its easier to just buy a new housing unit on ebay. The dummy models don't have a digitizer in the screen, and are not normally able to be taken apart.

[Q] Galaxy Note 2 Motherboard replacement

Hey all,
I have a tmobile galaxy note 2 t889 that has a broken screen (glass, digitizer, and lcd screen). I have a friend that has a note 2 that has a bad esn, I was just wondering that if I took my motherboard from my phone which has a good esn and swapped it into his phone would that fix the bad esn problem or is the esn number tied to something else besides the motherboard?
Thanks in advance

Do you think is possible convert a N910c in dual Sim version N9100

Hello everybody...
Anyone knows if is possible convert a normal N910c in a dual Sim version of Galaxy Note 4 N9100? I just thinking, if is possible of course, change the the normal flex part that hold one Sim card for a new one with a double Sim card holder and change the middle housing too, for the same as N9100 uses to fit the new parts. On eBay I find this two parts, anyone have some idea if this is gonna work? Is necessary some firmware implements? The Note 4 is a awesome smartphone and I noob here just thinking if this go work with it.
Thanks people. You're the best.
The parts on sale in eBay. I can't post the links to this part here, noob haha, but if you wanna know who are this part, search on eBay for "OEM Double SIM Card SD Card Holder Flex Repair For Samsung Galaxy Note 4/N9108W" and "For Samsung Galaxy Note 4 N9100 N910F N910X Battery back Full Housing Cover Door".
That's all.
Mmm not really... at least not with these parts. There's a chance to convert it but I'm sure that you would need to buy the main dual-sim pcb and the back housing itself. The double sim flex will not work in the N910C mainboard. Cheers!
Do you think I need a new mainboard to this work? I was thinking that Samsung use a universal mainboard and add new components to her to build the different models...
Well first of all both N9108W/N91000 are snapdragon variants while our N910C is an exynos one. If you're able to snap the dual sim board in the PCB, you will still need to use a dual sim-enabled firmware, and the only available dual-sim firmwares are for snapdragon processors so it will not work in your device. That's why you should buy a N91000 Snapdragon pcb and swap your Exynos one. Cheers!
Ok, I understand it, not worth the effort, is more easy change between models and I don't need to do this... But it was curious if this would work. Thanks!!!
There is actually a dual sim adapter for that. It's available for most phones, I used it for my Note 2 but the flex cable was too thick so it kinda bulged when I forced the adapter under the battery cover.

I know those adapters, but you need switch with them to receive the signal of one or another operator, right? Or both sim works the same time?

I THINK they work together. I can't confirm it as those adapters works on stock roms and I was using custom, so there was some issues trying to detect the sims.

simply not possible
Nope, unless you are a software developer and can alter the stock firmware for your N910C to support the use of dual SIMs.
Hey guys,
i will come back to the Topic from the opner.
i have the Galaxy Note 4 SM-910F with a Snapdragon 805 CPU, in this case i think that can be work.
But i thik the firmware / baseband must be changed to the firmware from the N9100 / N9108W.
Perhaps also the kernel?

replacing Android mainboard vs replacing iPhone mainboard question

So, when I replaced a mainboard in my Samsung galaxy S3 I basically had a new phone. I had a new serial number and a new IMEI and for all intents and purposes it was indeed a new phone(To me, anyways!).
My question is this: Will this be the same case if I were to replace the mainboard in an iPhone 7 or even an iPhone X?
Thanks in advance for any knowledgeable answers! much appreciated!!!
