to my country.

Questions about Parts Replacement for S7

I am planning to do a part replacement for my old Samsung Galaxy S7 -- G930FD.
Does anybody know if the G930F's OLED Display Assembly is the same as G930FD.
If the battery is the same, which I think it is.
Also is the back cover the same.

G930F & G930FD are literally the same device with literally the same everything (except for the FD part obviously), there's tutorials to change single SIM G930F into a dual SIM G930FD, so yes, they are the same.
G930F & G930FD both are the same devices.

Replace Broken Screen | can i SWAP from exynos <==> snapdragon

Hello to forum,
I just broke my screen from my Note 20 Ultra 5G (Snapdragon) Chinese model SM-N9860
The thing is that i am in Europe and we only have international model (Exynos).
My question is this, can i put exynos display to snapdragon? And if so, am i going to have signal? Cause i've heard that the antenna paths are different.
Thank you
I know the C port PCB is likely incapable.
Check by part numbers.
I spoke with Samsung Support while ago. And I thought to replace something, camera glass and front glass and they said there isn't issue to fix US variant in UK. So I think there isn't problem to use front glass from exynos model.
If the part numbers are the same you'll be ok.
Otherwise probably not.
Have u any idea if this part is ok?
Galaxy Note 20 Ultra 5G SM-N986 - White (GH82-23596C) (50027164) for my SM-N9860 ?​
You need to compare the P/Ns between the two variants.
Someone here may have tried it and can say for sure if it's the same variants.
A repair shop experienced in these can probably tell you too.
Otherwise don't bet on it.
Little suggestion.
If you still are within warranty period then don't repair it your self or anyone that is non certified samsung technician.
Doing so will make rest of your warranty invalid, so send it back to store where you bought it or send it to samsung and let them repair it.
In my case, Samsung mexico repair my 986U1, same case, in the country sales exynos but the part is the same, they change the internal parts because the screen not sale separately, only inconvenient is they not replace the batery like with the national devices service included

Transplanting motherboard

Hello can I take a v500n motherboard and put it in a non korean non international v50? I understand the rear pogo pins wont be available unless I put the korean v500n rear cover on the body of the non korean phone.
I was told by a highly LG Phone educated person that the v500n motherboard will not work in a Verizon LG v50 body. I assume this is due to the different antennas/hardware located off the main motherboard. If anyone can shed light on this to confirm for me I would love that.
Questions though.
Can a korean rear cover fit onto a non korean body?
Will the Korean motherboard work with the non korean screen?
Where are the antennas located, if I transplant only the korean motherboard will I also need the korean cellular antenna or is it located on the board itself?
Thank you for any help with this.
I appreciate everything.
