galaxy s7 motherboard replacement

[Frank07]

All samsung galaxy s7 with different model numbers has the same layout of motherboards or different model has a different layout,

I meant to say the dimensions and layout of the PCB like screw holes, plugs, connectors on pcb etc. i am going to buy a motherboard for a s7 live demo unit, so i dont know which model number should the motherboard be. trying to convert it from LDU to a usable cellphone.

Thanks

Models G930A G930V G930T G930F G930FD G930P are physically all the same and what are you can find commonly. The difference between them is just how they are programmed before shipment since Samsung isn't big on shipping unlocked high end phones like other manufacturers.

GoodDay Delaro.

Thanks for your reply. So it means i can just buy one and put it in my galaxy s7 Live Demo Unit, the demo model i have is G930X so i think X is specific to demo models, what would you advise what shall i buy for this model, i can find 930T and P for 70 euros.

Buy Hey,, the main problem still exist,, WILL THE MOTHERBOARD MAKE THE DEMO WORK AS A NORMAL CELL PHONE? OR DOES IT LAKES ADDITIONAL HARDWARE..?

 

[delaro]

Does it have a fully Display Assembly and Battery? I'm assuming you have this and have taken it apart to see what you need? If not then you need to disassembly and verify what is in the Dummy.

I'm really sorry to bother you but could you give me some advice about my situation:
I install motherboard in sm-g930f from sm-g930u and after replacement the camera and the cell stop working. May be you know something about why can it be.
Thanks before for your answer

 

[delaro]

Stopped working?

Do you get any sign of charging?
Do you get anything at all on the screen? Have you tried booting to recovery?
Did you try unplugging the Camera or Cameras and rebooting?

 

[Roman_Sushko]

After I installed new motherboard from sm-g930u in my sm-g930f everything work great exept the camera " i seen message the camera failed when I try to start it, and I can't use phone aplication becouse doesn't work cell. I tried unplug camera, pluged again, reboot several times. I changed firmware several times. Nothing helps.
I can booting to recovery without any problems

 

[delaro]

Did you wipe the Cache and try a recovery with the Camera unplugged? I would replace the Camera module regardless, it's not uncommon for them to die when you do a disassembly.

Hi @Frank07,

I am thinking about doing the same thing with a couple of g930x I picked up on Ebay. How did your motherboard swap go? Was everything you needed in the "X" model, except for the motherboard? My understanding is that the "X" demo models are actually missing the radio chips needed for cellular communication -- but those radios are mounted on the motherboard as I understand it. Hopefully I am correct. Anyway, please let me know how it went.

Thanks,
Philip
